S.C. Code Ann. § 36-2-105

(1) "Goods" means all things (including specially manufactured goods) which are movable at the time of identification to the contract for sale other than the money in which the price is to be paid, investment securities (Title 36, Chapter 8) and things in action. "Goods" also includes the unborn young of animals and growing crops and other identified things attached to realty as described in the section on goods to be severed from realty (SECTION 36-2-107). (2) Goods must be both existing and identified before any interest in them can pass. Goods which are not both existing and identified are "future" goods. A purported present sale of future goods or of any interest therein operates as a contract to sell. (3) There may be a sale of a part interest in existing identified goods. (4) An undivided share in an identified bulk of fungible goods is sufficiently identified to be sold although the quantity of the bulk is not determined. Any agreed proportion of such a bulk or any quantity thereof agreed upon by number, weight or other measure may to the extent of the seller's interest in the bulk be sold to the buyer who then becomes an owner in common. (5) "Lot" means a parcel or a single article which is the subject matter of a separate sale or delivery, whether or not it is sufficient to perform the contract. (6) "Commercial unit" means such a unit of goods as by commercial usage is a single whole for purposes of sale and division of which materially impairs its character or value on the market or in use. A commercial unit may be a single article (as a machine) or a set of articles (as a suite of furniture or an assortment of sizes) or a quantity (as a bale, gross, or carload) or any other unit treated in use or in the relevant market as a single whole. SECTION 36-2-106. Definitions: "contract"; "agreement"; "contract for sale"; "sale"; "present sale"; "conforming to contract"; "termination"; "cancellation". (1) In this chapter unless the context otherwise requires "contract" and "agreement" are limited to those relating to the present or future sale of goods. "Contract for sale" includes both a present sale of goods and a contract to sell goods at a future time. A "sale" consists in the passing of title from the seller to the buyer for a price (SECTION 36-2-401). A "present sale" means a sale which is accomplished by the making of the contract. (2) Goods or conduct including any part of a performance are"conforming" or conform to the contract when they are in accordance with the obligations under the contract. (3) "Termination" occurs when either party pursuant to a power created by agreement or law puts an end to the contract otherwise than for its breach. On "termination" all obligations which are still executory on both sides are discharged but any right based on prior breach or performance survives. (4) "Cancellation" occurs when either party puts an end to the contract for breach by the other and its effect is the same as that of "termination" except that the canceling party also retains any remedy for breach of the whole contract or any unperformed balance.
