What is a Commercial Invoice?
A commercial invoice is an official document issued by the seller (exporter) to the buyer (importer) that details the transaction between them. For customs purposes, it is the primary document used by CBP (US Customs and Border Protection) to: determine the applicable customs value, calculate import duties and taxes, verify the country of origin, and confirm the accuracy of the shipment declaration. Unlike a pro-forma invoice (used for quotations), a commercial invoice represents an actual sale and must reflect the true transaction value.
