SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS

The line between this Class (87) and Class 428, Stock Material or Miscellaneous Articles, is that any plural layer product or stock material which includes a component classifiable in this Class (87) will be placed in this Class; a plural layer stock material or product in general with no structure of the Class 87 type will be classified in Class 428, Stock Material or Miscellaneous Articles. See also reference to Class 87 in the main definition of Class 428, Lines With Other Classes, Intermediate Articles, and subclass 592 for metallic stock material having a helical component.
