Business in India by a foreign company

Dear Sirs, My name is Karim, I'm the owner of Russian company. I want to: - export fly ash from Indian supplier to customers in Asia; - resell fly ash from Indian supplier to Indian customers. Please give me an advice on how to establish this business. RE: Exporting of fly ash from Indian supplier to customers in Asia 1. Legal jurisdiction. Do I have to setup a subsidiary in India, joint venture with Indian company or setup a branch office in India (setup liaison office in India) OR I can sign contracts with Indian companies just as a Russian company? 2. Licensing. Do I have to get a license to deal with fly ash? If yes, how to get it? How much does it cost? 3. Taxation. Do you recommend to register another offshore company, for example, in BVI, to lower taxes/fees? As I understand I have to receive IEC Code (http://www.dgft.org/iec_code.html) and apply for PAN (http://www.pancardnri.com/)? What taxes should I pay (exact %)? How to do that?
