TORONTO (Reuters) - Canada will impose new quotas and tariffs on imports of seven categories of steel, the federal government said on Thursday, fresh measures to head off a potential rise in imports as overseas steelmakers shut out of the United States seek new customers.

A tariff of 25 percent will apply starting Oct. 25, 2018 to imports “in cases where the level of imports from trading partners exceeds historical norms,” the government statement said.

The products covered include heavy plate, concrete reinforcing bar, energy tubular products, hot-rolled sheet, pre-painted steel, among others.
