On April 27, 2017,
President Donald Trump ordered a review of the aluminum imports and threats to
national security under the Trade Expansion Act of 1962. On March 8, 2018, President Trump signed an order to impose the
tariffs on steel and aluminum under Section 232 of the act and citing "national security" grounds. Trump continued the use of Section 232 in his
second term, applying tariffs on imported cars, small trucks, engines, and other auto parts, softwood timber and lumber, upholstered wooden furniture and kitchen cabinets, medium- and heavy-duty trucks, busses and their parts. When the
United States Supreme Court ruled in
Learning Resources v. Trump that his widespread
Liberation Day tariffs against all imports from several countries was unlawful under the
International Emergency Economic Powers Act authority Trump claimed, Trump pledged to find other ways to set tariffs without the help of Congress. Several have suggested Section 232 could be one of the options used. Section 232 tariffs are expected to be more difficult for courts to review as they typically defer to the executive branch for matters of national security, according to
The New York Times. Trump enacted 20% tariffs under Section 232 on branded pharmaceuticals, potentially increasing them by an additional 20% each year for five years, on April 2, 2026, citing a review by the Commerce Department claiming this fell under a national security issue. These would only apply to pharmaceutical manufacturers that had yet agreed to build plants within the United States, agreements that companies like
Pfizer,
AstraZeneca and
Novo Nordisk had already met, nor would apply to generic drugs. ==See also==
