Correcting ACE Portal Importer Data Before an IEEPA Tariff Refund Claim

The Supreme Court ruled IEEPA tariffs unconstitutional in February 2026, and CBP has already processed about $121.75B in refund claims. Roughly 93.5% of eligible importers have not filed. For those who have, a quiet problem keeps surfacing: the importer data sitting in CBP's Automated Commercial Environment (ACE) does not always match the entity trying to claim the refund. The claim stalls, and the money sits with CBP a while longer.

This post covers what CBP actually checks in ACE when it reviews an IEEPA tariff refund claim, the most common data defects, and how to fix them before you file or while a claim is pending. If you are using the CAPE portal, a few minutes of ACE hygiene can be the difference between a payment and a rejection notice.

What CBP Matches When It Reviews a Refund Claim

CBP does not take your word for who paid the duty. It validates the claim against the entry data it already holds: the entry summary, the importer of record (IOR) number, the bond on file, and the ACH refund account linked to that IOR. If the entity filing in CAPE does not line up with the IOR on the underlying entries, CBP flags the claim.

The core identifiers CBP reconciles include:

• Importer of record number, which is usually an EIN, and must be the same number that appears on each entry.
• Legal name and address tied to that IOR number in ACE.
• The continuous bond or single entry bond associated with the entries.
• ACH refund enrollment, since refunds go out electronically within roughly 60 to 90 days including statutory interest.
• Entry line detail, including HTS classification, country of origin, and the duty programs applied.

Any mismatch in the first four items sends the claim into manual review or outright rejection. That is why ACE cleanup is not optional.

Four Importer Data Problems That Sink Refund Claims

1. Stale or wrong addresses on the IOR record

CBP sends correspondence to the address on file. If a company moved offices three years ago and never updated ACE, CBP notices go nowhere. The claim may be procedurally incomplete before you ever learn there was a problem.

2. Multiple EINs and successor entities

Companies that reorganized, changed entity type, or acquired another importer often have entries under two or more IOR numbers. If the current legal entity files one consolidated claim, CBP will only pay on entries matching the IOR number in the claim. The rest need separate treatment, and sometimes a successor in interest showing.

3. A broker's IOR number instead of yours

Some smaller importers let a customs broker use its own IOR number on entries. This is the single most damaging data problem for IEEPA tariff refund purposes, because the refund right follows the IOR of record. Fixing this usually means correcting the entry data under 19 CFR Part 173 or documenting why the correct party is the rightful claimant.

4. Missing or unverified ACH refund account

CBP pays refunds by ACH. If the IOR has no active ACH refund account in ACE, payment cannot go out even after approval. Enroll and verify the account before filing, not after.

How to Review Your Own ACE Data

If you have an ACE portal account, you can pull your importer record and entry data directly. Focus on four things:

• Confirm the legal name and address on your IOR record match your current corporate registration.
• Pull a Trade Activity Report covering the IEEPA duty period and confirm every entry was filed under your IOR number.
• Check that your bond is active and in the correct amount for the volume of entries involved.
• Verify ACH refund enrollment and test that the bank account details are current.

Do this before you file anything in CAPE. If you do not have portal access, CBP's ACE Support team can help you regain it, but that process takes time. Start it early, especially with a refund deadline of February 4, 2027 for fentanyl-related tariffs on China, Mexico, and Canada, and April 5, 2027 for reciprocal tariffs on other countries.

Correcting Errors: What You Can Fix and How

Some errors are administrative and fixable in ACE. Others require a formal correction.

Administrative fixes

Address changes, contact information, and ACH account updates can typically be handled through the ACE portal or by contacting your assigned CBP account representative. Update these first, since CBP uses that information for every subsequent claim.

Entry-level corrections

If the IOR number itself is wrong on an entry, you are dealing with a post summary correction or a 19 CFR Part 173 correction, depending on timing. CBP has specific windows for each. Beyond those windows, you generally need a protest or a written request to CBP, and the strength of your documentation matters enormously. A refund partner can tell you quickly which path applies.

Successor and related entity issues

If your current company inherited the importing activity of a predecessor, you will likely need to show the chain of succession in writing, including acquisition documents and confirmation that the predecessor no longer exists as a separate importer. CBP does not accept informal claims of succession.

Why Timing Matters More Than Most Importers Realize

Correcting data takes weeks, not days. It involves CBP review, possibly broker coordination, and documentary evidence. If you wait until the weeks before a deadline to start, you may run out of time to fix anything. And because roughly 93.5% of eligible importers have not yet filed, CBP's processing queues will only get longer.

The practical takeaway: treat ACE data cleanup as the first step of the refund process, not the last. Fix your IOR record, verify your bond, confirm ACH, and pull your entry data. Then file.

When to Bring In Help

If your ACE data is clean, filing an IEEPA tariff refund claim is straightforward. If it is not, or if you have multiple IOR numbers, entries filed under a broker's number, or a past corporate reorganization, the complexity rises fast. Tarisol connects importers with licensed specialists who file IEEPA tariff refund claims through CBP's CAPE portal. Fees are success-based, with no upfront cost. Find out what you could recover before the deadline passes.
