FDA Registration for Bottled Water
This guide covers FDA registration for bottled water, the six FDA standards of identity under 21 CFR Part 165, the 250 ppm TDS requirement for mineral water, EU vs. FDA mineral water mismatches, municipal source disclosure, fluoride labeling, and what bottled water importers most commonly get wrong.
The Six FDA Bottled Water Identity Types — Use the Wrong One and It’s Misbranding
| Label Term | 21 CFR Citation | Definition and Requirements | Common Import Violation |
|---|---|---|---|
| Spring Water | 165.110(a)(2)(vi) | Water from an underground formation that flows naturally to the surface. Collected at the spring or through a borehole tapping the same underground stratum. If pumped, must exhibit the same composition and quality as the naturally flowing water. | Labeling treated municipal water as “spring water.” Labeling water from a borehole that does not tap the same stratum as the natural spring. |
| Purified Water | 165.110(a)(2)(iv) | Water produced by distillation, deionization, reverse osmosis, or other processes meeting USP Purified Water standards. May add method variant: “distilled,” “deionized,” “reverse osmosis.” | Missing municipal source disclosure when the source is a public water supply (unless meets purified water standards). Claiming “purified” without meeting USP specifications. |
| Mineral Water | 165.110(a)(2)(iii) | Water from a protected underground source with ≥ 250 ppm TDS. Constant mineral composition at the point of emergence. No added minerals permitted. | TDS below 250 ppm (very common for European “natural mineral water” imports). Adding minerals to water not from a protected natural source. |
| Sparkling Water | 165.110(a)(2)(v) | Water containing the same amount of CO₂ after treatment as at emergence from the source. Added CO₂ to replace naturally occurring CO₂ is permitted. | Carbonating non-sparkling spring or mineral water and labeling as “sparkling spring water” when the amount of CO₂ exceeds the natural level. |
| Artesian Water | 165.110(a)(2)(i) | Water from a well tapping a confined aquifer where the water level stands above the top of the aquifer. | Using “artesian” for water from an unconfined aquifer or a non-artesian well. |
| Well Water | 165.110(a)(2)(vii) | Water from a hole bored, drilled, or otherwise constructed into the ground which taps an aquifer. | Infrequently misused — the least prestige-associated term. |
The 250 ppm TDS Threshold and the EU “Natural Mineral Water” Mismatch
What European Mineral Water Importers Must Do
Before importing a European bottled water labeled “natural mineral water”: (1) Test the water for TDS. (2) If TDS ≥ 250 ppm AND the water comes from a protected underground source with constant mineral composition: “mineral water” label may be used in the U.S. (subject to “no added minerals” requirement). (3) If TDS < 250 ppm: cannot use “mineral water.” Use “spring water” (if the source qualifies) or another appropriate FDA-defined term. (4) Prepare a new U.S.-compliant label using the correct FDA-defined identity term.
No Added Minerals Rule — Additional Mineral Water Requirement
FDA’s mineral water standard requires that no minerals be added to the water. A product that takes water from a natural source and adds minerals to increase TDS above 250 ppm cannot be labeled “mineral water” — it could be labeled “mineral-enhanced water” or “purified water with added minerals” depending on the source and processing. This catches some imported products that have been mineral-fortified.
When Bottled Water Must Disclose a Municipal Source
Nutrition Facts Panel — Required Even for Plain Water
All bottled water sold in the United States requires a Nutrition Facts panel under 21 CFR Part 101.9 — even plain water showing 0 for all nutrients. The RACC serving size is 240 mL (8 fl oz) under 21 CFR Part 101.12. The 2020 FDA format is required. Many imported bottled water products lack a Nutrition Facts panel or use pre-2020 formats.
Net Quantity — Both FL OZ and mL Required
The net quantity on the Principal Display Panel must be declared in both fluid ounces (or gallons) AND milliliters (or liters). “500 mL” alone is non-compliant — must read “16.9 FL OZ (500 mL)”. “1 L” alone is non-compliant — must read “33.8 FL OZ (1 L)”. Net quantity must appear in the lower 30% of the PDP.
Fluoride Labeling Requirements
Under 21 CFR 165.110(c), bottled water with added fluoride must declare the fluoride content on the label. Naturally occurring fluoride is not “added” fluoride. If fluoride is added to bottled water marketed for infants or young children, specific statements about appropriate use may be required. FDA has set maximum fluoride levels for bottled water by climate zone.
How to Register a Bottled Water Manufacturing Facility with FDA
Standards of Identity Review
FDA Registration Assistance reviews the bottled water product’s claimed identity type against the FDA definition. For mineral water imports: TDS verification against the 250 ppm threshold. For spring water: source documentation review. For purified water: processing method and USP specification compliance. For European imports: EU vs. FDA standard mismatch assessment with recommended U.S. label term.
