During this period (October 30–November 5, 2026), the average weekly production gross margin for sample DOTP enterprises in Zhejiang Province, China, reached RMB 559/ton. The weekly average theoretical profit continued to rise, increasing by RMB 248/ton compared to the previous period, representing a week-on-week growth of 79.74%. Tight spot supply in the local region supported low market prices, and since the increase in the average DOTP price exceeded the rise in costs, the theoretical profit margins for enterprises expanded further throughout the week. Currently, industry-wide theoretical profit margins remain ample.
Key data points for calculating the average weekly profit include: the reference weekly delivered price for octanol in Zhejiang was RMB 10,390/ton, and the reference weekly ex-factory price for PTA (the other raw material) was RMB 6,899/ton. Assuming processing costs of RMB 700/ton, the reference average weekly cost in Zhejiang amounted to RMB 10,701/ton.
Sample Methodology:
DOTP profit is calculated as the difference between the DOTP market price and DOTP production costs. Chempricehub’s reported DOTP profit refers specifically to the theoretical gross margin for DOTP in the Zhejiang region. The statistical period covers weekly average data from last Friday through this Thursday, with data released on working Thursdays between 14:00 and 17:00.
