(1) Note. See the definition of subclass 615, below, for an explanation of the term "composite".
(2) Note. While a loose mass of particles, each of which comprises a particular metal or alloy, coated with a different particular metal or alloy, is considered to be a stock-material* for this class and subclass, a consolidated mass of such particles or a mixture of such particles with other particles is considered to be a composition, and is classified in a composition class. See, in particular, the definition of Class 75, subclass 251.
