Laws regarding the sale, storage, and use of fireworks vary from state to state, but it is often illegal to:

• advertise to sell or transfer fireworks without a license or permit to do so, or with an expired license to do so;

• advertise that you are in the fireworks business without a license or permit to do so;

• sell or deliver fireworks to minors, or to persons under the age permitted by law (16 years of age, for example, and 18 years of age for dangerous fireworks);

• buy fireworks if you are under the legal age (16 years of age, for example, and 18 years of age for dangerous fireworks);

• sell fireworks anywhere other than a fixed, licensed place of business;

• sell, give, or transfer special effects fireworks to a person who does not have a pyrotechnic license;

• sell or offer to sell fireworks outside of permitted time periods—such as June and July, December and January;

• store fireworks once your license has expired, been revoked, or is surrendered;

• allow a fire nuisance (anything that causes or tends to cause an increase of fire danger) to exist in a place where fireworks are sold, manufactured, assembled, packaged, stored, or distributed;

• fail to record a license number on fireworks sales or shipments;

• use special effects fireworks (manufactured, designed, assembled, or used in connection with television, movies, or theater) without a pyrotechnic license.

• discharge fireworks within city limits without a license or permit;

• give, deliver, or sell dangerous fireworks to someone without a permit;

• discharge fireworks where they are likely to harm another person, or with the intent to cause chaos, fear or panic;

• possess or discharge agricultural or wildlife fireworks without a permit (fireworks devices designed to prevent crop damage or unwanted animals, and distributed to farmers, ranchers, and growers through a wildlife management program administered by the United States Department of the Interior or an equivalent state or local governmental agency).

• discharge fireworks from a public roadway, public property, park, lake or U.S. Army Corps of Engineers property;

• sell, use, or discharge an emergency signaling device (a flare) that has not been registered with the state fire marshal;

• use an emergency signaling device (a flare) in an unintended manner;

• discharge fireworks on property you do not own without written permission from the property owner;

• discharge fireworks in violation of a local, county, or statewide burn ban.

In addition to state laws located in state statutes (often in the health and safety code, occupations code, or penal or criminal code), cities and counties often have ordinances and regulations that restrict the possession, sale, and discharge of fireworks. Violations of fireworks laws may be prosecuted as a misdemeanor or as a felony, and sometimes include jail time for possession of large amounts of dangerous fireworks, for example.

In North Carolina, the sale, storage, and use of fireworks are regulated by both state statutes and local ordinances. It is illegal to sell or transfer fireworks without the appropriate license or permit, or to operate a fireworks business without proper licensing. North Carolina law prohibits the sale of fireworks to minors and restricts the types of fireworks that can be sold to the general public, limiting sales to a specific subset of less powerful fireworks. The sale of more powerful 'dangerous fireworks' is generally restricted to licensed professionals. It is also illegal to sell fireworks outside of licensed premises or during non-permitted times. Storage of fireworks must comply with safety regulations, and it is illegal to store them if a license has expired or been revoked. Fireworks cannot be discharged within city limits without a permit, near certain buildings like churches or hospitals, or in proximity to flammable substances. The use of bottle rockets and similar devices is prohibited. Public displays of fireworks require a permit, and it is illegal to discharge fireworks on property without the owner's written permission or in violation of any local burn bans. Violations of these laws can result in misdemeanor or felony charges, with potential penalties including fines and jail time. Local governments in North Carolina may have additional regulations regarding fireworks, so it is important to check with local authorities for any specific restrictions in a given area.
