According to a research report published by Spherical Insights and Consulting, The Global Sodium Bisulfite Market Size was worth around USD 0.75 Billion in 2024 and is Predicted to Grow to around USD 1.18 Billion by 2035 with a Compound Annual Growth Rate (CAGR) of 4.21% from 2025 to 2035. The global market for sodium bisulfite is expanding due to the increasing water treatment needs, growing food preservation demands and industrial growth in pulp and paper, and textile sectors. The Asia-Pacific region experiences increased demand owing to its industrial growth and environmental control measures.

Market Overview

The global sodium bisulfite or sodium hydrogen sulfite exists as a white crystalline water-soluble inorganic compound, which scientists use to create reducing agents, preservatives and antichlor substances. Its main uses involve dechlorinating wastewater from both municipal and industrial sources, bleaching pulp for paper production, and serving as an antioxidant in food and beverages and pharmaceuticals. The market operates because of environmental regulations that mandate wastewater treatment, together with industrial growth and customers who prefer processed foods with high preservative content.

The European Commission launched its Action Plan for the Chemicals Industry in July 2025 to enhance competitiveness through its chemical industry initiative. The initiative addresses three problems, including high energy costs, unfair competition, and weak demand, by establishing two programs that support sodium bisulfite manufacturers, the Critical Chemical Alliance and the Affordable Energy Action Plan. The adoption of eco-friendly high-purity formulations creates new growth opportunities in developing markets. The market receives strong support because the pulp and paper industry depends on its ability to provide bleaching solutions. The global market is controlled by key companies, which include INEOS Calabrian Corp., BASF SE, Evonik Industries AG, Aditya Birla Chemicals, Solvay S.A., Esseco USA LLC and Grillo-Werke AG, with Asia-Pacific countries leading in both production and consumption.

Restraining Factors

Health risks from exposure, which cause respiratory irritation, together with people using alternative water treatment technologies, which include UV and RO filtration systems, prevent the global sodium bisulfite market from growing. The market faces limitations due to strict environmental regulations and supply chain issues, and the presence of sodium metabisulfite as a substitute for sodium bisulfite creates obstacles to growth.

Market Segmentation

The sodium bisulfite market share is classified into grade and end-use. 

• The industrial grade segment dominated the market in 2024, approximately 68% and is projected to grow at a substantial CAGR during the forecast period.

Based on the grade, the Global Sodium Bisulfite Market Size is divided into industrial grade, food grade, and pharmaceutical grade. Among these, the industrial grade segment dominated the market in 2024 and is projected to grow at a substantial CAGR during the forecast period. The industrial segment of sodium bisulfite covers high-volume applications in water treatment, chemical processing, pulp and paper and textile industries. The company leads the market because customers widely choose its product, which combines technical purity with cost-effective features. The formulations deliver dependable results through their dechlorination, oxygen scavenging, bleaching and reduction capabilities, which provide cost-effective bulk procurement solutions to large-scale operations.

• The water treatment segment accounted for the highest market revenue in 2024, approximately 42% and is anticipated to grow at a significant CAGR during the forecast period.

Based on the end-use, the Global Sodium Bisulfite Market Size is divided into water treatment, pulp & paper, food & beverages, textiles, pharmaceuticals, and other. Among these, the water treatment segment accounted for the highest market revenue in 2024 and is anticipated to grow at a significant CAGR during the forecast period. The water treatment segment dominates the sodium bisulfite market because sodium bisulfite functions as an essential component in municipal dechlorination and industrial wastewater treatment and boiler water conditioning throughout the world. The market leadership of the company depends on three factors, which include the development of municipal infrastructure, the implementation of stricter discharge regulations and the increasing industrial adoption of zero liquid discharge systems that require reliable chemical treatment solutions.
