USTR invokes USMCA labor mechanism against Newmont Mexico facility
On 12 June 2026, the US Trade Representative invoked the USMCA Rapid Response Labor Mechanism to challenge alleged denial of workers' rights at Newmont Minera Peñasquito in Zacatecas, Mexico, which produces gold, silver, lead, and zinc and imports auto parts. Following a petition from a Mexican labor union alleging unlawful dismissals and retaliation for union activity, the US has suspended liquidation of unliquidated entries from the facility and requested Mexico conduct a review within 45 days.

Facility and Products
Newmont Peñasquito produces gold, silver, lead, and zinc, and also imports auto parts into the United States. The facility's operations now fall under heightened trade scrutiny.
What triggered the RRM
On 13 May 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 Sindicato Nacional de Trabajadores Mineros, Metalúrgicos, Siderúrgicos y Similares de la República Mexicana (Los Mineros), a Mexican labor union.
The petition alleges that Newmont Peñasquito has violated workers' rights by retaliating against workers for engaging in union activity, including through unlawful dismissals.
After reviewing the petition within 30 days, the ILC determined there was sufficient, credible evidence of a denial of rights to invoke enforcement mechanisms in good faith.
Immediate enforcement actions
The US Trade Representative has:
- Suspended liquidation of unliquidated entries of goods from the Newmont Peñasquito facility
- Submitted a formal request to Mexico to review whether workers are being denied the right to freedom of association and collective bargaining
Mexico has 10 days to agree to conduct the review and, if it agrees, 45 days from 12 June 2026 to complete it.
What this means for shippers
If you source precious metals (gold, silver, lead, zinc—HS chapters 71, 74, 75, 76) or auto parts from Newmont Peñasquito or Mexican suppliers dependent on it, your shipments are now subject to entry suspension. Do not rely on normal liquidation timelines. Monitor Mexico's compliance within the 45-day window; if the review finds labor violations and Mexico does not remediate, tariffs or import restrictions on affected goods are likely. File with your customs broker immediately to assess your unliquidated-entry exposure and adjust sourcing or duty reserves now.
