NOTE
-
This group covers mixtures of soil-conditioning or soil-stabilising materials with fertilisers characterised by their soil-conditioning or soil-stabilising activity.

This group does not cover mixtures of soil-conditioning or soil-stabilising materials with fertilisers characterised by their fertilising activity which are covered by subclass C05G .

For the purpose of classification in this group, the presence of fertilisers in the composition is not taken into account.

In groups C09K 17/02 to C09K 17/50 , in the absence of an indication to the contrary, materials are classified in the last appropriate place.
