The U.S. Commerce Department has initiated national security investigations into imports of drones, related components, and polysilicon, a critical material used in solar panels and semiconductor manufacturing. The probes, launched under Section 232 of the Trade Expansion Act, began on July 1, 2025, and could lead to the imposition of tariffs on these goods if they are deemed a threat to national security. This move aligns with the Trump administration's broader trade policy agenda aimed at protecting domestic industries. Polysilicon is essential for producing solar power panels and chips, while drones and their parts are increasingly significant in various sectors. The investigations signal potential new trade restrictions targeting these strategic imports.
