Trade in elephant ivory is one of the things that's on the no-fly list. It's also on the no ship by air/boat/train list.
It's something called The Lacey Act, which was passed over a hundred years ago.

From Wikipedia;
The Lacey Act protects both plants and wildlife by creating civil and criminal penalties for a wide array of violations. It prohibits trade in wildlife, fish, and plants that have been illegally taken, transported or sold. The law is still in effect, although it has been amended several times.
