Non-importable means that no CITIES will be issued for that Bear and it is against the law to possess that Bear in the US.

C. United States Marine Mammal Protection Act, 1972.

1.Polar bears are protected under the U.S. Marine Mammal Protection Act (MMPA).

2.The primary objective of the MMPA is to maintain the health and stability of the marine ecosystem and to obtain and maintain an optimum sustainable population of marine mammals.

3.The MMPA prohibits taking and importing marine mammals unless a permit is issued for the purposes of public display, native subsistence, scientific research, or sustaining a depleted species. MMPA revisions in 1994 allow U.S. citizens to import polar bear "trophies" acquired in Canadian hunts. Polar bears in Alaska can be hunted only by Alaskan natives.
