A container can sit at a US pier for an extra week over one blank field: an invoice showing “35,000” with no currency, a broker unwilling to guess dollars or NT, two days of back-and-forth, a missed free period, demurrage running. Documents are the cheapest link in the logistics chain — and the one where errors cost the most disproportionately. Printing the page costs nothing; one wrong field can eat the shipment’s margin.
The baseline: every shipment
- Commercial Invoice: parties, description, quantity, unit and total price, currency, trade term — the document both customs use to establish value and duty
- Packing List: contents per carton, counts, net and gross weights, measurements, marks — must reconcile with the invoice
- Bill of Lading / AWB: the carriage contract and delivery instrument, per the shipper’s confirmed details
- Export declaration: filed by the broker against the above; most goods need no export permit, controlled items excepted
Added by cargo profile
- Certificate of Origin: when the buyer’s customs or L/C requires it — preferential and non-preferential COs are different instruments, and the wrong one forfeits the preferential rate
- Export permits / agency documents: controlled goods, strategic high-tech items, some food and agricultural products
- Inspection / quarantine certificates per commodity and destination
- The full L/C document set: on letter-of-credit shipments the credit’s terms govern — one wrong word is a discrepancy
- US-lane additions: ocean shipments need ISF data before loading; food carries its own FDA pre-filings
The four fields everyone misses
Checklists get memorized; fields cause the holds. From our Taiwan-US experience, the four highest hit rates:
- Shipping marks: the packing list says N/M while the cartons carry marks — or the reverse. At exam that is a document-cargo mismatch and a full count. Marks must agree three ways: documents, cartons, goods
- Origin statements: “Made in Taiwan” missing from the invoice, or formatted against the buyer’s customs practice; on the US lane, marking and declaration must also agree, and third-country routings need origin files ready in advance
- The HS six digits: export declaration and import entry disagreeing sends both customs digging separately. Align the first six digits with the buyer or their broker first — the rate stakes are in the tariff calculation article
- Currency and trade terms: unmarked amounts, Incoterms without a version year, or terms contradicting the freight structure (FOB with ocean freight included) — all reopen valuation
The price of one wrong field, computed
A 40-foot container reaches LA; the invoice currency is missing and the broker bounces it: two working days of confirmation, the free period gone, terminal storage and demurrage accruing daily; draw a documents exam on top and add 3–7 days. Late-delivery penalties and buyer confidence are not yet in the bill. On an L/C shipment the same error becomes a discrepancy fee taken straight out of the proceeds. The signature of document errors: the fix is fast, and every wait it triggers is priced in days and dollars.
