Electronic Refunds Interim Final Rule Effective 2/6/2026
Effective February 6, 2026, U.S. Customs and Border Protection (CBP) will issue 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).
This rule will require trade members to set up ACE Portal accounts and to submit ACH banking information in the ACE Portal so that CBP can issue ACH refunds instead of mailing refunds as U.S. Treasury checks.

Ready to Get Started with ACH?
Getting set up with ACH is simple and straightforward. Just follow these steps:
Reference our ACH Guide below: For comprehensive instructions and details.
Ensure You Have a U.S. Bank Account: To use ACH, you'll need an account with a U.S. bank. Most Canadian banks have U.S. branches, so you might already be set!
Complete the Application: Fill out the ACH enrollment application form.
Submit the Application: Once completed, email the application along with supporting documentation to ach-customs@cbp.dhs.gov to get started with your ACH transactions.
While establishing your ACH account for Customs payments, you may inquire if your bank has any limits to the number of transactions allowed per day. Many banking institutions have low daily transaction limits to help curb fraud, but you may request higher limits to allow your trade activities to continue uninterrupted.
Don't forget to let your Deringer account representative know you have completed the application.
For more information on how to submit an application, please reference our ACH Guide below.
