incase anybody else is interested here is some info that i found:
fedex should be able to clear it from the customs in pakistan. as far as the charges go:
-no custom duty but there will be a ~20% tax charge (do not remember what kind of tax the fedex guy in pak said it was) which you or the recipient can pay.
-also for a 8lbs package fedex will charge about $170.
-also it will be good to have insurance
