The address was correct in our database, I don't know why FedEx had a slightly scrambled version.

Any customs issues won't be down to FedEx, it's a domestic issue with Sarajevo customs. FedEx will help monitor the situation, however, and provide advice. We would usually use TNT to ship to an eastern european destination, but as you know they're refusing outright to ship to most Bosnian destinations right now.
