Thank you all
Actually definition of job work is defined very vaguely in Gst Act.
Even repair work on goods can be considered as Job work, if we strictly go with the definition.
But this may not be the intention of law maker.Law maker failed to include his intention in the definition.
If that is the case there is no need to give separate SAC codes for job work services , Repair and maintenance services, cleaning /washing services,Painting services, Technical testing services on goods etc., which requires some treatment or process on goods belongs to others.
Further as per Gst Act, job work and manufacturing defined separately.
In Scheme of classification of services - Heading 9988 speaks about "Manufacturing services on physical inputs (goods) owned by others"
But in Gst rate notification, 9988 - Words "Manufacturing services" and "Job work services" are used interchangeably.
Main problem in Gst - When Act says some thing Rules say some other thing, When act and rules says some thing Gst website (returns filing) says some other thing.
We wish to cover any "any treatment or process undertaken by a person on goods belonging to another registered person" under Job work service, only if it is not covered under any other specific service category like repairs.
