Amazon Supplement Approved Lab List — What Labs Amazon Actually Accepts

Quick answer

There is no official "Amazon approved lab list." I wish there was. It'd make life a lot easier.

What Amazon actually cares about: your Certificate of Analysis (COA) comes from a third-party ISO/IEC 17025 accredited lab that used a validated method — and the lab's accreditation scope actually covers the test they ran.

That last part trips people up constantly. A lab can be ISO 17025 accredited but not for every test. If your COA shows a test outside the lab's scope, Amazon's documentation team will reject it.

LabQuotes helps you find labs whose accreditation scope actually matches your product and required tests. No guesswork.

What Amazon actually wants from a lab

Amazon's supplement compliance documentation request is intentionally vague. They don't name specific labs. Instead, they set standards:

The lab must be independent and third-party — meaning no financial ties to the manufacturer, no shared ownership, no in-house QA lab.

The lab must hold ISO/IEC 17025 accreditation from a recognized accreditation body.

The COA must reference a validated test method — USP, AOAC, ISO, or an internally validated method the lab can defend.

The lab's name, address, and accreditation details must clearly appear on the COA.

The COA must match the exact product, lot number, and manufacturing date you're listing.

⚠️ Note

A COA from your contract manufacturer's in-house lab will get rejected. Amazon's policy explicitly states the lab must be independent and third-party. Even if the manufacturer has ISO 17025, the conflict of interest kills it.

Accreditation bodies Amazon accepts

Amazon doesn't publish a whitelist, but based on thousands of successful COA submissions, here are the accreditation bodies that consistently pass:

In the United States:

• A2LA (American Association for Laboratory Accreditation)
• ANAB (ANSI National Accreditation Board)
• PJLA (Perry Johnson Laboratory Accreditation)
• IAS (International Accreditation Service)
• NVLAP (National Voluntary Laboratory Accreditation Program) — limited scope

In Europe:

• UKAS (United Kingdom Accreditation Service)
• COFRAC (France)
• DAkkS (Germany)
• ENAC (Spain)
• ACCREDIA (Italy)

In Asia:

• CNAS (China)
• JAB (Japan)
• KOLAS (Korea)
• NABL (India)

In Canada and elsewhere:

• SCC (Standards Council of Canada)
• NATA (Australia)
• IANZ (New Zealand)

The key thing: the accreditation body must be an ILAC MRA signatory. That's the mutual recognition arrangement that makes cross-border COAs acceptable. If the lab's accrediting body isn't an ILAC signatory, expect a rejection.

Why in-house manufacturer labs get rejected

I see this constantly. A brand submits a COA from their contract manufacturer's lab, and it gets rejected within hours.

The reason is straightforward: Amazon views manufacturer-owned or manufacturer-affiliated labs as conflicted. Even if the lab is competent and ISO-accredited, the report is not independent.

Think about it from Amazon's perspective. If a supplement manufacturer can test its own products and declare them compliant, there's zero third-party verification. That defeats the entire purpose of requiring a COA.

The fix is simple: send your retained samples to a completely independent third-party lab. Not your manufacturer's "sister company." Not their "partner lab." A genuinely separate entity with different ownership.

How to check if a lab's accreditation actually covers your test

Here's the step-by-step that most people skip:

1. Get the lab's ISO 17025 certificate number.
2. Go to the accreditation body's website (A2LA, ANAB, etc.).
3. Search the lab's scope of accreditation.
4. Look for the specific test method you need — by method number or analyte.
5. If the test isn't listed, the COA might get rejected even if the lab is accredited.

💡 Note

I check every lab's scope before submitting a request through LabQuotes. Half the time, a lab I thought could run a test turns out to be accredited for a different version of the method. The details matter.

Common lab-credential rejection reasons

Here's what Amazon's documentation team actually flags, based on seller reports:

Lab not third-party. Manufacturer's own QA lab or an affiliated entity. Instant rejection.

