China and the United States are the leading exporters of sodium phosphite, collectively accounting for the majority of global shipments, while India, South Korea, and Germany represent the largest importers. Sodium phosphite prices have remained relatively stable amid steady cross-border flows. Export volumes from China increased modestly in 2023–2024, while Indian imports rose by approximately 12% year-on-year, signaling growing regional demand in agrochemical applications.
Market Dynamics Report on Trisodium Phosphate (TSP)
I. Price Trends
1. Domestic Market: In recent days, the price of trisodium phosphate in the domestic market has shown a slight upward fluctuation. The average market price in mainstream regions has increased by approximately 2%-3% compared to the previous month. In some areas with tight supply, the price increase has been slightly higher, reaching around 5%.
2. International Market: International market prices remain relatively stable. However, influenced by fluctuations in the US dollar exchange rate and rising international logistics costs, import costs have increased, leading to slight price hikes in quotes from some importers.
II. Supply Situation
1. Capacity Utilization: The capacity utilization rate of domestic trisodium phosphate producers remains between 75% and 80%. Some enterprises have temporarily halted production due to environmental inspections or equipment maintenance, resulting in a slight tightening of supply.
2. Inventory Levels: Inventories at major production enterprises are at low levels, and traders' inventories are also generally low, indicating a tight overall market supply.
3. Import Situation: Import volumes have decreased compared to previous periods, primarily due to tight international supply and rising logistics costs, which have reduced the purchasing willingness of importers.
III. Demand Situation
1. Downstream Industry Demand:
- Detergent Industry: As one of the primary downstream sectors for trisodium phosphate, the detergent industry maintains stable demand. However, due to environmental policies, some enterprises are shifting to more eco-friendly alternatives, limiting demand growth.
- Water Treatment Industry: Demand for trisodium phosphate in the water treatment sector continues to grow, particularly in industrial wastewater treatment, where demand remains substantial.
- Food Industry: Demand for food-grade trisodium phosphate is stable but accounts for a relatively small proportion of the total market.
2. Seasonal Factors: With the onset of winter, water treatment demand in northern regions has increased, driving up the demand for trisodium phosphate.
IV. Cost Factors
1. Raw Material Costs: The main raw materials for trisodium phosphate are phosphoric acid and sodium hydroxide. Recently, phosphoric acid prices have risen slightly, while sodium hydroxide prices remain stable, leading to a slight increase in overall production costs.
2. Energy Costs: Fluctuations in coal, natural gas, and other energy prices have had limited impact on production costs. However, logistics costs have increased due to rising oil prices.
V. Policy and Environmental Impact
1. Environmental Policies: Environmental regulations continue to tighten, causing some small enterprises that do not meet environmental standards to suspend operations for rectification, further reducing market supply.
2. Export Policies: Export policies remain stable, but changes in international market demand significantly impact export volumes.
VI. Analysis and Judgment
1. Short-term: Affected by tight supply and growing demand, trisodium phosphate prices are expected to continue a slight upward trend in the short term.
2. Medium-term: After the peak winter demand for water treatment subsides, the rate of price increases may slow down, but prices are likely to remain at elevated levels overall.
3. Long-term: If environmental policies continue to tighten and some small enterprises exit the market, leading to increased industry concentration, prices may rise further.
VII. Forecast
1. Price Forecast: Over the next month, the average market price of trisodium phosphate may rise to approximately XX CNY/ton, with an increase of about 2%-4%.
2. Supply and Demand Forecast: On the supply side, as some enterprises resume production, the tight supply situation will ease somewhat. On the demand side, demand from the water treatment industry will continue to grow, while demand from the detergent industry may weaken due to the impact of substitutes.
3. Risk Factors: Attention should be paid to the impact of international market price fluctuations, changes in raw material costs, and adjustments in environmental policies on the market.
Sodium phosphite is a white, crystalline, hygroscopic solid with no characteristic odor and low volatility; it decomposes before melting and is highly soluble in water. It is an inorganic phosphorus compound, specifically the sodium salt of phosphorous acid (H₃PO₃). Sodium phosphite serves primarily as a reducing agent and a key intermediate in the synthesis of organophosphorus compounds, including flame retardants and stabilizers. Its principal industrial applications are in agrochemicals—particularly as a fungicide active ingredient and plant health enhancer—and in water treatment formulations for corrosion and scale inhibition. It is also used in electroless nickel plating baths and as a precursor in the production of specialty phosphites for polymer stabilization.
