Notification of Classification & Labelling

There is no notification by a « Lead Notifier ». However, as a service to industry, the Nickel REACH Consortia will freely communicate the information required for classification and labelling of the substances covered by the Consortia. This information is provided in .i6z (IUCLID 6) format each time a potential registrant intends to join the Joint Submission and includes Section 1.1 (reference substance), 1.2 and 2.1. It is up to the company to complete Section 1.1 (legal entity specific information), to review section 1.2 and to fill section 1.4, since these sections are company-specific.

You can check here the classification of pure substances (without impurities) covered by the Nickel REACH Consortia.

Updates and SIEF progress overview

The Nickel REACH Consortia has established a voluntary procedure to update all the REACH Registration dossiers on a regular basis. These updates are based on two levels of priorities set by the Consortia members. According to these priorities, the most urgent updates (including the incorporation of new exposure scenarios to cover new identified uses, new DNELs or PNECs) are submitted every year. Other updates, such as the inclusion of new exposure data in the existing exposure scenarios, will be updated every two years. 

In addition, a complete revision of all the exposure scenarios was completed in 2017 for all the uses and substances covered by the Nickel REACH Consortia. The continuous collaboration of manufacturers and downstream users is crucial to improve the exposure scenarios