Accreditation expired. ISO 17025 certificates have renewal dates. If the cert lapsed, the COA is invalid.

Test outside scope. The lab is accredited, but not for the specific test on your COA. Very common with heavy metals and pesticides.

Missing lab identifier. The COA doesn't show the lab's accreditation number or certifying body. Amazon needs both.

Vague method reference. If the method just says "in-house" or "proprietary" without a validated reference, it's a gamble.

COA looks templated. Generic-looking COAs with no lab letterhead, no signature, no unique report number get extra scrutiny.

Name mismatch. The lab name on the COA doesn't match the name on the accreditation certificate.

Wrong product identifiers. The product name, lot number, or date on the COA don't match what you're listing.

Does Amazon ever name acceptable labs?

Rarely, and only by accident. Sometimes a Seller Support rep will mention a lab in a case response, but those names aren't official and can change.

Amazon has at times referenced:

• Eurofins
• SGS
• Intertek
• NSF International
• Microbac
• Certified Laboratories

But here's the thing: Amazon isn't endorsing these labs. They're just examples of national testing chains that typically meet their criteria. A small independent lab with proper ISO 17025 accreditation is equally acceptable — often cheaper and faster too.

What to ask the lab before paying

Before you spend money on testing, ask the lab these questions:

1. "Can you send me your ISO 17025 scope of accreditation PDF?"
2. "Does your scope specifically list the method I need for this product?"
3. "Will your company name, address, and accreditation number appear on the COA?"
4. "Are you financially independent from the manufacturer?"
5. "What format will the COA be delivered in — PDF, editable, digitally signed?"
6. "What's your turnaround time for this test, and can you rush it?"

If a lab hesitates on any of these, walk away. A legitimate accredited lab answers these questions daily.

Quick Reference

Lab Category Matching

Amazon compliance testing typically falls under:

• Identity, potency, and purity per USP monographs
• Heavy metals per USP <2232> or equivalent
• Microbiology per USP <2021>/<2022> or equivalent
• Stability/shelf-life if making expiration claims

Real Methods Explained

What Sample to Send

Most labs need 50-100 grams or 10-20 finished units. Ask the lab for their specific sample submission form — different tests may need different quantities.

Expected Turnaround Time

Standard COA testing: 5-10 business days. Rush service: 2-5 business days at 1.5x-2x cost. Add time for sample shipping.

Accreditation Notes

Must be ISO/IEC 17025 from an ILAC MRA signatory body. Scope must include the specific test methods on your COA. Certificate must be current (not expired).

Price Ranges

Basic COA (heavy metals + micro + one assay): $300-$600. Full panel with pesticides and multiple assays: $800-$2,500. Rush fees add 50-100%.

Country/Region Targeting

U.S. market: A2LA, ANAB, PJLA, IAS. European market: UKAS, COFRAC, DAkkS. Multi-market sellers should verify mutual recognition coverage.

FAQ

Q: Does Amazon have an official approved lab list?

No. Amazon does not publish or maintain any official list of approved testing labs. They specify requirements — third-party, ISO 17025 accredited, validated methods — but you pick the lab.

Q: Can I use my manufacturer's in-house lab for Amazon compliance?

No. Amazon explicitly requires the lab to be independent and third-party. Manufacturer-owned labs, even if ISO-accredited, are considered conflicted and your COA will be rejected.

Q: How do I prove my lab is ISO 17025 accredited?

Ask the lab for their accreditation certificate PDF and scope document. Submit those alongside your COA. The COA itself should also display the lab's accreditation number.

Q: What happens if Amazon rejects my lab's credentials?

Amazon will send a notification specifying the reason. You'll need to address the issue and resubmit — either with a corrected COA from the same lab or a new COA from a different lab. The review queue resets, so you lose time.

Q: How recent does a COA need to be for Amazon?

Amazon typically expects a COA dated within the last 12 months for the specific product lot you're listing. Older COAs for different lots won't match your listing and will get flagged.
