WORKING OF PLASTICS; WORKING OF SUBSTANCES IN A PLASTIC STATE IN GENERAL (processing doughs A21C; working chocolate A23G; casting of metals B22; working cement, clay B28; chemical aspects, see section C, particularly C08; working glass C03B; candle making C11C 5/00; making soap C11D 13/00; manufacture of artificial filaments, threads, fibres, bristles or ribbons D01D, D01F; manufacture of articles from cellulosic fibrous suspensions or from papier-mâche D21J)
 B29

Note(s)

  1. 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 B31[4]
  2. In this class, the following term is used with the meaning indicated:
    • "plastics" means macromolecular compounds or compositions based on such compounds.
  3. In this class, the following rules apply:
    1. The working of plastics is, as far as possible, classified primarily according to the particular shaping technique used, e.g. in subclass B29C[4]
    2. A product is not classified in this class unless it results from a technique which is covered by this class.
    3. Classification according to production of particular articles in subclass B29D is restricted to:
      1. aspects which are characteristic for the production of a particular article, and not classifiable in subclass B29B or B29C;
      2. combined operations for making the particular article which are not fully classifiable in subclass B29C[4]
