OCTROI is charge that are levied for taking one item/goods from one state to another state. Usually if you buy something online, there will be a clause which says "OCTROI charges if any will be paid by the consignee".
I heard that in Mumbai you still need to pay OCTROI
Some of the states in India that don't collect OCTROI are
Andhra Pradesh
Karnataka
Delhi
Tamil Nadu
West Bengal
Gujrat (abolished in 2008)
Punjab(abolished 2006)
I donno the complete list of states. But to know the state specific information you can visit that particular state's tax department website.
