Overview

All explosives must be in compliance with 49 CFR Hazardous Materials Regulations (HMR). Division 1.3G Display Fireworks, Division 1.4G Consumer Fireworks and Articles Pyrotechnics 1.4G may be classed and approved by the Associate Administrator without prior examination and offered for transportation if the fireworks meets the requirements in §173.64, which requires a firework device be manufactured in accordance with the American Pyrotechnic Association (APA) Standard 87-1, IBR as part of the HMR. The Approvals and Permits Division, within PHMSA's Office of Hazardous Materials Safety processes the applications and if approved, a formal Classification of Explosives letter is issued on behalf of the Associate Administrator signifying the new explosive is approved for transportation and assigned an "EX Number".

PHMSA revised the HMR applicable to the approval of Division 1.4G consumer fireworks UN0336 and established DOT-approved fireworks certification agencies (FCA) that provide an alternative to the approval process for Division 1.4G consumer fireworks. Now manufacturers of Division 1.4G consumer fireworks have the option of applying to a DOT-approved FCA instead of applying to PHMSA. The FCA will notify the manufacturer, in writing if the fireworks have been certified, classed and assigned an FC number or if the application is denied (see 49 CFR § 173.65). For additional information on the FCA program follow the links that have been provided in the webpage.
