Caustic soda, also known as sodium hydroxide (NaOH), is a strong alkaline chemical widely used in industrial manufacturing and processing. It is used for pH control, chemical processing, cleaning, soap and detergent production, textile processing, pulp and paper manufacturing, and water treatment. Depending on the application, caustic soda is supplied as flakes, pearls, powder, or liquid solution, with each form offering different handling and dissolution characteristics.
For industrial applications, the appropriate caustic soda form and NaOH purity depend on the production process, required concentration, handling method, and technical specifications. Consistent quality is particularly important in bulk applications where variations between batches can affect production performance.

A solid form of sodium hydroxide consisting of thin, white flakes. It is produced by cooling and solidifying concentrated sodium hydroxide.

A finely divided solid form of sodium hydroxide, characterized by its small particle size and white appearance.

A clear aqueous solution of sodium hydroxide, supplied at different concentrations for industrial processes where the liquid form is preferred.

A solid form consisting of small, spherical particles. The uniform shape provides good flow characteristics and consistent particle size.
Caustic Soda comes in four physical forms — chosen based on how the material is handled, not just its industry.
We offer caustic soda flakes in 25 kg and 1,000 kg bags, alongside pearls/pellets (low-dust, easy to dose), micro-pearls (fast-dissolving), and liquid solution (32%–50% concentration, supplied in IBCs or flexi-tanks). Purity ranges from 96% to 99% NaOH depending on grade, with a Certificate of Analysis issued for every shipment.
As one of the largest producers in the region, we run consistent production batches rather than blending stock from multiple sources — which is the main reason buyers see variation between shipments in the first place.
Before dispatch, our lab runs a full analysis and shares the results with you, so you’re confirming the numbers before the order leaves, not after it arrives.
That consistency is what actually matters on your end: fewer rejected batches, no mid-run reformulation, and a raw material input you can plan production schedules around instead of reacting to.
Available Forms:
Form | Purity | Typical Use |
Flakes | 96–99% | General industrial, soap/detergent |
Pearls / Pellets | 99% | Textile, chemical processing |
Micro-pearls | 99% | Fast-dissolving applications |
Liquid (32–50%) | 32–50% NaOH | Water treatment, pulp & paper |
Why Buy Caustic Soda from KaneAra?
If you’re comparing a caustic soda supplier against a trading intermediary, this is usually where the difference shows up — not in the quoted price, but in whether the third shipment matches the first.

Fast & Professional Response · Transparent Contracts
Quoted against your grade, form, volume, Incoterm and destination port — no fixed catalogue rate.
Depending on the application, manufacturers may choose caustic soda pearls, flakes, liquid solution, or other available forms to achieve the required handling, dissolution rate, and production efficiency.
Sodium hydroxide is used to adjust pH, break down organic material, and drive reactions in soap and detergent manufacturing, textile processing (mercerizing), pulp and paper (pulping, bleaching), and water treatment — applications where a shift in purity between batches directly affects the end product.
Caustic soda price tracks global energy and soda ash markets, so we quote per shipment rather than list a fixed rate — this keeps every quote tied to current conditions instead of an outdated number. The minimum order is 20 tons. Before committing, you can request a sample along with the lab’s full analysis report.
