We are merchant exporters dealing in various products.As per current procedure, we purchase goods from a particular factory against CT1/ARE1 so that no excise is levied on us. After goods are exported, we provide proof of export and Form H (for sales tax exemption) to the concerned factory. How would GST impact us and what will be the process now?

Taxable event in the GST regime is supply of goods.
Exports being inter-State supply, you would be required to
obtain GST registration. The manufacturer would be supplying
you the goods on the payment of IGST or CGST and SGST/
UTGST as applicable. You may avail of input stage credit of the
tax paid on goods and services and export the goods under
bond/LUT. Unutilized credit can be availed as refund. Alternatively,
you may export the goods on payment of integrated
tax and refund of integrated tax would be available to you.
