MET necessity
1. Significantly reduce certification testing costs. MET uses a flat organizational structure to manage the company's operations, which greatly reduces management costs. Therefore, it has more cost advantages in product certification and is more cost-effective.
2. Significantly reduce factory inspection costs. As a customer-oriented certification company, MET does not adopt "penalty" measures when abnormal items are found during factory inspections. At the same time, MET advocates a humanized factory inspection model to provide customers with more factory guidance!
4. Reduce the effort spent on certification. MET can provide customers with technical guidance to help them master relevant product requirements faster. In this way, customers can greatly reduce their research efforts on product technology.
5. Reduce the time spent on certification. MET continuously improves its service process, greatly shortening the process time and giving customers more time to market for their products.

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

Factory inspection

The frequency of MET certified factory inspections, except for products used in hazardous environments, is twice a year. Products used in hazardous environments are marked in the MET report, and corresponding factory inspections are conducted 4 times a year. Starting from March 2009, at the request of relevant U.S. government departments, all Chinese factories that newly apply for certification will be inspected four times in the first year, and will continue to be inspected twice per year thereafter.
