Steel and aluminum are heavily used in the automotive and construction industry, but are also used to manufacture goods and appliances. The decision mirrors the actions Trump levied during his first Administration, when he enacted a 25% tariff on steel and 10% tariff on aluminum, though some countries, including South Korea were exempt.

President Donald Trump said he will announce on Monday that the United States will impose 25% tariffs on all steel and aluminum imports, including from Canada and Mexico, as well as other import duties later in the week.
