Duty Info on: Buses, Vans and Radial Tyres?

Hello friends,

I am based in the United Kingdom and thinking of importing a few items to india, I wanted to know more information about this.

1. Buses/Minibuses (USED): What is the duty rate on these? what documents will I need for them to be imported, Also can they be imported at any port such as Kandla, Gujarat? Also after import will there be any restrictions on them?

2. Vans (UK SPEC for transport): What is the duty rate on these? what documents will I need for them to be imported, Also can they be imported at any port such as Kandla, Gujarat? Also after import will there be any restrictions on them?

3. New Radial Truck Tyres: What is the duty rate on these? what documents will I need for them to be imported, Also can they be imported at any port such as Kandla, Gujarat? Also after import will there be any restrictions on them?

If anyone has any information that could help it would be greatly appreciated, I am also looking for contacts that can help with this venture
