Firmennachrichten über Borax Prices Climb 8.7% in September 2026 as Import Supply Tightens
Chinese borax prices moved sharply higher in September 2026, diverging from a broadly weaker domestic chemical market. The SunSirs benchmark price for borax rose from RMB 5,960 per tonne on 1 September to RMB 6,480 per tonne on 22 September — a gain of 8.7% in three weeks. The benchmark for borax pentahydrate reached RMB 5,800 per tonne on 21 September, up 2.96% from the RMB 5,633.33 per tonne recorded at the start of the month.
The move is unusual because it runs against the direction of the wider sector. Chinese commodity monitoring data for early September showed the majority of monitored chemical products declining, with sulfuric acid down approximately 3.6%, phosphate fertilizer down approximately 2.5%, and caustic soda down approximately 0.4%. Borax was one of the few products to post a material gain.
