The commercial invoice is the primary evidence customs uses to assess a shipment. It establishes what the goods are, what they are worth, where they were made, who is selling and who is buying, and on what commercial terms. Every other document is checked against it. When an officer selects a shipment for review, the invoice is what they read first, and a document that raises a question is a document that generates a hold. Almost all of the errors that cause those holds are preventable at the point the invoice is typed.
Vague goods descriptions are the most frequent cause. Entries such as gift, samples, spare parts, machine, accessories or textile products do not allow an officer to verify the classification, and an unverifiable classification invites reclassification or a request for further information. A usable description states what the item is, what it is made of, what it does and what it is used for, in ordinary language, line by line. Model numbers and internal SKU codes can support the description but cannot replace it. If a line contains multiple different articles, it needs to be split, because one description cannot cover goods that fall under different HS codes.
Value errors are the second cause and carry more consequence, because they engage customs valuation rules rather than administrative ones. Declaring a value below the transaction value invites a valuation query and a reassessment of duty. Declaring samples or replacement parts at zero or at a nominal value is a common error; goods supplied free of charge still have a customs value and still need a realistic one, marked clearly as being for customs purposes only. Discounts, rebates and commissions that reduce the invoiced amount must be documented rather than silently applied, and moulds, tooling or design work supplied to the factory free of charge may need to be added to the declared value. Currency must be stated explicitly and must be the currency of the actual transaction.
Inconsistency across the document set causes holds even when every individual document is internally correct. The invoice, packing list, bill of lading or air waybill, and certificate of origin must agree on consignee legal name, quantities, carton counts, gross and net weights, shipping marks and goods descriptions. A packing list showing a different carton count from the bill of lading, or a certificate of origin describing the goods differently from the invoice, is a discrepancy an officer is obliged to resolve. These mismatches usually come from documents prepared by different people at different times rather than from any intent to mislead, which is precisely why a single reconciliation check before departure catches nearly all of them.
Missing structural fields stop an entry from being filed at all. An invoice needs a unique number and date, the full legal names and addresses of seller and buyer, the tax or registration identifiers the destination requires, the Incoterms rule together with the named place, the country of origin stated per line rather than once for the whole invoice, the HS code per line where the destination expects it, unit prices and total value with currency, quantities with units of measure, and the payment terms. The Incoterm without its named place is incomplete and cannot be interpreted. Where the buyer and the party paying are not the same, or the goods ship to a third country, that arrangement needs to be visible on the face of the invoice rather than explained later.
Corrections are always cheaper before departure. Once goods have arrived, amending a declaration means a formal amendment procedure, and the shipment usually waits while it is processed, accruing storage or demurrage. We review documentation as part of our customs clearance and brokerage service, and the most useful moment to send an invoice for review is while the cargo is still at the factory. Send us the draft invoice and packing list with the booking details and we will come back within one business day.
