N.M. Stat. § 55-2-105
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 [55-2-107 NMSA 1978] ).
(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.
