Notes

(1)

In this class, in the absence of an indication to the contrary, a compound is classified in the last appropriate place. [3]

(2)

Processes using enzymes or micro-organisms in order to:

(i)

liberate, separate or purify a pre-existing compound or composition, or to

(ii)

treat textiles or clean solid surfaces of materials

are further classified in subclass C 12 S. [5]
