Explosives and their components are manufactured at explosives plants (engineering works for military-use products). The manufacture on site of bulk extraction explosives is a more modern method of manufacture. Military explosives are transferred from the manufacturer directly into the possession of the armed forces. CE-marked explosives are evaluated by the manufacturer or a notified body depending on applicable module.

Most fireworks are manufactured in China. Firework types are tested by a testing body in accordance with national practice.

Manufacturers are responsible for the conformity of fireworks and explosives. The manufacturer is an individual or organisation in charge of the design, manufacture, testing and inspection (submission for inspection) of an explosive.
