Definition

Common questions

Why is commercial pyrotechnic powder attractive to bomb-makers compared to military or industrial explosives?+

Fireworks are legally purchasable by consumers in many jurisdictions without the licensing or background checks required for military or industrial explosives, so extracting powder from fireworks avoids the access controls that restrict other explosive materials.

What changed in regulatory attention after the Boston Marathon bombing regarding this material?+

The bombing prompted discussion of reporting requirements around fireworks and pyrotechnic product composition, aimed at making bulk or suspicious purchases and the underlying chemical composition more traceable, though regulatory approaches vary by jurisdiction.
