FDA DSHEA Compliance: Key Labeling Requirements for U.S. Dietary Supplement Exports

If you are sourcing dietary supplements from a Chinese contract manufacturer for the U.S. market, getting the label right is not optional — it is the difference between smooth customs clearance and a shipment seizure. Under the Dietary Supplement Health and Education Act of 1994 (DSHEA), the U.S. Food and Drug Administration (FDA) enforces specific labeling rules that every overseas manufacturer and their buyers must understand before production begins.

This guide walks you through the essential labeling requirements under DSHEA, common compliance pitfalls, and practical steps your OEM partner should take to ensure your product is market-ready.

1. What DSHEA Means for Your Product

DSHEA defines “dietary supplements” to include vitamins, minerals, herbs, amino acids, and other ingredients intended to supplement the diet. If your product falls into this category, the FDA treats it as a dietary supplement — not a food or drug — and regulates it accordingly.

The critical implication: dietary supplements do not require pre-market FDA approval. However, manufacturers and importers are responsible for ensuring their products are safe and properly labeled. The FDA can take action against products that are adulterated, misbranded, or make unauthorized health claims.

2. The Supplement Facts Panel

Since 1994, all dietary supplements sold in the U.S. must display a Supplement Facts panel, not a Nutrition Facts panel (which is required for conventional foods). This panel must include:

• Serving size and servings per container — based on the recommended intake
• Active ingredients — each dietary ingredient listed by name and amount per serving
• Other ingredients — excipients, fillers, binders, flavors, and colors listed below the active ingredients
• % Daily Value (DV) — based on the Daily Value reference values established by the FDA

The Supplement Facts format is strictly regulated. Your OEM manufacturer must use the exact FDA-specified format, font size, and order of information. A common mistake is using a food-style Nutrition Facts panel — this is a misbranding violation.

3. The Ingredient List and Identity Disclosure

All ingredients must be listed by their common or usual name, in descending order by predominance. For proprietary blends, each ingredient must be listed, but the total blend amount is disclosed rather than individual ingredient amounts.

Key rules:

• Dietary ingredients (vitamins, minerals, herbs, etc.) must be listed in the Supplement Facts panel
• Non-dietary ingredients (excipients) must be listed in the “Other Ingredients” section
• Color additives must be listed by name (e.g., “Titanium Dioxide”) or by FDA designated names (e.g., “FD&C Yellow No. 5”)

4. Ingredient Safety: The “New Dietary Ingredient” (NDI) Rule

If your formulation includes any ingredient that was not marketed in the U.S. before October 15, 1994, it is classified as a New Dietary Ingredient (NDI). Under DSHEA, NDI-containing products require an NDI Notification (NDIN) submitted to the FDA at least 75 days before commercial marketing.

This is one of the most commonly overlooked requirements in international OEM partnerships. Chinese manufacturers sometimes use botanical extracts or fermented ingredients that are considered NDIs in the U.S. Without proper NDIN documentation, your product is technically adulterated and subject to FDA enforcement action.

What you should do:

• Request a full ingredient audit from your manufacturer before production
• Confirm that all ingredients either have a history of use in the U.S. or have an approved NDIN
• If in doubt, consult a U.S. regulatory affairs specialist

5. Forbidden and Restricted Claims

Health claims describe a relationship between a product and a risk of disease. They fall into three categories:

1. Authorized Health Claims — Supported by significant scientific agreement (SSA), e.g., “Adequate calcium and vitamin D may reduce the risk of osteoporosis.” These require specific wording and qualifiers.
2. Qualified Health Claims (QHCs) — Supported by emerging but not yet conclusive evidence. These require qualifying language such as “scientific evidence suggests… but the evidence is not conclusive.”
3. Structure/Function Claims — Describe an effect on the structure or function of the body (e.g., “Supports joint health”). These do not require FDA pre-approval, but the manufacturer must have substantiation and include an FDA disclaimer: “This statement has not been evaluated by the FDA. This product is not intended to diagnose, treat, cure, or prevent any disease.”

What you must avoid:

• Disease claims — stating that a product treats, diagnoses, or prevents a disease (e.g., “cures diabetes” or “treats heart disease”) is illegal without an FDA-approved drug claim
• Unsubstantiated claims — any claim without adequate scientific support
• Implied claims through testimonials or product names

The FDA has issued warning letters specifically to companies using aggressive marketing language. As a buyer sourcing OEM products, ensure your label and your marketing materials align — discrepancies between the two are a red flag during FDA inspections.

6. Manufacturer Information and Batch Traceability

DSHEA requires that the label identify the manufacturer or distributor by name and address. If the product is manufactured by a third-party OEM (as is the case in most international partnerships), you have two options:

• List the contract manufacturer’s name and address, or
• Use a distributor/importer statement such as “Distributed by [Company Name], [City, State]”

Your OEM manufacturer should provide:

• Batch records with lot numbers for full traceability
• Certificate of Analysis (CoA) for each production batch
• GMP (Good Manufacturing Practice) compliance documentation, per 21 CFR Part 111

7. Allergen Declaration

Since 2006, the Food Allergen Labeling and Consumer Protection Act (FALCPA) requires dietary supplement labels to declare the presence of any of the eight major food allergens:

• Milk, Eggs, Fish, Shellfish
• Tree Nuts, Peanuts, Wheat, Soybeans
• Sesame (effective January 1, 2023)

Allergens must be declared either in the ingredient list (in parentheses after the ingredient name) or in a “Contains” statement.

8. Practical Checklist for Your OEM Partner

Before signing a manufacturing agreement, confirm your OEM partner can deliver:

• [ ] Supplement Facts panel designed to FDA format specifications
• [ ] Full ingredient safety review, including NDI status verification
• [ ] Appropriate health/structure-function claim language with required disclaimers
• [ ] Allergen declaration in compliant format
• [ ] Manufacturer/distributor identity on label
• [ ] Batch-level traceability documentation (CoA, batch records)
• [ ] cGMP-compliant production (21 CFR Part 111)
• [ ] Claims review for marketing materials (label + website + social media)

Conclusion

FDA DSHEA compliance is not a one-time checklist — it is an ongoing responsibility that starts at product conception and continues with every new batch. As a buyer, your best protection is partnering with a manufacturer who understands U.S. regulatory requirements from the ground up, not just one who can fill capsules.
