CPV code 24322400 designates Phenols and derivatives in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
24322400 is a leaf code — the most specific level of its branch — so it can be used directly as the main CPV code of a contract notice. If it does not quite fit, check the neighbouring codes under 24322000 (Alcohols, phenols, phenol-alcohols and their halogenated, sulphonated, nitrated or nitrosated derivatives; industrial fatty alcohols).
