The products and compositions classified in this class (208) are those which consist only of a mineral oil or mixtures of mineral oils. Compositions including, in addition to a mineral oil, some nonmineral oil component are classified in other composition classes, usually upon the basis of the use, property or function of the composition. Class 508, Solid Antifriction Devices, Materials Therefor, Lubricant or Separant Compositions for Moving Solid Surfaces,and Miscellaneous Mineral Oil Compositions, is the residual class for heavy mineral oil compositions not otherwise provided for.

The rules for determining Class placement of the Original Reference (OR) for claimed chemical compositions are set forth in the Class Definition of Class 252 in the section LINES WITH OTHER CLASSES AND WITHING THIS CLASS, subsection COMPOSITION CLASS SUPERIORITY, which includes a hierarchical ORDER OF SUPERITY FOR COMPOSITION CLASSES.
