United States Announces Successful Resolution of Rapid Response Labor Mechanism Matter at ThyssenKrupp Springs & Stabilizers de México, S. de R.L. de C.V.

WASHINGTON - The United States today announced the successful resolution of the USMCA Rapid Response Labor Mechanism (RRM) matter at the ThyssenKrupp Springs & Stabilizers de México, S. de R.L. de C.V. (ThyssenKrupp) facility located in the city and state of San Luis Potosi, Mexico. The United States has resumed liquidation of tariffs on goods from the ThyssenKrupp facility, which manufactures automotive suspension components.

Actions taken by the facility to address the matter include:

• Reinstating two workers under the same terms and conditions held before they were dismissed in retaliation for union activity and issuing full payment of backpay and benefits;
• Signing an agreement with La Liga Sindical Obrera Mexicana, an independent union, that establishes a facility protocol; and
• Adopting, disseminating, and implementing a neutrality statement and company guidelines on freedom of association and collective bargaining, including a zero-tolerance policy for violations, and training all company personnel on the guidelines and neutrality commitments.

Actions taken by the Government of Mexico to address the matter include:

• Delivering in-person trainings for all company personnel on freedom of association and collective bargaining; and
• Monitoring the facility and engaging with the workers and the company throughout its review period.

Based on these measures, the United States Trade Representative, Ambassador Greer, has directed the Secretary of the Treasury to resume liquidation of unliquidated entries of goods from the facility.

Background

The United States Trade Representative and the Secretary of Labor co-chair the Interagency Labor Committee for Monitoring and Enforcement (ILC). On October 14, 2025, the ILC received an RRM petition from La Liga Sindical Obrera Mexicana, the United Steelworkers, and International Lawyers Assisting Workers Network. The petition alleges that ThyssenKrupp and an incumbent union at the facility had violated workers' rights by interfering in employees' union activity and retaliating against workers because of their attempts to organize an independent union at the facility, including through discriminatory firings or layoffs. The ILC reviews RRM petitions that it receives, and the accompanying information, within 30 days. The ILC determined that there was sufficient, credible evidence of a denial of rights enabling the good faith invocation of enforcement mechanisms.

As a result, on November 13, 2025, the United States Trade Representative submitted a request to Mexico to review the matter. Mexico accepted the request, conducted an investigation, and worked with ThyssenKrupp to provide remediation to dismissed workers and implement facility-wide measures aimed at safeguarding freedom of association and collective bargaining rights. The United States has reviewed the matter and concluded the situation to have been remediated.

As a result of the above actions taken by the facility and Mexico to resolve the action, the United States agrees that there is no ongoing denial of rights. Ambassador Greer's letter directing the Secretary of the Treasury to resume liquidation of unliquidated entries of goods from the facility is available here.
