Description
Sodium Metabisulphite Supplier & Exporter in India
Sodium Metabisulphite releases sulphur dioxide in solution, and that single property drives every one of its uses. It kills spoilage organisms, mops up dissolved oxygen before oxidation can start, strips residual chlorine ahead of reverse osmosis membranes, and bleaches without the harshness of chlorine chemistry.
Rexus Pharma Chem LLP supplies and exports Sodium Metabisulphite in bulk to food and beverage processors, water treatment companies, textile and leather units, mining operations and photographic chemical manufacturers across India, Africa and the Gulf. Minimum order quantity is 500 kg.

Minimum Order Quantity and Despatch
The minimum order quantity for Sodium Metabisulphite is 500 kg. Packing is supplied in standard commercial sizes for this material, and the exact pack size is confirmed against your enquiry along with the price and lead time. Mixed consignments with other products from our range can be combined into a single despatch, and export orders are shipped with COA, MSDS and the full set of documents required at destination.
Storage and Handling
Store in tightly sealed packing in a cool, dry, well-ventilated place away from moisture, acids and oxidising agents. Contact with acid liberates sulphur dioxide gas, and the material loses strength slowly on air exposure, so keep containers closed and stock rotated.
Frequently Asked Questions
What is SMBS used for in water treatment?
It is dosed ahead of reverse osmosis membranes to remove residual chlorine, which would otherwise oxidise and destroy the membrane. It is also used as an oxygen scavenger in boiler and injection water.
What is the minimum order quantity?
The minimum order quantity is 500 kg.
Is food grade material available?
Food grade and technical grade are both offered. Confirm the application and we will quote the matching grade.
Why does the material smell of sulphur?
Sodium Metabisulphite slowly releases traces of sulphur dioxide, which is what produces the characteristic odour. A strong smell from a sealed pack suggests moisture ingress or age, so store it dry and rotate stock.
Do you supply COA and MSDS?
Yes, with every consignment.
