Duty drawback is a CBP program that refunds up to 99% of import duties, taxes, and fees paid on goods that are subsequently exported. The legal authority is 19 USC §1313. The operating regulations are 19 CFR Part 190, substantially updated by the Trade Facilitation and Trade Enforcement Act of 2015 (TFTEA). If your company imports goods and exports finished products, you are likely leaving recoverable tariff dollars unclaimed. The five-year filing window means duties paid as far back as 2021 may still be recoverable on exports made through 2026.
CBP administers drawback claims through the ACE Drawback module. All claims are filed electronically. The 1% retained by CBP (the 99% cap) is non-recoverable. Everything else is refundable if the claim is properly documented and filed within the statutory window.
Types of Duty Drawback
TFTEA simplified and expanded the drawback program. Four types of drawback are available under 19 USC §1313 and 19 CFR Part 190.
Manufacturing Drawback (§1313(a) and §1313(b))
An importer pays duties on raw materials or components. Those materials are used to manufacture a finished product. The finished product is exported. The importer recovers up to 99% of the duties paid on the imported inputs. This applies both to direct identification drawback (§1313(a), where the specific imported material is traced to the export) and to manufacturing substitution drawback (§1313(b), where commercially interchangeable domestic or imported materials are substituted). Manufacturing drawback is the highest-value drawback type for industrial importers and manufacturers.
Unused Merchandise Drawback (§1313(j))
Goods are imported, never used in manufacturing, and exported in their original condition. The importer recovers up to 99% of duties paid. Under TFTEA‘s post-2019 rules, substitution unused merchandise drawback allows commercially interchangeable goods to be substituted. The export does not have to be the exact same physical unit that was imported, only a commercially interchangeable equivalent. This dramatically expands the pool of eligible export transactions.
Rejected Merchandise Drawback (§1313(c))
Goods are imported and subsequently found to be defective, not conforming to specifications, or shipped without consent of the consignee. The importer exports or destroys the goods and recovers up to 99% of duties paid. CBP must witness the destruction or receive documentation of the export. This type applies to quality control failures and mis-shipped goods.
Substitution Drawback (Post-TFTEA)
TFTEA‘s most significant change was the expansion of substitution rights across all drawback types. Previously, substitution required the substitute merchandise to be of the same kind and quality as the imported merchandise. TFTEA replaced that standard with commercial interchangeability, a more flexible test. If a product is commercially interchangeable with the imported good (as determined by its HTS 8-digit classification, grade, quality, and other commercial standards), it can serve as the basis for a substitution drawback claim. This allows companies with complex supply chains to pool imports and exports across a 180-day matching window under TFTEA rules.
How Much Can You Recover (99% Rule)
The recovery is 99% of all import duties, including Section 301 duties, Section 232 duties, Harbor Maintenance Fees (where applicable), and the Merchandise Processing Fee. The 1% CBP retention is statutory and not waivable. On a company with $5 million in annual import duties and $2 million in qualifying exports, the annual drawback opportunity can exceed $1.8 million. The Captain duty drawback module calculates your drawback opportunity by matching import entries against export records automatically.
Filing Window and Timeline
Under TFTEA, the drawback claim must be filed within five years of the date of import of the merchandise on which drawback is claimed. The export must occur within five years of the import. The old three-year filing window was extended to five years by TFTEA. For claims based on TFTEA‘s substitution rules, the import and the export must each fall within the TFTEA effective period (February 24, 2016 onward). Claims are filed electronically through the ACE Drawback module. CBP has 365 days to liquidate the claim. Interest accrues on unpaid claims if CBP does not liquidate within the statutory period.

Section 301 Drawback Status
Section 301 duties are eligible for duty drawback. CBP confirmed this in multiple guidance documents. An importer who paid Section 301 duties on Chinese components used in manufactured goods that were subsequently exported can recover up to 99% of the Section 301 duties paid on those components. This is one of the most valuable drawback opportunities in the current tariff environment given the scale of Section 301 duty payments since 2018.
Section 232 Drawback Status
Section 232 duties are eligible for duty drawback. The same 99% recovery rule applies. Steel and aluminum importers who use covered materials in manufactured goods for export should audit their drawback eligibility immediately. The five-year window means Section 232 duties paid as far back as 2021 may still be recoverable on qualifying exports.
