Commercial Invoice

Definition

A commercial invoice is the seller's bill for the goods. It states the buyer and seller, description, quantity, value, country of origin, and terms of sale, and is a primary source document for customs valuation and the ISF.

Why it matters

Customs valuation and several ISF fields come from the commercial invoice. Mismatches between the invoice, the B/L, and the packing list are a leading cause of filing corrections.

What the commercial invoice must contain for customs

For U.S. import customs purposes, a commercial invoice must include the seller and buyer's full names and addresses, a detailed description of the goods (not a trade name alone), the quantity in the units of the HTS classification, the unit price and total value, the currency, the country of origin, and the Incoterm. CBP requires that the invoice value represent the actual transaction value, meaning the price paid or payable between unrelated parties. Undervalued invoices, where the declared value is lower than the actual transaction price, are a common source of penalties and post-entry audits.

Invoice-to-packing-list-to-B/L reconciliation

Three documents must agree for a clean customs filing: the commercial invoice, the packing list, and the bill of lading. The invoice states the value and description. The packing list states the physical counts, weights, and dimensions. The bill of lading states the container and cargo details as accepted by the carrier. A quantity on the invoice that does not match the packing list creates a discrepancy that the customs broker must resolve or flag before filing. A commodity description on the B/L that differs from the invoice creates a valuation question. These reconcile-step failures are the leading cause of entry corrections, which cost time and sometimes penalty.

The role of the commercial invoice in related-party transactions

When the buyer and seller are related parties, for example a U.S. importer buying from its own overseas subsidiary, CBP requires additional documentation to establish that the relationship did not influence the invoice price. The First Sale valuation method allows importers in some cases to declare the price of the first sale in the supply chain (manufacturer to middleman) rather than the last sale, which can reduce the dutiable value. Both of these require careful invoice documentation and, in most cases, prior disclosure to CBP or a customs ruling. Forwarders whose customers have related-party transactions should flag this to the customs broker, not assume the invoice can be used at face value.
