Product safety is an important concern for Amazon and all retailers. A product that poses a safety risk to customers can cause injury or harm, and it is the responsibility of retailers to ensure that the products they sell are safe for use.
There are many different factors that can contribute to a product being deemed unsafe. For example, a product may have a design flaw that makes it prone to breaking or malfunctioning, it may contain hazardous materials or chemicals, or it may not meet safety standards set by Amazon.
Amazon can raise a safety concern for a product at any time if they become aware of a potential issue. This could be due to customer complaints or internal testing and monitoring. If Amazon identifies a safety concern with a product, it may take action such as removing the product from its website, issuing a recall, or contacting the manufacturer to address the issue.
