Mexico imposes anti-dumping duties on Chinese and Vietnamese steel

The Ministry of Economy published on September 3, 2026, in the Official Gazette of the Federation (number 240/2026) the final resolution of the antidumping administrative investigation procedure that imposes definitive countervailing duties on imports of hot-rolled steels originating from the People’s Republic of China and the Socialist Republic of Vietnam, regardless of the country of provenance. The measure, signed on August 27, 2026, by Secretary Marcelo Luis Ebrard Casaubon, enters into force the day following its publication and affects importers, the national steel industry, and the prices of manufacturing inputs.

Background of the procedure

The investigation was filed under case file AD_34-24 of the International Trade Practices Unit following the request submitted on November 19, 2024, by Ternium México, S.A. de C.V., the petitioner. The initiation resolution was published on March 3, 2025, with an investigated period from September 1, 2023, to August 31, 2024, and a damage analysis period from September 1, 2021, to August 31, 2024; the preliminary resolution, which established provisional duties, was published on March 23, 2026.

The domestic production branch was composed of Ternium, which represented 82% of production in the investigated period and 84% in the analyzed period, with the support of ArcelorMittal and Grupo Acerero. The authority determined that the investigated imports were carried out with price discrimination margins exceeding the de minimis level and caused a threat of injury, with an average price 15% below the national selling price and 31% lower than those from other origins.

Definitive countervailing duties

The duties, expressed in dollars per kilogram, are set individually by company:

• Shanghai Meishan Iron: 0.3087 dollars per kilogram.
• Wuhan Iron: 0.3050 dollars per kilogram.
• Other appearing Chinese producing exporters not selected: 0.3070 dollars per kilogram.
• Other Chinese exporters: 0.3087 dollars per kilogram.
• Hoa Phat Dung Quat: 0.2855 dollars per kilogram.
• Formosa Ha Tinh: 0.2719 dollars per kilogram.
• Other Vietnamese exporters: 0.2855 dollars per kilogram.

The duties apply to goods entering under the TIGIE tariff headings 7208.10.03, 7208.25.02, 7208.26.01, 7208.27.01, 7208.36.01, 7208.37.01, 7208.38.01, 7208.39.01, 7208.40.02, 7208.51.04, 7208.52.01, 7208.53.01, 7208.54.01, 7208.90.99, 7211.13.01, 7211.14.91, 7211.19.99, 7225.30.91, 7225.40.91, and 7226.91.07, as well as those entering under the Eighth Rule via headings 9802.00.01 to 9802.00.21.

Positions of the parties

Among the appearing exporters are Baoshan Iron, Baosteel Zhanjiang, China Steel and Nippon Steel Vietnam, Hoa Phat Steel, Jiangsu Tiangong Tools, Shougang Jingtang United, and Shougang Qian’an Iron, while the importers Truper, Marubeni-Itochu Steel México, Conduit, and Gonher de México alleged that the measure would increase the cost of inputs and affect competitiveness. The authority dismissed the arguments of “double remedy” and overprotection, considering that tariffs and countervailing duties pursue different objectives and that the merchandise was imported from 47 additional countries during the analyzed period.

The resolution, which will be notified to the ANAM and the Tax Administration Service, represents a relevant precedent for the Mexican steel industry and for manufacturers who depend on hot-rolled steel as an input, by rearranging the conditions of competition against Asian imports.
