TL;DR
Short answer: Supplements are a documentation-first category: build the compliance file before you list, not after a platform asks for it. Three layers are required — facility documents (GMP certificate and FDA registration), lot documents (a finished COA for every batch), and label documents (Supplement Facts panel plus claim substantiation). Match the lot numbers on each COA to the lot codes printed on your bottles, and ask for the whole proof bundle before you place the order.
Amazon has made dietary supplements a documentation-first category: when a listing is gated, flagged or challenged, sellers must produce facility evidence and lot-level test results — often within days. Brands that assembled the file on day one answer in hours. Brands that didn’t scramble, get suspended, or quietly lose their buy box while “documents are being collected.”
The good news: the document bundle is knowable and finite. This checklist covers all three layers — what to verify before you order, what to collect at production and shipment, and what to keep ready before you list.
Third-party GMP certificate (current)
Accredited auditor, facility address, issue and expiry dates, and audit scope covering your dosage form. A capsule audit does not certify gummies. (Related: our FDA vs cGMP guide.)
FDA facility registration confirmation (FEI)
Registration confirmation tied to the address that will run your batch. Registration is not approval — it is the baseline that makes inspection possible.
Redacted finished-product COA, recent lot, your dosage form
Methods, specification ranges, actual results and a named ISO 17025 lab. Learn the eight checks in our COA guide before you review it.
Subcontractor disclosure
If gummy depositing, encapsulation or testing is outsourced, the subcontractor needs its own GMP status. Get the disclosure in writing.
| Check | Why it matters | Who delivers it |
|---|---|---|
| Lot-specific finished COA per batch | Proves your batch met spec before release; micro and metals tested. | Manufacturer QC / ISO 17025 lab |
| Lot codes printed on bottles match COA | Traces every unit you sell back to its test report. | Manufacturer |
| Supplement Facts panel & allergen statements | FDA-format labeling; correct “Contains” and allergen declarations. | Compliance design review |
| FNSKU tags attached, case labels correct | Stock is shelf-ready at the fulfillment center — no repackaging delays. | Fulfillment / freight desk |
| Expiry & stability rationale | Supports your shelf-life claim if asked. | Manufacturer QA |
Structure-function language only
“Supports”, “maintains”, “promotes” — fine. “Treats”, “cures”, “prevents disease” — never. Review listing copy with the same discipline as the label.
One compliance file per batch, kept for the product’s life
COA, lot code range, shipment docs and label proof in one place. When a document request arrives, you answer in hours, not weeks.
Every private label order ships with its lot-specific ISO 17025 COA, FDA-format Supplement Facts proofing is part of the free label design workflow, FNSKU barcode tags are attached before dispatch, and freight handles customs clearance direct to US/EU FBA. The framework behind it is published on our Quality & Compliance page, and you can inspect the COA format by downloading a sample before you ask anything.
What documents does Amazon ask supplement sellers for?
When a listing is gated or challenged, brands are typically asked for facility evidence (GMP certification from an accredited auditor, FDA registration confirmation) and lot-level finished-product COAs. Compile the bundle proactively before listing.
Do I need a COA for every lot I sell on Amazon?
Yes, in practice. Keep a lot-level COA per batch and confirm the lot number matches the code on the bottles. See our COA guide for how to check one properly.
What is an FEI number and why does it matter?
The FEI is the FDA’s Establishment Identifier for a registered facility. Registration confirmation tied to the facility address documents that production happened at a registered site.
Can my manufacturer attach FNSKU barcodes and ship directly to FBA?
Yes. NutraForge attaches FNSKU tags and ships direct to US/EU Amazon FBA with customs clearance handled by our freight desk.
How do health claims affect a supplement listing?
Use structure-function language only; never claim to diagnose, treat, cure or prevent disease. Have labels and listing copy reviewed before launch.
How early should I start compliance paperwork?
Before you order. Request the facility proof bundle while evaluating manufacturers, then collect lot-specific COAs with every shipment.
Send a quick RFQ — within 12 hours you’ll receive tiered pricing, a sample COA and a 3D mockup, and every order ships with its lot documentation and FBA-ready labeling.
