Purchase Order and Commercial Invoice

Where every shipment begins. The purchase order says what was agreed; the commercial invoice proves it to customs. Get these two right and most later problems never appear.

Lesson 1.1

What a purchase order tells you

You will learn to read a purchase order and extract the eight facts that determine the whole shipment.

A purchase order (PO) is the buyer's formal instruction to a supplier: these goods, this quantity, this price, these terms. It is a commercial document, not a shipping one, but it is where your shipment is really decided.

When a client sends you a PO, read it for these eight things before anything else:

  1. Who is buying and who is selling — full legal names and addresses, which must match your transport documents later
  2. What the goods are — specific descriptions, not marketing names
  3. Quantity and unit of measure — 500 pieces and 500 cartons are very different shipments
  4. Unit price and total value — this becomes the basis of the customs value
  5. Currency
  6. The Incoterm and named place — this tells you which legs you are arranging
  7. Delivery date required
  8. Payment terms — particularly whether a letter of credit is involved, because that changes every document you produce
Common mistake

Skipping straight to the goods description and missing the Incoterm. If the PO says EXW and you have quoted door-to-door, you have priced legs the buyer may not be paying for — or missed legs nobody has arranged. The Incoterm is the first line to find, not the last.

Pro tip

If the PO mentions a letter of credit, stop and ask for a copy of the L/C itself before you produce a single document. The bank pays against documents that match the credit exactly. A tiny mismatch — an extra word, a different spelling of a company name — can stop payment for weeks.

Key takeaways
  • The PO is where the shipment is really decided, before any freight is booked
  • Find the Incoterm and named place first — they define what you are arranging
  • A letter of credit changes everything; ask for it before producing documents
Lesson 1.2

The commercial invoice, field by field

You will learn every field on a commercial invoice and why customs cares about each one.

The commercial invoice is the single most important document for customs. It is the seller's bill to the buyer, and it is what customs uses to decide the value of the goods, the duty owed and whether the shipment looks legitimate.

Why customs cares about each block

  • Seller and buyer details — establishes who is legally responsible. The importer's identification number (EORI in the UK and EU, or the local equivalent) must be correct or the entry cannot be filed.
  • Country of origin — decides the duty rate and whether preferential rates apply. Origin is where goods were produced, not where they were shipped from.
  • Incoterm — tells customs whether freight and insurance are already inside the price, which affects the customs value.
  • Description and HS code — determines the duty rate and any licensing requirements.
  • Value breakdown — goods, freight and insurance shown separately so customs can calculate the value correctly.
  • Weights and package count — must agree with the packing list and transport document.
Important to know

Show freight and insurance as separate lines rather than burying them in the goods price. Under most valuation systems these elements are treated differently, and separating them lets the declaration be made correctly. A single lump sum forces assumptions and can raise the duty payable.

Verify locallyRequired invoice fields, importer identification formats, valuation methods and acceptable certifications differ by country and change. Confirm current requirements with the relevant customs authority or your customs broker.
Key takeaways
  • The commercial invoice drives customs value, duty and clearance
  • Country of origin means where goods were produced, not shipped from
  • Show freight and insurance separately from the goods value
Lesson 1.3

Describing goods so customs accepts it

You will learn to write a goods description that clears, using a simple four-part formula.

Vague descriptions are the most common reason shipments are held. Customs officers need enough information to verify the classification without opening the container. "Parts", "samples", "gifts", "machinery" and "textiles" all fail that test.

The four-part formula

What it is + what it is made of + what it is used for + distinguishing detail

Poor descriptionAcceptable description
Auto partsBrake discs, cast iron, for passenger cars, 280mm diameter, unbranded
TextilesMen's T-shirts, 100% cotton, knitted, short sleeve, printed
ElectronicsWireless earphones, plastic housing with lithium-ion battery, Bluetooth, retail packed
Machinery partsStainless steel ball bearings, 22mm bore, for industrial pumps
Samples — no commercial valueFabric swatches, woven polyester, 20x20cm, for customer sampling, nominal value EUR 2 each
Common mistake

Writing "samples — no commercial value" and declaring zero. Customs still needs a value to assess duty against, even for free goods. Declare a realistic nominal value and mark the invoice "Samples — value for customs purposes only, not for resale". Declaring zero invites a hold and a valuation query.

Real-world example

A homeware importer declares 900 cartons as "kitchen goods". Customs selects the container for examination because the description could cover anything from wooden spoons to knives, which carry very different duty rates and controls. The container is unloaded, inspected and reloaded. The delay is nine days, the examination costs several hundred pounds, and the duty turns out to be exactly what was declared. Every penny of that was avoidable with a proper description.

Pro tip

Write descriptions in plain English, and never in the supplier's marketing language. "AquaFlow Pro 3000" means nothing to customs. "Electric water pump, 750W, for domestic central heating" means everything.

Key takeaways
  • Use what it is, what it is made of, what it is for, and a distinguishing detail
  • Never declare zero value, even for free samples
  • Avoid brand names and marketing terms — they carry no customs meaning
Lesson 1.4

Currency, payment terms and who pays

You will learn how payment arrangements shape the documents you must produce.

How the buyer pays decides how much document discipline the shipment needs. There are four common methods, in ascending order of paperwork.

MethodHow it worksRisk sits withDocument pressure
Advance paymentBuyer pays before shipmentBuyerLow
Open accountGoods shipped, buyer pays laterSellerLow
Documentary collectionBank releases documents against payment or acceptanceSharedMedium
Letter of creditBank guarantees payment if documents comply exactlyBank, if documents complyVery high

Why letters of credit change your job

Under a letter of credit (L/C), the bank pays against documents, not against goods. Nobody inspects the cargo. If the documents match the credit exactly, the bank pays even if the goods are wrong. If the documents do not match — even trivially — the bank can refuse even if the goods are perfect.

Typical discrepancies that stop payment:

  • Company name spelled differently across documents ("Ltd" on one, "Limited" on another)
  • Goods description on the invoice not matching the wording in the credit
  • Documents presented after the credit's deadline
  • A claused Bill of Lading when the credit requires a clean one
  • Insurance certificate for less than the required percentage of value
Important to know

Under an L/C, copy the goods description from the credit word for word onto the invoice, even if the wording is clumsy or contains an error. The bank checks against the credit, not against what is sensible. If the wording is genuinely wrong, get the credit amended before shipping — never improve it yourself.

