WASHINGTON – Today, the U.S.-Mexico-Canada Agreement’s Interagency Labor Committee for Monitoring and Enforcement requested that the government of Mexico review an alleged denial of workers’ rights at Tubos de Acero de Mexico S.A., a manufacturer of seamless steel pipe located in Veracruz, Mexico.The U.S. Department of Labor and U.S. Trade Representative co-chair the Interagency Labor Committee. The request follows a May 14, 2025, petition filed by SINAIN, a Mexican union.Filed under the USMCA’s Rapid Response Mechanism, the petition alleges that the company is systematically denying SINAIN members their right to freedom of association and collective bargaining through acts of anti-union discrimination and interference with union activity.After the Interagency Labor Committee found sufficient and credible evidence supporting the petition’s allegations, the U.S. government submitted a request for Mexico to review the case using the RRM.The Mexican government has 10 days to decide whether to conduct a review and 45 days from today to investigate the claims and present its findings. TAMSA is one of the world’s leading producers of seamless steel tubes for the oil and gas, automobile, and construction industries. It exports to more than 50 countries, including the U.S.Learn more about the department’s international work.
