KC(KoreaCertification) certification? is a Korean electronic and electrical safety certification system, which is mandatory in Korea. Domestic or foreign manufacturers must obtain Korean safety certification before exporting electronic products to Korea. Since January 1, 2009, Korea electrical product safety certification is divided into mandatory certification and self-regulatory (voluntary) certification. Basically, electrical products whose input voltage range is AC voltage above 50 volts to less than 1000 volts need to accept safety certification, and lithium batteries are included in the KC certification catalogue as mandatory certification products.

MSDS (Material Safety Data Sheet), namely chemical safety technical specification, can also be translated into chemical safety specification or chemical safety data specification. It is a document used by chemical manufacturers and importers to clarify the physical and chemical characteristics of chemicals (such as PH value, flash point, flammability, reactivity, etc.) and the possible harm to users\' health (such as carcinogenesis and teratogenesis, etc.). In Europe, MSDS certification is also called SDS certification, SDS form, or MSDS certificate. Generally, it is used for documents required by the carrier in the process of transportation logistics.

Smart socket is a new type of safety socket, can automatically control the switch, mainly used in home, office and other places, and smart socket set up lightning, anti-high voltage, anti-overload and other functions, can automatically detect electrical current changes, abnormal can automatically power off, very intelligent and safe.
