Weekly Statistical Data on Production Profit of DOP Samples in China (September 18–24, 2026)

On September 24, 2026, the gross production margin for DOP samples stood at RMB 93 per ton. The reference prices for key raw materials on that day were RMB 8,900 per ton for octanol, RMB 9,700 per ton for phthalic anhydride (PA) produced via the ortho-xylene process, and RMB 8,500 per ton for PA produced via the naphthalene process.

The weekly average profit was RMB 31 per ton, representing a week-on-week increase of RMB 31 per ton. During the week, DOP prices rebounded from their lows while raw material prices declined. Despite this, the DOP market remained near its cost line, and products made using ortho-xylene-based PA continued to operate in a loss-making range.
