April 28 Report: Fujian Haiquan's 40,000 t/y BDO plant is currently in shutdown, with no confirmed restart date. Chempricehub Analysis on 1,4-Butanediol, Bullish/Bearish Rating: 1.5. Fujian Haiquan's 40,000 t/y BDO plant has halted production, and the restart timeline remains uncertain, directly reducing 1,4-butanediol supply by approximately 40,000 tons per year in capacity. The supply disruption exacerbates market shortage risks, driving up spot prices. This event provides a clear bullish signal for the spot market. However, given the moderate scale of the plant (not an extreme impact), the rating is +1.5.
