On September 30, 2025, U.S. Customs and Border Protection (CBP) will update the Automated Commercial Environment (ACE) Secure Data Portal (ACE Portal) to support electronic refund transactions, in accordance with Executive Order 14247.   
 
The enhancements will enable authorized trade users to provide U.S. bank information in the ACE Portal, facilitating electronic refunds from CBP via Automated Clearing House (ACH).  
 
IMPORTANT: CBP will not transition to electronic-only refunds on September 30, 2025. This ACE Portal enhancement is a preparatory step to facilitate CBP’s future transition to electronic-only refund transactions, which CBP will announce at a later date.  
 
CBP also announced these changes in the Federal Register :: New Functionality Pertaining to Electronic Refunds in the Automated Commercial Environment on September 24, 2025. 
 
For more information about the enhancements, including links to a training guide and an upcoming user support call, see the Information Notice for Trade Users.
