What are the costs of UL testing?

First of all, why do you want to do UL certification? (1) The entire US market pays great attention to product safety; 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. What are the fees (focus) included in the UL certification? Certificate fee + audit fee + file management fee + travel expenses for witness test (some testing agencies have) + UL label fee + testing service fee Among them, the audit fee is four times a year, about 2W RMB, and the file management fee is $1170 per year, which is collected by the UL agency. Then the focus is coming. Since some organizations will generate witness travel expenses and service fees, will it be left to the direct inspection by the UL agency? The answer is obviously not that simple. About 90% of the UL test can't be passed, and it needs to be retested and repaid. However, if it is sent to a private third-party agency for testing, there will be a pre-test, which will tell the customer where it is not qualified, so that it will be rectified, but UL will not, only two results: too or not. Therefore, most customers will choose a more insured way to be pre-tested by a third-party agency, and the application process will be fully managed by a third-party agency.
