U.S. tariff probe keeps importers uneasy
The U.S. Trade Representative opened Section 301 investigations into “structural excess capacity” across 16 economies, a move that keeps importers in limbo about future tariffs. Public comments were due April 15 and a public hearing is scheduled for April 28, while businesses importing bicycles, European cheese and infant sleeping bags warned new duties could inflict lasting harm.

The Office of the United States Trade Representative has opened a new Section 301 tariff probe into “structural excess capacity” in 16 economies, leaving importers waiting to see which goods could face new duties. (ustr.gov) The investigations began on March 11, 2026 and cover China, the European Union, Singapore, Switzerland, Norway, Indonesia, Malaysia, Cambodia, Thailand, Korea, Vietnam, Taiwan, Bangladesh, Mexico, Japan and India. The Federal Register notice says written comments and requests to testify were due by April 15 at 11:59 p.m. Eastern time. (federalregister.gov) The same notice schedules a public hearing for May 5, 2026 at the United States International Trade Commission, with sessions continuing through May 8 if needed. The agency has not yet announced any tariff rates or product list. (federalregister.gov) Section 301 is the trade law the United States uses to investigate foreign government practices it says are “unreasonable or discriminatory” and that burden United States commerce. The trade representative can self-initiate a case and later recommend tariffs or other restrictions. (ustr.gov) In this case, the Trump administration says some trading partners built manufacturing capacity beyond what their own markets can absorb, then pushed the surplus abroad. A USTR fact sheet points to sectors including steel, aluminum, autos, batteries, chemicals, electronics, semiconductors, ships, solar modules and processed food and beverages. (ustr.gov) The timing matters because the White House has been looking for other tariff tools after the Supreme Court blocked Trump’s broader emergency-power tariffs earlier this year. A federal trade court is still weighing the legality of the administration’s replacement 10 percent global tariff under a different 1974 law, Section 122. (politico.com) That overlap has kept importers focused on Section 301, which can support more targeted tariffs that last longer than the 150-day Section 122 duties now being challenged in court. Lawyers for businesses and Democratic-led states told the Court of International Trade that the Section 122 tariffs are set to expire in July unless Congress extends them. (politico.com) Businesses that import consumer goods are already trying to shape the record before any tariff list appears. USA Today reported that importers of European cheese, infant sleeping bags and ceramics warned that new duties would raise costs and damage small companies that cannot quickly replace foreign suppliers. (usatoday.com) The bicycle industry has been making a similar argument in a separate Section 301 fight tied to China. PeopleForBikes says existing product exclusions are due to expire on December 31 and warned that, without an extension from the trade representative, bicycle businesses remain exposed to higher import costs. (peopleforbikes.org) For now, the new probe has moved from announcement to evidence-gathering, not decision. The next public marker is the May 5 hearing, when importers, trade groups and other witnesses will try to shape whether this investigation ends in another round of tariffs. (ustr.gov)
