The domestic TDI market is characterized by incremental trading volume and terminal replenishment. Traders compete for market share and take the opportunity to clean up inventory and consume surplus. In May, there was an enormous drop, and the middlemen lacked the opportunity to deliver goods. At the end of the month, they just needed more inquiries, which made it difficult to form a strong support for the industry at present. At present, the market price of domestic goods is more than 12800 yuan/ton, and the supply of goods in Shanghai is 13200 yuan/ton. Business associations expect the TDI market to be weak and stable, and pay attention to the factory information guide.
