i know it is forbidden to trade it here in the netherlands because is it an ingredient in the manufacturing process of xtc.
this might be valid for other countries too, but i don't know. it might give a problem at customs when you buy it from outside the european union. i was very glad to be able to get some from another perfumer here in holland. she gave me all she had.
i'm sorry to not have an answer to your question. i don't think it would be impossible to get some, though.
