2019 GA meeting May 8 in Madrid


The 2018 GA meeting which took place on Thursday 3 May 2018 in Brugge, Belgium saw an increase in attendance from 2017. Hosted by Prince-Erachem, the meeting which lasted 5 hours saw several deliberations related to the last REACH deadline and its consequences thereafter including the possible re-structuring of the consortium.  Some key decisions taken by way of vote are as follows:

Some highlights:

  • Future structure of Mara: A more streamline structure to be established if the organisation is to continue functioning infinitely or in the event of a complete closure its mandate and members to be incorporated within the Mn trade association –The IMnI. Discussions are still on-going  
  • Collaboration: A clearly defined pathway for collaboration between Mara and the IMnI was established
  • Data-sharing Regulation: Approval of the reimbursement structure (to be executed in phases) in accordance with regulation 2016/9
  • Approval of the 2018 workplan and budget

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).


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.
