On February 6, 2026, U.S. Customs and Border Protection (CBP) began issuing all refunds electronically via Automated Clearing House (ACH) (subject to limited exceptions), as announced in the Electronic Refunds Interim Final Rule published January 2, 2026 in the Federal Register (FR Document 2025-24171). In preparation for this change, CBP improved the ACH refund sign-up process in the Automated Commercial Environment (ACE). CBP also recently added a feature for importers to add notify parties, also known as “Special Address Notification (CBP Form 4811) notify parties,” within the ACE Portal. 

CBP will hold a user readiness support call today at 2:00 p.m. ET to address trade community questions related to this transition.
