Arnold Magnetic Technologies Warns Western Buyers: China's Rare Earth Shock Has Become an Industrial Reset

Highlights

• China controlled 90% of global refined magnet rare-earth output and 90%+ of sintered permanent-magnet production in 2024, leaving Western buyers highly exposed.
• Arnold Magnetic Technologies CCO Aaron Williams urges manufacturers to build inventory, traceability, and Western manufacturing capacity beyond just-in-time sourcing.
• REEx modeling challenges the industry's 2028 'genuinely secure' timeline, noting the IEA estimates Western projects would meet only ~20% of magnet demand by 2035.
• U.S. defense procurement restrictions on NdFeB magnets expand significantly on January 1, 2027, covering the full supply chain from mining through finished magnets.
• Building true supply chain independence requires separation, metallization, alloying, and qualified magnet production at commercial scale—not just mine announcements.

China’s April 2025 rare-earth export controls did more than delay shipments—they exposed how little of the permanent-magnet supply chain the West actually controls. Aaron Williams, Chief Commercial Officer of Arnold Magnetic Technologies, argues (opens in a new tab) in Electric & Hybrid Vehicle Technology International that manufacturers must move beyond just-in-time sourcing toward inventories, traceability, and Western manufacturing. A theme Rare Earth Exchanges® (REEx) covers frequently. His diagnosis is largely right. His expectation of a “genuinely secure” position by 2028 is harder to accept based on REEx modeling. China accounted for 90% of global refined magnet rare-earth output and 90%+ of sintered permanent-magnet production in 2024.

REEx Insight — Inventory Buys Time. Metallization Buys Independence.

The most important issue is provenance. China’s April 4, 2025 controls imposed export licensing on specified samarium, gadolinium, terbium, dysprosium, lutetium, scandium, and yttrium materials—including certain metals, alloys, oxides, compounds, and permanent-magnet materials.

Six months of inventory can cushion a supply shock. It cannot manufacture sovereignty. The West’s deeper challenge remains building an industrial chain spanning separation, oxide-to-metal conversion, alloying, and qualified magnet production at commercial scale.

That becomes especially important on January 1, 2027, when U.S. defense procurement restrictions expand for NdFeB magnets to encompass the supply chain from mining neodymium, iron, and boron through finished magnets originating in China and other covered countries, subject to statutory exceptions.

The West Is Building—China Still Owns the Scale

Williams is right that alternatives are emerging. MP Materials is building an increasingly integrated U.S. mine-to-magnet chain. USA Rare Earth is assembling another through magnet manufacturing and upstream resource investments. Lynas provides substantial non-Chinese mining and separation capacity. But here the article moves faster than the factories.

Western projects are real; Western independence is not. New mines alone cannot solve a midstream and downstream problem. Separation must feed metals; metals must become alloys; alloys must become qualified magnets—and each stage must operate economically at scale. And that is the article’s biggest question based on the REEx modeling. According to Williams, “…the industry expects meaningfully better footing by 2027 and a genuinely secure position by 2028.” Yes, 2028 may bring considerably more Western capacity. However, REEx suggests that year should not yet be confused with security. So based on our understanding, Williams has the direction right. The clock is the questionable part.

The Dangerous Comfort of the 2028 Narrative

The greatest danger may be believing our own Western talking points. Announcing mines, grants, magnet plants, and 2027–2028 production targets is not the same as rebuilding an industrial ecosystem that China spent decades constructing. The numbers remain brutal: China’s near monopoly position on refining and magnet/component/assembly production, while the IEA estimates that even existing and announced projects outside China would satisfy only about 25% of ex-China refining demand and less than 20% of magnet demand by 2035.

This is not a three-year construction project. It requires sustained industrial policy, patient capital, permitting reform, skilled metallurgists and engineers (ubiquitous workforce development programs), specialized equipment, economically viable separation and metallization, alloy production, magnet qualification, secure heavy-rare-earth feedstocks, competitive energy and chemicals, recycling, traceability, guaranteed demand, and enough operating experience to move plants from PowerPoint capacity to reliable commercial yield.

The risks extend further: Chinese price competition can strand Western projects; export controls can reach equipment and technology as well as materials; shortages of Dy, Tb, and other critical inputs can cripple an otherwise complete NdFeB chain; defense qualification can lag factory commissioning; political cycles can outlast subsidies; fragmented Western projects can produce mismatched capacity between mines, separators, and magnet plants; and dependence can simply migrate from Chinese magnets to Chinese feedstock, machinery, or know-how.

Yes, under the Trump administration 2.0 the U.S. has taken a leading position for the West, finally recognizing the problem, but recognition should not be mistaken for readiness. The real test is not how many projects are announced—it is whether an independent supply chain can keep Western factories and defense systems running when Chinese supply is no longer available.
