CBP title: ACE Truck Manifest Enhancement: New Carnet Data Elements Coming March 24
This message is from March 6, 2026. Later CSMS messages may have changed it. See the latest trade news
What did CBP announce?
CBP announced that on March 24, 2026 it enhanced the Automated Commercial Environment (ACE) to let trade users include ATA Carnet information in electronic truck manifest filings. The update involved electronic data interchange (EDI) changes. CBP referred filers to an attached information notice for details.
What is Allied's position?
This was a system enhancement for truck manifest filers and did not require action from importers or shippers. It concerned how carrier and broker EDI systems transmit carnet data to CBP, not the goods or duties on an entry. Clients do not need to act on this notice; if a specific truck shipment involving an ATA Carnet needs review, ask Allied about that entry.
General information, not legal advice.
What does the CBP message say?
On March 24, 2026, U.S. Customs and Border Protection (CBP) will enhance the Automated Commercial Environment (ACE) to enable trade users to provide ATA Carnet information as part of an electronic truck manifest filing. This update includes electronic data interchange (EDI) impacts.
