Export US Dietary Supplement Labeling Compliance: A Complete Guide for International Manufacturers

What Every OEM Partner Must Know Before Shipping to the American Market

For international nutraceutical manufacturers, entering the U.S. market is one of the most rewarding yet challenging opportunities in the global supplement industry. With over 77% of American adults taking some form of dietary supplement, the demand is massive. However, the regulatory landscape—anchored by the FDA’s Dietary Supplement Health and Education Act (DSHEA) of 1994—is notoriously strict. Non-compliant labeling is one of the top reasons shipments are detained, recalled, or refused entry at U.S. ports.

This guide breaks down the mandatory labeling elements, common pitfalls, and practical steps your OEM/ODM partner must take to ensure full compliance.

1. Why DSHEA Matters for Your Label

DSHEA classifies dietary supplements as a special category: they are neither drugs nor conventional foods. This means your product can reach market without pre-market approval—but your label must carry specific mandatory disclosures. The FDA enforces these requirements under 21 CFR Part 101.

Failure to comply can result in import detentions under FDA’s Import Alert system, civil penalties, or mandatory recalls. For a contract manufacturer, this is a reputational and financial risk you cannot afford.

2. Mandatory Label Elements (21 CFR Part 101)

Every dietary supplement label sold in the United States must display the following:

A. Identity Statement

The product name must accurately describe the product type. “Dietary Supplement” must appear on the principal display panel (PDP), along with the net content.

B. Manufacturer Information

Either the name and place of business of the manufacturer, packer, or distributor must be listed. A foreign manufacturer must provide a U.S. agent or importer’s address if the foreign entity does not have a U.S. presence.

C. Supplement Facts Panel

Replacing the traditional Nutrition Facts panel used for foods, dietary supplements must display a Supplement Facts panel. This includes:

• Serving size and servings per container
• Active ingredients (with amounts per serving)
• Other ingredients (in descending order of predominance)
• Allergens (milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans, sesame)

D. Ingredient List

All ingredients must be listed by their common or usual name. For proprietary blends, individual ingredients must be listed but individual amounts may be hidden behind the blend total.

E. Allergen Declarations

The “Big 9” allergens must be clearly declared: milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, soybeans, and sesame (as of January 1, 2023 under the FASTER Act).

F. California Proposition 65 Warnings

If your product contains chemicals listed under Prop 65 (including certain vitamins, minerals, or contaminants), a clear and reasonable warning must appear. Many international manufacturers overlook this—particularly for products containing lead, cadmium, or acrylamide.

G. Health Claims & Nutrient Content Claims

This is the area where most compliance issues arise:

Authorized Health Claims (Significant Scientific Agreement / SSA standard): Must be substantiated by published, credible scientific evidence. Example: “Calcium may reduce the risk of osteoporosis.”

Qualified Health Claims: When evidence is less definitive, the FDA allows qualified claims with a disclaimer. Example: “Supportive but not conclusive research shows…”

Structure/Function Claims: These claims describe an effect on the structure or function of the body (e.g., “Supports joint health”) but cannot claim to diagnose, treat, cure, or prevent any disease. If you use structure/function claims, you must include a disclaimer: “This statement has not been evaluated by the FDA. This product is not intended to diagnose, treat, cure, or prevent any disease.”

Prohibited Claims: Claims that suggest the product is a drug or that it can treat a disease are strictly prohibited and can result in product reclassification as an unapproved drug.

H. Net Quantity Statement

Must state the net contents in both U.S. customary and metric units.

3. Common Compliance Pitfalls for International OEM Partners

Pitfall 1: “Made in USA” Claims

If your supplement is manufactured abroad, you cannot label it as “Made in the USA” unless it meets the FTC’s “all or virtually all” standard. Misleading origin claims are a common cause of regulatory action.

Pitfall 2: Unapproved New Dietary Ingredients (NDIs)

If your formulation includes an ingredient introduced after October 15, 1994, you must file an NDI notification with the FDA before marketing the product. Many overseas manufacturers use ingredients that have not completed this process, creating significant compliance risk for U.S. importers.

Pitfall 3: Insufficient cGMP Compliance Documentation

FDA requires that dietary supplement manufacturers follow Current Good Manufacturing Practices (cGMPs) per 21 CFR Part 111. International manufacturers must maintain batch records, testing logs, and supplier verification records. U.S. importers increasingly request these documents during due diligence.

Pitfall 4: Third-Party Lab Testing Not Disclosed

Claims like “第三方检测” or “Independently Tested” without documentation supporting the claim can be considered misleading. If you promote third-party testing, ensure the lab is FDA-registered and results are on file.

4. How Your OEM Partner Should Prepare

For international brands sourcing from contract manufacturers like Dongying Zuoning Bio, the OEM partner should:

1. Conduct a label review against 21 CFR Part 101 before production runs
2. Verify NDI status for every active ingredient in the formulation
3. Maintain allergen cross-contamination protocols and document them
4. Provide batch-specific Certificates of Analysis (CoA) with each shipment
5. Keep DSHEA-compliant disclaimer language in all marketing materials shared with U.S. customers
