For UL certification, the certification prices for different products are different, and you need to provide product specifications before you can quote. The UL certification fee mainly consists of two parts: one is the initial testing fee, and the other is the later maintenance fee.

1. The initial testing fee is mainly charged according to the standard, so the charging standards for different products are also different. You need to provide us with the product for evaluation before we can quote. The cost of later maintenance is basically related to the number and frequency of our audits. UL certification requires four factory audits per year, one each in spring, summer, autumn and winter, so the cost is determined based on the number of times; there is also the UL mark fee.
