Examples


Tequila

In the case of tequila, 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 revised in late 2005 NOM-006-SCFI-2005 and the most recent revision in 2012.NOM-006-SCFI-2012
/ref> 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.
