The Consortium structure includes a Steering Committee and a technical Coordination Group and is managed by REACHCENTRUM SA. The Consortium is open to all manufacturers/ importers/ only representatives (as defined in the REACH Regulation), who have the obligation to register under REACH one or more Consortium substances (on their own, in preparations or in articles).

Cost for Letter of Access (LoA) and SIEF agreement

The Consortium offers letters of access for registration dossiers for each Consortium Substance to all interested parties who do not wish to join the Consortium, but do have an obligation to register the substance by any of the REACH deadlines (2010, 2013 or 2018).

Letter of Access

The LoA prices have been calculated and the LoAs are available at :

Additional details can be obtained via the Consortium Manager of ReachCentrum in charge of the Consortium.

SIEF communication

Based on pre-SIEF information from REACH-IT the Consortium has identified the need to communicate with multiple (> 1000) Legal Entity Contact Points or distinct email addresses. To ensure an efficient communication with such a large number of contacts and to comply with REACH transparency requirements, all Legal Entity Contact Points will be informed about the availability of all SIEF relevant information on this webpage and/or on REACH-IT:

  • Substance Sameness (See Substances covered section)
  • Lead registrant
  • Data sharing
  • Information on letters of access SIEF agreement
  • End-uses covered by the registration dossier and the Chemical Safety Report

Lead Registrant (LR)

All substances which have been registered in 2010 in this consortium have a confirmed LR.

Data sharing

The Consortium has available all the studies/data which are required. In case you would like to share your studies either as a registrant or as a data holder, please contact the Consortium Manager.
