It might also be that paperwork is delayed on the other side. If a lot of bureaucracy is involved shipping to non-EU countries in a way that the recipients wouldn't have to pay tax twice and customs on top, paperwork can take time. IMHO it also makes sense to collect the shipments for the non-EU countries and send them all together, to not have the same bureaucracy procedures over and over again. Even Nokia had trouble sending devices to some countries.
