In the case of tannerite, I wonder if the Explosives Branch would approve it for the approved explosives list, and under what conditions?
It and all the other binary explosives in the US were designed to work around the storage and licencing requirements in the US. Farmers and other users could keep ready access to explosives in binary form without the burden of shipping and storage and licencing restrictions. So long as they were used within 24 hours of mixing, all was kosher.
On the surface of it, I suspect with a whole lot of supporting docs the tannerite targets could be approved for use. IIRC, the detonation velocity of these is higher than most commercial detonators, so it's not readily convertable to an illegal use. (Like the booster charge for a U-haul full of ANFO)
