The Trump administration has officially launched a sweeping series of “unfair trade” investigations into 16 major trading partners, signaling a aggressive push to restore the high-tariff regime recently dismantled by the U.S. Supreme Court. The probes, initiated on Wednesday under Section 301 of the Trade Act of 1974, target structural “excess capacity” in foreign manufacturing sectors that the White House claims is “untethered from market demand” and damaging to American industry.
U.S. Trade Representative (USTR) Jamieson Greer confirmed that the investigations cover a broad array of economies, including China, the European Union, India, Japan, South Korea, Mexico, Taiwan, Vietnam, and several Southeast Asian nations. The administration alleges that these partners utilize subsidies, suppressed wages, and non-commercial lending to flood the U.S. market with cheap goods, particularly in the automotive, semiconductor, and advanced manufacturing sectors.
“The policy remains the same; the tools may change depending on the vagaries of the courts,” Greer told reporters, emphasizing that Section 301 provides a more robust legal footing than the emergency powers struck down by the Supreme Court in February. The goal is to have new, permanent tariffs ready by July 24, 2026, when the current temporary 10% global surcharge is set to expire.
In a parallel move, the USTR also initiated a separate Section 301 probe into the use of forced labor, affecting over 60 countries. This investigation aims to expand existing bans—such as those on solar panels from China’s Xinjiang region, to a global scale, effectively creating a “human rights tariff” that could block billions of dollars in imports. Public hearings for the excess capacity probe are scheduled for May 5, with final recommendations expected by early summer.
This “Section 301” offensive marks a return to the high-stakes trade diplomacy that defined President Trump’s first term. By targeting structural trade surpluses and industrial overproduction, the administration is seeking to regain the leverage lost after the recent court ruling, forcing partners back to the negotiating table just as midterm election season begins to heat up.
