Two Clocks, One Supply Chain: The Rare Earth Reckoning Arrives November 10

Highlights

• China's 2025 rare-earth export-control suspension expires November 10, 2026, potentially reactivating controls over materials, technology, and supply-chain access beyond China's borders.
• U.S. DoD DFARS restrictions expand January 1, 2027 to cover the entire NdFeB supply chain from mining through finished magnets, forcing defense buyers toward traceable non-Chinese sources.
• Western policy clocks move in weeks, compliance clocks in months, but industrial replacement clocks move in years—creating what REEx calls the Transition Vulnerability Window.
• Heavy rare-earth price spreads reveal the cost of sovereignty: dysprosium oxide in Europe traded at roughly 4.9 times the Chinese domestic price as of late August 2026.
• Aggregate rare-earth tonnage is misleading; the REEx Missing Molecules Problem shows that large resources do not guarantee availability of the specific element, purity, form, and provenance actually needed.
