On April 29th, the TDI price was 10700 yuan/ton, a decrease of 11.33% during the month and a year-on-year decrease of 30.97%.

In April, the TDI market in East China was negatively affected by both supply and demand as well as news, causing prices to fall to a low level before rebounding slightly. In early April, the supply of goods was filled quickly and the supply was loose. Affected by the news of tariff policies, the export market is hindered, and downstream market entry is cautious. Domestic demand is relatively flat, with limited demand pull. The market lacks favorable support, and the mainstream price of TDI has fallen to 10000-10500 yuan/ton. In late April, suppliers gathered strength and increased prices, with low-end quotations probing the rise. At the same time, major manufacturers had frequent maintenance plans, but due to demand constraints, the increase was limited.
Supply side: Fujian Wanhua, Xinjiang Juli, Gansu Yinguang operate at medium to high loads. BASF’s 160000 tons/year TDI plant in Shanghai has a maintenance plan in May, while Japan’s Tosa has a maintenance plan from May to July. Other devices maintain stable operation.

In the second half of this month, the upward trend of the domestic ammonium sulfate market has been temporarily suspended. The operating rate of coking enterprises remains stable, and the operating rate of their internal equipment is at a low level. After the continuous rise in ammonium sulfate prices, downstream restocking enthusiasm weakened, and there was resistance to high prices. The ammonium sulfate market began to consolidate and operate. As of April 28th, the mainstream ex factory quotation for coking grade ammonium sulfate in Shandong region is around 1010 yuan/ton. Domestic grade ammonium sulfate, the mainstream ex factory quotation in Shandong region is around 1060-1090 yuan/ton.

This week, the overall performance of the xylene market is weak, with market prices falling overall and slight differences in various markets.

Market forecast: The market expects that there is still upward potential for crude oil in the future, and the cost support is still acceptable. Recently, the inventory in Shandong region has been low on the supply side, and refineries are actively shipping. The overall supply of goods from ports in East and South China is still acceptable, and the overall supply side is relatively stable. The overall downstream procurement on the demand side tends to be rigid, and the support on the demand side is limited. It is expected to experience narrow fluctuations in the short term.

Raw material side: The market price of raw material propylene has shown a downward trend, which provides weak support for the cost of epoxy propane. According to the market analysis system of Shengyi Society, as of April 25th, the benchmark price of propylene in Shengyi Society was 6710.75 yuan/ton, a decrease of -0.52% compared to the beginning of this month (6745.75 yuan/ton).
On the demand side, the downstream polyether market’s capacity utilization rate has decreased, inventory has accumulated, and most enterprises have experienced a negative load reduction phenomenon. Pre May Day, stocking up on demand is the main focus, and the trading atmosphere is cold. The downstream terminal market is affected by tariff policies, resulting in a significant decrease in export orders and limited procurement of raw materials. Overall, the demand is facing insufficient support from the epoxy propane market, and it is expected that the price of epoxy propane will continue to decline in the later stage.
Market forecast:
An epoxy propane analyst from Shengyi Society believes that the downstream demand side of epoxy propane is weak, and pre holiday stocking is mainly based on demand. The market trading atmosphere is cold, and the demand support is insufficient. It is expected that the epoxy propane market will continue to bottom out in the later stage, and more attention should be paid to changes in raw material prices and downstream supply and demand.
