What does firework grade mean?

Firework grades follow China's mandatory standard GB 10631-2025 'Safety and Quality of Fireworks', classifying fireworks into Grades A, B, C, and D based on pyrotechnic composition, blast power, danger level, and operator qualifications. Danger decreases from A to D. Simple distinction: Grades A & B are for professional use only; public purchase is prohibited. Grades C & D are for personal use and legally available for home purchase.
