Montana Fireworks Laws (2026): Sale Windows and Penalties

Montana allows retail sale of "permissible fireworks," its term for the federal consumer-fireworks category, during two windows each year, June 24 through July 5 and December 29 through December 31, under Mont. Code Ann. §§ 50-37-105 and 50-37-106. Violating this chapter, Title 50, chapter 37, is a misdemeanor under § 50-37-110, punishable by a fine of $100 to $500, 30 days to 6 months in county jail, or both, and the chapter separately lets a fire official seize illegal stock at the owner's expense.

Jurisdiction scope: This article addresses Montana's state fireworks law under Mont. Code Ann. §§ 50-37-101 to 50-37-110 and § 7-33-4206: the permissible-fireworks device category, the two statutory sale windows, the location-based use restrictions, the seller-age rule, local-option authority, and the chapter's misdemeanor penalty. It does not address city or town ordinances beyond the local-option statute.

What Montana Allows: Permissible Fireworks

Montana's statute defines its legal category by reference to federal rules rather than listing devices in state code:

"Permissible fireworks include and are limited to those that meet the definition of consumer fireworks as provided in 27 CFR 555.11 and that comply with the construction, chemical composition, and labeling regulations of the U.S. consumer product safety commission, as set forth in 16 CFR, parts 1500 and 1507."

Mont. Code Ann. § 50-37-105

That ties Montana's legal category to the same federal 1.4G consumer-fireworks classification most broad-allow states use. Anything outside that federal definition, including true display-grade fireworks, is not available to individual consumers and instead requires a supervised public display permit.

Sale Window

Retail sale of permissible fireworks is limited to two calendar windows:

"A person, firm, or corporation may offer permissible fireworks, as defined in 50-37-105, of any kind for sale at retail only during the following periods: (1) June 24 through July 5; and (2) December 29 through December 31."

Mont. Code Ann. § 50-37-106

The winter window is short, just three days, and does not carry into January the way it does in most neighboring states. Retail sale outside these windows is unlawful, and § 50-37-103(4) separately bars selling permissible fireworks by mail-order solicitation regardless of the date.

Where Fireworks Cannot Be Sold or Discharged

Montana does not set a statewide discharge-date window beyond the sale windows above, but it sets several location-based restrictions on where permissible fireworks can be sold or set off:

"(5) It is unlawful to sell or offer for sale fireworks as defined in 50-37-101 or permissible fireworks as enumerated in 50-37-105 within 300 feet of a hospital or church. (6) It is unlawful for an individual, firm, partnership, or corporation to discharge or cause to be discharged any pyrotechnics, fireworks as defined in 50-37-101, or permissible fireworks as enumerated in 50-37-105: (a) within the exterior boundaries of a state forest, state park, or state recreation area; (b) within 100 feet of a fireworks retail sales location; (c) from, inside, or toward a motor vehicle; or (d) in the vicinity of another person or group of people or any animal in a manner likely to expose them to the risk of injury."

Mont. Code Ann. § 50-37-103(5)-(6)

Age Rules: Seller, Not Buyer

Montana's age restriction is written around who may sell, not who may buy:

"It is unlawful for an individual under the age of 18 to possess for sale, sell, or offer for sale within the state permissible fireworks enumerated in 50-37-105."

Mont. Code Ann. § 50-37-103(2)

Montana's fireworks chapter sets no statewide age minimum for purchasing permissible fireworks. A wholesaler faces a separate, more specific bar: a fireworks wholesaler permit applicant must furnish proof, under oath, of being at least 18 years old, of good moral character, and never convicted of a crime involving the use, possession, or sale of fireworks, under § 50-37-104(3)(b).

Local Option

City and town councils keep their own authority over fireworks:

"The city or town council has power to regulate or prohibit the building of bonfires or the explosion, use, or selling of fireworks, firecrackers, torpedoes, other pyrotechnics, or toy pistols or guns within the city or town."

Mont. Code Ann. § 7-33-4206

The state fireworks chapter builds that local authority into its own text, too: nothing in the chapter authorizes the sale of fireworks in a city or town that has banned the sale of fireworks under § 7-33-4206, under § 50-37-102(3). A city or town ordinance adopted under § 7-33-4206 can set its own local penalty for a violation within that city or town, in addition to the statewide misdemeanor the fireworks chapter itself imposes under § 50-37-110.

Permits for Displays and Wholesalers

Anyone selling permissible fireworks at retail does not need a separate state license, but a wholesaler does. A fireworks wholesaler permit comes from the Department of Labor and Industry, requires an application fee, and is conditioned on the age, character, and clean-record requirements described above, under § 50-37-104. Retail and display locations must post a "NO SMOKING" sign at least four inches tall where customers are likely to see it.

Fireworks beyond the permissible-fireworks category, meaning true display-grade devices, require a separate supervised public display permit under § 50-37-107. The state fire prevention and investigation section of the Department of Justice, or the governing body of the city, town, or county where the display is held, may grant the permit, but only to a competent, approved operator, on a written application filed at least 15 days ahead of the display date, after confirming the display's location and method will not be hazardous. The permit is not transferable and only authorizes sale, possession, use, and distribution for that specific display. The permit holder must also carry general liability insurance in a reasonable amount the Department of Justice sets by rule, under § 50-37-108.

Exemptions

Section 50-37-102 keeps several activities outside the chapter entirely: sale to a display-permit holder at the permitted display, use by railroads or other transportation agencies for signal or illumination purposes, use in quarrying, blasting, or other industrial work, blank cartridges used for a show, theater, ceremonial or athletic purpose, or by a military or veterans' organization, and toy paper caps containing less than one-quarter grain of explosive composition per cap.

Penalties

This article covers part 1 of Montana's fireworks chapter, Title 50, chapter 37, which runs from § 50-37-101 through § 50-37-110. The last section in that range, § 50-37-110, is titled "Penalties" and applies to the whole chapter, not just part 1:

"Any person, firm, partnership, association, or corporation violating the provisions of this chapter shall be guilty of a misdemeanor and upon conviction shall be punished by a fine of not less than $100 or more than $500 or, in the case of individuals, the members of a partnership, and the responsible officers and agents of an association or corporation, by imprisonment in the county jail for a period of not less than 30 days or more than 6 months or by both such fine and imprisonment."

Mont. Code Ann. § 50-37-110

That is a flat misdemeanor for any violation of the chapter, whether it is selling outside the statutory windows, selling within 300 feet of a hospital or church, discharging in a restricted location, or any other breach of §§ 50-37-101 to 50-37-109. The fine has both a floor and a ceiling, $100 to $500, and the jail term likewise runs 30 days to 6 months for an individual, or for a partnership's members or an association's or corporation's responsible officers and agents. The chapter does not add an enhanced tier for a second or subsequent violation.

Separately from that criminal penalty, the chapter also requires seizure of illegal stock:

"A representative of the state fire prevention and investigation section or any sheriff, police officer, constable, officer of a governmental fire agency organized under Title 7, chapter 33, or firewarden shall seize, take, remove, or cause to be removed at the expense of the owner all stocks of fireworks or combustibles offered or exposed for sale, stored, or held in violation of this chapter."

Mont. Code Ann. § 50-37-109

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.

Montana's own permissible-fireworks category is built directly from the federal 1.4G definition, so a device legal under 16 CFR parts 1500 and 1507 is legal in Montana within the state's sale-window and location rules. Carrying it into a state, or a city or town under § 7-33-4206, whose law prohibits or regulates its use can still trigger the separate federal transport offense.
