Procedure for sale of imported goods in domestic market

Hi,

I would like to know the process and procedure for sale of imported goods in the domestic market. I am basically looking out for the following

1. goods imported into India and sold to a registred dealer in India  - who can take the credit of receoverbale taxes and how?

2. goods imported into India and sold to a trader  in India - who can take the credit of receoverbale taxes and how?

3.  goods imported into India and sold outside India(sale benig not high sea sales)  - what taxes are applicable and how to handle the recoverable taxes during import.

4. goods imported into India by a trader and exported (sale benig not high sea sales) - what taxes are applicable and what is to be done with the recoverable taxes at the time of import.

I have checked the excise and customs manuals give on the cbec site, i could not find them.

thanks in advance.
