A civilian-use license lets Beijing meter yttrium one buyer at a time

The instrument is a license condition. Chinese exporters have to prove the yttrium will be used for civilian purposes only, and that rule stayed in force when China agreed to defer tougher restrictions on rare earths and magnets for a year ^[3]. Approval therefore lands per shipment and per buyer. Reuters, in a report summarised by mezha.net, says that granularity is what lets Beijing meter supply for a particular country or a particular company, and that exports fell again after the October meeting ^[4].

Yttrium is not formally a rare earth element, but it almost always occurs with them, so it is handled in the same industrial and regulatory context ^[19].

The volumes released since the stoppages are small. The March consignment was 60 tonnes of yttrium oxide ^[6]; another 29 tonnes went to the US in July, after exports had stayed suspended through the spring ^[7]. Together that is 89 tonnes ^[21]. The US Geological Survey put world production last year between 10,000 and 15,000 metric tons, and China does not publish data on its mining and separation quotas for the metal ^[10], so the two shipments come to roughly 0.6 to 0.9 percent of one year's estimated global output ^[22].

What the metal does explains where the damage landed first. Yttrium goes into displays, semiconductors and lasers, and its most important application is thermal barrier coatings for jet engines, which let parts survive extremely high temperatures ^[12]. The account names aircraft engine and semiconductor production as the sectors hit hardest by the shortage ^[13], while the stopped production it documents is in the coating supply chain alone ^[24]. Extending that to wafer fabs goes past what the evidence carries.

Japan shows how selective the license can be. Tokyo has received almost no yttrium since November 2025, when Prime Minister Sanae Takaichi angered Beijing with statements about defending Taiwan ^[15]. Gallium, terbium and dysprosium were restricted at the same time ^[16]. Japan has been through this: Beijing curbed rare earth exports after the 2010 dispute over islands in the East China Sea, and Tokyo has since diversified suppliers and built stockpiles while remaining heavily dependent on China ^[17]. Several Japanese companies have warned in filings to the Tokyo Stock Exchange about the effects of the current restrictions ^[18].

US Trade Representative Jamieson Greer said he was concerned about the slow pace of Chinese yttrium exports, and that Washington sometimes has to remind Beijing directly of its requirements ^[9]. After a leaders' meeting in May, China said it was ready to work with the US on rare earth supply questions it called justified ^[8].
