Of products commercialized to consumers in Mexico must carry a Spanish-language label.
No exceptions — not even for your premium foreign brand. Importer data, net contents, country of origin, and applicable NOM. If they arrive without NOM labeling, they don't enter physical retail, don't comply with local marketplaces, and in sensitive categories, they don't even leave the customs fiscal warehouse. Labeling isn't cosmetic: it's the difference between having inventory and having inventory you can actually sell.
