China's Antimony Ingot Output Surges 30% MoM in July 2026, SMM Assessment Reveals

SMM assessment shows that China’s antimony ingot output (including antimony ingots, converted crude antimony, cathode antimony, etc.) in September 2026 fell by approximately 2% month-on-month, continuing its downward trend. Regarding the drop in September antimony output, some market participants view it as a normal development. After all, according to customs data, the sharp decline in overseas antimony ore imports in August will inevitably translate into lower antimony ingot production.

5N Plus plans to expand its St. George, Utah facility by approximately 50%, with completion targeted for H2 2027. The site transforms indium antimonide and other specialty materials into semiconductor materials, wafers, substrates and selected components, with recovery, purification and crystal-growth capabilities. New equipment will be installed progressively, but InSb-specific capacity was not disclosed; the 50% figure refers to the facility expansion, not indium demand.
