there are some individual people selling sometimes (worth to PM K0SH as he might help),
but it depends on availability,
I usually bring from Germany some supplies to my brother who lives in Riyadh,
its allowed to bring with from EU for personal use, or asking some friends to bring supplies from EU,
I recently found a new site in Kuwait, the site says they sell within Kuwait but for out side Kuwait they asked to
to contact them,
Home
it seems the only online shop in that part of the world, so try to contact them, and try a small order,
and as Kuwait is within Gulf region, I guess that the custom wont be very strict,
Good luck and let us know how it goes with the site in Kuwait,
