MET necessity

1. Significantly reduce the cost of certification testing. MET manages the company's operations with a flat organizational structure, which greatly reduces management costs, so 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, did not adopt "fine" measures when abnormal items were found during factory inspections. At the same time, MET advocates a human-friendly factory inspection model, 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 grasp the relevant product requirements. In this way, customers can greatly reduce research efforts on product technology.
5. Reduce the time spent on certification. MET continuously improves the service process, greatly shortening the process time, and giving customers more time to market.
6. The customer fills in the application form and MET provides a quotation


Factory inspection
MET certified factory inspections are performed twice a year, except for products used in hazardous environments. Products used in hazardous environments are marked in the MET report, and the corresponding factory inspection is 4 times a year. Beginning in March 2009, at the request of relevant US government departments, all new Chinese factories applying for certification were changed to four inspections in the first year and then twice a year thereafter.
