1. Introduction of UL certification
UL is short for Underwriter Laboratories Inc. The UL Safety Laboratory is the most authoritative in the United States and the largest private institution engaged in safety testing and identification in the world. UL certification is a non-mandatory certification in the United States, mainly testing and certification of product safety performance.

2. UL certification mark
For different types of UL services, UL marks can be divided into three categories, LISTED listing marks, Classified classification certification marks, and Recognize parts certification marks. UL's services are not only based on American UL standards, but also Canadian standards (cUL). As a result, UL marks are also divided into three types for UL products and cUL products, as well as for both. The "us" at the bottom right of the UL mark means it is suitable for the United States, the "c" at the bottom left means it is suitable for Canada, and both "us" and "c" are suitable for use in both countries.
