Antidumping and countervailing duties (cuotas compensatorias) are additional duties Mexico imposes on certain products from certain countries when they are found to enter at dumped or subsidized prices. They can be higher than the normal duty and are paid on top of IGI and VAT. If your product carries one and you do not know it when you buy, the cost of the import can change completely.
How they work
- They are set by Mexico’s Ministry of Economy after an investigation, for a specific product (identified by its tariff classification and description) and a specific country of origin.
- They can be a percentage of value or a fixed amount per unit (per kilo, per pair, per piece).
- They apply by country of origin, not the country of shipment: Chinese goods routed through another country are still of Chinese origin.
- They are reviewed periodically and can be removed, changed or extended.
Where they are most common
Historically, several steel products, certain chemicals, footwear, textiles and some consumer goods, mostly of Asian origin. The list changes: check it for each tariff line and origin before every purchase.
How to prove a different origin
- If your goods come from a country without an antidumping duty, you must be able to prove it with the origin documentation required by the non-preferential rules of origin.
- Without proof of origin, the authorities can presume the goods come from the country with the duty and charge it.
- Trying to avoid it by changing the shipping country or making minor changes to the product can be investigated as circumvention, with penalties.
IMMEX and antidumping duties
Having IMMEX does not automatically remove antidumping duties: check whether they apply to your inputs even on temporary imports. See IMMEX vs PROSEC.
Recent changes (September 2026)
- Hot-rolled steel from China and Vietnam: definitive antidumping duty (final ruling published in Mexico’s Official Gazette, the DOF, on September 3, 2026). It also covers temporary imports and bonded storage.
- Hollow aluminum profiles from the United States and China: definitive antidumping duty (DOF, September 4, 2026). A trade-agreement origin such as the United States does not exempt goods from an antidumping duty.
- Under investigation, with a preliminary ruling: tinted float glass and textile-reinforced PVC tarpaulins, both from China.
The amount depends on the product and the exporter. We confirm it against the ruling in force before you buy.
Review before you buy
Before you close a purchase, we check the tariff classification, the origin and whether an antidumping duty is in force, and estimate the total cost. Try our tax calculator, which includes an antidumping field. For imports from Asia, see importing from China into Mexico.
