First, the United States UL certification introduction

UL is a shorthand for Underwriter Laboratories Inc. The UL Safety Laboratory is the most authoritative in the United States and the largest private institution in the world for safety testing and identification. UL certification is a non-mandatory certification in the United States, mainly for the detection and certification of product safety performance, and its certification scope does not include the EMC (electromagnetic compatibility) characteristics of the product. For different types of UL services, the UL Mark can be divided into three categories, the LISTED listing mark, the Classified classification certification mark, and the Recognize part certification mark.

Second, the importance of battery UL certification

(1) The entire US market pays great attention to product safety; Amazon US Station also mandates that certain products must have UL certification; consumers and purchasers will choose products with UL certification mark when purchasing products.
(2) UL history has more than 100 years. The image of security is deeply rooted in consumers and the government. If you do not sell products directly to consumers, the middlemen will also require the products to have UL certification marks to make the products sell well.
(3) American consumers and purchasers are more confident in the products of the company.
(4) The federal, state, county, and municipal governments of the United States have more than 40,000 political districts, and all recognize the UL certification mark.
