Hualu Hengsheng has raised the ex-factory price of ammonium sulfate by 10 yuan/ton, with caprolactam-grade bulk material quoted at 1,100 yuan/ton and power plant-grade at 985 yuan/ton. This indicates a possible tightening of market supply or an increase in demand, providing favorable support for the spot price of ammonium sulfate. The price increase is relatively small (approximately 1%), reflecting a moderate improvement rather than a significant change, which is generally considered a positive development. The fact that actual transaction prices are subject to negotiation suggests increased market activity, but attention should be paid to the subsequent supply-demand balance.
