On April 28, Hualu Hengsheng's BDO unit Line 1, with a capacity of 120,000 tons per year, is operating stably. Line 2, also with a capacity of 120,000 tons per year, underwent maintenance starting April 8 and was restarted on April 25; it is currently ramping up its load. According to Chempricehub's analysis of 1,4-butanediol, the bullish/bearish rating is -1. The article indicates that the stable operation of Line 1 and the restart and gradual load increase of Line 2 at Hualu Hengsheng's BDO unit have boosted the market supply of 1,4-butanediol. The supply-side expansion may exert downward pressure on spot prices, as a lack of synchronized growth in demand could lead to rising inventory pressure and a risk of price correction. Therefore, a generally bearish rating is assigned, reflecting the negative effect of the short-term increase in supply.
