IUCLID plays a central role in the IT environments of all organisations that manage scientific data on chemicals in a regulatory context, for example under the OECD HPV, EU Biocides, and EU REACH:

  • Industry stakeholders
  • EU Member States
  • The European Chemicals Agency (ECHA)

IUCLID is the essential tool for any organisation or individual that needs to record, store, submit, and exchange data on chemical substances in the format of the OECD Harmonised Templates.