Verify locallyLetter of credit practice is governed by international banking rules and by the terms of each individual credit. Confirm requirements with the issuing or advising bank before presenting documents.
Key takeaways
  • Payment method determines how strict your documents must be
  • Under an L/C the bank pays against documents, never against goods
  • Copy the credit's goods wording exactly — amend the credit rather than the invoice
Lesson 1.5

Proforma invoice versus commercial invoice

You will learn the difference between the two, and when each one is used.

A proforma invoice is a quotation in invoice format. It looks almost identical to a commercial invoice but it is issued before the sale is agreed, and it is not a demand for payment.

Proforma invoiceCommercial invoice
IssuedBefore the sale is confirmedWhen goods are shipped
PurposeQuote, apply for an L/C, apply for an import licence, arrange paymentDemand payment, clear customs
AccountingNot a record of saleA record of sale
CustomsSometimes accepted for temporary or free-of-charge goodsThe standard document

Proformas matter in practice for three reasons: buyers use them to get internal purchase approval, banks use them to open letters of credit, and importers in countries with licensing regimes use them to apply for an import permit before committing to buy.

Common mistake

Sending a proforma to customs for a normal commercial shipment because the commercial invoice is not ready. Customs will usually reject it, and in some jurisdictions presenting the wrong document type is a compliance issue rather than an administrative one. Wait for the commercial invoice.

Pro tip

Make the proforma match what the commercial invoice will say as closely as possible — same description, same HS code, same terms. Where an L/C has been opened against the proforma, any later difference becomes a discrepancy and can stop the buyer's payment.

Key takeaways
  • A proforma is a quote in invoice format, issued before the sale
  • It is used for approvals, licences and opening letters of credit
  • Keep it consistent with the eventual commercial invoice to avoid discrepancies
Knowledge check

Module 1 review

Goods are manufactured in Vietnam, warehoused in Singapore and shipped from there. What is the country of origin on the invoice?

Origin follows production, not the port of departure. Getting this wrong changes the duty rate and can invalidate a preference claim.

An L/C describes the goods with a spelling error. What should the seller do?

Banks check documents against the credit's exact wording. Improving it creates a discrepancy. The credit must be amended, not the invoice.

Which description would most likely trigger a customs examination?

A description that could cover almost anything gives customs no way to verify classification, so the container gets opened.

Packing List and Weight Notes

The documents that describe the physical shipment. They are what everyone checks the cargo against — carriers, customs, warehouses and insurers.

Lesson 2.1

What a packing list is really for

You will learn who uses the packing list and why it must never contain prices.

The packing list describes how the goods are physically packed: how many packages, what is in each, what they weigh and what size they are. It contains no prices.

That last point matters. The packing list travels with the cargo and is handled by carriers, terminals, warehouse staff and inspectors. Keeping commercial values off it means the people handling the goods do not know what they are worth — useful for security, and a normal commercial courtesy where the buyer is reselling.

Who uses it, and for what

  • The carrier — to confirm package count and weight for loading and stowage
  • Customs — to verify what they find if they open the container
  • The warehouse — to check the delivery in and spot shortages
  • The insurer — to establish what was shipped when a claim is made
  • The buyer — to know which carton contains which items without opening all of them

Stackable No - do not double stack
Common mistake

Putting prices on the packing list "to be helpful". It tells everyone handling the cargo exactly what it is worth, and if the figures differ at all from the invoice, customs now has two conflicting value statements to query.

Pro tip

Always state stackability on the packing list. It is the cheapest line of text you will ever write and it prevents a forklift driver putting two tonnes on top of your client's goods.

Key takeaways
  • The packing list describes the physical shipment, never the prices
  • Carriers, customs, warehouses and insurers all check cargo against it
  • State stackability and packing type explicitly
Lesson 2.2

Marks, numbers and carton counts

You will learn how shipping marks work and why they are how lost cargo gets found.

Shipping marks are the identifying text printed on the outside of each package. When a pallet loses its paperwork — which happens constantly — the marks are the only way to tell whose it is.

A standard mark contains four elements:

  • Consignee reference — an abbreviation of the buyer, e.g. NTL
  • Destination — the port or city, e.g. BHX
  • Order or invoice reference — e.g. 2026-0884
  • Package number and total — e.g. 7/21, meaning carton seven of twenty-one

Written together: NTL / BHX / 2026-0884 / 7 of 21

Why "of 21" matters so much

Numbering each package against the total is what makes a shortage visible immediately. A warehouse receiving cartons numbered 1–6 and 8–21 knows instantly that carton 7 is missing, and can note it on the delivery document before signing. Without the total, nobody discovers the shortage until someone counts, which may be days later — by which time proving it went missing in transit is far harder.

Real-world example

A shipment of 30 unnumbered cartons is delivered. The receiver signs clean because the pallets look complete. Three days later, stock counting finds 28 cartons. The carrier points to the clean signature. There is no numbering to prove what was loaded and no note on the delivery document. The claim fails, and the importer absorbs the loss.

Important to know

Some destinations require additional marks — country of origin marking, handling symbols, or regulatory labels for specific product types. Requirements differ by country and product, so check before printing thousands of labels.

Key takeaways
  • Marks identify cargo when paperwork is lost
  • Number every package against the total, e.g. 7 of 21
  • Numbering makes shortages visible at delivery, when claims still succeed
Lesson 2.3

Gross, net and volumetric weight on paper

You will learn the three weights, calculate them yourself, and know which document shows which.

  • Net weight — the goods alone, with no packaging
  • Tare weight — the packaging: cartons, pallets, wrapping, dunnage
  • Gross weight — net plus tare, which is what the carrier handles

Gross = Net + Tare. Every document should show gross, and most should show net as well.

Worked example

18 pallets of packaged glassware. Each pallet holds 40 cartons at 9.2 kg of product each. Each carton weighs 0.4 kg empty. Each pallet weighs 22 kg, with 1.5 kg of shrink wrap.

