Missouri Fireworks

Missouri sets no statewide dates or hours for using fireworks; any city, town or village, and any charter county, may regulate or prohibit them within its limits (RSMo 320.121). Seasonal retailers may sell only June 20–July 10 and December 20–January 2, while permitted annual retailers may sell year-round (RSMo 320.106).

Missouri's fire marshal rule makes it unlawful to sell or attempt to sell any fireworks to a child under 14 unless the child is with a parent or guardian, and no one under 16 may sell fireworks or work where they are stored or sold unless supervised by someone at least 18 (11 CSR 40-3.010). Seasonal retailers may sell consumer fireworks only during the fireworks season — June 20 to July 10 and December 20 to January 2 — while permitted annual retailers may sell all year (RSMo 320.106). Toy caps, party poppers and similar items with 0.25 grain of explosive or less may be sold and used at any time (320.131).

In Missouri, consumers need no personal permit to buy consumer fireworks. Sellers need a state fire marshal permit (RSMo 320.111); seasonal retailers sell June 20–July 10 and December 20–January 2, and annual retailers year-round (320.106). Cities, towns, villages and charter counties may regulate or ban fireworks locally (320.121).
