Missouri allows retail sale of "permissible items of consumer fireworks" year-round for holders of an annual retailer permit, and during two seasonal windows, June 20 through July 10 and December 20 through January 2, for holders of a seasonal retail permit, under Mo. Rev. Stat. § 320.141. Specifically named devices such as cherry bombs and M-80s stay banned statewide, and a violation involving them is a felony.
Jurisdiction scope: This article addresses Missouri's state fireworks law under Mo. Rev. Stat. §§ 320.106 to 320.161: the annual-versus-seasonal retail permit structure, the permissible-fireworks device category and the banned ground-salute list, discharge-proximity restrictions, age rules, local-option authority, and the penalty structure. It does not address a specific city, town, village, or county ordinance beyond the statute's local-option provision.
What Missouri Allows: Permissible Consumer Fireworks
Missouri's statute builds the legal category around federal compliance. It bars a seller from offering anything that falls short of it:
"No wholesaler, annual retailer, or seasonal retailer, or any other person shall sell, offer for sale, store, display, or have in their possession any consumer fireworks that do not comply with the construction, chemical composition, labeling, and other regulations relative to consumer fireworks regulations promulgated by the United States Consumer Product Safety Commission and permitted for use by the general public pursuant to such commission's regulations."
Mo. Rev. Stat. § 320.131(2)
"Permissible items of consumer fireworks," the term § 320.141 uses for what can be sold, is Missouri's label for the federal 1.4G consumer category defined at § 320.106 and built from those CPSC-based construction, composition, and labeling requirements. Matches, toy pistols, toy canes, toy guns, party poppers, and similar devices using low-composition paper caps are excluded from regulation under this chapter entirely, under § 320.131(4).
Banned Devices: Named Ground Salutes Are a Felony
Missouri does not stop at the general consumer-fireworks category. It separately names and bans a specific list of devices:
"Ground salutes commonly known as 'cherry bombs', 'M-80's', 'M-100's', 'M-1000's', and any other tubular salutes or any items described as prohibited chemical components or forbidden devices as listed in the American Pyrotechnics Association Standard 87-1 or which exceed the limits set for consumer fireworks, display fireworks, or proximate fireworks for explosive composition are expressly prohibited from shipment into, manufacture, possession, sale, or use within the state of Missouri for consumer use. Possession, sale, manufacture, or transport of this type of illegal explosive shall be punished as provided by the provisions of section 571.020."
Mo. Rev. Stat. § 320.136
Section 571.020, Missouri's explosive-weapon statute, classifies that kind of offense as a class D felony, which matches § 320.161's own statement that a § 320.136 violation is a felony rather than the chapter's default misdemeanor.
Two Retail License Tracks: Annual vs. Seasonal
Missouri gives retailers a choice of license class rather than fixing one statewide selling calendar:
"Permissible items of consumer fireworks defined in section 320.131 may be sold at wholesale or retail by holders of an annual retailer permit to nonpermitted buyers during a calendar year from the first day of January until the thirty-first day of December. Permissible items of consumer fireworks defined in section 320.131 may be sold at retail by holders of a seasonal retail permit during the selling periods of the twentieth day of June through the tenth day of July and the twentieth day of December through the second day of January."
Mo. Rev. Stat. § 320.141
A retailer holding an annual permit can sell every day of the year. A retailer holding only a seasonal permit is limited to those two windows. A shopper walking into a Missouri fireworks stand outside the holiday season is buying from an annual-permit retailer, not evidence that the seasonal restriction doesn't exist.
Where Fireworks Cannot Be Discharged
Missouri does not set a statewide discharge-date restriction beyond the sale windows above, but it sets several proximity restrictions on where consumer fireworks may be ignited:
"It is unlawful to explode or ignite consumer fireworks within six hundred feet of any church, hospital, mental health facility, school, or within one hundred feet of any location where fireworks are stored, sold, or offered for sale. No person shall ignite or discharge any permissible articles of consumer fireworks within or throw the same from a motorized vehicle including watercraft or any other means of transportation, except where display permit has been issued for a floating vessel or floating platform, nor shall any person place or throw any ignited article of fireworks into or at a motorized vehicle including watercraft or any other means of transportation, or at or near any person or group of people. No person shall ignite or discharge consumer fireworks within three hundred feet of any permanent storage of ignitable liquid, gases, gasoline pump, gasoline filling station, or any nonpermanent structure where fireworks are stored, sold or offered for sale."
