DEFINITION

Classification: 524/9

Cellular material derived from plant or animal source DNRM other than cotton, farinaceous meals or flours, blood, diatomaceous earth, chalk, or other fossilized matter:

(under subclass 1) Subject matter wherein a solid polymer or specified intermediate condensation product is admixed with a designated nonreactant naturally occurring material or chemically modified naturally occurring material and wherein the natural or modified material still retains a certain amount of the original tissue structure of the animal or plant.

(1) Note. Included within the term are materials which are chopped, cut, comminuted, pulverized, milled, sliced, etc. Included herein is soybean and wood flour.

(2) Note. An extract is considered to be devoid of original cellular structure.

(3) Note. Although cotton, whole blood, farinaceous meals and flours, and diatomaceous earth or chalk may have cellular structure they have been specifically excluded from this subclass and are to be found in other subclasses in this schedule.

(4) Note. In the absence of information to the contrary a protein is presumed to be devoid of cellular structure unless indicated otherwise.

(5) Note. In the absence of information to the contrary a cellulose or cellulose derivative is considered to be devoid of cellular structure.
