The Norma Oficial Mexicana (Official Mexican Standard) is the name of each of a series of official, compulsory standards and regulations for diverse activities in Mexico. They are more commonly referred to as NOM or normas.

Tequila

In the case of tequila

Tequila

Tequila is a spirit made from the blue agave plant, primarily in the area surrounding the city of Tequila, northwest of Guadalajara, and in the highlands of the western Mexican state of Jalisco....

, Mexico's Tequila Regulatory Council (CRT) regulates production NOMs. The NOM identifier means the tequila meets government standards - but this is not any guarantee of tequila's quality. However, without the NOM stamp of legitimacy, it is not guaranteed that the bottle contains tequila.

All 100% agave tequilas must have a NOM identifier on the bottle. The important laws since 1990 were NOM-006-SCFI-1993 and the later update NOM-006-SCFI-1994 and the most recent revision in late 2005, NOM-006-SCFI-2005.

The number after NOM is the distillery number, assigned by the government. NOM does not indicate the location of the distillery, merely the parent company or - in the case where a company leases space in a plant - the physical plant where the tequila was manufactured.
