I will need to set up a new corporation. No India presence.
Trying to get free advice about starting an international pharmaceutical company probably isn't the best way to go, man.
That's your biggest red tape.
Hi. I may be able to help you. Please let me know a little more about your business plan.
You should start with understanding the 'Pulse Polio Initiative' that the Government of India(GoI) runs. GoI is a critical player in any plans you'll have for entering the Indian market. The 'red tape' will depend on the type of Polio vaccine you intend to introduce - IPV/OPV. There are many Indian manufacturers of polio vaccines and they will be your competition as well as sources of red tape. Until recently, there were no IPV manufacturers, but now the Serum Institute is a significant player in the IPV space, locally and globally.
