Calcium Sulfate Prices Remain Stable Across Americas, Canada at USD 217/MT and Argentina at USD 177/MT

17-Dec-2025

Calcium sulfate (CaSO4) is an inorganic mineral compound existing in various hydrated forms, most notably as gypsum (dihydrate) and anhydrite. This versatile white crystalline substance demonstrates moderate water solubility and serves critical functions across multiple industries. Its widespread applications span construction materials including drywall, plaster, and cement formulations, water treatment processes, food processing as a coagulant and firming agent, pharmaceutical excipients, and agricultural soil amendments. Given its integral role in construction activity and industrial manufacturing, calcium sulfate pricing remains particularly responsive to building sector dynamics, regulatory compliance requirements, and upstream raw material availability.

Global Market Overview:

The global calcium sulfate market reached a volume of 171.75 Million Tons in 2025. Market projections indicate expansion to approximately 231.25 Million Tons by 2034, reflecting a compound annual growth rate (CAGR) of 3.36% throughout the 2026-2034 forecast period. This sustained growth trajectory is underpinned by expanding construction materials consumption, increasing utilization in industrial filler applications, rising adoption across food and pharmaceutical sectors, and evolving regulatory emphasis on high-quality mineral compounds for environmental and industrial applications.

What Moved Prices:

France: Calcium sulfate prices advanced to USD 223/MT in September as evolving construction sector activity influenced procurement patterns and shaped supplier negotiations. Fluctuating operational efficiencies among domestic manufacturers affected output consistency, prompting buyers to recalibrate sourcing schedules and inventory planning throughout the quarter.
Japan: Prices climbed to USD 332/MT, the highest among tracked regions, supported by resilient consumption from building materials and industrial filler applications. Manufacturers navigated shifting cost dynamics while freight coordination across regional shipping lanes affected cargo arrival timing, encouraging more strategic inventory management approaches among buyers.
Germany: The market registered USD 166/MT as procurement patterns in construction and industrial additive applications guided offtake volumes. Local producers recalibrated operating strategies to align with environmental and regulatory compliance frameworks, contributing to periodic supply adjustments and supporting modest price appreciation.
Canada: Prices edged higher to USD 217/MT as consistent industrial demand encouraged distributors to maintain steady inventory flows. Producers adapted manufacturing schedules in response to evolving operational conditions, while cross-border trade movements influenced regional freight dynamics and delivery planning considerations.
Argentina: Market values reached USD 177/MT reflecting ongoing adjustments in local manufacturing output that shaped supply-demand equilibrium. Procurement teams exercised caution amid evolving transportation coordination within regional logistics networks, while downstream sectors calibrated purchase volumes with moderated project activity timelines.

Drivers Influencing the Market:

Several factors continue to shape calcium sulfate pricing and market behavior:

Construction Sector Demand: Building materials consumption, particularly for gypsum board, plaster, and cement applications, remains the primary demand driver. Housing starts, commercial construction activity, and infrastructure development directly influence procurement volumes and regional pricing dynamics.
Industrial Filler Applications: Growing utilization across plastics, paper, and industrial compound formulations provides supplementary demand support. Manufacturers seeking cost-effective mineral fillers with desirable physical properties continue driving incremental consumption growth.
Food and Pharmaceutical Sectors: Expanding applications in food processing as a coagulant and firming agent, combined with pharmaceutical excipient demand, create additional market opportunities. Regulatory quality standards influence grade specifications and pricing premiums.
Agricultural Applications: Fertilizer manufacturing and soil amendment usage, particularly for sulfur-based agricultural products, contribute to overall demand patterns. Seasonal planting cycles influence procurement timing in agricultural end-use segments.
Environmental Regulations: Compliance requirements and environmental frameworks guide producer operating strategies, affecting output consistency and supply availability. Flue gas desulfurization and water treatment applications reflect regulatory-driven demand components.
Logistics and Transportation: Freight coordination, cross-border trade movements, and regional shipping dynamics influence delivery lead times and procurement planning. Transportation cost fluctuations affect landed prices and regional price differentials.

Recent Highlights & Strategic Developments:

Recent strategic moves within the industry further illustrate evolving dynamics:

In April 2025, SUL4R-PLUS inaugurated a calcium sulfate fertilizer production facility in Marissa, Illinois, featuring annual capacity of 100,000 tons. This expansion underscores the company's strategic commitment to strengthening manufacturing capabilities and meeting rising demand for premium sulfur-based agricultural inputs.

Outlook & Strategic Takeaways:

Looking ahead, the calcium sulfate market is positioned for sustained growth driven by construction sector recovery, expanding industrial applications, and increasing regulatory emphasis on high-quality mineral compounds across environmental and manufacturing sectors.

To navigate this complex landscape, stakeholders should:

Monitor Regional Price Movements: Track monthly and quarterly price developments across key markets to identify procurement timing opportunities and anticipate cost structure changes that may affect operational budgeting and supplier negotiations.
Benchmark Procurement Strategies: Evaluate regional price differentials to optimize sourcing decisions and leverage competitive pricing environments. Consider multi-source procurement approaches to enhance supply security and cost efficiency.
Track Construction Sector Indicators: Monitor housing starts, commercial building permits, and infrastructure project pipelines as leading indicators of demand trajectory. Construction activity remains the primary consumption driver for calcium sulfate products.
Assess Industrial Application Trends: Evaluate growth patterns in filler applications, food processing, and pharmaceutical segments to identify emerging demand opportunities and potential premium pricing segments.
Diversify Supply Sources: Develop relationships with multiple suppliers across different geographic regions to mitigate supply disruption risks and maintain procurement flexibility during periods of market volatility.
Monitor Regulatory Developments: Stay informed about environmental compliance requirements and quality standards that may affect producer operating strategies, supply availability, and grade-specific pricing dynamics.
Evaluate Logistics Efficiency: Assess transportation options and freight coordination strategies to optimize landed costs and ensure reliable delivery schedules that support operational continuity.
