According to the Commodity Market Analysis System of Shengyi Society, the TDI market in East China in July saw a significant increase in prices due to supply tightening. At the beginning of the month, the average TDI market price was 11733 yuan/ton, and on July 30th, the TDI price was 15333 yuan/ton, an increase of 30.68% during the month and a year-on-year increase of 14.14%.

The TDI market rose strongly in July. Entering July, the payment price for major factories in North China was 15000 yuan/ton, with an increase of 1000 yuan/ton. The supplier has a strong willingness to raise prices and actively promotes price increases. The market supply is tight, and traders are reluctant to sell at low prices, with a focus on fast in and fast out. Subsequently, on July 12th, the force majeure event of Germany’s Covestro TDI affected production capacity by 300000 tons. Due to the surge in export orders and centralized maintenance of domestic facilities, TDI’s global supply was tight and prices skyrocketed. The high-end quotation has risen to around 16500 yuan/ton, and downstream demand has entered the market. Intermediaries are becoming increasingly cautious in entering the market, and the market is fluctuating in the high range at the end of the month.
In July, upstream toluene experienced a weak decline. From July 1st to 30th, the domestic toluene market price dropped from 5820 yuan/ton to 5494 yuan/ton, with a price drop of 5.59% during the period. In July, the fundamentals of the toluene market were weak, with strong supply and weak demand. In addition, crude oil fluctuated weakly, making it difficult for the price market to improve.
In the future analysis, TDI data analysts from Shengyi Society believe that there is a clear resistance from downstream end-users towards high priced TDI, and actual orders are weak. The 360000 tons/year TDI plant of Wanhua Fujian has resumed operation on the 30th, and the end of month settlement price of major factories is about to be released. It is expected that the TDI market will remain stagnant at a high level in the short term, closely monitoring changes in market news.
