TSMC Seeks Rare-Earth Alternatives Amid China Supply Risks

Taiwan Semiconductor Manufacturing Company (TSMC), the world’s largest contract chipmaker, is exploring alternatives to rare-earth components used in its factory equipment as concerns grow over China’s control of critical mineral supplies. The initiative aims to reduce the risk that Chinese export restrictions could disrupt highly automated semiconductor manufacturing operations, according to three people familiar with the matter.

The discussions, reported for the first time by Reuters on October 22, 2026, highlight a growing vulnerability in the global semiconductor supply chain. China has imposed export controls on certain rare-earth materials, magnets and related processing technologies, requiring licences for affected exports. Any shortage of specialised components could threaten manufacturing operations that supply advanced chips for smartphones, artificial intelligence (AI) systems, data centres and defence applications.

TSMC has reportedly surveyed equipment suppliers about the possibility of using motors that do not depend on rare-earth materials in factory automation systems. However, the initiative remains at an early stage, and the company has not yet introduced a broad rollout of rare-earth-free equipment.

Why TSMC Is Looking Beyond China’s Rare Earth Supplies

Rare-earth elements are important inputs for a wide range of modern technologies, including electric motors, industrial machinery, renewable energy equipment and electronics. Although these elements are not necessarily rare in the Earth’s crust, extracting and processing them economically can be difficult. Developing alternative sources and manufacturing processes also takes time, investment and specialised expertise.

China occupies a dominant position in several stages of the global rare-earth supply chain, particularly processing and the production of certain permanent magnets. This concentration creates a potential risk for manufacturers worldwide when export restrictions, licensing requirements or other supply disruptions affect the availability of critical materials.

For TSMC, the concern is not limited to the materials used directly in semiconductor manufacturing. Rare-earth components can also be embedded in the industrial equipment that keeps production facilities operating.

Rare-earth magnets are commonly used in motors that power moving components in industrial machinery. In highly automated semiconductor factories, these motors can form part of systems responsible for moving equipment, handling materials and supporting manufacturing processes.

If specialised motors or their components become difficult to obtain, replacing them may not be as simple as purchasing a different product. Alternative components could require engineering changes, compatibility checks, reliability testing and qualification before they can be used in a semiconductor production environment.

TSMC’s reported supplier survey therefore represents an effort to identify possible alternatives before a supply disruption occurs. The objective is to reduce exposure to a potential bottleneck rather than wait for export restrictions to affect production.

TSMC Surveys Suppliers on Rare-Earth-Free Motors

According to three industry executives briefed by TSMC on its plans, the Taiwanese company has asked suppliers to examine the use of rare-earth-free motors in factory automation equipment. One person familiar with the effort said concerns about possible supply disruptions from China were driving the initiative.

The discussions remain preliminary. Two people familiar with the matter said they had not resulted in a broad deployment of equipment that completely avoids rare-earth materials.

This distinction is important because exploring a technology is not the same as validating it for large-scale industrial use. Semiconductor manufacturing facilities operate under demanding requirements for precision, reliability and consistent performance. Any replacement component must satisfy the technical needs of the equipment in which it will be installed.

Suppliers may also need to evaluate whether alternative motors can deliver the required performance throughout extended operating periods. Depending on the application, the transition could involve redesigning components, adjusting control systems and checking whether existing equipment can accommodate the new technology.

TSMC had not immediately responded to a request for comment at the time of the Reuters report. The company had not publicly confirmed a timetable for adopting rare-earth-free motors or disclosed how many pieces of equipment might eventually be affected.

The reported initiative should therefore be viewed as an early supply-chain risk-reduction effort, rather than evidence that TSMC is already replacing all rare-earth-dependent equipment in its factories.

How China’s Rare Earth Export Controls Could Affect Semiconductor Manufacturing

China’s export controls have increased international attention on the concentration of critical mineral supply chains. Licensing requirements can introduce additional uncertainty for companies that rely on affected materials, especially when they have limited alternative suppliers or need components manufactured to specific technical standards.

For semiconductor manufacturers, the consequences of a disruption could extend beyond the immediate cost of a material. A shortage of one specialised component can create problems for equipment maintenance, replacement schedules and the availability of spare parts.

Semiconductor production involves interconnected processes, with sophisticated equipment operating in carefully controlled environments. If a necessary component becomes unavailable and no qualified substitute exists, manufacturers could face delays in maintenance or equipment installation. The actual impact would depend on inventory levels, supplier arrangements, the affected component and the time required to identify an alternative.

