US tariffs on steel and aluminum doubled from 25% to 50%, a move cheered by the beleaguered American steel industry but worrisome to sectors that heavily use the metals, from car makers to can manufacturers.

Trump bulked up tariffs on foreign steel and aluminum after taking office for a second time, restoring the 25% levy that had been weakened by numerous country exclusions and quotas and thousands of product-specific exclusions.

Canada’s Mark Carney calls the 50-percent tariff increase ‘illegal’, while Mexico’s Sheinbaum weighs countermeasures.
