We verify and format required Certificates of Analysis for dietary supplements, cosmetics, and topical products on Amazon — checking lab testing details against Amazon’s strict compliance thresholds prior to portal submission.
Amazon’s compliance thresholds for supplements, cosmetics, and topical products are more specific than general lab safety standards — a Certificate of Analysis that’s completely valid from the lab’s perspective can still be rejected if it doesn’t cover the exact parameters or formatting Amazon’s category safety team requires.
Suppressions triggered by COA issues often hit an entire product line at once, since the same lab documentation gap tends to apply across every SKU that shares it.
Certificates of Analysis reviewed against Amazon’s specific category thresholds before submission.
Test parameters checked to confirm they cover exactly what Amazon requires for that product category.
Documentation formatted to submit cleanly through Amazon’s compliance portal, avoiding format-based rejections.
Issues caught before submission, preventing the listing suppressions that incomplete COAs commonly trigger.
One clear scope for supplements, cosmetics, and topical products.
Documentation that clears Amazon’s review the first time.
The existing Certificate of Analysis checked against Amazon’s specific category compliance thresholds.
Any missing parameters or formatting issues identified before submission, not discovered after a suppression.
Documentation prepared in the exact format Amazon’s compliance portal requires for clean submission.
The COA submitted and confirmed as accepted, resolving or preventing listing suppression.

Timeline: review and formatting of an existing COA typically takes 1–2 business days; if new lab testing is required to meet a specific parameter, timeline depends on the lab’s turnaround.
Category-specific, not generic. We check against Amazon’s exact thresholds for your product category, not general lab standards.
Caught before submission. Gaps are identified proactively, preventing the suppression a rejected COA would cause.
Formatted for the portal. Documents are prepared to submit cleanly, avoiding format-based rejections.
Consistent across your line. Multi-SKU consistency is checked, since one gap often applies across an entire product line.
A verified COA keeps your listing from being suppressed — but GMP documentation is often required alongside it for the same product categories.
Before: A supplement line was suppressed across several SKUs simultaneously, with the same COA gap affecting all of them.
Diagnosis: The original Certificate of Analysis was missing a specific heavy metals testing parameter Amazon’s supplement category requires.
Fix: Identified the missing parameter, coordinated with the lab to obtain the additional testing, and resubmitted a complete COA.
Result: The suppression was lifted across the entire product line once the corrected documentation was accepted.
Before: A cosmetic brand launching a new product wanted to avoid the suppression risk of an incomplete COA from the start.
Diagnosis: The brand’s lab had provided a general safety certificate that didn’t specifically map to Amazon’s cosmetic category requirements.
Fix: Reviewed the lab documentation against Amazon’s specific cosmetic thresholds before the listing went live, catching the gap early.
Result: The corrected COA was submitted proactively, and the new listing launched without ever triggering a suppression.
Before: After one suppression, a brand wanted to check whether the same issue existed across its broader supplement catalog.
Diagnosis: The same lab documentation template had been used across the whole catalog, meaning the identified gap likely existed everywhere.
Fix: Conducted a catalog-wide COA compliance audit, identifying and correcting the same gap across every affected SKU.
Result: The brand avoided a cascade of future suppressions by fixing the underlying documentation gap proactively across its full catalog.

What people mostly ask us about Amazon COA compliance and what you might wanna know –
A lab document verifying a product’s composition, purity, and safety, required by Amazon for supplements, cosmetics, and topical products.
Lab documentation verification, category threshold compliance checking, and portal-ready formatting — see the full scope above.
Most suppressions happen because the COA doesn’t cover the specific parameters or formatting Amazon’s category requires, even if it’s a valid lab document generally.
We review and verify existing documentation; if new testing is needed to meet a specific requirement, we coordinate with your lab on what’s needed.
Yes, multi-SKU consistency review is part of the standard scope, since documentation gaps often apply across a full line.
Reviewing and formatting an existing COA typically takes 1–2 business days; new testing timelines depend on the lab.
Dietary supplements, cosmetics, and topical products are the most common categories requiring Amazon-specific COA compliance.
Yes, catalog-wide compliance auditing and ongoing monitoring are part of the standard scope.
Yes, as a separate but closely related service, often needed alongside COA compliance for the same product categories.
