The United States Court of International Trade on Wednesday began hearing a fresh challenge to President Donald J. Trump’s tariffs on goods from 60 trading partners, turning another chapter of America’s increasingly complicated tariff saga into a courtroom drama. The duties, imposed in July under Section 301 of the Trade Act of 1974, range from 10% to 12.5% and cover more than 99% of U.S. imports. Four small businesses and 25 Democratic-led states argue that the administration exceeded its legal authority, while the Trump administration says its investigations established grounds for the measures.
Court Examines Legal Authority Behind Trump’s New Tariffs
The latest dispute arrives months after the U.S. Supreme Court ruled on February 20 that the International Emergency Economic Powers Act did not authorize the president to impose tariffs. The ruling concerned Trump’s earlier broad tariffs, prompting the administration to search for another legal route. Trump subsequently turned to other statutory authority, with the forced-labor tariffs now facing their own examination in the trade court.
That legal journey has produced something of a tariff relay race: when one legal route reached the Supreme Court’s finish line, another authority was quickly brought onto the track. In July, the Office of the U.S. Trade Representative announced action against 60 economies under Section 301, saying the investigations examined whether those economies failed to prohibit or effectively enforce bans on imports produced with forced labor. The White House says the investigations began in March and involved public hearings, comments and engagement with trading partners.
Businesses and States Question the Legal Shortcut
At the trade court hearing, attorney Pratik Shah, representing two of the small businesses challenging the tariffs, argued that the administration had used a tariff authority that Congress intended to be limited. The lawsuits contend that country-specific findings were required and that the administration’s approach effectively recreated a broad tariff power that the Supreme Court had rejected under a different statute.
The administration disputes that characterization. Its court filings maintain that genuine investigations were conducted into the 60 trading partners and that the findings supported tariffs because of failures relating to forced-labor import prohibitions. The three consolidated lawsuits therefore leave the judges with a precise legal question beneath all the political noise: whether the government’s use of Section 301 complied with the statutory requirements for imposing these particular duties. A three-judge panel, comprising appointees of Trump, Barack Obama and Joe Biden, is hearing the arguments, with a written ruling expected later.
For now, the tariff story remains unfinished. The administration has made tariffs a central instrument of its trade policy, while businesses, states and other challengers continue testing the boundaries of presidential tariff authority in court. Whether the forced-labor duties survive this latest legal examination could help define how far the White House can go when using trade laws to impose import taxes on trading partners.
