At customs clearance, the commercial invoice is the first document authorities reach for: it evidences the sales contract between seller and buyer and provides the basis for tariff classification, customs valuation, and import duty calculation. Mandatory fields include a precise description of the goods, quantity, unit price, total value, full details of shipper and consignee, and the agreed Incoterm. Customs authorities worldwide require it as standard – an incomplete or missing invoice typically causes delays and may trigger penalties. Insurers also rely on it when assessing cargo claims, and importers need it for accurate bookkeeping. It is distinct from the proforma invoice, which serves only as advance information or supporting documentation for letters of credit and carries no payment obligation.
