CPV code 42665000 designates Metal-spraying machinery in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
42665000 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 42660000 (Soldering, brazing and welding tools, surface tempering and hot-spraying machines and equipment).
