Mexico declared an emergency cement standard, citing 576 thousand tons a year from firms outside the regulatory framework, but it will not be enforceable until certifiers exist
On November 2, 2026, the Secretaría de Economía (Economy Ministry) published in the DOF (Mexico's federal gazette) the Norma Oficial Mexicana de Emergencia (emergency official Mexican standard) NOM-EM-023-SE-2026 for hydraulic cements, signed on October 26 and in force as of the following business day. Its recitals invoke article 31 of the Ley de Infraestructura de la Calidad (Quality Infrastructure Law), which reserves emergency standards for preventing imminent harm or mitigating existing harm, and state that uncertified cement produces low compressive strength and "high risk for people". The only figure for harm they quantify comes, according to the text itself, from "information obtained by the legally established cement industry": at least 576,000 tons a year in the hands of companies outside the regulatory framework, with an impact on the industry of 3,000 million pesos a year; they add that the amount may increase by another 2,800 million due to imported cement, based on "evidence" they do not identify, for about 5,800 million a year. The text declares it "essential to shield the formal market". The standard lasts six months, renewable only once, and its first transitory article declares it not enforceable "until there are sufficient Conformity Assessment Bodies, accredited and approved".
