DEFINITION

Classification: 106/218

Coating or plastic compositions in the preparation of which a natural resin or derivative, e.g., rosin, copal, gamboge or ester gum, is employed.

(1) Note. For the purpose of this classification, crude products, e.g., pine tar, wood tar, wood pitch, which contain

natural resins or reaction products thereof, are considered to be natural resins. Also included within the scope of natural resins are those compounds of known chemical structure containing the hydrophenanthrene nucleus which are derived from natural resins by treatment of the resin, per se.
