Packing List for Export: What It Must Include and Why Each Field Matters

A packing list looks like a simple inventory document. In an export transaction, it is one of the documents a bank examines when deciding whether to release payment. Here is what it must contain, and why getting each field right matters more than most exporters expect.

What a packing list actually does in an export transaction

A packing list (also called a packing slip or packing specification) is a document that describes the physical contents of a shipment: what is in each package, how it is packed, and how the total shipment breaks down by quantity, weight, and dimensions.

In international trade, the packing list serves three distinct functions. It is an operational document for the freight forwarder and customs authorities, telling them exactly what is being shipped. It is a reference document for the buyer, allowing them to verify the goods received against what was ordered. And it is a presentation document under a letter of credit (LC), where it forms part of the document set examined by the bank under UCP 600 (Uniform Customs and Practice for Documentary Credits, the international rulebook banks follow when examining LC documents) and ISBP 821 (International Standard Banking Practice, the detailed examination standard updated in July 2023).

That third function is where most errors occur. Exporters prepare packing lists thinking of the first two functions and underestimate how carefully the document will be read in the context of LC examination.

Required fields: what must appear on a packing list for export

1. Shipper and consignee details

The name and address of the shipper (exporter) and the consignee (buyer or their nominated party) must appear on the packing list. These must match the corresponding fields in the commercial invoice and the bill of lading. Under UCP 600 Article 14(d), documents other than the transport document do not need to be addressed to the applicant, but the details that do appear must not conflict with other documents in the set.

A common error: the invoice uses a full legal company name while the packing list uses a trading name or abbreviation. Even when both clearly refer to the same entity, inconsistency creates a discrepancy that the examining bank can raise.

2. Description of goods

The goods description on the packing list does not need to match the LC's goods description word for word. Under UCP 600 Article 14(e), documents other than the commercial invoice may use a general description of goods, provided it does not conflict with the description in the LC. The packing list can say "electronic components" where the LC specifies "Model XR-400 electronic control units" as long as the description is not in conflict.

However, any specific detail that does appear must be consistent. If the packing list includes product codes, model numbers, or grades, those must match what appears in the invoice and the LC. Partial descriptions that conflict with the LC cause discrepancies; general descriptions that are consistent with it do not.

3. Quantity per package and total quantity

The packing list must show the quantity of goods in each package and the total quantity of the shipment. This total must be consistent with the quantity stated in the commercial invoice. A packing list that shows 500 units across 10 packages while the invoice states 500 units is consistent. A packing list that calculates to 490 units while the invoice states 500 is a discrepancy, even if the difference is a labeling error.

The unit of measurement must also be consistent. If the invoice uses pieces, the packing list should not use sets or units unless those terms are clearly equivalent in context.

4. Package marks and numbers

Each package in the shipment should be identified with a mark and number (for example, "1/10, 2/10..." or "Case 1 of 10"). The packing list must reflect these marks and numbers accurately. If the LC requires specific shipping marks, those marks must appear on the packing list as well as on the packages themselves.

Shipping marks that appear on the bill of lading must match those on the packing list. A mismatch between what the transport document records and what the packing list states creates a cross-document inconsistency under UCP 600 Article 14(d).

5. Weight and dimensions

Gross weight, net weight, and package dimensions are standard packing list fields. Where the LC specifies weight or dimension requirements, the packing list figures must comply. Where the bill of lading records weight figures, those should be consistent with the packing list. Significant discrepancies in weight between the packing list and the transport document can raise questions about whether the documents describe the same shipment.

6. Number of packages and packaging type

The total number of packages and the type of packaging (cartons, crates, pallets, drums) must be stated and must match the bill of lading. The bill of lading records the number of packages received by the carrier. If the packing list shows 10 cartons but the bill of lading says 9 packages, the bank has a discrepancy regardless of the actual physical count at the port.

7. Reference to the LC or contract number

If the LC requires the packing list to reference the LC number, contract number, or purchase order number, that reference must appear exactly as specified. A missing reference where one is required is a discrepancy. An incorrect reference number is also a discrepancy, even if the correct number appears elsewhere in the document set.

The cross-document consistency rule

Under UCP 600 Article 14(d), data in a document does not need to mirror the wording in the LC or other documents, but it must not conflict with them. Every field on the packing list that touches a field on another document in the set is a potential point of discrepancy.

Fields the LC may additionally require

Beyond the standard fields, individual LCs may require additional information on the packing list. Common additional requirements include: country of origin, heat treatment or fumigation certification references, inspection certificate numbers, specific labeling language or format, and seal or lock numbers for containers. Any requirement stated in the LC that is not satisfied by the packing list as presented constitutes a discrepancy.

Reading the LC field by field before preparing the packing list is the single most effective way to catch these requirements before document preparation begins.

The most common packing list errors in LC presentations

Quantity totals that do not reconcile with the invoice. The most frequent packing list discrepancy. Even a rounding difference of one unit creates a conflict that the bank must raise.

Package count that does not match the bill of lading. The carrier records what they received. If the packing list was prepared before the final loading count was confirmed, the numbers may drift.

Shipper or consignee name formatted differently from the invoice. Legal name versus trading name, abbreviated address versus full address, different punctuation in the company name.

Missing LC-specific requirements. A required reference number, shipping mark, or certification note that appears in the LC conditions but was not carried through to the packing list.

How T flow L/C Checker handles packing list examination

T flow is a full-stack trade operations and trade finance infrastructure platform. Within that platform, T flow L/C Checker applies AI grounded in UCP 600 and ISBP 821 to review the full document set before presentation, including the packing list.

The system checks packing list fields against the LC conditions, verifies quantity consistency with the commercial invoice, and checks package count consistency with the bill of lading. Issues are flagged with the specific rule that applies, so the exporter knows exactly what needs to be corrected before submitting to the bank.
