CPV code 42921200 designates Machinery for filling or closing bottles, cans or other containers in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
42921200 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 42921000 (Machinery for cleaning, filling, packing or wrapping bottles or other containers).
