3603.60.00.00 - Electric detonators

This HTS category, 3603.60.00.00, specifically encompasses electric detonators. These are devices designed to initiate an explosive charge through the passage of an electric current, typically via a heating element or bridging wire. They are crucial components in controlled blasting operations across various industries, including mining, construction, and demolition.

Electric detonators are distinguished from their sibling categories by their mode of initiation. Unlike safety fuses (3603.10), which rely on a burning element, or detonating cords (3603.20), which transmit a shock wave, electric detonators require an external electrical signal to activate. Similarly, they are distinct from percussion caps (3603.30) and detonating caps (3603.40), which are initiated by mechanical impact or shock, and igniters (3603.50), which are designed to produce a flame or spark to ignite other materials.

As this is a leaf node within the HTS, there are no further subdivisions under this code. Classification within 3603.60.00.00 hinges on the product's inherent design and primary function as an electrically activated initiator for explosive charges. Exclusions would typically include accessories solely used for connecting or powering electric detonators, which would be classified elsewhere based on their own function and composition.
