On 16 May 2022, the Government of Mexico introduced a decree, temporarily lifting import tariffs on over 20 staple food items and key inputs, including paddy rice, white maize grain and flour, wheat grain and flour, sliced bread, dried beans, milk, eggs, meat (pork, poultry and beef), vegetables (onions, potatoes, tomatoes and carrots) and fruits (oranges, lemons and apples). The measure is valid from 17 May 2022 for a period of one year and aims to contain increasing food inflation, which, in mid-May 2022, was up 11 percent compared to a year earlier. Most products on the tariff exemption list are imported primarily from the United States of America, where zero duties apply under a Free Trade Agreement. For example, in the 2019-2021 period, Mexico imported nearly 80 percent of wheat grain and 90 percent of paddy rice from the United States of America.

In addition, the Government of Mexico announced plans to build strategic reserves of maize (up to 1 million tonnes) and maintain the price guarantee scheme for maize, beans and rice for smallholder farmers.
