Amazon Category/Listing approval guidance

Please know that Amazon's internal teams will be the final deciding authority and we cannot influence their decision. Being a Team Leader at Amazon Seller Support(now Partner Support) for 5 years I understand Amazon systems and can definitely take a look at your product, documents, approval process followed and make appropriate suggestions or guide you through the process.

NOTE: If its a PPE then there would be some additional approvals required.
