CPV codes: which category is your business?

Common Procurement Vocabulary (CPV) is the 8-digit taxonomy used in every EU tender notice. Right filtering starts with knowing your CPV codes — a quick tour of construction, engineering, IT, healthcare, and services.

CPV (Common Procurement Vocabulary) has been mandatory in EU procurement since 2003. Every notice carries at least one 'main CPV' and optional 'additional CPV' codes. A well-tuned CPV filter cuts through the 20,000+ daily notices to only the ones you can actually bid on.

Structure: 45123456-7

  • First 2 digits — sector (45 = Construction)
  • Digits 3-4 — sub-category (45.10 = Site preparation)
  • Digits 5-6 — detail (45.10.11 = Demolition)
  • Digits 7-8 — specific work (45.10.11.00 = Building demolition)
  • Last digit — checksum

Most common CPV headers for cross-border firms

  • 45 — Construction works
  • 50 — Maintenance & repair
  • 71 — Architectural & engineering services
  • 72 — IT services, software development
  • 73 — R&D
  • 79 — Consulting, business services
  • 33 — Medical devices, pharma
  • 34 — Transport equipment
  • 42 — Industrial machinery
  • 31 — Electrical machinery & materials

Common construction/infrastructure sub-codes

  • 45210000 — Building construction
  • 45220000 — Engineering works (bridges, tunnels)
  • 45230000 — Pipelines, transmission
  • 45260000 — Roofing + insulation
  • 45310000 — Electrical installation
  • 45320000 — Insulation (thermal, sound)
  • 45330000 — Plumbing + HVAC
  • 45420000 — Joinery + interior

Filtering strategy

In BidIndex, add 2-4 CPV codes to a filter — too broad ('45') gives you 200+ notices/day; too narrow (45231000) misses opportunities. Sweet spot: 2-digit umbrella + 1-2 sub-codes. Example: electrical contractor → 45310000 + 71314000 (energy efficiency consulting).

A wrong CPV filter turns BidIndex into a spam folder. 20 minutes with the CPV list saves 200 hours of noise per year.
