Export customs is the first hard gate in international logistics. Incomplete papers will stop even a perfectly booked sailing. The three core documents are the commercial invoice, the packing list and the customs declaration authorization.
A commercial invoice should at least name the goods in specific English (material and use — not just “gifts”), quantity, unit price, total value, Incoterm, country of origin and both parties. Declare the real transaction value; under-declaring invites exams and later penalties.
The packing list must match the cargo: pieces, gross and net weight, volume, container / seal numbers and packing type. List mixed SKUs by carton so exams are faster. Wood packing needs an ISPM-15 mark.
Three other frequent blocks: missing declaration elements (brand, model, composition), a wrong HS code (rebates and destination duty both move), and an expired authorization stamp. Batteries, cosmetics and food also need MSDS, ingredient lists or inspection papers in advance.
Ruitong pre-checks documents and pre-classifies HS codes so the first filing is more likely to clear. Send a draft invoice and packing list and we will mark what is still missing.
