This issue’s DOP spot price daily report is compiled based on the latest average deviation indicators, supply-demand conditions across the industrial chain, and price adjustment data from manufacturers. As of September 13, 2026, DOP prices remain at high levels. The average deviation signal indicates that the market is in a strong, consolidating, and bullish phase. Upstream raw materials such as phthalic anhydride and iso-octanol are also trading at high levels, providing cost support. Recently, mainstream manufacturers have continuously raised their factory prices; therefore, it is crucial to closely monitor the strength of downstream demand under these elevated price levels.
Data Explanation
The most recent available data is up to September 13, 2026. It is recommended to refer to real-time data.
1. Mean Difference Change Table
| Average Difference Type | Value on 2026-09-13 | Value on 2026-09-12 | Direction of Change |
|---|---|---|---|
| 5-day Average Difference (D5) | 58.33 | 128.33 | - |
| 10-day Average Difference (D10) | 206.67 | 187.5 | + |
| 20-day Average Difference (D20) | 243.75 | 235.83 | + |
2. Signal Status Judgment
The current average difference change combination is (－, ＋, ＋), which belongs to a strong consolidation (biased towards bullish) signal.
3. Trend Direction Conclusion
The current DOP price trend is volatile but slightly strong. Reason: The changes in the three averages compared to the previous day are not entirely consistent, which does not meet the criteria for a clear upward or downward trend, thus the main trend is judged as volatile; combined with the bullish signal attributes (－, ＋, ＋), there is still support for a short to medium-term upward trend, and overall it shows a characteristic of high-level strong consolidation.
4. Positional Spatial Reference
Prices for the 60-day, 3-month, and 1-year cycles are all in the 5th tier (high-range), with relatively limited upside potential. Investors should be vigilant about the risk of a high-level pullback.
5. Fundamental Supplement
From September 8 to 11, 2026, the factory prices of major DOP producers in China continuously increased, with the price increase per ton ranging from 50 to 300 yuan. The overall facility utilization rate in the industry remained at a normal level. During the same period, the prices of upstream raw materials, such as phthalic anhydride and 2-ethylhexanol, were also high, providing strong support on the cost side. The downstream demand was mainly concentrated in the PVC plasticizer sector, with the current demand being stable.
