Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported in bulk without specified detonating function
Unspecified fuses may default to percussion caps or igniters in other 3603 subheadings.
If for twine or rope made of synthetic fibers without explosives
Textile coverings alone are classified as ropes under Chapter 56.
If containing flash powder for signal or pyrotechnic use
Pyrotechnic cords shift to heading 3604 for signaling devices.

Import Tips & Compliance
• Include manufacturer's test reports confirming detonation velocity over 6,000 m/s
• Coordinate with CBP for pre-clearance due to high scrutiny on explosive imports
• Package in wooden barrels or spools per DOT regulations to prevent friction ignition

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.
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.
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.
