That article makes the interesting point (which I'll repeat here for those who can't be bothered to read it) that Samsung logistics use the Netherlands as a hub for Europe.
While the ban doesn't stretch across Europe, they would have to change that to get devices into other European countries.
I think that if they don't generate the sales from that hub and only from the subsidiaries on each country then they can still use it...
No, they aren't allowed to import them into the Netherlands at all for any reason so long as the ban is in place.
