London | The world’s largest copper producer says US tariffs are causing anxiety as the $US250 billion ($385 billion) industry awaits details of proposed levies on the metal less than two weeks before they are due to kick in.
President Donald Trump this month said he would impose a 50 per cent tariff on copper from August 1 but did not clarify if this would apply to the refined metal, semi-finished products or copper ore. Miners and industrial users have questions over the timing and nature of the tariffs.
