Registry of restriction intentions until outcome

The registry of restriction intentions until outcome lists the intentions and Annex XV restriction proposals received by ECHA.

A restriction proposal may be prepared by a Member State or by ECHA at the request of the Commission or on its own initiative for substances in the Authorisation List. It is a legal requirement for a Member State to notify ECHA of its intention to prepare a restriction dossier. The advance notice enables interested parties to plan and prepare for commenting later on.

Interested parties can follow the progress of a proposal through the restriction process, from the notification of the intention to the adoption of the final opinions by the Committee for Risk Assessment (RAC) and the Committee for Socio-economic Analysis (SEAC), and the adoption of the restriction by the European Commission.

Stakeholders are encouraged to submit any relevant information to the dossier submitters during the preparation of the restriction proposal and during the consultations. Information to motivate any exemptions to the scope described in the intention is particularly useful to receive in the preparatory phase of the dossier.

Further substance information
Details on the scope of restriction
Restricting the use of certain chromium (VI) substances.
Reason for restriction
The number of applications for authorisation for the use of certain Cr(VI) substances has far exceeded the predictions at the time of inclusion of the substances in REACH Annex XIV, and the approach envisaged for regulating Cr(VI) substances (authorisation) is no longer appropriate to control the risk to human health posed by these substances. The Commission is therefore requesting ECHA to prepare a restriction dossier in line with the requirements of Annex XV.
The Dossier Submitter will take stock of the granted authorisations as well as processed and pending applications for authorisations for the chromium (VI) substances in scope of the restriction proposal.

Stakeholders are requested to provide relevant information to the Dossier Submitter. If justified based on robust risk and socio-economic information the Dossier Submitter may propose derogations from the proposed restriction. If a derogation is not proposed by the Dossier Submitter then it will be incumbent on the relevant stakeholders to do so during any consultation process with a full risk and socio-economic justification accompanying it.

Update 8 May 2024: Based on ECHA findings and by request from the Commission, the Intention has been amended to extend the scope and timeline to prepare the Annex XV dossier. The Commission amendment to the initial request can be found at the following link:
In addition to entry 16 on chromium trioxide, and entry 17 on acids generated from chromium trioxide and their oligomers currently listed on REACH Annex XIV, the scope of the Annex XV dossier also covers REACH Annex XIV entries 18, 19, 20, 21, 22, 28, 29, 30, 31, and Cr(VI) substances not listed in Annex XIV but with the potential to lead to regrettable substitution, in particular barium chromate.
