Trade court weighs Trump's 10% replacement tariffs under an old law

A three-judge panel at the U.S. Court of International Trade is weighing whether President Trump properly invoked the 1974 Trade Act to reimpose a 10% global tariff, a measure limited to 150 days and intended as a bridge after the Supreme Court struck down broader tariffs. The hearing highlighted uncertainties about applying a 1970s-era provision to today’s economy, with DOJ defending the authority and opponents arguing the statute is obsolete and may require clearer congressional authorization. A ruling could shape Trump’s tariff strategy and the broader trajectory of U.S. trade policy.
