2020 GA Meeting May 6th in Kristiansand (KRS), Norway


The 2019 GA meeting which took place on Wednesday 8 May 2019 in Madrid, Spain was a resounding success. Hosted by FerroGlobe, the meeting which lasted 4 hours saw several deliberations related to the consortium governace, dossier updates and classification & labelling. Some key decisions taken by way of vote are as follows:

Some highlights:

  • Executive Committee: A new Chairmanand  a new 2nd Vice Chairman were appointed, meanwhile the 1st Vice Chiarman was maintained to enure continuity 
  • Dossier updates: Reveal changes in classification and labelling if compared to the 2010 submitted dossiers
  • Approval of the 2018 workplan and budget
  • Brexit and data: Mara will continue to support REACH registration inside and outside the EU (UK REACH inclusive) but at a charge yet to be determined 

Trimanganese tetraoxide (EC :215-266-5; Cas :1317-35-7)

The lead dossier was submitted in 2010 with no testing proposals. In July 2013 a compliance check was initiated, requesting more details with regard to the following information requirements/updates:

  • Annex IX 8.7.2 (pre-natal developmental study, oral route, OECD 414)
  • Annex X, 8.7.3 (two-generation reproductive toxicity study, oral route, OECD 416 or an extended one generation reproductive toxicity study, OECD 443)

By 27 September 2013 the consortium secretariat on behalf of the lead registrant had responded to the ECHA’s draft decision concerns, highlighting the lack of need for such animal-intensive studies and encouraging the use of already available data within the manganese data pool.

In July 2016 ECHA notified the competent authorities of the member states of its draft decision together with the registrant's comments. No member state commented on the draft decision. A final decision requesting the following study was published in September 2016:

  • Pre-natal developmental toxicity study (Annex IX, 8.7.2.; test method: EU B.31/OECD 414) in rats or rabbits, oral route - while a decision was not yet reached on the two-generation reproductive toxicity study endpoint, 

The Annex IX 8.7.2 (pre-natal developmental study, oral route, OECD 414) study, now completed (May 10, 2018) revealed several fetal effects. Litter size and mean fetal weights were slightly reduced. Embryo-fetal survival was considered unaffected by treatment, but fetal development was adversely affected with bent scapula(e); bent radius/ulna/fibula; short/bent/and thickened humerus with associated medially thickened/kinked/incompletely ossified ribs.

Therefore, the No-Observed- Effect-Level (NOEL) for maternal toxicity was 750 mg/kg/day and the No-Observed-Adverse-Effect-Level (NOAEL) for embryo-fetal toxicity was concluded to be 250 mg/kg/day.

The updated dossier was submitted earlier this year (Q1, 2019) with new available data from ECHA's compliance checks request, new uses and a new CLP classification. All co-registrants that had met their financial obligations were provided with the following:

1) Updated CSR

2) Exposure scenarios for their eSDS

3) Updated CLP classification.

This dossier has undergone significant amount of work post this year's  Q1 submission. In the end, ECHA accepted  the Pre-natal developmental toxicity study (Annex IX, 8.7.2.; test method: EU B.31/OECD 414) in rat, oral route study.  However, in Q3 another letter from ECHA requested that several ecotoxicology endpoints  be reveiwed  or a corresponding study be carried out.  To this end a dossier update is anticipated by end of year - 2019.

Note: Post 2018, the consortium will no longer invoice co-registrants  for ECHA requested studies retrospectively. All compliance check related work will require co-registrants to contribute their share before any dossier update work can begin.
