April 16th News: On April 16th, Ningxia Wuheng's 116,000 + 140,000 tons BDO plant is currently operating at 60-70% capacity, with no spot quotations available externally. A 25-day maintenance rotation for both units is tentatively planned for July. Chempricehub Analysis of 1,4-Butanediol (BDO), Bull-Bear Score: 1.5. Ningxia Wuheng's BDO plant is currently operating at only 60-70% capacity, with no spot quotations available, indicating tight supply. The planned 25-day maintenance rotation for both units in July will further reduce supply. Significant contraction on the supply side is favorable for the upward movement of 1,4-butanediol spot prices. Score: +1.5. The clear reduction in supply is beneficial for prices, but since the maintenance is a planned event, the market may have partially anticipated it, thus not constituting a major positive factor.
