Phosphorous acid Market share- How big is the Phosphorous acid market?

China and the United States are the leading exporters of phosphorous acid (CAS 13598-36-2), accounting for a substantial majority of global shipments, while India, South Korea, and Germany represent the largest importers. Phosphorous acid prices have remained relatively stable amid steady demand from agrochemical and pharmaceutical sectors. Exports from China have grown modestly over the past two years, while U.S. exports have held steady, and Indian imports have increased notably—reflecting expanding domestic production of crop protection chemicals.

Phosphorous acid Market Analysis

Market Dynamics Intelligence on Phosphorous AcidI. Price Trends1. **Domestic Market**: Recently, domestic phosphorous acid prices have shown a stable but slightly upward trend. Mainstream transaction prices have fluctuated in the range of 9,500-10,500 RMB/ton, with some high-end quotes exceeding 11,000 RMB/ton, representing an increase of approximately 3%-5% compared to the beginning of the month.2. **International Market**: Asian FOB prices have remained stable at 1,400-1,500 USD/ton, while European CIF prices are approximately 1,600-1,700 USD/ton. International prices have experienced minimal fluctuations due to exchange rate and logistics cost impacts.II. Supply and Demand Relationship1. **Supply Side**: - The operating rate of major domestic production enterprises has been maintained at 75%-80%. Some enterprises have reduced production due to environmental restrictions or equipment maintenance, leading to an overall supply decrease of approximately 5% compared to the previous month. - Import volumes increased by 8% month-on-month, primarily from India and South Korea. However, delayed arrival times have caused short-term supply tightness.2. **Demand Side**: - Downstream pesticide industries have entered their traditional peak season, with phosphorous acid demand increasing by approximately 10%, particularly driven by strong demand for herbicide raw materials such as glyphosate. - Demand from the food additive and flame retardant industries remains stable, but procurement volume growth is limited due to cost pressures.III. Cost and Profitability1. **Raw Material Costs**: Yellow phosphorus prices have risen to 25,000-26,000 RMB/ton due to power restrictions in the southwest region. Liquid chlorine prices fluctuate significantly due to regional supply and demand differences (800-1,200 RMB/ton), pushing up phosphorous acid production costs by approximately 6%.2. **Profit Margins**: The industry's average gross margin has compressed to 12%-15%. Some small and medium-sized enterprises have suspended quotes due to cost pressures, resulting in a reduction of low-priced market supplies.IV. Inventory and Logistics1. **Inventory Levels**: Production enterprise inventory turnover days have shortened to 10-12 days. Trader inventories are low, and the willingness to replenish inventory has increased.2. **Logistics Impact**: Domestic road transportation costs have increased by 5%-8% due to rising oil prices. Port congestion has caused import cargo arrivals to be delayed by approximately 7-10 days.V. Policy and Environmental Factors1. Domestic environmental policies continue to tighten. Some enterprises have had production restricted due to non-compliance with exhaust emission standards, which is expected to impact annual production capacity by approximately 30,000 tons.2. Expectations for adjustments to export tax rebate policies are rising, prompting some enterprises to sign contracts in advance to lock in profits.Analysis and Judgment1. **Short-term Driving Factors**: High-level yellow phosphorus prices, peak-season demand from downstream pesticide industries, and the combination of supply-side production cuts and import delays have collectively pushed up phosphorous acid prices.2. **Medium-term Risk Points**: If yellow phosphorus prices decline due to the alleviation of power supply issues in the southwest region, or if downstream pesticide industries complete their stockpiling in advance, prices may face downward pressure.3. **Competitive Landscape**: Industry concentration is relatively low, and small and medium-sized enterprises have weak bargaining power. Lagged cost transmission may lead to increased price volatility.Forecast1. **Price Trend**: Over the next two weeks, phosphorous acid prices are expected to maintain a stable upward trend, with mainstream transaction prices potentially breaking through 11,000 RMB/ton, although the rate of increase is expected to narrow to within 2%.2. **Supply and Demand Changes**: By late September, as import cargo arrives and some enterprises resume production, the supply tightness will ease, and prices may see a slight pullback to the 10,500-10,800 RMB/ton range.3. **Key Focus Areas**: Monitor yellow phosphorus price trends, downstream pesticide industry operating rates, the enforcement intensity of environmental policies, and changes in export policies.

About Phosphorous acid

Phosphorous acid is a white, crystalline solid at room temperature, hygroscopic and highly soluble in water, with a melting point of approximately 73.6 °C and decomposition above 200 °C. It is an inorganic oxyacid of phosphorus, specifically a phosphonic acid (H₃PO₃), and exists predominantly as the tautomeric phosphonic acid form in solution. It serves primarily as a key intermediate in the synthesis of phosphonates and organophosphorus compounds, including flame retardants, scale inhibitors, and agricultural chelating agents. Its main industrial applications are in water treatment chemicals, metal surface treatment formulations, and as a precursor to glyphosate and other phosphonate-based agrochemicals.

Phosphorus acid is used to prepare phosphite salts. It is usually sold as a 20% aqueous solution.
