US Opens USMCA Labor Complaint Against Puebla Auto Parts Plant
The United States invoked the USMCA Rapid Response Labor Mechanism against GLM Components Mexico in Puebla over allegations of union interference and retaliatory firings. Washington also suspended final customs processing for the plant's US-bound goods. Mexico has 10 days to accept the review and 45 days from October 8 to complete it.
The USMCA, which replaced NAFTA in 2020, includes a Rapid Response Labor Mechanism that allows a complaint against a single plant. USTR used Annex 31-A and directed Treasury to pause final customs handling for the Puebla facility’s US-bound goods. Mexico has 10 days to accept the review and 45 days from 8 October to complete it.
The petition reached a committee co-chaired by the US trade representative and labor secretary on 8 September. It came from Sindicato Regeneración Nacional, known as Morenas. The allegations concern interference with organizing and dismissals described as retaliation. USTR said the committee found enough credible evidence during its 30-day review. El Economista reported it is the mechanism’s 50th case.
The case could affect workers at the Puebla plant, their families, and local suppliers if it alters union representation or production. US buyers and importers may face delays or higher costs while customs processing is paused. A resolution could shape how Mexican auto-parts workers use the USMCA labor mechanism, though outcomes remain uncertain and no violation has been found.
