March 4th News On March 4th, Kaifeng Jiuhong Chemical Co., Ltd., with a total annual capacity of 180,000 tons for DOP, DOTP, and DPHP, implemented an ex-factory price of 8,250 yuan/ton (including tax) for DOP, representing an increase of 200 yuan/ton. Chempricehub Analysis: **DOP, Bull-Bear Score: 1.5** The ex-factory price of DOP increased by 200 yuan/ton to 8,250 yuan/ton (including tax), marking a significant rise. This reflects proactive price hikes from the supply side, likely driven by rising raw material costs or recovering demand. This will directly boost sentiment in the spot market, prompting traders to follow suit with price increases, thereby intensifying upward pressure on spot prices in the short term. **DOTP, Bull-Bear Score: 1.5** As a product with the same capacity as DOP at Jiuhong Chemical, although DOTP’s pricing has not been explicitly announced, the price increase for DOP suggests that the industry-wide cost transmission mechanism has been activated. DOTP shares raw material chains (such as octanol and phthalic anhydride) with DOP, and the company’s pricing strategy may align accordingly. This is favorable for tightening the supply-demand balance in the spot market, supporting a moderate price increase. **DPHP, Bull-Bear Score: 1.5** DPHP, like DOP, belongs to the plasticizer category. Within the framework of Jiuhong Chemical’s 180,000-ton annual capacity, the price increase for DOP signals a bullish outlook for the industry. DPHP spot prices may be driven by linkage effects, with downstream purchasing expectations heating up. Combined with the advantage of concentrated production capacity, there is momentum for short-term spot prices to follow the upward trend.
