Notes

(1)

In groups C10L 1/12 to C10L 1/30, in the absence of an indication to the contrary, a compound is always classified in the last appropriate place.

(2)

A metal salt or an ammonium salt of a compound is classified as that compound, e.g. a chromium sulfonate is classified as a sulfonate in group C10L 1/24 and not in group C10L 1/30.
