Service tax for anodizing work

Hello,

I am starting new business for Aluminium Sections & Engineering Parts Anodizing, can anybody guide me if service tax is liable for this type of works?

Business in Brief:

We will do anodizing on Job Work basis, we will not purchase or sell any material , we will be doing only anodizing as job work.

Please advise me if service tax is liable if yes under which section and what is tax percentage.

Thanks in advance,
