On January 28, Zhenjiang Liancheng Chemical Industry Co., Ltd. quoted the ex-factory price of its 260,000-ton annual production of plasticizer DOP at 7,950 yuan per ton, representing an increase of 100 yuan per ton. PriceSeek's analysis of DOP indicates a bullish-bearish score of 1. The 100 yuan per ton increase in the ex-factory price of DOP by Zhenjiang Liancheng Chemical Industry Co., Ltd. to 7,950 yuan per ton reflects a tight supply in the plasticizer market or increased downstream demand, providing direct positive support for the spot price of DOP. The price increase suggests a strong willingness by the company to maintain higher prices, likely driven by rising raw material costs or improvements in industry supply and demand. It is expected that the spot price of DOP will maintain an upward trend in the short term, which is favorable for market sentiment.
