Dear Prashant,
My apologies for stating it as Corporation rather than Contribution.
Here are a few facts on ESI ACT, 1948:
The Act was originally applicable to non-seasonal factories using power and employing 20 or more persons; but it is now applicable to non-seasonal power-using factories employing 10 or more persons and non-power-using factories employing 20 or more persons.
Under Section 1(5) of the Act, the Scheme has been extended to shops, hotels, restaurants, cinemas including preview theatres, road motor transport undertakings, and newspaper establishments employing 20 or more persons.
The existing wage limit for coverage under the Act is Rs. 10,000 per month (with effect from 1.10.2006).
AREAS COVERED
The ESI Scheme is being implemented area-wise by stages. The Scheme has already been implemented in different areas in the following States/Union Territories:
STATES
All the States except Nagaland, Manipur, Tripura, Sikkim, Arunachal Pradesh, and Mizoram.
UNION TERRITORIES

Trust it clarifies.
