Guoxin Securities·2025-04-03 01:25Investment Rating - The report maintains an "Outperform" rating for the potassium and phosphorus chemical industries [5]. Core Views - The potassium fertilizer supply and demand remain tight, with international prices rising due to increased demand during the spring farming season. Domestic potassium chloride prices have increased by 9.8% to 2800 CNY/ton in March 2025 [1][47]. - The phosphorus chemical industry is expected to maintain a high price level for phosphate rock due to declining grades and increasing extraction costs, with the market price for 30% grade phosphate rock remaining around 900 CNY/ton for over two years [2][52]. Summary by Sections Potassium Fertilizer - Potassium is essential for crop growth, with potassium chloride being the dominant form used in agriculture, accounting for over 95% of potassium fertilizer usage [14]. - China is the largest consumer of potassium fertilizer, with an import dependency exceeding 60%. In 2024, China's potassium chloride production is projected to be 5.5 million tons, a decrease of 2.7% year-on-year, while imports are expected to reach a record high of 12.63 million tons, up 9.1% [1][28]. - The report highlights the resource scarcity of potassium, with major production concentrated in a few countries, leading to a tight global supply situation [15][22]. Phosphorus Chemical Industry - The phosphorus chemical industry's performance is closely tied to phosphate rock prices, which are expected to remain high due to supply constraints and increasing demand from new applications like lithium iron phosphate [2][52]. - As of March 31, 2025, the market price for 30% grade phosphate rock in Hubei is 1040 CNY/ton, while in Yunnan it is 950 CNY/ton, both stable compared to the previous month [2][52]. - The report notes that the domestic phosphorus fertilizer prices have increased due to rising production costs, with diammonium phosphate prices at 3519 CNY/ton, reflecting a 6.44% increase month-on-month [3][51]. Investment Recommendations - The report recommends focusing on companies with rich phosphate reserves and strong market positions, such as Yuntianhua and Xingfa Group, while also suggesting attention to companies like Hubei Yihua and Yuntu Holdings that are improving their phosphate self-sufficiency [4][50]. - For potassium fertilizer, Ayat International is highlighted as a key investment opportunity, with projected production of 2.8 million tons in 2025 and 4 million tons in 2026 [4][50].
