Business Society’s DOP Trend Analysis for September 15, 2026: Clearly Upward

ECHEMI 2026-09-15

As of September 14, 2026, the spot price of the plasticizer DOP in China has continued to rise for several days. The prices of upstream raw materials, such as 2-ethylhexanol and phthalic anhydride, have also increased, providing strong cost support. Indicators show that the current DOP price is in a clear upward trend, but the price is already at a high level for the past year, and the room for further increases is relatively limited.

I. Table of Mean Difference Changes

Mean Difference Indicator Today's Value (2026.09.14) Yesterday's Value (2026.09.13) Direction of Change
5-day Mean Difference D5 78.34 58.33 +
10-day Mean Difference D10 210.83 206.67 +
20-day Mean Difference D20 257.92 243.75 +

II. Signal State Determination

The current three mean differences have all increased compared to the previous day, meeting the clear upward signal criteria of the mean difference method in China.

III. Trend Direction Conclusions

The current DOP price trend is clearly upward. Reason for this determination:

The 5-day, 10-day, and 20-day moving averages all showed the same direction of change as the previous day, and all were positive, meeting the clear upward-trend criteria stipulated by the moving-average difference method.

In the past week, prices quoted by major Chinese DOP producers have been continuously raised, and the actual transaction prices for spot goods have also increased accordingly.

The prices of upstream raw materials, such as 2-ethylhexanol and phthalic anhydride, have risen simultaneously, providing strong support on the cost side.

4. Spatial Reference

The prices for the 60-day, 3-month, and 1-year cycles are all in the 5th percentile (high range), meaning they are in the top 20% of their respective one-year highs, with relatively limited room for further increases.
