I’ve taken this off a site about scrimshaw. I’ve gotten into that
Regulated by U.S. Fish and Wildlife Service under the 1972 Marine
Mammal Protection Act. Raw walrus ivory predating the Dec. 21, 1972
law, tusks bearing the Alaska state walrus ivory registration tags or
post-law walrus ivory that has been carved or scrimshawed by an
Alaskan native (Eskimo) are legal to buy, possess, and sell.
Raw walrus ivory obtained after 12/21/72 is not legal to buy or sell
unless both parties are Eskimo (it is legal to own). A $30 export
permit is required to ship walrus ivory or oosik (legal as per above)
out of the United States.
FOSSIL WALRUS IVORY-
Not restricted as it pre-dates the 1972 cutoff, it is legal to buy
and sell anywhere within the United States. Shipping ivory or oosik
(fossil walrus penal bone) out of the U. S. requires a $30 permit.
