CPV code 50190000 designates Demolition services of vehicles in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
50190000 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 50100000 (Repair, maintenance and associated services of vehicles and related equipment).
