Taxation on dropshipping to India from China

[Mani8]

Hi Members,

I am running a new store where I have sold a product from China to India (my supplier is based out of China and customer was in India). While fulfilling order, I am being asked for Tax ID. Can someone pls suggest what all requirements do I need to fulfill from taxation standpoint in order to make this through.

Also would be helpful to know that for this particular case, whose Tax ID is needed? The customer who ordered the product or mine (Store owning company)?

PS: I am using CJ Dropshipping.

Thanks.
