Background
Section 232 of the Trade Expansion Act of 1962 allows the US President to impose tariffs on imports that threaten national security. The mechanism was used for steel and aluminium tariffs in 2018 and is now aimed at unmanned aerial systems.
The Commerce Department opened a Section 232 investigation into UAS imports in July 2025, with a 270-day statutory deadline for a presidential decision. That clock expired around late March 2026 with no public tariff announcement. If tariffs are imposed, the 38% of Ukrainian drones still built with Chinese parts face an immediate cost shock, as do US integrators sourcing motors, flight controllers, and sensors from Shenzhen.
The investigation runs alongside FAR 52.240-1, which bans ASDA-covered drones from federal contracts, and the FCC Covered List, which blocks new product certifications. Together these three actions form a regulatory scissors closing on Chinese drone suppliers before domestic alternatives can scale.
