Japan’s manufacturers can currently secure only about two-thirds of required rare-earth supply after Chinese dysprosium and terbium exports fell to zero in the first half of 2026. The disruption is accelerating a global push to build processing and magnet capacity outside China.

Japan’s rare-earth supply chain has moved from diversification planning to an immediate industrial constraint.
Chinese exports of dysprosium and terbium products to Japan fell to zero in the first half of 2026, according to trade data cited by Caixin Global. An analysis by pricing agency Argus estimates that Japanese manufacturers are securing only around two-thirds of the rare-earth material they need.
The shortage is expected to persist until at least 2027, as alternative projects backed by Japan’s Organization for Metals and Energy Security, or JOGMEC, require another one to two years to reach meaningful production.
The immediate impact is concentrated in heavy rare earths, which are used in high-temperature neodymium-iron-boron magnets. Dysprosium and terbium help magnets maintain performance under heat and stress, making them important inputs for electric-vehicle motors, wind turbines, robotics, aerospace systems and defense equipment.
Japan’s predicament also exposes a wider weakness in the critical minerals supply chain 2026: adding mine capacity is not enough if manufacturers cannot secure separated oxides that meet technical specifications.
A shortage that reaches beyond Japan
Japan has been working for years to reduce its dependence on Chinese rare-earth processing. The country has supported projects in Australia, Europe and Southeast Asia, while Japanese companies have pursued stockpiles and long-term supply agreements.
Those efforts have not yet matched the speed of the disruption.
Japan imported only about 13 tonnes of dysprosium in the first half of 2026, an 82% decline from the same period in 2024, according to market data summarized by industry researchers. Imports were reported at zero in several months, including January, February, May and June.
The problem is not limited to dysprosium and terbium. Erbium prices have risen by more than 50% since early June in some markets, as buyers assess the risk of further restrictions and seek to build inventories. Erbium has applications in fiber-optic systems and other communications technologies, adding an artificial-intelligence and data-networking dimension to the rare-earth squeeze.
At the same time, neodymium-praseodymium, or NdPr, has moved in the opposite direction. NdPr oxide prices have slipped below US$110 per kilogram, according to market reports, after reaching approximately US$125/kg in February. The retreat has removed some speculative heat from the market, but prices remain above pre-restriction levels.
That distinction matters. The rare-earth market is not experiencing one uniform shock. Heavy rare earths are facing a physical availability problem, while NdPr is experiencing a more complicated combination of elevated prices, changing inventories and uncertainty over future demand.
Qualification testing is becoming as important as mine development in non-Chinese rare-earth supply chains.
The strategic gap between a project and a product
The shortage is forcing manufacturers to focus on a question that has often been secondary in mining announcements: can a project consistently deliver qualified material to an end user?
A rare-earth deposit may contain dysprosium, terbium or NdPr, but that does not mean it can produce separated oxides at commercial scale. Between the resource and the magnet factory are multiple stages:
- Mining and beneficiation
- Concentrate or mixed-carbonate production
- Chemical separation
- Oxide purification
- Metal and alloy conversion
- Magnet manufacturing and customer qualification
China’s advantage has historically been built across this entire chain. Many competing projects outside China have developed only one or two stages, leaving them dependent on third-party processors, uncertain feedstock or untested downstream markets.
Japan’s supply gap is therefore increasing the value of processing capacity and customer qualification. A project that can produce a magnet-ready oxide may be strategically more useful than a larger resource that still requires an unbuilt separation plant.
Non-Chinese projects move into the spotlight
The United States and its allies are responding with a combination of public finance, industrial policy and private-sector processing initiatives.
The U.S. International Development Finance Corporation has committed $62.8 million to rare-earth projects in Malawi, Angola, Madagascar and South Africa, according to the Reuters report published by Kitco.
Approximately $50 million is directed toward the Phalaborwa project in South Africa, where Rainbow Rare Earths plans to recover rare earths from gypsum waste generated by an earlier chemical operation. The project is designed to produce NdPr as well as dysprosium and terbium. Construction is expected to begin in 2027, with production targeted for 2028.
Other DFC-backed initiatives include support for Pensana’s Longonjo project in Angola and early-stage work in Madagascar. None of the African projects included in the Reuters report had reached commercial production at the time of publication.
The funding highlights both the strategic importance of African supply and the difficulty of financing it. DFC executives told Reuters that private investors remain reluctant to fund rare-earth projects because of political, technical and pricing risks. Market intervention by China can also undermine project economics, particularly for NdPr-focused developments.
| Supply-chain node | 2026 milestone | Strategic relevance | Main risk |
|---|---|---|---|
| Japan | Chinese Dy and Tb exports to Japan fell to zero in H1 | Immediate demand for qualified alternatives | Supply gap through at least 2027 |
| South Africa | About $50 million in DFC support for Phalaborwa | Potential future NdPr, Dy and Tb source | Construction and commercial ramp-up |
| United States | Energy Fuels’ Tb oxide qualified by a major Japanese magnet maker | Demonstrates customer acceptance of non-Chinese material | Commercial-scale production remains ahead |
| Canada | Ucore produced 99.5%+ NdPr oxide at its Kingston demonstration plant | Adds separation capacity within an allied supply chain | Scale-up, feedstock and customer qualification |
| Global NdPr market | Prices reported below US$110/kg after a February peak near US$125/kg | Indicates easing from peak conditions, not a return to old pricing | Volatility and demand uncertainty |
Energy Fuels: qualification before scale
Energy Fuels is one of the clearest examples of how a processor can gain strategic relevance before reaching full heavy-rare-earth production.
