GST on Ex work charges paid by overseas agent

I understand that ex-works charges have been paid in respect of services consumed in India. The agent based abroad has arranged freight and paid for the services like freight. It seems that the shipper has agreed to pay for the freight charges  to such agent. The place of supply is India. Therefore, reverse charge machanism would be applicable since GTA services have been supplied and utilized in the supply chain. The recipient i.e. shipper should pay applicable GST.
