On September 17, 2026, the gross profit margin for DOP sample production stood at 23 yuan per ton. On that day, the reference price for octanol, a key raw material, was 9,500 yuan per ton, while phthalic anhydride (PA) produced via the ortho method and the naphthalene method were priced at 10,000 yuan per ton and 9,500 yuan per ton, respectively. The weekly average profit was -7 yuan per ton, representing a week-over-week decline of 58 yuan per ton. Although DOP prices rose during the week, raw material costs remained high, causing the DOP market to operate near the cost line throughout the period.
Sample Note: The calculation of DOP profit is defined as the difference between the DOP market price and the DOP production cost, with a processing fee factored in at 300 yuan per ton. Chempricehub’s DOP profit data refers to the theoretical gross margin for DOP in the Shandong region. It is based on daily data collected on Thursdays of working days, with releases scheduled between 14:00 and 16:00 every Thursday.
