Special rules of classification

In groups A23J 3/04-A23J 3/20, in the absence of an indication to the contrary, classification is made in the last appropriate place.

Subject matter classified in groups A23J 3/22-A23J 3/30 is also classified in groups A23J 3/04-A23J 3/20, if the nature of the protein is of interest.
