New Data Availability System
A new Data Availability System is being developed by ECHA. To begin with this system will take over the responsibility of making REACH registration data available, once it is ready. We expect the first version to be publicly available by the end of 2023.
Since ECHA aims to devote our maximum effort to this new system, we can no longer maintain REACH registration data on the current Dissemination Platform. As such once the IUCLID format change begins on 19th May 2023 we will no longer update REACH registered substance factsheets. The factsheets will remain online, but will not be updated.
As a consequence, REACH registration data will likewise not be updated in Infocards, Brief Profiles, the Advanced search, or the Nanomaterials on the EU market portal. We will inform you of what you can expect in the new system, along with details of when and where to find it.
We appreciate your understanding in the meantime.
