What a tariff refund is

A tariff refund is money returned to you when you have overpaid duties on goods you imported into the United States. When U.S. Customs and Border Protection (CBP) collects tariffs at the border, they sometimes collect more than the law requires, or they collect on goods that later turn out to be exempt. The difference comes back to you as a refund.

Tariff refunds are not the same as tariff relief programs or trade adjustments. A refund is specifically money you already paid that should not have been collected. The refund goes to whoever paid the tariff at the time of import — usually the importer of record, the customs broker who handled the shipment, or the business that owns the goods.

You cannot get a tariff refund without filing a formal claim with CBP. The process requires documentation of what you paid, proof of the overpayment or exemption, and often a reason why the tariff should not have applied. Refunds can take months to process, and CBP denies many claims that lack the right paperwork.

Key Takeaways

  • A tariff refund is money returned when CBP collected more duty than required or collected duty on goods that should have been exempt.
  • You must file a formal claim with CBP within three years of the date the tariff was paid, or you lose the right to the refund.
  • The claim requires your entry number, the amount paid, proof of overpayment or exemption, and supporting documents like invoices or classification rulings.
  • CBP processes refund claims through its Automated Commercial Environment (ACE) system, and processing times range from several months to over a year.
  • If CBP denies your claim, you can file a protest or pursue a lawsuit in the U.S. Court of International Trade, but both require meeting strict deadlines and procedural rules.

When you are owed a tariff refund

You may be owed a refund if CBP assessed tariff duties on your shipment but the goods were actually exempt, misclassified, or subject to a lower rate than what was charged. Common reasons include goods that may have access to for duty-free treatment under trade agreements, items that were incorrectly classified into a higher-duty category, or shipments where the tariff rate changed between the time of entry and the time of liquidation.

Overpayment can also happen when you paid tariffs on goods that were later returned to the supplier, destroyed, or exported. If the goods never entered U.S. commerce, or if you paid tariffs and then the goods were re-exported, CBP should refund the duties. You are also may have access to to a refund if a court or CBP ruling later determined that the tariff classification or rate was wrong at the time you paid.

Tariff refunds are different from tariff waivers or exclusions. A waiver or exclusion prevents you from paying tariffs in the first place. A refund returns money you already paid. If you paid tariffs and later learned the goods should have been exempt, you need to file for a refund, not a waiver.

How to file a tariff refund claim with CBP

To file a tariff refund claim, you must submit a written request to CBP's port of entry where your goods were imported. The claim must include your entry number (the unique identifier CBP assigned to your shipment), the date the tariff was paid, the amount of the overpayment, and a clear explanation of why you believe the tariff should not have been collected or was assessed at the wrong rate.

You will need to gather supporting documents before you file. These typically include the commercial invoice, the bill of lading, the entry summary (CBP Form 7501), any customs broker documents, proof of payment, and evidence of the correct tariff classification or rate. If your claim is based on a court decision or a CBP ruling, include a copy of that decision or ruling. If the goods were returned or re-exported, provide shipping records or export documentation.

CBP prefers claims filed through its Automated Commercial Environment (ACE) system, which is the official electronic customs clearance platform. You can also file by mail or in person at the port where the entry was processed. If you use a customs broker, they can file the claim on your behalf, but you remain responsible for providing all required documents and for the accuracy of the claim.

The three-year deadline for tariff refund claims

You have three years from the date the tariff was paid to file a refund claim with CBP. This deadline is firm — if you miss it, CBP will deny your claim and you will have no recourse. The three-year period starts on the date CBP collected the duty, not the date you received the goods or the date you discovered the overpayment.

If you are unsure of the exact date the tariff was paid, check your entry summary or customs broker records. CBP's ACE system shows the liquidation date, which is when the tariff became final and the three-year clock started. If you are close to the deadline, file your claim immediately — waiting until the last day creates risk if there are delays in submission or if CBP requests additional information.

The three-year rule applies to all tariff refund claims, regardless of the reason for the overpayment. There is no exception for claims based on new court rulings or changes in tariff law. If a court decision comes down after your three-year window has closed, you cannot use that decision to support a new refund claim for the same goods.

How long tariff refunds take and how you receive the money

CBP does not publish standard processing times for tariff refund claims. Most claims take between three and twelve months to process, but complex claims or those requiring additional investigation can take longer. CBP will contact you if they need more information, and the clock does not stop while you are gathering documents — you still have a deadline to respond, usually thirty days.

