South Carolina mace laws let any adult carry pepper spray or mace for self-defense without a permit, provided the canister holds no more than fifty cubic centimeters of product. That size cap, set by S.C. Code § 16-23-470, is the rule that matters most. Go over it and you’re looking at a misdemeanor punishable by up to three years in prison, a fine of up to $5,000, or both.1South Carolina Legislature. South Carolina Code 16-23-470 – Illegal Possession of Tear-Gas Gun or Ammunition Everything else about carrying mace in the state — where you can take it, when you can use it, what happens if you don’t — flows from that starting point.
The Fifty Cubic Centimeter Rule
The statute begins by banning possession, use, transport, sale, and purchase of tear gas devices outright. Then it carves out a civilian exception for self-defense, limited to canisters or cartridges of fifty cubic centimeters or less.1South Carolina Legislature. South Carolina Code 16-23-470 – Illegal Possession of Tear-Gas Gun or Ammunition That’s roughly 1.7 fluid ounces, smaller than most travel-size toiletries. Compact personal-defense sprays sit comfortably inside that limit. Larger bear-spray canisters and professional-grade units do not.
The penalty for crossing the line is a misdemeanor carrying up to three years in prison, up to $5,000 in fines, or both. The same penalty applies whether you’re carrying an oversized canister, possessing a tear gas device for something other than self-defense, or selling a non-compliant product.
Who Can Carry
Section 16-23-470 sets no minimum age and says nothing about criminal history. That’s a meaningful contrast with South Carolina’s firearms laws, which do bar felons. Because the tear gas statute is silent on prior convictions, a felony record does not automatically prevent someone from carrying a compliant canister the way it blocks handgun possession.
Court orders can change that. Probation conditions, protective orders, or pretrial release terms often restrict anything a judge considers a weapon. If you’re on supervision or have an active case, check your conditions before you carry.
Retailers routinely require buyers to be 18, and manufacturers print their own age warnings. A minor who brings pepper spray to school faces a much more serious problem than any store policy, as explained below.
Where You Can’t Take It
K-12 Schools
South Carolina bans any weapon, device, or object capable of inflicting bodily injury on elementary or secondary school property, and the state Attorney General has concluded that pepper spray qualifies.2South Carolina Attorney General. Opinion Regarding Pepper Spray as a Weapon Under SC Code 16-23-430 The catch-all language in § 16-23-430 reaches “any other type of weapon, device, or object which may be used to inflict bodily injury or death,” and the AG opinion placed defensive sprays squarely inside it.3South Carolina Legislature. South Carolina Code 16-23-430 – Carrying Weapon on School Property
This is a felony. A conviction carries up to five years in prison, a fine of up to $5,000, or both. The only exception is for items kept inside a locked vehicle in a closed glove compartment, console, trunk, or secured container in the luggage compartment.
Colleges, Courthouses, and Government Buildings
The companion statute for college campuses and publicly owned buildings, § 16-23-420, is written around “a firearm of any kind.” It does not include the broad “any other weapon, device, or object” language that the AG applied to pepper spray at K-12 schools. In practice, most colleges and government facilities impose their own bans through administrative rules and posted signage, and courthouse security will confiscate a canister at the door regardless of what the statute itself covers. The safest move is to leave your spray in the car before entering any government building or campus.
Private Property
Businesses and property owners can prohibit weapons on their premises through signs or stated policies. Walking past a “no weapons” sign with mace isn’t a state crime, but you can be asked to leave, and refusing opens the door to a trespassing charge.
When You Can Legally Use It
South Carolina’s Protection of Persons and Property Act gives you a strong self-defense framework. Under § 16-11-440, if you’re not engaged in unlawful activity and are attacked somewhere you have a right to be, you have no duty to retreat. You can meet force with force, “including deadly force,” if you reasonably believe it’s necessary to prevent death, great bodily injury, or a violent crime.4South Carolina Legislature. South Carolina Code 16-11-440 – Presumption of Reasonable Fear of Imminent Peril When Using Deadly Force Against Another Unlawfully Entering Residence, Occupied Vehicle or Place of Business
Pepper spray is nondeadly force, which means the threshold for justified use is lower than what the statute spells out for lethal defense. If you’d be justified pulling a firearm, you’re justified reaching for spray. The working standard: an active, imminent threat of physical harm, and a reasonable person in your shoes would have perceived it the same way.
