Changes to completeness checks of REACH registrations

Corrigendum 11 April 2023: Following a postponement of the next IUCLID release, the new and amended completeness checks will take effect as of 1 June 2023. 

The European Commission amended some of the information requirements for registering chemicals under REACH in 2021 and 2022. As of 1 June 2023, ECHA will start checking both new registrations and updates to existing ones against the revised requirements.

Helsinki, 23 January 2023 – ECHA carries out a completeness check on each incoming registration as set out in Article 20(2) of the REACH Regulation.

The new and amended checks will take effect as of 1 June 2023 and will apply to both new registrations and updates of existing ones. Registrants should, therefore, prepare for the changes as registrations submitted before may no longer pass the completeness check.

The new and amended checks concern:

  • Substance identity: ensuring correct and consistent identification of a substance’s boundary composition and its constituents and additives based on clarifications made to Annex VI.
  • Standard information requirements based on Annexes VII-XI: supporting registrants in reporting information for endpoints concerning mutagenicity, degradation and aquatic toxicity based on Annex VII-XI information requirements. Registrants adding a new weight-of-evidence adaptation will be prompted to provide arguments for the approach in a more structured format.

In parallel, limited revisions have been made to the completeness check in other areas, such as use information.

The IUCLID validation assistant will also be updated with the amended completeness check rules when the new version of IUCLID is released at the end of April 2023. Registrants are encouraged to use the validation assistant to check their registrations before submitting them to ECHA.
