SITCSection 5
U.S. imports of safety fuses, detonating fuses, percussion caps, ignitors & electric detonators (SITC 59320) totaled $23.8M in April 2026, traded with 24 countries.
Importers of Safety Fuses, Detonating Fuses, Percussion Caps, Ignitors & Electric Detonators paid $1.1M in duties in April 2026 — an effective duty rate of 11% on $10.3M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataInitiating and transmission devices — safety fuses, detonating cord (detonating fuses), percussion caps, ignitors, and electric detonators — are the functional links between a power source and a main explosive charge, making their reliability specifications critical to mining, construction, and demolition safety. Each device type has distinct sensitivity, delay-time, and energy-output characteristics that determine suitability for a given blasting application. ATF licensing requirements apply to importers, and DOT hazard class assignments differ across device types (e.g., detonating cord vs. electric detonators carry different compatibility group designations), requiring careful documentation at entry.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Yes. Detonators, caps, and other initiating devices are classified as explosive materials under the Safe Explosives Act, and importers must hold an ATF federal explosives importer's license. Each device type may also carry a distinct DOT hazard classification and compatibility group, which affects how they can be co-loaded with other hazardous materials during transport.
A safety fuse burns at a slow, controlled rate to provide a time delay between ignition and detonation of a blasting cap — it does not itself detonate. Detonating cord (detonating fuse) contains a core of high explosive and propagates a detonation wave at very high velocity, used to simultaneously initiate multiple charges or transmit detonation over distance. The two are not interchangeable, and specifying the wrong type is a serious safety risk.
