§12A-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 (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.
