Note(s)

  1. In this subclass, in the absence of an indication to the contrary, an ingredient is classified in the last appropriate place. [2]
  2. In this subclass:
  3. In this subclass, it is desirable to add, in conformity with paragraph 83 of the Guide, after the double oblique stroke, the indexing codes representing additional information which relates to individual constituents of a technical subject which is already classified as such. This additional information concerns the indication of the essential ingredients of a mixture. The indexing codes have the same numbers as the classification symbols but a colon is used instead of the oblique stroke. These indexing codes should be presented as linked to the classification symbols with which they are associated, in conformity with paragraph 85 (a) of the Guide. [2]
