How can one apply to get an ESI exemption in Mumbai?

As regards exemption from ESI though there is a provision to exempt it (Section 87 of the ESI Act 1948) provided that the employees are otherwise in receipt of substantially similar or superior benefits than is provided in the Act, for a period of one year at a time, so it is virtually impossible to provide matching facilities like medical coverage to employee and family, sickness benefit etc. The other option is to enhance salary levels to all the employees above the ceiling limit, presently Rs. 21,000/- pm.

But it seems you can get a PF exemption? https://www.epfindia.gov.in/site_doc...f?id=sm1_index
So why not ESIC?

In PF it is possible by creating a registered PF Trust with matching benefits, it is not a very difficult task. For ESI one has to be in a position to match the benefits in house. Pl go through the ESI benefits then it can be understood how difficult, cumbersome and costly it is to maintain such facilities.
