On November 5, 2026, the gross profit for DOP sample production stood at CNY 33 per ton. The primary raw material prices on that day were as follows: n-octanol at CNY 10,000 per ton, phthalic anhydride (PA) produced via the ortho-xylene method at CNY 10,400 per ton, and PA produced via the naphthalene method at CNY 10,000 per ton. The weekly average profit was CNY 7 per ton, representing a week-on-week decline of CNY 36 per ton. During the week, prices for both raw materials (n-octanol and PA) and DOP trended downward from high levels; however, since DOP prices fell ahead of its raw materials, market profit margins contracted.
