China Locks Down Rare-Earth Technology as Lynas Moves Into Malaysian Magnet Plant: Global NdFeB Supply Chain Accelerates Restructuring

The global rare-earth supply chain is entering a new phase of competition. China's Ministry of Commerce previously announced export controls on rare-earth-related technologies, covering not only mining, smelting and separation, and metal smelting, but also magnet manufacturing and rare-earth secondary resource recovery technologies. Notably, "magnet manufacturing" explicitly includes samarium-cobalt, NdFeB, and cerium magnet production technologies.

The key significance of this control is not limiting the export of a single rare-earth product, but extending the scope of control to process know-how. According to the announcement, the controlled technologies and their carriers include design drawings, process specifications, process parameters, processing procedures, and simulation data; technologies for the assembly, commissioning, maintenance, repair, and upgrading of related production lines are also brought under management.

In other words, China is not only in control of rare-earth raw materials but is also seeking to safeguard its core capabilities spanning rare-earth separation through high-performance magnet manufacturing. For overseas companies, replicating a complete NdFeB magnet production line outside China could become more difficult in terms of obtaining equipment, talent, parameters, and process support.

Even as China tightens its technology controls, the non-China rare-earth supply chain is also accelerating its own build-out. Australian rare-earth company Lynas Rare Earths announced on July 7 that it has signed a long-term cooperation agreement with South Korea's JS Link to build a rare-earth permanent magnet plant in Kuantan, Malaysia. The plant is planned to produce 3,000 tons of sintered NdFeB permanent magnets annually. Lynas will invest approximately AUD 50 million and supply rare-earth materials to JS Link's magnet plants in South Korea and Malaysia, with an exclusive supply arrangement extending through January 2038.

Lynas stated that magnets produced at the Malaysian plant will serve the automotive, wind power, and electronics manufacturing supply chains. This indicates that the non-China rare-earth supply chain, which previously focused on mining, separation, and oxide supply, is now extending further into metal and magnet manufacturing.

From an industry perspective, both pieces of news actually point to the same trend: rare-earth competition is no longer just about "who has the mines," but "who can master the complete process." China is consolidating its technological advantage through export controls, while overseas companies are building alternative capacity through investment and cooperation. In the short term, China's advantage in rare-earth separation and high-performance NdFeB magnet manufacturing remains difficult to shake; but over the medium to long term, cooperative projects in Malaysia, South Korea, Australia, and elsewhere could gradually reshape the bargaining structure of the global magnet materials supply chain.

For the automotive, wind power, robotics, consumer electronics, and high-efficiency motor industries, this supply chain restructuring is worth close attention. Future risks in rare-earth magnetic materials may stem not only from price volatility, but also from technology licensing, export permits, the pace of capacity build-out, and end-use compliance requirements.

Key Observations:

• China's rare-earth controls have expanded from raw materials to magnet manufacturing technology.
• NdFeB process parameters, drawings, and processing procedures may become sensitive items.
• The Lynas–JS Link magnet plant in Malaysia represents the non-China supply chain extending downstream into magnet manufacturing.
• The focus of global rare-earth competition is shifting from "resource access" to "technology, capacity, and compliance capability."
