The CPSC sets performance and labeling standards for consumer fireworks, and CBP enforces those standards at the border. Display fireworks — those not intended for consumer use — may additionally require ATF import permits. DOT hazmat regulations govern transport of all pyrotechnic articles.

Signalling flares, fog signals, and similar functional pyrotechnic devices are classified under subheading 360490 rather than with consumer fireworks (360410). The distinction rests on intended use: articles designed for safety signalling or meteorological purposes fall in 360490, while articles designed for entertainment are in 360410.
