China and the United States are the leading exporters of sodium bisulfite, accounting for a substantial share of global shipments, while India, Vietnam, and Mexico are among the top importers, driven by demand in food preservation, water treatment, and pharmaceutical manufacturing. Recent data indicates relative stability in trade volumes through 2023–2024, with modest upward pressure on sodium bisulfite prices amid tightening environmental regulations on sulfur-based chemical handling in key exporting regions.
Sodium Bisulfite: Recent Commodity Market Intelligence, Analysis, and Forecast
I. Market Intelligence
Price Dynamics
- Industrial-grade sodium bisulfite: Prices vary across brands and origins. For example, Jiaen Chemical (Shandong) Co., Ltd. quotes RMB 3,800 per metric ton in Fujian Province; Suzhou Shangma Chemical Technology Co., Ltd. quotes RMB 4,400 per metric ton for its domestic product in Jiangsu Province/Suzhou City; Shandong Jinshengrun Chemical Co., Ltd. quotes RMB 3,300 per metric ton for its domestic product in Shandong Province/Jinan City; and Jinan Aoxin Chemical Co., Ltd. quotes RMB 3,500 per metric ton for its domestic product in Shandong Province/Jinan City.
- Food-grade sodium bisulfite: Prices are generally higher, with Hubei Qibajiu Chemical Co., Ltd. quoting RMB 9,800 per metric ton in Hubei Province/Wuhan City.
- Special-specification products: Certain batches or specifications of industrial-grade sodium bisulfite from Hubei Qibajiu Chemical Co., Ltd. are quoted as low as RMB 1,800 per metric ton.
Supply-Demand Situation
- Supply: Overall market supply capacity has recently declined, as tightening environmental regulations have constrained production at some small- and medium-sized enterprises (SMEs), leading to a contraction in market supply.
- Demand:
- Traditional sectors: Demand remains stable in pharmaceuticals, food, and other established applications. In particular, demand in the pharmaceutical sector—driven by rapid growth in vaccine development and biopharmaceutical manufacturing—has shown steady growth, given sodium bisulfite’s role as an antioxidant.
- Emerging sectors: Demand from new application areas, especially new energy, is growing rapidly; its share of total applications reached 5.7% in 2023, with a compound annual growth rate (CAGR) of 48%.
Industry Developments
- Standardization: The industry standard system for sodium bisulfite continues to mature in 2025, with clearly defined standards tailored to different application scenarios. These refined technical specifications establish clear quality thresholds. For instance, food additive-grade sodium bisulfite complies with GB 25590–2010; chemical reagent-grade sodium bisulfite follows HG/T 3492–2003; and industrial-grade sodium bisulfite adheres to HG/T 3814–2006.
- Technological Advancement: Adoption of novel preparation technologies—including membrane separation, catalytic oxidation, and bipolar membrane electrodialysis—is increasing. These innovations reduce energy consumption per unit output and enhance resource utilization of by-products. Bipolar membrane electrodialysis, in particular, shortens production cycles and lowers residual free alkali content.
II. Analysis and Assessment
Price Trend
- Short term: Given constrained supply amid stable demand in traditional sectors and rapidly expanding demand in emerging sectors, prices are expected to remain firm and trend upward in the near term—especially for food-grade and premium industrial-grade products.
- Long term: As advanced production technologies become more widespread and production costs decline, coupled with intensifying market competition, prices may gradually stabilize or slightly decline overall; however, premium-product pricing will likely remain elevated.
Supply-Demand Relationship
- Supply side: Ongoing tightening of environmental regulations will compel manufacturers to increase environmental investments and upgrade production processes. Concurrently, some SMEs may exit the market, further reducing overall supply.
- Demand side: Demand in traditional sectors will continue growing steadily, while demand from emerging sectors will serve as a key growth driver. Rising downstream requirements for product quality and environmental performance will fuel increasing demand for high-end sodium bisulfite products.
Industry Development Trends
- Green Transformation: Driven by environmental regulation and technological innovation, the sodium bisulfite industry is shifting toward greener operations. Advanced preparation methods are progressively replacing conventional processes, thereby reducing pollutant emissions and enhancing resource efficiency.
- Premiumization: Escalating downstream demands for superior quality and performance are prompting manufacturers to increase R&D investment and develop high-end products—for example, electronic-grade sodium bisulfite—whose market share is projected to rise steadily.
- Consolidation: Intensifying competition will drive industry consolidation, with large enterprises gaining dominant market positions via mergers, acquisitions, and strategic restructuring. SMEs will face mounting pressure and must seek survival through differentiation and specialization.
III. Forecast
Market Size
- The global sodium bisulfite market is projected to grow continuously over the next several years, reaching USD 2.53 billion by 2028, representing a CAGR of 6.2%. The Chinese market is forecast to reach RMB 19.5 billion in 2025—a 5.4% year-on-year increase—and outpace the global average growth rate.
Price Volatility
- Price fluctuations will be influenced by multiple factors—including raw material costs, environmental policy adjustments, and demand dynamics. Prices are expected to experience more frequent short-term volatility, but the overall trend will remain stable or exhibit modest upward movement.
Industry Structure
- The industry structure will gradually optimize, with large enterprises assuming leadership roles. SMEs will pursue niche markets and specialized development strategies to maintain competitiveness. Meanwhile, collaboration and integration within the industry will deepen, fostering a more robust, integrated industrial and supply chain ecosystem.
Sodium bisulfite is a white crystalline solid or powder, typically odorless or with a faint sulfur dioxide odor, and highly soluble in water; it decomposes before melting and releases SO₂ upon heating or acidification. It is an inorganic salt and reducing agent, commonly formulated as NaHSO₃ (often as a hydrated or aqueous solution). It serves primarily as a preservative, antioxidant, and sulfonating agent in industrial processes, and is widely employed as a key intermediate in the synthesis of organic sulfonates, dyes, and pharmaceuticals. Typical application areas include food preservation (as a processing aid), water treatment (for chlorine removal), pulp and paper bleaching, and the production of dyes, leather tanning agents, and certain agrochemical formulations.
1. Used as reducing agent, food preservatives and bleach.2. Used for the bleaching of cotton fabric and organic substance. Used as reducing agents in dyes, paper, leather, chemical synthesis and other industries. Used for the production of analgin and aminopyrine intermediates in pharmaceutical industry. Used as bleach, preservatives, and antioxidants of food grade products. 3. Sodium bisulfite is reduction bleach allowed to use in China. It has bleaching effect on food and has a strong inhibitory effect on the oxidase within plant foods. It can be used for candied fruit, glucose, sugar, rock candy, caramel, candy, liquid glucose, dried fruit, dried vegetables, vermicelli, bamboo shoots, mushrooms and mushroom cans in provisions of our country, with a maximum use of 0.45g/kg; it can also be used for potato starch with a maximum use amount of 0.2g/kg and a maximume residual amount (in terms of SO2) of less than 0.03 g/kg.4. Used as reductants in analysis and also as bleach and bacterial inhibitors5. Used as reducing agent, antiseptic, disinfectant and bleach.
