DEFINITION

Classification: 508/115

With naturally occurring resin, salt thereof, agar, natural rubber, tar, pitch, animal glue, turpentine, or carbohydrate gum:

(under subclass 113) Compositions which contain, in addition to the graphite, coal or elemental carbon, at least one of carbohydrate gum, turpentine, animal glue, pitch, tar, natural rubber, agar, naturally occurring resins, or salts of naturally occurring resins.

(1) Note. For the definition of naturally occurring resin, see the definition of subclass 200 in Class 530, Chemistry: Natural Resins or Derivatives; Peptides or Proteins: Lignins or Reaction Products Thereof.

(2) Note. Animal glue is intended to encompass the normally impure animal matter of proteinaceous nature which found early use as an adhesive, etc. A substance identified as "glue", without further elucidation, will be construed as animal glue.

(3) Note. Carbohydrate gum is intended to encompass the complex carbohydrate mucilaginous plant stem excretions which normally yield sugar on hydrolysis. Examples are gum arabic and gum tragacanth. A substance identified as gum, without further elucidation, will be construed as carbohydrate gum.

(4) Note. Tar and pitch are generally considered as mineral oils for purposes of classification.
