Factory act or BMC - electronic assembly work with small unit of 6 workers?

I am having a small unit with 6 workers and using 3hp of power in drill machine and mini grinder.
We do electronic assembly work. do we come under factory act of BMC. kindly help.

You do not come under Factory Act but you would fall under Shop & Establishment Act

What is being carried on in the unit with 6 workers is a manufacturing process. Therefore, in my opinion, it would not come under the purview of the Shops and Establishments Act. However, check whether such units are notified as factories u/s 85(1) of the Factories Act,1948 in your State.
