DTDC Courier & Cargo — custom clearance charges

Address:

Gurgaon, Haryana, 122001

Hi, i have selected dtdc to courier my old clothes, kitchen utensils, toys from australia to india. Total weight is 80kg and cost i paid aud 684 for door to door delivery. Shipment has been reached to igi airport at delhi and dtdc india is asking me 8000 inr + gst + any other charges for custom clearance over the phone call. And the person called me is not ready to give the split how this 8k charges comes.

I am not sure for the used clothes and utensils this much of custom i should pay. Also dtdc is asking me to come to airport for this process.