Label Review Included
FDA Registration Assistance reviews bottled water labels for: standards of identity accuracy; 240 mL RACC serving size; net quantity in both FL OZ and mL; Nutrition Facts in 2020 FDA format (even for 0-calorie plain water); municipal source disclosure if applicable; fluoride content labeling; and English language requirements. Identifies compliance gaps before the first shipment.
U.S. Agent and Registration
Foreign bottled water manufacturers must designate a U.S. Agent with a physical U.S. address. FDA Food Facility Registration submitted through FURLS. FDA registration number provided for use in Prior Notice filings for every water shipment.
FSVP for Bottled Water Importers
U.S. importers must maintain FSVP for each foreign bottled water supplier. Hazard analysis must address microbiological hazards (coliform, E. coli), chemical hazards (arsenic, lead, nitrates), standards of identity compliance, and physical hazards. Periodic product testing for FDA quality standard compliance.

Frequently Asked Questions — FDA Registration for Bottled Water
1. Do bottled water manufacturers need FDA registration?
Yes. Bottled water is regulated as a food under the FD&C Act. All facilities must register under 21 U.S.C. § 350d and 21 CFR Part 1 Subpart H. Foreign manufacturers must also designate a U.S. Agent. Complete service: $858. FDA charges $0. DUNS fees separate.
2. What are the FDA standards of identity for bottled water?
Under 21 CFR Part 165.110: Spring water — from underground formation flowing naturally to surface; Purified water — distillation, deionization, or RO meeting USP standards; Mineral water — ≥ 250 ppm TDS, protected underground source, no added minerals; Sparkling water — CO₂ equal to source level; Artesian water — confined aquifer; Well water — from drilled aquifer. Using the wrong term is misbranding under 21 U.S.C. § 343.
3. What is FDA’s definition of spring water?
Under 21 CFR 165.110(a)(2)(vi): water from an underground formation that flows naturally to the surface, collected at the spring or through a borehole tapping the same underground stratum. If pumped, must exhibit the same composition as the naturally flowing water. Municipal tap water that has been treated cannot be labeled “spring water.”
4. What is FDA’s definition of mineral water and the 250 ppm TDS requirement?
Under 21 CFR 165.110(a)(2)(iii): water from a protected underground source with ≥ 250 ppm TDS; constant mineral composition at emergence; no added minerals. Water with TDS below 250 ppm cannot be labeled “mineral water” in the United States regardless of its natural source.
5. What is FDA’s definition of purified water?
Under 21 CFR 165.110(a)(2)(iv): water produced by distillation, deionization, reverse osmosis, or other processes meeting USP Purified Water standards. May also be labeled “distilled water,” “deionized water,” or “reverse osmosis water” based on the specific process. Municipal source must be disclosed unless the water meets purified water standards.
6. Does EU “natural mineral water” classification satisfy FDA’s mineral water standard?
Not necessarily. EU natural mineral water (Directive 2009/54/EC) has no minimum TDS requirement. FDA requires ≥ 250 ppm TDS. Many popular European mineral waters have TDS well below 250 ppm and cannot be labeled “mineral water” in the United States. Must use “spring water” or another appropriate FDA-defined term based on actual characteristics.
7. What labeling is required on bottled water for the U.S. market?
Under 21 CFR Part 101 and 21 CFR Part 165.110: correct FDA-defined identity term; net quantity in both FL OZ and mL in the lower 30% of the PDP; Nutrition Facts panel in 2020 FDA format (even for plain water); manufacturer/distributor name and U.S. address; municipal source disclosure if applicable. All required text in English.
8. Does plain bottled water need a Nutrition Facts panel?
Yes. All bottled water requires a Nutrition Facts panel under 21 CFR Part 101.9. Plain water shows 0 for all nutrient values. The RACC is 240 mL (8 fl oz) under 21 CFR Part 101.12. The 2020 FDA format is required. Missing Nutrition Facts panel = misbranding.
9. What is the FDA serving size (RACC) for bottled water?
240 mL (8 fl oz) under 21 CFR Part 101.12. Net quantity must be in both FL OZ and mL: “16.9 FL OZ (500 mL)” or “33.8 FL OZ (1 L).” Metric-only declaration (500 mL without FL OZ) is non-compliant.
10. What are the labeling requirements if bottled water comes from a municipal supply?
Under 21 CFR 165.110(a)(3), bottled water from a community water system must disclose the source with language such as “from a community water system” or “from a public water system” — unless it has been further treated to meet purified water standards. Prevents consumers from being misled about whether the water comes from a natural source vs. treated tap water.
