Scandium is one of the scarcest metals, with global production of only about 40 tonnes per year. Its crustal abundance is not extraordinarily low, but the root cause of its chronic shortage is that there are almost no economically viable standalone mines — it is recovered only as a byproduct of refining other metals. Layer China's 2025 export controls on top of that, and scandium oxide prices roughly tripled, while SOFC and aerospace demand keeps climbing. For procurement, scandium is a material carrying a double constraint at once: scarcity and regulation.
Why It Is So Scarce: The Byproduct Recovery Structure
Scandium's scarcity comes not from reserves but from how it is recovered. Scandium rarely occurs concentrated in a specific ore, so there are almost no deposits worth mining on their own. Instead it is recovered as a byproduct of the following processes.
- Titanium refining: residues from titanium ore processing
- Rare earth refining: byproduct of rare earth separation
- Uranium refining: byproduct of uranium recovery
The fundamental constraint this creates is that scandium supply is subordinate to the output of the host metals (titanium, rare earths, uranium). Even if scandium demand rises, recovery cannot be independently scaled up unless host-metal production also rises. That structural reason is why global output stays around 40 tonnes a year.
Supply Concentration and Alternative Sources
Supply of refined scandium oxide (Sc₂O₃) is significantly concentrated in China. That concentration is what amplified the impact of the 2025 export controls. Alternative sources are being developed but remain at an early stage.
| Source | Status |
|---|---|
| China | Significant concentration of refined Sc₂O₃ supply |
| Australia | Alternative source in development, early commercialization |
| Philippines | Alternative source in development, early commercialization |
| Canada | Alternative source in development, early commercialization |
If projects in Australia, the Philippines, and Canada reach commercial production, supply diversification will advance, but as of July 2026 they are not a near-term fix. In procurement practice, running a China licensing track in parallel with non-China tracks is the realistic approach.
Demand: SOFCs and Aerospace Alloys
Two axes drive scandium demand: fuel cells and aerospace materials.
- SOFC electrolyte (ScSZ): scandium-stabilized zirconia is a high-performance electrolyte for solid oxide fuel cells. The representative composition, 10Sc1CeSZ, contains about 11% scandium oxide. Growth in the solid oxide fuel cell market is directly linked to scandium demand.
- Al-Sc alloys (aerospace): adding a small amount of scandium to aluminum improves strength, weldability, and corrosion resistance, making it useful in aerospace structural materials.
With demand structurally rising while supply is locked to byproduct recovery, price and lead-time volatility is high.
After Export Controls Compounded It in 2025
When China's MOFCOM Announcement No. 18 added scandium to the export control list in April 2025, a regulatory constraint was added to an already scarce material. Scandium oxide prices rose roughly threefold, from about $1,200/kg before the controls to $3,500–4,370/kg after. Because the controls are a case-by-case licensing regime rather than an embargo, procurement is possible with documented civilian use and dual sourcing. The impact on the SOFC supply chain and the response strategy are covered in detail in How China's scandium export controls reshaped the SOFC supply chain.
The overall structure and timeline of the controls are in China materials export control timeline, and procurement strategy under a licensing regime is laid out in Procurement strategy in the age of export controls.
Frequently Asked Questions
Why is scandium so scarce?
Not because of crustal abundance but because of how it is recovered. With almost no economically viable standalone mines, it is recovered only as a byproduct of titanium, rare earth, and uranium refining, which makes supply subordinate to host-metal production. Global output is only about 40 tonnes a year.
What is scandium used for?
Two main uses: SOFC electrolytes (scandium-stabilized zirconia, ScSZ) and aerospace aluminum-scandium alloys. Demand is directly linked to growth in the solid oxide fuel cell market.
Are there alternative sources outside China?
Alternative sources are being developed in Australia, the Philippines, and Canada, but they are at an early commercialization stage. In the near term, running a China licensing track in parallel with non-China tracks is the practical response.
How much did prices rise after the export controls?
Scandium oxide prices rose roughly threefold, from about $1,200/kg before the controls to $3,500–4,370/kg after.
