Mexico Tariff Schedule 2026 (TIGIE): Duty Rates, USMCA Preferences & How to Look Up Codes

What is the TIGIE?

The TIGIE (Tarifa de la Ley de los Impuestos Generales de Importación y de Exportación) is Mexico's official tariff schedule. It assigns a tariff code (fracción arancelaria) and duty rate to every product that can be imported or exported. Think of it as Mexico's version of the U.S. HTS, but with important differences.

TIGIE vs HTS: Key differences

• First 6 digits: IDENTICAL — both based on the World Customs Organization's Harmonized System (HS)
• Digits 7-8: DIFFERENT — Mexico and the U.S. have their own national subdivisions
• Digits 9-10: DIFFERENT — statistical suffixes unique to each country
• Example: A laptop is 8471.30 worldwide, but 8471.30.01.00 in Mexico (TIGIE) vs 8471.30.0100 in the U.S. (HTS)
• Duty rates are completely different — Mexico's MFN rates are often higher than U.S. rates
• NOMs (Mexican product standards) are linked to TIGIE codes — HTS has no equivalent

Understanding Mexican duty rates

• MFN rate: The standard rate for imports from most countries. Ranges from 0% to 50%+.
• USMCA rate: 0% for qualifying U.S./Canadian-origin goods (most tariff lines).
• PROSEC rate: Reduced rates for manufacturers in specific sectors (e.g., automotive, electronics).
• The rate you pay depends on: the fracción arancelaria + the country of origin + whether you have a valid certificate of origin.

USMCA: How to get 0% tariffs

Most U.S.-manufactured goods qualify for 0% import duty under USMCA. But you must: verify that your product meets the specific rule of origin for its tariff heading, prepare a USMCA certificate of origin (self-certification is allowed), and present it to the Mexican customs broker at the time of import.

If you don't claim USMCA, you pay the full MFN rate. For many products, this means paying 15-25% in unnecessary tariffs.

Common tariff rates for U.S. exports to Mexico

• Auto parts (Ch. 87): 0% with USMCA, 5-20% MFN
• Electronics (Ch. 84-85): 0% with USMCA, 5-15% MFN
• Chemicals (Ch. 28-29): 0% with USMCA, 5-10% MFN
• Textiles (Ch. 50-63): 0% with USMCA, 15-35% MFN
• Food products (Ch. 01-24): varies widely, some subject to tariff-rate quotas
• Steel/aluminum (Ch. 72-73, 76): 0% with USMCA, 5-25% MFN + possible countervailing duties
