Full titles differ between systems:

IPC:

Polymeric products of isocyanates or isothiocyanates > with compounds having active hydrogen > characterised by the isocyanates or isothiocyanates used > Polyisocyanates or polyisothiocyanates > having hetero atoms in addition to the isocyanate or isothiocyanate nitrogen and oxygen or sulfur

CPC:

Polymeric products of isocyanates or isothiocyanates > with compounds having active hydrogen > characterised by the isocyanates or isothiocyanates used > Polyisocyanates or polyisothiocyanates > having heteroatoms in addition to the isocyanate or isothiocyanate nitrogen and oxygen or sulfur

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.
