Consumer fireworks are legal statewide in Missouri and may be discharged on private property in unincorporated Clay County, but Kansas City bans them entirely, county parks prohibit them, and each incorporated city sets its own rules.
Missouri legalized consumer 1.4G fireworks statewide, so aerials, Roman candles, and mortars are lawful to discharge on private property in unincorporated Clay County with the landowner's permission. The county itself imposes no discharge date window on unincorporated land, but it does license seasonal fireworks stands there (about $200 per location through the County Clerk) and prohibits fireworks in all Clay County parks. Cities within the county diverge sharply: Kansas City bans possession and use outright, while Liberty, Gladstone, Kearney, and Smithville each set limited discharge days. Seasonal retailers may sell roughly June 20 through July 10 and December 20 through January 2.
Discharging inside Kansas City or another city that bans fireworks, or in a county park, is a municipal violation with fines; unlicensed stand sales violate county ordinance.
