This analysis of the DOP spot price is based on the latest monitoring data as of October 9, 2026, and uses a mean difference analysis framework to determine that the current DOP price is in a clear upward trend. Major Chinese manufacturers have generally increased their ex-factory quotes by 100-150 CNY per ton. However, the price over a one-year cycle is already at a high level, and the room for further increases is limited. Participants in the upstream and downstream of the industry chain should closely monitor the price fluctuations of upstream raw materials such as 2-ethylhexanol and phthalic anhydride, as well as changes in the demand for downstream PVC plasticizers.
