China Cuts Off Yttrium: US Gas Turbines Left Without Supply

What Happened?

China has shut off the yttrium tap. According to foreign trade data and reports from Xataka, in May 2026 China exported not a single gram of yttrium to the United States. Restrictions began in April 2025, when Beijing imposed export controls on several rare earths in retaliation for US technology sanctions. They resumed in trickles in October 2025 and saw a one-time peak in March 2026, but since then the flow has been completely cut off. Despite talks between Trump and Xi Jinping in which China pledged to review restrictions, the reality is that the commitment did not translate into sustained shipments. In fact, according to consultancy Volt Rush, yttrium oxide exports to the US fell to zero in May 2026, an unprecedented event since records began.

Why Is This Important?

Yttrium is a critical component of thermal barrier coatings that protect gas turbine blades and jet engines. Without that coating, blades would melt at operating temperatures exceeding 1,500°C. Companies like GE Vernova, one of the world's largest gas turbine manufacturers, depend entirely on this material. Unlike other rare earths such as neodymium, which already have alternative supply chains in Australia (Lynas), Canada (Mountain Pass), or Europe (Norra Kärr mine in Sweden), yttrium lacks a consolidated source outside China. China controls approximately 95% of global refined yttrium production, according to US Geological Survey (USGS) data. This makes the dependency structural rather than temporary. The only mine outside China that produces yttrium as a byproduct is Mount Weld in Australia, but its refining capacity is limited and cannot replace Chinese volumes in the short term.

What Consequences Will It Have?

The consequences are severe for the US energy and defense industries. Gas turbines are essential for electricity generation, especially at a time when power demand is growing due to artificial intelligence and electrification (data center demand is expected to rise 30% by 2030). Without yttrium, turbine production and maintenance grind to a halt. Jet engines are also affected, impacting commercial and military aviation. For example, GE9X engines powering the Boeing 777X use yttrium in their coatings. In the short term, there is no substitute: alternative materials like gadolinium zirconate are not yet ready for large-scale production. The only option is to accelerate mining and refining in other countries, but that will take years. US company MP Materials has announced plans to produce yttrium at its Mountain Pass plant, but significant volumes are not expected until 2028. Meanwhile, turbine manufacturers' yttrium inventories could run out in less than six months, according to industry estimates.

Moreover, this restriction comes amid rising geopolitical tensions. China has previously used rare earth controls as a trade weapon: in 2010 it reduced exports during the dispute with Japan over the Senkaku Islands, and in 2019 it threatened to cut off supply to the US during the trade war. However, yttrium was a blind spot in Western diversification strategy. Now a critical vulnerability in the Western supply chain is exposed. The economic impact could be enormous: gas turbines account for 35% of US electricity generation, and a maintenance halt could cause blackouts and raise electricity prices.

What Should Readers Know?

That China's rare earth dependency is not limited to magnets for electric vehicles. Yttrium is an example of how a little-known material can have a disproportionate impact. Readers should closely follow diversification efforts and investments in mining outside China, as well as potential US government responses such as the Defense Production Act or subsidies for domestic refining. It is also important to understand that although alternatives are in development (like gadolinium zirconate or recycled yttrium), none are ready to replace yttrium in the short term. Recycling yttrium from discarded turbines could cover up to 10% of demand, but requires infrastructure that does not yet exist. In the defense sector, the Pentagon is already evaluating alternative coatings for F-35 fighter engines, but trials will not conclude until 2027. Meanwhile, dependence on Chinese yttrium remains total, and the tap closure is a wake-up call for the West to accelerate its own rare earth supply chains.
