MATERIALS FOR MISCELLANEOUS APPLICATIONS, NOT PROVIDED FOR ELSEWHERE

17/

Soil-conditioning materials or soil-stabilising materials (fertilisers C05; consolidating by placing solidifying or pore-filling substances in the soil E02D 3/12; consolidating boreholes for oil or gas recovery E21B 33/00) [3]

Notes

(1)

This group covers mixtures of soil-conditioning or soil-stabilising materials with fertilisers characterised by their soil-conditioning or soil-stabilising activity. [6]

(2)

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. [6]

(3)

For the purpose of classification in this group, the presence of fertilisers in the composition is not taken into account. [6]

(4)

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. [6]

(5)

In this group, it is desirable to add the indexing codes of groups C09K 101:00 to C09K 109:00. The indexing codes should be unlinked. [6]
