Where your tariff refund comes from and who processes it
A tariff refund is money returned to you by U.S. Customs and Border Protection (CBP) when you overpaid duties on imported goods or when CBP determines the tariff rate applied to your shipment was incorrect. The refund does not come from a general government fund — it comes from the duties you or your company actually paid at the time of import.
CBP handles most tariff refunds through the Customs and Border Protection Refunds and Adjustments system. If you imported goods yourself, you file a refund claim. If a customs broker or freight forwarder brought in your goods, they typically file on your behalf, though you may need to authorize them to do so. The timeline from filing to receiving money usually runs 60 to 120 days, depending on the complexity of your case and CBP's current workload.
Some tariff refunds fall under special programs — for example, the Merchandise Processing Fee (MPF) refund program or claims related to specific trade disputes. The process and timeline can differ for each type, so identifying which kind of refund you are seeking is your first step.
Key Takeaways
- Tariff refunds are processed by U.S. Customs and Border Protection and must be requested through a formal claim; money does not return automatically.
- You need your entry number (the CBP document that shows what you imported and what you paid), your invoice, and proof of payment to file a claim.
- If a customs broker or freight forwarder handled your import, they can file the claim on your behalf, but you should confirm they have your written authorization.
- Refunds typically arrive 60 to 120 days after CBP receives your complete claim, though complex cases or high-value shipments may take longer.
- You can track your claim status through the CBP portal or by contacting the port of entry where your goods were processed.
Gathering the documents you need before filing
CBP will not process a refund claim without specific paperwork. Start by locating your entry number — this is a nine-digit code assigned by CBP when your shipment cleared customs. You can find it on your customs entry paperwork, your bill of lading, or your freight forwarder's invoice. Without this number, CBP cannot match your claim to the actual shipment.
Next, collect your commercial invoice (the document showing what you bought, the price, and the country of origin) and your proof of payment — usually a receipt or bank statement showing you paid the duties. If CBP charged you a Merchandise Processing Fee, you will need documentation of that charge as well. Keep copies of everything; CBP may ask you to resubmit if pages are unclear or missing.
If you used a customs broker or freight forwarder, ask them for a copy of your entry paperwork and the CBP receipt showing duties paid. Some brokers keep these records for only a limited time, so request them as soon as you know you need a refund. If your shipment arrived more than three years ago, you may still file a claim, but CBP's records become harder to locate the older the entry is.
Filing your claim through CBP or your customs broker
You have two main routes: file directly with CBP yourself, or have your customs broker or freight forwarder file on your behalf. Most importers use a broker because brokers know CBP's current procedures and can navigate the system faster, but you can file yourself if you prefer.
To file directly with CBP, contact the port of entry where your goods were processed. You can find the correct port by looking at your entry paperwork or by searching CBP's port directory on their website. Call the port's cargo facility and ask for the refunds department, or submit your claim in writing to the port's address. Include your entry number, a clear explanation of why you believe you are owed a refund (for example, "tariff rate was misclassified" or "duplicate duties were charged"), and copies of your supporting documents.
If your broker is filing, provide them with a written authorization stating that they may file a refund claim on your behalf. Give them all the documents listed above and ask them to confirm receipt. Ask them for a copy of the claim once they file it, and ask them to give you the claim number so you can track it yourself.
Understanding why CBP might deny or reduce your refund
CBP denies refund claims for several common reasons. The most frequent is that the tariff classification or rate applied to your goods was correct according to CBP's interpretation of the tariff schedule at the time of import. If CBP denies your claim on this basis, you have the right to appeal, though the appeal process is separate from the refund process and can take several months.
CBP may also reduce your refund if you filed the claim after the one-year deadline from the date of entry. While you can technically file up to three years after import, CBP may argue that the delay weakens your case or that records are incomplete. If you are filing late, include a written explanation of why the delay occurred.
