Is it legal to mail a deer tail within the country?

My friends hunt deer (for food, they throw out the pelt, bones, antlers, etc.). I am a practicing taxidermist that wants as little of the animal to go to waste as possible. I have a deer tail I treated years ago that a friend wants, who lives a couple states over.

I tried looking at laws within the states, but couldn't find anything specific to this problem. It's a whitetail buck specifically, though I'm not sure if the sex is important when it's just the tail. Either way, is there anything I should know before I pack it up and mail it?