TSMC supplies chips used across several major technology industries. Its customers and their downstream partners depend on reliable manufacturing capacity for products ranging from consumer electronics to AI infrastructure. This makes the resilience of the company’s equipment supply chain an issue with implications beyond Taiwan.

Demand for advanced computing has also increased the strategic importance of semiconductor manufacturing. AI accelerators, data-centre processors and other high-performance chips rely on complex production processes and specialised manufacturing equipment. Disruptions at a major supplier could create challenges for companies that depend on a steady flow of components.

However, China’s rare-earth export controls do not automatically mean that semiconductor production will be interrupted. The practical effects depend on which materials and products are covered, whether licences are granted, the availability of inventories and whether manufacturers can source alternatives.

United States and Taiwan Work to Diversify Critical Mineral Supply Chains

TSMC’s reported effort comes as the United States and Taiwan have publicly discussed reducing their dependence on Chinese rare-earth and critical-mineral supply chains.

In June, Raymond F. Greene, director of the American Institute in Taiwan, said the United States was working with Taiwan and other partners to develop alternative supply sources, expand processing capacity and build more resilient supply chains.

The American Institute in Taiwan performs many of the functions associated with a US diplomatic mission in Taiwan, where formal diplomatic arrangements differ from those in many other countries. Greene’s comments reflected a broader effort to address vulnerabilities in supply chains that support advanced technology and industrial production.

Developing alternative supplies involves more than identifying new mineral deposits. Companies and governments must also consider processing facilities, specialised manufacturing, environmental requirements, investment costs and the time needed to establish commercially viable operations.

For rare-earth materials, expanding processing and magnet production capacity can be particularly important. A country may have access to mineral resources but still depend on overseas facilities to refine them or manufacture the specialised components required by industrial customers.

Building a more diversified supply chain could give manufacturers additional sourcing options if trade restrictions or geopolitical tensions affect existing suppliers. Nevertheless, replacing an established supply network is a gradual process that may require sustained investment and cooperation between governments, researchers and private companies.

Taiwan Plans Domestic Rare Earth Technology Development

Taiwan has also been exploring ways to strengthen its domestic capabilities in rare-earth technologies. In February, Taiwan Economy Minister Kung Ming-hsin said the government would support the Industrial Technology Research Institute (ITRI), a domestic research organisation, in developing relevant technologies.

The plan included establishing a pilot production line within three years. According to Kung’s remarks, the proposed line could meet an estimated 50% of Taiwan’s domestic demand.

The figure represents a stated target for the proposed project, not confirmation that Taiwan currently produces half of its rare-earth requirements domestically. Achieving that level would depend on the project’s development, technical performance, production capacity and the definition of the domestic demand being measured.

ITRI’s work could contribute to Taiwan’s efforts to develop local expertise and reduce reliance on external suppliers. Research and pilot production may help establish the technical processes needed before any expansion into commercial-scale manufacturing.

In a statement, ITRI said it was working with the Department of Industrial Technology at Taiwan’s Ministry of Economic Affairs to plan a rare-earth project. The institute did not provide further details in response to the Reuters report.

The proposed initiative is part of a wider effort to strengthen Taiwan’s technological and industrial resilience. While the island is a critical centre for advanced semiconductor manufacturing, the equipment and materials supporting that industry come from complex international supply networks.

US Officials Show Interest in Taiwan’s Rare Earth Research

The United States has also shown interest in ITRI’s work. According to a person at a US-based think tank familiar with the discussions, American officials have held talks with the institute about diversifying critical-mineral supply chains.

The engagement suggests that Taiwan’s research capabilities could be relevant to a broader effort to develop alternatives to concentrated supply networks. However, the available information does not establish whether the discussions have resulted in a formal agreement, a joint production programme or a specific commitment to purchase materials from the proposed facility.

The US State Department did not immediately respond to a request for comment at the time of the report.

Cooperation between the United States and Taiwan could potentially support research, processing technologies and the development of alternative components. But the commercial success of any project would depend on whether it can deliver reliable products at competitive costs and in sufficient quantities.

For companies such as TSMC, the availability of alternative materials is only one part of the challenge. They must also ensure that replacement components can be integrated into existing manufacturing systems without compromising reliability or production quality.

Why Rare-Earth-Free Equipment Could Matter for TSMC

Reducing dependence on rare-earth materials in selected equipment could provide TSMC with an additional layer of protection against supply disruptions. If viable alternatives become available, the company and its suppliers may be able to diversify procurement and reduce the consequences of export restrictions affecting particular components.

