Global supplies of yttrium, a rare earth element critical to aerospace, energy, and semiconductor production, are running dangerously low due to Chinese export restrictions, Reuters reports. China, the dominant supplier of yttrium, imposed controls in April on seven rare earths, including yttrium, in retaliation for U.S. tariffs. These restrictions require exporters to obtain licenses from Beijing, creating bottlenecks and delays for international buyers. While some measures have been temporarily paused, the April restrictions remain in effect, leaving industries worldwide uncertain about future access.
The limits have triggered a scramble for yttrium, pushing European prices for yttrium oxide, used in heat-shield coatings, up 4,400% since January to $270 per kilogram. Chinese prices, by contrast, remain far lower, around $7 per kilogram, though they have risen 16% since the start of the year. Analysts warn that shortages could become a major chokepoint for critical sectors. The Aerospace Industries Association emphasized that advanced jet engines depend heavily on imported yttrium, and the semiconductor industry uses it as a protective coating and insulator, with shortages rated “9 out of 10” in severity by industry sources.
While companies like Mitsubishi Heavy and Siemens Energy report that current operations have not been directly affected, they are actively seeking alternatives to reduce dependence on Chinese supply. U.S. business jet maker Gulfstream Aerospace also said its exposure remains limited, though broader shortages could increase production times, costs, and equipment inefficiency for larger manufacturers.
The United States currently imports nearly all of its yttrium from China, with 93% sourced directly and the remainder derived from material first processed in China, according to the U.S. Geological Survey. Domestic alternatives are emerging: ReElement Technologies in Indiana plans to begin producing 200 tons of yttrium oxide per year by December, increasing to 400 tons by March. This could partially alleviate reliance on Chinese exports, which halted U.S. shipments after April and declined by about 30% globally.
Industry sources report that stocks outside China vary widely, with estimates ranging from one to 12 months of consumption. Some traders have already exhausted their inventories, and the opaque nature of the market makes it difficult to predict when or if supply pressures will ease. Analysts warn that without a comprehensive U.S.-China trade resolution or new domestic production, shortages of yttrium could continue to drive costs higher and strain global supply chains for years to come.
