US sets up to 100% tariffs on drones and components from September 3

The US president signed Proclamation 11055 following a Section 232 investigation under the Trade Expansion Act of 1962, imposing steep tariffs on imports of unmanned aircraft systems (UAS) and their components. The proclamation was signed August 13, 2026 and published in the Federal Register on August 19, 2026 (Vol. 91, No. 159, document 2026-16979). Base rates take effect at 12:01 a.m. eastern time on September 3, 2026, with a delay until February 9, 2027 for part of the component tariffs.

How the rates break down by category

The proclamation splits covered goods into three annexes with different rates and timelines:

Annex I — 100%: UAS with a maximum takeoff weight exceeding 25 kg, thermal-imaging UAS, UAS docking stations, and select critical components.
Annex II — 25%: UAS weighing 25 kg or less.
Annex III — 25%: an additional list of critical components, delayed until February 9, 2027.

Preferential caps and qualifying conditions

Several allied economies get capped rates, provided "substantially all critical components and technology" of the product are certified as originating there:

European Union, Japan, South Korea, Taiwan, Switzerland and Liechtenstein — capped at 15%.
United Kingdom — capped at 10%.

A separate 180-day delay (until February 9, 2027) applies to companies listed as of September 2, 2026 on the Department of War's Blue UAS Cleared List or Blue UAS Framework, or on the FCC's Conditional Approval List — covering their listed products and components.

A duty drawback also applies to goods with at least 85% content from trade-agreement partner countries (UK, EU, Switzerland, Liechtenstein, Japan, South Korea, Mexico, Canada and future partners), excluding goods already subject to antidumping or countervailing duties.

What it means for importers

The tariffs hit importers of finished drones, thermal-imaging UAS, docking stations and components — from consumer and commercial UAS makers to integrators relying on imported subassemblies. Full tariff-line detail sits in the annexes (changes apply to subchapter III of chapter 99 of the Harmonized Tariff Schedule), so the annex text matters more than the proclamation's body. The Secretary of Commerce may add components to the covered lists via a Federal Register notice if imports threaten national security — coverage could expand after September.

A separate track exists for manufacturers: duty-free entry under an approved plan to build US manufacturing capacity, provided a construction commitment is locked in before January 20, 2029. Approval is coordinated with the Department of War (DoW) and the Department of Homeland Security, with ongoing compliance monitoring; violations can trigger retroactive rescission of the benefit plus additional penalties.

Timeline and transition period

September 3, 2026 — Annex I (100%) and Annex II (25%) duties take effect; a company's eligibility for the Blue UAS/FCC delay is based on its listing status as of September 2, 2026.
February 9, 2027 (180 days from signing) — Annex III duties take effect, and the Blue UAS/FCC delay ends.
Within 120 days of signing, the Secretary of Commerce must report on import trends; the deadline for a construction commitment under the onshoring program is January 20, 2029.
