The dual-use nature of explosive precursor chemicals (EPCs) makes implementing counter-improvised explosive device (C-IED) measures complicated. These chemicals are misused to manufacture improvised explosives and their diversion poses a significant challenge to national and international efforts aimed at preventing the proliferation of IEDs. Many EPCs, however, are critical components in industrial, commercial, and agricultural work, and restrictions—if not considerate of stakeholders in legitimate supply chains—risk negatively impacting key industries.

In Regulating Explosive Precursor Chemicals—the latest Small Arms Survey podcast—Manon Blancafort and Paul Amoroso discuss how effective EPC regulation requires constant vigilance, periodic review and when necessary, updating of threat lists, persistent clear communication, stakeholder engagement, and international collaboration.
