Currently, if selling products like hand warmers, mobile phone batteries, and chargers on Amazon, they must meet specific certification standards. If they do not comply with these standards, Amazon may revoke the seller's selling privileges. It is known that such products, if substandard, can easily cause fires, posing risks to public safety and property. Similar cases have occurred before! Since the UL standard is the American safety testing standard, Amazon, considering safety, will strengthen the control over electrified electronic products. Many products have been removed from shelves, which is understandable.
Admittedly, product certification is no longer a new topic, and Amazon's review process for electric products is particularly stringent. This time, Amazon's mass sending of the aforementioned emails serves more as a reminder to sellers. "To ensure consumer safety, Amazon always emphasizes that electric products must have relevant certifications before they can be sold. Electric products require a UL report issued by an approved laboratory."

UL Certification Introduction
UL is the abbreviation for Underwriter Laboratories Inc., a renowned testing laboratory. It is one of the largest independent, non-profit organizations in the world dedicated to public safety testing and certification. UL employs scientific testing methods to determine the safety and potential hazards of various materials, devices, products, equipment, and buildings. It establishes, writes, and distributes relevant standards and materials aimed at reducing and preventing losses to life and property, while also conducting field research. In summary, UL primarily focuses on product safety certification and the provision of safety assurance, aiming to contribute to the market's availability of goods with high safety standards and to ensure personal and property safety. As a means to eliminate technical barriers in international trade, UL plays a positive role in promoting the development of international trade.
UL was founded in 1894. Initially, UL was primarily supported by fire insurance departments to operate, until it became fully independent in 1916. Over nearly a century of development, UL has become a world-renowned certification body, with a comprehensive and rigorous organizational management system, standard development, and product certification procedures. Managed by a board of directors composed of representatives from safety experts, consumers, the education sector, utilities, and the standards department, UL's day-to-day operations are handled by the President and Vice Presidents. Currently, UL has five laboratories in the United States, with its headquarters located in the Northbrook town in the northern suburbs of Chicago, and corresponding laboratories have been established in Taiwan and Hong Kong.
