Dysprosium

What Is Dysprosium

Dysprosium is element 66 — a heavy rare earth element (one of the lanthanide series of metals, so named because they were historically difficult to separate from each other and occur together in the same ore deposits) with a narrow but irreplaceable industrial function. It is not a metal most people have heard of. It is the metal that makes the motors in electric vehicles work at operating temperature.

The function is specific. Dysprosium is added in small quantities — typically 1–6% by weight — to NdFeB permanent magnets (neodymium-iron-boron — the strongest type of permanent magnet commercially available, used in EV motors, wind turbine generators, and precision industrial equipment) to raise their coercivity (resistance to demagnetisation — the property that keeps a magnet working under heat and mechanical stress rather than losing its magnetic force). Without dysprosium, NdFeB magnets begin losing their magnetic properties above approximately 80 degrees Celsius. An EV motor under load routinely exceeds that temperature. A wind turbine generator operates in conditions that regularly exceed it. Without dysprosium, the magnet weakens, the motor loses efficiency, and the application degrades.

If you have read the Neodymium page on ScarceEarth, this is the next part of the same story. Neodymium provides the magnetic force. Dysprosium keeps that force working when the temperature rises. Dysprosium is not an alternative to neodymium — it is an additive that makes neodymium-based magnets functional in real-world operating conditions. You cannot have the high-performance magnet without both.

The quantities involved are small per unit — a typical EV motor uses roughly 50–100 grams of dysprosium per vehicle. But at scale — millions of EVs, thousands of wind turbines — those grams compound. Global dysprosium production runs at only approximately 2,000 tonnes per year. The entire addressable market is thin.

Where It Comes From

China dominates dysprosium supply with even greater concentration than neodymium. The reason is geological. Dysprosium is a heavy rare earth element, and heavy rare earths are primarily sourced from ionic clay deposits (also called ion-adsorption clay deposits — ore bodies where rare earth elements are loosely bound to clay particles rather than locked in hard rock minerals, making them extractable by chemical leaching but also geographically concentrated) found in southern China's provinces of Jiangxi, Fujian, Guangdong, and Yunnan. These deposits account for the large majority of global heavy rare earth supply. Outside China, the most significant source of heavy rare earths is Myanmar — specifically the Kachin region in northern Myanmar, where Chinese-backed mining operations have expanded rapidly since 2020. Myanmar's output flows almost entirely to Chinese processors.

The supply chain beyond the mine is entirely Chinese. Dysprosium oxide is separated, refined, and processed into metal and alloy forms by Chinese facilities that have no equivalent outside China at commercial scale. Lynas Rare Earths — the only significant rare earth producer operating outside China at scale — produces primarily light rare earths (neodymium and praseodymium) and does not produce meaningful quantities of heavy rare earths including dysprosium. There is no non-Chinese dysprosium processing infrastructure of consequence anywhere in the world.

China's April 2025 export licence regime added a formal control layer on top of this structural dominance. Export licences are now required for dysprosium oxide, dysprosium metal, and dysprosium-containing alloys. Every cross-border shipment requires Beijing's approval. The regime created an immediate and persistent price split between domestic Chinese prices and ex-China prices, which now carry an access premium that has not unwound. The November 2026 export control review is the next scheduled decision point.

Myanmar adds a second supply risk that runs underneath the Chinese one. The Kachin region operations supplying Chinese processors operate in territory with unstable governance and periodic disruptions. When Myanmar ore supply is interrupted, Chinese heavy rare earth processing volumes tighten, and global dysprosium availability tightens with them.

Why It Matters Right Now

The demand case is structural and compounding from multiple directions simultaneously. Every NdFeB magnet used in a high-performance application — EV traction motors, wind turbine generators, industrial servo motors, defense actuators — requires dysprosium to function at operating temperature. EV production is growing globally. Wind turbine installations are accelerating. Defense procurement of electric drive systems, drone motors, and missile guidance components is increasing. All of these applications draw on the same approximately 2,000-tonne-per-year global supply.

