How does TIC verification work and what does it cost?
By Jake, founder · Published · Updated
TIC verification is a four-step flow: the seller chooses a provider from Amazon's current approved list, hands over the document set, the TIC reviews it and confirms authenticity with the issuing laboratory, and the TIC submits the result directly to Amazon. Reviewing an existing current COA costs roughly $80 to $120 per product; fresh testing costs roughly $500 to $1,000.
TIC verification is the channel through which every dietary supplement listing on Amazon is now validated. The flow is short, but each step has a failure mode, and the cost of the whole exercise is decided before it starts, by the state of the seller's documents.
The flow, step by step
- The seller chooses a provider.From Amazon's current approved TIC provider list in Seller Central, current being the operative word, since the list changes frequently. The choice of provider is the seller's; the requirement that it come from the approved list is Amazon's.
- The seller hands over the document set.Typically the cGMP certificate for the manufacturing facility and the Certificate of Analysis for the product, plus finished-product testing where the category requires it. This handover is the seller's entire active role in the flow.
- The TIC reviews and verifies authenticity.The provider checks format and content (currency, completeness, units, accreditation) and contacts the issuing laboratory directly to confirm the document is genuine and unaltered. This authenticity step is why a COA must carry the lab's contact details: a document the provider cannot verify with its issuer cannot pass.
- The TIC submits the result directly to Amazon.The seller does not upload anything and has no channel to. The verification outcome travels from provider to Amazon; the seller sees the result in the listing's status.
What it costs
| Scenario | Approximate cost per product | What drives it |
|---|---|---|
| Current COA exists | $80 to $120 | Documentation review only: the TIC checks and verifies an existing document. |
| No current COA | $500 to $1,000 | Fresh third-party testing must be commissioned before any review can happen, adding laboratory turnaround measured in weeks. |
Cost figures last verified 2026-07-24, from published TIC provider and third-party laboratory price sheets. They are configuration, not constants: providers change their pricing.
The gap between the two rows, several hundred dollars per product per cycle, is the entire economics of supplement document management. Nothing about the product changes between the rows; only whether a usable document existed on the day it was needed.
The seven reasons submissions bounce
Providers reject document sets for a short, stable list of mechanical defects. In reported practice the recurring ones are:
- A stale COA. Outside the accepted age window, the strictest reported window being 182 days, and therefore unusable regardless of content.
- Units that do not match the supplement facts panel. A reviewer cannot reconcile results stated in one unit against a label stated in another.
- Missing accreditation reference. No identifier tying the laboratory to its accreditation for the methods reported.
- Missing laboratory contact details. Without them the authenticity call to the issuing lab cannot be made.
- Incomplete fields. Absent lot codes, dates, methods, or results lines, meaning anything that leaves a column of the results table empty.
- Wrong file format.Files the provider's intake cannot process, including image-only scans of degraded quality.
- Documents that cannot be tied to the product. A lot code or product name that does not match the listing under review.
The pre-submission checklist
The checklist worth running before any handover is simply the bounce list inverted. Confirm, for each product:
- COA issue date inside the accepted window, with margin for the provider's queue.
- Every result's unit matching the supplement facts panel.
- The laboratory's accreditation reference present on the document.
- The laboratory's contact details present and current.
- No empty fields: lot code, dates, analytes, results, units, methods all populated.
- A clean, readable file in a format the provider accepts.
- Lot code and product name matching the listing being verified.
Seven checks, each answerable in under a minute with the document in hand. A set that passes all seven converts the verification from an open-ended correspondence into a single handover, which is the only part of the flow the seller ever controlled.
Document-age window applied here: 182 days, the strictest reported value; other sources report 274 and 365 days. Last verified 2026-07-24. This is provider policy, not regulation, so confirm the current figure with your TIC provider before relying on it.
Frequently asked questions
- What is a TIC provider?
- TIC stands for Testing, Inspection and Certification. In Amazon's supplement verification model, TIC providers are the third-party firms Amazon has approved to review sellers' compliance documents, verify their authenticity with the issuing laboratories, and submit verification results directly to Amazon.
- How much does TIC verification cost per product?
- Documentation review of an existing, current COA runs roughly $80 to $120 per product. If no current COA exists, third-party finished-product testing runs roughly $500 to $1,000 per product before the review can happen. Figures last verified 2026-07-24.
- Why do TIC submissions get rejected?
- For mechanical, checkable reasons: a stale COA outside the accepted age window, units that do not match the supplement facts panel, a missing laboratory accreditation reference, missing lab contact details, incomplete fields, or a file format the provider cannot process.
- Does the seller submit anything to Amazon during TIC verification?
- No. Under TIC Direct Validation the provider submits the verification result directly to Amazon. The seller's role ends at the handover: choosing an approved provider and giving it a current, complete, correctly formatted document set.
