China Rare Earth Industry Association Advances November Forum to Strengthen Semiconductor Materials Supply Chain

Highlights

• China Rare Earth Industry Association will host a Polishing Materials and Precision Processing Technology Forum in Kunming on November 12, targeting semiconductor and optical applications.
• Cerium oxide used in semiconductor polishing slurries represents a strategic chokepoint, with high-purity processing expertise mattering more than raw deposit ownership.
• The 'qualification trap' means alternative suppliers could emerge in mining before semiconductor makers finish qualifying replacement polishing materials.
• Western suppliers may find competitive opportunity in purification, particle engineering, and slurry formulation rather than competing in commodity rare earth oxides.
• REEx recommends monitoring semiconductor-grade cerium oxide capacity and slurry qualification milestones as better indicators of supply security than oxide volumes alone.