  • Net per pallet = 40 × 9.2 = 368 kg
  • Tare per pallet = (40 × 0.4) + 22 + 1.5 = 16 + 23.5 = 39.5 kg
  • Gross per pallet = 368 + 39.5 = 407.5 kg
  • Shipment: net 6,624 kg, tare 711 kg, gross 7,335 kg

Volumetric weight

Volumetric weight converts space into a weight figure, because carriers sell space as well as weight. For air freight it is length × width × height in centimetres divided by 6,000.

Each pallet above measures 120 × 100 × 145 cm = 1,740,000 cm³. Divided by 6,000 that is 290 kg volumetric — less than the 407.5 kg actual, so this shipment would be charged on actual weight. Dense cargo usually is.

Common mistake

Declaring net weight where gross is required. It understates the shipment by hundreds of kilos, causes the transport document to disagree with the packing list, and on sea freight it makes the VGM declaration wrong — which is a safety regulation, not an administrative detail.

Pro tip

When a supplier gives you one weight figure with no label, always ask which it is. Assuming gross when they meant net is one of the most common causes of documents disagreeing with each other.

Key takeaways
  • Gross = net + tare; carriers work in gross
  • Volumetric weight converts space into kilos for charging
  • Never accept an unlabelled weight figure — ask which one it is
Lesson 2.4

Weight notes and weighbridge tickets

You will learn what independent weight evidence is, and when you will need it.

A weighbridge ticket is a printed record from a calibrated scale showing what a vehicle or container actually weighed. It is independent evidence, which is why it carries far more weight in a dispute than a figure typed onto a packing list.

When you need one

  • VGM declarations — Method 1 requires weighing the packed container on calibrated equipment
  • Bulk cargo sold by weight — grain, scrap, minerals, where the weight is the invoice
  • Overweight disputes — when a carrier claims the load exceeded limits and charges accordingly
  • Letters of credit — some credits require a weight certificate as a presented document

Weight notes and shortage claims

With bulk cargo, weighing at origin and at destination frequently produces different numbers. Small differences are normal — moisture, scale tolerance, residue left in the vehicle. Large differences mean either a measurement problem or a loss, and the two weighbridge tickets are what settle it.

Important to know

A weighbridge ticket is only evidence if the scale is certified and in calibration. A ticket from an uncalibrated scale can be challenged and usually is. Where weight genuinely matters commercially, check that the calibration reference appears on the ticket.

Pro tip

For any shipment where weight determines the invoice value, agree in the contract which weight governs — origin or destination — before shipping. This one clause prevents the most common bulk cargo dispute there is.

Verify locallyWeighing requirements, calibration standards and acceptable tolerances vary by country, commodity and contract. Confirm the applicable rules with the carrier, terminal or relevant authority.
Key takeaways
  • A weighbridge ticket is independent, calibrated evidence of weight
  • Needed for VGM Method 1, bulk cargo, disputes and some letters of credit
  • Agree in the contract whether origin or destination weight governs
Knowledge check

Module 2 review

A pallet holds 30 cartons of 11 kg of product. Cartons weigh 0.5 kg empty; the pallet is 20 kg with 1 kg of wrap. What is the gross weight?

Net 330, tare (15 + 20 + 1) = 36, so gross is 366 kg. Gross is what the carrier handles and what goes on the transport document.

Why should shipping marks show "7 of 21" rather than just "7"?

Numbering against the total lets the receiver spot a missing package and note it before signing. A clean signature followed by a later count usually kills the claim.

What should never appear on a packing list?

Prices belong on the commercial invoice. The packing list is handled by everyone touching the cargo, and conflicting values create customs queries.

Module 3 · 6 lessons

The Bill of Lading

The most powerful document in shipping. It is a receipt, a contract and — uniquely — a document of title that controls who can collect the cargo.

Lesson 3.1

What a Bill of Lading actually is

You will learn what the B/L is, who issues it, and when it appears in the shipment timeline.

A Bill of Lading (B/L) is issued by the carrier, or by a forwarder acting as carrier, once cargo has been received and loaded. It confirms what was received, sets out the terms of carriage, and controls delivery at the other end.

The timeline matters:

  1. Cargo is delivered to the carrierAt a terminal, depot or container yard.
  2. Cargo is loadedOnce on board, the carrier can issue a shipped on board bill.
  3. The B/L is issuedUsually a few days after sailing. Draft first, for checking, then originals.
  4. Documents travelOriginals are couriered to the buyer, or via banks under a letter of credit.
  5. Cargo is claimed at destinationThe carrier releases against an original B/L, or against a release instruction.
Important to know

The carrier will send you a draft B/L before issuing originals. This is your one easy chance to correct errors. Once originals are printed and released, corrections require surrendering all originals and reissuing — slow, sometimes chargeable, and occasionally impossible if they have already been couriered abroad. Check the draft properly.

Pro tip

Diary the draft B/L. Carriers often send it with a short window for amendments, and the email arrives among fifty others. Missing that window is one of the most common avoidable problems in export documentation.

Key takeaways
  • The B/L is issued by the carrier after cargo is received and loaded
  • It is receipt, contract and document of title in one
  • Check the draft carefully — correcting issued originals is difficult
Lesson 3.2

Its three jobs: receipt, contract, title

You will learn the three functions of a B/L separately, which is what makes the document make sense.

Job one: a receipt for the goods

The carrier confirms they received this cargo, in this apparent condition, on this date. If damage was visible at loading, they write a remark. A B/L with no damage remarks is clean. One with remarks is claused, and a claused bill can stop a bank payment entirely.

Note the phrase "apparent good order and condition". The carrier is confirming the outside looked fine. They did not open the cartons.

Job two: evidence of the contract of carriage

The terms on the reverse set out what the carrier promises, what they exclude, the time limits for claims and the maximum they will pay for loss. Almost nobody reads them. They are where the liability caps from Module 1 of the forwarding course actually live.

Job three: a document of title

This is the unusual one. With an original B/L, whoever lawfully holds the paper controls the cargo. The carrier releases the container to whoever presents an original. The document can be transferred, endorsed and sold while the ship is at sea — the goods change hands without anything physically moving.

Case study

A seller ships goods on open account to a new customer and couriers the originals straight to them. The buyer collects the cargo and then does not pay. The seller has no goods and no leverage.

Had the seller retained the originals until payment cleared, the buyer could not have collected the container. Same shipment, same carrier, entirely different outcome — decided by who held three pieces of paper.

