For Vietnam-made kombucha entering the United States commercially, first determine whether it reaches 0.5% alcohol by volume (ABV) during production, at bottling, or after packaging. That threshold applies even if the release test is lower. The Vietnamese manufacturer documents fermentation and stability. The U.S. importer resolves the import and labeling route. This guide covers U.S. entry, not Vietnam's export procedures.
Determine the applicable alcohol classification
The Alcohol and Tobacco Tax and Trade Bureau (TTB) states that kombucha reaching 0.5% ABV or more at any point, including after bottling, is subject to federal alcohol-beverage regulation. If it remains below that level throughout, the applicable Food and Drug Administration (FDA) food rules govern it. A final-bottle reading alone cannot establish the route. TTB, kombucha regulatory threshold.
Actual product condition | Regulatory consequence | Immediate decision |
|---|---|---|
Below 0.5% ABV throughout production and shelf life | FDA food pathway, without TTB alcohol regulation | Document the evidence and review FDA entry rules |
At or above 0.5% ABV during production or at bottling | TTB alcohol oversight, even if later reduced | Establish the alcohol classification before ordering labels |
Below 0.5% when packed but later reaches 0.5% | TTB alcohol oversight following continued fermentation | Stop a non-alcoholic launch until the product or route is corrected |
Alcohol categories depend on ingredients and process. TTB explains that sugar-fermented kombucha at or above the threshold will generally fall within the Internal Revenue Code (IRC) definition of beer, while Federal Alcohol Administration Act (FAA Act) malt beverage coverage is a separate determination. TTB, classification questions K2 and K6.
Test alcohol during production and across shelf life
Request results during production, at filling and through the claimed shelf life. Include temperature excursions after distribution. TTB specifically warns that refrigeration alone does not reliably prevent subsequent alcohol increases when storage conditions are outside the producer's control. TTB, continued-fermentation questions K3 and K9.
TTB accepts scientifically valid alcohol methods and identifies headspace gas chromatography and validated enzymatic methods among suitable options. Agree on suitable methods near 0.5% ABV and sampling uncertainty. The manufacturer should retain original test records and documented fermentation controls. TTB does not impose its brewery testing requirement on all non-alcoholic producers. TTB, testing questions K17–K19.
Check label, warning and permit requirements by category
Below the threshold, review FDA identity, ingredients, Nutrition Facts and applicable labeling rules. For kombucha within TTB alcohol oversight, an alcoholic-beverage health warning is required when the product contains 0.5% ABV or more. IRC beer labeling and any additional FAA Act requirements depend on classification. FDA, imported-food labeling and TTB, labeling questions K11–K13.
Not every imported kombucha requires a TTB certificate of label approval (COLA). TTB’s formula tool identifies imported kombucha as generally not requiring its formula or label approval. But FAA Act malt beverages, wines and spirits can trigger importer permits and COLAs. If ingredients make that classification uncertain, seek a TTB determination before artwork or entry.

Assign import responsibilities before shipment
The Vietnamese manufacturer supplies the composition, fermentation process, alcohol evidence, shelf-life conditions and proposed label. The U.S. importer and customs broker assess U.S. entry filings. For FDA-regulated food, assess facility registration, Prior Notice and the Foreign Supplier Verification Program (FSVP), including exclusions. FDA notes that the FSVP importer can differ from the customs importer of record. FDA, importer distinction. FDA, importing human foods and FDA, FSVP importer responsibilities.
If the product falls within TTB's alcohol pathway, the U.S. operator must assess alcohol-dealer registration, any FAA Act basic importer permit, federal excise tax, customs duties and state distribution restrictions. FDA Prior Notice can also apply to imported alcohol beverages. The importer should confirm permits with U.S. advisers. TTB, importing bottled alcohol and FDA, Prior Notice.
Resolve the decision before approving a purchase order
- Obtain the complete formula, fermentation steps and ingredient sources from the manufacturer.
- Confirm ABV results throughout processing, at filling and in representative shelf-life conditions.
- Identify the FDA-only or TTB-regulated branch, including any FAA Act classification question.
- Have the U.S. importer validate the actual label, permits, FDA filings and state sales route.
- Hold label approval or shipment release if alcohol stability or classification remains unresolved.

Frequently asked questions
Is a 0.4% ABV bottling certificate enough to market kombucha as non-alcoholic in the U.S.?
No. TTB examines whether the product reaches 0.5% ABV at any point in production or later in the container. A release result must be supported by process and shelf-life evidence. [TTB, kombucha threshold](https://www.ttb.gov/regulated-commodities/beverage-alcohol/kombucha).
Can removing alcohol before bottling take a kombucha outside TTB regulation?
Not automatically. TTB says reaching 0.5% ABV during production triggers alcohol oversight even if the finished beverage later tests below the threshold. The actual manufacturing history matters. [TTB, question K2](https://www.ttb.gov/regulated-commodities/beverage-alcohol/kombucha/kombucha-general).
Does every alcoholic kombucha need the same U.S. label approval?
No. The IRC beer category and the FAA Act malt-beverage category are not identical. TTB’s imported-kombucha formula tool notes no routine TTB formula or label approval, but other classifications can change the permit/COLA path. [TTB, formulation tool](https://www.ttb.gov/regulated-commodities/formulation/which-alcohol-beverages-require-formula-approval-beer-and-malt-beverages-mbev).
Who should decide whether the FDA food-import or TTB alcohol route applies?
The U.S. importer should resolve the route with a broker and, if needed, obtain a TTB classification determination using the manufacturer’s actual ingredients and process. FDA facility and entry duties are separately assessed. [TTB, classification question K6](https://www.ttb.gov/regulated-commodities/beverage-alcohol/kombucha/kombucha-general) and [FDA, import overview](https://www.fda.gov/industry/importing-fda-regulated-products/importing-human-foods).
