Key Takeaways:

  • U.S.-Mexico trade reached $74 billion in May 2025, a 2.64% increase year-over-year, driven by nearshoring and regional supply chain adjustments.
  • Laredo, Texas, remains the busiest trade gateway, processing over $27.6 billion in May, largely via truck transport.
  • Potential future tariffs, including a proposed 30% tariff on all Mexican imports and a reinstated 17.56% tariff on fresh tomatoes, threaten this growth and introduce market uncertainty.
  • Despite tariff risks, nearshoring continues to boost cross-border freight, highlighting the importance of monitoring regulatory changes and maintaining strong cross-border relationships.

Trade between the U.S. and Mexico continues to surge, fueled in large part by nearshoring trends and tighter regional supply chains. In May, U.S.-Mexico trade volumes reached an impressive $74 billion, according to the latest data from the U.S. Census Bureau. That figure marks a 2.64% increase from the same time last year, with key growth areas in automotive parts, computers, agricultural products, and electronics.

Laredo, Texas, once again stood out as the busiest international gateway for trade, processing over $27.6 billion in total imports and exports. Much of that movement was truck-based, with the port recording nearly 300,000 commercial crossings in May alone. This sustained growth signals continued opportunity, but looming trade tensions could complicate the road ahead.

The Trump Administration recently announced a proposal to reinstate broad tariffs on Mexican imports if re-elected, calling for a 30% tariff on all goods coming from Mexico. Tariffs at this scale would likely introduce volatility into what has recently been one of the most stable growth areas for freight.

A fresh ruling by the U.S. Commerce Department in late June reinstated a 17.56% tariff on Mexican fresh tomatoes, a staple in U.S. grocery imports. Produce industry experts warn that prices could jump 30% or more in the coming months, especially as buyers seek alternative sources. Any cost shift like this could ripple across reefer capacity and affect seasonal planning for brokers that move perishable goods.

Despite this uncertainty, nearshoring remains a long-term force reshaping North American freight. As more companies relocate manufacturing from Asia to Mexico, cross-border freight continues to solidify its importance. But the prospect of sweeping tariffs injects a new layer of unpredictability that supply chains must be prepared for.

With U.S.-Mexico trade showing no signs of slowing, watching regulatory developments while reinforcing their relationships on both sides of the border will become paramount.
