In 2021, the U.S. Court of International Trade struck down the new tariffs, saying the White House missed statutory deadlines to impose them.
But the appeals court said a subsequent ruling allowed presidents to impose "contingency-dependent" tariff increases to fulfill their original national security objectives, assuming those objectives remained valid. Trump imposed the new tariffs to "close a loophole exploited by steel-derivatives importers ... to address a specific form of circumvention," Circuit Judge Richard Taranto wrote.
The Biden administration supported upholding the new tariffs.
The tariffs had been challenged by importers Huttig Building Products Inc, Oman Fasteners LLC and PrimeSource Building Products Inc, which said Congress never granted the president broad power over foreign trade to impose them.
Lawyers for the importers did not immediately respond to requests for comment. The Commerce Department did not immediately respond to a similar request.
The cases are PrimeSource Building Products Inc v U.S.
et al, U.S. Federal Circuit Court of Appeals, No. 2021-2066; and
Oman Fasteners LLC et al v U.S. et al in the same court, No.
2021-2252.
