In general terms, the SIEF is where participants 'self-organise' to compile the technical dossier required for REACH Registration.  SIEF members can opt for any of four different categories of involvement in the SIEF process.

The Secretariat of the Cadmium Consortium is acting as SIEF Facilitator, on behalf of the Lead Registrant, for each of the substances.  The Consortium is a separate activity to the SIEF.  Intending registrants are welcome to join the Consortium

Who's in a SIEF?

  • EU Manufacturers, EU Importers, Only Representatives of Non-European Manufacturers, Data-Holders

What are the main activities in a SIEF? 

  • Election of Lead Registrant
  • Agree upon information to be jointly submitted:
    • Joint submission of the hazard data-set and any testing proposals is mandatory
    • Joint submission of the Chemical Safety Report and Guidance on Safe Use is voluntary
  • Conduct data-sharing
  • Agree upon Classification & Labelling of the substances

The REACH Registration Dossier will be submitted by the Lead Registrant, and all other registrants will refer to it when making their registration.  The registration dossier is being prepared by the Zinc Consortium, in liaison with the SIEF members. 

SIEF members will be able to purchase a letter of access from the Consortium that grants a 'permission to refer' to the Dossier for the specific purpose of REACH registration.  Please click on the link to find out the prices.
