Section 2--105. 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).

(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.
