On August 26, 2026, the spot price of DOP in China slightly declined, with mainstream manufacturers generally reducing their quotes by 50-100 CNY/ton. Based on the analysis of the average difference method, the current DOP market is in a deep correction phase at a high level, and the overall trend is characterized by fluctuating operations. The cost side is still supported by upstream raw materials, but downstream demand is insufficient. In the short term, the room for price increases is limited, and there is pressure for adjustments at high levels.
I. Table of Mean Difference Changes
| Average Difference Type | Value as of August 26, 2026 | Value as of August 25, 2026 | Direction of Change |
|---|---|---|---|
| 5-day Average Difference (D5) | 28.33 | 88.34 | - |
| 10-day Average Difference (D10) | 126.67 | 162.5 | - |
| 20-day Average Difference (D20) | 224.59 | 206.25 | + |
II. Signal State Determination
The current deviation change symbol combination is (－, －, ＋), which belongs to a deep correction (biased bearish, corrective nature) signal.
III. Conclusion on Trend Directions
The current price trend is judged to be fluctuating. The reason is that the change directions of the 5-day, 10-day, and 20-day moving averages compared to the previous day are not entirely consistent, which meets the criteria for a fluctuating market. Specifically, it is characterized as a bearish pullback from a high level.
IV. Positional Spatial Reference
The DOP price is in the 5th tier (high level) for both the 60-day and 3-month cycles, and in the 4th tier (mid-to-high level) for the 1-year cycle. Overall, the price has entered a high-range territory, leaving limited room for further upward movement and increasing the likelihood of a pullback and correction from the current high levels.

VI. Fundamental Supplement
Cost side: Both upstream iso-octanol and phthalic anhydride remain at high price levels, providing strong cost support for DOP.
Supply side: Mainstream plasticizer manufacturers in China are operating normally, and the overall supply is stable.
On the demand side: Downstream PVC plasticizer demand has been relatively weak, and market trading activity remains subdued. On August 26, mainstream manufacturers such as Shandong Shengfeng, Zhenjiang Liancheng, and Zhejiang Hongbo all lowered their DOP quotations by 50-100 CNY per ton.
