CPV code 42418400 designates Carousel storage and retrieval machines in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
42418400 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 42418000 (Lifting, handling, loading or unloading machinery).
