Let laptop from Iraq to Germany send to my brother for repair so that I can't get any problems with the border toll, is that possible?
So if that is not exactly super sensitive or important data on it, I would save all the effort.
I would risk too big that he gets stuck somewhere.
Best at customs specify the laptop, customs clearance. Generate the shipment as insured and best by airmail. Although expensive, there are fewer places where there can be problems. On normal shipping I would not do that because the area is too uncertain. It would be better if you then leave the laptop directly at the airport if there's a post office. So you minimize that he can already be stolen inland. He is covered by the insurance and such things are always treated by the freighter Senisbel. One generally wants to avoid generating an insured event.
Why do you want to bring him first to Iraq? You are in Germany.
Since he wants to move but also to Holland and to Spain, at the moment he wants to build a house and waits for the life insurance of the mother who still lives ect.ect. He lives in his own world.
