Explosives for lawful target practice must be used once mixed: any transport, storage or commercial use of mixed explosives falls under federal explosives laws,[3] and cannot be transported in mixed form without following strict regulations including insurance, packaging, signage on the transport vehicle, storage magazines, etc.
As oxidizers and combustibles, the unmixed components still have some shipping restrictions in the United States.
[4][5] A Maryland law intended specifically to ban the sale or ownership of consumer products containing binary explosive components (such as Tannerite brand rifle targets) became effective on October 1, 2012, and expanded the definition of an explosive to include, in addition to "bombs and destructive devices designed to operate by chemical, mechanical, or explosive action", "two or more components that are advertised and sold together with instructions on how to combine the components to create an explosive".
This region includes national forests and grasslands in the states of Colorado, Wyoming, Kansas, Nebraska, and South Dakota.
[8] In New York State, a 2020 law included binary explosives, including Tannerite, in the definition of "explosives" that require a permit for their purchase, ownership, possession, transportation, or use within the state.
