Commerce Will Let Drone Makers Import Duty Free While an American Plant Is Under Construction

President Trump issued a proclamation under Section 232 of the Trade Expansion Act of 1962 on August 13, 2026 covering unmanned aircraft systems and their components. Annex I carries a 100% ad valorem duty on aircraft with a maximum takeoff weight above 25 kilograms, aircraft that integrate thermal imagers, docking stations and named critical components, and Annex II carries 25% on aircraft at or under 25 kilograms, both applying to goods entered for consumption on or after 12:01 a.m. Eastern on September 3, 2026. Annex III adds 25% on further components from February 9, 2027. The duties stack on top of existing Section 301 and Section 232 rates. Products of the European Union, Japan, Korea, Taiwan, Switzerland and Liechtenstein are capped at 15% and products of the United Kingdom at 10%, but those caps are all-in ceilings that include the standard rate and they apply only where the importer certifies that substantially all critical components and technology are of United States or qualifying country origin. The proclamation does not define substantially all, and Commerce has not designed the verification process.

The clause that belongs in an attraction file is the onshoring program. The proclamation directs Commerce to run a scheme under which a company with an approved onshoring plan may import covered products for its supply chain, including components for both finished and unfinished aircraft, together with the production equipment needed to build the plant, free of the Section 232 duties while the American facility is under construction. Import volumes must be commensurate with the facility's reasonably anticipated annual output once complete. To qualify, the company must commit to constructing, refurbishing or expanding a United States production facility for aircraft or components, with construction commencing before January 20, 2029. Commerce may audit participants, including through outside auditors, may rescind the benefit prospectively where a company substantially fails to meet its commitments, and may rescind it retroactively where it finds fraud or deliberate misrepresentation, exposing the company to back duties, fines and penalties.

That makes the decisive money on a new American drone plant a federal duty waiver, and the waiver is not denominated the way a state package is. It is worth the full duty, which is 100 cents on every dollar of Annex I content and 25 cents on every dollar of Annex II content, for every year construction runs. There is no ceiling in the proclamation and no payroll or capital investment threshold attached to the benefit itself, only the requirement that imports match the plant's expected output. A state or regional agency negotiating the same project is bidding around a term it cannot see, cannot price and cannot award.

The published approval criteria are thin. Commerce will consider whether the applicant already holds a Department of Defense or Department of Homeland Security Conditional Approval, which is what allows foreign aircraft and components to obtain FCC equipment authorisation despite the Covered List. It will consider the commercial reasonableness of the project timeline and milestones. It will consider the broader economic benefit of the proposal. All three are discretionary and all three favour an applicant that files early with documentation already assembled. Separately, companies on the Blue UAS Cleared List, inside the Blue UAS Framework, or on the FCC's Conditional Approval List as of September 2, 2026 get a 180-day delay before the Annex I and Annex II duties apply to them, which means the status check has a date on it before the tariff does.

The rest of the mitigation routes are narrower than they look. Covered products admitted to a foreign trade zone on or after the effective date must enter under privileged foreign status, which fixes the duty rate at admission and takes zone processing off the table as a way to reduce it. Manufacturing drawback under 19 U.S.C. 1313(a) and (b) survives, but only for articles subject to no antidumping or countervailing duty order, that are products of a designated trade agreement partner, and that contain at least 85% trade agreement partner content, a threshold that current motor, battery and flight electronics supply chains will struggle to clear. Commerce may also add components to Annex I or Annex II by Federal Register notice at any time, with no further presidential action and no notice and comment, so a bill of materials priced this week can change without warning.

The strongest objection is that this instrument is not new and Commerce will simply copy its own file. That is correct and worth stating plainly. After the April 2, 2026 pharmaceutical proclamation, Commerce published procedures for company-specific onshoring agreements at 2026-09489 on May 13, 2026, requesting applications by June 12 to an email address, with an approved agreement cutting the pharmaceutical rate to 20% from September 29, 2026 through April 2, 2030, and an onshoring agreement combined with a most-favoured-nation pricing agreement cutting it to zero from July 31, 2026 through January 20, 2029. Applications had to set out total new United States investment planned between January 20, 2025 and January 20, 2029, a commitment to audited progress reports against investment milestones, and a senior officer certification. A template exists, and outside counsel expect the drone equivalent within weeks.

The precedent is also the warning. Commerce gave pharmaceutical companies 30 days between publishing the procedures and closing applications, set no deadline on its own decisions, announced no second window, and as of the publication date had not posted the application form on the Bureau of Industry and Security website. If the drone program runs on the same clock, a company will choose a site and file a tariff application inside the same month, and the only agencies in the room will be those holding a shortlisted site with a signed option, a completed power study and a defensible construction start date before the notice publishes. An agency that starts assembling that file when the Federal Register notice appears will be assembling it after the decision.
