A tariff refund is money the U.S. government returns to you when you pay import duties on goods that shouldn't have been taxed that way

When you import goods into the United States, U.S. Customs and Border Protection (CBP) collects tariffs—taxes on those imports—at the port of entry. Sometimes those tariffs are calculated wrong, applied to the wrong product category, or charged on goods that are actually exempt. A tariff refund is the government's repayment of those overcharged duties.

The refund doesn't come automatically. You have to request it through CBP's formal process, which requires documentation proving the tariff was incorrect. The money comes from the federal government, not from the importer or broker who collected it. Refunds typically take several months to process, and the amount depends on how much you actually paid in duties at the time of import.

This is different from a chargeback or dispute with a seller. You're not disputing whether you owe the tariff at all—you're saying the tariff amount or category was wrong under U.S. trade law.

Key Takeaways

  • A tariff refund is money returned by U.S. Customs when import duties were calculated incorrectly, applied to the wrong product classification, or charged on exempt goods.
  • You must file a formal claim with CBP within one year of the date the tariff was paid, and you need the original entry documents and proof of payment.
  • The refund process typically takes three to six months from the date CBP receives your complete claim, though complex cases can take longer.
  • You can file a claim yourself or work with a customs broker, though brokers charge a fee for handling the paperwork and follow-up.
  • CBP will deny your claim if you miss the one-year important date, fail to provide required documents, or cannot show the tariff was actually incorrect under U.S. law.

When tariffs get refunded

CBP refunds tariffs in specific situations. The most common is tariff misclassification—your goods were put in the wrong product category, which carries a different duty rate. For example, a fabric blend might be classified as synthetic when it should be classified as cotton, resulting in a lower tariff. Another reason is that the goods were actually duty-free or exempt under a trade agreement or statute, but CBP charged you anyway. A third scenario is that you paid a tariff on goods that were later found to be defective or damaged in a way that should have reduced the duty owed.

You can also receive a refund if CBP charged you based on an incorrect country of origin. Different countries have different tariff rates under U.S. trade law, so if your goods came from a country with lower duties but were marked as coming from a higher-duty country, you overpaid.

Refunds do not cover tariffs that were correct at the time they were charged, even if the law changed later. If Congress raised or lowered tariff rates after your import, you cannot go back and claim a refund based on the new rate.

The documents you need to file a claim

CBP requires specific paperwork to process a refund claim. You must provide the entry number (the unique identifier CBP assigned when your goods arrived), the date the tariff was paid, and the amount paid. You can find this information on your entry summary or the receipt from CBP.

You also need proof of what you imported and why the tariff was wrong. This might be a commercial invoice, packing list, bill of lading, or product specification sheet. If you're claiming misclassification, include documentation showing what the goods actually are—lab reports, manufacturer certifications, or informed opinions can help. If you're claiming the goods were exempt, include the statute or trade agreement that supports that claim.

Finally, you need proof you actually paid the tariff. This is usually your CBP receipt or payment confirmation from the broker who handled the import. If a customs broker paid the tariff on your behalf, you may need a letter from them confirming the amount and date.

How to file a tariff refund claim with CBP

You file a claim using CBP Form 19, also called a "Protest." This is the official form for disputing CBP decisions, including tariff charges. You can read it from the CBP website or request it from your local CBP office. The form asks for your entry number, the reason you believe the tariff was wrong, and the refund amount you're requesting.

You must file within one year of the date the tariff was paid. This important date is strict—CBP will not extend it. If you miss it, your claim is denied automatically. The one-year clock starts from the date on your CBP receipt, not the date you imported the goods.

Mail the completed form and all supporting documents to the CBP office that handled your entry. You can find the correct address on your entry summary. Keep copies of everything you send. CBP will send you a receipt number when they receive your claim, and you can use that number to track the status online through the CBP website.

What happens after you file

After CBP receives your claim, they assign it to a liquidation specialist who reviews your documents and the original entry. This review typically takes one to two months. The specialist may request additional information or documentation if they need clarification. You should respond to any requests within 30 days, or your claim may be delayed or denied.

Once the review is complete, CBP issues a decision. If they approve your claim, they process the refund through the U.S. Treasury. The refund is usually deposited to the account or method you used to pay the original tariff—if you paid by check, you receive a check back; if you paid electronically, the money goes back to that account. This final step typically takes one to two months after approval.

If CBP denies your claim, they send you a written explanation. You can appeal the denial by filing a protest of the denial with CBP's Office of Trade within 180 days. This is a second review, and it requires additional documentation or legal argument about why CBP's decision was wrong.

Working with a customs broker versus filing yourself

You can file a tariff refund claim on your own, but many importers use a customs broker to handle it. A broker knows CBP's requirements, can gather the right documents, and handles the back-and-forth with CBP if they request more information. This reduces the chance your claim gets denied for missing paperwork.

The trade-off is cost. Brokers typically charge a flat fee (usually $500 to $2,000 depending on complexity) or an hourly rate to prepare and file your claim. If your refund is small—under $1,000—paying a broker may not make financial sense. If your refund is large or the misclassification is complex, a broker's fee is often worth it because they increase the chance of approval and speed up the process.

If you file yourself, you need to be organized and thorough. Missing a single required document can delay your claim by weeks. You also need to understand the tariff code and trade law well enough to explain why the original classification was wrong—CBP will not accept vague arguments.

Timeline and realistic expectations

A straightforward tariff refund claim—one with clear documentation and an obvious error—typically takes three to four months from filing to refund. More complex claims, especially those involving product classification disputes or trade agreement interpretation, can take six months or longer.

The timeline breaks down roughly like this: CBP takes one to two months to review your claim and request any additional documents. You take up to 30 days to respond. CBP takes another one to two months to issue a decision. If approved, the Treasury takes one to two months to process the refund. If denied, you can appeal, which adds another three to six months.

Do not expect a refund within weeks. CBP processes thousands of claims, and they work in the order they receive them. If you need the money urgently, a tariff refund is not a reliable source. Plan for the money to arrive months after you file, and budget accordingly.

Frequently Asked Questions

Can I file a tariff refund claim if I don't have the original entry number?

You can request it from CBP or your customs broker. The entry number is on your CBP receipt or entry summary. If you cannot find it, contact the CBP office at the port where your goods arrived with your company name, the approximate import date, and a description of the goods. They can look it up for you, though this may take a few weeks.

What if CBP says the tariff was correct and denies my claim?

You can file a protest of the denial with CBP's Office of Trade within 180 days of the denial letter. This requires submitting additional evidence or a legal argument about why CBP's interpretation of the tariff code was wrong. Many importers hire a trade attorney for this step because it involves complex tariff law.

Do I get interest on my refund if it takes a long time?

No. CBP does not pay interest on tariff refunds, even if the claim takes six months or longer to process. The refund is the tariff amount only, not the tariff plus interest.

Can I file a claim for tariffs paid more than a year ago?

No. The one-year important date is absolute. CBP will not accept claims filed after one year from the date the tariff was paid, regardless of the reason for the delay.

What if my customs broker paid the tariff but I want the refund?

You can still file the claim, but you need written permission from the broker or proof that you reimbursed them for the tariff. CBP will refund the money to whoever paid the tariff originally. If the broker paid it, the refund goes to them unless you have documentation showing the tariff was your expense and you paid the broker back.
