Vat on milk products

Hello

We have a dairy farm and we are going to produce curd, ghee, buttermilk, badam milk and khoa.

We are doing proper pouching. I wanted to know what rules of VAT apply in the state of Karnataka on milk products.

If we are procuring milk from outside at some rate, then what would be the amount on which VAT will be applicable?

Please let me know.

Thanks

Nikhil
