Updated August 2026: The ACH mandate took effect February 6, 2026 — enrollment is now required to receive any CBP refund, including CAPE refunds. If you haven't enrolled yet, do it before filing a PSC, protest, or CAPE declaration so your refund isn't held up.
Introduction
On February 6, 2026, Customs and Border Protection fundamentally changed how importers receive refunds. The Electronic Refunds Interim Final Rule, published January 2, 2026 in the Federal Register, mandates that all CBP-issued refunds be processed exclusively through Automated Clearing House (ACH) electronic transfers. For importers who still haven't enrolled in CBP's ACH refund program, enrollment remains an urgent action item—until you enroll, your refunds face delays or processing complications.
This regulatory shift affects every importer who has ever received or may receive a refund from CBP, including duty drawback payments, refunds from Post Summary Corrections, and any other CBP-initiated reimbursements. With IEEPA/CAPE refunds now flowing, understanding what changed and how to enroll is essential for maintaining smooth import operations.
What's Changing on February 6, 2026
The End of Paper Refund Checks
Under the new Electronic Refunds Interim Final Rule, CBP will no longer issue paper checks for refunds. All refunds will be transmitted electronically via the Automated Clearing House (ACH) network directly to the importer's designated bank account. This transition applies to:
- Duty refunds from Post Summary Corrections (PSCs)
- Drawback payments
- Refunds resulting from protests
- Any other CBP-initiated refund payments
Limited Exceptions
While the rule mandates electronic refunds as the default, CBP has acknowledged that limited exceptions may apply in specific circumstances. However, importers should not assume they qualify for an exception. The prudent approach is to enroll in ACH refunds immediately to ensure uninterrupted access to any refunds owed.
Why CBP Is Making This Change
This modernization effort aligns with broader government initiatives to streamline payment processing, reduce administrative costs, and improve security. Electronic transfers are faster, more traceable, and eliminate the risks associated with paper checks—lost mail, check fraud, and processing delays. For importers, ACH refunds typically arrive within days rather than weeks, improving cash flow and reducing administrative burden.
Key Improvements to the ACE Portal
In preparation for this mandatory transition, CBP has recently enhanced the Automated Commercial Environment (ACE) Portal to streamline the enrollment process:
New Automated ACH Refund Authorization Tool
CBP has added an automated ACH Refund Authorization tool within the ACE Secure Data Portal. This new feature allows importers to:
- Submit ACH refund authorization electronically
- Update banking information securely
- Verify enrollment status in real-time
- Manage refund preferences for their import accounts
Streamlined Importer Account Applications
The ACE Portal's importer account application process has also been automated. This is particularly important because access to the new ACH Refund Authorization tool requires an active importer account in the ACE Portal. If you don't already have an ACE Portal account, you'll need to establish one before you can enroll in electronic refunds.
How to Prepare: Step-by-Step Enrollment Guide
Step 1: Review CBP's Electronic Refund Enrollment Reference Sheet
CBP has published an Electronic Refund Enrollment Reference Sheet that provides detailed instructions for the enrollment process. This document should be your primary resource for understanding the specific requirements and steps involved.
Step 2: Verify Your ACE Portal Access
Before you can enroll in ACH refunds, you need an active account in the ACE Secure Data Portal. If you don't have one:
- Visit the ACE Portal registration page
- Complete the importer account application (now automated for faster processing)
- Wait for account approval and activation
Step 3: Gather Required Banking Information
To complete ACH enrollment, you'll need:
- Bank name and address
- Bank routing number (ABA number)
- Account number
- Account type (checking or savings)
- Authorization from an authorized company representative
Step 4: Complete ACH Refund Authorization
Once your ACE Portal account is active:
- Log into the ACE Secure Data Portal
- Navigate to the new ACH Refund Authorization tool
- Enter your banking information
- Submit the authorization form
- Verify your enrollment status
Step 5: Confirm Your Enrollment
Don't wait to check your status. Confirming your ACH enrollment now ensures any issues are resolved before you need to file a refund claim.
CBP Support Calls Held During the Transition
To help the trade community prepare for the mandatory transition, CBP held user readiness support calls on the following dates:
Wednesday, January 14, 2026
Time: 2:00 PM - 3:00 PM ET
Format: Microsoft Teams
Wednesday, January 28, 2026
Time: 2:00 PM - 3:00 PM ET
Format: Microsoft Teams
Wednesday, February 11, 2026
Time: 2:00 PM - 3:00 PM ET
Format: Microsoft Teams (Post-implementation support)
Those calls covered enrollment questions and post-implementation troubleshooting as the ACH mandate took effect.
What Happens If You Haven't Enrolled?
Importers who have not enrolled in ACH refunds may experience:
- Delayed refunds: Without valid ACH authorization on file, CBP cannot process your refunds through the electronic system
- Administrative complications: Resolving refund issues without enrollment on file can require additional paperwork and processing time
- Cash flow impacts: Refunds that would normally process quickly can be held pending enrollment completion
The bottom line: there's no benefit to waiting. Enroll now — before filing a PSC, protest, or CAPE declaration — to ensure seamless refund processing.
