TSMC Said to Seek Rare-Earth-Free Motors for Its Chip Fabs

TSMC is exploring alternatives to rare-earth components in its factory equipment, three people familiar with the matter told Reuters, which reported the move on 22 October 2026. Reuters says the aim is “to reduce the risk that Beijing’s export controls could disrupt operations at plants that make the world’s most advanced chips.”

According to three industry executives briefed by the company, TSMC “has surveyed suppliers on using rare-earth-free motors in factory-automation equipment.” Reuters reports that the talks are at an early stage. TSMC did not immediately respond to Reuters’ request for comment.

A short Business Engineer explainer on the chips at the heart of AI. It teaches the general idea only and says nothing about any company, government or person in this piece.

What Was Reported

Reuters, in a story by Wen-Yee Lee and Fanny Potkin, says the move is “reported for the first time”. One of the people told Reuters that the effort was driven by concerns about potential supply disruptions from China.

Two of the people said the discussions “have not yet resulted in a broad rollout of rare-earth-free equipment”. Reuters does not name the suppliers TSMC surveyed or say which tools would change first.

The background, as Reuters puts it, is that China “last year put certain rare-earth materials, magnets and related processing technology under export controls, requiring licences.”

What Was Posted on X

Reuters’ post on 22 October carries the headline of its exclusive: ‘TSMC seeks factory-equipment alternatives to thwart China’s rare earths grip, sources say’. It is the report this piece is built on; the article attributes the move to three people familiar with the matter, and TSMC had not commented.

Why Rare Earths Matter to a Chip Factory

Rare earths are a group of metals used to make very strong permanent magnets. Reuters explains the link: “Rare-earth magnets are commonly used in motors that power moving parts in industrial equipment, including machinery found in highly automated factories such as those operated by TSMC.”

Reuters says a shortage of such parts “could disrupt chip production for customers in smartphone, AI system, data centre and defence supply chains.” As we read it, the exposure sits in the machines that move wafers around the plant, not in the chips themselves.

What Washington and Taipei Have Said

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

Taiwan’s Economy Minister Kung Ming-hsin said in February that the government would support the Industrial Technology Research Institute (ITRI) to develop rare-earth technologies, Reuters reports, with plans for a pilot production line “within three years that could meet an estimated 50% of the island’s domestic demand.”

In a statement to Reuters, ITRI said it was working with the Department of Industrial Technology at Taiwan’s Ministry of Economic Affairs to plan a rare-earth project. A person at a US-based think tank told Reuters that US officials have engaged ITRI in talks about diversifying critical-mineral supply chains.

The Structural Read

As we read it, the move is defensive and early: two of Reuters’ sources say the talks “have not yet resulted in a broad rollout of rare-earth-free equipment”, and one says it was driven by concerns about potential supply disruptions from China.

As we read it, governments are working the supply side while TSMC works the demand side: Reuters reports Taiwan’s plan for an ITRI pilot line “within three years that could meet an estimated 50% of the island’s domestic demand.”

As we read it, the people most exposed are TSMC’s customers: Reuters says a shortage “could disrupt chip production for customers in smartphone, AI system, data centre and defence supply chains.”

Three Implications

FOR CHIP BUYERS As we read it, factory equipment joins substrates and test capacity on the list of supply points worth asking a foundry about; Reuters does not say any TSMC customer has been affected.

FOR EQUIPMENT MAKERS Reuters reports that TSMC surveyed suppliers on rare-earth-free motors for factory-automation equipment, which, as we read it, makes motor design a selling point for tool vendors.

FOR READERS OF SUPPLY-CHAIN NEWS As we read it, the report rests on unnamed people and TSMC has not commented, so the next confirmation would be a TSMC statement or a supplier announcement.

The Business Engineer Lens

This story maps onto the Business Engineer framework AI’s Geopolitical Chokepoint.

The framework argues that “The digital economy rests on a physical foundation that most people in that economy never see.”

As we read it, the motors that move wafers around a fab are part of that foundation. The framework was published in December 2025 and does not discuss TSMC’s survey of suppliers.

What Is Not Established

The report rests on people familiar with the matter and on executives briefed by TSMC. TSMC has not commented. Reuters does not give a cost, a timeline, the share of TSMC’s tools that use rare-earth motors, or the names of the suppliers asked. Nothing in the report says TSMC has faced a shortage.

Connecting the Coverage

On 19 October we reported that China’s Ministry of Commerce issued five export-control announcements in four days, in our piece on China’s new export curbs. The same day, our minerals piece reported that, on U.S. Geological Survey figures, the U.S. import share of rare-earth compounds and metals rose from 53% to 67% between 2024 and 2025.

On 21 October, in our piece on Nvidia’s supplier advances, Nvidia disclosed a $1.1 billion advance to test supplier KYEC. Today our Samsung substrates piece covered Maeil’s report of about $2.8 billion from Tesla and Nvidia for Samsung Electro-Mechanics. What’s new here is the world’s largest contract chipmaker reportedly working on the factory-equipment side of the same supply chain.

The Bottom Line

TSMC has surveyed suppliers on rare-earth-free motors for its factory-automation equipment, Reuters reports, citing three people. The work is early and TSMC has not commented. As we read it, the AI chip supply chain now has a risk point in the motors inside the fab, alongside the substrates and test capacity buyers are already paying ahead for.
