Non-China NdFeB capacity is expanding rapidly, but bottlenecks lie in metals/alloys and cost competitiveness

Overview

This report summarizes a discussion between Morgan Stanley and an expert with about 35 years of experience in the rare earth permanent magnet industry. The discussion focused on non-China magnet capacity expansion, lower rare earth usage, China-related supply risks, rare earth substitution risks, and the impact on demand for NdPr, Dy, and Tb. The core conclusion is that non-China NdFeB capacity is being built, especially in the U.S., where planned capacity is already sufficient relative to current imports, but converting nameplate capacity into effective output remains constrained by metal/alloy supply, manufacturing yields, customer certification, and cost competitiveness.

Core views

The report believes NdFeB still has a strong price-performance advantage, with limited risk of broad substitution. NdPr is more structural in the magnet chemistry system, while Ce/La substitutes are more likely to fill the low-cost, low-performance segment rather than replace high-performance NdFeB. The intensity of Dy/Tb use is declining more noticeably, and in some applications heavy rare earth demand has been reduced by more than 50% through grain boundary diffusion, grain boundary engineering, grain refinement, and lower operating temperatures. China's export controls and national security considerations are pushing OEMs to seek non-China sources, but commercialization still needs to solve cost and quality-system issues.

Analysis framework

The report uses an expert interview / conference note format, combining the expert's views on capacity projects, supply-chain links, technical substitution, end-market demand, and policy risks with current import volumes, application scenarios, and the industry rating framework to form a qualitative analysis of supply and demand in the rare earth permanent magnet value chain and its investment implications.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• MP MATERIALS CORP

  The report mentions it as one of the covered companies tied to U.S. NdFeB capacity expansion.

  Strengths

  Benefits from U.S. rare earth supply-chain localization, non-China magnet capacity buildout, and OEM diversification of sourcing.

  Weaknesses

  Capacity utilization depends on customer certification, metal/alloy supply, yields, process control, and cost competitiveness.

  Comparison

  Compared with Chinese suppliers, Western producers may close the quality gap more quickly, but they are unlikely to match China's low-cost base in the short term.

  Risks

  Project execution, cost premium, certification delays, export-control compliance, and weaker-than-expected end-market demand.

• NdPr

  The core rare earth input for high-performance NdFeB magnets.

  Strengths

  Substitution is relatively difficult, and total rare earth content has only fallen slightly over the past two decades, supporting resilient demand.

  Weaknesses

  Ce/La low-cost grades can siphon demand in some performance ranges.

  Comparison

  Compared with Dy/Tb, NdPr has less room for intensity reduction.

  Risks

  Changes in end-use motor technology and the shift of low-performance applications to ferrites or other magnet types.

• Dy/Tb

  Heavy rare earths used to improve the performance of high-temperature and high-performance NdFeB magnets.

  Strengths

  Still used in high-temperature, aerospace, defense, and demanding applications.

  Weaknesses

  Grain boundary diffusion and design optimization have significantly reduced unit usage.

  Comparison

  Compared with NdPr, Dy/Tb use intensity has fallen more noticeably, and demand has been reduced by more than 50% in some applications.

  Risks

  Ongoing technological effort to reduce usage may make demand less elastic than end-market output growth.

• NdFeB permanent magnets

  The core product discussed in the report, used in EVs, wind power, industrial applications, robotics, and defense.

  Strengths

  Strong price-performance advantage, and the expert does not expect broad substitution.

  Weaknesses

  Western capacity faces constraints in cost, automation, quality systems, and customer certification.

  Comparison

  Ferrites, alnico, and iron-nitride magnets are suitable for specific scenarios but cannot fully replace high-performance NdFeB.

  Risks

  Low-price competition from China, supply-chain bottlenecks, export controls, and changes in end-demand structure.

Key data

• U.S. NdFeB capacity in 2028Approximately 28 ktpaBased on announced projects and expansion by mature U.S. manufacturers; if funded and potential projects are included, broader capacity is about 35 ktpa.
• Current U.S. bulk magnet importsApproximately 8.5 ktpaSources include China, Vietnam, and Europe; if projects are executed successfully, announced capacity should theoretically cover current usage.
• Potential U.S. capacity after 2028Approximately 50-55 ktpaThis is the expert's estimate of longer-term expansion potential.
• Non-China capacity in Europe and JapanEurope approximately 3.6 ktpa, Japan approximately 6.8 ktpa+Based on expansion by existing producers and the current capacity base.
• Change in total rare earth content in NdFeBAbout 32% down to about 30.5%The expert said total rare earth content has only declined slightly over the past two decades, indicating limited room for NdPr substitution.
• Decline in heavy rare earth demandMore than 50% in some applicationsMainly achieved by reducing Dy/Tb usage through grain boundary diffusion, grain boundary engineering, grain refinement, and design changes.
• Time from construction to full production for mature companiesAbout 3 yearsFrom plant design to full production; startups may need close to 6 years.
• U.S. domestic NdFeB cost premiumAbout 50% higherThe expert estimates that magnets made in the U.S. may be about 50% more expensive than those sourced from China.
• Defense NdFeB demandPossibly less than 500 tpaThe scale is small, but overlap with commercial and industrial applications may complicate approvals.
• EV magnet usageAbout 12 g/kW, and slightly above 2 kg/vehicle for a battery electric light vehicleHybrid vehicles use about half as much magnet material as battery electric light vehicles.

Impact & implications

For investors, the expansion of non-China rare earth magnet supply chains increases the strategic importance of upstream and midstream assets such as MP Materials, but short-term attention should not be focused only on nameplate capacity. What really determines profitability and market share is metal/alloy supply, yields, quality systems, customer certification speed, and the cost curve. NdPr demand is more resilient, while Dy/Tb demand faces greater pressure from declining intensity; China's export controls raise the supply-chain security premium while also increasing commercial approval and compliance uncertainty.

Risks

• Non-China projects underperform, so nameplate capacity cannot be converted into effective output.
• Insufficient oxide-to-metal conversion and strip-cast alloy supply limit magnet manufacturing ramp-up.
• Western magnet costs are significantly higher than Chinese supply, which may suppress customer adoption and margins.
• Customer certification, quality systems, yields, and process control progress more slowly than expected.
• China's export controls and dual-use approvals increase uncertainty in commercial transactions.
• Demand growth for NdFeB in end markets such as wind power, EVs, or robotics is weaker than expected, or is diverted to other motor or magnet technologies.

What to watch

• Construction progress, yields, and customer certification milestones for U.S. NdFeB capacity projects through 2028.
• Metal/alloy supply capacity of non-China producers such as MP Materials, e-VAC / VacuumSchmelze, and Noveon Magnetics.
• China's rare earth export control policies, commercial approval pace, and changes in OEM purchasing behavior.
• Price trends for NdPr, Dy, and Tb, and the pace of further reductions in heavy rare earth unit usage.
• Real demand for high-performance magnets from EVs, wind power, mobile robotics, and aerospace/defense.
• Whether the quality gap and cost gap between Western magnets and Chinese magnets narrow.
