When is CCC mark required?

[dougplc]

I am designing electrical machine controls for a pair of industrial machines that will be installed in a factory in China.

I have searched the Web and found a couple of sites that describe the CCC mark but it is unclear if my machine controls need to have components with a CCC mark.

It seems like the mark is only required if we were trying to sell individual components. Can anyone provide further info?

Are there other electrical specs that are required in China?

Thanks.
