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

What it does

U.S. Customs and Border Protection (CBP) is revising its regulations pursuant to the Trade Act of 2002 requiring the transmission of export manifest data electronically in the Automated Commercial Environment (ACE) for cargo transported by rail for any train departing the United States. This rule mandates the electronic transmission of rail export manifest information, identifies the parties eligible to transmit information, and describes the time frames prior to departure in which the information is due. This rule enables CBP to address important cargo security concerns while providing efficiencies to the trade.
