Trump plans to impose 50% tariff on copper pipes and wiring

Move roils US prices as new policy falls short of US president's initial threats to introduce sweeping new levy

The Trump administration announced plans to impose a 50% tariff on copper pipes and wiring, roiling US prices after details of the levy fell short of the sweeping restrictions expected.

By leaving out copper input materials such as ores, concentrates and cathodes, the new policy will fall significantly short of Donald Trump's initial threats to introduce a sweeping new levy on overseas shipments of the metal.
