TYPES OF COMMERCIAL FIREWORKS AND THEIR STORAGE
In general, there are three main types of commercial fireworks. These three categories of devices are closely regulated by several government agencies, with special focus on the the Department of Alcohol, Tobacco, and Firearms.
Display fireworks are the large and grandiose type of displays usually utilized in professional fireworks displays. These shows are closely supervised by a trained pyrotechnician. This type of firework produces a visible and / or audible effect in the form of combustion, deflagration, or deterioration. This includes all fireworks falling under the following distinctions;
Containing more than 2 grains (130 mg.) of flash powder
- Aerial shells containing more than 40 g. of pyrotechnic compositions
- Display pieces which exceed the limits of explosive materials classified as “consumer fireworks
- Fused set pieces containing components which together exceed 50 mg, of flash powder
These fireworks are all classified under the Department of Transportation under UN0333, UN0334, and UN0335, and must be transported under the guidlines set aside for fireworks.
To be in possession of such fireworks, one must have procured an ATF Federal Explosives License in compliance with 27 CFR, Part 555.
Commercial fireworks are the standard type of fireworks one will find readily available in stores and roadside stands. These fireworks are small, and commercially available to the general public. These include;
- Ground devices containing 50 mg. or less of flash powder
- Aerial devices containing 130 mg. or less of flash powder.
While commercial fireworks are not regulated by the ATF, they are still classified by the Department of Transportation as products UN0336 and UN0337, and any person manufacturing consumer fireworks for commercial use MUST obtain a Federal Explosives Manufacturing License.
These particular devices are pyrotechnic devices manufactured for professional use. They are similar to commercial fireworks in chemical composition and construction, but are not intended for consumer use. These devices also fall under the regulation of 27 CFR 555.11.
