Exporting from China: The Customs Document Checklist

Most customs delays are not caused by the goods — they are caused by paperwork. Get the documents right at origin and clearance is routine; get them wrong and a shipment can sit while corrections are made. Here is the document set that keeps China exports moving.

The core documents

Almost every export shipment needs these four:

• Commercial invoice — the value, description, quantity and terms of sale. Customs uses it to assess duty, so the description and value must be accurate and consistent with everything else.
• Packing list — what is in each carton or pallet: contents, quantities, weights and dimensions. It lets customs and the carrier verify the shipment without opening every box.
• Bill of lading (or air waybill) — the carrier’s receipt and transport contract, and for ocean freight the document of title.
• Export declaration — filed with Chinese customs to authorise the goods leaving the country. Your forwarder typically prepares this.

Documents that depend on the goods or destination

Beyond the core set, you may need:

• Certificate of origin — proves where the goods were made. Often required to claim preferential duty rates under a trade agreement, sometimes mandatory for the destination.
• MSDS / dangerous goods declaration — for batteries, chemicals, aerosols and other regulated cargo.
• Fumigation / phytosanitary certificate — for wood packaging, plants or food products.
• Product-specific certificates — CE, FDA, inspection or test reports depending on the destination market and product type.
• Letter of credit documents — if you are paid by L/C, every document must match the credit’s wording exactly, or the bank can reject it.

Where shipments get held up

A few avoidable issues cause most delays:

• Value or description mismatch between the invoice, packing list and declaration.
• Vague descriptions — “parts” or “samples” instead of a clear, classifiable description.
• Wrong or missing HS code, which drives duty and admissibility.
• Wood packaging without treatment marks, which can trigger inspection or rejection at destination.

A simple discipline that pays off

Prepare the commercial invoice and packing list first, make sure they agree with each other, and let everything else — the declaration, the B/L, the certificates — reference the same figures. Consistency across documents is what customs officers look for; when the paperwork tells one clean story, clearance is fast.

The bottom line

A clean, consistent document set is the single biggest factor in smooth customs clearance. A regional forwarder who handles the declaration and checks the paperwork at origin catches the mismatches that otherwise surface — expensively — at destination.
