Hierarchy... Expanded...Fulltext... Hierarchy... Expanded...A01N 27/00-A01N 65/00, in the absence of an indication to the contrary, classification is made in the last appropriate place for an active ingredient. [3] - Where a compound is described as existing in tautomeric forms, it is classified as if existing in the form which is classified last in the system. [3]
- Compounds covered by different main groups according to alternatively specified parts of their formulae are classified in every one of the relevant main groups. [3]
- Salts formed between two or more organic compounds are classified as the compound providing the essential ion and it is also classified as the compound providing the other ion. [3]
- Salts or metal chelates of an organic compound are classified as that compound. [3]
- In this subclass, a foodstuff is not considered as an active ingredient. [3]
- Different materials applied in sequence, at different times, are considered as a mixture of all materials employed. [3]
- Synergistic or potentiated compositions are classified as if the synergist or potentiator were an active ingredient. [3]

The indexing codes, which are chosen from the said groups, have the same numbers as the classification symbols, but a colon is used instead of the oblique stroke, and should be linked. [4]Attention is drawn to Chapter IV of the Guide which sets forth the rules concerning the application and presentation of the different types of indexing code. - In groups Fulltext...
