25 US states sue the Trump administration over Section 301 tariffs imposed on more than 80 trading partners

Summary

Twenty-five US states filed suit on August 3 in the US Court of International Trade, asking the court to block the latest round of Trump administration Section 301 tariffs imposed on more than 80 trading partners after the president declared last month that those countries had failed an unspecified compliance standard. California's attorney general Rob Bonta, a lead plaintiff, said the tariffs are "hurting consumers and businesses." The states cited a recent US Supreme Court ruling in support of their challenge. The Section 301 authority, originally a trade-remedy statute, has been used by the administration to impose sweeping import duties without the congressional authorisation that courts have in some cases found is required for tariffs of this scope.

Why it matters

Twenty-five states filing jointly signals coordinated legal pressure from the state level on a second wave of broad tariffs. The US Court of International Trade has previously blocked or slowed executive tariff actions; a ruling in the states' favour could constrain the administration's use of Section 301 as a general trade lever against dozens of countries simultaneously.

What to watch

• Whether the US Court of International Trade grants an emergency injunction pausing the tariffs pending a ruling
• The full list of 25 plaintiff states and which of the targeted 80-plus trading partners joins the legal push independently
• How the administration responds and whether Congress moves to clarify Section 301 authority after the suit
