US Wins Trade Dispute Over Mexico's Genetically Modified Corn Restrictions

A USMCA panel ruled Mexico's measures violated trade agreements, ensuring continued market access for American corn exports.

The US successfully challenged Mexico's restrictions on genetically engineered (GE) corn under the USMCA, prevailing on all seven legal claims.
The trade panel found Mexico's measures were not based on scientific evidence and violated USMCA chapters on sanitary measures and market access.
Mexico's proposed ban targeted GE corn for human consumption and aimed to phase out its use in animal feed, raising concerns from US exporters.
The ruling protects the $4.8 billion US corn export market to Mexico, the largest importer of American yellow corn primarily used as livestock feed.
Mexico's government disagreed with the ruling but stated it would comply, citing its commitment to public health and Indigenous community rights.
