The role of Lead Registrant is laid down by the REACH Regulation and it is mandatory for each SIEF.

Lead Registrants preparing for the 2010 registration deadline are advised to inform ECHA of their nomination by using the link below:

Substances covered: 2025 () () check your substance(s) EC number in the link above to see if your SIEF/LR is progressing N.B. The table includes also information about candidate lead registrants.

As the name suggests, SIEFs are there to ensure that data is shared. Keep that in mind as you work in your SIEF.

This web section gives a brief overview of the critical information on SIEFs and how to prepare for registration under REACH. It also provides links to the most important guidance and other support documents published by ECHA.

The highlights

Companies that have pre-registered a substance with a 2010 registration deadline will find short summary of getting active in a SIEF.

Pre-registration

Basic information about pre-registration for companies entitled to make “late” pre-registrations is here. The arrow buttons above “Further information” heading will allow you to navigate easily between the pre-registration steps.

Pre-SIEF

The concept of pre-SIEFs was not foreseen in the REACH Regulation, but was introduced, with support from industry, to bring pre-registrants together and facilitate SIEF formation. This page provides information on how REACH-IT allows a pre-registrant to see who else has pre-registered the “same” substance.

SIEF Formation

The transition from pre-SIEFs to SIEFs happens outside REACH-IT and the responsibility lies with companies. A SIEF is formed when companies have agreed that their substance is the same. General best practice is provided on this page.

SIEF Duties

SIEFs consist of companies that pre-registered substances with the same chemical identity, and other organisations that have indicated they own data on the substance. The duties of participants in SIEFs are explained here.

Lead Registrant

The Lead Registrant (LR) is a mandatory role in a SIEF, although REACH does not specify the rules for their election. This page explains the duties and commitments of the Lead Registrant, acting with the agreement of the other assenting registrants.

Data Sharing

Data sharing is mandatory for studies on vertebrate animals. REACH has several provisions to facilitate the sharing of data between registrants. This page provides the general concepts of data sharing.

Registration

When potential registrants in a SIEF have shared and assessed the available data, the LR prepares the common parts of their registration dossier, the so-called joint submission. This page provides information on how the joint registration is to be prepared and jointly submitted.

Software tools

A number of companies have developed software tools to try to help SIEF formation. ECHA has been made aware of a number of them and they are listed here.
