According to latest industry data, the Global Sodium Bisulphite (CAS 7631-90-5) Market was valued at approximately USD 515.6 Million in 2025 and is projected to reach USD 842.4 Million by the year 2036, growing at a CAGR of 4.6% during the forecast period.
Sodium Bisulphite (E222) is an inorganic chemical compound that serves as a versatile reducing agent, antioxidant, and antimicrobial agent. Its primary utility spans from the dechlorination of municipal wastewater to the preservation of nutritional integrity in the food industry. The 2025 market report highlights an industry undergoing a technical shift toward automated, high-purity manufacturing processes. As environmental regulations surrounding water discharge become more stringent globally, Sodium Bisulphite has emerged as a critical chemical for industrial effluent treatment.
The pandemic caused a transient imbalance in the market. While industrial demand from the textile and paper sectors dipped in 2020 due to factory lockdowns, the demand for water treatment and food preservation remained resilient. Supply chain disruptions, particularly in the sourcing of sulfur and soda ash, led to short-term price volatility. Post-pandemic, the market has seen a "Green Recovery," with increased investments in municipal water infrastructure and a surge in the processed food sector, driving a steady rebound in consumption.
By Type (Grade):
Technical Grade: The largest segment by volume, utilized extensively in industrial wastewater treatment, paper bleaching, and the textile industry.
Food Grade: High-purity grade used as a preservative (E222) in wines, dried fruits, and seafood to prevent oxidation and microbial growth.
Photo/Electronic Grade: Specialized grade with ultra-low impurity levels for use in the photography industry and semiconductor cleaning.
By Application:
Water Treatment: Primarily used for dechlorination in municipal water plants and the neutralization of cyanide in mining effluents.
Paper & Pulp: Utilized for peroxide neutralization and as a bleaching agent in mechanical pulp.
Food & Beverage: Used for enzymatic browning prevention and as a fermentation stabilizer in viticulture.
Chemical Synthesis: Acts as a reducing agent in the production of surfactants, dyes, and pharmaceuticals.
Textile & Leather: Used for removing excess chlorine from bleached fabrics and in the tanning process.
Asia-Pacific: The dominant market (approx. 45% share), led by China and India. Rapid urbanization and the expansion of the manufacturing and textile sectors drive high demand.
North America: Driven by strict EPA regulations regarding water discharge and a robust processed food industry.
Europe: Focused on high-purity food-grade applications and sustainable water management practices.
South America & Middle East: Emerging demand from the mining sector (effluent treatment) and desalination plants.
The market is characterized by a mix of diversified chemical giants and specialized inorganic salt producers:
Global Leaders: BASF SE, Solvay S.A., Dow Chemical Company, Aditya Birla Chemicals, Calabrian Corporation (INOCC), Kuhlmann Europe.
Major Producers: Shandong Kailong Chemical Industry, Shanti Inorgochem, Shijiazhuang Xinlongwei Chemical, Tianjin Xinxin Chemical, Yixing Weixing Chemical.
Specialized Suppliers: Merck KGaA, Southern Ionics Incorporated, Esseco Group, Hydrite Chemical Co.
Threat of New Entrants (Low): Significant capital requirements and environmental permits for sulfur-based chemical production act as major barriers.
Bargaining Power of Suppliers (Moderate): Suppliers of raw materials (Soda Ash and SO2) have moderate influence, though pricing is largely tied to global commodity trends.
Bargaining Power of Buyers (Moderate to High): Buyers in the water treatment and food sectors are price-sensitive and often purchase in bulk, giving them leverage.
Threat of Substitutes (Moderate): Sodium Metabisulphite is a strong alternative (solid form), but liquid Sodium Bisulphite remains preferred for ease of dosing in large-scale water treatment.
Intensity of Rivalry (High): Competition is primarily based on cost efficiency, distribution network strength, and grade purity.
Strengths: Highly cost-effective reducing agent; globally approved for food use; essential for environmental compliance in water treatment.
Weaknesses: Handling hazards (release of SO2 gas); shelf-life limitations in liquid form (oxidation).
Opportunities: Expansion of the wastewater treatment market in developing economies; growing demand for "clean" chemical synthesis.
Threats: Increasing regulatory scrutiny on sulfites in food products; competition from mechanical water filtration technologies.
Automation in Dosing: Shift toward automated liquid-dosing systems in water treatment plants to optimize chemical usage and safety.
Bio-based Reducing Agents: Initial R&D into bio-derived alternatives, though Sodium Bisulphite remains the current efficiency leader.
Supply Chain Localization: Manufacturers are setting up production hubs closer to major textile and mining clusters to reduce logistical costs.
Drivers: Strict government mandates for zero-liquid discharge (ZLD); growing global population requiring safe drinking water; rise in demand for convenience foods.
Challenges: Volatility in sulfur prices; safety concerns regarding sulfite sensitivity in the food sector; high transportation costs for liquid chemicals.
Raw Material Sourcing: Procurement of Sulfur/Sulfur Dioxide and Soda Ash (Sodium Carbonate).
Manufacturing: Absorbing SO2 into a soda ash solution under controlled pH and temperature.
Quality Control: Purity testing for Food/Technical grade certification.
Logistics: Specialized transport in corrosion-resistant tanks.
End-User: Application in water plants, food factories, or textile mills.
For Manufacturers: Focus on expanding Technical Grade capacity in the APAC region, specifically targeting the burgeoning wastewater treatment sector.
For Investors: Prioritize companies with integrated SO2 capture systems, as they are better insulated from raw material price shocks and meet ESG criteria.
For End-Users: Consider switching to automated dosing systems to reduce waste and ensure compliance with discharge permits.
