Category: Sodium Metabisulfite

Bergano Chemical supplies and exports sodium metabisulfite in food, industrial, high-purity and refined grades. We provide specifications, samples and supporting product documentation for product approval and order planning.

Start with your application and required specification, then select a grade from the listed products.

Select a sodium metabisulfite grade

• Food grade: For food-processing purchases requiring food-grade specifications, with control of arsenic, lead and solution clarity.
• Industrial grade: For reducing and bleaching applications in textile, leather and chemical processing, where assay, iron and water-insoluble matter determine acceptance.
• High-purity grade: For solution preparation where clarity, iron content and pH are part of incoming quality control.
• Refined grade: The highest grade in Bergano’s sodium metabisulfite supply range, with specified controls for chloride, iron and water-insoluble matter. Compare the individual specification limits with your purchasing requirements; the grade designation does not mean every parameter is tighter than in every other grade.

If you are replacing an existing supply, send the current specification rather than only a grade name. This lets us quote against the same acceptance criteria.
