I need to find out if Sodium Cyanide was banned material, but it would be very stupid thing by the UN if they did not ban it.
Don't know if this is helpful or not. I've been searching for a list of banned items and it includes lots of stuff (including pencil erasers of all things), but this is a link to the UN resolution that describes the import/export mechanism in place for Iraq.

I suppose it's possible some of this stuff is dual use, but not when the military is requesting it!
I doubt it is banned, but it is controlled. There are a fair number of chemical process that use it.
