This document amends the Customs Regulations to make provision for the Automated Export System (AES)--an electronic reporting system jointly developed by the Bureau of the Census (Census) and Customs that allows exporters to transmit commodity information contained on Shipper's Export Declarations and sea carriers to transmit outbound vessel manifest information. These amendments generally describe the AES, cross-referencing the applicable Census Regulations that will provide for the AES. They also set forth the criteria by which Customs will determine whether to approve an exporter for the option to transmit commodity information through AES after the carrier has left the United States (post-departure) and the appeal procedures for AES exporters if Customs denies the exporter the post-departure option; or, if Customs approves the post-departure option for the AES exporter, the grounds for revocation of the use of the option and the appeal procedures if Customs revokes the use of that option. This document also provides for the Sea Carrier's Module in the AES. These regulatory changes are designed to help exporters that utilize the AES realize the benefits of fewer delays in the processing of export information by Customs due to missing paperwork, and to provide for fewer and faster inspections of export shipments as well as reduced administration costs due to automation.