The company has reported that terbium oxide produced at its White Mesa Mill in Utah has passed qualification testing for commercial use by a major Japanese rare-earth permanent-magnet manufacturer. The product joins NdPr and dysprosium materials that the company says have also undergone customer qualification.
The milestone is significant because qualification is a critical commercial hurdle. A manufacturer’s approval indicates that the material meets its specifications for a defined application. It does not, however, guarantee a binding offtake agreement, a specific sales volume or profitability.
Energy Fuels is developing heavy-rare-earth separation capacity at White Mesa, with commercial-scale terbium and dysprosium circuits targeted for completion around the end of 2027. The company has outlined planned annual capacity of approximately 20 tonnes of terbium oxide and 120 tonnes of dysprosium oxide, alongside additional samarium, europium and gadolinium capacity.
For Japanese buyers, the value is not simply the location of the plant. It is the combination of a non-Chinese source, an existing processing site and a product that has passed customer testing.
For investors, Energy Fuels is therefore an execution-sensitive case rather than a straightforward beneficiary of higher rare-earth prices. The key indicators are construction progress, feedstock availability, recovery rates, customer volumes and the timing of commercial output.
Ucore: Canada tests the separation link
Ucore is addressing a different part of the supply chain.
The company has reported producing commercial-grade NdPr oxide with purity above 99.5% at its RapidSX demonstration plant in Kingston, Ontario. The facility has processed material from different feedstocks, including ionic-clay-derived mixed rare-earth oxide and North American bastnaesite-derived carbonate.
Ucore has shipped qualification samples to major rare-earth magnet manufacturers. Its demonstration work is intended to show that the RapidSX process can separate rare-earth material in Canada using a modular system with a smaller footprint than conventional solvent-extraction plants.
The company’s progress illustrates why separation technology is attracting government support. Mining projects can be located in one country, feedstock can originate in another and magnet production can occur elsewhere. A Canadian separation facility could serve as an intermediate node linking North American and allied resources to manufacturers.
The commercial test remains scale. Producing a high-purity sample is not the same as operating a profitable, continuous refinery. Ucore will need to demonstrate consistent throughput, secure suitable feedstock and complete customer qualification at larger volumes.
Canadian separation capacity is intended to connect diverse allied feedstocks with downstream magnet manufacturers.
Africa adds resources, but not immediate relief
African projects could become important to the longer-term critical-minerals map, particularly where they produce heavy rare earths or use waste-recovery models.
Phalaborwa is notable because it does not depend on a conventional greenfield mine. Its feedstock is stored gypsum waste, potentially reducing some mining and beneficiation requirements. The project still faces processing, financing and construction risks, but its planned dysprosium and terbium production aligns directly with the materials Japan is struggling to secure.
Pensana’s Longonjo project in Angola offers another model: an African resource connected to transport infrastructure and intended to supply Western downstream processing. The Lobito Corridor could help move material to export markets, although logistics, construction and financing remain central questions.
These projects will not solve Japan’s shortfall in the next several months. Their significance is strategic and medium-term. If they reach production, they could expand the number of jurisdictions supplying magnet materials and reduce reliance on a single processing center.
What the market is pricing: and what it is not
The current rare-earth market is rewarding scarcity, but it is also testing whether scarcity can be converted into reliable production.
The strongest position belongs to projects that can demonstrate four things:
- A relevant product mix: Dysprosium and terbium exposure is particularly valuable during the current Japanese shortage.
- Qualified material: Customer testing and approval matter more than a preliminary resource estimate.
- Secured feedstock: Processing plants need consistent material, whether from an owned mine, a waste stream or contracted suppliers.
- Visible construction progress: Financing announcements must eventually translate into equipment installation, commissioning and commercial output.
The retreat in NdPr prices below US$110/kg reinforces the need for discipline. A project built around peak prices may struggle if the market normalizes before it reaches production. Conversely, a flexible processor with access to heavy rare earths may benefit from premiums that remain elevated even if NdPr softens.
Japan’s zero-export shock has therefore changed the competitive map, but it has not removed execution risk. Energy Fuels, Ucore and African developers are pursuing different pieces of the solution. Their progress should be assessed through production milestones, qualification results and contract quality: not simply through exposure to the rare-earth theme.
The broader lesson for the critical minerals supply chain 2026 is clear: control of the mine is only the beginning. The strategic advantage will belong to companies and countries that can connect geology, separation chemistry, customer qualification and manufacturing into a dependable chain.
Shareable takeaway: Japan’s heavy rare-earth shortage is no longer a distant geopolitical risk. With Chinese dysprosium and terbium exports at zero in the first half of 2026, manufacturers are seeking qualified supply from the United States, Canada and Africa: but commercial scale remains the decisive test.
