The refund amount depends on what you paid and which tariffs were reduced or removed

A tariff refund returns the duties you paid on imported goods when those tariffs are lowered, suspended, or eliminated. The amount you receive is the difference between what you originally paid and what the new tariff rate requires. If tariffs drop from 25% to 10%, you get back 15% of the value of those goods. If tariffs are removed entirely, you get back 100% of what you paid.

The actual dollar amount varies widely depending on three things: the original cost of the goods you imported, the tariff rate that applied when you bought them, and the new rate (or zero rate) that now applies. A small business importing $50,000 worth of steel might receive a few thousand dollars back. A large importer moving millions in goods could receive tens of thousands or more.

You do not receive a refund automatically. You must file a claim with U.S. Customs and Border Protection (CBP) within the time window allowed for your type of goods, usually one to three years after the tariff change takes effect.

Key Takeaways

  • Your refund equals the tariff rate reduction multiplied by the total value of goods you imported under the old rate.
  • Different product categories have different claim deadlines, ranging from one to three years after the tariff change.
  • You must have documentation proving the original tariff paid, the date of import, and the goods themselves.
  • CBP processes refund claims through the Merchandise Processing Fee refund system or the Trade Adjustment Assistance program, depending on the tariff type.

How CBP calculates the refund amount

CBP uses a straightforward formula: refund amount = (old tariff rate minus new tariff rate) × value of goods. If you imported $100,000 worth of machinery at a 20% tariff rate, you paid $20,000 in duties. If the rate drops to 5%, the new duty is $5,000. Your refund is $15,000.

The "value of goods" is the dutiable value recorded on your entry documents at the time of import, not the price you sold them for later. This is the amount CBP used to calculate your original duty payment. You can find this on your entry summary (CBP Form 3461) or your commercial invoice.

If you imported goods in multiple shipments over time, each shipment is calculated separately based on when it entered the country and what rate applied on that date. A tariff reduction that took effect on March 1 does not apply to goods you imported on February 28, even if you file your claim months later.

Tariff suspensions versus permanent reductions

A tariff suspension temporarily removes duties for a specific product, usually for one to three years. When the suspension expires, the old rate returns unless Congress extends it. If you imported goods during a suspension period and the tariff came back, you do not owe additional money—you keep the benefit of the suspension. If you imported during the suspension and file a refund claim after the suspension ends, your refund is based on the zero rate that applied when you imported.

A permanent tariff reduction lowers the rate indefinitely. Refunds for permanent reductions are typically larger because the rate change is expected to last. However, permanent reductions can still be reversed by Congress or through trade negotiations, which would affect future imports but not refunds already issued.

Trade agreement tariff changes (such as those under USMCA or other bilateral agreements) are treated as permanent reductions for refund purposes, though the agreement itself can be renegotiated or terminated.

What documentation you need to claim your refund

CBP requires proof of the original tariff paid and the goods involved. Gather your entry summary (CBP Form 3461 or 3461 ALT), commercial invoice, packing list, and bill of lading or air waybill. These documents show the date of import, the product description, the declared value, and the duty amount paid.

You will also need to show which tariff rate applied on the date you imported. CBP publishes the Harmonized Tariff Schedule (HTS) with effective dates for each rate change. If you imported on June 15 and the new rate took effect on June 20, the old rate applies to your shipment. You can search the HTS on the CBP website or through the International Trade Commission database.

Keep copies of any correspondence with CBP, your customs broker, or the importer of record. If CBP requests additional information, respond within the timeframe they provide—delays can result in denial of your claim.

Claim deadlines and how they affect your refund

The deadline to file a tariff refund claim is typically one to three years from the date the tariff change took effect, depending on the product category and the type of tariff change. Steel and aluminum tariff suspensions, for example, often have a one-year window. Other product suspensions may allow three years. Permanent rate reductions sometimes have longer windows or no hard deadline.

Missing the deadline means you lose the refund entirely. CBP does not extend deadlines for late filing, and there is no appeal process if you miss the window. If you are unsure of the deadline for your specific goods, contact your customs broker or call the CBP Tariff Classification and Trade Agreements office at 877-CBP-5511.

The clock starts on the effective date of the tariff change, not the date you imported the goods. If you imported goods in 2022 under a 25% tariff and the rate dropped to 10% in 2024, your one-year window to claim opens in 2024, not 2022.

Where to file your refund claim

File your claim with the CBP port of entry where your goods were imported. You can submit by mail, in person, or through the Automated Commercial Environment (ACE) system if your company has ACE access. Include a cover letter stating the tariff rate reduction, the entry numbers of the shipments involved, the total refund amount you are requesting, and the calculation showing how you arrived at that amount.

CBP typically acknowledges receipt within 30 days and issues a decision within 90 to 180 days, though complex claims can take longer. You will receive written notice of approval or denial. If approved, the refund is issued as a credit to your CBP account or as a check, depending on your preference and the port's procedures.

If CBP denies your claim, you have the right to file a protest within 90 days of the denial notice. A protest is a formal request for reconsideration and requires detailed documentation of why you believe CBP's decision was wrong.

Special cases: exclusions and limited refunds

Some tariff changes do not allow refunds. Tariffs imposed as retaliation or national security measures sometimes include language stating that no refunds will be issued for goods imported before the change. Read the Federal Register notice announcing the tariff change to see if refunds are excluded.

If you re-exported the goods (shipped them out of the United States) before the tariff change, you may still be able to claim a refund, but the process is more complex. You must prove the goods left the country and provide export documentation. Contact CBP before filing to confirm you are may be able to access.

Goods that were damaged, destroyed, or lost in transit may also have limited refund options. If the goods never reached their final destination or were a total loss, CBP may reduce or deny the refund because the tariff duty was tied to goods that no longer exist in commerce.

Frequently Asked Questions

Can I get a refund if I already sold the goods?

Yes. The refund is based on the tariff you paid at import, not on what happened to the goods afterward. You can claim a refund whether the goods are still in inventory, have been sold, or have been used in manufacturing. The refund goes to the importer of record or the company that paid the duty.

What if my customs broker paid the tariff on my behalf?

The refund is issued to the importer of record listed on the entry documents, which is usually your company. If your broker paid the duty as an agent, you still file the claim and receive the refund. Coordinate with your broker to ensure they have the entry details you need and that you both understand who will file the claim.

Do I have to pay taxes on the refund I receive?

Tariff refunds are generally treated as a recovery of a business expense, not as taxable income. Consult your tax professional or accountant about how to report the refund on your tax return, as treatment can vary depending on your business structure and accounting method.

What happens if CBP says I owe money instead of getting a refund?

This can occur if CBP recalculates the original duty and finds you underpaid. If this happens, you will receive a bill for the difference. You have the right to protest the bill within 90 days if you believe the calculation is wrong. Do not ignore the bill—CBP can place a hold on future imports or refer the debt to a collection agency.

How long does it take to receive the refund after CBP approves my claim?

Processing time varies by port and claim complexity. Most refunds are issued within 30 to 60 days of approval, but some ports take longer. You can contact the port of entry to ask about the status of your approved claim. Refunds are typically issued as a credit to your CBP account or as a check mailed to your address on file.
