Supply to self

Dear Sudip

I know X has to take CTP registration in Delhi and also that he needs to deposit tax in advance but that tax which he has deposited in respect of any probable sale (intra-state supply) he may make in Delhi Exhibition which will get adjusted or refunded based on what transpires in Exhibition. 

But what i am asking is whether any tax is payable in respect of inter-state supply of goods from Punjab to Delhi?

Regards
