Iowa's congressional delegation is urging the Trump administration to consider the impact on farmers and consumers as it negotiates trade issues with Mexico following the termination of the U.S.-Mexico Tomato Suspension Agreement. Led by Sen. Chuck Grassley, the lawmakers warned that Mexico's antidumping investigation into U.S. pork, launched in December 2025, could threaten a key export market for Iowa producers. Mexico purchased more than $1.8 billion worth of Iowa pork in 2025, making it the industry's largest export destination. In a letter to administration officials, the lawmakers said the threat of retaliation from the number one export market creates a chilling effect on the pork industry that already faces headwinds domestically due to state regulations like California's Proposition 12. The delegation also noted tomato prices have risen nearly 7% since the agreement ended. The National Pork Producers Council backed the effort, calling for a resolution that preserves a stable U.S.-Mexico trading relationship.
