On May 18, the sulfuric acid market in Henan was operating stably. As of now, the ex-factory transaction price of 98% of smelted acid in Henan is between 1 and 50 yuan/ton. Recently, the shipment of acid factories in the zone is still good. After continued price cuts in the early stage, the shipment of sulfuric acid has improved. However, as the downstream phosphate fertilizer and titanium dioxide markets are in a downturn, most purchases remain in demand, and there is no obvious benefit in the market., acid prices are unlikely to improve. In the subsequent period, some sulfuric acid units in the area were stored and repaired, and the acid price in the area stopped falling. However, the subsequent demand situation remains to be seen and seen, and it is expected that the short-term rise and fall will be in a dilemma.
