@Nrupal
your definitions cover a wide range, please be specific of HSN codes used for GST registration, also mention that 1) is manufacture or contract job provider
Regarding 2) the correct HSN would be available under GST input invoice,

Sir, we do not need the code for GST it's need for PF & ESIC registration.
1st company is contract job and 2nd is private limited.
Please guide for Primary Business Activity for both.
Regards,
Nrupal

NIC code is product base, and such broad description can not find anything , there are classifications of all products, though GSTN / HSN codes are different, but with those, it would be easy to find out the exact code

viz for electricals, there are almost 20 sections, in manufacture plus service, which one is appropriate, one can not decide on such wide explanation, better if they can provide at least one major product GSTN/HSN code then it would be easy to find out the exact NIC code

viz cable blowing does not means that it is electrical cable, it can be telephone, or automobile cable also, it can be LT cable ( below 1000 watt) , HT cable ( above 1000 watt) or railway cable (separate entity in NIC)

however for esic, "establishment run with electricity"

if you are registering on behalf on somebody else then ask them to sit with you and search here for proper NIC, because once allotted, it can not be changed or amended
