Introduction to UL Certification

UL is the abbreviation of Underwriter Laboratories inc. U safety laboratory is the most authoritative institution in the United States, and also a large non-governmental institution engaged in safety testing and identification in the world. It has a complete set of strict organization and management system, standard development and product certification procedures. The UL mark is a widely recognized mark that certifies that the product complies with the safety regulations of the United States. The logo is also officially recognized by Canadian provinces and regions.

UL certification is a non mandatory certification in the United States, mainly for testing and certification of product safety performance, and its certification scope does not include EMC (electromagnetic compatibility) characteristics of products.

In a word, it is mainly engaged in product safety certification and operating safety certification business. Its ultimate purpose is to obtain products with a fairly safe standard for the market and make contributions to the guarantee of human health and property safety. As an effective means to eliminate technical barriers to international trade, UL also plays an active role in promoting the development of international trade.

UL Certification FAQs

1. How long is the UL certificate valid?

UL certification has no validity period. UL reflects the situation of the applicant company by file number. As long as you inspect the factory on time every year and submit maintenance fees on time, UL certification will always be valid.

2. How long does it take to get UL certification?

The UL certification processing cycle takes about 2-3 months. The preliminary preparation is very important. The more timely and sufficient the enterprise information preparation, the shorter the UL certification cycle will be. If the product quality of the enterprise is good, the test can be passed smoothly, and the UL certification time can be greatly shortened.

3. How much is UL certification?

The UL certification fee is based on the product. There are great differences between different industries and product categories. Specific analysis of specific products is required, usually tens of thousands of yuan.

The UL certification fee is mainly composed of two parts: one is the early detection fee, and the other is the later maintenance fee. The early detection fees are mainly charged according to the standard, so the charging standards for different products are also different. We need you to provide the products for your evaluation before we can quote for you.

The cost of post maintenance is related to the number and frequency of UL certification audits. UL certification requires four factory audits each year, one in spring, summer, autumn and winter. The file maintenance cost, as well as the UL logo cost, will only incur later maintenance costs if the previous tests can be passed.

4. Does UL certification require factory inspection?

UL certification requires factory inspection. After the enterprise applies for UL certification for the first time, it can arrange shipment only after the first factory inspection. The purpose is to ensure that the products continue to meet the requirements of UL certification and that all products produced are consistent with the test samples.

For subsequent certification, it is not necessary to re ship the products from the factory with prior inspection. The annual inspection of UL is conducted once a quarter, and the factory inspection is conducted four times a year.
