The hurricane in the United States led to the temporary shutdown of foreign MDI devices, and the relative shortage of supply gave birth to the bullish mood of traders. However, the downstream slightly resisted the high price, the traders’ shipment was not smooth, and the market entered a high consolidation period.

Wanhua’s quotation in the second stage increased month on month, the weekly guidance price of Shanghai kostron increased, and the temporary shutdown of foreign MDI devices caused by the hurricane in the United States continued to give rise to the bullish sentiment of traders.

In the last ten days of the month, some suppliers’ factories stored maintenance plans in the later stage, and the supply of goods became tight; The maintenance of devices in Europe and the Middle East is concentrated from September to October, the foreign supply is tightening, and most customers in downstream industries have low inventory. Under the premise of tight supply, the negotiated transaction price is gradually pushed up, and the increase is obvious near the end of the month.

In September, the main driving force of the price rise in the aggregate MDI market was the gradual tightening of supply; Later, as it gradually entered the end of the month, Huntsman’s listing price increased widely in October, stimulating the mentality of the industry. However, Wanhua’s listing price in October was more lower than that of Shanghai factories, the mentality of suppliers was different, and the mentality of the industry was tangled. MDI analysts of business society expect that the domestic MDI market is dominated by high-level consolidation.
