Recommendations for inclusion in the Authorisation List

Recommendations for inclusion in the Authorisation List

Nested Applications


The REACH Regulation requires that ECHA recommends from the "Candidate List" priority substances for inclusion in Annex XIV (the "Authorisation List") to the European Commission, taking into account comments received from interested parties and the opinion of the Member State Committee. The European Commission finally decides, which substances will be included in Annex XIV and what the associated entries will be.

The below table includes all Candidate List substances that have been included in ECHA's draft or final recommendations for inclusion in Annex XIV. The "Status"- column indicates whether the substances have been included in a draft recommendation, recommended for inclusion or are already included in Annex XIV. Further details and documents relevant for the recommendations can be found by clicking on the "Details" next to the substances.

Substances not recommended in a given round (Status: “Not recommended in this round”) are re-assessed in subsequent rounds along with the other substances on the Candidate List. They may be included in future recommendations. Therefore, it is advisable to search the table by substance (Name/EC/CAS) to capture the most up-to-date status.
