US-Mexico Trade Climbs as Laredo Corridor Expands Capacity

US-Mexico freight trade reached US$872.8 billion in 2025, with the Laredo-Nuevo Laredo corridor consolidating its role as the backbone of North American supply chains. As Port Laredo posted record trade volumes and Mexico’s surplus with the US narrowed, the expansion of Nuevo Laredo III is emerging as a key infrastructure project to sustain nearshoring-driven growth and reduce border bottlenecks.

US-Mexico freight trade reached US$872.8 billion in 2025, up 3.9% from 2024, confirming Mexico’s position as the United States’ top trade partner in North American surface freight and reinforcing the strategic weight of the border logistics corridor linking Texas and northern Mexico. 

According to the US Bureau of Transportation Statistics (BTS), trucks continued to dominate bilateral freight flows, carrying 73.6% of total US-Mexico freight by value, while rail accounted for a further 12.7%. The figures highlight how deeply integrated manufacturing and distribution networks on both sides of the border remain dependent on road-based trade.

At the center of this dynamic is Port Laredo, which posted US$353.94 billion in international trade in 2025, an increase of US$14.94 billion from the previous year. The port described itself as the Western Hemisphere’s leading land port, a status supported by the scale of its throughput and by its role as the primary gateway for automotive parts, electronics, machinery, consumer goods and energy-related cargo moving between the United States and Mexico. More than 97% of the port’s trade is linked to Mexico, underlining the extent to which Laredo’s performance is inseparable from the health of the bilateral commercial relationship.

The broader BTS report helps explain why Laredo remains so central. In 2025, freight between the United States and Mexico rose while freight between the United States and Canada fell to US$712.8 billion, meaning Mexico widened its lead as the United States’ largest land-trade partner by freight value. BTS also notes that surface transportation remains the backbone of this exchange, reflecting the operational structure of North American regionalization, short-haul and medium-haul cross-border trucking, integrated just-in-time delivery systems, and manufacturing platforms that spread production across multiple jurisdictions before final assembly or sale.

This is especially visible in the commodity profile moving through the Laredo corridor. Port Laredo and related trade dashboards have consistently highlighted high-value manufactured goods such as computers, motor vehicle parts, cell phones and related electronics, passenger vehicles, and commercial vehicles among the leading products crossing the border.

However, headline trade growth does not mean the relationship is expanding evenly in Mexico’s favor. New January 2026 data showed Mexico’s trade surplus with the United States narrowing sharply.  The US Census Bureau data reports that Mexico’s surplus with the United States fell to US$10.93 billion in January, the lowest level for that month in 17 years, as US exports to Mexico rose 13.1%, reports MBN. That shift suggests that while total bilateral trade remains robust, the composition of the exchange is evolving, with stronger US sales into Mexico offsetting some of the gains from Mexican exports northbound.

That narrowing surplus may reflect a deeper structural change rather than a temporary fluctuation. As Mexico continues to attract industrial investment tied to nearshoring, the country is also importing more capital goods, intermediate goods, machinery, and technology needed to expand production capacity. In that sense, stronger US exports to Mexico can be read as a sign of industrial deepening rather than weakness alone. 

Rising trade volumes through Laredo and Nuevo Laredo are creating renewed pressure on customs processing, bridge capacity, cargo lane availability, and local freight networks. In response, Tamaulipas is moving forward with the expansion of the Nuevo Laredo III International Bridge, also known as the World Trade Bridge, a project intended to accelerate freight crossings, reduce logistics costs, and strengthen the state’s role as a key trade platform for Mexico-US commerce. MBN reported that the expansion will add capacity, improve customs operations, and reinforce the crossing’s role in supporting nearshoring-driven cargo growth.

The importance of that project goes beyond local traffic management. The Nuevo Laredo III bridge is one of the most critical cargo crossings on the border, and any expansion there has implications for national competitiveness. If cargo can move faster and more predictably through the corridor, manufacturers on both sides benefit from lower dwell times, fewer delays, reduced fuel and warehousing costs, and greater certainty in delivery schedules. For industries built around lean inventories and fast turnaround times, those efficiencies can shape location decisions and future investment.
