The Normas Oficiales Mexicanas mark is a mandatory safety mark in Mexico to indicate that the product complies with the relevant NOM standards. The NOM mark applies to most products, including telecommunications and information technology equipment, household electrical appliances, lamps and other products that are potentially dangerous to health and safety. Products manufactured or imported locally in Mexico must comply with relevant NOM standards and product labeling requirements.
According to Mexican law, the licensee of NOM must be a Mexican company, responsible for the quality, maintenance and reliability of the product. The test report is issued by a laboratory accredited by SECOFI and audited by SECOFI, ANCE or NYCE. If the product meets the relevant regulatory requirements, a certificate is issued to the manufacturer or exporter's Mexican representative before the product can be marked with the NOM mark.