Mo. Rev. Stat. § 320.151, subdivisions 3-5
Permit holders may still demonstrate or test fireworks with the local fire service's or the state fire marshal's approval.
Age Rules
Missouri sets separate age floors for buying and for selling. On the purchase side:
"It is unlawful to attempt to sell or to sell at retail any fireworks to children under the age of fourteen years except when such child is in the presence of a parent or guardian."
Mo. Rev. Stat. § 320.151
On the selling side, the same section bars anyone under 16 from selling fireworks or working at a location where they are stored or sold, unless an adult supervises. Separately, Missouri's criminal code makes a criminally negligent sale to a child under 14, without the child's custodial parent's written consent, a distinct offense:
"With criminal negligence sells blasting caps, bulk gunpowder, or explosives to a child under the age of seventeen, or fireworks as defined in section 320.106, to a child under the age of fourteen, unless the child's custodial parent or guardian has consented in writing to the transaction. Criminal negligence as to the age of the child is not an element of this crime."
Mo. Rev. Stat. § 568.070.1(3)
That offense, unlawful transactions with a child, is a class B misdemeanor under § 568.070.2.
Local Option
Cities, towns, and villages, and any county operating under a charter form of government, keep full authority to regulate or prohibit fireworks within their own limits:
"The provisions of sections 320.106 to 320.161 shall not be construed to abrogate or in any way affect the powers of the following political subdivisions to regulate or prohibit fireworks within its corporate limits: (1) Any city, town, or village in this state; or (2) Any county operating under a charter form of government."
Mo. Rev. Stat. § 320.121
The same section makes it unlawful for a manufacturer, distributor, wholesaler, or retailer to sell or ship fireworks by common carrier into a jurisdiction that prohibits them. A first-class charter county with a population over 900,000, meaning St. Louis County, gets a supremacy clause under § 320.122: its own fireworks regulations or prohibitions supersede a conflicting municipal rule within its boundaries, but only to the extent the county's rule is more restrictive than the municipality's. A stricter city ordinance inside St. Louis County still controls.
Permits
No one may manufacture, sell, offer for sale, or ship fireworks into or within Missouri without the applicable state fire marshal permit, a manufacturer, distributor, wholesaler, annual retailer, or seasonal retailer permit, under § 320.111. No permit issues to anyone under 18, permits run the calendar year (except seasonal permits) and are not transferable, and a distributor permit specifically covers bringing display fireworks or articles pyrotechnic into Missouri for resale under § 320.126. Outdoor display and proximate-audience display permits are separately available to municipalities, fair associations, amusement parks, organizations, or individuals, subject to state fire marshal approval and local fire-service inspection, with an exemption for private displays under § 320.127. The state fire marshal can refuse to reissue a permit for up to three years after a false application statement, and can bar a person whose permit was revoked over § 320.136 ground-salute violations from a new permit for up to three years under § 320.116. Every seller must allow the state fire marshal to inspect any location where fireworks are stored, kept, or sold, under § 320.147.
Operating without the required permit is a class A misdemeanor under § 320.161, the same as most other violations of this chapter. It also draws a separate, cumulative civil penalty:
"In addition to any other penalty, any person who manufactures, sells, offers for sale, ships or causes to be shipped into or caused to be shipped into the state of Missouri, for use in Missouri, any items of fireworks without first having the required applicable permit shall be assessed a civil penalty of up to a one thousand dollar fine for each day of operation up to a maximum of ten thousand dollars."
Mo. Rev. Stat. § 320.111
Penalties
Missouri's general penalty provision sets the default and the felony carve-out together:
"Any person violating any provision of sections 320.106 to 320.161 is guilty of a class A misdemeanor, except that a person violating section 320.136 is guilty of a class D felony."