The substitution constraint is real but partial. Magnet manufacturers have worked for years on dysprosium reduction — using grain boundary diffusion (a manufacturing technique that concentrates dysprosium at the boundaries between magnetic grains rather than distributing it throughout the entire magnet, reducing the total quantity needed without reducing coercivity performance) and alternative heavy rare earth additions including terbium. These techniques have reduced dysprosium intensity per magnet meaningfully but have not eliminated the requirement. For high-temperature applications — traction motors in EVs, direct-drive wind turbines — dysprosium remains necessary.

The 2026 price move answers that question plainly. Dysprosium oxide domestic China opened 2026 at approximately $86 per kilogram and has risen approximately 105% year to date to $177.30 per kilogram. The November 2026 export control review is the immediate forward catalyst. If China extends or tightens the export licence regime, the access premium above domestic prices widens further and Western buyers face tighter supply.

Solving Neodymium Doesn't Solve the Magnet

Here is the gap that most supply chain analysis misses: the Western policy effort to build rare earth independence has focused almost entirely on the wrong rare earth for the most critical application.

Neodymium has multiple supply sources in active development. Lynas produces it in Australia and Malaysia. MP Materials produces it in California. Energy Fuels is building separation capacity in Utah. Western governments have directed hundreds of millions of dollars toward neodymium supply chain development. The policy community has at least partially understood the neodymium problem and responded with real investment.

Dysprosium has almost none of this. There is no Western dysprosium producer. There is no Western dysprosium processing facility. There is no credible near-term project outside China scheduled to produce meaningful dysprosium supply within this decade. The same NdFeB magnets that Western supply chain policy is trying to source from non-Chinese neodymium supply chains still require dysprosium — and that dysprosium still comes entirely from Chinese supply chains.

The supply chain independence effort for permanent magnets is structurally incomplete. It addresses the light rare earth input. It leaves the heavy rare earth input entirely dependent on China. A magnet manufactured at MP Materials' Mountain Pass facility using non-Chinese neodymium still requires Chinese dysprosium to function at motor operating temperature. The Western magnet is only as independent as its most constrained input. And the most constrained input has received the least attention.

This is not a minor gap in policy design. It is the gap that makes the entire permanent magnet supply chain independence effort conditional on continued Chinese cooperation — regardless of how much is invested in neodymium.

What the Price Has Done

Dysprosium oxide domestic China traded in the $200–350 per kilogram range through most of 2022–2023, reflecting post-COVID supply chain normalisation and relatively stable Chinese separation output. Prices compressed lower through 2024 as the broader rare earth complex experienced oversupply pressure from Chinese producers expanding output into a softer global market.

By the start of 2026, dysprosium oxide domestic China had fallen to approximately $86 per kilogram — near multi-year lows. The compressed price reflected Chinese domestic oversupply, modest near-term demand growth, and no immediate policy catalyst.

China's April 2025 export licence announcement changed the trajectory. The regime — covering dysprosium alongside neodymium, terbium, and other rare earth elements — added friction to every cross-border shipment and created immediate price pressure as Western buyers began pricing in access risk on future supply. The export licence premium above domestic prices emerged and persisted.

The 2026 rally accelerated from multiple simultaneous inputs: the export licence regime constraining Western access, MIIT quota limits on Chinese rare earth separation capacity tightening domestic output, and accelerating EV and wind turbine demand pulling on the same thin supply base. By March 2026, the SMM domestic price had reached $191.08 per kilogram — more than doubling from the January open in under three months.

May 2026: the SMM domestic benchmark sits at $177.30 per kilogram — a modest pullback from the March peak, but still up approximately 105% year to date. FOB China averages approximately $292 per kilogram. Western retail stands at approximately $930.70 per kilogram. The three-tier price structure tells the access story precisely: domestic China ($177.30/kg) is the price Chinese magnet manufacturers pay; FOB China ($292/kg) is what a Western industrial buyer pays after securing an export licence — the approximately $115 difference is the export licence access premium in concrete terms.
