New-seller gate check · For readers with no Amazon account yet
Protein powder sits inside the supplements gate — same verification, same documents — with two product-specific traps: label protein claims are checked against the lab report, and allergen labeling (whey, soy, milk) is read closely. Here is the new-account version of the answer.

Approval required first — with the exact documents below
Treat protein as supplements with extra label scrutiny. If the numbers on the tub are not the numbers in the lab, stop before Amazon finds it for you.
Your model changes this answer. For reselling established brands, homemade / home-produced, used / secondhand goods, the verdict is different — run the checker below with your situation and read the verdict it prints.
This verdict is category-level, from Amazon's published requirements, last verified October 21, 2026. Brand-level gates change weekly and vary per account — no honest site can list them, so we don't pretend to. Amazon decides per account; this is the published requirement set, not a promise of approval.
Your own protein brand with real lab paperwork: a hard but real path. Reselling the big tubs from the supplement aisle: effectively closed — the brands verify at brand level and police their listings, and your day-one account brings neither authorization nor history.
| Document | What it has to be |
|---|---|
| Certificate of Analysis per product | ISO/IEC 17025 lab report covering identity and potency — the protein-per-serving number on your label is checked against it. |
| cGMP certification of the manufacturer | 21 CFR 111 manufacturing certificate from whoever actually blends and fills the tubs. |
| TIC third-party verification | Mandatory for supplements since April 2, 2024, arranged through Amazon's approved TIC organizations. |
| Label photos, all panels | Supplement Facts, allergen statement (milk/soy/egg where applicable), and net weight — all legible. |
| Commercial invoices (resale path) | 10+ units within 180 days from the manufacturer or authorized distributor. |
The verdict for Protein powder & sports nutrition depends on how you would sell. Pick your model — the gate answers differently.
$700–$2,000 — Same economics as the supplements gate: testing and TIC verification per SKU, Professional plan during the application, and a compliant first production run. Planning range, not a quote.
The checker gives you the gate. The Amazon Entry Kit gives you the paperwork: the per-category document checklists for all 22 gates on this site, the invoice-readiness worksheet, the starter ladder plan, the application-order playbook, and the rejection-recovery steps for when Amazon says no the first time.
Included in the $39 Amazon Entry Kit
Yes — it is gated and verified as a dietary supplement, with the TIC process on top.
Same gate. Vegan blends still need COA, cGMP and TIC verification, plus allergen labeling for soy and other declarable ingredients.
Yes — and you should. Testing is per product, so one flavor keeps the verification bill at one line while you learn the category.
Not sure Amazon is even your first door? The free Door Finder at our family hub, FirstDoorCheck, compares all seven doors from your starting point — and is allowed to tell you a different door fits better, because it doesn't take money from platforms either.
