Chempricehub, November 9

On November 9, the phthalic anhydride (PA) market in Shandong showed a downward trend. The mainstream quoted prices for ortho-xylene-based PA were RMB 10,300–10,400 per tonne, while naphthalene-based PA was quoted at RMB 9,700–9,800 per tonne. Crude oil prices fluctuated lower, weakening cost support. Raw material prices declined: ortho-xylene fell, and industrial naphthalene remained weakly consolidated, leading to reduced production costs for PA. Downstream plasticizer markets also experienced volatile declines. Operating rates of PA producers stabilized, maintaining steady supply. However, operating rates of plasticizer enterprises decreased slightly, reducing essential demand support for PA and driving its market price down.
