Track Calcium Sulphate Price Trend Historical and Forecasts

Executive Summary

The global Calcium Sulphate market demonstrated mixed yet structurally resilient pricing dynamics across the second and third quarters of 2025. While Asia-Pacific recorded steady upward momentum driven by infrastructure-led demand, North America experienced fluctuating trends due to uneven construction activity. Europe showed price variability through Q2 followed by a September recovery supported by renewed construction demand.

In China, the Calcium Sulphate Price Index rose by 4.40 percent quarter-over-quarter in Q3 2025, reflecting strong infrastructure-driven consumption. North America witnessed early-quarter strength but experienced a September correction due to slower residential and commercial construction activity. Meanwhile, Europe recorded a September price increase supported by revived construction activity and gypsum-based building material demand.

Across all regions, energy prices, logistics costs, procurement strategies, and inventory positioning played crucial roles in shaping quarterly price movements. Production cost structures remained moderately stable, though energy volatility and freight expenses influenced margins. Looking ahead to Q4 2025, the Calcium Sulphate Price Forecast suggests moderate stability with region-specific upside risks tied to construction recovery and infrastructure spending.

Introduction

Calcium Sulphate is a widely utilized industrial mineral primarily used in gypsum boards, plasters, cement blending, soil conditioning, fertilizers, pharmaceuticals, food processing, and municipal water treatment applications. Given its essential role in construction and infrastructure sectors, its pricing trends often mirror broader macroeconomic and industrial activity.

During Q2 and Q3 2025, the Calcium Sulphate market reflected regionally distinct demand cycles, logistical pressures, and policy-driven infrastructure programs. Seasonal procurement behavior, energy cost fluctuations, and evolving trade flows further contributed to price variability.

This report provides a detailed review of historical quarterly trends, production cost movements, supply conditions, and procurement strategies, along with a forward-looking outlook.

Global Price Overview Q2 and Q3 2025

The global Calcium Sulphate market in 2025 exhibited a differentiated pattern:

APAC demonstrated sustained price increases supported by infrastructure and municipal water treatment demand.
North America showed volatility due to inconsistent construction timelines and regional climate impacts.
Europe recorded fluctuating prices in Q2 followed by a September rebound driven by renewed construction demand.
The interplay between supply stability and demand fluctuations determined price behavior. Logistics and port throughput variability influenced short-term price movements, especially in export-sensitive markets.

Regional Analysis

Asia-Pacific Including China

In Q2 2025, the Calcium Sulphate Price Index in China increased by approximately 1.9 percent in June. The Spot Price reached USD 107 per ton FOB Shanghai. This reflected gradual recovery in infrastructure-led construction activity and water treatment applications.

Public construction projects such as rail, factory infrastructure, and municipal developments supported sustained demand. Construction PMI reaching 52.8 reinforced positive sentiment. Buyers engaged in strategic stockpiling ahead of anticipated Q3 infrastructure rollouts, which further fueled July momentum.

By Q3 2025, the Calcium Sulphate Price Index rose by 4.40 percent quarter-over-quarter. The average quarterly price reached USD 110.67 per metric ton. Spot prices remained firm amid steady supply and robust infrastructure consumption.

September 2025 price momentum was supported by supply constraints within construction and water-treatment supply chains. Rising raw material and energy costs underpinned input pricing, while logistics pressures and seasonal procurement patterns tightened inventories.

Export demand variability moderately influenced pricing due to seasonal procurement shifts and regional policy adjustments. Port throughput fluctuations also affected short-term availability in export markets.

Production cost trends remained balanced. High operating rates and optimized raw material sourcing helped mitigate inventory drawdowns experienced earlier in the year. Energy availability improvements supported stable plant utilization.

The Q4 2025 outlook suggests cautious upside potential, particularly if infrastructure investments remain strong.

North America

The North American Calcium Sulphate market displayed uneven performance across Q2 and Q3 2025.

During April to June 2025, the Price Index fluctuated due to erratic construction timelines and mixed industrial demand. Regional climate disruptions affected project execution. Spot prices remained under pressure amid cautious procurement strategies from water treatment and cement blending industries.

Production costs remained relatively stable. Minor increases in energy and transportation expenses were offset by lower raw material costs. Logistics, particularly cross-state freight movement, created localized cost pressures.

In Q3 2025, early-quarter spot prices recorded moderate increases. However, September witnessed a slight decline.

The September price correction was driven by slower residential and commercial construction activity combined with stable gypsum supply from domestic producers. Inventory levels remained adequate, reducing urgency among buyers.

Procurement behavior turned conservative. Buyers focused on just-in-time purchasing strategies to manage working capital amid uncertain downstream demand. Inventory management across the supply chain remained disciplined.

Looking ahead to Q4 2025, the demand outlook is cautiously optimistic. Seasonal construction recovery and steady cement consumption may support moderate price stability. The forecast indicates potential upward pressure if construction strengthens materially.

Europe

Europe experienced a volatile Q2 2025 marked by fluctuations in Germany and broader regional markets. Price variability reflected instability in construction recovery and inconsistent industrial demand.

Energy market volatility and freight costs influenced production economics. Raw gypsum sourcing challenges further contributed to pricing uncertainty. Producers adjusted plant utilization rates cautiously amid private-sector construction hesitation.

In Q3 2025, the September price environment shifted positively. Prices increased due to recovery in European construction projects and rising demand for gypsum-based building materials across Germany, France, and Italy.

Production costs rose mildly due to higher energy prices and logistics expenses. However, renewed construction momentum improved offtake, supporting firm spot prices.

Demand in gypsum boards, cement, soil amendments, pharmaceuticals, and food processing sectors contributed to improved consumption patterns.

The Q4 outlook remains positive. Residential and commercial construction growth is expected to support moderate price increases, contingent on sustained macroeconomic stability.
