In a statement, the White House announced that President Trump signed a proclamation imposing tariffs ranging from 10% to 100% on imported drones and parts, citing national security threats. The proclamation specifies a 100% tariff on drones with highly sensitive specific sizes or functions, as well as docking stations for such drones and certain critical components. This category includes drones with a maximum takeoff weight exceeding 25 kilograms and those equipped with thermal imaging capabilities. Additionally, a 25% tariff will be applied to certain smaller drones and other drone components that do not possess specific functions. The announcement also states that a 15% tariff will be imposed on drones and components from the European Union, Japan, Liechtenstein, South Korea, and Switzerland. Furthermore, a 10% tariff will be levied on drones from the UK, provided that their hardware, software, and technology primarily originate from the aforementioned countries and regions, as well as the US. The tariffs are set to take effect 21 days after the signing, while tariffs on non-highly sensitive drone components will take effect 180 days after the signing.
