Mexico’s National Customs Agency (ANAM) has clarified how customs authorities will handle goods that fail to comply with Mexican Official Standards (Normas Oficiales Mexicanas, or NOMs) for commercial information at the border. In Press Release 74/2026, dated 8 September 2026, ANAM issued an orienting criterion for its administrative units, drawing an important distinction between outright non-compliance and the presentation of omitted or inaccurate data.
The clarification stems from Mexico’s broader Customs Law (Ley Aduanera) reform, published in the Official Journal of the Federation (DOF) on 19 November 2025 and in force since 1 January 2026, which significantly hardened the consequences of NOM commercial-information failures at customs.
