The homepage for the Substance Information Exchange Forums (SIEFs) of substances covered by the SDIOC for REACH registrations in 2010, 2013 as well as foreseen registrations till 2018 (listed on this page) is currently up-to-date. For more information on SIEF activities, please visit the substance-specific webpage.

A SIEF is formed for a particular substance pre-registered for REACH. The SIEF Members are all the pre-registrants who intend to register the same substance or data holders who own endpoint specific data which may be relevant for REACH registration. A SIEF has no prescribed legal form, but it is a forum to share data and to organise the development of the dossier required for REACH registration. Pre-registrants can participate as a SIEF member at different activity levels: very active, involved, passive, and dormant.  All SIEFs shall remain operational until 1 June 2018.

The Secretariat of the SDIOC is acting as SIEF Facilitator on behalf of the respective Lead Registrant for each of the considered SDIOC substances.

SDIOC has conducted a Sameness Survey for the considered sulfur dioxide based substances. Respondents that participated in the Sameness Survey are considered to be Active Members of the SIEF. The Secretariat of the SDIOC will work with Active Members within each SIEF. If you would like to become an Active Member, please E-mail the SIEF Facilitator []

Pre-registrants that have not yet participated in the Sameness Survey for the SDIOC substance can access it on the webpage for the considered substance. Thus, in the future, new respondents to the Sameness Survey may also become Active Members.

SIEF activities

The SDIOC prepared the registration dossiers for 14 substances and is currently preparing an additional dossier for one substance, i.e. the IUCLID file, in cooperation with the SIEF for the covered SDIOC substances. The nominated Lead Registrants for the specific sulfur dioxide based substances submitted the REACH Registration Dossier already in November 2010 and in the years 2012-2013. One dossier is foreseen for submission in October 2015. All other co-registrants will refer to it when submitting their registration.

Intending registrants will be able to purchase a Letter of Access (LoA) from the SDIOC. An LoA will grant the permission to refer to the technical dossier for the specific purpose of REACH registration. As a Chemical Safety Report (CSR) is part of the technical dossier, it can be included in the data package. The costs of an LoA has been recalculated in 2015 by the SDIOC. These costs are provided in the LoA documents specific for each tonnage band and can be obtained here

For specific SDIOC substances, please visit the respective webpage for more information and a status update of SIEF activities.

The SDIOC is acting as SIEF facilitator for SDIOC member pre-registrants who indicated their willingness at Pre-Registration to conduct this activity for the substances listed on this page.
