Section 232 tariffs hit unmanned aircraft systems and components

This proclamation imposes Section 232 ad valorem duties on certain unmanned aircraft systems, or UAS, and UAS components on national security grounds. It sets a 100% duty on UAS with a maximum take-off weight above 25 kilograms, UAS that integrate thermal imagers, UAS docking stations, and certain components in Annex I. It also sets a 25% duty on UAS with a maximum take-off weight of 25 kilograms or less in Annex II.

The proclamation also imposes a 25% duty on certain UAS components in Annex III, but that part takes effect later. The duties apply in addition to other duties, taxes, fees, exactions, and charges, unless the proclamation says otherwise. The Secretary of Commerce is authorized to add more UAS components to the tariff scope on a rolling basis through a Federal Register notice.

For products of Japan, the Republic of Korea, Taiwan, Switzerland, Liechtenstein, a member nation of the European Union, or the United Kingdom, the duty rate is capped at 15% or 10% depending on origin if substantially all critical components and technology are certified as originating in specified economies. The Secretary must establish a process for determining which products meet that standard and inform CBP. Separate temporary timing relief applies to covered products and components tied to companies on specified Defense, FCC, or related lists as of September 2, 2026.

The proclamation also directs the Secretary to establish an onshoring program for companies building new U.S. UAS production facilities. Approved plans can allow duty-free imports of covered products for the company's supply chain and necessary production equipment during construction, subject to conditions, monitoring, and possible rescission.
