The global calcium sulfate market size was valued at USD 2.03 billion in 2024 and is estimated to reach USD 3.26 billion by 2033, growing at a CAGR of 5.43% during the forecast period (2025–2033). Key drivers of the market include its growing demand in the construction industry, particularly in gypsum board production, and its use in agriculture as a soil conditioner. Moreover, calcium sulfate is being increasingly utilized in the food and pharmaceutical sectors due to its non-toxic nature and versatile applications.
Calcium sulfate (CaSO₄) is a chemical compound that occurs naturally in various forms, most notably as gypsum (hydrated calcium sulfate) or anhydrite (non-hydrated calcium sulfate). It is widely used in the construction, food, and pharmaceutical industries. In construction, calcium sulfate is used as a binder in drywall and plaster products, while in the food industry, it serves as a food additive commonly identified as E516. It also has applications in agriculture, acting as a soil conditioner. It is crucial in various industrial processes due to its stability, non-toxic nature, and ability to control moisture.
The increasing use of calcium sulfate as a soil conditioner is driven by its ability to enhance soil structure, improve drainage, and reduce soil compaction. Farmers are increasingly adopting gypsum-based soil amendments to boost crop yields and enhance soil health, particularly in regions with high soil salinity.
As climate change and intensive farming practices continue to degrade soil quality, its demand in agriculture is expected to rise, particularly in North America and Europe, where soil management is a growing concern.
The widespread availability of alternatives like calcium carbonate, synthetic gypsum, and other mineral-based additives poses a challenge to the growth of the global market. Many industries, including construction, pharmaceuticals, and agriculture, opt for substitutes due to cost-effectiveness, improved functionality, or easier availability. For instance, calcium carbonate is often preferred in cement and food applications due to its affordability and similar performance characteristics.
Additionally, the increasing production of synthetic gypsum as a by-product of industrial processes provides a sustainable alternative, reducing dependency on natural calcium sulfate sources. As industries seek cost-efficient and eco-friendly options, the competition from these alternatives could limit calcium sulfate’s market share expansion, particularly in price-sensitive regions and applications with flexible material requirements.
The demand for calcium sulfate is rising across multiple industries due to its versatility and functional benefits. In the cosmetics sector, it is gaining traction for its absorbent and texture-enhancing properties. For example,
This launch reflects the growing consumer preference for high-performance beauty products with enhanced durability. Beyond cosmetics, it is widely used in food, pharmaceuticals, and construction materials, further driving its market growth. As industries continue to innovate and seek improved formulations, the adoption of calcium sulfate in diverse applications is expected to expand significantly in the coming years.

The global calcium sulfate market is bifurcated into form, grade, and end-user industry.
Hydrated segment dominates the global market due to its widespread application in various industries, especially in construction. It is primarily used in the production of gypsum plasterboard and cement, which are key materials in the building and construction sector. Hydrated calcium sulfate’s ability to harden and provide structural support makes it indispensable for drywall and ceiling tiles. Moreover, its versatility in applications such as agriculture and food processing, where it acts as a soil conditioner and a food additive, further contributes to its dominance in the market.
The technical grade of calcium sulfate holds a dominant position due to its broad usage across industrial applications. It is widely utilized in the chemical and petrochemical sectors for processes requiring a stable and high-quality material. This grade is commonly used in the production of pigments, paper, and in various industrial manufacturing processes where purity and consistency are crucial. Its role in manufacturing processes, where it serves as a filler or stabilizer, further enhances its dominance. The versatility of technical-grade calcium sulfate across multiple industries ensures its continued market leadership.
The building and construction sector is the dominant end-user industry for calcium sulfate, particularly in the form of hydrated calcium sulfate, commonly used as gypsum in drywall and plaster production. With the increasing demand for residential, commercial, and infrastructure projects, the need for gypsum materials continues to rise. Calcium sulfate plays a crucial role in improving the structural integrity, fire resistance, and soundproofing of buildings. This strong demand for construction materials ensures that the building and construction industry remains the largest consumer of calcium sulfate, driving its market dominance globally.
Based on region, the global calcium sulfate market is bifurcated into North America, Europe, Asia-Pacific, Latin America, and the Middle East and Africa.
Asia-Pacific holds the largest share of the global calcium sulfate market, driven by rapid industrialization, infrastructure development, and strong demand from key end-use industries such as construction, agriculture, and healthcare. Countries like China, India, and Japan are leading consumers due to their expanding construction sectors and increasing focus on soil enhancement for agriculture.
Moreover, the booming real estate market in China, supported by government initiatives for affordable housing, has significantly increased the demand for gypsum-based materials like plasterboard and cement additives. India’s growing agricultural sector is also driving the adoption of gypsum-based soil conditioners to improve crop yields, especially in regions affected by soil salinity.
Furthermore, the increasing focus on healthcare infrastructure in Asia-Pacific, particularly in response to aging populations and expanding healthcare services, is also fueling the use of calcium sulfate in medical applications, such as dental and orthopedic products. With strong economic growth and industrial expansion, Asia-Pacific is expected to maintain its dominance in the global market.
