US imposes 50 per cent tariff on copper imports: Trump

The tariffs will exclude copper scrap and copper input materials such as copper ores, concentrates, mattes, cathodes and anodes, the statement said.

The measure came after a US investigation under Section 232, which US President Donald Trump ordered in February.

Along with tariffs, the order calls for steps to support the domestic copper industry, including requiring 25 per cent of high-quality scrap produced in the US to also be sold within the country.