Common mistake

Treating the B/L as just another shipping document to be filed. It is a negotiable instrument that represents the cargo. Losing an original is a serious event: replacing it usually requires a bank guarantee or an indemnity, often for a substantial percentage of the cargo value.

Key takeaways
  • The B/L is a receipt, a contract and a document of title
  • Clean means no damage remarks; claused can stop payment
  • Whoever holds an original controls the cargo — which is the seller's security
Lesson 3.3

Original, seaway bill and telex release

You will learn the three ways cargo gets released, and how to choose between them.

MethodHow release worksSeller's securityBest for
Original B/LConsignee presents an original at destinationHighNew buyers, letters of credit, unpaid goods
Telex releaseSeller surrenders originals at origin; carrier instructs destination to release without paperMediumShort voyages where paper cannot arrive in time
Seaway billNo title document; cargo released to the named consignee on identificationNoneGroup companies, prepaid or fully trusted buyers

The problem telex release solves

On a short route — Rotterdam to Felixstowe, say — the ship arrives in two days. The originals cannot physically get there first. Without a solution the container sits accruing storage while paper is couriered.

With a telex release, the seller surrenders all originals to the carrier at origin. The carrier messages the destination office to release without presentation. Crucially, the seller stays in control until they choose to surrender — so it is still a real decision point, usually taken once payment clears.

Common mistake

Agreeing a seaway bill to save time on a shipment that has not been paid for. A seaway bill gives the seller no control at all: the named consignee collects on identification. For an unpaid shipment to a new customer, it removes the only real security the seller had.

Pro tip

When a buyer pushes hard for a seaway bill on an unpaid shipment, the polite answer is telex release: they get the speed they want, the seller keeps control until surrender. It resolves the argument without either side losing anything they actually need.

Key takeaways
  • Originals give the seller maximum control; seaway bills give none
  • Telex release means surrendering originals at origin for paperless release
  • Match the method to how much the seller trusts the buyer, not to convenience
Lesson 3.4

Straight, order and bearer bills

You will learn the three consignment types and what the phrase "to order" means.

  • Straight (named) bill. Consigned to a specific named company. Only they can collect. It cannot be transferred to anyone else.
  • Order bill. Consigned "to order" or "to the order of [a bank or company]". It can be transferred by endorsement — signing it over on the reverse. This is what makes the cargo tradeable in transit.
  • Bearer bill. Whoever physically holds it can collect. Rare, and risky — losing it is close to losing the cargo.

Why banks insist on order bills

Under a letter of credit, the bank is financing goods it has never seen. Consigning the B/L "to the order of [issuing bank]" means the bank controls the cargo until the buyer pays or accepts the draft. Then the bank endorses the bill over to the buyer.

A straight bill consigned directly to the buyer gives the bank no security at all, which is why credits almost always require "to order" wording.

                              For the Carrier ____________________
Important to know

The notify party is not the consignee and has no right to the cargo. They are simply who the carrier contacts when the vessel arrives. On an order bill the notify party is usually the real buyer, so leaving it blank means the buyer never hears the ship has landed — and storage charges begin.

Pro tip

"Shipper's load, stow and count" means the carrier did not verify the contents — the shipper packed and sealed the container. It is standard on FCL and protects the carrier from claims about contents they never saw. Expect to see it; do not try to have it removed.

Key takeaways
  • Straight bills name one consignee; order bills transfer by endorsement
  • Letters of credit require order bills so the bank keeps control
  • The notify party gets the arrival notice but has no right to the cargo

  1. ShipperFull legal name and address, matching the commercial invoice exactly. Under an L/C, character for character.
  2. ConsigneeNamed party or "to order" — and is it what the payment arrangement requires?
  3. Notify partyPresent, with a working phone number and email. Blank here means nobody knows the ship arrived.
  4. Vessel and voyagePresent, and consistent with the sailing schedule you quoted.
  5. Ports of loading and dischargeCorrect, and specific. Not just a country.
  6. Container and seal numbersMatching the loading photographs and the packing list. A seal number mismatch is a serious red flag.
  7. Description of goodsMatching the invoice. Under an L/C, matching the credit's wording.
  8. Gross weight and measurementMatching the packing list and VGM declaration.
  9. Freight termsPrepaid or collect — and does it match the Incoterm? CIF means prepaid; FOB usually means collect.
  10. Number of originals, and clean or clausedStated on the face. Under an L/C, a full set is usually required.
Real-world example

A draft B/L shows gross weight 905 kg; the packing list says 950 kg. It looks like a typing slip and nobody queries it. At destination, customs notices the discrepancy between the transport document and the invoice package, selects the shipment for examination, and it is held for six days. The correction would have taken one email during the draft window.

Pro tip

Check the B/L against the packing list and invoice side by side, not from memory. Three documents open at once is how discrepancies get caught. Checking one document alone catches only obvious errors.

Key takeaways
  • Run the same ten-point check on every B/L, every time
  • Freight terms must match the Incoterm
  • Always check the B/L alongside the invoice and packing list
Lesson 3.6

What happens when the B/L is wrong

You will learn how to fix an incorrect B/L, and what a letter of indemnity really is.

If originals have not yet been released

Straightforward. Tell the carrier, get a corrected draft, approve it. Usually free, occasionally a small amendment fee.

If originals are already out

Harder. The carrier must retrieve every original before issuing replacements, because two valid sets in circulation would mean two parties could claim the same cargo. If the originals have been couriered to another country or lodged with a bank, retrieval takes time and may not be possible before arrival.

If an original is lost

The carrier will normally require a letter of indemnity backed by a bank guarantee, often for a significant percentage of the cargo value, held for a long period. This is expensive and slow, and it is why originals are treated like cash.

Important to know

Carriers are sometimes asked to release cargo without originals against a letter of indemnity, or to backdate a bill to meet an L/C deadline. A letter of indemnity for release without originals is a recognised commercial practice with real risk attached. Backdating a Bill of Lading is not — it is a false statement about when goods were shipped, and it can amount to fraud. Never do it, never suggest it, and escalate immediately if it is requested.

Common mistake

Treating a client's request to "just change the date, it's only two days" as a favour. It misrepresents the shipment date to a bank relying on it for payment. The two days are irrelevant; the misstatement is the problem.

