Titles differ between systems:

IPC: having base-exchange properties, e.g. crystalline zeolites, pillared clays

CPC: having base-exchange properties, e.g. crystalline zeolites

Full titles differ between systems:

IPC:

Catalysts comprising molecular sieves > having base-exchange properties, e.g. crystalline zeolites, pillared clays

CPC:

Catalysts comprising molecular sieves > having base-exchange properties, e.g. crystalline zeolites

CPC subdivides this area 6x more granularly than IPC with 5 additional codes.

5 codes are CPC-only extensions.

IPC defines codes here since 1974.