Mo. Rev. Stat. § 320.161
The class A misdemeanor and class D felony fine and imprisonment ranges follow Missouri's general criminal sentencing code rather than being restated in this chapter. The statute does not add an enhanced tier for a second or subsequent violation.
Exemptions
Section 320.156 keeps several activities outside the chapter entirely: railroad and other public or private transportation signals, photographic illumination devices, military and naval forces, peace officers, blank cartridges used for ceremonial, theatrical, or athletic events, and fireworks transported, sold, or used solely for agricultural purposes, so long as the items sold for that purpose are otherwise legal for retail sale and use in Missouri.
Federal Law
Federal law sets the floor: 16 CFR 1500.17 and Part 1507 define which consumer devices may be sold at all; 27 CFR 555.141(a)(7) exempts the importation, distribution and storage of consumer fireworks from ATF licensing (manufacture is not exempt); 18 U.S.C. 836 makes it a federal offense, punishable by up to one year, to transport fireworks into any state whose law specifically prohibits or regulates their use, in violation of that law, except in the course of continuous interstate transportation, with exceptions for common carriers, water carriers and federal agencies; and USPS Publication 52 § 341.22 bars fireworks from the mail entirely.
Missouri's own permit and sale-window system is fairly permissive for permissible consumer fireworks, but the § 320.136 ground-salute ban and any local prohibition can still make possession of a device bought elsewhere a state offense, separate from the federal transport offense that applies whenever a device is used in a state whose own law restricts that use.

Frequently Asked Questions
Are fireworks legal in Missouri?
Permissible items of consumer fireworks, Missouri's term for the federal 1.4G category, are legal from a state-permitted seller under Mo. Rev. Stat. § 320.131. Specifically named devices, including cherry bombs and M-80s, stay banned statewide under § 320.136.
When can you buy fireworks in Missouri?
It depends on the retailer's permit class. An annual-permit retailer can sell permissible consumer fireworks year-round. A seasonal-permit retailer is limited to June 20 through July 10 and December 20 through January 2, under Mo. Rev. Stat. § 320.141.
Is there an age minimum to buy fireworks in Missouri?
Retail sale to a child under 14 is unlawful unless a parent or guardian is present, under Mo. Rev. Stat. § 320.151. A criminally negligent sale to a child under 14 without the custodial parent's or guardian's written consent is a separate offense, unlawful transactions with a child, under § 568.070.
Are cherry bombs or M-80s legal in Missouri?
No. Cherry bombs, M-80s, M-100s, M-1000s, other tubular salutes, and any device exceeding consumer, display, or proximate fireworks composition limits are expressly banned, and possessing, selling, manufacturing, or transporting one is a class D felony under Mo. Rev. Stat. § 320.136 and § 320.161.
Where can't you set off fireworks in Missouri?
Not within 600 feet of a church, hospital, mental health facility, or school; not within 100 feet of anywhere fireworks are stored or sold; not within 300 feet of stored ignitable liquid, gas, or a gas station; and not from or into a motor vehicle or watercraft, except under a permitted floating display, under Mo. Rev. Stat. § 320.151.
Can Missouri cities or counties ban fireworks even though state law allows them?
Yes. Cities, towns, villages, and any charter-form county may regulate or prohibit fireworks within their own limits under Mo. Rev. Stat. § 320.121, and a seller cannot ship or sell into a jurisdiction that prohibits them. St. Louis County's rules take precedence over conflicting municipal rules within it under § 320.122, but only where the county's rule is more restrictive than the municipality's; a stricter city ordinance still controls.
What is the penalty for illegal fireworks in Missouri?
A general violation of Missouri's fireworks chapter, including operating without the required permit, is a class A misdemeanor. A violation involving the banned ground-salute devices in § 320.136 is a class D felony instead, under Mo. Rev. Stat. § 320.161. Selling or shipping fireworks without the required state permit also draws a separate, additional civil penalty of up to $1,000 per day, capped at $10,000, under § 320.111.
