Calcium Sulphate Prices in APAC

China Leads the Regional Price Rally

In China, the Calcium Sulphate Price Index rose by 18.07% quarter-over-quarter in Q4 2025, marking one of the most significant regional increases globally. The surge was primarily attributed to supply constraints and firm domestic demand.

The average Calcium Sulphate price during the quarter stood at approximately USD 130.67 per metric ton (MT), reflecting strong procurement activity from downstream industries.

Key Drivers Behind the Price Increase

Supply Constraints

Production rates among key Chinese manufacturers remained controlled during the quarter. Maintenance shutdowns at certain facilities, coupled with environmental compliance measures, limited output availability. Reduced operating rates tightened market supply, pushing prices upward.

Construction Sector Demand

The revival of residential and commercial construction projects in China supported consistent demand for gypsum boards and cement-based materials. Infrastructure expansion projects, particularly in urban redevelopment zones, also increased consumption of calcium sulphate derivatives.

Export Activity

China continued to serve as a major supplier to neighboring Asian markets. Increased export inquiries from Southeast Asia contributed to supply tightness domestically, reinforcing upward price pressure.

Raw Material and Logistics Costs

Elevated transportation and handling costs further added to pricing strength. Producers passed through higher freight and operational expenses to buyers, sustaining the bullish market environment.

Market Outlook in APAC

The APAC market ended Q4 2025 on a firm note. While supply improvements may occur in early 2026, sustained construction demand is expected to keep Calcium Sulphate Prices relatively stable to firm in the near term.

Calcium Sulphate Prices in North America

Firm Demand Supports Upward Momentum

The Calcium Sulphate Price Index in North America increased during Q4 2025, reflecting robust demand from construction and infrastructure projects alongside tighter supply from key domestic producers.

Strength in Spot Market

The Calcium Sulphate Spot Price showed noticeable firmness throughout the quarter. Limited regional inventory levels and ongoing commercial and residential construction activities enhanced seller leverage.

Major Market Drivers

Infrastructure and Housing Projects

The continuation of federally backed infrastructure programs in the United States significantly boosted demand for construction materials. Commercial developments, road expansions, and residential housing projects sustained consumption of gypsum boards and cement retarders.

Tight Domestic Production

Several domestic producers operated at optimized but controlled capacity levels. Any temporary outages or maintenance periods had an immediate impact on supply availability, preventing stock accumulation.

Inventory Management

Regional inventories remained relatively low. Distributors maintained lean stock positions, preferring short-term procurement strategies. This limited buffer amplified price sensitivity to supply disruptions.

Stable Import Flows

Although imports supplemented domestic supply, shipping lead times and freight volatility limited immediate availability. This prevented price corrections and supported sustained firmness in the market.

Pricing Behavior

Throughout Q4 2025, sellers maintained strong pricing discipline. Buyers seeking bulk volumes encountered firm offers with minimal discounts. The upward trajectory reflected a structurally balanced but tight supply-demand environment.

North American Market Outlook

Entering 2026, Calcium Sulphate Prices in North America are expected to remain stable to firm. Continued infrastructure investments and steady housing demand will likely prevent significant price declines in the short term.

Calcium Sulphate Prices in Europe

Tight Supply and Export Activity Drive Price Gains

The Calcium Sulphate Price Index in Europe rose during Q4 2025, reflecting tight domestic supply, steady demand from gypsum board and cement manufacturers, and active export bookings.

Spot Prices Strengthen

The Calcium Sulphate Spot Price strengthened as inventories in key European ports remained low. Buyers continued active procurement for infrastructure and building projects, limiting supply flexibility.

Key Factors Influencing European Prices

Low Port Inventories

Major European ports reported reduced stock levels during the quarter. Strong domestic demand combined with export shipments restricted available material for spot buyers.

Cement and Gypsum Industry Demand

Europe’s cement and plasterboard manufacturing sectors maintained consistent procurement volumes. Renovation activities and green building initiatives supported sustained gypsum demand.

Export Commitments

European producers fulfilled export contracts to neighboring regions, which reduced domestic availability and contributed to tighter supply conditions.

Energy and Production Costs

Although energy prices stabilized compared to earlier volatility, production costs remained relatively elevated. Producers factored these operational costs into selling prices.

Market Sentiment

Market sentiment in Europe remained cautiously optimistic. Buyers secured material in advance to hedge against further price increases, sustaining a firm trading environment.

European Market Outlook

With supply expected to remain controlled and infrastructure initiatives ongoing, Calcium Sulphate Prices in Europe may continue to show resilience into early 2026. However, improved production rates could gradually ease pressure if demand stabilizes.

Comparative Regional Analysis – Q4 2025

Among all regions, China recorded the sharpest quarter-over-quarter increase, while North America and Europe experienced steady but firm upward adjustments.
