In international commodity trade the goods move on ships, trucks and pipelines, but the transaction moves on paper. Documents decide whether a buyer can take delivery, whether a bank will pay and whether customs will clear the cargo. A shipment that is right in every other respect can still stall on a single inconsistent certificate.
Why documents carry so much weight
Where payment is made by documentary letter of credit, banks examine the documents, not the goods: payment depends on presenting documents that comply with the terms of the credit. Customs authorities and receivers work the same way, relying on the paperwork to establish what the goods are, where they came from and who is entitled to them.
The core document set
| Document | Typically issued by | What it confirms |
|---|---|---|
| Commercial invoice | Seller | The goods, quantity, price and terms of sale |
| Packing list | Seller | Packing, weights and marks for packaged goods |
| Bill of lading | Carrier or its agent | Receipt of the cargo, the terms of carriage and, when negotiable, title to the goods |
| Certificate of origin | Chamber of commerce or other authorized body | Where the goods were produced |
| Certificate of quality or analysis | Independent inspection company or laboratory | That the product meets the agreed specification |
| Certificate of quantity or weight | Independent inspection company | The quantity loaded or discharged |
| Health or sanitary certificate | Competent authority in the country of origin | That food and agricultural products meet import requirements |
Depending on the product and the destination, the set may also include product registration, fumigation certificates, dangerous-goods declarations or legalized copies.
Where documentation goes wrong
- Discrepancies. A name, port or product description that differs between the invoice, the bill of lading and the letter of credit – even slightly – can hold up payment.
- Late originals. When the cargo arrives before the original documents, receivers face delays and demurrage, or delivery against a letter of indemnity.
- The wrong certificate. Certificates issued against the wrong standard, at the wrong point or by the wrong party do not meet the contract.
- Destination requirements. A document the importing country requires, but nobody listed in the contract, can stop the goods at the border.
Building documentation discipline
- Agree the full document list in the contract, including who issues each document and when.
- Match the document list to the letter of credit before shipment, not after.
- Check every document against the others for consistent names, quantities, dates and descriptions.
- Confirm the destination’s requirements with the buyer and, where needed, a customs broker.
- Keep a clear record of versions, courier details and electronic copies.
Every document should tell the same story about the same cargo.
How TAGT approaches documentation

This article is general guidance, not legal advice; documentary requirements depend on the product, the contract, the payment terms and the countries involved.
