Okla. Stat. tit. 12A, § 12A-2-105

"Lot"; "Commercial unit".

Definitions: Transferability; "Goods"; "Future" Goods; "Lot";

"Commercial Unit".

(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 (Article 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 2-107) but does

not include information.

(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.
