The packing list is the least glamorous document in international shipping — and one of the most checked. Customs officers, warehouse teams, and carriers all read it, and they all compare it against something else: the invoice, the cargo, the declaration. When those comparisons match, your shipment flows. When they don't, it stops.

What a packing list actually is

A packing list describes the physical shipment: what is packed, in how many cartons, how each carton is marked, and what everything weighs and measures. Unlike the commercial invoice, it carries no prices — its job is physical accuracy, not value. A typical line covers the carton range, the product inside, quantity per carton, net weight, gross weight, and dimensions.

What it must contain

  • Shipper and consignee details matching the invoice exactly
  • Invoice reference number linking the two documents
  • Carton-by-carton (or range-based) contents with quantities
  • Net weight, gross weight, and dimensions per carton and in total
  • Carton marks and numbers as they physically appear on the boxes
  • Total carton count and total volume (CBM)

Packing list vs commercial invoice

The invoice answers "what is this worth and who is buying it"; the packing list answers "what is physically in each box." Customs uses the invoice to assess duty and the packing list to verify the cargo. The two must tell one consistent story: same product names, same quantities, same parties. A packing list showing 480 pieces against an invoice showing 500 is exactly the kind of gap that converts a routine clearance into an inspection.

The mistakes that cause delays

The most common problems we correct before shipping: totals that don't add up across lines, weights copied from an old shipment instead of the real cargo, vague descriptions ("goods", "parts") where customs expects specifics, missing carton marks, and quantities that drifted after a supplier substituted or short-shipped. Every one of these is cheap to fix in China and expensive to fix at a destination port.

Who prepares it — and who should check it

Usually the supplier drafts the packing list, because they packed the boxes. But the supplier is not the party who suffers when it's wrong — the importer is. That is why our document review cross-checks the packing list against the invoice and, at pickup, against the physical cartons we count and measure. Verified numbers protect both your clearance and your freight quote.
