US Labeling Requirements for Mezcal

Mezcal sold in the United States must satisfy two distinct regulatory regimes simultaneously: Mexican certification requirements administered by the Consejo Regulador del Mezcal (CRM) and US federal labeling law enforced by the Alcohol and Tobacco Tax and Trade Bureau (TTB). A bottle that clears customs but misses a single required TTB statement cannot legally hit a retail shelf. Understanding where those two systems overlap — and where they diverge — is the practical heart of getting mezcal to American consumers.

Definition and scope

The TTB governs distilled spirits labeling under the Federal Alcohol Administration Act (FAA Act) and its implementing regulations at 27 CFR Part 5. For imported spirits bearing a geographic designation, there is an additional layer: the spirit must conform to the standards of its country of origin. Mezcal, which carries a Denomination of Origin protected under Mexican law and recognized by the United States through trade agreements, must therefore meet both TTB format rules and CRM category standards before a Certificate of Label Approval (COLA) can be issued.

The TTB's COLA system is the gatekeeper. No importer may sell a labeled spirits product in interstate commerce without first obtaining COLA approval through the TTB's Permits Online portal. As of 2023, the TTB processes tens of thousands of COLA applications annually across all spirits categories.

How it works

A COLA application for mezcal requires the importer — not the Mexican producer — to submit label mock-ups demonstrating compliance with 27 CFR Part 5. The TTB evaluates each mandatory label element:

Brand name — must appear prominently and cannot be misleading about origin or composition.
Class and type designation — "Mezcal" must appear as the class designation; subclassifications such as joven, reposado, or añejo are permitted if accurate.
Alcohol content — expressed as "X% alc/vol" or equivalent; mezcal typically ranges from 36% to 55% alc/vol, and the stated figure must match the actual product within TTB tolerance thresholds.
Net contents — volume in metric units (e.g., 750 mL).
Country of origin — "Product of Mexico" is required for all mezcal entering the US market.
Name and address of the responsible party — the US importer of record must be listed.
Government warning statement — the Surgeon General's warning mandated by the Alcoholic Beverage Labeling Act of 1988 must appear in a minimum 2mm type size (TTB, Government Warning Requirements).

The CRM's own certification number — a series of digits identifying the batch and certifying producer — typically appears on mezcal labels as well, though its placement is a Mexican regulatory requirement rather than a TTB mandate. Bottles certified under the Consejo Regulador del Mezcal system carry this number as proof of denomination compliance.

Common scenarios

Three labeling situations come up with regularity in the mezcal import channel.

Agave species disclosure. Mexican regulation NOM-070-SCFI-2016 requires the agave species to appear on the label. The TTB does not independently require this, but because the COLA must be consistent with the product's Mexican certification, the species name typically carries through to US labels automatically. Bottles featuring agave varieties used in mezcal other than Agave angustifolia (espadín) — such as Agave karwinskii or Agave potatorum — must list the correct botanical name on the Mexican certificate, which then appears on the US label.

Category designations: artisanal vs. ancestral. NOM-070 created three production categories — industrial, artisanal, and ancestral — with artisanal vs. ancestral vs. industrial mezcal classifications determined by equipment and technique. A US COLA application for a bottle labeled "Mezcal Ancestral" must be supported by CRM certification confirming that classification. Mismatched claims between the CRM certificate and the US label are a common cause of COLA rejection.

ABV rounding and tolerance. TTB regulations permit a tolerance of ±0.3% alc/vol between the stated and actual alcohol content for spirits above 24% alc/vol (27 CFR § 5.37). High-proof mezcals, some of which reach 55% alc/vol or above, require precise laboratory verification before the label figure is locked in.

Decision boundaries

The clearest dividing line in US mezcal labeling is between what the TTB mandates and what the CRM mandates — and neither agency accepts the other's approval as a substitute for its own.

A second important boundary runs between understanding mezcal labels as a consumer exercise and the regulatory compliance process as an importer obligation. The information a drinker reads on a bottle — terroir notes, village of origin, maestro's name — is largely optional under both US and Mexican law. What is not optional is the seven-element TTB list above, plus the CRM certification number on the Mexican side.

The mezcal-importation-us-regulations framework adds customs documentation requirements on top of label approval, meaning COLA issuance and customs clearance are sequential steps, not interchangeable ones. A COLA can be approved weeks before a shipment arrives; the label approval does not substitute for import entry documentation.

Importers navigating both systems for the first time often find that the Mexican CRM process — which requires on-site inspections, batch sampling, and production verification — takes longer than the TTB COLA review. The fuller picture of how mezcal works as a regulated category in both countries makes clear that the label on a finished bottle represents compliance with a chain of approvals, not just a design choice.
