Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If marketed as full detonator with delay
Devices with primary explosive and long delays may classify as electric detonators.
If pyrotechnic signal-only without explosive charge
Flash or signal devices without detonating capability fall under fireworks heading.
