On Tuesday, August 4th, 2026, twenty-five states, predominantly led by Democratic governments and spearheaded by Oregon, filed a lawsuit in the US Court of International Trade challenging the legality of former President Donald Trump’s new Section 301 tariffs.

The complaint argues that these tariffs, imposed under the pretext of combating forced labor, violate the requirements of Section 301 and are likely to harm the US economy and damage the country’s credibility with trading partners. This lawsuit marks the third legal challenge against the Section 301 tariffs.

Oregon has played a pivotal role in previous tariff litigation, including challenges to Trump’s IEEPA tariffs, which were invalidated by the Supreme Court in February 2026, and the more recent decision striking down Section 122 tariffs. The Oregon lawsuit was consolidated with one involving private small businesses harmed by the tariffs.

The current case raises arguments similar to those in earlier suits filed by the Liberty Justice Center on behalf of small businesses and by several firms including Learning Resources, Inc., a toy manufacturer whose case was part of the IEEPA litigation that led to a Supreme Court decision.

If successful, this lawsuit could block enforcement of the Section 301 tariffs nationwide. It is anticipated that the Court of International Trade may consolidate all three cases and issue a joint ruling.

Oregon Deputy Attorney General Ben Gutman and his legal team have been commended for their significant contributions to these legal efforts.
