US invokes USMCA labor mechanism on Mexican latex balloon manufacturer
The US Trade Representative has invoked the Rapid Response Labor Mechanism (RRM) under the USMCA to review alleged workers' rights violations at Latex Occidental, S.A. de C.V. in Guadalajara, Mexico. The facility manufactures latex balloons and stands accused of denying workers freedom of association and collective bargaining rights, unlawfully changing union representation, and dismissing workers for union activity. The US has suspended liquidation of unliquidated entries of goods from the facility. Mexico has 10 days to agree to conduct a review and 45 days to complete it.

The Office of the United States Trade Representative (USTR) has invoked the Rapid Response Labor Mechanism (RRM) under the United States-Mexico-Canada Agreement (USMCA) to investigate alleged workers' rights violations at Latex Occidental, S.A. de C.V., a latex balloon manufacturer in Guadalajara, Jalisco, Mexico, as announced on April 16, 2026.
What Triggered the Action
On March 16, 2026, the Interagency Labor Committee for Monitoring and Enforcement (ILC)—co-chaired by the US Trade Representative and Secretary of Labor—received an RRM petition from the Secretary General of the Sindicato Único de Trabajadores de Látex Occidental. The petition alleges that the facility is violating workers' fundamental labor rights through multiple practices: unlawfully changing union representation and collective bargaining agreements as part of an improper transfer of workers to an affiliated company, and dismissing workers because of their union activity.
After a 30-day review, the ILC determined there is "sufficient, credible evidence of a denial of rights enabling the good faith invocation of enforcement mechanisms," prompting the USTR to formally request Mexico's review.
Immediate Consequences for Shipments
Effectively immediately, the United States has suspended liquidation of unliquidated entries of goods from the Latex Occidental facility. This means customs clearance and duty assessment for shipments from this manufacturer remain on hold pending the outcome of the labor review.
Mexico's Next Steps and Timeline
Mexico has been given a compressed timeline under the RRM:
- 10 days to agree to conduct the review
- 45 days from April 16, 2026 to complete the review if it agrees
This rapid timeline reflects the USMCA's commitment to swift enforcement of labor standards across North American trade.
Impact on Trade
The suspension of liquidation affects all unliquidated entries of latex balloons and related products from this facility. Exporters and freight forwarders managing shipments from Latex Occidental should anticipate delays in customs clearance and duty assessment until Mexico completes its review or the USTR receives assurances that workers' rights are being protected.
Previously invoked RRM cases are available in the USTR's public record, providing context for how these mechanisms have been applied in past labor disputes.
What this means for shippers
Shipments from facilities subject to labor investigations face customs delays and potential entry suspension. Understanding the USMCA labor framework and its enforcement mechanisms is critical for managing supply chains and landed costs involving Mexican suppliers.
