Rare earths are often discussed as a mining story, but the bigger vulnerability sits further down the supply chain. China accounted for about 85% of global rare-earth refining in 2025 and 94% of permanent-magnet production in 2024. Those magnets are essential components in electric vehicles, wind turbines, industrial motors and electronics, leaving manufacturers exposed when exports require licences or shipments are delayed.
China’s April 2025 controls on several heavy rare earths and related products showed how quickly that exposure can reach factory floors. Export volumes fell, and some automakers reduced production or temporarily paused operations while seeking supplies. The measures are licensing requirements rather than a blanket ban, but licensing delays and uncertainty can still disrupt production and raise costs.
A broader set of controls announced in October 2025—including measures affecting additional rare earths, processing technologies and some products made outside China—has been suspended through November 10, 2026. The existing April controls remain in effect. For manufacturers, that distinction matters: a temporary suspension can ease immediate pressure, while reliance on a concentrated supply chain continues.
The Bottleneck Is Beyond The Mine
New mines outside China can diversify where raw materials come from, but they do not automatically create independent supply chains. Rare earths must be separated, refined, converted into metals and alloys, and made into high-performance magnets. These steps require specialised technology, skilled workers, equipment and customers willing to support new facilities as they scale.
The project pipeline remains uneven. Based on projects announced by early 2026, planned refining capacity outside the dominant supplier is equivalent to roughly two-thirds of expected mine output by 2035. Planned magnet production is only about one-third of that mining capacity. If the downstream stages lag, manufacturers may continue depending on the same processing hubs even as more ore is mined elsewhere.
What Manufacturers And Investors Should Watch
Manufacturers can reduce exposure by mapping suppliers beyond the first tier, checking whether components rely on controlled materials or technologies, and building sourcing options for magnets and processed rare earths. Recycling and material substitution may help in some applications, but neither is an instant replacement for established production at scale.
For investors, a mine announcement is only one part of the picture. Processing capability, magnet production, customer contracts, financing and the ability to bring facilities into operation all affect whether a project can contribute to supply. Policy support may help new capacity, but timing and execution remain central to assessing its commercial prospects.
MarketMind Insight
Rare-earth supply risk is concentrated in the stages that turn mined material into usable components. Export controls make that concentration visible to manufacturers through licensing delays and production interruptions, while investors should distinguish between projects that add ore and those that expand refining or magnet capacity. Diversification is advancing, but until those downstream stages catch up, supply resilience will remain a work in progress.
