Basically, the requirements, while based on the IEC publications (CISPR22 & IEC 60950, as well as ITU Recommendations) BUT, vary from province to province and are to a large extent dependent on whether you have a customer for the product in China who wants to expend political capital on getting the device approved.
You need a Chinese national in China to champion it for you, and you will to a large extent be dependent on his/her political connections. There is no simple answer. Ciao, Vic
