On January 13, the price trend of phthalic anhydride in East China showed a strong consolidation. The mainstream quotation for phthalic anhydride produced via the ortho-xylene method ranged from 6,100 to 6,350 yuan/ton, while the market price for phthalic anhydride produced via the naphthalene method was between 5,700 and 6,050 yuan/ton. The price of industrial naphthalene fluctuated but tended to stabilize, while the price of ortho-xylene experienced a fluctuating increase, leading to a rise in the production cost of phthalic anhydride.

In the downstream market, the plasticizer sector also exhibited a strong consolidation trend. Plasticizer manufacturers reduced their equipment operating rates, while downstream industries maintained rigid demand, purchasing phthalic anhydride primarily based on immediate needs. Despite this, demand support for phthalic anhydride remained intact.

Phthalic anhydride manufacturers slightly lowered their equipment operating rates, but overall supply remained sufficient. Inventory levels of phthalic anhydride were low. It is anticipated that the phthalic anhydride market will continue to show a strong consolidation trend in the near future.
