Detaflex Detonating Cord
Detaflex is a low-sensitivity detonating cord with PETN explosive core in a flexible plastic jacket, used in quarrying and demolition. It propagates detonation at 6,400 m/s for reliable blast initiation. Falls under HTS 3603.20.00.00 specifically for detonating cords.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified as other safety fuses
Lower explosive speed fuses are safety fuses under 3603.00, not high-velocity detonating cords.
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.
If for plastic tubing without embedded explosives
Empty flexible plastic sheaths are other plastic articles under Chapter 39.

Import Tips & Compliance
• Declare exact PETN content and velocity specs on commercial invoice for proper HTS verification
• Use refrigerated transport if required by stability data to prevent degradation during shipping
• Avoid common pitfall of mislabeling as safety fuse, which changes classification and duties

Primacord Detonating Cord
Primacord is a high-explosive detonating cord consisting of a core of pentaerythritol tetranitrate (PETN) wrapped in a textile or plastic sheath. It is designed to transmit a detonation wave at high velocity for initiating blasts in mining and construction. Classified under HTS 3603.20.00.00 as a detonating cord used in explosive operations.
Cordtex Detonating Fuse
Cordtex features a PETN-filled core in a woven textile cover, ideal for surface mining and tunneling operations. It ensures precise sequential blasting through shockwave transmission. HTS 3603.20.00.00 covers this as detonating cord distinct from safety fuses.
Shock Tube Detonator Cord
Shock tube cord uses a thin explosive-filled plastic tube to transmit low-energy shock signals to detonators in blasting. Though lower energy than traditional detonating cord, it functions similarly for initiation. Included under HTS 3603.20.00.00 as detonating cord per tariff description.
Rinkord Detonating Cord 25gr/m
Rinkord 25gr/m is a heavy-grade detonating cord with 25 grams per meter PETN loading for deep rock blasting. Its robust construction withstands rough handling in oil and gas extraction. Precisely classified in HTS 3603.20.00.00 for detonating cords.
