raw materials are purchasing from SEZ units under AA without payment of Duty. other than RM we are purchasing of payment of duty. so, accumulative of ITC we are dispatching of export under AA with payment of IGST for refund. is it applicable under rule 96(10)? or accumulative of ITC can we get refund under rule 89 4a 4b
