American UL

1. Introduction to American UL certification

UL is short for Underwriter Laboratories Inc. (Underwriter Laboratories Inc.). The UL Safety Testing Institute is the most authoritative in the United States and the largest private organization engaged in safety testing and identification in the world. UL certification is a non-compulsory certification in the United States, mainly for product safety performance testing and certification, and its certification scope does not include the EMC (electromagnetic compatibility) characteristics of the product.


According to UL's different types of services, the UL mark can be divided into three categories, LISTED listed mark, Classified certification mark, and Recognize component certification mark. UL's services are not only based on the American UL standard, but also based on the Canadian standard (cUL). Therefore, the UL mark is also divided into UL products and cUL products, and both meet these three. The "us" at the bottom right of the UL logo means it is applicable to the United States, and the "c" at the bottom left means it is applicable to Canada, and both "us" and "c" are applicable to both countries.


The North American market has the most advanced and complete product testing standards, and higher requirements for product testing and certification. In order to seize the American market, Chinese electronic and electrical products must overcome these testing and standard constraints.

4. UL certification fee is mainly composed of two parts:

The first is the initial testing costs. The preliminary inspection fee is mainly charged according to the standard, so the charging standards for different products are also different. The specific price requires you to provide product information, and the engineers of Virtue Testing can give you a quotation after evaluating it for you.

The second is the cost of later maintenance. Post-maintenance costs include factory inspection costs and annual fees. UL certification requires four factory audits a year, one in spring, summer, autumn and winter.
