On January 7, Gaoqiao Petrochemical raised its acetone offer by 100 yuan to 4,300 yuan/ton, ex-works with cash payment. The company's 240,000-ton/year phenol-acetone unit in Caojing is currently shut down, and further updates will be provided as the situation develops. PriceSeek Analysis: Acetone – Bull-Bear Score: 2 Gaoqiao Petrochemical's acetone offer has increased by 100 yuan/ton to 4,300 yuan/ton, and the shutdown of its 240,000-ton/year phenol-acetone unit has reduced supply, providing significant support to spot prices. Short-term prices are expected to rise notably. MIBK – Bull-Bear Score: 1 As a downstream product of acetone, the tight supply and rising prices of acetone may increase MIBK production costs, supporting its spot prices. This constitutes a moderate positive factor, though the extent of the impact depends on downstream demand transmission.
