MET necessity

1. Significantly reduce the cost of certification testing. MET manages the company's operations with a flat organization structure, which greatly reduces management costs. Therefore, it has more cost advantages in product certification and higher cost performance.

2. Significantly reduce factory inspection costs. MET, as a customer-oriented certification company, found that there was no “fine” measure for abnormal items in factory inspections. At the same time, MET promotes a humanized factory inspection mode, giving customers 3 and more factory guidance!

4. Reduce the energy spent on certification. MET can provide technical guidance to customers, so that customers can quickly master the relevant product requirements. In this way, customers can greatly reduce the research effort on product technology.

5. Reduce the time spent on certification. MET continuously improves the service process, greatly shortens the process time, and allows customers' products to have more time to market.

6. The customer fills out the application form and MET provides the quotation

Factory inspection

MET-certified factory inspections are conducted twice a year except for products used in hazardous environments. Products used in hazardous environments are indicated in the MET report, and the corresponding factory inspection is 4 times per year. Since March 2009, at the request of the relevant US government departments, all new Chinese factories applying for certification will be changed to 4 inspections in the first year, and thereafter 2 inspections each year.
