Non-Electric Shock Tube Igniter
A non-electric igniter employing shock tubing to transmit a detonation signal to explosive charges in construction blasting. It uses a low-energy signal for safe initiation, fitting HTS 3603.50.00.00 for igniters distinct from detonators.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If includes detonating cord assembly
Igniters bundled with detonating cords are classified under detonating cords subheading.
If purely electronic without pyrotechnic charge
Non-explosive electronic igniters resemble switches and fall under electrical apparatus in Chapter 85.
