Safety fuses are explosive initiating devices regulated by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), which requires importers to hold a valid federal explosives import permit. Shipments must also comply with DOT hazardous materials packaging and labeling standards. Consult a licensed customs broker experienced in explosives imports before attempting entry.
Safety fuses (3603100000) burn at a slow, controlled rate to provide a time delay before initiating a detonator or charge, while detonating cords (3603200000) transmit a detonation wave at high velocity and are used to simultaneously initiate multiple charges. The distinction is critical for both HTS classification and ATF licensing categories.
