Rare earth elements — Full commodity dossier

Supply structure and processing chokepoints

Primary mine production of rare earth elements is distributed across 13 tracked producer jurisdictions in the baseline model, representing a global output of 389,310 metric tons. The production base is led by China, which accounts for 270,000 metric tons or 69.4 percent of world output. The top three producing jurisdictions—China (69.4 percent), United States (13.1 percent), and Australia (7.4 percent)—collectively govern 89.9 percent of aggregate primary extraction.

Market concentration across primary extraction scores 5,072 points on the Herfindahl-Hirschman Index (HHI), positioning primary rare earth elements mining within the highly concentrated category. On standard antitrust and procurement vulnerability thresholds, an HHI exceeding 2,500 indicates acute structural concentration, where production decisions, fiscal adjustments, or local disruptions in the leading jurisdiction directly impact global supply availability.

The geological reserve base provides visibility into medium-term supply potential: China holds 51.6 percent of identified reserves in sovereign reporting^[1]. The reserve concentration index scores 3,371 HHI, compared to 5,072 for operating mine output. Because reserve concentration is lower than production concentration, the current supply tightness represents capital deployment decisions and downstream processing bottlenecks rather than absolute crustal scarcity.

Downstream conversion of raw ore or unrefined concentrate into refined specification product represents the principal point of commercial leverage. While mining output defines the physical volume ceiling, the chemical conversion stage—smelting, hydrometallurgical leaching, solvent extraction separation, and cathode electrowinning—is historically more concentrated than extraction itself. Commercial consumers requiring high-purity feedstocks must manage counterparty and operational exposure at the refining stage rather than at the pithead.
