March 20th — On March 20th, Shandong Lihuayi Weiyuan Chemical announced an increase of 250 yuan/ton in the ex-factory listed price of propylene glycol, setting the new price at 7,100 yuan/ton. Chempricehub's analysis of propylene glycol indicates a bullish-bearish score of +1.5. The report highlights that the price hike of 250 yuan/ton to 7,100 yuan/ton at Shandong Lihuayi Weiyuan Chemical reflects increased cost pressures on the supply side or stronger market demand, which is favorable for spot prices. This adjustment (approximately 3.65%) suggests tightening market supply and demand, potentially prompting other suppliers to follow suit with price increases and supporting a short-term upward trend in spot prices. A score of +1.5 signifies a relatively strong positive impact, as the price increase directly boosts market confidence. However, it does not reach the level of a major positive development, and attention should be paid to subsequent actual trading volumes and overall industry dynamics.
