CI — Commercial Invoice,Definition Summary: The official bill issued by the seller after a sale, used for customs clearance and payment.
The Commercial Invoice is a legally binding document that records the actual transaction. Customs authorities use it to assess duties and taxes, so it must accurately state the value, quantity, country of origin, HS code, and trade terms. Unlike the Proforma Invoice, it reflects a completed agreement and is a key document for payment collection, especially under L/C or T/T arrangements. Errors here can cause customs delays or fines.
