USMCA 2026 Review: What the 10% Tariff Means for Cross-Border Fuel Trade

The USMCA joint review began March 18, 2026 and must conclude by July 2026. Under Article 34.7, all three parties must confirm whether to extend the agreement to 2042. If any party declines, annual reviews follow until the agreement sunsets in 2036. Meanwhile, the Supreme Court struck down the 25% IEEPA tariff on February 20 but upheld a 10% Section 122 tariff through July 24, 2026.

USMCA-qualifying goods are exempt from the 10% Section 122 tariff. For petroleum products under HTS 2709-2710, proving USMCA origin requires a valid Certificate of Origin (CO) linked to each customs entry. For a cross-border fuel distributor moving 10,000 barrels per day, failure to qualify means approximately $300,000 per month in additional tariff costs.

USMCA utilization rates jumped from approximately 45% in early 2025 to 89% by November 2025 as companies scrambled to qualify. For fuel traders, this means your competitors are already filing COs. Those who don't are paying 10% more per barrel and passing that cost to customers — or absorbing it from already thin margins.

The US Trade Representative is pressing Mexico on: (1) Non-discriminatory treatment for US fuel distributors, (2) Transparent permit processing by CNE, (3) Market access guarantees for US refined products, (4) Removal of PEMEX preferential treatment. The outcome will shape cross-border fuel trade rules for years.

Cantarell OS manages the full cross-border documentation chain: pedimento generation with automatic duty calculation (IEPS, IVA, DTA), border crossing tracking at all 5 major ports (Laredo, El Paso, Brownsville, McAllen, Nogales), and Certificate of Origin management linked to each shipment. Prove USMCA compliance automatically and avoid the 10% tariff.
