Gun law in the United States is defined by a number of state and federal statutes.  Sale or delivery of firearms is restricted in South Carolina like any other U.S. state.  In almost all the states of the U.S., an importer, manufacturer, dealer or collector shall be licensed under the Federal Gun Control Act of 1968, to be a lawful seller.

According to the South Carolina laws, a resident who may lawfully purchase and receive delivery of a rifle or shotgun in South Carolina may purchase a rifle or shotgun in a contiguous state from a federal firearms licensee (FFL), by meeting all federal requirements.

The law prohibits knowingly buying, selling, transporting, pawning, receiving, or possessing a stolen handgun or a gun from which the original serial number has been removed or obliterated.  Selling, renting or giving away or participating in sale, renting, giving away, or disposing of a machine gun or firearm commonly known as a machine gun, military firearm, sawed-off shotgun, or sawed-off rifle in any other way is unlawful in the state of South Carolina.

An alien unlawfully present in the United States is prohibited from selling a firearm in the state[i].  Such an alien is liable for a fine of not more than ten thousand dollars or imprisonment for not more than ten years, or both.

It is unlawful for a person to knowingly sell, offer to sell, deliver, lease, rent, barter, exchange, or transport for sale into South Carolina a firearm to a person knowing that such person is not lawfully present in the United States[ii].  Upon conviction, such a person shall be fined not more than two thousand dollars or imprisoned for not more than three years, or both.
