CPV code 19143000 designates Imitation leather in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
19143000 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 19140000 (Leather of other animals, composite leather and other leather).
