According to the regulations of the European market, Amazon sellers who sell medical beds need to undergo CE certification. CE certification is a legal requirement of the European Common Market to ensure that products meet European safety, health and environmental protection standards. Medical beds are medical devices, so they need to pass CE certification to prove that they meet relevant technical requirements and safety standards. This is to protect the rights and interests of consumers and ensure that the products they use are safe and reliable. Therefore, if you sell medical beds on Amazon, you need to make sure that your product has passed CE certification.
