Why do you need FIRCs? Does your single invoice exceed USD 20000/-? If not, then continue business as usual.
If your single invoice exceed USD 20,000/- (which is extremely unlikely), then you need to ship the item with all the customs formalities. Please consult a Clearing and Forwarding agent for this and they will guide you how to proceed.
