CPV code 24951400 designates Chemically-modified fats and oils in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
24951400 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 24951000 (Greases and lubricants).
