is a mixture of 5% 325-mesh titanium sponge and 5% 200-mesh zirconium hydride (with another patent document listing 5% zirconium hydroxide). The oxidizer is a mixture of 85% 200-mesh ammonium nitrate and 15% ammonium perchlorate. The patents on these formulations were applied for on August 20, 2001. United States law As Tannerite is supplied as components, not themselves explosive, combining the components to constitute an explosive is regulated by laws on manufacturing explosives. In the United States, the Bureau of Alcohol, Tobacco, Firearms and Explosives advises: "Persons manufacturing explosives for their own personal, non-business use only (e.g., personal target practice) are not required to have a Federal explosives license or permit." However, "persons falling into certain categories are prohibited from possessing explosive materials". Those prohibited from possessing explosives include most non-citizens, unlawful drug users and addicts, those convicted or indicted for serious crimes, fugitives, and those who have been officially declared mentally defective or have been committed to a mental institution. There are also restrictions at state and local level. For example, in California a permit may be required to use or possess Tannerite. Various regulations also govern the storage of unmixed explosives. As oxidizers and combustibles, there are some restrictions in the United States on shipping of the unmixed components. Notable incidents A Minnesota man was fined $2,583 and sentenced to three years' probation on charges of detonating an explosive device and unlawful possession of components for explosives after he detonated of Tannerite inside the bed of a dump truck by shooting it with a rifle chambered in .50 BMG from away on January 14, 2008, in Red Wing, Minnesota. The man was on probation when he mixed and shot the Tannerite and was not allowed to possess firearms or explosives. A 20-year-old man in Busti, New York, shot of Tannerite on January 13, 2013, that sent a particularly "loud boom" through much of southern Chautauqua County, New York, and extending as far south as Pennsylvania, at least away. Multiple other sounds of explosions were also reported in the incident. The explosive noise caused numerous phone calls to the Chautauqua County Sheriff's Office, the New York State Police, and other law enforcement in the area. The September 2016 New York and New Jersey bombings involved improvised explosive devices that contained "a compound similar to a commercial explosive known as Tannerite", set off by a small charge of unstable hexamethylene
