U.S. plans to slap tariffs on aluminum imports from Canada, Bloomberg report says

The United States is planning to re-imposetariffsonaluminumimports from Canada, Bloomberg reported late on Monday, citing people familiar with the matter.

If Canada declines to impose export restrictions, the United States will announce on Friday the re-imposition of 10 per centtariffsonaluminumfrom the country, the report said.

Thetariffswould then be implemented by July 1, the report said, which is also when a new Canada-U.S.-Mexico Agreement on trade is expected to take effect.

Some industries, including automakers, had been asking for a delayed implementation of the agreement due to the difficulties they are facing amid the coronavirus pandemic.

The new North American Free Trade Agreement replaces the 26-year-old trade agreement between the three economies.

The office of the United States Trade Representative did not immediately respond to a Reuters request for comment onaluminumtariffs that was sent outside regular business hours.

Earlier in the day, the U.S. Supreme Court turned away a challenge to President Donald Trump'stariffson imported steel brought by an industry group that had argued that a key part of the law under which he imposed the duties violates the U.S. Constitution.

Trump signed a proclamation this year increasingtariffson derivative steel products by an additional 25 per centand on derivativealuminumproducts by an additional 10 per cent, from which countries including Canada and Mexico were exempted.
