The recommendations unveiled by Secretary Wilbur Ross are likely to escalate tensions with China and other US trading partners.
Stepped-up production of steel and aluminum, especially by China, has driven down prices and hurt American producers.
The Commerce Department is recommending tariffs on all steel and aluminum imports, higher tariffs on imports from specific countries or a quota on imports.
The measures are meant to increase US production to 80 per cent of capacity in both industries. US steel plants are running at 73 per cent of capacity and aluminum plants at 48 per cent. Trump has until April 19 to make a decision.
