Duty drawback: how to claim your refund

Duty drawback is a refund of duties, taxes and fees you paid on imported goods that later leave the country or are destroyed. The refund is 99 percent of what you paid, set by statute at 19 USC 1313, with CBP keeping 1 percent for administration. You have five years from the date of import to file, claims are filed electronically in ACE, and the Merchandise Processing Fee and Harbor Maintenance Fee come back along with the duty. The catch that decides whether a program is worth building: Section 301 duties are refundable, but Section 232 metals duties and antidumping or countervailing duties are not.

That last point is where most published guidance is wrong, and it is worth getting right before you model anything, because for a lot of importers the Section 232 exposure is the single largest line on the entry.

What comes back, and what does not

CBP said it plainly in CSMS 18-000498: Section 301 duties are eligible for duty drawback. It said the opposite about metals in CSMS 18-000317: no drawback is available with respect to the Section 232 duties imposed on any aluminum or steel article. Both messages still stand. The June 2026 proclamation that further adjusted the aluminum, steel and copper regimes contains no drawback language at all, so it did not disturb the original prohibition.

The filing mechanics differ too. On a claim that includes Section 301 duties you must report both the Chapter 99 special tariff number, the 9903 series code, and the ordinary Chapter 1 to 97 classification, with quantity and value, in the same order they appear on the underlying import entry in ACE. Claims that list only the ordinary classification leave the 301 money on the table.

One 2026 note that will date quickly. The Section 122 import surcharge of 10 percent, introduced in February 2026 after the Supreme Court held that IEEPA does not authorize tariffs, was drawback-eligible per CBP's own message, and it was scheduled to expire by operation of law around July 24, 2026 under the 150-day statutory cap on that authority. Separately, duties collected under the voided IEEPA program are being refunded through a dedicated CBP process rather than through drawback. If any of your entries touch that period, confirm the current position with CBP before filing, and make sure you are not claiming the same dollars twice through two different refund channels.

The three kinds of drawback

Almost every real claim fits one of three statutory buckets.

Unused merchandise drawback, 19 USC 1313(j). You imported goods, paid duty, and then exported or destroyed them without using them in the United States. Under (j)(1), direct identification, you export the same merchandise and trace it by lot, serial number or an approved accounting method. Under (j)(2), substitution, you may export other merchandise classifiable under the same eight-digit HTS subheading as what you imported, without tracing the specific unit. This is the workhorse for distributors and anyone who re-exports inventory.

Manufacturing drawback, 19 USC 1313(a) and (b). You imported materials, manufactured something in the US, and exported the finished article. Under (a) you identify the actual imported material. Under (b) you may substitute domestic or duty-free material classifiable under the same eight-digit subheading, provided it is used in manufacture within five years of the import date. Manufacturing drawback requires an approved ruling first, either a general manufacturing drawback ruling you adopt or a specific ruling you apply for, so it carries more setup than the unused route.

Rejected merchandise drawback, 19 USC 1313(c). For duty-paid goods that did not conform to sample or specification, were shipped without the consignee's consent, were defective at import, or were sold at retail and returned. They must be exported or destroyed within five years of import. The retail-return branch is the one ecommerce sellers routinely overlook.

The substitution rule, and the trap inside it

The Trade Facilitation and Trade Enforcement Act replaced the old "commercially interchangeable" test with a classification test, which made substitution far more usable. If the imported and substituted goods sit under the same eight-digit HTS subheading, substitution is allowed.

Then comes the exception that kills more claims than any other. If that eight-digit subheading's article description begins with the word "other," substitution is prohibited unless both articles fall under the same ten-digit statistical reporting number, and that ten-digit description must itself not begin with "other." A large share of the tariff schedule's basket provisions begin with "other," so this bites constantly. Anyone modeling a substitution program needs to read the actual article descriptions of their codes, not just match the digits.

There is also a ceiling. On substitution claims the refund is 99 percent of the lesser of the duties paid on the imported merchandise or the duties that would have applied had the exported article been imported. You cannot import a cheap version, export an expensive one and collect on the difference.

The clocks you have to track

Pay attention to the retention rule, because a lot of guidance still states it as three years from payment of the claim. That was the rule before the Trade Facilitation and Trade Enforcement Act, which substituted "liquidation" for "payment" in 19 USC 1508(c). The distinction is not academic. If you take accelerated payment you may receive the money years before the drawback entry liquidates, and the retention clock does not start until liquidation. Since TFTEA-era drawback entries are generally deemed liquidated at five years, total retention can run toward eight years from filing. Purging records on a general five-year schedule is a reliable way to lose a claim you already collected on.

How claims actually get filed

Drawback is electronic only. Paper filing ended on February 23, 2019, and from February 24, 2019 all claims have been filed in ACE under the modernized rules in 19 CFR Part 190. There is no manual fallback.

Two one-time privileges are worth applying for at the outset, because both change the cash and operational profile of a program and neither has to be renewed per claim.

