Scope of mandatory CCC certification

Notes: a product may use one type of protection or a combination of two or more, in which case it is a combined type; where a product does not match a listed name but has the same function, it is classified according to its function. Any adjustment to the scope arising from changes in laws, product standards, technology or industrial policy is governed by announcements and decisions of the certification authority.
