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 should, as far as possible, be 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 should be restricted to: [4]
      1. aspects which are characteristic for the production of a particular article, and not classifiable in subclass B29B or C; [4]
      2. combined operations for making the particular article which are not fully classifiable in subclass B29C[4]
  4. The codes of subclass B29K are only for use as indexing codes associated with subclasses B29B, B29C, or D so as to provide information concerning the materials used. [4]
  5. The codes of subclass B29L are only for use as indexing codes associated with subclass B29C, so as to provide information concerning the articles produced by the techniques classified in subclass B29C[4]
