Substance Information Exchange Fora (SIEF)
Substance Information Exchange Fora (SIEF)
What is a SIEF?
Under REACH, a SIEF is formed for each pre-registered substance with the same identity. SIEF participants are either potential registrants or data holders. A SIEF has no prescribed legal form, but is a forum within which to share data, facilitate the registration process. and agree on classification and labelling (C&L) of the substance. Participants in a SIEF are free to organise themselves as they see fit (e.g. by means of a consortium or some other form of co-operation) in order to fulfil their individual REACH obligations. All SIEFs will remain operational until 1 June 2018.
A SIEF is only formed when pre-registrants have agreed that they manufacture or import the same substance. The pre-registrants will share and assess data and prepare common parts of the registration (joint submission).
IMPORTANT: ENSURE THAT YOUR CONTACT DETAILS IN REACH-IT ARE UPDATED AND ACCURATE AS SIEF COMMUNICATIONS WILL USE THIS INFORMATION.
What must I do?
All SIEF participants shall:
- Request missing information from other participants
- React to requests for information from other participants
- Provide other participants with existing studies upon request
- Collectively identify the need for further studies to comply with registration requirements
- Make arrangements to perform any identified studies
- Agree on classification and labelling of the substance
- Nominate a Lead Registrant for the joint submission process (OSOR)
Third-party data holders in the SIEF who do not intend to submit a registration:
- Must respond to a query from potential registrants if they hold related data
- Are not entitled to request data
During March - June 2009, 2 internet-based survey forms were sent to each pre-registrant of Mn-based substances to the email address in the ECHA REACH-IT system. These surveys included:
- Substance identity sameness agreement
- SIEF formation
- Lead registrant nomination
- A request for data holders to come forward, and
- SIEF participant's registration intention
The SFF dialogue box in REACH-IT, where available, includes results from these surveys.
