Automated Commercial Environment (ACE) Export Manifest for Rail Cargo Test

This document announces that U.S. Customs and Border Protection (CBP) plans to conduct the Automated Commercial Environment (ACE) Export Manifest for Rail Cargo Test, a National Customs Automation Program (NCAP) test concerning ACE export manifest capability. The ACE Export Manifest for Rail Cargo Test is a voluntary test in which participants agree to submit export manifest data electronically at least 2 hours prior to loading of the cargo onto the rail car in preparation for departure from the United States or, for empty rail cars, upon assembly of the train. CBP regulations do not require carriers to submit a manifest for export rail shipments. This notice provides a description of the test, sets forth eligibility requirements for participation, and invites public comment on any aspect of the test.
