Additional Item Names Added to Valid EX Approval
Effective April 2, 2015 PHMSA will no longer process additional item/name requests for fireworks EX Approval applications. A change to the product name has no bearing on the safety / classification of the firework, the original classification of the firework, or regulatory compliance. It is required by PHMSA and found in the 2018 APA 87-1A, B, and C, standards, to mark the EX or FC number on the firework device or packaging if the device is to small. For further information please see the Federal Register Notice (Notice No. 15-10) published April 2, 2015 (80 FR 17706).
