It is reported that a TDI unit in Northwest China has experienced abnormal fluctuations and requires temporary shutdown, expected to last about a week. PriceSeek analysis on TDI, Bull-Bear Score: 1.5. The article reports that a TDI unit in Northwest China requires temporary shutdown for a week due to abnormal fluctuations, leading to a reduction in TDI supply. The supply disruption is likely to drive up spot prices in the short term, as demand remains stable while inventories may decline. Meanwhile, considering the TDI futures market, near-term contract prices may rise due to supply concerns, reflecting market expectations of a short-term supply gap. This event is a significant positive factor, but since the shutdown is only for a week and not a long-term stoppage, its impact is limited. Therefore, the score is +1.5, falling between a moderate positive and a major positive.
