Costs Decline as Phthalic Anhydride Prices Fluctuate and Fall This Week

ECHEMI 2025-11-15

November 14, News

This week, the phthalic anhydride market in China fluctuated and declined.

According to the commodity market analysis system, as of November 14, the price of ortho-phthalic anhydride in China was 5893.33 CNY/ton, a decline from 5926.67 CNY/ton on November 7, with a price decrease of 0.56%. The downward trend of phthalic anhydride prices continued, with both phthalic anhydride and ortho-xylene prices showing a downward fluctuation, leading to a reduction in costs. The operating rate of phthalic anhydride enterprises in China slightly increased, ensuring ample supply; the operating load of downstream DOP enterprises also saw a slight increase, maintaining some demand for phthalic anhydride. Due to the decrease in costs and the existing support from demand, the price of phthalic anhydride in China fluctuated downward this week.

Phthalic anhydride production costs in China have decreased.

On November 14, the price of ortho-xylene quoted by Sinopec was 5800 CNY/ton, a decrease of 300 CNY/ton from the price of 6100 CNY/ton on November 1, a price decrease of 4.92%; and a decrease of 100 CNY/ton from the price of 5900 CNY/ton on November 7, a price decrease of 1.69%. The decline in the price of ortho-xylene has led to a reduction in the cost of phthalic anhydride. The operating load of phthalic anhydride equipment has slightly increased, and the supply of phthalic anhydride is sufficient. With the decrease in cost, the pressure for phthalic anhydride prices to fall has increased.

Demand Side: DOP Prices Fluctuate and Decline

According to the commodity market analysis system, as of November 14, the DOP price was 6,883.34 CNY/ton, a fluctuating decrease from the DOP price of 7,025.83 CNY/ton on November 7, with a price decrease of 2.03%. This week, the operating load of China's DOP plasticizer enterprises slightly increased, leading to an increase in DOP production. The demand for phthalic anhydride remains supported, and the downward pressure on phthalic anhydride has weakened.

Future Market Forecast

Phthalic anhydride product data analysts believe that in terms of demand, the operating load of DOP equipment in plasticizer enterprises in China has slightly increased, and the output of plasticizers has risen, providing continued support for phthalic anhydride demand. In terms of costs, the price of ortho-xylene has decreased, leading to a reduction in raw material prices and a decrease in the cost of phthalic anhydride. Looking ahead, with the cost of phthalic anhydride decreasing and demand still supported, the price of phthalic anhydride is expected to fluctuate and fall.
