narwhal, like walrus, is illegal to import into the US even though it is not listed in the "thou shalt not" category under CITES regs. The native folks on Hudson Bay harvest a number of narwhals(40-50 from what I have read) every year and sell the tusks. Mermaid Supply from Denmark had some GORGEOUS, poker straight pieces at Gembloux, but alas, it was not to be. The funny part is that most of the EU won't let you work even pre-ban elephant ivory (George Trumper, a old line mens barber and fragrance shop in London, got fined 10,000 pound for making some shaving brush handles from ivory that was over 100 years old....if you alter it in any way, it becomes illegal in the UK) , but you can trade in a lot of new stuff that isn't on the CITES list that is pretty much banned by US laws like the Marine Mammal Act.
