Can gst amount be subsumed in my final billing to clients

Dear Sir,

I am in the Freight Forwarding trade where apart from freight there are some other charges like Terminal Handling Charges,B/L charges,X-rays,Carting etc for which there is an element of 18 % GST.

Two questions:

Can I subsume these 18 % in my billing and pay GST so that there is no loss to ex chequer.

Can I bill these charges withour GST to the client.

In short I do not want to charge GST and then cooolect the same and remit after taking set off.

Kindly advise.
