The refund amount depends on what you paid and which tariff program you're in
A tariff refund is not a fixed dollar amount. It is the difference between what you paid on imported goods and what you should have paid under a different tariff rate or after a tariff was removed. The actual number depends on three things: the original tariff rate you paid, the new rate (or zero, if the tariff was eliminated), the value of the goods, and how much you imported.
If you paid a 25% tariff on $10,000 worth of steel and that tariff was later reduced to 15%, your refund would be 10% of $10,000—$1,000. But if the tariff was eliminated entirely, your refund would be 25% of $10,000—$2,500. The calculation is straightforward once you know the rate change. The harder part is proving what you actually paid and when.
Key Takeaways
- Refund amounts are calculated by multiplying the tariff rate difference by the declared value of the goods you imported.
- You must have paid the original tariff through U.S. Customs and Border Protection (CBP) to be may be able to access for a refund on that shipment.
- The CBP Entry/when ready Delivery form (Form 3461) and your commercial invoice are the documents that prove both the tariff rate paid and the goods' value.
- Refund requests must be filed within one year of the tariff change or rate adjustment that created the difference, though some programs have longer windows.
- The refund is issued to the importer of record—the person or company whose name appears on the CBP entry documents—not necessarily the business owner.
What information you need to calculate your own refund
Start with your CBP entry documents. The Entry/when ready Delivery form (Form 3461) shows the tariff rate applied to each line item and the declared value of those goods. This is the official record of what you paid. If you imported goods under multiple shipments or on different dates, each entry has its own tariff calculation.
Next, find the tariff rate that applies now—or the rate that applied on the date the change took effect. The U.S. International Trade Commission (USITC) publishes the Harmonized Tariff Schedule, which lists every product code and its current rate. If a tariff was reduced or removed, the schedule shows the effective date of that change. The difference between the rate you paid and the current (or new) rate is your refund percentage.
Multiply that percentage by the declared value on your entry form. If you imported 500 units at $20 each ($10,000 total) and paid 20% tariff, you paid $2,000 in tariffs. If the rate dropped to 10%, your refund is 10% of $10,000—$1,000. If the tariff was eliminated, your refund is the full $2,000.
How the importer of record affects your refund claim
The refund goes to whoever is listed as the importer of record on the CBP entry documents, not to the business owner, the freight forwarder, or the person who paid the tariff. This matters because if you hired a customs broker or freight forwarder to handle the import, they may be listed as the importer of record instead of you.
Before you file a refund request, check your Form 3461 to see whose name appears in the importer field. If it is not your name or your company name, you will need written authorization from the actual importer of record to file on their behalf, or they must file the claim themselves. The CBP will not issue a refund to anyone else.
If your broker or forwarder is the importer of record, contact them and ask them to file the refund claim. Many will do this as part of their service, though some charge a fee. If they refuse or are no longer in business, you can request that the CBP transfer the importer of record designation to you, though this requires documentation and takes additional time.
Refund amounts for goods still in inventory versus goods already sold
The refund calculation is the same whether the goods are sitting in your warehouse or already sold to customers. What changes is whether you keep the refund or pass it to the buyer. If you sold the goods at a price that included the tariff cost, the refund is yours to keep. If you sold them at a price that assumed a lower tariff, you may have a contractual obligation to share the refund with the buyer.
From the CBP's perspective, the refund is based only on the tariff paid at the time of import. The agency does not track what happened to the goods after they entered the country. You file the claim, provide the entry documents, and receive the refund. Any agreement about how to split that refund with a buyer is a private matter between you and them.
When tariff refunds are partial rather than full
A partial refund happens when only some of the goods on an entry may have access to for the rate reduction or elimination. For example, if you imported both steel and aluminum on the same entry, and only the steel tariff was reduced, you would receive a refund only on the steel portion. The aluminum tariff remains unchanged.
This is common when tariff changes explore to specific product codes rather than entire categories. The CBP entry form breaks down the tariff by line item (each product code), so the refund calculation is done line by line. You will see the full refund amount for may have access to items and zero for non-may have access to items.
Some entries also have mixed tariff rates because goods were classified under different chapters of the Harmonized Tariff Schedule. If a reclassification occurs—meaning the CBP or a court determined the goods should have been classified differently—only the reclassified items receive a refund. The rest of the entry is unaffected.
How interest and penalties affect the final refund amount
If you overpaid tariffs and the CBP agrees you are owed a refund, you may also receive interest on that amount. The interest rate is set by the U.S. Department of the Treasury and changes quarterly. Interest accrues from the date you paid the tariff until the date the CBP issues the refund. For a refund filed one year after payment, interest could add 5 to 8 percent to the refund amount, depending on the quarter.
Penalties reduce the refund. If the CBP determines that you misclassified goods, undervalued them, or provided false information on your entry documents, they may deny the refund entirely or reduce it by the amount of the penalty. This is why accurate documentation at the time of import is critical. If you discover an error after the fact, some programs allow you to file a corrected entry (called a "protest" or "administrative review") before filing a refund claim, which can protect you from penalties.
Refund timelines and when you receive the money
The CBP does not issue refunds when ready. After you file a claim with supporting documents, the agency reviews the entry, verifies the tariff rate and goods value, and determines whether you are owed money. This review typically takes 30 to 90 days for straightforward cases. Complex cases—those involving classification disputes or value disagreements—can take six months or longer.
Once the CBP approves the refund, the money is issued as a credit to your CBP account or as a check, depending on how you filed and what you requested. If you have an active CBP account (used for regular imports), the refund is usually applied as a credit that you can use toward future tariff payments. If you request a check, it takes an additional two to four weeks to arrive after approval.
The one-year important date to file a refund claim starts from the date the tariff was paid, not the date it was changed. If you paid a tariff on January 15, 2023, you have until January 15, 2024, to file a refund claim for that shipment, even if the tariff rate changed in March 2023. Missing this important date means the CBP will not consider your claim.
Frequently Asked Questions
Can I get a refund if I passed the tariff cost to my customer?
Yes. The CBP refund is based on what you paid at import, not on what you charged your customer. If you included the tariff in the price you sold the goods for, the refund belongs to you. If you have a contract requiring you to share tariff refunds with the buyer, that is a separate agreement between you and them.
What if the CBP and I disagree on the goods' value or classification?
You can file a protest with the CBP within 180 days of the entry date, asking them to reconsider the value or classification. If the protest is denied, you can appeal to the U.S. Court of International Trade. Only after the classification or value is officially changed can you file a refund claim for the difference in tariffs owed.
Do I get interest on my refund if it takes a long time?
Yes. The CBP pays interest on approved refunds from the date you paid the tariff until the date the refund is issued. The interest rate is set by the Treasury Department and changes quarterly. For refunds approved after a long review, interest can add several hundred dollars to the refund amount.
What if my freight forwarder is the importer of record and they have gone out of business?
You can request that the CBP transfer the importer of record designation to you, though this requires proof that you are the actual owner of the goods and documentation of the forwarder's closure. Contact the CBP port where the goods were entered and ask for a Form 3461 amendment. This process takes several weeks.
Can I file a refund claim for goods I imported five years ago?
No. The CBP has a one-year important date from the date you paid the tariff. If you paid the tariff five years ago, that important date has passed and the CBP will not consider a refund claim. The only exception is if a court order or a specific tariff suspension program extends the important date, which is rare.