Such a strategy could offer several potential advantages:

• Lower exposure to supply shocks: Alternative motor designs could reduce dependence on components linked to a concentrated supply chain.
• More flexible sourcing: Suppliers may gain additional options when purchasing materials or manufacturing replacement components.
• Improved maintenance planning: Qualified alternatives could help reduce the risk that a shortage of a specialised part delays repairs or equipment replacement.
• Greater supply-chain resilience: Diversifying critical inputs can help manufacturers prepare for geopolitical tensions, licensing delays and unexpected shortages.
• Better long-term planning: Early research gives equipment makers time to assess alternatives before a disruption becomes an immediate operational problem.

These benefits are potential outcomes, not guaranteed results. Rare-earth-free motors may have different performance characteristics, costs or design requirements. Some applications may be easier to adapt than others, and certain specialised equipment could continue to require rare-earth components.

Consequently, the most practical approach may involve selective substitution rather than the complete elimination of rare-earth materials from every part of a semiconductor factory.

Challenges in Replacing Rare-Earth Components

Developing alternatives to rare-earth magnets can be technically demanding because these materials offer properties that make them valuable in compact, high-performance motors. An alternative design must provide the necessary combination of power, efficiency, durability and operating characteristics for its intended application.

Different industrial systems also have different requirements. A motor suitable for one type of factory automation equipment may not be appropriate for another. Manufacturers therefore need to assess alternatives at the component and application levels instead of assuming that a single replacement will work across an entire facility.

Cost is another consideration. Even if an alternative design performs adequately, manufacturers must determine whether it can be produced consistently and economically. Changes to equipment may also require new testing procedures, supplier approvals and adjustments to maintenance practices.

For semiconductor facilities, reliability is especially important. Equipment changes must be evaluated carefully because failures or unexpected performance variations can affect operations. The transition to alternative components may therefore take time, even when a technically promising option has been identified.

There is also a broader supply-chain question: replacing a rare-earth component does not necessarily eliminate every dependency on China. Alternative motors may still rely on other materials, subcomponents or processing stages sourced from concentrated markets. A comprehensive resilience strategy would need to consider these indirect dependencies as well.

What TSMC’s Move Means for the Global Chip Industry

TSMC’s reported supplier discussions illustrate how geopolitical risks are increasingly influencing decisions about industrial equipment and manufacturing inputs. For years, semiconductor supply-chain debates have focused heavily on chipmaking capacity, advanced manufacturing technology and access to specialised production tools. Critical minerals and components used inside those tools are now receiving greater attention.

The distinction matters because semiconductor production depends on an extensive network of suppliers. A chip factory requires not only sophisticated manufacturing machines but also motors, electronic components, materials, spare parts and maintenance support. Vulnerabilities in any critical part of that network can become operational concerns.

Other manufacturers may also review their exposure to concentrated sources of critical materials, although the Reuters report does not establish that all semiconductor companies are pursuing the same strategy as TSMC.

For governments, the issue highlights the difficulty of building resilient supply chains in industries that depend on specialised materials and internationally integrated manufacturing. Diversification may require research funding, new processing facilities, commercial partnerships and a willingness to pay for additional supply options.

For equipment suppliers, the development could create demand for new motor designs and alternative materials. However, any wider commercial opportunity will depend on performance, price, manufacturing capacity and the ability to meet the strict requirements of semiconductor production.

For TSMC, the immediate question is whether early-stage discussions can eventually produce technically qualified alternatives that reduce exposure to potential supply interruptions without compromising factory performance.

What Happens Next?

The next steps will likely depend on technical assessments by TSMC and its equipment suppliers, the availability of viable alternative motor designs and progress on Taiwan’s rare-earth technology initiatives. The company has not announced a broad deployment plan, a completion date or a quantified target for reducing its use of rare-earth components.

Several developments will be important to watch:

• Supplier testing: Whether equipment manufacturers can demonstrate that rare-earth-free motors meet the requirements of relevant factory automation systems.
• Equipment qualification: Whether alternative designs can pass the reliability and performance checks required for semiconductor manufacturing environments.
• Taiwan’s pilot project: Whether ITRI advances its proposed rare-earth technology programme and establishes the planned pilot production line within the stated three-year period.
• Supply-chain partnerships: Whether Taiwan, the United States and other partners announce concrete measures to expand alternative sources and processing capacity.
• Export-control developments: Whether changes to China’s licensing requirements affect the availability of rare-earth materials, magnets or related technologies.

Until further details are announced, it remains unclear how quickly TSMC could adopt alternative components or how much of its equipment would be suitable for conversion. The reported discussions nevertheless indicate that the company is assessing supply risks before they become an immediate threat to manufacturing operations.
