Today, the spot market prices for DOP in China continued to rise. The prices of upstream raw materials, such as 2-ethylhexanol and phthalic anhydride, are at their highest levels in nearly one year, providing strong support on the cost side. From the perspective of the average difference indicator, the current price is in a range that is more likely to consolidate and retrace slightly. The prices have already reached their highest levels in nearly one year, and the room for further increases is relatively limited. It is necessary to pay attention to the follow-up demand from the downstream PVC plasticizer market.
Note: The latest available data currently dates back to September 15, 2026. It is recommended to refer to real-time data for the most up-to-date information.
I. Table of Mean Difference Changes
| Mean Difference Indicator | Today (2026.09.15) Value | Yesterday (2026.09.14) Value | Direction of Change |
|---|---|---|---|
| 5-day Mean Difference (D5) | 150 | 78.34 | + |
| 10-day Mean Difference (D10) | 192.5 | 210.83 | - |
| 20-day Mean Difference (D20) | 276.25 | 257.92 | + |
II. Signal State Determination
The current combination of mean difference change signs is (+, -, +), corresponding to a pullback signal (slightly bullish).
III. Trend Direction Conclusions
The current price trend is oscillating (with a bullish bias). Reason: The changes in the 5-day, 10-day, and 20-day moving averages compared to the previous day are not completely consistent, which does not meet the criteria for a clear upward or downward trend. This is a bullish retracement within an oscillating range.
IV. Positional Spatial Reference
Prices for the 60-day, 3-month, and 1-year cycles are all at the 5th tier (high level), with limited room for further increases. Subsequent attempts to chase higher prices carry relatively high risks.
V. Today's Spot Market Quotation in China
Shandong Shengfeng Chemical's DOP execution price is 10,605 CNY/ton, with the quotation rising by 100 CNY/ton, and the actual transaction price has also increased.
Dongying Yimeide Chemical's DOP ex-factory quotation is 10,650 CNY/ton, with an increase of 300 CNY/ton, and the actual transaction price has risen.
Zhenjiang Liancheng Chemical's DOP ex-factory price is 10,750 CNY/ton, with an increase of 50 CNY/ton.
The current mainstream manufacturers in China are operating at normal capacity, with quotations generally increasing and a positive trading atmosphere.
VI. Upstream and Downstream Fundamental References
Upstream: Both isooctanol and phthalic anhydride prices today are at their highest levels in nearly one year, providing strong cost support for DOP.
Downstream: Primarily used as a PVC plasticizer, the pace of procurement by downstream demanders will directly influence the price trend of DOP.
