Production Cost Trend: The Calcium Sulfate Production Cost Trend saw a mild increase due to higher energy prices and logistics costs, impacting overall production economics.
Demand Outlook: The Calcium Sulfate Demand Outlook for Q4 2025 is positive, with expected growth in residential and commercial construction. The Calcium Sulfate Price Forecast indicates potential moderate price increases if construction activity remains strong.
For the Quarter Ending June 2025 Asia-Pacific
The Calcium Sulphate Price Index in China increased by approximately 1.9% in June 2025, with the upward trend likely continuing into July. The price increase in July 2025 can be attributed to sustained demand from infrastructure-led construction and water treatment sectors.
The Calcium Sulphate Spot Price rose to USD 107/ton FOB Shanghai in June, following modest gains in April and May, reflecting a gradual but firm recovery in public infrastructure activity.
The Calcium Sulphate Demand Outlook remained strong in July, bolstered by ongoing public construction projects, including rail and factory infrastructure. Construction PMI reached 52.8, supporting the positive demand sentiment.
Municipal and industrial water treatment applications also maintained steady demand, driven by environmental upgrades and increased usage in descaling and flocculation processes.
The Calcium Sulphate Production Cost Trend remained stable as high operating rates, improved energy availability, and cost-optimized raw material sourcing helped balance elevated inventory drawdowns from earlier months.
Strategic stockpiling by buyers ahead of policy-driven infrastructure rollouts in Q3 further fueled upward pricing momentum in July.
Europe
The Calcium Sulphate Price Index in Germany remained fluctuating throughout Q2 2025, reflecting instability in regional construction recovery and variations in industrial demand.
The price trend in July 2025 is expected to have shown moderate stabilization or slight increase, supported by seasonal demand from building material producers and a steady water treatment market.
The Calcium Sulphate Spot Price movement was volatile due to inconsistent offtake from the construction sector, influenced by EU funding delays and real estate caution.
The Calcium Sulphate Demand Outlook in July remained dependent on public infrastructure and localized industrial consumption, though broader construction activity still lacked consistent momentum.

Product Description
Calcium sulphate (CaSO₄)—occurring as gypsum (dihydrate), hemihydrate (plaster of Paris) and anhydrite—is produced industrially by mining and beneficiation of natural gypsum followed by controlled calcination (kettle or rotary calciner at ~120–160 °C for β hemihydrate, autoclave for α hemihydrate; higher temperatures for anhydrite), and synthetically as FGD gypsum from flue gas desulfurization (limestone–gypsum process), as a by product in phosphoric acid (“phosphogypsum,” with restricted uses due to impurities) and from neutralizing sulfuric acid with limestone or calcium carbonate in various organic acid processes. Key downstream (consumer) industries include building materials (drywall/gypsum board, plasters, joint compounds, cement set regulator), construction chemicals, ceramics and mold making, medical/dental casting, agriculture (soil conditioner and Ca/S nutrient), food and beverage (additive/firming agent E516), pharmaceuticals (excipient, desiccant) and industrial fillers. Major global manufacturers and board producers integrated with gypsum supply include Saint Gobain Group, Knauf, National Gypsum, Georgia Pacific Gypsum, PABCO, American Gypsum and CNBM/BNBM in China, alongside numerous regional producers of synthetic (FGD) gypsum.
