Necessity of met
1. Significantly reduce the cost of certification testing. Met uses a flat organizational structure to manage the operation of the company, which greatly reduces the management cost. Therefore, it has more cost advantages in product certification and higher cost performance. 2. Significantly reduce the cost of factory inspection. Met, as a customer-oriented certification company, did not adopt the measure of "fine" when finding abnormal items in factory inspection. At the same time, met advocates the humanized factory inspection mode, and gives customers more factory guidance! 4. Reduce the effort of certification. Met can provide technical guidance to customers, so that customers can quickly grasp the relevant product requirements. In this way, customers can greatly reduce the research energy on product technology.
5. Reduce the time spent on authentication. Met continuously improves the service process, greatly shortens the process time, and enables customers' products to have more time to market.
6. The customer fills in the application form and met provides the quotation

Factory inspection
The frequency of met certification factory inspection is twice a year except for products used in hazardous environment. The products used in hazardous environment are indicated in met report, and the corresponding factory inspection is 4 times a year. Since March 2009, at the request of the relevant U.S. government departments, all Chinese factories applying for certification have been changed to four inspections in the first year, and then twice a year thereafter.
