A colleague of mine ordered a Steinway grand piano from Hamburg with an ivory keyboard (legally made in Germany). He went through a long process of trying to get it into the US (including a few phone calls to the Secretary of the Interior), but there's an absolute ban on importing ivory to the US. In the end, he had to get a plastic keyboard made for the piano before it could be shipped here; the original ivory keyboard is in a closet in his mother's house in Berlin.
