March 4th News — On March 4th, Kaifeng Jiuhong Chemical Co., Ltd. reported normal operation of its DBP and DIBP production facilities, with a total annual capacity of 240,000 tons. The company quoted DOTP at 8,500 RMB/ton, including tax and ex-factory, representing an increase of 200 RMB/ton. Chempricehub Analysis: **DOTP** – Bull/Bear Score: 1 The DOTP quotation rose by 200 RMB/ton to 8,500 RMB/ton (tax-included, ex-factory), indicating tight market supply and demand, driven by increased demand or limited supply, which directly benefits spot prices. This significant increase reflects improved industry sentiment, likely driven by downstream plastic industry demand. Prices are expected to maintain an upward trend in the short term. **DBP** – Bull/Bear Score: 0.5 Production facilities are operating normally, ensuring stable supply. No direct price movement information is available; however, the price increase of DOTP, a related plasticizer product, may indirectly boost DBP demand or market sentiment. The overall impact is neutral to slightly positive, with attention needed on subsequent actual transaction price changes. **DIBP** – Bull/Bear Score: 0.5 Production facilities are operating normally, ensuring steady supply. The rise in DOTP quotations may have a positive spillover effect on the DIBP market, as both belong to the plasticizer category and share high demand linkage. However, due to the lack of direct price data, the impact is limited, remaining neutral to slightly positive.
