Assessee is in business of ocean freight, when he booked consignment on behalf of clients for exports, he pay ocean freight from his pocket and charge ocean freight from client with some Mark up...so my question is as per notification issued on 25.01.2018 ocean freight is exempt so will my input service and out put service is exempt or do i need to pay gst on my markup?
