Eligibility:

Composition Scheme Check:

1. For manufacturers (except notified goods), restaurant service and supplier of goods (1.5 Crore)
2. If providing services, other than restaurant services, then check marginal threshold
3. If out of above two, then check whether eligible for concessional rate notification

basically person who are not eligible for the Composition Scheme u/s 10 

then he may opt for the N/N 2 / 2019 

Roughly speaking then it is for service providers .
