Submission of an intention or a proposal for harmonised classification and labelling (CLH) of a substance, in accordance with the CLP Regulation (EC) 1272/2008

Intentions on CLH proposals provide information to ECHA and to the stakeholders about planned CLH dossiers. Dossier submitters are therefore encouraged to provide to ECHA an intention as early as possible in the preparation of the CLH dossier. Intentions are published in the Registry of Intentions (RoI) on ECHA's website to inform all interested parties about the CLH dossiers that are under preparation and to avoid situations where two or more dossiers are prepared for the same substance at the same time. If the submitter of an intention agrees, their contact details may be published with the intention, allowing other parties to provide any relevant information on the particular substance and the hazard classes concerned directly to the prospective dossier submitter.

This webform is used for the submission of :
  • CLH Pre-intentions
  • CLH intentions (and any updates to the information)
  • CLH proposals
  • RCOM documents
 Who should submit a CLH intention and CLH proposal?

Fields marked with * are required. Other information is only required if changed from previous submissions on the same external identifier.
