FDA Registration vs GMP Certification for Supplements: What Buyers Get Wrong

Quick answer: they are two different things and neither one is an approval. FDA facility registration is an administrative filing: your factory tells FDA it exists, renews every two years, and accepts unannounced inspection. GMP certification is a third-party audit of how the site manufactures. A supplement factory can hold a perfect GMP certificate and still be unregistered with FDA, and a registered facility can fail a Part 111 inspection. Buyers who treat either one as "FDA approved" are buying a story.

1. What FDA facility registration actually is

Under 21 CFR Part 1 Subpart H, any facility that manufactures, processes, packs or holds food for US consumption — and dietary supplements are food under US law — must register with FDA. The registration records the facility name, address, and the categories of food handled, and it must be renewed in each even-numbered year. A US agent is required for foreign facilities.

What registration triggers: FDA knows the site exists, can inspect it without notice, and can suspend the registration if the facility refuses inspection. What it does not trigger: any review of your formula, your labels, your claims, or your testing. Nobody at FDA reads your product before it ships.

2. What GMP certification actually is

GMP is a standard for how the product is made: premises, equipment, personnel, raw material control, batch records, in-process and finished testing, deviation handling, complaints, recalls. In the US the operative rule for supplements is 21 CFR Part 111. Certification comes from an accredited third party — CQC, Intertek, SGS, TÜV, NSF — or, in China, from the provincial regulator for health food.

The certificate covers a site and a scope. It is evidence about process discipline, and it is the single most useful document you can get from a supplier, precisely because it is auditable: you can look up the number.

3. Side by side

4. The claim to be suspicious of

"FDA approved" does not exist for dietary supplements. FDA has no pre-market approval pathway for them; the regime is post-market. When a supplier sends a document titled "FDA Registration Certificate", what it usually has is a certificate issued by a registration agent — a private company that filed the registration on the factory's behalf and printed a certificate. That is a real administrative step, and it is not an FDA document.

Also expect to see an "FDA registration number" — an 11-digit facility identifier. It is not searchable in a public database. If you need to confirm it, ask the supplier for the FDA confirmation notice issued to the registrant, and cross-check the facility name and address against the production licence.

5. DSHEA, NDI and the piece everyone forgets

Under DSHEA, a dietary ingredient marketed in the US before 15 October 1994 is grandfathered. A new dietary ingredient introduced after that date requires a pre-market notification to FDA at least 75 days before marketing, with safety evidence. A factory cannot do this for you — it belongs to the brand, or to whoever owns the formula.

This is where a "GMP certified, FDA registered" factory can still leave you non-compliant: the ingredient is fine, the plant is audited, and nobody filed the NDI notification. For a first product, budget for this before you approve artwork.

6. What the importer actually needs

For a US-bound shipment of dietary supplements, the working document set is:

• Facility registration confirmation for the manufacturing site, current cycle.
• US agent appointment for the foreign facility.
• Prior notice filed for the shipment (21 CFR Part 1 Subpart I).
• FSVP records if your buyer is the foreign supplier's importer — hazard analysis, supplier verification, corrective actions (21 CFR Part 1 Subpart L).
• CoA per batch, with the test panel and the specification it was released against.
• Label artwork checked against 21 CFR 101.36 (Supplement Facts) and the DSHEA claim rules.
• For new ingredients: the NDI notification and FDA's response.

Missing any of those is a hold at the port or a letter later, regardless of how good the GMP certificate looks.

7. How to verify both claims in one afternoon

1. Certificate number → issuer portal. Check scope, address, expiry.
2. Production licence → permitted dosage forms. Compare with the certificate scope.
3. Registration confirmation → facility name and address must match the licence, not a sister plant.
4. FDA inspection database → search the facility name for classifications and warning letters.
5. Prior notice → ask who files it and get a sample confirmation from a recent shipment.
6. Label → read the Supplement Facts panel against your formula; check the %DV column and the disclaimer.

8. Why the two get confused in sales decks

Both are cheap to state and expensive to disprove, and both sound like approval to a buyer who has not dealt with FDA before. The tell is a supplier who leads with "FDA registered" and goes quiet when you ask for the certificate number behind the GMP claim. Registration is a filing; GMP is an audit; neither is a permission slip for your label.

9. The label checklist that decides whether the shipment clears

Registration and GMP get the factory through the door; the label is what gets your product into the country. For the US, the Supplement Facts panel is prescribed in detail, and getting it wrong is the most common reason a first shipment is refused or a listing is pulled.

Two practical notes. First, the %DV column depends on the form and the age group, and it must match the dose actually in the batch — a label written for 2 capsules and a formula dosed at 3 is a defect. Second, a structure/function claim without the disclaimer is treated as a misbranded product even if everything else is correct.

10. What FDA does after the shipment arrives

There is no approval step, so the exposure is post-market: import alerts, detention without physical examination, inspections and warning letters, and in the worst case a recall you fund. Three mechanisms are worth knowing before you plan a launch date:

• Import alert. A firm or country can be placed on an alert that detains shipments automatically until the firm demonstrates compliance. It is published and searchable.
• Inspection. Foreign facilities are inspected; findings are classified and published. A pattern of findings across a supplier's customers can trigger follow-up.
• Adverse event reporting. Serious adverse events must be reported to FDA, and the record-keeping obligation sits with the brand, not the factory.

This is why the compliance file — registration confirmation, prior notice, CoA, label review, NDI where applicable — should be assembled before the first production run rather than after the first shipment is held.

Frequently asked questions

Is FDA registration mandatory for a Chinese supplement factory?

Yes, if the facility manufactures, processes, packs or holds dietary supplements for US consumption. Foreign facilities must also designate a US agent. Renewal is required in each even-numbered year, and the registration can be suspended if the facility refuses an FDA inspection.

Does FDA inspect Chinese supplement factories?

Yes. FDA conducts foreign inspections, including of dietary supplement facilities, and publishes inspection classifications and warning letters. Search the facility name in FDA's inspection database before committing to a supplier; a recent voluntary action or warning letter is material information.

Can a factory be GMP certified but not FDA registered?

Absolutely, and it is common. GMP certification is a commercial audit against a standard, often ISO 22000 or China health food GMP; FDA registration is a separate US-specific obligation triggered only by selling into the US.

Is a certificate from a registration agent worth anything?

It confirms that the agent filed the registration. It is not an FDA document and does not certify manufacturing practice. Use it as one data point, then verify the facility name, address and registration cycle yourself.

Do I need FDA approval before selling a supplement in the US?

No. There is no pre-market approval for dietary supplements. The obligations are on the brand: compliant labelling, substantiated claims, NDI notification where applicable, and manufacturing at a registered facility operating under 21 CFR Part 111.

Which document should I ask for first?

The GMP certificate, because it is independently verifiable. Then the facility registration confirmation, because it is not. Starting with the verifiable one filters out suppliers who are improvising.