IEEPA Drawback Status
IEEPA duties imposed under the Reciprocal Tariff Act are NOT eligible for duty drawback. Executive Order 14257 (April 2025) and subsequent executive actions explicitly excluded IEEPA-based tariffs from the drawback program. This is a critical distinction. Before filing a drawback claim that includes IEEPA duty payments, verify the duty type at the entry level. Mixing eligible and ineligible duties in a single claim without segregation creates compliance risk. The IEEPA tariff refunds page covers the limited recovery pathways available for IEEPA duties outside of drawback.
AD/CVD Drawback Status
Antidumping and countervailing duties are NOT eligible for duty drawback under 19 USC §1313. This is a long-standing statutory exclusion, not a recent policy change. Importers paying AD/CVD duties on imported merchandise have no drawback recovery pathway for those specific duties, even if the goods are subsequently exported.
Documentation and Recordkeeping Requirements
Drawback claims require documentation of both the import and the export transaction. For manufacturing drawback, the importer must also document how the imported material was used in production. Required records typically include: import entry summaries (CBP Form 7501), commercial invoices and packing lists for imports, export documentation (airway bills, ocean bills of lading, export declarations), production records showing material usage, and proof of export from the U.S. Records must be maintained for three years after the claim is liquidated. The CBP Drawback Compliance Handbook provides detailed guidance on documentation standards. The trade advisory services team reviews recordkeeping systems before the first claim is filed to prevent rejection.
Drawback as a Tariff Strategy Lever
Duty drawback integrates into the broader tariff strategy toolkit alongside the Foreign-Trade Zones and customs bonded warehouse strategy. The decision between FTZ, bonded warehouse, and drawback depends on your ratio of imports to exports, your manufacturing process, and your cash flow timing. For companies with significant re-export or export operations, drawback often produces the highest dollar return because it recovers duties already paid rather than deferring future obligations. The First Sale for Export program reduces the dutiable value at entry, which reduces the duty base from which drawback is calculated. Combining both programs can maximize total duty reduction.
Frequently Asked Questions
What is duty drawback?
Duty drawback is a CBP program under 19 USC §1313 that refunds up to 99% of import duties paid on goods that are subsequently exported. It applies to finished goods manufactured from imported inputs (manufacturing drawback) and to imported goods exported without use (unused merchandise drawback).
How much can I recover with duty drawback?
Up to 99% of eligible import duties paid. CBP retains 1% as a statutory fee. Harbor Maintenance Fees and Merchandise Processing Fees are also recoverable on qualifying claims.
How long do I have to file a drawback claim?
Five years from the date of import of the merchandise on which drawback is claimed. TFTEA extended the window from three years to five years. The export must also occur within five years of the import.
Are Section 301 duties eligible for drawback?
Yes. Section 301 duties are fully eligible for duty drawback. CBP has confirmed this in guidance. Importers who used Section 301-affected Chinese inputs in exported manufactured goods should audit their recovery opportunity immediately.
Are Section 232 duties eligible for drawback?
Yes. Section 232 duties on steel, aluminum, and copper are eligible for duty drawback under the standard 99% recovery framework. Steel and aluminum manufacturers who export finished goods should file drawback claims for duties paid on imported inputs.
What is substitution drawback?
Substitution drawback allows commercially interchangeable merchandise to substitute for the specific imported goods in a drawback claim. TFTEA expanded this by replacing the old same kind and quality standard with a commercial interchangeability test. This allows companies to match imports against exports across a 180-day window without direct physical tracing.
Do I need a customs broker to file drawback claims?
Not legally required, but practically necessary for complex claims. Drawback claims require detailed matching of import entries to export records and documentation of manufacturing usage. Errors in drawback claims can result in rejection, interest charges, or penalties. A licensed customs broker with ACE Drawback module experience handles the filing and CBP audit response.
If your company exports, it is likely leaving tariff dollars on the table. The Captain duty drawback module matches import entries against export records automatically and calculates your drawback opportunity in real time. The trade advisory services team builds the claim file, manages CBP correspondence, and targets the five-year window to recover the maximum amount on duties paid since 2021.
