SunSirs: Market Trends for Phthalic Anhydride in Some Regions of China on December 17th
December 18 2025 10:32:31SunSirs(John)

On December 17th, the benchmark price of phthalic anhydride according to SunSirs was 5,600.00 RMB/ton, a decrease of 2.89% compared to the beginning of the month (5,766.67 RMB/ton).

On December 17th, the price trend of phthalic anhydride in the East China market remained weak but stable. The mainstream quotation for OX method phthalic anhydride was 5,300-5,500 RMB/ton, while the price of naphthalene-based phthalic anhydride was 5,100-5,300 RMB/ton. Industrial naphthalene prices fluctuated but remained stable, and OX prices also fluctuated but remained stable, resulting in stable phthalic anhydride costs. The downstream plasticizer market was weak but stable, and plasticizer manufacturers maintained stable operating rates. Downstream buyers purchased based on immediate needs, and phthalic anhydride was mainly purchased on demand, leading to weaker demand support. Phthalic anhydride manufacturers maintained stable operating rates, resulting in sufficient supply and low inventory levels. The market is expected to stabilize weakly in the future.

On December 17th, the phthalic anhydride market price in the Jiangsu region remained weak but stable. The mainstream price for OX method phthalic anhydride was 5,300-5,500 RMB/ton, while the mainstream price for naphthalene-based phthalic anhydride was 5,100-5,300 RMB/ton. Phthalic anhydride manufacturers saw a slight increase in equipment utilization, and the overall operating rate remained stable. The domestic phthalic anhydride market had ample supply of spot goods. The price of the raw material OX fluctuated but remained stable, while the price of industrial naphthalene showed weak consolidation. Downward pressure on phthalic anhydride costs persisted. The downstream plasticizer market was weak and declining, leading to reduced operating rates for plasticizer manufacturers and weaker demand for phthalic anhydride. Downstream buyers were only purchasing for immediate needs. The market is expected to stabilize weakly in the future.

On December 17th, the phthalic anhydride market in the Shandong region showed weak and consolidating trends. The mainstream price for OX method phthalic anhydride was negotiated at 5,300-5,500 RMB/ton, while the mainstream price for naphthalene-based phthalic anhydride was 5,100-5,300 RMB/ton. Raw material OX prices fluctuated but remained stable, industrial naphthalene prices showed weak consolidation, and phthalic anhydride production costs remained weakly stable. The downstream plasticizer market experienced a weak decline, while phthalic anhydride manufacturers maintained stable production. The operating rate of phthalic anhydride enterprises remained stable, resulting in ample supply in the market. However, the operating load of plasticizer enterprises decreased, weakening the support for phthalic anhydride demand. The market is expected to stabilize weakly in the future.
