Germany and the United States are the leading exporters of iron sesquisulfate, accounting for the largest shares of global shipments in recent years, while India, Brazil, and South Africa represent the most significant importers. Iron sesquisulfate prices have remained relatively stable amid modest volume fluctuations across key trade corridors. Import volumes have shown gradual growth in emerging agricultural markets, particularly in Latin America and Southern Africa, reflecting increased demand for iron-based soil amendments and water treatment applications.
Market Dynamics Report on Polyferric Sulfate (PFS)
I. Price Trends
1. Domestic Market:
- East China: The price of solid PFS (content ≥28%) remains stable at 2,200–2,400 RMB/ton. Some enterprises have slightly raised their quotations to 2,450 RMB/ton due to rising costs of iron salt raw materials.
- South China: Prices are maintained at 2,300–2,500 RMB/ton. Driven by demand from the downstream water treatment industry, local transaction prices have risen to as high as 2,550 RMB/ton.
- North China: The price range is 2,100–2,300 RMB/ton. Due to stricter environmental inspections, some small-scale plants have halted production, leading to a slight tightening of supply; however, overall price fluctuations remain limited.
2. International Market:
- Southeast Asia: Chinese export quotations are in the range of $320–$350/ton (FOB). Due to declining shipping costs, some order prices have decreased slightly by $5–$10/ton.
- India: Import prices remain stable at $300–$330/ton (CFR), with no significant fluctuations, impacted by weak domestic demand.
II. Supply and Demand Dynamics
1. Supply Side:
- Domestic capacity utilization stands at approximately 75%, an increase of 3 percentage points from the previous month, primarily due to the resumption of operations by enterprises that were previously under maintenance.
- Raw material prices for sulfuric acid and iron salts remain high, increasing cost pressures for some enterprises, but large-scale production cuts have not yet occurred.
- Continuous tightening of environmental policies has led to the shutdown of some small plants in North and East China due to non-compliance with emission standards, causing localized tightening of regional supply.
2. Demand Side:
- Demand from the downstream water treatment industry remains stable, with procurement volumes in municipal sewage treatment and industrial wastewater treatment increasing by 5%–8% month-on-month.
- Demand for PFS in the paper and printing/dyeing industries continues to grow due to stricter environmental requirements, although the growth rate has slowed due to seasonal factors.
- The export market is driven by demand in Southeast Asia, with order volumes increasing by 10% month-on-month. However, demand in India has contracted due to currency depreciation and adjustments in import policies.
III. Costs and Profits
1. Raw Material Costs:
- Sulfuric acid prices continue to rise due to tight supply, with the price of 98% sulfuric acid in East China breaking through 500 RMB/ton, an 8% month-on-month increase.
- Iron salt prices (e.g., ferrous sulfate) have increased slightly by 3%–5%, influenced by fluctuations in iron ore prices.
2. Profit Margins:
- The industry average gross profit margin is approximately 15%–18%, a decrease of 2 percentage points from the previous month, mainly due to profit compression caused by rising raw material costs.
- Large-scale enterprises maintain gross profit margins above 20% due to procurement cost advantages, while the profit margins of small plants are further compressed.
IV. Analysis and Judgment
1. Short-Term Driving Factors:
- High raw material costs and tightening environmental policies will support PFS prices; however, limited acceptance of high prices by downstream customers will restrict price increases.
- The export market, driven by growing demand in Southeast Asia and declining shipping costs, may become the primary driver for short-term price increases.
2. Risk Factors:
- Volatility in sulfuric acid prices: If supply tensions ease and prices fall, it may lead to a decrease in PFS prices.
- Seasonal weakening of downstream demand, particularly reduced water treatment demand in northern regions during winter, may suppress price increases.
V. Price Forecast
1. Domestic Market:
- Next Week: Prices are expected to remain stable with an upward bias. Main transaction prices in East and South China may rise to 2,450–2,550 RMB/ton, while prices in North China may see slight increases to 2,250–2,350 RMB/ton due to tightened supply.
- Next Month: If raw material costs remain high, prices may fluctuate within a range. However, the seasonal weakening of demand may constrain further upside potential.
2. International Market:
- Southeast Asia: Chinese export quotations are expected to remain stable at $320–$350/ton, with local orders potentially rising slightly to $355/ton due to increased demand.
- India: Impacted by weak domestic demand and currency depreciation, import prices are expected to remain at $300–$330/ton, with no significant upward momentum.
Iron sesquisulfate (CAS 35139-28-7) is a yellow to brownish-yellow crystalline solid, typically supplied as a hydrated powder or granular material; it is non-volatile, odorless, and decomposes before melting. It is an inorganic iron(III) salt, specifically the sulfate of ferric iron with a nominal Fe₂(SO₄)₃ stoichiometry, often existing in hydrated forms. Industrially, it serves primarily as a coagulant and flocculant in water and wastewater treatment, leveraging its ability to hydrolyze and form insoluble iron(III) hydroxide precipitates. It is also employed as a precursor in the production of iron oxide pigments and as a catalyst or reagent in select metallurgical and ceramic processes. Its applications are concentrated in water treatment, pigment manufacturing, and specialty inorganic synthesis.
