Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

3603Same rate: 20.5%

If classified as other safety fuses

Lower explosive speed fuses are safety fuses under 3603.00, not high-velocity detonating cords.

8544.42.90Higher: 37.6% vs 20.5%

If for insulated electrical conductors used in non-detonating applications

If the cord lacks explosive core and functions only as wiring, it falls under Chapter 85 for insulated cables.

3926.90.99Higher: 22.8% vs 20.5%

If for plastic tubing without embedded explosives

Empty flexible plastic sheaths are other plastic articles under Chapter 39.
