Indium Supply Chain: Producers and Processing
Facts checked against sources on . How we check facts.
Indium is recovered mostly from the zinc ore mineral sphalerite, and indium tin oxide coatings on flat-panel displays account for most of its consumption. In 2025 China produced an estimated 760 t, 69% of world refinery production (USGS world total: 1,100 t), according to the US Geological Survey (USGS). US net import reliance for indium in 2025 was 100%. Indium is on the US, Australian and Canadian critical minerals lists.

How is indium traded and what limits supply?
- February 2025. China's Ministry of Commerce subjected several critical minerals, including indium, to new export restrictions. Asian Metal reported that exports of unwrought indium fell 72% year over year from September 2024 to September 2025.
- 2025. Fifth-generation (5G) technologies continued to increase demand for indium. USGS expects artificial intelligence to raise demand for specialized chip materials, including those made from indium phosphide.

Export controls and trade measures
- China has required export licenses for indium since 2025 (USGS Table 4).
Resources. The indium content of the zinc deposits from which it is recovered ranges from less than 1 part per million to 100 parts per million. It also occurs in trace amounts in chalcopyrite and stannite, but recovery from most of those deposits is not economic.
Frequently asked questions
Which country produces the most indium?
China produces the most indium: an estimated 760 t, or 69% of the world total, in 2025, according to the USGS refinery production figures.
What is indium used for?
Indium is used in indium tin oxide (ITO) coatings, alloys, solders and compounds and electrical components and semiconductors. Indium tin oxide (ITO) coatings: most global consumption; electrically conductive thin films in flat-panel displays, most commonly liquid crystal displays.
Is indium a critical mineral?
Yes. Indium is on the US, Australian and Canadian critical minerals lists. Indium was already on the 2022 US list and stays on the final 2025 list of 60 minerals. US net import reliance for indium in 2025 was 100%.
Can indium be recycled?
Indium is most commonly recovered from ITO scrap in Japan and the Republic of Korea. Indium-containing scrap is recycled in the United States, but USGS has no data on the quantity.
