Query

Yes, it will be covered under Zero rated supply and ITC accumulated for making such supply can be claimed as refund via RFD01. But, supply internationally must be a supply under bond/LUT for availing this refund.

As per Section 16 IGST Act : yes it will be treated as zero rated supply , as it's Exempted Goods hence No IGST is leviable on Export And As per proviso in Section 54 CGST Act : Provided that no refund of unutilised input tax credit shall be allowed in cases other than--
[i] zero rated supplies made without payment of tax;

Hence can claim Refund by filing RFD 01A

Sorry for above reply : As it's zero rated sale But As per sub section (2) of Section 16 IGST Act : Subject to the provisions of sub-section [5] of section 17 of the Central Goods and Services Tax Act, credit of input tax may be availed for making zero-rated supplies, notwithstanding that such supply may be an exempt supply. So you can claim ITC for unutised Credit But can't claim Refund . Note : As per Sub Rule (4) of Rule 89 , The refund can be claim on Unutilised credit as accordance to Section 16 IGST Act . So you cannot claim Refund
