3603.50.00.00 - Igniters

Category 3603.50.00.00 specifically covers "Igniters." This classification applies to devices designed to initiate or ignite explosive charges, pyrotechnic compositions, or other combustible materials. Igniters function by producing a flame, spark, or hot gas.

Unlike its sibling categories, which cover fuses for delayed ignition (3603.10), detonating cords for propagating explosions (3603.20), and initiating devices like percussion caps and detonating caps (3603.30 and 3603.40), igniters are the primary source of ignition. While electric detonators (3603.60) also initiate explosions, they do so through an electrical current, whereas igniters can be initiated by various means, including friction, heat, or direct flame. The key differentiator for igniters is their role as the initial spark or flame source for a larger explosive or pyrotechnic event.

As a leaf node, this category has no further subcategories. Classification within 3603.50.00.00 is determined by the item's primary function as an igniter, irrespective of specific initiating mechanism (unless it qualifies as an electric detonator) or the type of material it is intended to ignite, provided that material falls within the scope of Chapter 36.
