Canadian producers relieved as Trump’s 50% tariff on imported copper spare key products

U.S. President Donald Trump on Wednesday imposed hefty new tariffs on imported copper products, though the duties largely spare Canada’s mining and refining industry.

Mr. Trump set the tariff for a range of copper products at 50 per cent starting Aug. 1, citing national security concerns for his latest attempt to bolster his country’s manufacturing sector by raising trade barriers.
