We are exporters of Spices from Tuticorin Port.
We do exports under LUT
When goods are removed from my go down in Trivandrum to be transported to Tuticorin we generate e invoice and e way bill with the customs rate of exchange.
Once the goods reach Tuticorin the samples are drawn by Spices Board and tested for quality. The will be available within a week..
After this the goods are taken to port for export but at the time of let export the rate of exchange sometimes Changes.
At the time of claiming refund /filing GSTR 1 there is a difference in the e invoice value and the value as shown in Shipping Bill and hence GST system shows error. As there is no provision to amend e invoice we are helpless
Kindly give your suggestions on how to resolve this issue
