Executive Summary

The global Calcium Sulphate prices market displayed mixed yet structurally supportive trends during the quarter ending September 2025 (Q3 2025). While Asia-Pacific (APAC), particularly China, experienced a clear upward movement driven by infrastructure-led demand, North America and Europe witnessed region-specific fluctuations influenced by construction activity, energy costs, and logistics dynamics. Overall, Calcium Sulphate Price Index movements reflected balanced supply conditions, moderate cost pressures, and steady downstream demand from construction, cement, gypsum boards, and industrial applications. As the market enters Q4 2025, the Calcium Sulphate price forecast indicates cautious optimism, supported by seasonal construction recovery and infrastructure investments.

Introduction: Understanding the Calcium Sulphate Market

Calcium Sulphate is a critical industrial mineral widely used in gypsum boards, plasters, cement manufacturing, soil conditioning, fertilizers, pharmaceuticals, and food processing. Due to its broad downstream exposure, Calcium Sulphate prices are closely tied to construction cycles, infrastructure spending, energy costs, and logistics efficiency.

During Q3 2025, regional Calcium Sulphate price trends diverged, reflecting varied economic conditions, construction momentum, and policy environments across APAC, North America, and Europe. 

Global Calcium Sulphate Price Overview – Q3 2025

Globally, the Calcium Sulphate Price Index showed mild upward bias during Q3 2025, supported by infrastructure projects in Asia and gradual recovery in European construction. However, stable supply availability and disciplined procurement limited sharp price escalation. Seasonal demand patterns and regional logistics performance played a significant role in shaping spot price movements across key markets.

Asia-Pacific (APAC) Calcium Sulphate Prices Analysis

China Calcium Sulphate Price Trend – Q3 2025

In China, the Calcium Sulphate Price Index rose by 4.40% quarter-over-quarter in Q3 2025. This increase was primarily underpinned by infrastructure-driven demand, particularly from public works, urban development projects, and municipal water infrastructure.

The average Calcium Sulphate price in China during the quarter stood at approximately USD 110.67/MT, reflecting firm market fundamentals.

Spot Price and Market Dynamics

The Calcium Sulphate Spot Price remained firm throughout the quarter, supported by:

• Steady domestic supply levels
• Strong procurement from infrastructure and construction contractors
• Controlled inventory management by producers

Despite mixed regional dynamics within APAC, the overall market maintained an upward trajectory due to seasonality and ongoing project execution.

Production Cost and Logistics Impact

The Calcium Sulphate Production Cost Trend in APAC was influenced by:

• Feedstock price movements
• Fluctuating energy costs
• Port throughput and inland logistics variability

While cost pressures were present, they remained manageable, preventing excessive price volatility.

Demand Outlook and Price Forecast – APAC

The Calcium Sulphate Demand Outlook in APAC remains supported by:

• Infrastructure expansion
• Municipal water treatment projects
• Public construction spending

The Calcium Sulphate Price Forecast suggests cautious upside potential, contingent on sustained construction activity and stable export demand. However, seasonal procurement patterns and policy-driven export variability may intermittently influence pricing.

North America Calcium Sulphate Price Trends

Market Performance in Q3 2025

In North America, the Calcium Sulfate Price Index exhibited noticeable fluctuations throughout Q3 2025. Prices increased moderately in early Q3, driven by construction and cement sector demand, before softening toward the end of September.

The Calcium Sulfate Spot Price reflected uneven demand across:

• Residential construction
• Commercial projects
• Gypsum board manufacturing

Why Calcium Sulphate Prices Changed in September 2025

Prices declined in September 2025 due to:

• Slower construction activity in residential and commercial sectors
• Stable gypsum supply from domestic producers
• Cautious buying behavior amid uncertain demand signals

These factors collectively eased upward price pressure toward quarter-end.

Production Cost and Supply Conditions

The Calcium Sulfate Production Cost Trend in North America remained relatively stable. Minor increases in:

• Energy costs
• Transportation expenses

were largely offset by lower raw material costs, allowing producers to maintain competitive pricing.

Demand Outlook and Price Forecast – North America

Looking ahead, the Calcium Sulfate Demand Outlook for Q4 2025 is cautiously optimistic, supported by:

• Seasonal construction recovery
• Consistent cement industry demand

The Calcium Sulfate Price Forecast suggests moderate stability, with potential upside if construction momentum strengthens toward year-end.

Europe Calcium Sulphate Price Analysis

European Market Overview – Q3 2025

In Europe, the Calcium Sulfate Price Index fluctuated during Q3 2025. Spot prices were influenced by uneven construction activity across Germany, France, and Italy, alongside regional logistics and energy cost variations.

The Calcium Sulfate Spot Price gained momentum toward September as construction activity showed signs of recovery.

Why Prices Increased in September 2025

European Calcium Sulphate prices increased in September 2025 due to:

• Resumption of delayed construction projects
• Rising demand for gypsum-based building materials
• Improved procurement activity from contractors and manufacturers

Downstream Uses and Demand Structure

In Europe, Calcium Sulphate is extensively used in:

• Gypsum boards and plasters
• Cement production
• Soil amendments
• Pharmaceuticals and food processing

This diversified downstream exposure helped stabilize demand during periods of construction volatility.

Production Cost Trend and Outlook

The Calcium Sulphate Production Cost Trend in Europe experienced a mild increase, primarily driven by:

• Higher energy prices
• Elevated logistics and transportation costs

Despite this, producers managed pricing carefully to avoid demand erosion.

The Calcium Sulphate Demand Outlook for Q4 2025 remains positive, with expectations of growth in both residential and commercial construction. Consequently, the Calcium Sulphate Price Forecast indicates potential moderate price increases if construction activity remains resilient.

Conclusion: Calcium Sulphate Market Outlook

The Calcium Sulphate prices market in Q3 2025 reflected a balance between supportive demand fundamentals and controlled supply conditions. APAC led the upward momentum, while North America and Europe showed region-specific fluctuations shaped by construction cycles and cost dynamics.

As the market transitions into Q4 2025, Calcium Sulphate price trends are expected to remain stable to mildly bullish, supported by infrastructure investments, seasonal construction recovery, and diversified downstream demand. However, logistics performance, energy prices, and procurement strategies will continue to play a decisive role in shaping future Calcium Sulphate Price Index movements.
