US President Donald Trump has signed a proclamation ordering 50 per cent tariffs on certain copper imports, citing national security, the White House says.
The proclamation imposes a 50 per cent tariff on semi-finished copper products and copper-intensive derivative products as of August 1, according to a fact sheet released by the White House.
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.
