Sodium Chloride in Bulk

Industrial salt is one of the largest tonnage chemicals in use, and the grade matters far more than most buyers expect. Textile dyeing wants low calcium and magnesium; water softening wants hard, slow-dissolving granules; food processing wants refined material with controlled iodine. Gujarat produces the bulk of India's supply. BulkFineChem supplies industrial, refined and vacuum-evaporated grades across India.

Specification

Purity, moisture and calcium plus magnesium content are stated on the batch Certificate of Analysis.

• CAS No. 7647-14-5
• HSN Code 25010090
• Purity 96 to 99.5 percent depending on grade
• Industrial, refined free-flow and vacuum-evaporated grades
• Packing: 50 kg HDPE bags or 1 MT jumbo bags

Applications

State your application when enquiring, since the hardness specification is what separates one grade from another.

• Electrolyte in reactive dyeing of cotton
• Regeneration of water softening resin
• Brine feedstock for chlor-alkali plants
• Food processing, pickling and preservation
• Hide curing in leather tanning

Handling and Storage

Salt is chemically benign but strongly corrosive to steel and concrete in damp conditions, and it cakes readily.

• Store sealed and dry; salt takes up atmospheric moisture
• Keep away from mild steel structures and reinforcement
• Rotate stock to avoid caking
• Confirm whether food grade documentation is required
• SDS issued on request

Ordering

Pricing is quoted against grade, packing and delivery location. Send an enquiry with your tonnage and application.

• Minimum order quantity 1 MT
• GST tax invoice on every order
• Batch-wise Certificate of Analysis with each dispatch

FAQs

Questions buyers commonly ask about industrial salt.

• Which grade for dyeing? Low calcium and magnesium grade, or hardness interferes with the dye bath.
• Is iodised salt available? Iodisation applies to edible grades; confirm your requirement when enquiring.
• Why has my salt set solid? Moisture pickup and recrystallisation; keep bags sealed and dry.
• Can I get a sample? Yes, trial quantities can be arranged.
• What documents are provided? GST invoice, batch CoA, and food grade documents where applicable.
