CPV code 44425400 designates Grout packers in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
44425400 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 44425000 (Rings, seals, bands, sticks and grout packers).
