Last updated: August 2026 dataDetonating caps — also called blasting caps or detonators in non-electric form — are the primary initiating device for high-explosive charges in mining, construction, and demolition. Entered under 3603400000, they require an ATF federal explosives import permit and must meet DOT hazmat transport standards. Mexico and Spain lead US imports under this heading, with Germany also a significant source, reflecting both geographic proximity and established European explosives industry expertise.

Detonating caps (3603400000) are initiated by a burning safety fuse or detonating cord rather than an electrical signal, while electric detonators (3603600000) fire via an electric current through a bridge wire. This functional difference determines the HTS subheading and also affects ATF licensing categories and DOT transport classifications.
Imports of detonating caps originating in Mexico may qualify for preferential tariff treatment under USMCA, provided the goods meet the applicable rules-of-origin requirements. Importers should verify origin documentation carefully, as explosives supply chains can involve components sourced from multiple countries. Consult a licensed customs broker to confirm eligibility.