Verify locallyThe legal status of letters of indemnity, release without originals and document amendment varies by jurisdiction and by carrier terms. Take qualified legal advice before agreeing to any of these arrangements.
Key takeaways
  • Fix errors at draft stage — it is trivial then and difficult later
  • Replacing issued originals requires retrieving every one of them
  • Release against indemnity is a recognised practice; backdating a B/L never is
Knowledge check

Module 3 review

A buyer has paid in full but the seller still holds all three originals. Who can collect the cargo?

The carrier releases against an original or a release instruction. Payment does not change that — the paper does. In practice the seller now arranges telex release or couriers the originals.

A letter of credit is in place. How should the consignee box read?

The bank is financing goods it cannot see. An order bill consigned to the bank keeps control with them until the buyer pays or accepts.

A client asks you to backdate a B/L by two days to meet an L/C shipment deadline. What do you do?

Backdating misrepresents the shipment date to a party relying on it for payment and can amount to fraud. An indemnity does not make it acceptable.

Air Waybill and CMR

The transport documents for air and road. Both look similar to a Bill of Lading and behave very differently — neither gives control of the cargo.

Lesson 4.1

The Air Waybill explained

You will learn what an Air Waybill does, and the one crucial way it differs from a Bill of Lading.

The Air Waybill (AWB) is the transport document for air cargo. It is a receipt and evidence of the contract of carriage — but it is not a document of title.

Why that matters enormously

Air cargo is released to the named consignee on identification. There is no original to present, nothing to withhold, nothing to endorse over to a bank. A seller shipping unpaid goods by air has no equivalent of holding the originals back.

So payment security on air shipments must come from somewhere else: advance payment, a letter of credit, or consigning the cargo to a bank or a forwarder who will only release on instruction.

Bill of LadingAir Waybill
Document of titleYesNo
Transferable by endorsementYes, if an order billNo
Release againstOriginal documentConsignee identification
Seller's control after shippingHighNone, unless consigned to a third party
Typical number issued3 originals3 originals, different purpose

The AWB's three originals are not for circulation. One is for the carrier, one travels with the goods to the consignee, and one is the shipper's copy.

Common mistake

Consigning an unpaid air shipment directly to the buyer, assuming the AWB gives the same protection as a B/L. It gives none. If security is needed, consign to a bank or to a forwarder at destination who holds the goods pending release instructions.

Important to know

The AWB number has a standard form: a three-digit airline prefix, then an eight-digit serial, written like 125-44718203. The prefix identifies the airline, which is useful when you need to trace a shipment and only have the number.

Key takeaways
  • An AWB is a receipt and contract, never a document of title
  • Air cargo releases to the named consignee on identification
  • Payment security on air shipments must come from the payment terms
Lesson 4.2

House documents versus master documents

You will learn why one shipment has two transport documents, and which one your client holds.

When a forwarder consolidates cargo, two documents exist for the same goods:

  • Master (MBL or MAWB) — issued by the actual carrier to the forwarder. Shipper: the forwarder at origin. Consignee: the forwarder's partner at destination.
  • House (HBL or HAWB) — issued by the forwarder to the real customer. Shipper: the actual seller. Consignee: the actual buyer.
Document example
ONE CONSOLIDATED CONTAINER - two document layers

  MASTER BILL  MEDUVL447182
    Shipper    Duran Freight Services SL     (the origin forwarder)
    Consignee  Northgate Logistics UK Ltd    (the destination partner)
    Cargo      1 x 40' container, 62 pallets, 21,400 kg

      HOUSE BILL  DFS-HBL-11204
        Shipper    Ceramica Duran SL
        Consignee  Northgate Tiling Ltd
        Cargo      21 pallets, 8,210 kg

      HOUSE BILL  DFS-HBL-11205
        Shipper    Levante Ceramics SA
        Consignee  Midland Stone Supplies Ltd
        Cargo      18 pallets, 6,900 kg

      HOUSE BILL  DFS-HBL-11206   ... and so on

The shipping line only knows about the master. They deal with one shipper and one consignee for a container holding cargo belonging to five different companies.

Important to know

If your client holds a House Bill, their contract is with the forwarder, not the shipping line. The line has no obligation to them and will not deal with them directly. This is normal and fine when the forwarder is sound. If that forwarder fails financially mid-voyage, cargo can be caught up in their unpaid account with the line.

Pro tip

For high-value cargo, ask at booking whether the client will receive a House or Master document. If it is a House, check the forwarder's standing — trade association membership, financial cover, how long they have traded. It takes ten minutes and it is the risk clients never think to ask about.

Key takeaways
  • Master is carrier to forwarder; House is forwarder to the actual customer
  • One container can carry many house consignments
  • A House document means your contract is with the forwarder, not the carrier
Lesson 4.3

The CMR note for road freight

You will learn what a CMR is, how its three copies work, and why box 24 decides claims.

The CMR note is the consignment note for international road freight between countries that are party to the CMR convention. Like the AWB, it is a receipt and contract but not a document of title.

The three copies

  • Copy 1 (red) — the sender keeps it
  • Copy 2 (blue) — travels with the goods and is given to the consignee
  • Copy 3 (green) — stays with the carrier

Box 24 — the most important box in road freight

Box 24 is where the consignee signs and stamps on delivery. It is the moment the cargo's condition is formally recorded, and it decides most road freight claims.

If goods arrive damaged and the consignee signs box 24 without remark, the law generally presumes the goods were delivered in good condition. Overturning that presumption later is difficult and usually fails.

Case study

A delivery of 14 pallets arrives in Rotterdam. Two are visibly water-stained. The warehouse operative is busy, signs box 24 clean, and unloads. Two days later the client opens the pallets and finds ruined goods worth several thousand euros.

The claim fails. The clean signature is evidence the goods arrived in apparent good order, and there is no photographic or written record from the delivery moment.

What box 24 should have said: "2 pallets water damaged, outer cartons stained and soft, goods not inspected, subject to full inspection and claim." Twelve words, written in thirty seconds, worth thousands.

Pro tip

Train anyone receiving goods to write what they see, not a verdict. "3 cartons crushed" is a fact. "Damaged" is vague. "Received subject to inspection" alone is often treated as meaningless boilerplate. Specific observations survive.

