U.S. Trade Representative Jamieson Greer will travel to Mexico on April 20, 2026, for a new round of USMCA negotiations, as both countries review the trade agreement sector by sector, with agriculture and supply chain issues at the center of discussions.

The visit marks the second round of formal talks under the review process of the United States-Mexico-Canada Agreement (USMCA), following an initial session held in Washington in March. Mexican Economy Minister Marcelo Ebrard confirmed that negotiations will involve full-day meetings covering each economic sector individually, reflecting the broad scope of the agreement.

At the center of the agenda is the need to reassess trade flows, market access, and regulatory frameworks that directly impact North American agriculture. For U.S. producers, the USMCA remains a critical pillar for export stability, particularly in grains, livestock, and value-added agricultural products.

One of the most sensitive issues surrounding the talks is the recent halt of U.S. imports of Mexican livestock due to the screwworm pest, a development that has raised concerns across the livestock supply chain. While Mexican officials clarified that this issue does not fall directly under the authority of the Office of the U.S. Trade Representative, it is expected to be informally addressed during parallel meetings with agricultural stakeholders.

The livestock restriction highlights broader vulnerabilities in biosecurity, cross-border animal health protocols, and trade continuity, all of which are key concerns for producers and policymakers. Any prolonged disruption could affect beef supply chains, pricing dynamics, and feed demand, particularly in border states with strong integration between U.S. and Mexican operations.

Beyond livestock, the negotiations are expected to cover core agricultural sectors, including grains, oilseeds, and processed goods, as well as regulatory alignment and dispute resolution mechanisms. The review process comes at a time of increased volatility in commodity prices and global supply chains, adding pressure to maintain stable trade relationships within North America.

For U.S. agriculture, the outcome of these discussions could influence export competitiveness, input costs, and long-term investment decisions, particularly as policymakers evaluate the future of trade policy alongside the next farm bill cycle.

The renewed engagement between U.S. and Mexican officials underscores the strategic importance of the USMCA framework in sustaining regional agricultural integration, even as new challenges emerge in biosecurity, market access, and evolving global trade conditions.
