Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If electrical ignition switches
Basic electrical igniters without pyrotechnic elements classify as ignition apparatus under Chapter 85.
If imported as standalone pyrotechnic devices
Safety fuses and detonators separate from engine assemblies fall under Chapter 36 explosives.
If for laboratory heating equipment
Plasma/arc igniters for non-propulsive lab furnaces classify under lab equipment.
