The United States has announced the resolution of a labor rights case at Superior Industries de Mexico, S. de R.L. de C.V., a facility in Chihuahua, Mexico that manufactures aluminum wheels for light vehicles. The case was handled under the USMCA Rapid Response Labor Mechanism (RRM), which aims to ensure fair labor practices in trade between the U.S., Mexico, and Canada.
According to officials, the resolution allows the U.S. to resume liquidation of tariffs on goods from Superior Industries after determining that issues regarding workers’ rights had been addressed.
“The Department of Labor’s Bureau of International Labor Affairs, Office of the U.S. Trade Representative, and the Mexican government cooperated closely to provide remedies for workers’ claims,” stated authorities involved in the process.
Actions taken by Superior Industries included reinstating seven workers who were previously dismissed for union activity and providing them with full back pay and benefits. Four other workers received severance packages after choosing not to return. The company also committed to reinstate or offer severance packages to two additional employees based on their preferences.
Superior Industries adopted new guidelines on freedom of association and collective bargaining, implemented a zero-tolerance policy for violations, trained all personnel on these commitments, and withdrew a complaint against workers who participated in work stoppages.
The Mexican government contributed by delivering training sessions on labor rights for all company staff and monitoring compliance at the facility during its review period.
The RRM was established under the first Trump Administration as part of efforts to prevent unfair competition through labor law violations in Mexico. The Interagency Labor Committee for Monitoring and Enforcement (ILC), co-chaired by the United States Trade Representative and Secretary of Labor, reviewed an RRM petition submitted by CATEM—a Mexican labor union—on May 5, 2025. The petition alleged intimidation tactics used by Superior Industries management against union supporters.
After reviewing evidence within 30 days as required by protocol, the ILC found credible grounds for enforcement action. On June 4, 2025, a formal request was made to Mexico for review; authorities there confirmed that necessary remedial steps had been taken at Superior Industries regarding freedom of association and collective bargaining.
With both countries agreeing that no ongoing denial of rights remains at the facility, Ambassador Greer authorized resumption of normal tariff processing on goods from Superior Industries.
