Japan’s yttrium squeeze puts alternative sourcing and refining plans in focus

This is a retrospective of the supply-chain report dated 12 November, not a new restriction announced that day. Taiwan’s International Trade Administration, citing Nikkei, described pressure on Japan’s yttrium supply and prices and efforts to source outside China. It mentioned the risk of inventories running out, not confirmation that all yttrium-consuming factories had stopped or that shortages were universal.

Yttrium is used in LEDs and coatings on semiconductor-manufacturing equipment components. The report cites Argus Media’s September 2026 European price of US$1,087 per kilogram, up ninefold year on year in its wording. This is a month- and market-specific comparison, not a live 12 November transaction price or every Japanese company’s delivered cost.

Japanese customs data use another basis. According to the report, September import unit values for yttrium oxide rose 64-fold year on year, while January–September import volumes fell about 70% to 294 tonnes. Rising unit values and lower cumulative volumes describe procurement pressure, but import values are not European market quotes and nine-month quantities are not monthly demand.

The policy background includes China’s April 2025 controls on seven rare earths and tighter restrictions on Japan in January 2026. Japan’s response includes US cooperation, G7 information-sharing and diversification of mining and refining. The report lists expanded sourcing from the US, South Korea, Germany, Türkiye and Estonia. It does not guarantee a new supply quantity from each country.

At company level, capacitor makers were looking at alternative sources. Shin-Etsu Chemical planned at least ¥35 billion for a Fukui plant capable of refining 16 rare earths including yttrium, while Mitsui Kinzoku still faced difficulty obtaining enough Chinese material. Planned refining capacity is not material already available for delivery. The story concerns several adjustments, not a supplier that has eliminated the risk.