Accelerated payment under 19 CFR 190.92 means CBP pays estimated drawback before the entry liquidates. Without it you wait for liquidation, which can take years. CBP notifies applicants in writing within 90 days, and grants it only where its review finds no omissions or inconsistencies with the drawback rules. Because CBP is paying out before verifying, an approved claimant must post a bond sufficient to cover the estimated drawback claimed during the bond's term, and if outstanding accelerated claims exceed the bond amount CBP requires more coverage before paying further. The bond is simply CBP's security if the claim is later cut or denied. If you already carry a continuous bond for imports, this is a separate activity on top; the mechanics are similar to what we cover in how customs bonds work.

Waiver of prior notice under 19 CFR 190.91 removes the requirement to file a Notice of Intent to Export, Destroy, or Return, CBP Form 7553, at least seven working days before every export or destruction. For a company shipping continuously, that advance notice is unworkable, so the waiver is close to essential. You can apply for either privilege alone or both in one combined package under 19 CFR 190.93, as long as every required sample document and certification for each is included.

Who gets the money

This surprises people: the importer is not automatically the claimant. Under 19 CFR 190.82 the exporter or destroyer is entitled to claim drawback by default, even though the importer paid the duty. Where those are different companies, the exporter may waive and assign the right by written certification to the manufacturer, producer, importer or an intermediate party. The certification has to confirm that the exporter has not assigned and will not assign the right for that same exportation to anyone else, because the right cannot be split across multiple claimants for one transaction.

The paperwork for transfers got simpler after TFTEA. The old Certificates of Delivery and Certificates of Manufacture and Delivery are gone as separate required forms; 19 USC 1313(b)(2)(C) allows transfers to be evidenced by business records kept in the normal course of business. The underlying traceability obligation did not go away, only the specific form did. Any guidance still telling you to file a CD or CMD is describing the pre-2019 regime.

Is a drawback program worth running?

Honest answer: it depends on the duty rate and the export ratio far more than on import volume, and the setup cost is real.

For scale, the Government Accountability Office found in its 2019 review that the program refunds roughly a billion dollars a year, and that as of August 2019 more than 35,000 claims representing an estimated two billion dollars had been filed without full desk review. That same report is the clearest official statement that the program carries meaningful error risk, which is worth knowing before you assume a claim will sail through.

You will find a lot of specific-sounding numbers online about typical contingency fees, program minimums and billions in unclaimed refunds. Those figures trace to drawback vendor marketing rather than to CBP or GAO, so treat them as sales copy. What can be said accurately is that specialist filers commonly work on a contingency basis, taking a percentage of what they recover rather than billing hourly, which removes upfront cost and aligns incentives, and that larger firms tend to set account minimums that push smaller importers toward mid-size brokers.

The factors that actually determine whether it pays:

• Duty rate matters more than volume. A high-rate importer with modest volume can easily beat a low-rate importer with large volume. Apparel, footwear and other high-tariff categories are the classic candidates.
• The export or destruction ratio is the real driver, since you only recover on the proportion that leaves.
• Section 232-heavy importers should temper expectations, because that money is simply not recoverable.
• Setup is front-loaded: privilege applications, a manufacturing ruling if you need one, data mapping between import and export systems, and a recordkeeping regime that has to survive until three years after liquidation.

Why claims fail

Weak record linkage between import and export. This is the structural problem. GAO found CBP cannot readily verify claims against underlying export information because its system does not hold detailed export data, which is exactly why the evidentiary burden sits with you and gets audited hard. If your systems cannot tie an export line back to a specific import entry line, or to an approved accounting method, the claim will not survive review. Companies that run drawback well generally have deliberate lineage between the records on each side of the transaction rather than a spreadsheet reconstructed after the fact.

Inadequate proof of export. 19 CFR 190.51 requires evidence including a unique export identifier, the destination, the exporter's name, and a certification that the exported article is not to be relanded in the United States. Bills of lading on their own are frequently held insufficient.

Substitution standard not met. Usually the "other" trap described above, where everyone assumed eight-digit matching was enough. Sometimes the lesser-of rule quietly cutting the refund below the model.

Destruction not properly supervised. You must file CBP Form 7553 at least seven working days before destroying goods. CBP then has four working days to say whether it will witness. If CBP does not respond in time you may destroy without delay and it is deemed to have occurred under CBP supervision, but if CBP simply does not attend you need evidence from a disinterested third party, such as a landfill operator, that the destruction happened as described. Destroy first and paper it afterwards and you have no claim. Remember also to deduct the value of any recovered materials from the value of the destroyed merchandise.

Late transmission. A claim not successfully transmitted within five years of import is considered abandoned, and there is no cure short of a major disaster.

Where classification fits in

Drawback is a classification-driven program from end to end. Substitution turns on the eight-digit subheading and, when the description begins with "other," on the full ten-digit number. The lesser-of calculation compares duty rates that only exist once both sides are classified. And the Section 232 exclusion means you need to know which of your lines are caught by the metals action before you can forecast a refund at all.

In other words, a drawback program built on sloppy classification will produce a refund estimate that does not survive audit. If you want the code and the reasoning behind it, describe your product in the classifier at the top of this page, or work through the method in how to find the HS code for a product. Drawback is also only one of several legal ways to bring duty down, and it is often not the first one worth trying; the full set is laid out in how to reduce import duties legally.
