Commission Regulation (EC) No 213/2008 is an EU regulation that establishes the Common Procurement Vocabulary (CPV) as a standardized classification system for public procurement within the European Union. The CPV is a hierarchical system that categorises and classifies goods, works, and services that are subject to public procurement procedures. The main purpose of this regulation is to enhance transparency, consistency, and interoperability in public procurement across EU member states. By using a common vocabulary, the CPV helps facilitate better understanding and communication among contracting authorities, suppliers, and other stakeholders involved in the procurement process.
