Trump on Sunday said he was going to put tariffs on imports of all steel and aluminum, used by automakers, aerospace companies, and in construction and infrastructure.
The U.S. is the world's largest aluminum importer, according to World Bank data. It has had a trade deficit in steel for a decade, according to the International Trade Administration. It is the second largest steel importer worldwide, with more than half of those volumes coming from Canada, Mexico and Brazil.
