DEFINITION

Classification: 508/114

With silk, sponge, hair, skin, leather, meat, or fibrous plant matter (e.g., cork, bamboo, bark, sawdust, cotton, etc.):

(under subclass 113) Compositions which contain, in addition to the graphite, coal, or elemental carbon, at least one of fibrous plant matter, meat, leather, skin, hair, sponge or silk.

(1) Note. Meat is intended to indicate the flesh of animals.

(2) Note. Sponge is intended to encompass natural sponge, or synthetic sponge which is identified as sponge rather than as a particular chemical substance. If a component is identified both as sponge and in terms of its chemical structure, said component should be classified as an original here and should be cross-referenced to the appropriate chemical structure subclass.

(3) Note. Hair is intended to encompass the fine, threadlike outgrowths from the skin of an animal; skin is intended to encompass the outer covering or integument of an animal body.

(4) Note. Fibrous plant matter indicates plant matter in which the plant fibers have not been destroyed.

(5) Note. Chemically modified cellulose (e.g. CMC, cellulose ethers, etc.) is not considered as fibrous plant matter.
