US Duty Drawback: How Taiwan Exporters Can Reclaim Import Duties They Already Paid

Duty drawback is a US Customs and Border Protection (CBP) program that allows importers to recover up to 99% of the customs duties, fees, and taxes paid on imported merchandise that is subsequently exported from the United States or destroyed under CBP supervision. The program is authorized under 19 USC 1313 and has existed in US law since 1789, making it one of the oldest trade programs in the country. Despite its long history, fewer than 10% of eligible importers file drawback claims — a missed opportunity that collectively costs US importers billions of dollars in unrecovered duties annually.

For Taiwan exporters selling on Amazon US, duty drawback is relevant when goods are imported into the US, duties are paid at the port of entry, and a portion of those goods are later re-exported — for example, returned customer goods that are shipped back to Taiwan, goods sold to a Canadian distributor and exported from the US, or goods destroyed as part of an Amazon disposal order (in specific circumstances). Each of these scenarios potentially qualifies for a drawback claim that recovers most of the original import duty.

The financial magnitude is significant. If you imported USD 500,000 worth of goods from Taiwan and paid a 10% import duty (USD 50,000), then subsequently exported USD 150,000 worth of those goods from the US back to Canada or another market, you are entitled to a drawback claim of up to USD 14,850 (99% of the USD 15,000 duty attributable to the exported portion). Over a full year of importing at scale, drawback claims can amount to USD 20,000–100,000 in recovered duties for Taiwan brands with significant cross-border return or re-export flows.

CBP processes drawback claims through its Automated Commercial Environment (ACE) system. Claims must be filed within 5 years of the original importation date. This 5-year window means that Taiwan sellers who have been importing into the US for several years may have unclaimed drawback entitlements from past import entries that are still within the filing window. A customs broker specializing in duty drawback can conduct a retroactive analysis of your import history and identify claimable amounts from past shipments.

Manufacturing drawback (19 USC 1313(a)) applies when imported merchandise is used as a component in the manufacture of an article that is subsequently exported. This is the most commonly claimed type for US manufacturers who import raw materials or components. For Taiwan brands, this applies if you import components into the US, assemble a finished product at a US facility, and export the assembled product. A Taiwan electronics company that imports circuit boards, assembles them into a finished device at a US contract manufacturer, and then exports devices to Canada qualifies for manufacturing drawback.

Unused merchandise drawback (19 USC 1313(j)(1)) applies when imported goods are exported in the same condition as imported — without processing, manufacturing, or use in the US. This is the most directly applicable type for Taiwan Amazon sellers who import goods, store them in Amazon's FBA warehouses, and then export a portion of those goods to another market. If your FBA inventory is removed and shipped to a Canadian distributor without being used or altered in the US, the duties on those units qualify for unused merchandise drawback.

Substitution unused merchandise drawback (19 USC 1313(j)(2)) is a more flexible version that allows you to claim drawback based on exported merchandise that is commercially interchangeable with the imported merchandise, even if it is not the exact same physical units. If you imported 1,000 units of a product and paid duty, and later exported 300 units of a commercially interchangeable product (same HTS code, same quality), you can claim drawback on the exported 300 units even if you can't prove they are the exact physical units from the original import. This substitution rule is powerful for Amazon sellers with high inventory turnover and commingled stock.

Rejected merchandise drawback (19 USC 1313(c)) applies when imported merchandise is returned to the foreign seller because it does not conform to specifications or was shipped without the importer's consent. If your Taiwan factory ships defective goods that fail quality inspection at the US port and you return them to Taiwan, rejected merchandise drawback covers 99% of the duties that were paid before inspection revealed the defect. Document the rejection with a CBP Form 4315 and your factory's acknowledgment of the returned goods to support the claim.

To qualify for drawback, you must have paid US import duties on the original importation — duty-free goods under trade agreements or de minimis entries are not eligible. You must be able to prove the link between the imported merchandise and the exported merchandise through documentation: import entry documents (CBP Form 7501), commercial invoices, packing lists, bills of lading for both the import and export shipments, and proof of export (export entry summary or shipper's export declaration).

Recordkeeping requirements under 19 CFR Part 191 are strict. You must retain all records supporting a drawback claim for 3 years after the date the drawback claim is liquidated (finally settled) by CBP. Given that CBP can take 2–5 years to liquidate a drawback claim, this means maintaining records for potentially 7–8 years from the original import date. Records must be stored in a format CBP can audit — electronic records are acceptable, but they must be complete, unaltered, and accessible within 30 days of a CBP records request.

Your company must be the importer of record on the original US customs entry to file a drawback claim directly. If your Taiwan company is not the importer of record (for example, if you use a freight forwarder's IOR service), the drawback entitlement legally belongs to that importer of record, not your company. Resolve IOR status before large import shipments if you intend to claim drawback — use your US LLC as the IOR and ensure your customs bond covers the import entries you plan to claim drawback on.

The most common eligibility failure for Taiwan sellers is the inability to document the export side of the transaction. Drawback requires proof that the goods physically left US territory as an export — an Amazon disposal or destruction order does not automatically qualify as an export, and Amazon's removal order documentation is typically insufficient as standalone export evidence. Work with a licensed customs broker to ensure that exports intended to support drawback claims are filed as formal export entries through CBP's ACE system, generating the Electronic Export Information (EEI) filing in the Automated Export System (AES) that CBP requires as export proof.

Step one is engaging a licensed customs broker who specializes in duty drawback. Most generalist customs brokers file import entries but have limited drawback experience — drawback is a specialized area with its own regulatory framework, calculation methodology, and ACE filing requirements. Ask prospective brokers how many drawback claims they file per year and in which categories. Firms like Livingston International, Comstock & Theakston, and customs brokers affiliated with major freight forwarders (Expeditors, Kuehne + Nagel) have dedicated drawback departments.

Your customs broker will conduct an initial eligibility analysis using your import entry history from CBP's ACE system and your export records. This analysis produces an estimate of your claimable duty amount and identifies which entries are within the 5-year filing window. The analysis fee ranges from USD 500–2,000 depending on the complexity of your import history. Most drawback specialists work on a contingency basis — they charge 15–25% of the recovered duty amount and charge no upfront fee if no drawback is recovered.

Once the analysis is complete, your broker files the drawback claim electronically through ACE using Form 7551 (Drawback Entry). The claim identifies each import entry on which duties were paid, each export shipment that qualifies as the exported merchandise, the duty calculation methodology (specific or accounting method), and the refund amount claimed. CBP reviews the claim, may request additional documentation, and eventually liquidates (settles) the claim — issuing a refund check or ACH payment to your designated bank account.

Processing times vary significantly. Simple unused merchandise drawback claims with clean documentation are liquidated within 12–24 months of filing. Complex manufacturing drawback claims or claims involving substitution may take 3–5 years. CBP has faced backlash over slow drawback processing, and the Trade Facilitation and Trade Enforcement Act (TFTEA) of 2015 introduced accelerated payment provisions that allow claimants who waive accelerated payment privileges to receive payment faster. Discuss the timing tradeoffs with your customs broker when structuring the claim.
