REACH Metals Gateway

Manganese [Mn]

The Manganese REACH Administration (MARA)  is a non-profit making industry association  formed in 2008 with a common interest in fulfilling the requirements laid down by the EU REACH regulation. It's members, 43 at birth but only 34 ten years on, represent alloy producers (special preparations) and manufacturers and importers of inorganic manganese-based substances.

The Mn consortium is responsible for registering 12 Mn-based substances, including Mono-constituents, special preparations and UVCB's at the greater than 1000tpa tonnage band.  All the lead registrants dossiers from the Mn Consortium substances have been submitted to ECHA. 

Further information on the Mn Consortium is available from the Secretariat (Dr Doreen McGough) and on the Mn consortium web page -
