European Commission communication establishing the 2017 critical raw materials list, expanding coverage to 27 materials and introducing a revised scoring methodology; but removing magnesite, whose supply risk score had dropped below the criticality threshold in the updated assessment. The removal followed a formula revision that gave greater weight to EU import reliance; because the EU produces magnesite domestically, the formula assigned it near-zero supply risk regardless of how concentrated global production is. The 2017 decision illustrates the structural asymmetry built into every CRM methodology to date: domestic self-sufficiency is treated as a proxy for supply security, a logic that holds only as long as domestic capacity is sustained.
