Four U.S. grain and seed organizations accused Mexico of using ambiguous regulations to evade a USMCA panel ruling that required the removal of restrictions on genetically modified corn imports. They submitted comments to the U.S. Trade Representative, raising concerns about Mexico’s constitutional reform and proposed environmental review powers.
If the challenged rules preserve restrictions, they could constrain U.S. corn access to Mexico; if the panel ruling is implemented, import access could improve. The dispute creates uncertainty for cross-border corn trade, but the article reports allegations rather than a new restriction or ruling.
After 480 past neutral trade events, Corn moved a median +0.2% over 5 sessions (54% higher; middle half -1.1% to +1.6%), and +0.7% over 20.
