you will need to visit the DHL office or post office get the imei number from the package and seal the package again, sign it, then you will have to obtain 2 letters one from post office and one from customs, fill the form on PTA website and send the documents by post/TCS to PTA then they will send you a msg when ur NOC is ready and will send you by post... wait for the NOC, when it arrives, take it to the post office and give it.. next day they will handover the parcel after you pay the custom duty...
