Caustic Soda (Sodium Hydroxide) Supplier in Malaysia
- Also known as
- Caustic Soda
- NaOH
- Lye
ChemTrade supplies caustic soda to industrial buyers across Malaysia. Sold as sodium hydroxide or NaOH, it is one of the most widely used alkalis in Malaysian industry, wherever a process needs a strong, low cost base to raise pH, strip fats or dissolve organics.
We carry it in several forms: flakes and pearls at 99% assay in 25 kg bags, and liquid solution across the commercial range up to 48% in pails, drums, IBCs or bulk. Food grade is available for food processing and equipment cleaning.
The chemistry is the same in each form, so the choice comes down to your dosing setup. Tell us the application and we will recommend the form that lands cheapest.
Caustic soda is a scheduled poison in Malaysia, so supply is subject to you holding the appropriate licence. Tell us the intended use and we will confirm what is needed.

Caustic Soda grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Caustic soda flakes | white flakes | ≥ 99% | The default for most industrial dosing. Easy to store and handle, and dissolves readily when added to water. Used in soap and detergent manufacture, textile processing and general pH correction. | 25 kg bag |
| Caustic soda pearls | white beads | ≥ 99% | Same chemistry as flakes but free-flowing, so it meters more accurately through automated dosing equipment and produces less dust when charged by hand. | 25 kg bag |
| Liquid caustic soda | clear colourless solution | 32% or 48% | Pre-diluted for plants that dose continuously and would rather not handle solids, standard in water and effluent treatment where caustic is fed by pump. 48% carries less freight per tonne of NaOH but needs traced lines in cool conditions. | IBC or bulk |
| Food grade caustic soda | flakes or pearls | ≥ 99% | Meets food-contact specification for use in food processing, peeling, curing, and equipment cleaning on production lines. | 25 kg bag |

Caustic Soda applications
Safety and handling
- Classification
- corrosive, causes severe skin burns and eye damage
- UN number
- 1823
- Hazard class
- 8
Store sealed in a dry area away from acids, aluminium, zinc and tin, because contact with those metals releases hydrogen. Solid caustic absorbs moisture and carbon dioxide from the air, so keep bags closed. Always add caustic to water, never water to caustic: dilution releases enough heat to boil and spit. Handle with chemical goggles, a face shield, gloves and an apron.
Common questions about caustic soda
Which form should I order, flake, pearl or liquid?
Flake and pearl are the same chemistry at the same assay; pearls are free-flowing so they meter better through automated dosing and raise less dust when charged by hand. Liquid saves you dissolving it, and at 48% the freight cost per tonne of NaOH is lower, but it needs traced lines in cool conditions. Tell us what you are dosing into and we will say which is cheaper delivered.
Do I need a licence to buy caustic soda in Malaysia?
Yes. Caustic soda is a scheduled poison in Malaysia, so supply is subject to you holding the appropriate licence or permit for your use. We will tell you what is needed for your application and what documentation to have ready before the first delivery.
What assay and impurity levels do you supply?
Solid grades run at 99% NaOH minimum with carbonate typically under 0.5% and chloride under 0.03%. Liquid is available across the usual commercial range from dilute solutions up to 48%. If your process has a tighter limit on iron, chloride or carbonate, send us the specification and we will source against it rather than send you the nearest thing.
Can you supply food grade?
Yes, in flake and pearl. Specify food grade when you enquire and it ships with the corresponding documentation for food-contact use, peeling, curing, and equipment cleaning on production lines.
What packing is available?
Solids in 25 kg bags, and liquid in pails, jars, drums, IBCs and bulk tanks. We work with several producers, so if you need a size that is not standard we can usually source it.
How is it priced?
Prices move from time to time, so we quote a current price with a stated validity period rather than publish one that would soon be out of date. Send us the grade and quantity and we will come back with a figure.
