Packing List vs Commercial Invoice: A Practical Guide

Two documents decide whether your cargo clears customs on day one or sits in a bonded warehouse racking up storage fees: the commercial invoice and the packing list. They look similar, they arrive together, and they contain many of the same fields — but they answer different questions and customs officers cross check them line by line.

What each document is actually for

• Commercial invoice answers "what does this cargo cost and who owns it?" — it drives duty calculation and payment terms.
• Packing list answers "how is this cargo physically packed?" — it drives CBM, gross weight, container fit and inspection.

Commercial invoice — required fields

• Exporter and importer full legal names and addresses.
• Invoice number, date, PO reference, currency.
• Incoterm and named place (e.g. FOB Shanghai, DAP Hamburg).
• HS code (6-digit minimum; many customs authorities want 8 or 10).
• Description of goods — not just "electronics" but the actual item.
• Country of origin.
• Unit price, quantity, extended total, grand total.
• Signature and stamp — many countries still require an ink signature.

Packing list — required fields

• Exporter, importer, invoice reference, date.
• Number of packages (cartons or pallets) with markings.
• Dimensions of each package (L × W × H).
• Gross weight and net weight per package and total.
• Total CBM (must match the bill of lading exactly).
• Contents of each package — SKU, quantity, item description.

The five most common mistakes

• CBM mismatch between packing list and bill of lading. The carrier will re-measure at the port and bill the higher figure.
• Missing net weight. Many customs authorities compute duty on net weight; leaving it blank triggers manual review.
• Vague description like "electronics" or "gift items." Use the same wording that maps directly to the HS code.
• Wrong Incoterm — DAP with no duty prepaid means the buyer pays customs; DDP means the seller does. Getting this wrong delays release by days.
• Rounded CBM — writing 12 CBM when the real figure is 12.47 CBM. Round only in your favour, and only at the invoice-total level.

How CBM ties the two documents together

Both documents show the shipment volume. Customs officers use the commercial invoice value plus the packing list CBM to sanity check density — if 40 CBM of cargo is invoiced at just $2,000, they flag under-invoicing. If 0.5 CBM is invoiced at $80,000, they flag misdeclaration of high-value goods as low-value freight.

Compute CBM once, from the master carton dimensions, in the CBM calculator, and paste the exact same number onto the packing list, commercial invoice and the forwarder's booking form.
