European Commission establishing the 2014 critical raw materials list, expanding coverage from 14 to 20 materials and adding magnesite for the first time on the basis of concentrated global production in China and Russia and high economic importance to EU industry. The 2014 assessment accompanied a technical review of 54 candidate materials evaluated against supply risk and economic importance thresholds drawn from the 2010 and 2011 methodology revisions. Magnesite’s inclusion in 2014 would be reversed in 2017 after an updated scoring exercise lowered its supply risk below the criticality threshold; an oscillation that reflects the sensitivity of criticality designation to methodological choices rather than underlying physical supply conditions.
