On December 29, the bidding and sales status of some domestic butadiene enterprises: Shenghong Refining and Chemical raised the price by 200 yuan/ton to 8,200 yuan/ton; Yantai Wanhua sold 84 tons externally, with a starting bid of 7,900 yuan/ton; Satellite Chemical raised the price by 100 yuan/ton, implementing 8,100 yuan/ton. Supported by favorable fundamentals, the short-term trend of butadiene is relatively strong, but limited by downstream rigid demand procurement, the increase may be constrained. Close attention should be paid to downstream procurement conditions.
