The Taiwan NCC (National Communications Commission) mark is a certification mark issued by the NCC, which is the regulatory body responsible for overseeing and regulating the telecommunications and broadcasting industries in Taiwan. The NCC mark is used to certify that a product meets the regulatory requirements for electromagnetic compatibility, safety, and other technical specifications in Taiwan. The mark is mandatory for certain categories of products, including wireless devices, telecommunications equipment, and radio equipment. If a product falls within the scope of the NCC regulations, it must be tested and certified by a designated testing laboratory in Taiwan before it can be legally sold or used in the country. Once a product has been certified, it can display the NCC mark on its packaging or documentation to indicate compliance with the relevant regulations.
