How to Export Supplements to the USA

• Contents

To successfully export dietary supplements to the US, your company must comply with regulations set by the Food and Drug Administration (FDA)—which classifies these products as dietary supplements—and fulfill the requirements of the Foreign Supplier Verification Program (FSVP), which shifts the legal responsibility of auditing and validating your manufacturing processes and safety standards to the US importer.

However, strict regulatory enforcement leaves no room for improvisation. Errors in formulations, labeling mistakes, or a lack of preventive documentation can lead to shipments being detained at ports of entry by U.S. Customs and Border Protection (CBP), resulting in demurrage/storage fees, cargo destruction, or mandatory re-exportation of the lot.

Regulatory Framework for Dietary Supplements in the United States

Unlike prescription drugs, dietary supplements do not undergo FDA pre-market approval before hitting retail shelves. The entire legal foundation rests upon the Dietary Supplement Health and Education Act of 1994 (DSHEA). Under this statute, supplements fall into a specialized category within foods, placing the primary responsibility for safety, purity, and truthful labeling directly on the manufacturer and distributor.

Although individual batches are not cleared prior to distribution, post-market surveillance is rigorous. The FDA conducts periodic facility audits, reviews mandatory serious adverse event reports, and tests border samples. If a formula contains unapproved substances, biological or chemical contaminants, or makes unauthorized disease claims, the agency issues Warning Letters, mandates public recalls, and places facilities on Import Alerts, cutting off future shipments.

FDA Requirements for Foreign Manufacturers

Foreign supplement manufacturing facilities shipping goods to US territory must satisfy four pillars:

Food Facility Registration: 

Any facility that manufactures, processes, packs, or holds dietary supplements for US consumption must register with the FDA under Section 415 of the Federal Food, Drug, and Cosmetic Act. Registrations must be renewed every two years (in even-numbered years between October and December). Foreign entities must also appoint a designated U.S. Agent—a resident individual or domestic business entity acting as the official communications liaison with the FDA.

cGMP Compliance (21 CFR Part 111): 

Current Good Manufacturing Practices governing dietary supplements are detailed under 21 CFR Part 111. Key requirements include:

• Comprehensive qualification and quality control of raw material suppliers.
• Written specifications for identity, purity, strength, and composition, alongside strict limits on contaminants (heavy metals, pesticides, microbial pathogens).
• Batch-specific Certificates of Analysis (CoAs) supported by validated analytical methods.
• Standard Operating Procedures (SOPs) covering equipment calibration, sanitation, and full end-to-end traceability.

New Dietary Ingredient (NDI) Notification: 

If your formulation incorporates an herb, botanical, mineral, or other dietary substance not marketed in the US prior to October 15, 1994, it is categorized as a New Dietary Ingredient (NDI). Manufacturers must submit an NDI safety notification to the FDA at least 75 days before introducing the product into interstate commerce, backed by toxicological and safety evidence supporting its intended dosage.

Supplement Facts Compliant Labeling: 

Labeling deficiencies represent one of the most common grounds for customs refusals. Packaging must feature a compliant Supplement Facts panel, a descending list of ingredients, mandatory major food allergen disclosures (pursuant to FALCPA and related updates), net contents displayed in both US customary (ounces/pounds) and metric units, plus the distributor’s business name and address. Structure/function claims are permitted only when accompanied by the standard statutory disclaimer clarifying that the product is not intended to diagnose, treat, cure, or prevent any disease.

The Role of the FSVP in Your Importer Relationship

Established under the Food Safety Modernization Act (FSMA), the Foreign Supplier Verification Program (21 CFR Part 1, Subpart L) changed trade with the United States. Rather than relying on border checks, the federal government placed technical verification responsibilities on the US-based FSVP Importer.

The US importer bears legal liability before the FDA for the safety of imported items. Consequently, before signing distribution agreements or issuing purchase orders, they will request a complete technical file from your plant.

In practice, failure to provide the records needed for an importer’s FSVP file will halt commercial transactions, regardless of consumer demand.

Prior Notice

Once the product is manufactured, correctly labeled, and documented under the FSVP, customs clearance and transit can proceed. Every international shipment of food and supplements bound for the US requires advance electronic filing of a Prior Notice of Imported Foods via FDA portals.

Prior Notice submissions must adhere to mandatory timeframes before arrival at a US port of entry: 2 to 8 hours prior for truck, rail, or air cargo, and up to 24 hours before vessel arrival for ocean freight. The generated Prior Notice Confirmation Number must accompany shipping documents (such as the Bill of Lading or Air Waybill) to permit automated data matching by CBP and the FDA during customs review.

Frequently Asked Questions (FAQ)

How do I verify if my formula's ingredients are permitted in the USA?
Check the regulatory status of each component against the FDA’s Generally Recognized as Safe (GRAS) databases, historical pre-1994 dietary ingredient compendia, or assess whether an NDI notification is warranted. Unapproved food additives, adulterants, or compounds possessing pharmaceutical activity cannot legally be sold as dietary supplements and will trigger shipment detention.

Does the US importer have to be a physical US company?
Yes. Under FSVP mandates, the responsible importer must be an entity legally registered in the United States with a domestic physical address and an Employer Identification Number (EIN), or a formally designated FSVP Agent if no foreign buyer maintains a domestic presence. This designated entity assumes legal accountability for safety verifications under FDA oversight.
