is there any way to know how much customs charge if applied to my parcel before the delivery of
my parcel,according to tracking-my parcel cleared the customs in two days..and sent for local
post office now.can it be checked online,contacts etc with reference to parcel track number,thanks

well there no way until you receive it. If you want more info then you can mail the particular custom centre.  but i would suggest you to do that.  better wait for the parcel.  If your parcel is cleared without any notification then there are chances that no duty has been levied.  but that's not sure. hope for the best.

if for another 15 days it still say's "waiting for customs inspection" then u might wanna call the customs and provide your tracking number, they are most likely to give u an indian post tracking number or tell u to call them and u can get help from customs after that...
