What must match between the bill of lading, the commercial invoice and the packing list?

Three documents, one container

The three documents describe the same cargo from three sides. The commercial invoice is the seller's bill: what was sold, to whom, at what price and on what terms. The packing list is the seller's list of how the goods are packed: cartons, lots and weights, row by row. The bill of lading is the carrier's receipt for the cargo and its contract to carry it. When it is made out "to order", it also controls who can take delivery at destination.

Each document has a job of its own, so each carries details the others leave out: the price on the invoice, the lot rows on the packing list, the vessel and the freight terms on the bill of lading. But many facts appear on more than one of them, because all three describe the same container. Those shared facts are the ones that must match.

What must agree

In short: everything the documents say about the same shipment. That means the container (its number and the seal on its door), the quantity (the cartons and the weights), the goods, the companies that send and receive them, and the route, where a document names the ports and the vessel.

Agreement does not mean identical wording. A bill of lading often describes the goods in a few words, while the invoice gives the full description, and that is normal. What a set may never do is say two different things about the same fact: two seal numbers for one container, two carton totals, two ports of discharge.

The rules behind it

The clearest rule comes from the banks. Under a letter of credit, a bank examines the documents alone, not the goods (UCP 600, article 14(a)). Data in one document "need not be identical to, but must not conflict with" data in the other documents or in the credit (article 14(d)).

For the goods, UCP 600 sets two levels. The commercial invoice must describe the goods as the credit does (article 18(c)). The other documents may describe them in general terms, as long as they do not conflict with the credit (article 14(e)). So "FROZEN PORK" on a bill of lading can sit next to a full description on the invoice.

Dates are not meant to match. Each document has its own date, and the one that counts as the shipment date is the on-board date on the bill of lading, or its issue date when there is no on-board notation (article 20(a)(ii)).

The ICC writes down how banks apply these rules in the International Standard Banking Practice, ISBP 821, published in 2023. Outside letters of credit, customs officers and food inspectors read the same documents side by side. In the Philippines, for example, the National Meat Inspection Service treats inconsistent information on the import documents as an adverse finding at the cold store (Memorandum Circular 5-2023-011, described by USDA in January 2025).

Why it matters

The ICC estimates that 65 to 80% of documents presented under letters of credit are refused the first time, and it names data that conflict between documents among the usual causes. A refusal costs a bank fee, and worse, the bank is no longer bound to pay: the money then waits until the buyer accepts the documents. What a refusal costs is in letter of credit discrepancies.

For a frozen container, time costs money too. The buyer needs the original documents to take delivery, so a set that is stopped at a bank or by an inspector leaves the reefer waiting at the port. A mistake found on a draft costs an email. The same mistake found at destination costs days.

An example

Alba Frost A/S in Denmark sells one 40-foot reefer container of frozen pork shoulder to Harborline Foods Inc. in Manila (the names are made up). The invoice, the packing list and the bill of lading give the same container number, 1,100 cartons and the same weights. The bill of lading says "FROZEN PORK SHOULDER", while the invoice gives the cut and the packing in full: general terms against a full description, which is no conflict.

One value does not agree. The bill of lading, the invoice and the health certificate give the seal as 4471852; the packing list says 4471825. Two digits are swapped, so one document names a seal that is not on the container door. The packing list must be corrected before the originals are sent. Under a letter of credit, a bank can refuse the set for it.

The whole set for one frozen container, including the health certificate and the destination's own rules, is in the export document checklist for a frozen container. Weights are explained in gross weight vs net weight on a packing list, the parties in consignee vs notify party, and the terms in the shipping document glossary.
