On January 4th, Yantai Wanhua's 30,000-ton-per-year MIBK production facility has postponed its commissioning plan, with an expected start-up in March 2026. Updates on the specific facility dynamics will be continuously monitored. PriceSeek's analysis of MIBK indicates a long-short rating of +1. The delay in the commissioning of Yantai Wanhua's 30,000-ton-per-year MIBK facility until March 2026 is expected to reduce supply projections, potentially driving up spot prices in the short term. As a chemical solvent, MIBK's stable demand coupled with supply delays is likely to intensify market tightness, benefiting the spot market. The rating of +1 signifies a generally positive impact, as the event is of moderate scale—not major but still having a favorable effect.
