Based on the Jiangsu region as a benchmark, today's closing price for OX-process PA in Jiangsu was 10,400 CNY/ton, a decrease of 100 CNY/ton from the previous trading day, consistent with morning price expectations. Domestic phthalic anhydride prices declined today. Affected by the drop in feedstock ortho-xylene prices, cost support weakened, putting pressure on the market.

  1. Production Dynamics

Today, the domestic capacity utilization rate for phthalic anhydride remained stable at 57%, with overall plant operating rates steady. Regarding profitability, the decline in feedstock ortho-xylene prices led to a drop in East China OX-process PA market prices, resulting in a theoretical industry profit of 692 CNY/ton for the OX process. In Hebei, naphthalene-process PA prices fell while industrial naphthalene feedstock prices remained stable, yielding a theoretical industry profit of 735 CNY/ton for the naphthalene process.

  1. Price Forecast

Currently, cost support from the upstream aromatics industry chain is weakening. Additionally, expectations of increased capacity utilization in the naphthalene-process PA sector have exacerbated market wait-and-see sentiment. Short-term domestic phthalic anhydride prices are expected to continue trending downward.

Ortho-Xylene Market: Ortho-xylene prices in East China declined, referencing around 9,800 CNY/ton for ex-warehouse delivery. Cost support from the upstream aromatics industry chain weakened, leading to bearish market sentiment and downward pressure on prices.

DOP Market: Today, feedstock octanol prices dropped, causing DOP prices to follow suit with further declines. However, as it is early in the week, market participants adopted a cautious wait-and-see approach. Overall inquiry activity was weak, with end-users primarily maintaining small-volume purchases based on rigid demand.

    With OX feedstock costs dropping, PA prices softened while capacity utilization held steady at 57%. Although margins remain positive for both processes, the decline in downstream DOP signals cautious demand. I expect con..
