Manufacturing Drawback Overview
For shipyards, fabricators, and heavy industrial manufacturers, manufacturing drawback under 19 U.S.C. § 1313(a) and 1313(b) offers substantial duty recovery opportunities. When imported materials—steel plate, marine engines, electrical components, coatings—are incorporated into vessels or equipment that are subsequently exported, up to 99 percent of the duties paid on those materials can be recovered.
This is particularly valuable for yards building vessels for foreign buyers or producing offshore equipment destined for international projects. With today’s elevated tariff environment, manufacturing drawback can represent millions of dollars in recoverable costs.
How Manufacturing Drawback Differs
Unlike unused merchandise drawback where goods are exported in the same condition as imported, manufacturing drawback applies when imported materials undergo a manufacturing process and become part of a new article. The finished product need not have a different tariff classification than the imported components—even minor processing can qualify if it constitutes “manufacture” under the regulations.
The key distinction from other programs: you’re not exporting the imported goods themselves, but rather products that incorporate or are made from those imported goods.
Rulings Requirements
Before filing manufacturing drawback claims, you need either a Specific Manufacturing Ruling or must qualify under the General Manufacturing Ruling (T.D. 20-07). The General Ruling covers many common manufacturing scenarios and simplified the process significantly when TFTEA modernization took effect in 2019.
A Specific Ruling is required for products not covered by the General Ruling or when you need to establish specific manufacturing processes and waste allowances. The ruling application requires detailed documentation of your manufacturing process, bills of material, and how imported components are incorporated into finished goods.
Bill of Materials Requirements
Manufacturing drawback requires detailed bills of material (BOMs) showing both the HTS classification and value of each imported component in your finished product. This documentation requirement is more rigorous than unused merchandise drawback and requires tight integration between customs, procurement, and production data.
For shipyards, this means tracking imported steel, engines, electrical systems, and other components through production and linking them to specific vessel construction projects. The data requirements are substantial but so are the potential refunds.
The FTA Limitation
One significant limitation: manufacturing drawback on exports to Canada, Mexico, and Chile is subject to the “lesser of the two” rule. Only the lesser of the duties paid on import to the U.S. or the duties paid on import into the FTA country can be claimed.
Since FTA countries often have duty-free treatment for goods qualifying under the trade agreement, this can effectively zero out manufacturing drawback for exports to those destinations. This doesn’t affect exports to non-FTA countries, which remain fully eligible for the 99 percent refund.
