A USMCA trade panel ruled in December 2024 against Mexico's restrictions on GM corn in the CUSMA dispute brought by the US. The case centered on Mexico's 2023 decrees limiting GM corn for tortillas and feed, which the panel found violated sanitary rules.
The ruling sets a precedent that may force Mexico to keep importing US GM corn, supporting long-term US corn export demand, while the trade dispute adds headline risk.
