CPV code 42212000 designates Machinery for processing cereals or dried vegetables in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
42212000 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 42210000 (Food, beverage and tobacco-processing machinery).
