CPV code 50116510 designates Tyre-remoulding services in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
50116510 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 50116500 (Tyre repair services, including fitting and balancing).
