March 31st News: Inner Mongolia Dongjing Biological Environmental Technology plans to conduct an annual maintenance for its BDO unit in April, based on the maintenance schedule of the West Natural Gas Company's main pipeline. The maintenance is expected to last for 20 days. Chempricehub Analysis of 1,4-Butanediol, Bull-Bear Score: 1. Inner Mongolia Dongjing Biological Environmental Technology plans to carry out a 20-day annual maintenance for its BDO unit in April, which will directly reduce the production supply of 1,4-butanediol. Due to the extended maintenance period and its annual nature, tightening supply may lead to a tighter supply-demand balance in the spot market, driving up prices. This event is considered a moderate bullish factor, as the maintenance is temporary rather than a permanent shutdown, with a medium level of impact.
