Magnesium Sulphate Market Set to Surge to USD 1.48 Billion by 2030 — Driven by Rising Agricultural Demand and Pharmaceutical Applications

 The global magnesium sulphate market is projected to grow at a compound annual growth rate (CAGR) of 5.8% between 2025 and 2030, expanding from an estimated USD 1.05 billion in 2024 to approximately USD 1.48 billion by 2030. This robust growth trajectory is fueled by surging demand across agriculture, pharmaceuticals, water treatment, and construction industries.

 Agriculture Emerges as Leading Driver

Magnesium sulphate’s most significant growth comes from the agriculture sector, accounting for nearly 45% of total demand in 2024. With soil depletion and magnesium deficiency in farmlands rising globally, farmers are increasingly turning to magnesium sulphate — commonly sold as Epsom salt — to boost crop yield and enhance soil nutrient composition. In regions such as Latin America and Southeast Asia, agricultural use of magnesium sulphate soared by over 12% in 2024, compared with the prior year, largely driven by staple crops like rice, wheat, and corn.

Recent field trials in India recorded a 7–9% increase in crop yields in magnesium-deficient soils treated with magnesium sulphate, supporting wider adoption among both smallholder and commercial farms. This rise reflects broader agricultural sustainability efforts and soil health restoration measures supported by government subsidies in various emerging economies.

Pharmaceutical & Healthcare Demand on the Rise

The pharmaceuticals and healthcare segment contributed approximately 25% of market demand in 2024, and is projected to grow at the fastest segmental CAGR of 6.5% through 2030. Magnesium sulphate’s medical uses — such as in intravenous solutions for treating eclampsia, acute asthma attacks, and magnesium deficiency — are seeing renewed importance amid increasing maternal healthcare needs and rising prevalence of chronic respiratory conditions globally.

In 2024 alone, hospital procurement of injectable magnesium sulphate increased by 8.4%, especially in Asia-Pacific and Latin America, where healthcare infrastructure continues to scale. The demographic shift toward ageing populations in Europe and North America is also expected to further drive demand, as magnesium deficiency-related treatments become more commonplace.

Water Treatment and Industrial Uses Add Momentum

Beyond agriculture and medicine, magnesium sulphate plays a growing role in water treatment and industrial processes. Usage in wastewater neutralization and as a coagulant constituent in municipal water treatment facilities grew by approximately 6% worldwide in 2024, contributing to around 15% of total market consumption. In addition, the construction industry—particularly in cement setting and dust suppression applications—has begun incorporating magnesium sulphate, boosting demand in developing regions where infrastructure activities are ramping up.

Asia-Pacific Leads Global Market Growth

Geographically, the Asia-Pacific region dominated with over 40% share of global magnesium sulphate consumption in 2024, followed by North America (22%) and Europe (18%). Within Asia-Pacific, India and China together accounted for nearly 60% of regional demand, spurred by expansive agricultural activity and growing healthcare expenditure. The Middle East & Africa region is also emerging, with a projected CAGR of 7.2%, fueled by infrastructure development and increasing magnesium deficiency awareness in soils.

Supply Constraints and Raw Material Challenges

Despite the optimistic growth outlook, the market faces potential headwinds. Tightening raw material supplies — particularly of mining-derived magnesium salts — is fueling periodic price fluctuations. As of Q3 2025, magnesium sulphate prices rose by approximately 9% globally compared to the same period in 2024, affecting affordability in price-sensitive markets. Suppliers are increasingly exploring recycled magnesium sources, and some are turning to sea-water derived magnesium extraction to stabilize supply chains.

Key Players and Market Consolidation

The global market remains moderately fragmented. However, recent consolidation trends are underway, driven by acquisitions and capacity expansions. Leading producers such as MagChem Industries, Global Minerals Co., and AquaSalts Ltd. have together increased their combined output by nearly 18% in 2024–2025 to capture growing demand.

To meet the rising pharmaceutical-grade demand, several companies ramped up GMP-certified (Good Manufacturing Practice) production lines — increasing capacity for injectable-grade magnesium sulphate by roughly 25% in 2025 compared to 2023.

Additionally, a growing number of regional producers in India, Brazil, and Southeast Asia have entered the market, offering cost-competitive magnesium sulphate — including high-purity mono- and heptahydrate variants — to meet both agricultural and industrial demand.

Market Outlook: Trends and Opportunities

• Sustainable Agriculture & Soil Health Programs: Governments across Asia-Pacific and Latin America are launching subsidized soil health campaigns. These initiatives encourage the use of nutrient-enriching supplements like magnesium sulphate, which analysts believe will sustain double-digit growth in those regions through 2028.

• Increased Healthcare Spending and Maternal Health Focus: With maternal health and chronic disease care gaining priority, injectable and pharmaceutical-grade magnesium sulphate demand is expected to rise. This trend is especially pronounced in developing economies improving their hospital infrastructure.

• Expansion of Recycled & Alternative Magnesium Sources: To alleviate raw material supply constraints, manufacturers are investing in magnesium recycling programs and exploring seawater-extraction technologies. This could stabilize or even reduce product pricing starting late 2026.

• Growth in Industrial & Infrastructure Sector Demand: As construction and water treatment projects expand globally, magnesium sulphate’s role as a setting accelerator in concrete or as a neutralizing agent in wastewater treatment is expected to grow, boosting demand from non-traditional sectors.

Quote from Industry Analyst

“With global agriculture facing escalating soil nutrient depletion, and healthcare systems expanding rapidly in emerging economies, magnesium sulphate is uniquely positioned to serve both sectors. Its dual-use — across food security and maternal health — makes it one of the most versatile commodity minerals in the coming decade,” said a senior market analyst.

Conclusion

As the global economy continues to evolve, growing demand for magnesium sulphate across agriculture, healthcare, industrial, and environmental sectors is driving sustained market growth. For stakeholders — from producers and distributors to end-user industries — the next five years offer considerable opportunity. With supply chain innovations and increasing regulatory focus on soil and public health, magnesium sulphate is set to cement its status as a critical and steadily expanding commodity.
