California Joins 25-State Coalition Lawsuit Challenging Federal Section 301 Tariffs

California has joined a coalition of 25 U.S. states in filing a lawsuit against the federal administration over its latest round of sweeping Section 301 tariffs. The action directly impacts California seafood importers, processors, and distributors facing new duties on imported seafood products.

The lawsuit targets new tariffs imposed on 60 global economies – 59 nations plus the European Union – which levy a 10% to 12.5% duty across a broad range of products, including major seafood categories.

Key Takeaways for CFSI Members

  • Scope of Tariffs: The duties affect nearly all goods – both raw materials and finished products – imported from the targeted 60 economies, directly squeezing seafood supply chain margins.
  • California’s Role: Attorney General Rob Bonta joined state attorneys general nationwide, arguing the administration bypassed statutory requirements and improperly used emergency authority.
  • Legal Argument: The lawsuit contends the Office of the U.S. Trade Representative (USTR) conducted rushed three-month investigations that failed to justify the broad trade restrictions or distinguish between compliant and non-compliant operations.

The Legal Challenge

The federal government justified the broad duties by citing failures among trading partners to enforce prohibitions on forced labor. However, state legal officers argue that the administration used labor concerns as a pretext for enacting indiscriminate, economy-wide tariffs without meeting Section 301 procedural standards.

Standard Section 301 investigations typically take eight to twelve months to establish evidence and analyze market impacts. The coalition’s complaint notes that USTR rushed these investigations in less than 90 days and failed to meaningfully evaluate comments submitted by industry stakeholders and foreign trade partners.

Furthermore, the suit highlights that the duties are applied blanket-style to both raw seafood inputs and finished goods, regardless of whether specific supply chains have established labor compliance standards.

“This is President Trump’s third attempt to illegally impose tariffs that would make life more expensive for American families and small businesses, and this is the third time we’re taking the Administration to court over this misuse of power.” – Rob Bonta, California Attorney General

Industry Impact & Next Steps

For California’s fisheries and seafood trade, these tariffs create additional friction at a time when businesses are already navigating supply chain volatility, inflation, and shifting regulatory demands. Imports vital to processing facilities, retail distribution, and foodservice channels face immediate cost pressure under the 10% to 12.5% rate structure.

The 25-state suit joins parallel litigation filed by the Liberty Justice Center seeking injunctive relief to halt tariff enforcement while the cases proceed through the federal court system.
