Introduction
The global inorganic salts market was estimated to be worth about USD 92.2 billion in 2021, and is projected to reach roughly USD 123.5 billion by 2028, representing a compound annual growth rate (CAGR) of around 4.9%. Inorganic salts—metal cations paired with non-metal anions—serve as fundamental chemical inputs across agriculture, food & beverage, water treatment, pharmaceuticals and industrial applications.

Applications
These salts have broad usage: in agriculture, potash salts and ammonium-based salts support soil fertility and crop yield; in food & beverage they act as preservatives and additives; in water treatment they serve as coagulating/flocculating agents; and in pharmaceuticals they are employed as excipients, reagents and in medical formulations.

Key Drivers
Growth is propelled by rising agricultural demand (driven by global population growth and food security needs), expanding water-treatment infrastructure, increasing pharmaceutical output and industrialization in emerging markets. Meanwhile, cost pressures and supply-chain complexity of raw materials such as minerals impose some restraint.

Future Opportunities
Looking ahead, opportunities emerge in specialty salts and high-purity grades for advanced applications (e.g., battery electrolytes, specialty chemicals), sustainable agriculture formulations and emerging geographies—especially Asia-Pacific—where growth is strongest. Manufacturers that invest in eco-friendly processes, differentiated product portfolios and service-oriented supply models are poised to capture value.
