TSMC Seeks Rare-Earth-Free Factory Equipment as China’s Export Controls Threaten Chip Supply Chains

Taiwan Semiconductor Manufacturing Co. (TSMC) is exploring alternatives to rare-earth components used in its factory equipment as concerns grow that China's export restrictions could disrupt production of the advanced semiconductors powering artificial intelligence, smartphones, data centers and defense systems.

The world's largest contract chipmaker has surveyed suppliers about replacing motors containing rare-earth materials with alternatives in factory-automation equipment, three industry executives briefed on the company's plans told Reuters. The initiative, reported for the first time, is driven partly by concerns that Beijing's restrictions could interrupt supplies of specialized components required to keep highly automated semiconductor plants running.

The discussions remain at an early stage and have not yet resulted in a broad deployment of rare-earth-free equipment, two people familiar with the matter said. TSMC declined to comment.

The initiative underpins a less visible vulnerability in the global semiconductor industry. While attention often centers on access to advanced chipmaking technology, manufacturing capacity also depends on a complex network of industrial components and materials that can be difficult to replace quickly.

Rare-earth magnets are used in motors that power moving parts in industrial machinery, including equipment deployed in automated factories. A shortage of specialized motors or related components could create maintenance problems, delay equipment installations, or disrupt production if manufacturers cannot secure suitable replacements.

Such risks for TSMC come with implications that go far beyond Taiwan. The company manufactures advanced chips used across the global technology industry, including processors supporting AI systems and data-center infrastructure. Any prolonged interruption to its operations could affect customers that depend on reliable supplies of high-performance semiconductors.

China's position in rare-earth supply chains has therefore become a potential source of operational risk for semiconductor manufacturers, even when the materials in question are not direct ingredients in the chips themselves.

Beijing last year placed certain rare-earth materials, magnets and related processing technologies under export controls, requiring licenses for covered exports. The measures have increased concerns among manufacturers that depend on specialized components sourced through Chinese supply chains.

Rare earths are a group of 17 metallic elements used in a range of industrial applications, including permanent magnets, electric motors, electronics and defense equipment. Their importance comes not simply from their availability in the Earth's crust but from the difficulty of developing competitive alternatives and establishing the processing capacity needed to produce materials at scale.

For semiconductor manufacturers, the concern is the potential for disruption at a point where replacement options may be limited. Chip fabrication plants operate with tightly controlled processes and expensive equipment that must maintain high levels of reliability. A component shortage can become a production risk if equipment cannot be repaired, replaced, or commissioned on schedule.

TSMC's supplier survey suggests the company is assessing that risk before a disruption occurs. Investigating rare-earth-free motors could give the chipmaker more options if export licensing delays or supply restrictions make existing components harder to obtain.

However, replacing rare-earth-based components in industrial equipment is not necessarily straightforward. Alternative motor designs must meet the performance, precision, reliability, and operating requirements of semiconductor manufacturing. Suppliers may also need to qualify new equipment and demonstrate that it can function consistently in demanding production environments.

The early stage of TSMC's discussions indicates that reducing dependence on rare-earth components is likely to be a gradual engineering and supply-chain exercise rather than an immediate switch.

The episode also demonstrates how export controls can influence industrial decisions even before they produce a confirmed shortage. The possibility that critical components may become harder to obtain can encourage manufacturers to diversify suppliers, redesign equipment, and hold additional inventories, potentially increasing costs across the supply chain.

Taiwan and The US Pursue Alternative Supply Chains

TSMC's initiative comes as Taiwan and the United States seek to reduce their reliance on Chinese sources of rare earths and other critical minerals.

In June, Raymond F. Greene, director of the American Institute in Taiwan, Washington's de facto embassy on the island, said the United States was working with Taiwan and other partners to develop alternative sources of supply, expand processing capacity and strengthen supply-chain resilience.

Taiwan has also outlined plans to develop domestic rare-earth capabilities. In February, Economy Minister Kung Ming-hsin said the government would support the Industrial Technology Research Institute (ITRI), a domestic research organization, in developing rare-earth technologies.

The plan envisages establishing a pilot production line within three years that could meet an estimated 50% of Taiwan's domestic demand, according to Kung. The target points to an effort to build local capabilities, although a pilot line would not by itself establish that Taiwan could replace Chinese supplies across all rare-earth materials and industrial applications.

ITRI said it was working with the Department of Industrial Technology at Taiwan's Ministry of Economic Affairs to plan a rare-earth project but provided no further details.

US officials have also shown interest in ITRI's work and held discussions with the institute on diversifying critical-mineral supply chains, according to a person at a US-based think tank familiar with the talks. The US State Department did not immediately respond to a request for comment.

These efforts reflect the growing overlap between industrial policy and technology security. Governments are increasingly concerned that concentrated control over materials and processing capabilities could give suppliers leverage over industries considered economically or strategically important.

The challenge impacts Taiwan significantly because its semiconductor industry depends on uninterrupted access to specialized equipment, components, and materials from international suppliers. Developing domestic alternatives could reduce exposure to external supply shocks, but establishing viable production capacity requires investment, technical expertise and time.

The United States faces a similar challenge in trying to diversify supply chains while maintaining access to materials needed for electronics, advanced manufacturing and defense. Building alternative sources involves more than identifying new mines; processing, refining, magnet production, and qualification of finished components must also be developed.

Nevertheless, TSMC's exploration of rare-earth-free equipment shows that the semiconductor supply chain extends well beyond the fabrication process itself. The industry's resilience is based on access to the motors, machinery, materials, and specialized parts that allow chipmaking facilities to operate continuously.

The risk is not that China's export controls have already halted TSMC's production. The reported supplier discussions instead indicate that the company is examining potential vulnerabilities and evaluating alternatives before any disruption materializes.

Replacing components across a semiconductor factory can be costly and technically demanding. This means manufacturers must weigh the expense of redesigning equipment against the potential consequences of relying on suppliers exposed to geopolitical restrictions.

The broader challenge, however, lies in the ability of Taiwan and its international partners to build alternative supply chains quickly enough to reduce concentrated dependencies without creating new bottlenecks or substantially increasing manufacturing costs.
