Five checks before your cargo reaches customs

Match the invoice to the goods

Customs compares your commercial invoice against what officers see in the container. Values must reflect the real transaction price, quantities must match the packing list, and descriptions must say what things are — vague lines like "parts" invite examination. One afternoon aligning invoice and cargo prevents a week under hold. State the shipment's incoterms on the invoice as well: they decide who pays duty and freight, and mismatched incoterms between invoice and bill of lading are a classic trigger for questions.

Confirm every HS code

The six-digit classification decides your duty rate, and a single wrong digit can double it or flag the entry for review. Verify codes against the current tariff schedule rather than copying last year's entry, especially for mixed or upgraded products. When a code is genuinely ambiguous, get a ruling before the vessel sails. Keep a small register of the codes you use, with the reasoning for each — when a product changes or a new team member files, that register is what keeps classifications consistent from shipment to shipment.

Count against the packing list

Carton counts, weights and marks on the packing list must mirror the physical load exactly. Discrepancies — a short pallet, a restencilled carton — read as misdeclaration even when innocent. Photograph the loaded container and keep the tally sheet; both settle most questions in minutes. Pay attention to weight in particular: verified gross mass rules mean the declared container weight is a legal statement, and terminals can refuse or re-weigh boxes that look wrong. Weigh at the warehouse, not at the gate.

File early through your broker

Entries can usually be filed days before arrival, so there is no reason to meet the vessel with paperwork. Send documents to your broker the moment the container gates in at origin, confirm the entry number before discharge, and keep certificates of origin and licences attached. Cargo with a filed entry leaves the terminal; cargo without one waits. Finally, make sure your broker holds a current power of attorney and your importer details are up to date — expired authorisations are a surprisingly common reason filings bounce. A five-minute annual review with your broker keeps every future entry moving.
