PriceSeek Analysis on 1,4-Butanediol (BDO), Bull-Bear Score: -1.5
The imposition of high provisional anti-dumping duties ranging from 105.6% to 113.7% by the EU will restrict China's BDO exports to the European market starting from February 6, 2026. This is expected to result in oversupply in the domestic Chinese market and downward pressure on spot prices. The score of -1.5 reflects the extremely high tariff rates and their immediate effect. Although production will not be completely halted, it is anticipated that domestic inventory accumulation in the short term will lead to significant price reduction pressure, classifying this as a generally significant bearish event.
