Note(s) This class does not cover the working of plastics sheet material in a manner analogous to the working of paper, which is covered by class Fulltext... Hierarchy... Expanded...B31. [4] In this class, the following term is used with the meaning indicated: "plastics" means macromolecular compounds or compositions based on such compounds. In this class, the following rules apply: The working of plastics is, as far as possible, classified primarily according to the particular shaping technique used, e.g. in subclass Fulltext... Hierarchy... Expanded...B29C. [4] A product is not classified in this class unless it results from a technique which is covered by this class. Classification according to production of particular articles in subclass Fulltext... Hierarchy...
