China's Fluorite Prices Stable Amid Tight Supply and Cautious Demand

[SMM Aluminum News Flash] This week, China's 97% fluorite powder delivery-to-factory prices remained stable, with the mainstream transaction range at 3,300-3,550 yuan/mt, and notable regional price spreads. In terms of supply, safety inspections in China's major producing areas continued to tighten, compounded by the impact of earlier safety incidents, resulting in tight market supply circulation and an overall rigid contraction pattern. Demand side, downstream hydrofluoric acid enterprises saw profit margins squeezed by high-priced sulphuric acid, and most enterprises primarily restocked on an as-needed basis, with limited willingness to chase higher prices in bulk. Overall, SMM expects the fluorite market to maintain a fluctuating trend in the short term.
