For the past few weeks I have observed that Islamabad International Mail Office has decided that duty will be charged on all the parcel coming from AliExpress.
My most recent experience is that I get a iPhone case, I think it was $6 or 7... i was charged Rs341 as taxes... the duty amount was Rs. 16.... and rest were all kind of fuzool taxes/charges... the best part was the receipt say, packet opening and repacking charges (it was never opened or repacked).
And I just checked, yet another parcel of mine has gone to customs... guess it is time to say goodbye to AliExpress.
