Whether manufactured or imported in Mexico, are subject to the relevant NOM standards and product labeling requirements.

Under Mexican law, NOM's licensee must be a Mexican company responsible for the quality, maintenance and reliability of the product.

If the product complies with the relevant regulatory requirements, a certificate is issued to the manufacturer or exporter of the Mexican representative to mark the NOM logo.
