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.
Recent Market Dynamics
1. Price Trends
- The domestic market price of sodium bisulfite has recently shown a slight upward fluctuation. As of now, the mainstream quoted price for industrial-grade sodium bisulfite ranges from 1,800 to 2,200 RMB/ton, with premium prices in some regions experiencing a slight increase of approximately 50 to 100 RMB/ton.
- The price for food-grade sodium bisulfite is relatively higher, with mainstream prices ranging from 2,500 to 3,000 RMB/ton. Price fluctuations are minimal, and the overall trend remains stable.
2. Supply Situation
- The operating rate of domestic sodium bisulfite producers remains at a moderate level. Some enterprises have temporarily halted production or reduced output due to environmental inspections and equipment maintenance, leading to a slight decrease in overall market supply.
- Few new production capacities have come online recently, limiting the increase in market supply. In some regions, tightness in available stock has been observed.
3. Demand Situation
- In the industrial sector, sodium bisulfite is widely used in papermaking, textiles, and printing and dyeing industries. As these sectors gradually enter their traditional peak production seasons, demand for sodium bisulfite has increased. Specifically, in the papermaking industry, where it is used as a bleaching agent and dechlorinating agent, demand has shown a steady upward trend.
- Demand in the food sector remains stable. Food-grade sodium bisulfite is used as a preservative and antioxidant in food processing, such as in wine production and dried fruits. Although demand is less affected by seasonality, recent stricter regulatory oversight has led some enterprises to adopt more cautious purchasing strategies, resulting in limited demand growth.
4. Cost Factors
- The main raw materials for sodium bisulfite are soda ash and sulfur. Recently, the market price of soda ash has shown a steady increase with slight fluctuations, while sulfur prices have also risen due to international market influences. This has increased the production cost of sodium bisulfite, providing certain support for product prices.
5. Import and Export Situation
- Imports: China's imports of sodium bisulfite are relatively low, mainly consisting of small quantities of high-end products from neighboring countries to meet specific needs. Import volumes have shown no significant changes recently.
- Exports: With the gradual recovery of international demand, China's exports of sodium bisulfite have increased. However, due to international market competition, the increase in export prices has been limited.
Analysis and Judgment
1. Supply Side: Due to temporary shutdowns for maintenance by some enterprises and the slow rollout of new capacities, it is unlikely that market supply will increase significantly in the short term. The current tightness in stock may persist for some time, exerting upward pressure on prices.
2. Demand Side: The arrival of the peak production season in the industrial sector will drive growth in sodium bisulfite demand, while demand in the food sector remains stable but lacks strong growth momentum. Overall demand is expected to maintain a growth trend, although the growth rate may be constrained by the cautious purchasing attitude in the food industry.
3. Cost Side: Rising raw material prices have increased the production cost of sodium bisulfite. To maintain profit margins, enterprises have a willingness to raise prices. Cost factors will provide strong support for price levels.
4. Import and Export Side: Changes in import volumes are minimal. The increase in export volumes has little impact on domestic market supply. While international competition exerts some pressure on export prices, the overall impact on domestic market prices remains limited.
Forecast
1. Price: It is expected that the domestic market price of sodium bisulfite will continue to show a slight upward trend in the short term. Industrial-grade prices are likely to break through 2,200 RMB/ton, while food-grade prices will fluctuate within the 2,500 to 3,000 RMB/ton range. In the medium to long term, as supply gradually recovers and demand growth stabilizes, the pace of price increases will narrow, but prices will generally remain at a higher level.
2. Supply: As enterprises complete maintenance and new capacities come online gradually, market supply will increase, and the current tightness in stock will ease. However, the growth rate of supply may remain relatively slow.
3. Demand: Industrial demand will continue to grow, while food sector demand will remain stable. Overall demand is expected to remain robust during the traditional peak season, but future demand growth may face certain pressures.
4. Market Trend: Considering supply, demand, and cost factors, the sodium bisulfite market is expected to maintain a tight balance between supply and demand in the short term, with prices showing stability with an upward bias. In the medium to long term, the market will gradually return to rationality, price fluctuations will decrease, and market trends will stabilize.
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.
