You need to pay tax. Have a look at this link https://cleartax.in/s/place-of-supply-of-goods  you can get a solution to your issue.

Whether your Recipient is in Within India? If so and If the recipient is registered under gst, in that case the place of supply shall be fixed under Sec.12(8) of IGST Act. And according to this section the POS shall be the location of the registered recipient and accordingly cgst, sgst or igst shall have to be levied.

 

If the Recipient's place is outside India, in that case the POS shall be fixed U/s 13, where it says that POS will be the destination of goods, hence not taxable.

Sorry, If the Recipient's place is outside India, in that case the POS shall be fixed U/s 13, where it says that POS will be the destination of goods, hence it is to be treated as Inter-state supply, hence IGST shall be levied. If it satisfies the conditions to become export service then only it shall be treated as zero rated supply and benefit of ZRS can be obtained.

As per the proviso inserted in Amendment Act 32 of 2018 , & the same was effective by Notification 1/2019 IGST Act