Two things wreck a self-defense claim fast. You can’t be the initial aggressor. If you started the confrontation, physically or by escalating a verbal fight into something threatening, the right to claim self-defense goes with it. And you have to stop once the threat ends. Continuing to spray someone who is retreating, incapacitated, or on the ground converts a defensive act into an offensive one.
Criminal Consequences of Misuse
Using mace outside a legitimate self-defense situation exposes you to assault and battery charges under § 16-3-600. The degree depends on what happened to the person you sprayed.
- Third degree, a misdemeanor, applies when you caused minor injury or attempted to injure someone. Up to 30 days in jail, a fine of up to $500, or both.
- Second degree, a misdemeanor, covers moderate bodily injury. Up to three years, a fine of up to $2,500, or both.
- First degree, a felony, applies when the act was accomplished by means likely to produce death or great bodily injury, or occurred during a robbery, burglary, or similar crime. Up to ten years.
- Assault and battery of a high and aggravated nature, a felony, applies when great bodily injury resulted or the means used were likely to cause death or great bodily injury. Up to twenty years.5South Carolina Legislature. South Carolina Code 16-3-600 – Assault and Battery
Most unjustified pepper spray incidents land in the second or third degree range. Repeated spraying, targeting a vulnerable person, or combining spray with other violence can push the charge higher. Using mace to rob or intimidate someone is treated like using any other weapon during a crime.
Civil Liability After You Spray
South Carolina’s civil immunity statute, § 16-11-450, is written around justified use of “deadly force.”6South Carolina Legislature. South Carolina Code 16-11-450 – Immunity From Criminal Prosecution and Civil Actions Because pepper spray is classified as nondeadly force, that statute may not shield you automatically. Even if no criminal charges are filed, the person you sprayed can sue for medical expenses, lost wages, and pain and suffering.
Your defense in a civil case tracks your criminal defense: the force was proportional, you weren’t the aggressor, and you stopped when the danger passed. Spraying someone who posed no real physical threat, or continuing after they were subdued, is the kind of disproportionate response that civil juries punish. The fee-shifting provision in § 16-11-450(C), which makes a losing plaintiff pay your attorney’s fees, costs, and lost income, is also written around deadly force, so how it would apply to a pepper spray case depends on how a court reads the statute.
Traveling With Mace
By Air
Pepper spray is prohibited in carry-on luggage. TSA will confiscate it at the checkpoint and will not give it back. In checked baggage, you may pack one container of 4 fluid ounces (118 ml) or smaller, provided it has a safety mechanism to prevent accidental discharge and contains no more than 2 percent by mass of CS or CN tear gas.7Transportation Security Administration. Complete List (Alphabetical)
TSA’s permission doesn’t override your airline. American Airlines, Delta, and JetBlue, among others, prohibit pepper spray in any luggage, checked or carry-on. Check the airline’s restricted items list before you pack.
By Rail or Bus
Amtrak bans tear gas and pressurized canisters in both carry-on and checked baggage, and its prohibited items list is not exhaustive — staff can flag anything they consider similar.8Amtrak. Prohibited Items in Baggage Greyhound and other intercity carriers set their own rules, which vary. Check before boarding.
Keeping a Working Canister
Pepper spray has a shelf life, and an expired canister isn’t much better than an empty one. Most manufacturers rate their products for three to four years from the date of manufacture. The limit has more to do with the pressurized propellant than the chemical irritant; capsaicin itself doesn’t degrade quickly, but the propellant that pushes it out does.
An aging canister declines in a predictable order. The spray range drops first, forcing you uncomfortably close to a target. Then the stream weakens into an unreliable dribble. Eventually the canister fails to discharge at all. Check the expiration date printed on the canister and replace it on schedule. If you can’t remember when you bought it, it’s time for a new one.
