Registered substances

Registered substances

The data comes from registration dossiers submitted to ECHA by the date indicated as last update. The Total Tonnage Band is compiled from all the dossiers with two exceptions; any tonnages claimed confidential and any quantity used as an intermediate to produce a different chemical. The Total Tonnage band published does not necessarily reflect the registered tonnage band(s).

Please note that some of the information on registered substances may belong to third parties. The use of such information may therefore require the prior permission of the third party owners. Please consult the Legal Notice for further information.

Please note that information on chemical properties of registered substances is directly accessible via eChemPortal

Please note, that publication of REACH registration data is currently suspended until the end of November 2019 because of IT development work. During this period ECHA will not publish any new data from REACH registrations. At the beginning of December 2019, ECHA will publish all non-confidential data from dossiers submitted or updated during the break, and will resume the regular daily updates of the database.

We apologise for any inconvenience caused.

Last updated 05 December 2019. Database contains 22568 unique substances and contains information from 96887 dossiers.
