Industrial sodium chloride (NaCl) for chemical-industry buyers

Bulk NaCl formats and current commercial starting points

Sodium chloride, common salt and industrial salt are overlapping commercial names, but the requested grade still controls the offer. India Salt's industrial catalogue covers crystalline commodity NaCl supplied loose or in 25 kg and 50 kg PP bags. It does not claim laboratory-reagent, analytical, pharmaceutical or injectable grade.

The prices below are ex-refinery catalogue starting points for the first volume band. Quantity discounts are calculated on the product page. Generic packing and loading are included for bagged products; freight, custom packing, special testing and any tighter chemistry are confirmed for the actual order.

Why minor constituents matter

Sodium chloride percentage is only one line in an industrial specification. Calcium and magnesium can increase brine-treatment load; sulphate, insolubles and iron can affect downstream operation, colour, filtration or residue. Moisture changes flow behaviour and the dry-salt content delivered per tonne.

The relative importance of each parameter depends on the process. A buyer should involve the plant or quality team before a commercial order and define which values are rejection criteria, which are informational and which testing method governs a dispute.

Build an RFQ that suppliers can answer correctly

Include the intended process, required standard or full parameter table, monthly and lot quantity, packing, dispatch cadence, delivery location, sample protocol, test-certificate requirement and acceptance process. State whether the commercial quote should be ex-works, FOR destination or another defined basis.

For a new source, use a representative sample or paid commercial trial before committing the full monthly programme. A lab result from a small sample is useful, but it should be paired with a plan for lot identification and consistent dispatch.

• NaCl on the agreed basis
• Moisture and insoluble matter
• Calcium, magnesium, sulphate and iron limits
• Particle size if relevant
• Sampling, test method and certificate issuer
• Packing, lot size and delivery schedule

Trial, COA and acceptance workflow

A credible sequence is requirement review, representative sample or paid trial, agreed acceptance table, lot-linked certificate, first commercial dispatch and performance review. The buyer should decide whether an internal manufacturer COA is sufficient or whether an independent, NABL-accredited or government laboratory is required for the named method.

Keep the approved specification and the delivered-lot identity together. A report from another product, plant or month is background evidence; it is not proof of the truck at the gate. If the buyer will test after arrival, the purchase order should define joint sampling, retained samples, turnaround time and the consequence of a disputed result.

Commercial comparison after technical qualification

Compare only technically acceptable offers. Then normalize product price, packaging, testing, freight, unloading, credit and expected process loss. A low salt rate can be uneconomic if it raises brine purification cost, waste, downtime or rejection risk.

India Salt publishes a commercial base rate and supports quantities from 1 MT. The plant specification must still be accepted in writing before any page should be treated as a technical offer.