Verify locallyCMR applies to international road carriage between contracting states and does not cover domestic movements, which follow national law or the carrier's own terms. Claim notification deadlines and liability limits vary; confirm the applicable rules for your route.
Key takeaways
  • CMR is the international road consignment note — receipt and contract, not title
  • Three copies: sender, consignee, carrier
  • Box 24 decides claims — record specific damage before signing
Lesson 4.4

Delivery notes and proof of delivery

You will learn what makes a POD legally useful rather than just a signature.

Proof of delivery is evidence that goods were delivered, to whom, when, and in what condition. A weak POD is the reason many valid claims fail.

What a strong POD contains

  • Date and time of delivery — not just the date
  • Printed name as well as a signature. An illegible squiggle proves nothing about who accepted the goods.
  • Company name and delivery address as actually delivered
  • Package count received, written by the receiver, not pre-printed
  • Condition remarks, or an explicit statement that goods appeared undamaged
  • Reference numbers linking it to the consignment

Clean versus claused signatures

A clean POD records no problem. A claused POD carries a remark about damage, shortage or a refusal to check. Claused is not a failure — it is the receiver doing their job and preserving the right to claim.

Common mistake

Accepting "signed for — 1 pallet" as a POD when 14 pallets were delivered. Receivers often sign for one line because it is faster. If a shortage emerges later, the POD says one pallet was delivered and nobody can prove what arrived.

Pro tip

Photographs at delivery have become the most valuable evidence in freight claims, and every driver carries a camera. Where cargo is valuable or fragile, ask for photos as part of the delivery process. It costs nothing and settles disputes that paperwork alone would not.

Key takeaways
  • A useful POD shows time, printed name, count and condition
  • A claused POD preserves the right to claim; a clean one often ends it
  • Photographs at delivery are now the strongest routine evidence available
Lesson 4.5

Signing, stamping and keeping copies

You will learn what to keep, for how long, and in what form.

Documents are not filed for tidiness. They are filed because customs can audit an entry years after clearance, and because claims and disputes surface long after everyone has forgotten the shipment.

What a complete shipment file contains

  • Commercial invoice and packing list
  • Transport document — B/L, AWB or CMR
  • Customs declarations, both export and import
  • Any certificates: origin, inspection, dangerous goods, fumigation
  • Proof of delivery
  • Carrier booking confirmation and rate agreement
  • Correspondence about anything that went wrong
  • Photographs, where taken

How long to keep it

Customs record-keeping periods are commonly several years and differ by country. Claim time limits are usually much shorter but can be extended in litigation. The practical answer used by most forwarders is to keep complete shipment files for at least the longest applicable customs retention period, and never to delete anything connected to a dispute.

Important to know

Scanned copies are generally acceptable for customs audit, but requirements for originals differ — certificates of origin and some preference documents may need to be retained in original form. Confirm what your jurisdiction requires before relying on scans alone.

Pro tip

Name files consistently from day one: 2026-0884_INV.pdf, 2026-0884_BL.pdf, 2026-0884_POD.pdf. When a customs audit arrives three years later, a consistent naming scheme turns two days of searching into twenty minutes.

Verify locallyRecord retention periods, acceptance of electronic copies and requirements to hold original certificates vary by country and are subject to change. Confirm with the relevant customs authority or a qualified adviser.
Key takeaways
  • Keep a complete file per shipment, not scattered documents
  • Retention is driven by customs audit periods, not by claim deadlines
  • Some certificates may need to be kept as originals, not scans
Knowledge check

Module 4 review

A seller ships unpaid goods by air, consigned directly to the buyer. What protection does the AWB give?

An AWB is not a document of title. Security must come from payment terms, or from consigning to a bank or forwarder who releases on instruction.

Two pallets arrive visibly water damaged. What should the receiver write in CMR box 24?

Specific observations recorded at delivery survive; vague boilerplate is often treated as meaningless, and signing clean generally presumes the goods arrived in good order.

Your client holds a House Bill of Lading. Who is their contract with?

The House document is issued by the forwarder acting as carrier. The shipping line's contract is with the forwarder under the Master Bill.

Module 5 · 4 lessons

Certificates of Origin and Inspection

The supporting documents that reduce duty, satisfy regulators and get goods past border controls that would otherwise stop them.

Lesson 5.1

Certificate of origin: why it saves your client money

You will learn what a certificate of origin proves and the difference between the two kinds.

A certificate of origin (CO) states where goods were produced. Origin decides the duty rate, whether quotas or trade measures apply, and whether a preferential rate is available.

The two kinds

  • Non-preferential CO. Simply states the country of origin. Used for general customs purposes, trade statistics, letters of credit and some import licensing. Usually issued or certified by a chamber of commerce.
  • Preferential CO or origin declaration. Proves goods qualify for a reduced or zero duty rate under a trade agreement between two countries. This is the one worth real money.

What a preference is worth

Take a shipment of goods with a customs value of £80,000, where the standard duty is 6.5% and the preferential rate under an applicable trade agreement is 0%.

  • Without valid proof of origin: duty of £5,200
  • With valid proof of origin: duty of £0

The document that saves £5,200 is often a single page that takes ten minutes to obtain. Clients routinely fail to claim preference simply because nobody told them it existed.

Pro tip

Ask every import client one question: "Is there a trade agreement between the origin country and here, and are you claiming preference?" A surprising number are not, and finding them thousands of pounds a year is the fastest way to become indispensable to them.

Common mistake

Confusing where goods were shipped from with where they originate. Goods manufactured in one country and warehoused in another originate in the country of manufacture. Shipping from a country that has a trade agreement does not create eligibility — only actual origin does.

Verify locallyTrade agreements, preferential rates, proof requirements and issuing bodies vary by country and change with trade policy. Confirm current eligibility and documentation with the relevant customs authority or chamber of commerce before claiming preference.
Key takeaways
  • A certificate of origin states where goods were produced
  • Preferential proof can reduce duty to zero under a trade agreement
  • Origin follows manufacture, never the port of shipment
Lesson 5.2

Preferential origin and trade agreements

You will learn how goods qualify for preference, which is more demanding than clients expect.

