If you import goods into the United States and later ship some of them back out of the country, you are probably leaving money with U.S. Customs that you are entitled to get back. The program is called duty drawback, it has existed since 1789, and it refunds up to 99% of the duties, taxes and fees paid on imported merchandise that is subsequently exported or destroyed.
Almost nobody uses it. Industry estimates have long suggested that the large majority of recoverable drawback is never claimed — not because companies are ineligible, but because the paperwork looks harder than the refund looks big. In a tariff environment where import costs have climbed sharply, that calculation has changed.
This guide covers what actually qualifies in 2026, which tariffs you can and cannot claim back, what filing costs, and the volume at which it stops being worth the effort.
What duty drawback actually is
Duty drawback is a refund mechanism, not a loophole. The logic is straightforward: the United States collects duty on goods entering the country for domestic consumption. If those goods do not stay — because they are re-exported, or destroyed under customs supervision — the duty was collected on a transaction that never happened as assumed. Drawback returns it.
Three categories matter to most shippers:
- Unused merchandise drawback — you imported goods, they sat in U.S. inventory, and you later exported them in the same condition. This is the most common case for ecommerce and distribution businesses.
- Manufacturing drawback — you imported components, used them to build something in the U.S., and exported the finished product.
- Rejected merchandise drawback — goods arrived defective, not as ordered, or non-conforming, and were exported or destroyed.
One important limitation: substitution drawback, which lets you match an export to a commercially interchangeable import rather than the exact same unit, is not available for exports to Canada, Mexico or Chile. Direct identification drawback still is.
Which 2026 tariffs you can claim back — and which you cannot
This is where most claims fail before they start. Not every charge on your entry summary is recoverable, and the list has shifted with recent trade policy.
| Charge type | Drawback eligible? | Notes |
|---|---|---|
| Standard MFN / normal trade relations duty | Generally yes | The baseline case the program was built for |
| Section 301 tariffs (China) | Generally yes | Often the largest single recoverable amount |
| Merchandise Processing Fee (MPF) | Generally yes | Small per entry, meaningful at volume |
| Harbor Maintenance Fee (HMF) | Generally yes | Applies to ocean freight entries |
| Section 232 tariffs (steel, aluminum) | No | Explicitly excluded from drawback |
| Antidumping / countervailing duties | No | Excluded by statute |
| IEEPA tariffs | Handled separately | Following the 2026 Supreme Court ruling, refunds run through their own CBP process, not drawback |
Eligibility rules change with trade policy and administrative guidance — confirm current treatment with a licensed customs broker before building a claim around any single tariff program.
The five-year window nobody uses
The most underappreciated feature of drawback is that it is retroactive. Claims can generally cover exports tied to imports going back five years.
For a business that has been importing and re-exporting for several years without filing, the first claim is not a small refund — it is five years of accumulated duty on every qualifying transaction. This is usually what makes the program worth setting up: the backlog pays for the infrastructure, and the ongoing claims are profit.
The catch is documentation. You need import entry summaries, proof of duties paid, export records with shipping documentation, and a defensible link between the two. If your records from three years ago cannot connect a specific export to a specific import entry, that portion of the backlog is gone.
What it costs and when the money arrives
Drawback is not a quick refund. The realistic timeline breaks into two phases.
- Setup and privileges approval: roughly 4 to 12 months. This is where CBP reviews your recordkeeping and grants the privileges that make ongoing claims practical.
- First refund: approximately 6 to 18 months from starting the process.
- Steady state, with accelerated payment privilege: refunds arriving roughly 3 to 6 weeks after a claim is filed.
Accelerated payment is the privilege worth pursuing. Without it, you wait for CBP to liquidate the entry, which can take years. With it, you are paid on filing and CBP reconciles afterward.
On cost: most companies use a drawback specialist or customs broker rather than filing in-house, because claims must be filed electronically through ACE and the recordkeeping standard is strict. Fee structures vary — contingency percentages of the recovered amount, flat per-claim fees, or a hybrid are all common in the market. Get the structure in writing, and confirm who bears the cost if CBP later disallows part of a claim.
Is your volume big enough?
Drawback has real fixed costs, so it does not make sense at every scale. A rough way to think about it:
- Clearly worth it: you pay six figures or more annually in recoverable duty and export a meaningful share of what you import. The five-year backlog alone justifies the setup.
- Worth modeling carefully: mid-five-figure annual recoverable duty. The answer depends heavily on how clean your records are — good ERP data makes this viable at lower volumes than messy spreadsheets do.
- Probably not yet: low import duty spend, or you export almost nothing. Revisit if your international sales grow.
The honest test is not « do I import a lot » — it is « do I import goods that later leave the country, and can I prove it. » Businesses that import for purely domestic sale have nothing to claim.
How to start
Before calling anyone, pull three things: your total duties paid by year for the past five years, your export volume over the same period, and a sample of records showing whether you can trace a given export shipment back to a specific import entry.
That third item is the one that decides everything. A specialist can tell you within one conversation whether your recordkeeping supports a claim — and if it does not, the fix for future claims is usually a matter of adding entry references to your export records, not rebuilding your systems.
Conclusion
Duty drawback is one of the few genuine cost-recovery programs available to U.S. importers, and the five-year retroactive window means the first claim is usually the largest cheque a shipping operation will receive all year. It is slow, it is document-heavy, and it is not worth it at every scale — but for anyone importing goods that later leave the country, ignoring it means donating up to 99% of recoverable duty to the Treasury.
