High Purity Sodium Metabisulfite
High Purity Sodium Metabisulfite from Zhongheng Chemical Co., Ltd. is a white or light yellow crystalline powder with a minimum assay content of 98.0% (as Na2S2O5), designed for applications where stringent purity is critical. The product meets exacting limits for impurities, with Arsenic capped at 0.0001% and Heavy metals (as Pb) at 0.0005%, making it suitable for sensitive uses such as food preservation, water treatment, and pharmaceutical manufacturing. Its pH range of 4.0 to 4.6 and water-insoluble content of 0.05% ensure stability in aqueous solutions, while Iron content is controlled at 0.003% for colour consistency.
Sodium Metabisulfite is a sodium salt of disulfurous acid, commonly used as a reducing agent, antioxidant, and preservative in industrial and food-grade applications. This high-purity grade is produced under controlled conditions to minimise trace contaminants, a standard requirement for products destined for pharmaceutical or potable water systems. Typical industry grades for Sodium Metabisulfite range from 96% to 99% assay, with this 98.0% minimum specification aligning with premium standards for export markets.
Industrial buyers source this grade for water treatment plants, beverage production, and chemical synthesis, where its reducing properties inhibit oxidation and microbial growth. The product is packaged for bulk international shipping, with standard 25 kg or 50 kg bags typical for chemical exports from China. Buyers should confirm packaging compatibility with their handling systems, as Sodium Metabisulfite can degrade in the presence of moisture or air over prolonged exposure.

Sourcing High Purity Sodium Metabisulfite from Zhongheng Chemical Co., Ltd. - China Import Guide
Before ordering, buyers should verify the Certificate of Analysis (COA) for the specific batch to confirm compliance with the 98.0% assay content and impurity limits, such as Arsenic at 0.0001% and Heavy metals at 0.0005%. Requesting third-party lab test results for critical parameters like pH, water-insoluble matter, and Iron content ensures the product meets your application’s regulatory and performance standards.
Confirm the Incoterms, lead time, and packaging details with Zhongheng Chemical Co., Ltd., as these can vary based on order volume and destination. Sodium Metabisulfite is typically shipped in 25 kg or 50 kg multi-layer paper bags with inner polyethylene liners to prevent moisture absorption. Buyers should also clarify whether the supplier can provide palletised or containerised shipments to optimise logistics costs.
Quality checks should include visual inspection for colour consistency and crystalline structure, as well as laboratory tests for assay content, pH, and impurity levels. For food or pharmaceutical applications, request documentation such as a Material Safety Data Sheet (MSDS) and a statement of compliance with relevant standards like FDA or EU regulations. Inspection at the loading port can help ensure the product meets the agreed specifications before shipment.
