　　What is the UL certification, then?

UL Certification is a voluntary safety certification in the U.S., requiring product testing and factory audits, with quarterly audits four times a year and an annual audit, plus the cost of the UL file number fee. The expenses are high and the process is time-consuming, making it difficult for many small and medium-sized traders and factories to afford the high certification testing fees and subsequent maintenance costs.
