U.S. Defense Supply Chain Shake-Up: Rare Earth Magnets Face a New Traceability Test

Policy pressure on the U.S. rare earth and magnet supply chain is rising. On July 20, 2026, the White House issued an executive order requiring critical materials and components used in defense procurement to shift more clearly toward U.S. domestic and allied sources. Some waiver mechanisms will also be tightened starting January 1, 2027.

Industry Insight | Arafura's India Offtake Agreement Signals a New Phase in the Global Rare Earth Magnet Supply Chain

Australian rare earth developer Arafura Rare Earths has announced a binding offtake term sheet with a special purpose vehicle (SPV) established by an Indian industrial group. Under the agreement, the Nolans Project will supply up to 500 tonnes per year of rare earth materials, including NdPr (Neodymium-Praseodymium), Dysprosium (Dy), and Terbium (Tb), for an initial five-year period with an option to extend for an additional two years.
