CPV code 32310000 designates Radio broadcast receivers in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
32310000 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 32300000 (Television and radio receivers, and sound or video recording or reproducing apparatus).
