China Restricted Yttrium Exports to U.S. Markets
Aerospace manufacturers are adopting material substitutes and recycling efforts to mitigate ongoing supply chain reliance.

Should the U.S. prioritize domestic production over cheaper foreign imports for critical industrial materials?
China imposed export controls on yttrium shipments in 2025, leaving the United States with total import reliance for the material. The supply shift forced U.S. aerospace manufacturers to accelerate the testing of alternative coating materials and enhance recycling processes for turbine blade components.
Why it matters
The controls created significant cost and supply volatility for manufacturers requiring heat-resistant coatings on jet engine blades. This dependence remains a critical vulnerability as the U.S. seeks to bolster domestic processing capacity at facilities like the Mountain Pass, California, site.
China supplied 70% of U.S. yttrium imports between 2021 and 2024, while the U.S. remained 67% import reliant for rare-earth metals overall in 2025. A $150 million federal loan was issued to support a domestic heavy-rare-earth separation facility at Mountain Pass, California.
The players
GE Vernova
An American multinational energy company providing power generation technology and aerospace components.
Oerlikon
A global engineering group specializing in surface technologies and advanced materials for manufacturing.
The details
Manufacturers are currently testing zirconium-dioxide coatings stabilized with magnesium or calcium to replace traditional yttria-stabilized options in turbine blades. Large operators like GE Vernova have managed supply disruptions by increasing inventory stocks, though these reserves have limited lifespans. Companies are also attempting to recover and recycle coating material directly from manufacturing processes to reduce dependence on imported feedstock.
Timeline
China supplied 70% of U.S. yttrium imports between 2021 and 2024.
The United States remained 100% import reliant for yttrium in 2025.
Reported Chinese yttrium shipments plunged in February 2026.
Oerlikon reported creative sourcing for yttrium oxide in April 2026.
GE Vernova inventory was expected to last until 2026.
Market Landscape
The U.S. remains heavily reliant on Chinese rare-earth processing, which accounts for 87% of global capacity. This situation reflects a broader trend of supply chain decoupling as firms look to replace key materials like yttrium that are subject to restrictive export licensing.
Operators in aerospace and heavy industry should review their reliance on rare-earth-based coatings and evaluate the lead times for substitute materials. Securing diverse supply chains or investing in material recovery processes is now essential to mitigate the risk of sudden export licensing changes.
The takeaway
The restriction on rare-earth exports underscores the urgency of diversifying material sources beyond single-nation suppliers. Business owners should audit their current inventory of rare-earth compounds and verify if suppliers have successfully tested non-yttrium alternatives for high-heat applications.
