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

The result of the search ‘Substance has nanoform’ returns all factsheets containing data related to nanomaterials. However, this does not mean that a registration covering nanoforms of the substance has been submitted in line with the revised annexes of REACH by all the registrants concerned. Note that since 1 January 2020, before manufacturing or importing a nanoform of a substance, the operators concerned must submit the required nano-specific information to ECHA using IUCLID version 6.4 (released on 30 October 2019).

Last updated 25 February 2020. Database contains 22699 unique substances and contains information from 98559 dossiers.
