Every consumer firework sold in the United States has to carry a warning label, and federal law spells out almost exactly what that label must say. The fireworks warning label requirements come from the U.S. Consumer Product Safety Commission (CPSC) under the Federal Hazardous Substances Act (FHSA), with the specific cautionary language for each device type set out in 16 CFR 1500.14(b)(7). A firework whose label is missing, incomplete, or wrong for the device is treated as a “misbranded hazardous substance” and cannot legally be shipped or sold across state lines.1Consumer Product Safety Commission. Fireworks Business Guidance
The Core Elements Every Label Must Carry
The FHSA sets a baseline that applies to every consumer firework, regardless of device type. Every device or package must display:
- The name and place of business of the manufacturer, packer, distributor, or seller.
- A signal word: either “WARNING” or “CAUTION.” “DANGER” is reserved for substances classified as extremely flammable, corrosive, or highly toxic and does not apply to standard consumer fireworks.
- A hazard statement describing the principal hazard, such as “Flammable” or “Emits Showers of Sparks.”
- Precautionary measures telling users what to do or avoid.
- Storage and handling instructions where special care is needed.
All of this must appear in English, in conspicuous and legible type that contrasts with the rest of the label.2Office of the Law Revision Counsel. 15 USC 1261 – Definitions
A handful of instructions repeat across almost every device category. “Use only under adult supervision” appears on every consumer firework (manufacturers may optionally add “close” before “adult supervision”). “For outdoor use only” is required on every device, with no exceptions in the federal rule. “Light fuse and get away” appears on most device types; the exceptions are devices designed to be held, like handle fountains and sparklers, where getting away isn’t possible. “Do not hold in hand” appears on Roman candles, spike fountains, rockets, and wheels.
One thing the federal rule does not require is a specific safe distance in feet. The mandated phrase is “get away,” not “stay 25 feet back” or any other number. If you see a specific distance on a package, that came from the manufacturer or a state rule, not the federal regulation.
What Each Type of Firework Must Say
Federal regulation prescribes the exact cautionary language for each category of consumer firework. The wording changes because the hazards and safe handling change with the device.3eCFR. 16 CFR 1500.14 – Products Requiring Special Labeling Under Federal Hazardous Substances Act
Fountains
Fountain labels carry “WARNING” or “CAUTION” followed by “FLAMMABLE” (or “EMITS SHOWERS OF SPARKS” if that better describes the device). The instructions must state: use only under adult supervision, for outdoor use only, place on a level surface, and light fuse and get away.
Roman Candles
Roman candle labels state “WARNING” or “CAUTION” followed by “SHOOTS FLAMING BALLS.” Required instructions: use only under adult supervision, for outdoor use only, stick the butt end in the ground, do not hold in hand, and light fuse and get away.
Rockets With Sticks
Stick rockets must be labeled “WARNING” or “CAUTION” followed by “FLAMMABLE.” Users must be told to place the rocket in a wooden trough or iron pipe at a 75-degree angle pointing away from people or flammable material, not to hold it in hand, and to light the fuse and get away.
Sparklers
Sparklers have a unique layout. The front and back panels must both display “WARNING” or “CAUTION” followed by “FLAMMABLE.” A separate panel must carry additional cautionary text: use only under adult supervision, for outdoor use only, do not touch the glowing wire, hold in hand with arm extended away from the body, and keep the burning end or sparks away from clothing or other flammable material.
Wheels and Ground Spinners
Wheel devices must be labeled “WARNING” or “CAUTION” followed by “FLAMMABLE” or “EMITS SHOWERS OF SPARKS.” Users must be told to attach the device securely with a nail through the hole (or, for ground spinners, place it on a hard flat surface), then light the fuse and get away.
Other Device Types
The regulation also prescribes specific label text for California candles, spike and handle fountains, and illuminating torches. Each follows the same structure: signal word, hazard statement, adult supervision, outdoor-use-only, and device-specific handling. Handle fountains and illuminating torches are among the few devices where holding in hand is permitted, and their labels must instruct users to point the device away from the body.
Type Size, Ratio, and Contrast
Printing the right words isn’t enough. Federal regulation sets minimum type sizes based on the area of the label’s principal display panel, and the minimums scale with package size. On a panel of two square inches or less, the signal word must be at least 3/64 of an inch tall. On a panel larger than 30 square inches, the signal word must be at least 5/32 of an inch. The ratio of letter height to width cannot exceed three to one, which stops manufacturers from using extremely narrow fonts that hit the height requirement but stay hard to read.4eCFR. 16 CFR 1500.121 – Labeling Requirements; Prominence, Placement, and Conspicuousness
Contrast matters too. Cautionary text must appear in sharp contrast against its background. Dark text on a dark background fails the standard even when the type size is correct, and fireworks packaging is often heavily illustrated, so this is a requirement regulators actually check.
Assortment Packages
Pre-packaged assortments get a partial labeling exemption on two conditions. First, every individual firework inside must carry its own complete label. Second, the outer package must display a specific warning: “WARNING—This assortment contains items that may be hazardous if misused and should be used only under adult supervision. IMPORTANT—Read cautions on individual items carefully.” That statement must appear within a bordered rectangle and meet the same type-size standards as individual device labels.5eCFR. 16 CFR 1500.83 – Exemptions From Full Labeling and Banned Hazardous Substances Requirements
The exemption covers only the outer packaging. Open an assortment, find an unlabeled or incompletely labeled device inside, and that device is misbranded no matter what the box says.
Labeling Cannot Legalize a Banned Device
A perfectly labeled firework can still be illegal if it belongs to a banned category. Some devices are prohibited outright and cannot be sold to consumers regardless of the label. The key federal thresholds:
- Firecrackers with more than 50 milligrams of pyrotechnic composition are banned, which covers M-80s, cherry bombs, silver salutes, quarter-sticks, and similar large firecrackers.6eCFR. 16 CFR 1500.17 – Banned Hazardous Substances
- Fireworks producing audible effects with more than 2 grains (130 milligrams) of pyrotechnic composition are banned, covering larger aerial salutes.7Consumer Product Safety Commission. Fireworks FAQ
- Devices resembling candy or food, such as “dragon eggs” and “cracker balls,” are banned because children may mistake them for something edible.
- Reloadable tube aerial shells larger than 1.75 inches in outer diameter are banned.
- Any firework that fails to comply with the Part 1507 construction standards is treated as a banned hazardous substance, even if it stays within the composition limits above.
The only exception is narrow: devices distributed to farmers and ranchers through a federal or state wildlife management program, in response to a written application, and only when other control methods are unavailable.
Penalties for Missing or Incorrect Labels
A consumer firework with an incorrect or missing label is a “misbranded hazardous substance” under the FHSA. Introducing a misbranded or banned hazardous substance into interstate commerce is prohibited under 15 U.S.C. 1263, as is altering or removing a required label after shipment. Receiving a misbranded firework in interstate commerce and then offering it for sale is independently prohibited.8GovInfo. 15 USC 1263 – Prohibited Acts
The CPSC works with U.S. Customs to intercept non-compliant shipments at ports of entry, and the agency has seized hundreds of millions of banned fireworks devices over the years.9Consumer Product Safety Commission. CPSC Announces Indictments in Multistate Fireworks Investigation Violations can result in civil penalties, criminal prosecution, product seizures, and mandatory recalls. State laws add another layer of permit systems and category bans on top of the federal framework, so a federally compliant label does not guarantee a product is legal to sell in a given state.
