Dear Nimitt,
As per my knowledge GIDC(Antalia) area come in Navsari district and GIDC come in non - implemented areas in Surat(Gujrat) as per ESI scheme, however ESI is not applicable to GIDC area.
ESI Salary limit is Rs. 15000/- excluding Washing Allowance.
Kindly find attached list of non - implemented areas in ESI scheme.
Regards
Shyam
