On the supply side, a Jiangsu producer ramped up high-purity anhydrous potassium carbonate capacity to 50,000 tonnes per year, according to ChemPriceHub on 2026-08-08. The development adds domestic capacity for the high-purity grade within China, where the quoted price is assessed.
The weekly and monthly declines of 0.5% and 0.4% indicate a gradual easing through late September, following the softer trajectory recorded since the July level of USD 1,135/tonne. The current quotation remains within the 52-week range set by the June peak and the November trough, and the year-on-year gain of 0.8% keeps the annual comparison positive despite the quarter's decline of 2.1%.
