Registry of CLH intentions until outcome

The registry of classification and labelling (CLH) intentions until outcome lists the intentions and proposals received by ECHA for a new or revised harmonised classification and labelling of a substance. The proposals are submitted by Member State competent authorities, manufacturers, importers or downstream users.  

Interested parties can follow the progress of a proposal through the CLH process, from the notification of the intention to the adoption of the opinion of the Committee for Risk Assessment (RAC). The advance notice enables interested parties to plan and prepare for commenting later on.

Anyone with relevant information on the identity or hazard properties of a substance is encouraged to provide this information to the dossier submitter during the early stages of the process, or at the latest during the consultation.

Where an opinion has been adopted by RAC, the status is indicated as ‘Opinion Adopted’.

Note: The classification tables for those substances that have been reviewed are listed in the ‘Corrigenda to the RAC opinions’ document.

Active substance in Biocidal Products
OIT was originally included in Annex I to Directive 67/548/EEC following a proposal submitted by the Danish Toxicology Centre In March 1993. The harmonised classification in Annex VI of CLP was translated from the DSD classification. This CLH proposal includes a reassessment of studies used at that time and also more recent studies carried out after the preparation of the original C&L document.
