Mexico opened an expiry review of its 40.25% anti-dumping duty on ferrosilicomanganese from India on Oct. 8, 2026, keeping the duty in force while the review runs.<\/p>\n
Mexico’s Ministry of Economy opened a review on Oct. 8, 2026 of its 40.25% anti-dumping duty on ferrosilicomanganese from India, and the duty stays in force while the review runs1<\/a><\/sup>.<\/p>\n The Ministry of Economy’s resolution, published in the Diario Oficial de la Federaci\u00f3n (DOF), Mexico’s official gazette, starts what Mexico calls an "examen de vigencia"1<\/a><\/sup>. This is an expiry review, also called a sunset review: a check on whether a duty should end after five years or be kept.<\/p>\n In short, Mexico will not let the duty lapse on schedule while it studies the case. Every shipment of this steelmaking alloy from India still pays the extra 40.25% at the Mexican border until the review ends.<\/p>\n Ferrosilicomanganese is a metal alloy of manganese, silicon and iron, sold in lumps of different sizes or as a powder1<\/a><\/sup>. It is also traded under the name silicomanganese. It usually contains small amounts of carbon, phosphorus and sulphur.<\/p>\n The resolution describes a typical grade1<\/a><\/sup>. It has about 65% manganese<\/strong>, more than 14% silicon, 2% to 2.5% carbon, no more than 0.3% phosphorus and at most 0.04% to 0.05% sulphur.<\/p>\n Steel mills are the main buyers. The ministry calls the alloy an essential raw material for making steel1<\/a><\/sup>. It removes oxygen and sulphur from molten steel in structural and special steels. Smaller amounts go into welding products and very clean, fine-grained steels.<\/p>\n The alloy ends up in many common steel goods1<\/a><\/sup>. These include reinforcing bar, wire rod, slabs, plate, sheet, structural shapes, seamless tubes, machine-grade bars, cast steel parts and welding electrodes.<\/p>\n Mexico first imposed the duty in a final anti-dumping resolution published in the DOF on Oct. 18, 20161<\/a><\/sup>. An anti-dumping duty<\/strong> is an extra import tax on goods sold abroad below their normal price. Mexico’s law calls it a "cuota compensatoria", a compensatory duty.<\/p>\n The 2016 decision set a definitive duty of 40.25%<\/strong> on ferrosilicomanganese from India2<\/a><\/sup>. It applies whatever country the goods are shipped from. It covers both permanent imports and temporary imports, which enter Mexico to be processed and exported again.<\/p>\n A first expiry review ended with a final resolution published on April 3, 20231<\/a><\/sup>. In it, the ministry kept the 40.25% duty for five more years, counted from Oct. 19, 2021.<\/p>\n Under Mexican trade law and the World Trade Organization’s anti-dumping agreement, a definitive duty ends after five years1<\/a><\/sup>. It survives only if the ministry starts an expiry review before the five years are up. The review must follow a request from one or more Mexican producers.<\/p>\n On Oct. 16, 2025, the ministry published a notice listing duties due to expire1<\/a><\/sup>. Ferrosilicomanganese was on the list. The notice gave Oct. 18, 2026 as the last day<\/strong> of the duty. Producers had until Sept. 10, 2026 to ask in writing for a review.<\/p>\n Compa\u00f1\u00eda Minera Autl\u00e1n, a Mexican mining company, filed that request on Sept. 9, 20261<\/a><\/sup>. It mines metals and minerals and makes ferrosilicomanganese. It proved it is a Mexican producer with its own sales invoices. The ministry found the request was made on time and in the correct form, so it opened the review.<\/p>\n Minera Autl\u00e1n also asked for the first review, on Sept. 10, 20212<\/a><\/sup>. That review was opened in the DOF on Oct. 5, 2021.<\/p>\n The review covers ferrosilicomanganese that originates in India, whatever the country it ships from1<\/a><\/sup>. It names two entry routes in Mexico’s tariff, the TIGIE:<\/p>\nWhat is ferrosilicomanganese and who uses it?<\/h2>\n
