Also known as: Most Favored Nation tariff, MFN rate, General tariff rate
The maximum tariff rate a WTO member country applies to imports from any other member, guaranteeing equal treatment without discrimination among trading partners.
The Most Favored Nation (MFN) tariff is the fundamental WTO principle establishing that any tariff advantage granted to one member must automatically extend to all other members. In practice, it is the general tariff rate Mexico applies to imports from countries without an active free trade agreement. Exceptions to this principle include preferential trade agreements and free trade zones.
