Chempricehub Analysis of Ammonium Sulfate, Bull-Bear Score: 1. Shandong Luxi Chemical's ex-factory price for caprolactam-grade ammonium sulfate increased by 20 yuan per ton to 1,740 yuan per ton, indicating tight market supply or increased downstream demand, which directly supports the spot price of ammonium sulfate. The fact that actual transactions are primarily negotiated reflects enhanced market confidence, but the limited increase (approximately 1.15%) and the absence of significant supply-demand events driving the change lead to an assessment of moderate positive impact.
