CPV code 80620000 designates Training and simulation in firearms and ammunition in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
80620000 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 80600000 (Training services in defence and security materials).
