Global supply chains for critical materials are facing renewed pressure as China’s exports of dysprosium and terbium fell sharply in early 2026, underscoring the country’s continued dominance in the rare earth elements market and its ability to influence global availability through targeted export controls. Trade data shows a severe contraction in shipments, pointing to a rapid tightening in some of the most strategically important materials used in modern industry.
Exports of dysprosium dropped by nearly 75% year-on-year in January, falling to approximately 6,200 kilograms, before effectively halting in February. At the same time, terbium exports also declined sharply, falling by 35% in January and plunging by up to 87% year-on-year in February. The steep reductions highlight how quickly supply conditions can change when export restrictions are applied to niche but critical materials.
The downturn follows China’s introduction of export licensing controls in 2025, which placed several heavy rare earth elements under tighter regulatory oversight. While overall rare earth exports have remained relatively stable, the measures have been applied selectively, with dysprosium and terbium among the most heavily impacted materials. This targeted approach has allowed China to maintain broad export flows while restricting specific strategic inputs.
Why Dysprosium and Terbium Matter for Global Industry
Dysprosium and terbium play a crucial role in the production of high-performance permanent magnets, which are essential for:
- Electric vehicle motors
- Wind turbine generators
- Advanced defense systems
- High-temperature industrial applications
Their unique properties allow magnets to maintain performance under extreme heat and stress, and there are currently no cost-effective substitutes at scale, making supply disruptions particularly impactful.
Market Tightening and Rising Procurement Pressure
The sharp decline in exports is already reshaping global market conditions. Manufacturers are reporting:
- Tighter material availability
- Higher procurement costs
- Increased reliance on inventories
- Greater use of long-term supply contracts
These trends highlight the fragility of global industries that depend on a highly concentrated rare earth supply base. China’s influence is not limited to mining. The country also controls the majority of global rare earth processing capacity, allowing it to regulate supply more precisely across individual materials. This integrated structure enables Beijing to adjust export flows selectively without significantly disrupting overall trade volumes, reinforcing its position as the central hub of the global rare earth supply chain.
Global Efforts to Diversify Supply Are Accelerating
In response to growing supply risks, efforts to build alternative supply chains are intensifying. Key developments include:
- New rare earth mining projects in North America and allied markets
- Expansion of processing capacity outside China
- Increased investment in recycling technologies
- Research into material efficiency and reduced rare earth usage in magnets
However, these initiatives remain in early stages and have yet to materially offset China’s dominant position.
Structural Constraints Limit Short-Term Response
Despite rising investment, the development of independent supply chains for heavy rare earths remains slow due to:
- High capital requirements
- Complex processing technologies
- Long project development timelines
- Limited existing infrastructure outside China
As a result, global markets remain highly exposed to supply disruptions in the near term.
A Structural Shift in the Rare Earth Market
The steep decline in dysprosium and terbium exports represents more than a temporary fluctuation. It signals a structural tightening in the most sensitive segment of the rare earth market, with broad implications for:
- Clean energy technologies
- Electric vehicle production
- Advanced manufacturing
- Defense and strategic industries
