Amazon Now Requires Third-Party cGMP Verification for Supplements: The 2026 Guide

Amazon spent years applying its third-party testing requirement to a short list of problem categories. That era is over. In an announcement to sellers on December 18, 2025, covered in detail by NutraIngredients, Amazon said it is extending third-party cGMP verification to all dietary supplements sold in its US store, rolling out in phases through 2026.

If you sell a multivitamin, a fish oil, a probiotic, anything with a Supplement Facts panel, this now applies to you. Here is what the requirement actually says, who the approved verifiers are, and what to do before Amazon's email lands in your inbox.

What changed in 2026

Since 2024, Amazon required third-party verification only for supplements in five high-risk categories: sexual enhancement, weight management, bodybuilding, sports nutrition, and joint health. Everyone else could sell on self-attestation and basic documentation.

The 2026 expansion removes that carve-out. As SupplySide Supplement Journal reports, all supplement sellers must now demonstrate two things through accredited third parties:

• Labeling compliance with the Food, Drug, and Cosmetic Act, meaning the label meets FDA requirements under 21 CFR 101.
• Manufacturing compliance with FDA's current Good Manufacturing Practice regulations, 21 CFR Part 111 (or Part 117 where applicable), verified by an Amazon-approved Testing, Inspection, and Certification organization, usually shortened to TIC.

The second part is the expensive one. It means the facility that makes your product needs a current third-party cGMP certification or audit, and the proof has to flow to Amazon through an approved channel, not as a PDF you upload yourself.

Who counts as an approved verifier

As of mid-2026, Amazon's approved TIC organizations are:

• NSF
• Eurofins
• UL
• SGS
• Intertek
• Merieux NutriSciences
• Certified Laboratories

Accepted cGMP certification programs include, but are not limited to, NSF/ANSI 455-2, UL GMP, USP GMP, Eurofins GMP, SQF Dietary Supplements Food Safety Code, and GFSI or SSCI benchmarked schemes. The details shift as Amazon adds partners, so confirm the current list with your TIC before paying for anything.

Just as important is what does not count. According to Certified Laboratories' summary of the policy, private audits, first-party audits, consulting audits, and FDA inspection records are not accepted. A clean FDA inspection of your co-manufacturer is nice to have, but it does not satisfy this requirement. The certificate must come from an accredited third party and must be current, not expired.

The 90-day window

Amazon is not flipping a switch for the whole catalog at once. The rollout is phased: sellers receive a notification, and from that point they typically have 90 days to initiate a documentation request with a TIC provider.

Read that carefully. The clock is about starting the process, but the practical deadline is harsher than it sounds, because a cGMP audit or certification review is not a 90-day project you control. If your manufacturer already holds a qualifying certification, verification is mostly paperwork between the TIC and Amazon. If your manufacturer holds nothing, a fresh NSF/ANSI 455-2 certification involves scheduling, an on-site audit, findings, and corrective actions. That routinely takes several months. Sellers who wait for the notification and then discover their co-man has no third-party certification are the ones who end up suppressed.

One mitigating detail: Amazon has said outreach may not be necessary where it can already verify compliance through its Compliance Fast-Track partners or public databases. If your products carry current certifications from NSF, USP, BSCG, GRMA, Informed, or Clean Label Project, Amazon may validate you automatically. Fast-Track does not, however, cover the separate finished-product testing that high-risk categories still require.

High-risk categories still have an extra layer

If you sell in sexual enhancement, weight management, bodybuilding, sports nutrition, or joint health, the expansion changes nothing about your existing burden. Those products must still pass finished-product testing to NSF/ANSI 173-2023, which verifies the product contains the ingredients claimed on the label and is free of specific undeclared contaminants. The cGMP facility verification stacks on top of that, it does not replace it.

What happens if you miss it

Amazon's enforcement pattern here is suppression and removal, not account deactivation. Listings without verified compliance stop being purchasable until the verification lands. That distinction matters less than it sounds: a top ASIN that goes dark for the three months a certification takes loses its rank, its reviews momentum, and often its Subscribe and Save base. If a listing does get pulled, our guide to diagnosing and fixing suppressed supplement listings covers the mechanics, but the honest answer is that prevention is the whole game with this policy.

What to do now, step by step

1. Ask your manufacturer what they hold, today. Request a copy of their current third-party cGMP certificate. Check the issuing body against Amazon's accepted programs and check the expiration date. If you use multiple co-manufacturers, do this per facility.
2. If they hold a qualifying certification, connect it to a TIC. Contact an approved TIC provider, open a documentation request, and have the TIC verify and transmit compliance to Amazon. Keep written confirmation.
3. If they hold nothing, start the certification conversation immediately. Either your co-man pursues NSF/ANSI 455-2 or an equivalent, or you move production to a facility that already has it. Both paths take months, which is exactly why waiting for Amazon's 90-day notice is a trap.
4. Check whether Fast-Track already covers you. Products certified by NSF, USP, Informed, BSCG, GRMA, or Clean Label Project may be validated automatically. Confirm in your compliance dashboard rather than assuming.
5. Get your document file in order. The TIC verification travels with your labels, Certificates of Analysis, and product documentation. Our rundown of the compliance documents every supplement seller should keep on file covers the full set.
6. Audit the listings themselves while you are at it. cGMP verification proves the factory. It does nothing for a detail page that claims 5,000 mg when the panel says 500. Amazon is running claims enforcement on a parallel track, and a listing that survives the TIC check can still be deactivated for a mismatched ingredient claim the same week.

The part you can fix this afternoon

You cannot certify a factory in a day. You can, however, make sure that when Amazon's systems look at your listings, the content gives them nothing to flag. VERID8 scans your listing text and images against FDA, FTC, and Amazon rules, catches the ingredient mismatches and restricted claims that trigger the other half of Amazon's 2026 enforcement, and writes a compliant fix for each finding. You can run one listing through it free while you wait for your manufacturer to dig out their certificate.

The sellers who come through this year cleanly will be the ones who treated the December announcement as the deadline, not the day Amazon's email finally arrived.
