For lower‑risk Class I devices, appeals usually succeed when they clearly prove the product is 510(k)‑exempt and correctly classified. Focus on attaching concrete evidence: FDA establishment registration printout, device listing page, the specific 21 CFR citation showing exemption, manufacturer LOA, invoices, and clear packaging photos with labeling, then explicitly show which risky words or claims were removed from the listing. Structured, factual Plans of Action built around “root cause → fix → prevention” tend to have a high reinstatement rate for genuine Class I devices.
For high‑risk, Class III‑type devices, treat standard appeal channels as limited and route requests to Amazon’s professional healthcare/medical contacts (such as the Professional Healthcare Program email) wherever available. Include the full FDA Premarket Approval (PMA) letter or public summary, proof of FDA establishment registration and device listing, and any clinical or technical summaries that align your exact model with the approved PMA. Even with perfect documentation, reinstatement odds are much lower than for Class I, because Amazon’s default policy is to block Class III‑level risk unless handled through specialized programs.
