Ask an export clerk what the rule is and you will usually hear "everything has to match". It is a reasonable thing to believe and it is not what UCP 600 says. The actual standard is looser in one direction and stricter in another, and people who over-apply the matching instinct create discrepancies of their own making.
Data in a document, when read in context with the credit, the document itself and international standard banking practice, need not be identical to, but must not conflict with, data in that document, any other stipulated document or the credit.
Two obligations, pulling in opposite directions. You are not required to make documents identical. You are required to make sure they cannot be read as contradicting each other. Everything practical about document preparation follows from the gap between those two things.
What does not conflict
- "Bremen, Germany" on one document and "Bremen" on another. Same place, no contradiction.
- A gross weight of 12,480 kg and 12,485 kg on two documents. Two weighings of the same consignment.
- "Steel fasteners" on a bill of lading where the credit and invoice say "Stainless steel hexagon bolts M10x50, DIN 933, A2-70". A general description that the specific one falls inside.
- An invoice dated after the bill of lading date. Nothing requires an invoice to precede shipment.
- A beneficiary address on the invoice that differs from the credit, so long as it is in the same country.
What conflicts
- Port of loading Hamburg on the bill of lading, Bremerhaven in the credit. Two different places, one of them wrong.
- Gross weight 12,480 kg against 15,900 kg. Not a measurement difference, a different consignment or a different figure.
- "Stainless steel bolts" on the invoice where the credit says "galvanised steel bolts". Not more general, different.
- 18 pallets on the packing list, 20 on the bill of lading. Countable things that do not agree.
- A certificate dated after the shipment it certifies, where the credit requires pre-shipment inspection.
The test in every case is whether a careful reader looking at both documents would have to conclude that one of them is wrong. Different levels of detail are not conflict. Different facts are.
The invoice is the exception, and it is stricter
There is one document where "need not be identical" does not apply to the goods description, and it is the one people most often relax.
The description of the goods, services or performance in a commercial invoice must correspond with that appearing in the credit.
"Correspond with" is a higher bar than "not conflict with". The invoice description has to reflect what the credit says, not a tidier version of it, not a shortened version, and not your internal product naming. If the credit describes the goods across four lines with a specification and a standard reference, the invoice carries that description.
In documents other than the commercial invoice, the description of the goods, services or performance, if stated, may be in general terms not conflicting with their description in the credit.
So the two rules point in opposite directions and both are routinely misapplied. Invoices get abbreviated when they must not be. Transport documents get padded out with the full credit description in the belief that matching is safer, which is unnecessary and occasionally introduces a contradiction that a two-word general description would never have created.
Copy the credit's goods description into the invoice. Leave it general everywhere else. The instinct to make all documents identical is wrong in both directions.
Four rules that resolve most of the remaining arguments
Addresses. The beneficiary's and applicant's addresses do not have to match the credit exactly, as long as they are in the same country as the addresses the credit gives. Contact details given as part of an address, telephone, fax, email, are disregarded. But there is a carve-out that catches people: when the applicant's address and contact details appear as the consignee or notify party on a transport document, they must be as stated in the credit. So an address that is fine on your invoice can be a discrepancy in the notify field of a bill of lading.
The shipper or consignor of the goods indicated on any document need not be the beneficiary of the credit.
Shippers. This one line removes a whole category of imagined problems. A freight forwarder, a manufacturer, a group company can appear as shipper on the transport document without the credit being breached. Beneficiaries regularly ask carriers to reissue documents to fix a non-problem.
Documents with no stated content. Where a credit requires a document other than a transport document, insurance document or commercial invoice, but does not say who issues it or what it must contain, the bank accepts it if its content appears to fulfil the function of the document required. A credit asking for a "certificate of analysis" without further specification is asking for a document that looks like a certificate of analysis.
A document presented but not required by the credit will be disregarded and may be returned to the presenter.
Extra documents. Sending more than the credit asks for does not help and is not neutral in practice. The bank disregards the extra document, so it cannot cure anything, but it is one more piece of paper carrying data that could be read as conflicting with the rest. There is no upside.
Where this leaves you when preparing a set
The useful mental model is not a matching exercise. It is: take every fact that appears in more than one place, and check that no two statements of it could be read as contradicting each other. Ports, dates, quantities, weights, marks and numbers, party names, the credit reference. Those are the fields where conflicts live, because those are the fields that appear repeatedly.
It is dull, mechanical work across five to twelve documents, done under time pressure at the end of a shipment, by someone who has already read these documents several times and will therefore read what they expect rather than what is there. That is not a knowledge problem, and no amount of expertise fixes it, which is the honest argument for having something else do the cross-comparison before the documents leave.
This article sets out the rules as we understand them and is not legal advice. What governs is the wording of the specific credit, the applicable ICC rules as in force, and the determination of the examining bank or customs authority in the individual case.
