Effective August 1, 2025, as a result of a U.S. investigation under Section 232 that Trump ordered in February, U.S. President Donald Trump on Wednesday signed a proclamation ordering 50 per cent tariffs on certain copper imports, citing national security.
The tariffs will exclude copper scrap and copper input materials such as copper ores, concentrates, mattes, cathodes and anodes, the statement said.
