CPV code 44332000 designates Rods (construction) in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
44332000 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 44330000 (Bars, rods, wire and profiles used in construction).
