ATF says you can have up to 50 pounds of black powder explosive in your possession at once. All tannerite is, is ammonium nitrate and aluminum flake.
Here's a wiki for it: http://en.wikipedia.org/wiki/Tannerite

I believe it is not an explosive until mixed and then is regulated. If you're approaching 50 pounds give me a call and I'll help you get rid of it. It really does take a high power round. Last time I tried it a 7.62x39 went right through the middle without setting it off. I gathered it back up and taped the jar shut and a 7.62x54R round did it.
