7 Proven Tips to File Complaints and Recover Customs Fees in 2026

US importers and consumers who face incorrect customs fees, duties, or tariffs can file complaints and seek refunds through official U.S. Customs and Border Protection (CBP) processes. The main options involve submitting a protest with Form 19 or a labeled letter within set deadlines, enrolling in ACH refunds via the ACE Portal starting February 6, 2026, claiming duty drawbacks on re-exported or destroyed goods for up to 99% recovery, and using the four-step tariff refund process in the ACE/CAPE system amid potential refunds for importers.

These approaches cover overpayments from liquidations, rulings, IEEPA tariffs, or export situations. Begin by reviewing your entry status--whether liquidated or unliquidated--to decide on protests, prior disclosure statements (PSC), drawbacks, or ACH enrollment. Electronic refunds all require ACH authorization, though limited waivers exist.

Enroll in ACH Refunds for Fast Customs Fee Returns

Corporations and individual payees with an ACE Portal account need to use the “ACH Refund Authorization” tab to enroll and authorize ACH refunds, effective February 6, 2026. Once set up, overpaid customs fees return quickly to your bank account.

Here are the steps:

1. Log in to your ACE Portal account.
2. Navigate to the “ACH Refund Authorization” tab.
3. Enter your bank routing number, account number, and authorize electronic refunds.
4. Submit the enrollment.

If you encounter bank routing number errors, reach out to ACH Refund Support at extension 1178 or email [email protected]. The CBP ACH Refund page offers full details.

Limited waivers for the electronic refund requirement under 31 CFR 208.4 allow a U.S. Treasury check. Submit a written request that identifies the importer, refunds involved, and applicable waiver provision.

File a Protest to Challenge Incorrect Customs Decisions

You can dispute CBP liquidations or rulings by filing a protest on Customs Form 19 or a letter labeled "Protest." Submit within 90 days of liquidation notice for origin determinations or within 30 days for rulings, in line with post-2020 USMCA context.

The steps are:

1. Gather entry details, liquidation notice, and evidence of error (e.g., misclassification or valuation).
2. Complete Form 19 or draft a letter clearly labeled "Protest" with importer details, entry numbers, and grounds for challenge.
3. File electronically via ACE or mail to the port of entry.
4. Track status through ACE.

See the CBP protest procedures for submission guidance.

Claim Duty Drawback to Recover Up to 99% of Fees on Exports

You can recover up to 99% of duties and fees paid on goods that are later exported or destroyed. File electronically via ACE using CBP Form 7551 for the basic drawback claim and Form 7553 for supporting documentation.

Use a Prior Disclosure Statement (PSC) for unliquidated entries or a Protest (Form 19) for liquidated entries. This applies to manufacturing, unused merchandise, or rejected goods scenarios.

The process works like this:

1. Verify eligibility (e.g., exported within 5 years).
2. Prepare Forms 7551 and 7553 with proof of export or destruction.
3. Submit via ACE and monitor for approval.

Understand the 2026 CBP Tariff Refund Process

The 2026 CBP tariff refund process for IEEPA tariffs follows a four-step timeline via the ACE/CAPE system: claim submission, validation and recalculation, review and liquidation, and ACH refund. This handles potential refunds for importers, with the system 40-80% complete as of March 2026.

The steps are:

1. Claim Submission: File claims electronically in ACE/CAPE with entry data and tariff details.
2. Validation/Recalculation: CBP verifies and adjusts duties.
3. Review/Liquidation: Finalize reliquidation.
4. ACH Refund: Electronic payment upon approval (enrollment required).

Prepare by securing ACE access and ACH setup. Sources like Metro Global, Grassi Advisors, and The Hill confirm the structured rollout.

Choose the Right Path: Protest, Drawback, or ACH for Your Fee Complaint

Match your situation to the entry status and fee type. A Protest works for liquidated entries with errors, PSC for unliquidated ones, Duty Drawback for exports or destructions, and ACH enrollment for all electronic refunds (with waivers if needed). Tariff claims use the dedicated ACE/CAPE process. Enroll in ACH first for faster processing, then select the path that fits.
