25 CFR §243.5

1. (a)Anyone, including non-Natives, may own imported reindeer in Alaska for any legitimate purpose, subject to State and Federal animal health laws and regulations.
2. (b)Imported reindeer must not be intermingled with, or be bred to, Alaskan reindeer without our written consent. Any offspring resulting from a mating with Alaskan reindeer are considered Alaskan reindeer and a non-Native owner may not maintain these reindeer alive in Alaska.
3. (c)This paragraph applies if a non-Native owner of imported reindeer in Alaska contracts with a Native reindeer owner to keep and manage the imported reindeer. The non-Native owner must:
   1. (1)Distinguish the imported reindeer from the Alaskan reindeer by applying a distinctly different permanent earmark or tattoo on all imported reindeer; and
   2. (2)Register the earmark or tattoo with the State Division of Agriculture book of livestock brand marks.
