The basic rule: you paid a tariff on goods you imported, and the tariff rate changed or was removed

A tariff refund is money returned to you because you paid a duty on imported goods that you should not have paid, or should have paid less on. This happens in three main situations: the tariff rate dropped after you paid, the product was reclassified into a lower-duty category, or the tariff was eliminated entirely.

The U.S. Customs and Border Protection (CBP) does not automatically send refunds. You have to request one, and you have to do it within a specific time window. The window is normally one year from the date you paid the duty, though some cases allow longer if you can show CBP made an error in how they classified your goods.

You do not need to be a large importer or a customs broker to request a refund. Any person or business that paid a tariff on goods they brought into the United States can file. The goods can be for your own use, for resale, or for manufacturing.

Key Takeaways

  • You can request a refund if the tariff rate on your goods dropped, the product was misclassified, or the tariff was removed after you paid duty.
  • You must file your refund request within one year of paying the tariff, though CBP errors can extend this window.
  • CBP requires the entry number from your customs declaration, the amount of duty paid, and proof of the rate change or misclassification.
  • Refunds are processed by the port of entry where your goods cleared customs, not by a central office.
  • If CBP denies your request, you can file a protest within two years of the denial decision.

What counts as a tariff rate change that triggers a refund

A rate change means Congress or the President changed the duty percentage on a specific product code. This happens through new trade agreements, tariff adjustments, or removal of existing tariffs. For example, if you paid 25% duty on steel imports in 2022, and the rate dropped to 15% in 2023, goods you imported under the old rate may be refundable.

The timing matters. You can only claim a refund on goods you imported and paid duty on after the old rate was in effect. If you imported goods before the rate changed, you paid the correct duty at that time and have no refund claim. If you imported after the new rate took effect, you should have paid the new rate—if you paid the old rate by mistake, that is a different type of claim.

Rate changes are published in the Federal Register and on the CBP website. You can search by product code or by the date the change took effect. If you are unsure whether your goods were affected, the CBP Tariff Information Center lets you look up the current rate and see historical rates for comparison.

Misclassification: when CBP put your goods in the wrong tariff category

Every imported product has a tariff classification code—a 10-digit number that determines which duty rate applies. If CBP classified your goods incorrectly when they cleared customs, you may have paid the wrong duty amount. A lower classification code means lower duty; a higher one means you overpaid.

Misclassification claims are common with products that sit on the border between categories. A fabric blend might be classified as synthetic (higher duty) when it should be natural fiber (lower duty). A tool might be classified as a finished product when it is a component. You need to show CBP that the correct classification exists and that your goods fit it.

To prove misclassification, you typically need the product itself (or detailed photos and specifications), the entry documents from customs, and evidence of what the correct classification should be. This can be a technical data sheet, a letter from the manufacturer, or a ruling from CBP on an identical or similar product. CBP has issued thousands of binding rulings on specific products—if one covers your goods, that is strong evidence.

The one-year filing window and how to extend it

You have one year from the date you paid the tariff to file a refund request with CBP. The payment date is on your entry documents—the form CBP gave you when your goods cleared customs. If you miss this important date, your claim is denied and you cannot recover the money.

There is one exception: if CBP made an error in administering the tariff law—for example, they misclassified your goods and you can show they should have known better—you may be able to file up to two years after payment. This is harder to prove and requires evidence that CBP's mistake was clear or that you relied on CBP guidance that turned out to be wrong.

The clock starts on the payment date, not the date you filed your entry or the date your goods arrived. If you imported goods on January 15 and paid duty on January 20, your one-year window closes on January 20 of the following year. Keep your entry documents and payment records in a safe place so you know exactly when the important date is.

Documents you need to file a refund request

CBP requires specific paperwork to process a refund claim. Start with your entry number—a unique identifier assigned when your goods cleared customs. This is on your entry summary form or your customs broker's paperwork. You also need the exact amount of duty you paid and the date you paid it.

Next, you need evidence of why you are may have access to to a refund. For a rate change, this is the Federal Register notice or CBP announcement showing the new rate and the effective date. For misclassification, this is the product specifications, photos, technical data, or a CBP ruling showing the correct classification. For a tariff elimination, this is the notice that the tariff was removed.

Finally, you need a written statement explaining your claim. This does not have to be long, but it should be clear: state the entry number, the amount of duty paid, the reason for the refund (rate change, misclassification, or elimination), and the correct duty amount or rate that should have applied. If you are working with a customs broker or trade attorney, they can prepare this for you.

Where to send your refund request and what happens next

You file your refund request with the CBP port of entry where your goods cleared customs. This is not a central office—each port has its own refunds unit. Your entry documents show which port processed your shipment. You can find contact information for that port on the CBP website under "Ports of Entry."

Mail your request to the port's refunds office or, at some ports, submit it through the Automated Commercial Environment (ACE) system if you have access. Include copies of all documents—do not send originals. Keep copies for yourself and consider sending by certified mail so you have proof of delivery.

CBP typically responds within 30 to 90 days, though complex cases take longer. They will either approve your refund, deny it, or ask for more information. If approved, the refund is issued as a check or, if you have a CBP account, as a credit to your account. If denied, you receive a written explanation of why.

What to do if CBP denies your refund request

A denial is not the end. You can file a protest with CBP within two years of the denial decision. A protest is a formal objection that asks CBP to reconsider. You file it with the same port that denied your claim, and you must include new evidence or a new legal argument—straightforward restating your original claim will not work.

If CBP denies your protest, you can appeal to the U.S. Court of International Trade, which handles tariff disputes. This requires an attorney and is expensive, so most small importers do not pursue it. However, if the refund amount is large, it may be worth the cost.

Before you file a protest, consider whether you have new evidence or a stronger legal argument than you presented the first time. If you do not, the protest is unlikely to succeed. If you are unsure, a customs attorney can review your case and advise whether a protest is worth filing.

Frequently Asked Questions

Do I need a customs broker to file a refund request?

No. You can file on your own if you have your entry documents and can gather the supporting evidence. A customs broker or trade attorney can help, especially if your claim is complex or involves misclassification, but it is not required. Many small importers file successfully without professional help.

Can I get a refund if I imported goods before a tariff was announced but after it took effect?

No. The refund applies only to goods you imported and paid duty on while the old rate was in effect. Once the new rate takes effect, you pay the new rate going forward. If you imported after the new rate was announced but before it took effect, you paid the correct rate at that time.

What if my customs broker paid the tariff and I reimbursed them?

You can still file a refund request. The refund goes to whoever paid CBP—usually your broker. Ask your broker to file the claim on your behalf, or ask them to transfer the refund to you once it is approved. Get this in writing so there is no dispute later.

How long does it take to get the refund money?

CBP typically processes refunds within 30 to 90 days of approval, though some take longer. Once approved, the refund is issued as a check mailed to your address or as a credit to your CBP account. Checks can take an additional one to two weeks to arrive depending on mail speed.

Can I claim a refund on goods I imported more than a year ago?

Only if CBP made an error in administering the tariff law and you can prove it. The standard one-year window is firm for most claims. If you believe CBP made a clear error, consult a customs attorney before filing—they can assess whether you have grounds for the extended important date.