11. What FDA quality standards apply to bottled water?
Under 21 CFR 165.110(b), FDA has set MCLs (maximum contaminant levels) for bottled water paralleling EPA’s standards for public drinking water. These cover microbiological, chemical, physical, and radiological contaminants. FDA actively samples imported bottled water for contaminant compliance. Bottled water exceeding FDA MCLs is subject to recall.
12. What are the FDA labeling requirements for fluoride in bottled water?
Under 21 CFR 165.110(c), bottled water with added fluoride must declare the fluoride content. FDA has set maximum fluoride levels by climate zone. Naturally occurring fluoride is not “added.” Bottled water marketed for infants with added fluoride requires specific statements about appropriate use.
13. What are the FDA regulations for sparkling water?
Under 21 CFR 165.110(a)(2)(v): water containing the same CO₂ at point of use as at emergence from the source. Added CO₂ to replace naturally occurring CO₂ is permitted. “Seltzer water,” “club soda,” and “tonic water” are not covered by FDA’s bottled water standard — they are soft drinks with different labeling requirements.
14. What is the difference between bottled water and flavored water for FDA?
Plain bottled water falls under FDA’s bottled water standards (21 CFR Part 165). Flavored water with added fruit flavors, sweeteners, or other ingredients is regulated as a beverage under 21 CFR Part 101. Enhanced water with vitamins, minerals, or herbal extracts at supplement levels may be classified as a dietary supplement requiring a Supplement Facts panel.
15. Do foreign bottled water manufacturers need a U.S. Agent?
Yes. Foreign manufacturers must register and designate a U.S. Agent with a physical U.S. address. FDA Registration Assistance provides U.S. Agent services for foreign bottled water manufacturers.
16. What FSVP requirements apply to U.S. bottled water importers?
U.S. bottled water importers must maintain FSVP under 21 CFR Part 1 Subpart L for each foreign supplier. Hazard analysis must address: microbiological hazards (coliform, E. coli, Pseudomonas); chemical hazards (arsenic, lead, nitrates); standards of identity compliance; and physical hazards. Periodic product testing for FDA quality standard compliance.
17. What is the $858 complete service?
FDA Registration Assistance charges $858 — U.S. Agent designation for foreign manufacturers, activity code selection, food product category selection, registration submission through FURLS, and Biennial Renewal management. FDA charges $0. DUNS fees are separate.
18. Why do bottled water shipments get detained at U.S. ports?
Most common causes: facility registration expired or not filed; standards of identity violation (“mineral water” with TDS below 250 ppm; “spring water” not from a qualifying source); missing Nutrition Facts panel or non-compliant 2020 format; net quantity in metric only without FL OZ; no municipal source disclosure; contaminant levels exceeding FDA quality standards; Prior Notice errors.
19. What activity codes should a bottled water manufacturer select?
Manufacture (treating, purifying, carbonating, or processing water and filling into bottles); Pack (filling, sealing, and packaging); Hold (if the facility warehouses finished bottled water). Under 21 CFR 1.234, update within 60 days when new product types are added.
20. What is the Biennial Renewal for bottled water registrations?
FDA Food Facility Registration renews every two years — October 1 through December 31 of even-numbered years. A lapsed registration triggers OASIS detention of every subsequent shipment. FDA Registration Assistance manages Biennial Renewal automatically.
21. Does FDA or EPA regulate bottled water?
FDA regulates bottled water as a packaged food under the FD&C Act (21 CFR Part 165). EPA regulates public tap water under the Safe Drinking Water Act. FDA’s bottled water quality standards are required to be at least as stringent as EPA’s MCLs for comparable contaminants.
22. Can bottled water be labeled “natural” under FDA regulations?
FDA has not established a regulatory definition for “natural” as a food claim. “Natural” is not a defined term under FDA’s bottled water standards (21 CFR Part 165). However, a “natural” claim on bottled water derived from a treated municipal supply could be considered misleading under 21 U.S.C. § 343(a).
23. What labeling requirements apply to European mineral water imports?
Must comply with FDA’s standard of identity under 21 CFR 165.110(a)(2)(iii) — not EU Directive 2009/54/EC. Key check: TDS ≥ 250 ppm required for the “mineral water” label. Many popular European mineral waters have TDS below 250 ppm and must use “spring water” or another FDA-defined term on U.S. labels.
24. How does FDA Registration Assistance help bottled water manufacturers and importers?
Complete FDA compliance: Food Facility Registration with correct activity codes; U.S. Agent for foreign manufacturers; standards of identity review (TDS verification, EU vs. FDA mismatch); label compliance review (240 mL RACC, FL OZ + mL net quantity, Nutrition Facts, municipal source disclosure); FSVP programs; Biennial Renewal. $858 service. FDA charges $0. 1,000+ clients. 135+ countries.
