DEFINITION

Classification: 428/544

(under the class definition) Subject matter drawn to stock-material* or an intermediate-article* which is metallic* or to a shaped metal configuration designed for melting.

(1) Note. The article or stock-material* may also contain nonmetal material when it meets the requirements of this subclass for containing spatially distinct portions of different metals or distinct forms of a metal, contiguous to each other.

(2) Note. Metallic* products made up of a mere random mixture of ingredients, whether or not such ingredients are

structurally defined, are generally considered to be compositions, and are classified in the appropriate composition class (including Class 148 "stock"). However, where the product is characterized by its dimensions, as in subclasses 606+ or by a particular internal structure, due to a particular interrelationship among its elements, or in subclasses 566 and 605 it is considered to be a stock-material*. See the definition of this class.

(3) Note. A manufacture which comprises an indefinite series of articles, whether intermediate or finished, still joined to each other, as their precursor material was joined in the workpiece from which the manufacture was made, is generally considered to be a stock-material* and such manufactures coming within the scope of this mainline subclass are generally found in indented subclasses 571 to 575. See also the class definition of this class (428), section VI, A.
