We wanted to share a quick update regarding recent diesel price movements affecting transportation within Mexico and cross-border freight between Mexico and the United States. Over the past several weeks, diesel markets on both sides of the border have shown increased volatility, which continues to influence operating costs for carriers supporting Mexico-related trade lanes.

Because fuel represents a major cost component for long-haul and cross-border transportation, most Mexican and US carriers apply fuel surcharge programs that adjust periodically based on recognized diesel price benchmarks. These typically reference the US DOE/EIA national diesel index together with regional diesel pricing within Mexico. As those indexes move, the fuel surcharge percentage or per-mile adjustment applied to shipments is updated accordingly.

As a result, you may see periodic adjustments to the fuel surcharge portion of invoices related to Mexico-origin, Mexico-destination, or cross-border shipments. These adjustments reflect temporary market-driven changes tied directly to diesel pricing.

We will continue monitoring fuel market trends closely across both the US and Mexico and will keep customers informed of any meaningful developments. Our objective remains the same—maintaining transparency while ensuring reliable transportation capacity across Mexico and cross-border supply chains. Please reach out to your RIM representative if you have any further questions.