Another reason for denial is incomplete documentation. If CBP cannot verify the entry number, the amount paid, or the goods themselves, they will ask you to resubmit. Respond to any CBP request for additional information within 30 days; if you do not, your claim may be closed.
Tracking your refund claim and following up
Once you file, CBP will send you a claim number. Write this down and keep it safe — you will need it to check status. You can track your claim through the CBP Automated Commercial Environment (ACE) portal if you have access, or by calling the port of entry directly and providing your claim number and entry number.
The typical timeline is 60 to 120 days from the date CBP receives your complete claim. However, if your claim involves a high-value shipment, a complex tariff question, or a dispute with CBP's original classification, the review may take longer. CBP will notify you by mail or email (depending on how you filed) once a decision is made.
If you have not heard back after 120 days, contact the port of entry again. Sometimes claims get delayed due to staffing or because CBP is waiting for additional information from you. A follow-up call can often speed things up. If CBP has lost your claim or cannot locate it, ask them to search their system by entry number.
What happens when CBP approves your refund
When CBP approves your claim, they will issue a refund authorization and process the money back to the account or method you used to pay the original duties. If you paid by check, CBP will mail you a check. If you paid by credit card or bank transfer, the refund goes back to that same source. This can take an additional 10 to 30 days after approval, depending on your bank or payment processor.
CBP will send you written notice of the approval, including the refund amount and the expected payment date. Keep this notice for your records. If you are a business, you may want to record the refund as income or a credit on your books, depending on your accounting method.
If the refund amount is less than you expected, review CBP's explanation carefully. They may have reduced the amount because they determined only part of your claim was valid, or because they found an error in the original duty calculation that reduced the refund owed. If you disagree, you can appeal within a set timeframe — CBP's notice will include the deadline and instructions.
Appealing a denial or partial refund
If CBP denies your claim or offers a refund smaller than you believe you are owed, you can file a protest with CBP's Office of International Trade. A protest is a formal objection to CBP's decision and must be filed within 180 days of the date CBP issued their decision. You do not need a lawyer, but the process is more formal than the initial refund claim.
To file a protest, write a letter to CBP explaining why you disagree with their decision. Include your entry number, claim number, copies of all supporting documents, and a clear statement of the amount you believe you are owed. Mail it to the port of entry or submit it through the ACE portal if you have access. CBP will acknowledge receipt and assign your protest a number.
The protest review process typically takes 60 to 180 days. If CBP upholds their denial, you have the option to pursue the matter further through the U.S. Court of International Trade, though this is expensive and usually only done for high-value claims. Many importers consult a customs attorney at this stage.
Frequently Asked Questions
Can I file a tariff refund claim if my customs broker handled the import?
Yes. Your broker can file the claim on your behalf if you give them written authorization. Ask them to provide you with a copy of the claim and the claim number so you can track it. If your broker is no longer in business or will not file, you can file the claim yourself using your entry number and the documents the broker gave you.
How far back can I go to file a tariff refund claim?
You can file a claim up to three years after the date of entry. However, CBP prefers claims filed within one year, and filing after one year may delay your refund or result in a denial if records are incomplete. The sooner you file, the better your chances of approval.
What if I paid duties but do not have my entry number?
Contact the port of entry where your goods arrived and provide them with your invoice, the date of import, and the shipper's name. CBP can search their records and locate your entry. You can also ask your freight forwarder or customs broker for a copy of the entry paperwork if you used one.
Will I owe taxes on the refund money I receive?
That depends on your situation and how you account for the original duty payment. If you deducted the duty as a business expense, the refund may be taxable income. Consult your accountant or tax advisor about how to report the refund on your tax return.
How long does it take to receive the actual money after CBP approves my claim?
After approval, expect 10 to 30 additional days for the money to reach your bank account or for a check to arrive by mail. The exact timeline depends on your bank and the payment method used. If you do not see the refund within 30 days of the approval date, contact CBP or your bank to confirm the payment was processed.
