ACE to Allow ATA Carnet Electronic Truck Manifest Filing

Posted by Timothy Miller on 3/19/26 5:00 PM

In a Cargo Systems Messaging Service (CSMS) bulletin published on March 17, 2026, U.S. Customs and Border Protection (CBP) announced that the Automated Commercial Environment (ACE) would be enhanced to allow users to provide ATA Carnet information as part of an electronic truck manifest filing.

This change will enable manifest filers to select “Carnet” as a bill of lading type in the truck manifest trade portal, giving CBP visibility in advance to help reduce processing time.

This ACE enhancement will go into effect on March 24, 2026.
