There are three classes of explosive materials. These classes, together with the description of explosive materials comprising each class, are as follows:

High explosives

Explosive materials which can be caused to detonate by means of a blasting cap when unconfined, (for example, dynamite, flash powders, and bulk salutes).

Low explosives

Explosive materials which can be caused to deflagrate when confined (for example, black powder, safety fuses, igniters, igniter cords, fuse lighters, and “display fireworks” classified as UN0333, UN0334, or UN0335 by the U.S. Department of Transportation regulations at 49 CFR 172.101, except for bulk salutes).

Blasting agents.

(For example, ammonium nitrate-fuel oil and certain water-gels)
