Based on the Jiangsu region, today Jiangsu o-xylene-route PA closed at CNY 10,100/mt, up CNY 250/mt from the previous trading day, in line with the morning expected price. Today, the domestic phthalic anhydride market price center moved higher. Driven by rising feedstock o-xylene prices, the phthalic anhydride market price center rose on cost-side support.

3. Production Dynamics

Today, domestic phthalic anhydride capacity utilization fell to 57%, with units remaining stable. On the profit side, feedstock o-xylene prices rose, and o-xylene-route PA market prices in East China increased. The theoretical profit for the o-xylene-route PA industry was CNY 346/mt. In Hebei, naphthalene-route PA prices rose, while feedstock industrial naphthalene tender prices were temporarily stable. The theoretical profit for the naphthalene-route PA industry was CNY 85/mt.

4. Price Forecast

Currently, cost-side factors remain the main driver of the market. Strong cost support from upstream feedstock, together with low inventory in the domestic phthalic anhydride industry, provides some support to the market. However, weak end-use demand may constrain follow-up transactions at the high end of the market. In the short term, domestic phthalic anhydride market prices are expected to enter high-level consolidation.

5. Related Products

o-Xylene market: In East China, o-xylene market prices rose, with reference at around CNY 9,850/mt for self-pickup. Supported by strong cost-side support from the upstream aromatics chain, major petrochemical plants raised prices, driving the market price center higher.

DOP market: Today, domestic octanol market prices continued to rise. As octanol prices have risen too much within the week, they are now at a high level for the year. Downstream users' purchasing enthusiasm was moderate, and a wait-and-see atmosphere was strong in the market. Traders with profitable positions offered slightly lower prices; spot inventories in the market were relatively low, and the overall price center operated at a high level.

    The o-xylene feedstock cost push is lifting PA prices, but with capacity utilization at 57% and downstream DOP demand tepid, I see margin upside capped near term despite firm cost support.
