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 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. in a consortium or other form of co-operation) to carry out their individual REACH obligations. All SIEFs shall remain operational until 1 June 2018.
A SIEF is only formed when pre-registrants have agreed that they manufacture or import the same substance. They 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 needs 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, two 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
