When sourcing dietary supplements from a Chinese OEM/ODM manufacturer, getting the label right for the US market is one of the most critical — and most commonly underestimated — compliance challenges. The FDA’s Dietary Supplement Health and Education Act (DSHEA) of 1994 sets the rules, and violations can mean import seizures, warning letters, or worse. This guide walks you through exactly what must appear on your supplement label, what is prohibited, and how to work with your contract manufacturer to avoid costly mistakes.
What DSHEA Means for Your Product Label
DSHEA classifies dietary supplements as a special category: neither conventional food nor drugs. This creates a unique labeling framework. Under DSHEA, a dietary supplement must carry a “Supplement Facts” panel (rather than a “Nutrition Facts” panel used for conventional foods). The label must identify the product, list all ingredients, and include mandatory disclaimer language — all without making unauthorized disease claims.
Mandatory Label Elements
Every supplement label entering the US market must contain the following:
- Identity Statement: The name of the product and its nature as a “Dietary Supplement.”
- Net Quantity: The amount of product in the container (count, weight, or volume).
- Supplement Facts Panel: Required for all supplements. Lists serving size, servings per container, and each dietary ingredient with its amount per serving. For proprietary blends, you must list the total blend weight, but individual ingredients within the blend are listed without their individual amounts.
- Ingredient List: All ingredients in descending order by predominance, including excipients (fillers, binders, coatings, colors, flavors).
- Manufacturer Information: Name and address of the manufacturer, packer, or distributor. A foreign address must include the country of origin.
- DSHEA Disclaimer: The exact statement: “These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.”
What You Cannot Say: Structure/Function vs. Disease Claims
This is where most compliance problems arise. DSHEA permits structure/function claims — statements about how a supplement affects the body’s structure or function — but prohibits disease claims. The line between them is thin and legally consequential.
Examples of permissible structure/function claims:
- “Supports joint health”
- “Promotes healthy energy levels”
- “Maintains bone strength”
Examples of prohibited disease claims (making the product sound like a drug):
- “Treats arthritis” ❌
- “Cures diabetes” ❌
- “Prevents heart disease” ❌
You must also avoid “implicit disease claims” — claims that invoke a disease name even without explicitly stating a treatment. Saying “Supports cardiovascular function” is safer than “Reduces cholesterol,” which regulators may read as a disease-adjacent claim.
Ingredient Declarations: What Your CMO Needs from You
When your contract manufacturer in China prepares your label, they need precise input from you:
- Exact ingredient names as they appear in the FDA’s Food Chemical Codex or the literature — generic names cause mismatches during customs review.
- Specific amounts per serving — including ” proprietary blend” breakdown if applicable.
- Source declarations — certain ingredients like botanical extracts require the plant part (root, leaf, seed) and the extract solvent used.
- Allergen declarations — milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans, and sesame must be declared in plain language on the label.
The New York City Calorie Labeling Rule: Also Apply to Supplements
Don’t assume DSHEA is the only regulation touching your label. If your supplement is sold in retail stores or e-commerce platforms subject to the FDA’s labeling requirements for larger packaging, you may also need to comply with allergen labeling under the Food Allergen Labeling and Consumer Protection Act (FALCPA).
Responsible Third-Party Certification: A Competitive Advantage
Increasingly, US buyers and retailers expect more than legal minimum compliance. Certifications that validate your Chinese manufacturer’s quality and safety systems include:
- FDA Facility Registration: Your manufacturer must be registered with the FDA as a food facility under the Bioterrorism Act.
- cGMP Compliance: Current Good Manufacturing Practice requirements under 21 CFR Part 111 are mandatory for domestic and foreign supplement manufacturers.
- Third-Party Audits: NSF, SQF, or BRCGS certification signals to buyers that your CMO meets internationally recognized food safety standards.
Common Label Rejection Reasons at US Customs
Even products that pass domestic compliance checks get flagged at the border. The most frequent issues include:
- Missing or incorrect Supplement Facts format
- Unauthorized ingredient names or non-FDA-approved novel ingredients
- Missing DSHEA disclaimer or placing it where it’s not legible
- Disease claims in marketing copy included on the label
- Undeclared allergens
