Two documents often sit at the centre of a commercial shipment: the commercial invoice explains the goods and transaction; the packing list explains how those goods are packed. Their details should tell a consistent story. Prepare them early enough for the relevant customs professional to review the shipment’s specific requirements.
Give each document its proper role
The U.S. International Trade Administration identifies the commercial invoice as a key clearance document used to assess duties and taxes. Its required format and content can vary by destination. The packing list describes package contents, weights and measurements. It complements the invoice; it does not replace it.
| Document | Main question it answers |
|---|---|
| Commercial invoice | What goods form the transaction and what is their value? |
| Packing list | Which goods are in each package, and what are its measurements? |
Review the commercial information
Start with the legal names and addresses of the relevant parties, invoice reference and date. Describe each product accurately, then review quantities, unit values, total value and currency. Show the agreed sales terms clearly. Share origin and classification information with the customs professional for validation rather than guessing a code.
Descriptions such as “samples,” “accessories” or “general goods” may leave important questions unanswered. A description should help a reviewer understand what the item is. If the shipment is not a sale, explain the transaction type and ask how its value and documentation should be presented for the destination.
Match the documents to the physical shipment
Number or mark the packages and list what each contains. Distinguish net product weight from gross packed weight. Record the final package count and outside dimensions, including pallets or crates. If ten cartons are placed on one pallet, make both levels clear instead of presenting eleven unrelated packages.
For example, an invoice listing 100 identical components should reconcile with a packing list showing five cartons of 20 components each. Package labels should follow that same numbering. If the supplier changes quantities or packing, update both documents and circulate the new version before collection.
Agree who issues the final documents and who checks them. Keep a clearly identified final version with the shipment record, rather than circulating several files that all look current. If a correction is needed after the documents have already been shared, explain what changed and send the revised version to the parties reviewing or handling the cargo. A consistent record helps everyone work from the same information.
A final consistency check
- Party names, document references, product descriptions and quantities agree.
- Currency, declared values and sales terms are clear.
- Package marks, gross weight and measurements match the finished cargo.
- Country and product-specific requirements have been reviewed before shipping.
Common questions
Are these the only documents I need?
Not necessarily. Required documents depend on the countries, cargo and transaction. Ask the relevant customs professional to confirm the complete list before shipping.