Assembling goods in a country does not automatically make them originate there. Trade agreements contain rules of origin that set out how much work must happen locally. Three common tests:

  1. Wholly obtainedEntirely produced in one country — crops grown there, minerals extracted there, animals raised there. Straightforward and rare in manufactured goods.
  2. Change of tariff headingImported materials must be transformed enough that the finished product falls under a different HS heading from the inputs. Turning imported fabric into garments usually qualifies; repackaging usually does not.
  3. Value added thresholdA minimum percentage of the final value must come from local materials and processing — for example, no more than 45% of the ex-works price may be non-originating materials.
Case study

An importer buys bicycles assembled in Country A, which has a trade agreement offering zero duty. They claim preference. Two years later customs audits the entries.

The audit finds the frames, wheels, gears and brakes were all made in Country B and merely bolted together in Country A. Simple assembly did not meet the value-added threshold in the agreement. The goods never qualified.

Outcome: duty is reclaimed retrospectively across two years of imports, with interest. The importer had acted in good faith on the supplier's certificate — and in most systems the importer, not the supplier, carries the liability.

Important to know

Claiming preference is a legal statement by the importer. If it turns out to be wrong, duty is normally recovered from the importer with interest, whatever the supplier said. This is why keeping the origin evidence — supplier declarations, bills of materials, costings — matters as much as the certificate itself.

Pro tip

For any client claiming preference regularly, get a written supplier declaration confirming the goods meet the specific rule of origin, renewed annually. It does not transfer the legal liability, but it gives the client a documented basis for the claim and a route to recover from the supplier.

Verify locallyRules of origin differ for every trade agreement and every product category, and are amended over time. Confirm the exact rule applying to your goods with the relevant customs authority or a qualified customs adviser.
Key takeaways
  • Origin rules test transformation, not just assembly location
  • Common tests are wholly obtained, change of tariff heading and value added
  • The importer usually carries liability for a wrong preference claim
Lesson 5.3

Inspection, fumigation and health certificates

You will learn which shipments need extra certification and when to arrange it.

CertificateTypically needed forArranged
PhytosanitaryPlants, produce, seeds, timber, some plant productsBefore export, by the plant health authority
Veterinary / healthMeat, dairy, fish, animal productsBefore export, by the competent authority
FumigationWooden packaging, some agricultural goodsBefore loading, by a licensed operator
Pre-shipment inspectionCertain countries require it on many importsBefore shipment, by an appointed inspection company
Quality / conformityElectrical goods, toys, machinery, regulated productsVaries — often during production

ISPM 15 — the one that catches everyone

Solid wood packaging — pallets, crates, dunnage — used in international trade generally must be heat treated or fumigated and marked accordingly. Untreated wood can carry pests, and border authorities take it seriously.

If a container arrives with unmarked wooden pallets, the possible outcomes include treatment at destination, repacking, or the whole consignment being refused entry. Note the packaging is the problem, not the goods — a perfectly compliant shipment can be stopped because of the pallets it sits on.

Common mistake

Arranging inspection certificates after the goods have shipped. Almost all of these must be issued before export, by an authority in the origin country, often after physically examining the goods. Once the container has sailed, it is usually too late — which can mean the goods cannot legally enter.

Pro tip

Ask two questions at the quoting stage, not at booking: "What is the product made of, including its packaging?" and "Is there any wood, food, plant or animal content?" These two questions catch the overwhelming majority of certification surprises.

Verify locallyCertification requirements depend on the commodity, the origin country and the destination, and change frequently in response to disease and pest risks. Confirm current requirements with the relevant authority before shipping.
Key takeaways
  • Most certificates must be issued before export, in the origin country
  • ISPM 15 applies to wooden packaging, not the goods themselves
  • Ask about materials and packaging at quoting stage, not at booking
Lesson 5.4

Dangerous goods declarations

You will learn to recognise dangerous goods and understand why this is the one area where guessing is unacceptable.

Dangerous goods (DG), also called hazardous materials, are substances that pose a risk during transport. They are grouped into nine classes: explosives, gases, flammable liquids, flammable solids, oxidising substances, toxic and infectious substances, radioactive material, corrosives, and a miscellaneous class.

What people do not realise is dangerous

  • Lithium batteries — including those already inside laptops, phones, power tools and e-bikes
  • Aerosols — deodorant, spray paint, air freshener
  • Perfume and aftershave — alcohol content makes them flammable liquids
  • Nail polish, hand sanitiser, some cosmetics
  • Paints, adhesives, solvents, cleaning products
  • Magnets, above certain field strengths, in air freight

An e-commerce seller shipping cosmetics and electronics is frequently shipping dangerous goods without knowing it.

Important to know

Dangerous goods declarations must be prepared by someone trained and certified to do so, and the rules differ by mode — sea, air and road each have their own regime, with air being the strictest. Mis-declaring or failing to declare dangerous goods is a serious offence in most jurisdictions, and it endangers crews. Containers of undeclared goods have caused fatal vessel fires.

If you are not trained and certified, do not prepare these declarations. Refer the shipment to someone who is.

Common mistake

Accepting a client's assurance that "it's just cosmetics, it's fine". Ask instead for the safety data sheet for each product. That document states whether the goods are classified as dangerous and under which UN number. It is the only reliable answer, and any legitimate manufacturer can supply it.

Verify locallyDangerous goods regulations differ by transport mode and jurisdiction, are amended on a regular cycle, and carry legal penalties for non-compliance. Always work from the current regulations and use appropriately trained and certified personnel.
Key takeaways
  • Nine DG classes; many everyday retail products fall inside them
  • Lithium batteries, aerosols, perfume and paint are the common surprises
  • Always request the safety data sheet, and never prepare DG paperwork untrained
Knowledge check

Module 5 review

Bicycle parts made in Country B are bolted together in Country A, which has a zero-duty trade agreement. Does the bicycle qualify for preference?

Simple assembly rarely satisfies a value-added or tariff-heading rule. A supplier certificate does not make goods qualify, and the importer usually carries the liability.

A client ships perfume and cordless power tools. What must you establish?

Perfume is a flammable liquid and power tools contain lithium batteries. Both are commonly classified as dangerous goods, and the safety data sheet is the authoritative source.

