Dear Mr.Singh,
If your manufacturing unit is located at Kolkata, you have to follow the minimum wages as per Zone-A of West Bengal for your nature of industry and at different skill. Moreover, other than Basic & DA , there is an state enactment "WB House Rent Allowance Act" where 5% of Basic & DA should be HRA.
CTC has no legal status. It depends on organization decision and remuneration structure. Other than what Praveen B has mentioned, there may be some more items which may be considered as CTC - e.g. Gratuity, Subsidise Canteen, Transport provided if any by organization etc. etc. For any further clarification, you may contact me if you think so.
Thanks & Regds.,
S K Bandyopadhyay(West Bengal)
