Which of the following represent a best practice when selling on Amazon to ensure compliance with our policies:
Assign one or more employees to be responsible for reviewing each product you plan to sell. This employee should have deep and up-to-date knowledge of the products as well as the industry, including laws applicable to those products.
Carefully review our Restricted Products policy, including the "Examples of Prohibited Listings", and your product catalog on a regular basis. This includes any products that are included in inventory feeds or uploaded using an automated system.
If buying inventory from a source other than the manufacturer, apply extra diligence to understand the provenance of the products and the legal framework in which they may be sold.
When in doubt about whether a product may be sold, do not list it.
If selling drugs or supplements, understand the ingredients in these products and research whether they are permitted.
All of the above.
