Amazon supplement verification checklist for 2026

Before you start

Amazon notifies individual sellers of their own verification deadline directly, and that notice is the only authoritative deadline for your account, not a figure in any general guide, including this one. What follows is the order of work regardless of the specific date on your notice: what to gather, what to check, and how to keep it current once one SKU passes.

Who does what

Three parties touch this process, and confusing their roles is a common source of delay. The brand inventories, collects, and hands over; it never submits anything to Amazon directly. The manufacturer (or its contracted lab) produces the underlying documents: the cGMP certificate, the batch-specific COA, and any category-specific test results. The Amazon-approved TIC provider reviews what the brand hands over, verifies authenticity with the issuing lab, and is the only party that actually submits a result to Amazon. Knowing which party owns which step before you start prevents the most common cause of delay: waiting on a manufacturer for a document nobody explicitly asked for, or expecting a provider to chase a document the brand hasn't collected yet.

The checklist

1. Inventory every SKU and its active lots.
   • List every listing that needs verification, not just the ones you think of first.
   • For each SKU, identify the current production lot; a verification is done against a specific lot's documents, not the SKU in the abstract.
   • Note the manufacturer for each SKU. A brand using more than one contract manufacturer needs this mapped before collecting documents.
2. Collect the cGMP certificate and each lot's Certificate of Analysis.
   • The cGMP certificate covers the manufacturing facility, from a qualified third-party auditor. See what Amazon requires for supplement listings for the document set.
   • The COA covers the specific product and lot; a supplier's raw-material certificate does not substitute for finished-product results.
   • Ask your manufacturer for any category-specific testing your product type requires; not every SKU needs the same panel.
3. Check each document against the accepted document window.
   • Confirm the COA's certificate date, not the sample or test date, against your chosen provider's currently published window. See how long a COA is valid for Amazon for how that window is applied and why sources disagree on the figure.
   • If a document is close to aging out, treat it as already out: a review that starts today may finish after the window closes.
   • If Amazon's notice states a deadline for your account, work backward from that date, not from a general guide's figure.
4. Choose an Amazon-approved TIC provider.
   • Confirm current approval in Seller Central's provider selection; the list changes monthly.
   • Compare providers on turnaround, whether they run their own lab, and testing scope. See how to choose an Amazon-approved TIC provider and the free TIC provider comparison.
5. Hand the documents over.
   • Give the provider the complete set for the SKU: cGMP certificate, COA, and any category-specific results.
   • Match every unit on the COA to the supplement facts panel and confirm no field is left blank before sending. These are the most common reasons a review bounces.
   • You cannot submit to Amazon yourself; the provider reviews and submits the result directly.
6. Track it going forward.
   • A pass today is not permanent; the next lot needs its own current COA.
   • Run the free check against your uploaded COAs periodically to see which SKUs would pass a review today and which are approaching their window.
   • Set your own reminder ahead of each document's certificate-date window rather than waiting for a provider or Amazon to flag it.

Why this order, specifically

It's tempting to start by picking a provider, because it feels like the concrete first step. Working backward from a provider choice usually costs more time than it saves, because the provider's requirements only make sense once you already know which SKUs, which lots, and which manufacturers you're dealing with. Inventorying first means the document-collection step asks for exactly the right things from exactly the right people, once, instead of a second and third round of requests after a provider's review turns up what wasn't gathered the first time.

Where this checklist usually breaks down

• Treating the SKU as the starting point instead of the lot. A COA from an old lot doesn't cover the lot currently shipping, even if the SKU name hasn't changed.
• Collecting a supplier's raw-material certificate and assuming it stands in for finished-product testing, which a reviewer checking the label needs separately.
• Waiting for a provider's rejection to discover a document is outside the accepted window, instead of checking the certificate date before handover.
• Treating verification as a single project with an end date, rather than a recurring check tied to each new lot.

What good tracking looks like once you're through

Verification passing once is a snapshot, not a state. The same SKU, three lots later, is a new set of documents with a new clock. Compliant Always reads certificate dates off uploaded COAs on every plan, including free, and shows which SKUs would pass a review today. The paid plans add the 60/30/14-day warnings and the manufacturer chase before a document ages out unnoticed.
