US Tariffs on Mineral Fuels, Oils from Mexico — 10% (2026)

Mexico is a significant source of mineral fuels, oils imports into the United States, with approximately $779B in total bilateral trade.

Following the Supreme Court's landmark February 20, 2026 decision striking down IEEPA tariffs, imports of mineral fuels, oils from Mexico are now subject to a 10% tariff under Section 122 of the Trade Act of 1974, effective February 24, 2026.

This 10% rate has a built-in expiration: Section 122 limits presidential tariff authority to 150 days, meaning the tariff expires approximately July 24, 2026 without congressional renewal.

Mineral Fuels, Oils (HTS Chapter 27) carry an average MFN duty rate of 0.5% in addition to the Section 122 tariff. No additional Section 232 or Section 301 surcharges apply to most products in this category from Mexico.

Mexico is party to the USMCA, which may provide preferential or duty-free access for qualifying mineral fuels, oils. Importers should verify rules of origin requirements to take advantage of preferential rates.

Key products in HTS Chapter 27 imported from Mexico include Crude petroleum, Natural gas, Coal, Gasoline, Diesel fuel, and Jet fuel.
