Today, the average difference indicator for ammonium sulfate clearly signals a decline, with major Chinese producers collectively lowering their quotations. The current price is at the low end of the 1-year cycle, limiting the room for further decline. Subsequently, it will be necessary to closely monitor the supporting effect of demand-side changes, such as those in compound fertilizers and crop fertilizers.

Three, Conclusions on Trend Directions in China
The price trend is clearly downward, reasons: the changes in the 5-day, 10-day, and 20-day averages compared to yesterday are all negative, which conforms to the rule in the average difference method that "if all three are negative → the price trend is clearly downward"; at the same time, the quotations for industrial-grade ammonium sulfate in Shandong have been adjusted downward, with actual market transactions mainly based on negotiations, and the spot market shows a clear downward trend.
IV. Positional Spatial Reference
Ammonium sulfate 1-year cycle price is at a low level (within the lowest 20% range of the cycle). According to the 5-tier price position rule, a low range indicates limited downward potential. If subsequent demand for compound fertilizers and agricultural fertilizers in China improves, there is a potential for the market to stabilize and rebound.