Once CBP approves your claim, the refund is issued as a credit to your customs account or as a direct payment, depending on how you originally paid the tariff. If you paid by check or wire transfer, CBP will refund you by the same method. If you paid through a customs broker's account, the credit may go to the broker's account first, and the broker will then pay you. Ask your broker how they handle refunds before you file.

You can track the status of your claim by contacting the port of entry where you filed it or by checking ACE if you have access. CBP does not send automatic status updates, so you may need to follow up periodically. If your claim has been pending for more than a year with no response, contact the port's tariff and duty section directly.

What happens if CBP denies your tariff refund claim

If CBP denies your claim, they will send you a written decision explaining the reason. Common reasons for denial include missing documentation, failure to meet the three-year deadline, incorrect entry number, or CBP's information that the tariff was correctly assessed under the law. The denial letter will tell you what documents were missing or what CBP believes was wrong with your claim.

You have two options after a denial. You can file a protest with CBP within ninety days of the denial, arguing that CBP made an error in fact or law. A protest is a formal written challenge that requires you to cite the specific tariff code, trade agreement, or court ruling that supports your position. CBP will review the protest, but they often uphold their original decision.

If the protest is also denied, you can file a lawsuit in the U.S. Court of International Trade (CIT). The CIT is a specialized federal court that handles tariff and trade disputes. Lawsuits in the CIT are expensive and require an attorney familiar with customs law. You must file within two years of the date CBP denied your protest. Most importers pursue this option only when the refund amount is large enough to justify the legal cost.

Working with a customs broker on tariff refunds

A customs broker can file a tariff refund claim on your behalf and handle communication with CBP. Brokers are licensed by CBP and have direct access to the ACE system, which can speed up the filing process. If you imported goods through a broker, they already have your entry documents and may be able to identify overpayments you did not notice.

Customs brokers typically charge a flat fee or hourly rate to file a refund claim. The fee depends on the complexity of the claim and the amount of research required. If your claim is straightforward — for example, goods that were clearly misclassified — the broker's fee may be modest. If the claim requires tariff research, correspondence with CBP, or gathering documents from multiple sources, the cost will be higher.

Before you hire a broker, ask whether they charge a fee regardless of whether the claim is approved, or whether they work on contingency (taking a percentage of the refund if approved). Most brokers charge upfront, but some will negotiate a contingency arrangement for larger claims. Get the fee agreement in writing before the broker begins work.

Frequently Asked Questions

Can I file a tariff refund claim if I no longer have the original entry documents?

CBP can look up your entry in ACE using your entry number, so you do not need the original documents to start a claim. However, you will need supporting evidence of the overpayment — such as a commercial invoice, proof of payment, or a tariff ruling. If you cannot locate these documents, ask your customs broker or the supplier to provide copies. CBP may deny the claim if you cannot provide enough evidence to support your position.

What is the difference between a tariff refund and a tariff exclusion?

A tariff exclusion prevents you from paying tariffs on certain goods in the first place. An exclusion is usually granted by Congress or the President for a limited time and applies to specific products from specific countries. A tariff refund returns money you already paid. If you paid tariffs before an exclusion was granted, you may be able to file a refund claim for the duties you paid during the exclusion period.

Do I need a lawyer to file a tariff refund claim?

You do not need a lawyer to file a simple refund claim with CBP. A customs broker can handle the filing for you. However, if CBP denies your claim and you want to file a protest or lawsuit, an attorney who specializes in customs law can significantly improve your chances. The cost of an attorney is usually justified only if the refund amount is substantial.

Can I file a tariff refund claim for goods I imported years ago?

Only if you are within three years of the date the tariff was paid. If more than three years have passed, CBP will deny your claim. The three-year period is absolute — there are no exceptions, even if you did not know about the overpayment until recently.

What happens to my refund if my company goes out of business?

If your company is dissolved or bankrupt, CBP will still process a refund claim if it was filed before the deadline. The refund will be issued to the company's account or to whoever is authorized to receive it on behalf of the company. If the company is in bankruptcy, the refund may go to the bankruptcy trustee. Consult with your bankruptcy attorney about how to handle pending refund claims.
