On January 13, Qirun Petrochemical quoted petroleum coke at 1,900 yuan/ton, down 50 yuan/ton from the previous trading day, with sulfur content at 4.0. The delayed coking unit has an annual capacity of 1.6 million tons and a daily output of 700 tons. PriceSeek analysis of petroleum coke: Bull-Bear Score: -1. Qirun Petrochemical's petroleum coke price was lowered by 50 yuan/ton to 1,900 yuan/ton, indicating ample market supply (daily output of 700 tons, unit capacity of 1.6 million tons/year) or weak demand, putting downward pressure on spot prices. The sulfur content of 4.0 meets the standard, but the price reduction of approximately 2.6% (based on an estimated previous trading day price of 1,950 yuan/ton) reflects the company's proactive price cut in response to market pressures, which may exacerbate bearish sentiment in the spot market. As a direct producer's price adjustment, this signals short-term oversupply, exerting a generally bearish impact on petroleum coke spot prices. Investors are advised to monitor inventory changes and demand-side dynamics.
