At present, if there are hand warmers, mobile phone batteries, chargers or other live products sold on the Amazon website, they must meet the specified certification standards. If these standards are not met, Amazon may revoke the seller's sales authority. It is understood that if such products are unqualified, it is easy to cause fire and endanger people's lives and property safety. Similar cases have occurred before! Since the UL standard is also the safety testing standard in the Americas, Amazon will strengthen the control of live electrical and electronic products for safety reasons, and many products have been removed from the shelves, which is reasonable.

It is undeniable that product certification is no longer a new topic, and Amazon's review of live products is even more stringent, and the large number of the above-mentioned emails sent by Amazon this time is more of a reminder for sellers. "In order to ensure the safety of consumers, Amazon always emphasizes that live products need to have relevant certification before they can be sold, and live products need to be issued by a laboratory accredited by ILAC ISO 17025 or NRTL authorized standards.
