Everything you need to know
Amazon has progressively tightened its documentation requirements for dietary supplement listings. Sellers who don't have proper third-party COAs face listing suspensions, account holds, and escalating appeals processes. This guide explains exactly what Amazon looks for and how to stay compliant.
Does Amazon require third-party testing for dietary supplements?
Yes — Amazon increasingly requires third-party analytical testing documentation for dietary supplements, particularly in these situations: new supplement listings in competitive categories; product listing reviews following a complaint or safety concern; supplement products that fall into age-targeted categories (children's vitamins, infant products); and high-visibility enforcement sweeps targeting supplement categories. The specific tests required vary by product type and category, but heavy metals, microbial testing, and label claim verification (potency) are the most commonly requested.
What is a Children's Product Certificate (CPC) and when is it required?
A Children's Product Certificate (CPC) is required by the US Consumer Product Safety Commission (CPSC) for products marketed for children under 12 years old. For supplements marketed to children, Amazon requires a CPC supported by third-party testing from a CPSC-accepted lab. The CPC must document compliance with applicable children's product safety rules, including heavy metal limits. If your supplement label or imagery suggests it's for children, expect Amazon to require CPC documentation.
What does Amazon look for in a supplement COA?
Amazon reviewers typically look for: (1) Issuing laboratory — must be a genuine third-party lab (not the manufacturer's own lab), ideally with ISO 17025 accreditation; (2) Tested product — the COA must match the specific product ASIN and lot number; (3) Test date — COAs must typically be dated within 12–24 months; (4) Test results — quantitative results with acceptance criteria, not just pass/fail checkboxes; (5) Lab contact information — Amazon may directly verify the COA with the issuing laboratory.
Which heavy metals must be tested for Amazon supplement listings?
Amazon's heavy metals testing expectations for dietary supplements typically include the "Big Four": arsenic (As), cadmium (Cd), lead (Pb), and mercury (Hg), tested by ICP-MS. For children's products, compliance with CPSC's children's product rules applies, which reference stricter limits. Results should be reported in ppm or ppb with comparison to a recognized reference standard (California Prop 65 is commonly used as the benchmark in COAs provided to Amazon).
What happens if Amazon suspends my supplement listing?
Amazon listing suspensions for supplement compliance issues typically require: (1) obtaining or updating your third-party COA from an accredited lab; (2) submitting a Plan of Corrective Action (POCA) via the Appeals process; (3) uploading the new COA through the case management system. Response timelines vary from days to weeks. Some suspensions are resolved quickly with proper documentation; others may escalate to Account Health team review. Having a current, complete COA on file before a suspension is the best protection against prolonged listing downtime.
How often should I update my COAs for Amazon?
Amazon does not publish a specific COA renewal schedule, but the practical industry standard is to update COAs annually or with each new production lot. A COA that's more than 24 months old may be rejected during a review. For products with ongoing production, match each new production batch with a new COA showing that specific lot number. Keeping COAs current for every SKU reduces your exposure during category sweeps. Order a COA for your Amazon supplement listing.