A container arrives with untreated, unmarked wooden pallets. What is the risk?

ISPM 15 applies to the wood packaging regardless of the cargo. Compliant goods are routinely stopped because of the pallets they sit on.

Module 6 · 4 lessons

Checking Documents for Errors

The discipline that separates a competent documentation clerk from an expensive one. Most freight disasters were visible on paper days before they happened.

Lesson 6.1

The ten errors that stop shipments

You will learn the errors that cause most delays, ranked by how often they actually occur.

  1. Weight mismatch between documentsInvoice, packing list and transport document showing different weights. The most common error there is, and a reliable trigger for customs attention.
  2. Vague goods description"Parts", "samples", "assorted goods". Customs cannot verify the classification, so they examine the cargo.
  3. Company name inconsistency"Ltd" on one document, "Limited" on another; a trading name on one, the registered name on another. Fatal under a letter of credit.
  4. Wrong or missing HS codeWrong duty calculated, or the entry cannot be filed at all.
  5. Missing importer identificationNo EORI or local equivalent means no declaration can be made.
  6. Package count disagreement21 pallets on the invoice, 20 on the B/L. Something is wrong and customs will want to know what.
  7. Incoterm missing or impreciseCustoms cannot determine whether freight is inside the price; charges become disputed.
  8. Missing certificateOrigin, phytosanitary, DG paperwork not arranged before shipping — usually unfixable afterwards.
  9. Freight terms contradicting the IncotermA CIF shipment with a freight collect B/L. Somebody is about to be billed unexpectedly.
  10. Container and seal number errorsA seal mismatch suggests the container was opened, and is treated as a security concern rather than a clerical one.
Real-world example

An importer's invoice lists 21 pallets; the B/L says 20. The shipper had combined two part pallets at the last minute and updated only one document. Customs holds the container pending explanation. Clearing it takes four days of emails and a corrected invoice, plus port storage. The underlying cargo was entirely correct.

Pro tip

Nine of these ten errors are found by laying three documents side by side and comparing four fields: names, weights, package counts and descriptions. That comparison takes three minutes and prevents most of the delays you will ever encounter.

Key takeaways
  • Weight mismatches and vague descriptions cause the most holds
  • Name inconsistencies are minor commercially and fatal under an L/C
  • Nearly all of these are caught by a three-minute side-by-side comparison
Lesson 6.2

Cross-checking documents against each other

You will learn a structured cross-check method and practise it on a worked set.

Checking a document alone only catches obvious mistakes. Errors that stop shipments are usually disagreements between documents, and those are invisible unless you compare.

The method

Open the invoice, packing list and transport document together. Check these seven fields read identically across all three:

  1. Shipper name and address
  2. Consignee name and address
  3. Goods description
  4. Number and type of packages
  5. Gross weight
  6. Marks and numbers
  7. Container or vehicle reference

* Consignee differs by design: an L/C requires an order bill to the bank,
  with the buyer as notify party. This is correct, not an error.

ACTION: invoice shows 8,410 kg against 8,210 kg on two other documents.
Query the shipper BEFORE the draft B/L approval window closes.
Important to know

Not every difference is an error. Under a letter of credit the consignee on the B/L is deliberately the bank, while the invoice shows the buyer. Learn which differences are structural and which are mistakes — querying legitimate differences wastes everyone's time and makes people stop listening when you find a real one.

Key takeaways
  • Compare invoice, packing list and transport document side by side
  • Check seven fields: parties, description, packages, weight, marks, container
  • Know which differences are structural rather than errors
Lesson 6.3

Amending a document after issue

You will learn what can be corrected, by whom, and what it costs in time.

DocumentWho amends itDifficulty after issue
Commercial invoiceThe sellerEasy — reissue with a revision note
Packing listThe sellerEasy
Draft B/LThe carrierEasy, within the amendment window
Issued B/LThe carrierHard — all originals must be surrendered
Customs declarationThe declarantPossible, via a formal amendment procedure
Certificate of originThe issuing bodyHard — often requires reissue in the origin country

The rule that makes this easy to remember

Anything the seller produced can be corrected quickly. Anything a carrier, authority or chamber issued is slow, because it was issued by a third party who must formally withdraw and replace it.

Amending a customs declaration

Declarations can normally be amended, including after clearance, through a formal procedure. Voluntarily disclosing an error is generally treated far more favourably than having it found in an audit. Where duty was underpaid, the difference plus interest is usually due; where it was overpaid, a refund can often be claimed.

Pro tip

When you find an error after clearance, say so immediately and in writing. Voluntary disclosure is the single best thing you can do for a client in that position. Hoping nobody notices is how a correctable error becomes a compliance case.

Verify locallyAmendment procedures, disclosure regimes, time limits and penalty treatment vary considerably by country. Confirm the correct process with the relevant customs authority or a qualified customs adviser.
Key takeaways
  • Seller-produced documents are easy to correct; third-party ones are not
  • Amending an issued B/L requires retrieving every original
  • Voluntary disclosure of a declaration error is almost always the right move
Lesson 6.4

Building your own document checklist

You will build a reusable checklist you can apply to any shipment, on any lane.

Experienced operators do not remember what to check. They work from a list, because memory fails on a busy Friday and a list does not.

Document example

Pro tip

Keep the checklist to one page. A two-page checklist stops being used within a month. If you need to add something, remove something that has never once caught an error.

Common mistake

Building a checklist and then never revising it. Every time a shipment goes wrong, ask whether a checklist line would have caught it. If not, add one. A checklist that never changes is a checklist that stopped learning.

Key takeaways
  • Work from a written checklist, not memory
  • Structure it by stage: before booking, before movement, at draft, before arrival, after delivery
  • Keep it to one page and revise it after every incident
Knowledge check

Module 6 review

Which single check catches the largest share of document errors?

Most errors are disagreements between documents, and they are invisible unless you compare side by side.

You discover after clearance that the HS code used was wrong and duty was underpaid. What do you advise?

Voluntary disclosure is generally treated far more favourably than an error found at audit. Duty plus interest is usually due either way; the difference is how the case is handled.

Under a letter of credit, the B/L consignee is a bank while the invoice shows the buyer. Is this an error?

This is a structural difference, not a mistake. The bank holds control until the buyer pays, then endorses the bill over.
