25 States Sue Trump Administration to Block New Tariffs on Trading Partners

A coalition of 25 Democratic-led states sued the Trump administration on August 4, 2026, in the U.S. Court of International Trade. The lawsuit seeks to block new tariffs ranging from 10% to 12.5% on 60 trading partners, alleging the administration used forced-labor concerns as a pretext to reinstate import taxes previously ruled illegal.

The legal challenge, led by New York and Oregon, targets a sweeping set of levies that affect 59 countries and the European Union. According to the plaintiffs, these tariffs account for 99.4% of all U.S. imports. The states are asking the court to halt the measures, declare them unlawful, and order refunds for duties already paid.

Section 301 and the Forced Labor Pretext

The administration implemented these new duties under Section 301 of the Trade Act of 1974, which allows the president to sanction countries engaging in unfair trade practices.

The transition between these laws has drawn scrutiny. However, he pointed out that Section 301 has a history of durability, having been used by Trump during his first term to target Chinese imports.

Economic Stakes for Families and Businesses

Beyond the legal theory, the states argue that the tariffs act as a regressive tax. Governor Kathy Hochul of New York highlighted that the measures drive up the cost of groceries, household essentials, building materials, and countless everyday goods for her constituents.

The lawsuit is not the only challenge. The Liberty Justice Center has filed a separate suit on behalf of two small businesses, arguing that the administration failed to establish a specific case against each economy or explain how the tariffs would actually eliminate forced labor practices.

White House Defense and the USTR Investigation

The White House maintains that the tariffs are a lawful tool to protect American workers. Spokesman Kush Desai asserted that a foreign country’s failure to enforce prohibitions on forced labor is unreasonable and burdens U.S. commerce.

25 states sue over Trump's newest tariffs, saying Supreme Court already ruled them illegal

The coalition of 25 states—including California, Massachusetts, and Washington, along with the governors of Kentucky and Pennsylvania—will now wait for the U.S. Court of International Trade to determine if the administration stayed within the guardrails of the 1974 Trade Act or if the “forced labor” justification was indeed a legal workaround to bypass the Supreme Court’s February ruling.
