The number of AES filings depends on the details of the transaction and how they compare to the definition of a shipment listed in FTR Section 30.1(c). A shipment is defined as,” All goods being sent from one USPPI to one consignee located in a single country of destination on a single conveyance and on the same day.” It is possible to have multiple Internal Transaction Numbers for one booking or bill of lading. For each shipment, the applicable proof of filing, exemption, or exclusion citation has to be included on the commercial loading documents. The FTR does not regulate commercial loading documents; as a result, for additional questions, please contact U.S. Customs and Border Protection.
