From February to March 2025, the domestic sulfuric acid market was supported by increased costs and increased demand, and showed a rapid upward trend overall. In April, the main downstream phosphate fertilizer preparation was basically completed, and the demand support for sulfuric acid was expected to weaken. In addition, the price of sulfur on the raw material side fell, the pressure on the cost side decreased, and the turning point of the downward trend of sulfuric acid prices appeared, and the price fluctuated and weakened. Entering May, the downstream fertilizer industry gradually entered the traditional off-season of demand, and the demand side was insufficiently supported, but the price of raw sulfur rose overall at the beginning of the month due to tight supply and market sentiment, and the cost side supported it again. Affected by the different performance of the comprehensive supply side, the wait-and-see sentiment in the sulfuric acid market was obvious, and the price performance in various places rose and fell, but most regions were still weak, and the average price performance was downward. According to Zhuochuang Information data monitoring, as of May 6, the average daily price of 98% sulfuric acid in the domestic market was 630.31 yuan/ton, a month-on-month decrease of 8.65%.
