A packing list is a shipping document prepared by the exporter or shipper that itemizes the contents of each package, carton, or pallet in a shipment. It includes the quantity of items, their descriptions, net and gross weights, and package dimensions. The packing list is one of the core documents required for customs clearance, alongside the commercial invoice and the bill of lading or airway bill.
Why It Matters for Importers
CBP and partner government agencies use the packing list to verify what is physically in a shipment and to match it against the commercial invoice and customs entry. Discrepancies between the packing list and the invoice — such as mismatched quantities, missing items, or weight differences — can trigger an examination, delay release, or raise compliance flags.
An accurate packing list also protects you in the event of cargo damage or loss. Insurance claims require documentation of what was shipped, and the packing list serves as the detailed inventory that the commercial invoice alone does not provide.
What a Packing List Should Include
- Shipper and consignee names and addresses
- Invoice number and date (matching the commercial invoice)
- Number and type of packages (cartons, pallets, crates, drums, etc.)
- Description of goods in each package
- Quantity per package and total quantity
- Net weight and gross weight per package and total
- Package dimensions (length x width x height)
- Shipping marks and package numbers
Common Issues
The most frequent problem is a packing list that does not match the commercial invoice. If the invoice shows 500 units but the packing list accounts for only 480, CBP may hold the shipment for examination. Similarly, if weight discrepancies suggest the shipment contains undeclared goods, the cargo may be selected for intensive inspection.
Ensuring your supplier provides an accurate, detailed packing list before the shipment departs is one of the simplest ways to prevent clearance delays. For more on the complete documentation required for importing, see our guide on customs clearance.
