Mexico Tariff Rates 2026: Complete Guide for US Exporters

Mexico's tariff rates are set by the TIGIE (Tarifa de los Impuestos Generales de Importacion y Exportacion), the country's official tariff schedule. Rates range from 0% to 140% ad valorem, applied to the CIF customs value of imported goods. For US exporters, the most important fact is that virtually all goods originating in the United States enter Mexico at 0% duty under USMCA (the United States-Mexico-Canada Agreement), provided they meet the rules of origin and are accompanied by a valid certification of origin. For goods that do not qualify for USMCA, Mexico's MFN (Most Favored Nation) rates apply.

MFN Tariff Rates by Category

• Agricultural products: 0%–45%. Fresh fruits and vegetables typically 10–20%; processed foods 15–25%; dairy and poultry up to 45% (tariff-rate quotas may apply).
• Chemicals and pharmaceuticals: 0%–10%. Raw chemicals 0–3%; pharmaceutical ingredients 0–5%; finished medicines 5–10%.
• Textiles and apparel: 15%–35%. Yarn and fabric 10–15%; finished garments 25–35%. Plus potential countervailing duties for Asian origins.
• Footwear: 25%–35%. Among the highest-protected categories in Mexico's tariff schedule.
• Steel and metals: 0%–25%. Flat-rolled steel 15–25% (with active antidumping duties on Chinese origin); aluminum 5–15%.
• Automotive parts: 0%–10%. Under USMCA, most auto parts qualify for 0% if they meet regional value content rules (75% for vehicles).
• Electronics and machinery: 0%–15%. Computers and semiconductors generally 0–5%; consumer electronics 10–15%.
• Plastics and rubber: 3%–15%. Raw polymers 3–5%; finished plastic products 10–15%.

USMCA Preferences

USMCA eliminated tariffs on virtually all goods traded between the US, Mexico, and Canada that meet the agreement's rules of origin. To claim USMCA benefits, the exporter (or importer or producer) must prepare a certification of origin containing nine required data elements — no specific form is mandated, and the certification can be attached to the commercial invoice. The goods must satisfy product-specific rules of origin, which generally require that the product be wholly obtained in USMCA territory or undergo substantial transformation resulting in a tariff shift and/or meet a regional value content threshold.

Additional Charges Beyond the Tariff

• DTA (Customs Processing Fee): 0.8% for MFN imports; flat ~$20 USD for USMCA-qualifying goods.
• Import VAT (IVA): 16% on customs value + tariff + DTA. This is the largest charge for many imports.
• IEPS excise: applies to alcohol, tobacco, fuel, sugary drinks, and high-calorie foods.
• Countervailing duties: active on steel, footwear, and textiles from certain Asian origins — can add 20–66% to the tariff.
• Prevalidation fee (PRV): ~$13 USD per entry.

How to Look Up a Specific Rate

The official source is SIAVI (Sistema de Informacion Arancelaria Via Internet), operated by Mexico's Ministry of Economy. It allows searching by keyword, HS code, or tariff code, and displays the MFN rate, preferential rates under each FTA, non-tariff regulations, and applicable countervailing duties. VUCEM can also be used to verify permit and regulation requirements.
