Based on the amount of investment by an investor in Tamil Nadu, we have categorised the companies into 2 segments: Large Industries and MSMEs

MSME
Enterprises with investment in Plant and Machinery or Equipment is not more than Rs.125 crores and Annual Turnover is not more than Rs. 500 crores

Single window response for necessary clearances has been very good. They co-ordinated, represented and facilitated for faster approvals for starting and operating. We appreciate their timely intervention for speeding up the necessary approvals. We hope they continue the good work and get better in the coming years. The priority for prompt replies and urgent action was very evident which has made coordination with departments very easy and efficient.
