Where is the authoritative list of Amazon-approved TIC providers?

Inside Amazon Seller Central, under "Select a Provider" for dietary supplements. Amazon updates that list monthly. Third-party comparisons, including Compliant Always's, are verified snapshots, so always confirm current approval status in Seller Central before choosing.

Do all TIC providers also run their own testing lab?

No. As of 2026-08, Certified Laboratories' own page states it "does not perform cGMP facility audits: we only verify cGMP documentation provided by your third-party auditor," alongside separately offered lab testing. Mérieux NutriSciences describes operating its own accredited laboratory network. Confirm which mode a provider offers before assuming both.

Is TIC provider pricing published anywhere?

Rarely, per-provider. Most providers direct sellers to request a quote. Global cost ranges for document review versus fresh testing are tracked at https://compliantalways.com/compare-tic-providers alongside per-provider price notes where a provider has published one.

What document-age window should I plan around before choosing a provider?

Providers publish differing document-age windows for how old a certificate of analysis (COA) can be and still be reviewed; the strictest reported figure is 182 days. Confirm the specific provider's current window directly, since it's provider policy rather than a fixed Amazon rule.

How do I prepare documents so a review passes on the first try?

Match every result's unit to the supplement facts panel, include the lab's accreditation reference and contact details, fill every field, use a clean readable file format, and make sure the lot code and product name on the document match the listing being verified.

How to choose an Amazon-approved TIC provider for supplements

By Jake, founder · Published 2026-08-17 · Updated 2026-08-17

Choosing an Amazon-approved TIC provider comes down to five checkable things: approval for your specific seller role, turnaround, whether they run their own testing lab or only review documents, testing scope, and communication. Amazon maintains the authoritative approved list inside Seller Central and updates it monthly, so no third-party page, including this one, is the source of truth.

Start with Amazon's own list, not a comparison page

Amazon maintains the authoritative approved-provider list in Seller Central (Select a Provider) and updates it monthly. This table is a verified snapshot, not the source of truth. Any comparison of providers, this article included, is a snapshot verified on a given date, not a live feed. Before requesting a quote, confirm the provider is currently listed for your specific seller role in Seller Central's "Select a Provider" flow; approval and category coverage can change between snapshots.

What actually differs between providers

Reading provider pages side by side surfaces real differences, not just brand names. Three fetched for this article, as of 2026-08, illustrate the range:

Certified Laboratories states plainly that it "does not perform cGMP facility audits: we only verify cGMP documentation provided by your third-party auditor," while separately offering lab testing. That is a document-review-plus-testing combination, not a facility auditor.
Mérieux NutriSciences describes operating its own network of ISO/IEC 17025:2017 accredited laboratories and verifying that "the issuing laboratory holds a valid ISO/IEC 17025:2017 accreditation" on documents it reviews: testing and document verification under one roof.
Eurofins emphasises a "dedicated Client Services Specialist, guiding you through every step of the process" and operating "ISO 17025 accredited laboratories" that tailor methods "to your products' unique matrix requirements": communication and testing scope stated as a selling point.

None of the three pages reviewed publishes a turnaround time in days, and none publishes per-product pricing directly on the page fetched.

The five criteria, checked in order

What to check before choosing a provider
Criterion	What to check	Why it matters
Amazon approval for your role	Currently listed in Seller Central for your specific seller / category combination	A provider approved for one role or category isn't automatically approved for another
Turnaround	Ask directly; not reliably published on provider pages	Determines whether a near-expiry COA can be reviewed before it ages out
Published pricing	Check https://compliantalways.com/compare-tic-providers for what's publicly cited; otherwise request a quote	Most providers quote per product and per category rather than publishing a rate card
Runs its own lab, or documents only	Some providers (e.g. Certified Laboratories) separate document verification from facility auditing; others (e.g. Mérieux NutriSciences) run their own accredited labs	Determines whether the same provider can handle both a document review and fresh testing without a handoff
Testing scope	Which categories and analyte panels the provider actually tests, per its own page	Not every provider covers every supplement category to the same depth
Communication	Whether the provider names a dedicated point of contact or a self-serve portal	Affects how quickly a borderline document gets resolved instead of silently rejected

Why "approved for your role" isn't automatic

Amazon's dietary-supplement verification applies across different seller setups, and a provider's approval can be scoped to a specific role or product category rather than blanket coverage. The only reliable way to confirm a provider covers your situation is Seller Central's own provider-selection flow at the point you're actually requesting verification, not a marketing page and not a comparison table, including Compliant Always's own. Treat every third-party list as a starting point for research, then confirm inside your own account before committing.

Why turnaround matters more than it looks like it should

None of the provider pages fetched for this article states a turnaround time in days, which means it has to be asked directly and compared across quotes. Turnaround matters disproportionately here because of the document-age window: a COA sitting at, say, 20 days from its provider's cutoff can still fail if the review itself takes longer than that margin. A provider's price and scope can look identical to a competitor's and still produce a different outcome purely because one queue moves faster than the other.

Getting a quote without wasting a round-trip

Since none of the providers reviewed here publish per-product pricing, a quote request is the fastest way to get comparable numbers, but only if it's specific. Naming the exact product category, whether you need document review only or fresh testing, and how many SKUs are involved lets a provider quote accurately on the first pass instead of a back-and-forth that eats into the same document-age window you're trying to stay inside.

Use the free comparison tool as a starting point

Compliant Always's free TIC provider comparison tracks, for each Amazon-approved provider it lists, whether the provider offers document validation, fresh testing, or both, and cites a public source confirming its approved status, last verified 2026-07-24. No provider on this page pays us. There is no affiliate arrangement, referral fee, or commercial relationship with any testing or certification provider — and there never will be. Our product's entire value is that its compliance judgments are uncompromised; taking money from a provider we might point you toward would destroy that. The figures on this page are typical ranges, not quotes. Prices vary by product, category and provider — request quotes directly from the providers.

How to prepare documents so a review passes the first time

Providers reject document sets for mechanical, avoidable reasons far more often than for substantive ones. Before handing anything over:

Confirm the COA's certificate date is inside the provider's current document-age window, with margin for their queue. The strictest reported figure across providers is 182 days.
Match every analyte result's unit to the supplement facts panel exactly; a reviewer cannot reconcile mismatched units.
Confirm the issuing laboratory's accreditation reference and contact details are present, because the provider verifies authenticity directly with the lab.
Check every field is filled: lot code, dates, methods, results, units. An empty cell in the results table is a common rejection reason.
Use a clean, readable file in a format the provider's intake accepts, not a degraded scan.
Confirm the lot code and product name on the document match the listing under review.
