Gst on reimbursement of cha bills

Hi,

my question is weather GST is applicable on reimbursements made by our CHA Agents if no is there any liability arises on payments made against the reimbursements which included Transport Charges or Crane Charges paid by our CHA on our behalf in that case weather RCM Liability lies with my company.

for example our clearing agent has raised bill of reimbusement withour GST which included payments made for Transportation to URD dealer, Crane Charges to URD dealer & Airline Charges (Registered Dealer). so in that case our clearing agent has made payments to URD Dealers weather in that case is it our liability under RCM Provisions of GST.
