Sodium Metabisulfite Supplier in Malaysia
- Also known as
- Sodium Metabisulphite
- SMBS
- Na2S2O5
Sodium metabisulfite, also spelled sodium metabisulphite and commonly shortened to SMBS, is a water-soluble reducing agent supplied as white crystalline powder or granules. ChemTrade handles Malaysian enquiries for food, technical and industrial grades matched to a stated specification.
Food-grade material is selected for qualified antioxidant, preservative and processing applications. Technical and industrial grades are used for water dechlorination, oxygen scavenging and reducing duties in textile, pulp and other manufacturing processes.
This page owns the solid sodium metabisulfite and SMBS identity. It does not treat sodium bisulfite solution, sodium sulphite, sodium sulphide, sodium dithionite or sodium bisulphate as aliases or interchangeable grades.
Send the required grade, assay or impurity limits, application, quantity and delivery location with your enquiry. Availability, packing and documentation are confirmed with the quotation.

Common questions about sodium metabisulfite
What is sodium metabisulfite used for?
Common uses include food processing, water dechlorination, oxygen scavenging and reducing duties in textile, pulp and industrial processes.
Is sodium metabisulfite the same as sodium bisulfite?
No. They are separate product specifications. This page covers solid sodium metabisulfite, while sodium bisulfite solution has its own page.
Does SMBS mean sodium metabisulfite?
Yes in this product context. Expand SMBS in enquiries because the abbreviation can be ambiguous outside the chemical trade.
Which grade should I request?
State food, technical or industrial grade and include the assay, impurity limits and intended application from your specification.
Can packing and documents be confirmed?
Yes. Include preferred packing and required documents. Available options are confirmed for the quoted grade.
What information is needed for pricing?
Send the grade, assay or specification, quantity, application and delivery location. Price validity is stated in the quotation.
