The commercial invoice (CI) is a request for payment (kind of like a bill) sent by the manufacturer or seller of goods to the buyer or exporter. The CI should have the entire history of business communications regarding that shipment, however it is important for the buyer to check the terms and conditions of the CI once it is received. On the CI, the shipment will be fully explained in order to easily identify the shipment. This document will also explain how the shipment is prepared correctly in order to gain entry into the destination country. It is very important that the CI be correct, since it will be used by customs to determine duties and fees, and will also be used to write all other documents connected with the shipment.
