Industrial Salt Manufacturer in India: Products, Uses & Applications
Salt is far more than a kitchen staple. Across India’s manufacturing sector, industrial salt is a fundamental raw material which is used in chemical production, water treatment, textile dyeing, paper processing and more. As one of the world’s largest salt producers, India is home to a substantial base of industrial salt manufacturers, with Gujarat at the centre of this output
What is industrial salt?
Industrial salt refers to sodium chloride (NaCl) produced and graded for non-food applications. Unlike edible salt, it does not require iodisation or food safety fortification but it must meet precise purity and particle size specifications that vary by industry. In India, industrial salt is produced primarily through solar evaporation of seawater, a process well-suited to Gujarat’s coastal geography and arid climate. The resulting salt is screened and graded by industrial salt manufacturers into distinct grades for different end uses.Key industrial salt grades
• Medium Crystal Salt: High-purity NaCl (98.5%-99.5%) with uniform grain size. The most widely used industrial grade, suited for water softening, chemical manufacturing and ion exchange processes.•Semi Medium Crystalline Salt: Particle sizes between fine and medium, offering improved solubility over coarser grades. Widely used in detergent and soap manufacturing.
• Super Fine Powder (SFP): Ultra-fine salt for dye manufacturing, metal treatment and precision chemical formulation.
• Salt Tablet: Compressed salt pellets for water softening and ion exchange systems. Super Salts produces this grade as a tablet salt manufacturer for industrial and commercial water treatment facilities.
Industrial salt applications in India
Chemical Manufacturing: Industrial salt is the primary feedstock for producing chlorine, caustic soda and soda ash which are essential inputs for plastics, paper, textiles and cleaning products. India’s chlor-alkali industry consumes millions of tonnes annually.Water Treatment: Salt regenerates ion exchange resins in water softening systems, removing calcium and magnesium that cause hardness. Medium crystal salt and tablet salt are the preferred grades for this industrial salt application.
Textile and Dyeing: Salt fixes reactive dyes to fabric during textile processing. Consistent purity and grain size are critical to achieving uniform colour uptake across production batches.
Paper and Pulp: Sodium chloride contributes to chlorine dioxide production used in pulp bleaching. Industrial salt manufacturers supply high-purity grades that minimise process residue.
De-icing: Industrial salt is used on roads, runways and industrial areas in India’s colder northern and high-altitude regions during winter months.
