2、 Market analysis
This week, the price of bromine has remained stable, with a reference price of 24000 to 26000 yuan/ton for spot bromine production in Shandong region. The temperature has risen this week, and domestic bromine enterprises have started working steadily. Most manufacturers focus on stabilizing prices, while downstream enterprises prioritize urgent needs. In terms of raw materials, domestic sulfur prices have been running weakly, with an average market price of 2501 yuan/ton at the beginning of the week and 2474.33 yuan/ton over the weekend. The price has decreased by 1.07% and increased by 129.81% compared to the same period last year. Downstream demand is generally average.
Prediction: Bromine prices are expected to remain strong in the near future, while upstream sulfur prices are expected to remain stable. Bromine prices are expected to remain strong this week, while downstream purchases will be made as needed. Bromine enterprises focus on stabilizing prices. It is expected that bromine will continue to consolidate and operate in the later period, depending on downstream market demand.

This week, the domestic fluorite price trend has slightly declined. As of the weekend, the average domestic fluorite price was 3606.25 yuan/ton, a decrease of 1.37% from the early week price of 3656.25 yuan/ton and a year-on-year decrease of 4.63%.

Supply side: Some manufacturers have started production, and the supply of fluorite has increased
The current situation of the game in the domestic fluorite industry still exists. Overall, the operating rate of enterprises has not changed much. Upstream mining is tight, backward mines will continue to be eliminated, and new mines will be added. Mineral investigation work is still difficult. In addition, national departments need to rectify fluorite mines, and fluorite mining enterprises are facing increasingly strict safety and environmental protection requirements. The difficulty of operating fluorite mines has increased, and the shortage of raw materials has limited the operation of fluorite enterprises. The supply of fluorite sources is still tight. However, as the temperature rises, northern enterprises are gradually starting production, and the supply of fluorite from on-site enterprises has increased. This week, the fluorite market has slightly declined.
Demand side: The price of hydrofluoric acid is temporarily stable, and the refrigerant market is still acceptable
This week, the domestic price of hydrofluoric acid has remained stable, with mainstream prices ranging from 11200-11700 yuan/ton in various regions of China. Some downstream hydrofluoric acid units are still shut down, and there is little change in the spot supply of hydrofluoric acid. Manufacturers mainly purchase hydrofluoric acid on demand, and the overall production of hydrofluoric acid remains at more than 50%. Fluorine enterprises maintain essential orders, and hydrofluoric acid enterprises are in a loss making state. They are not actively purchasing raw fluorite. Recently, some hydrofluoric acid manufacturers have shown a downward trend, which has slightly affected the price of fluorite.
The downstream refrigerant market in the terminal industry is still promising, and the terminal policy of the refrigerant industry is being strengthened. Demand is expected to achieve substantial improvement. Fluorine chemical enterprises within quota control have strong confidence in raising prices in the refrigerant market. Currently, the pace of high price procurement is relatively slow, but the industry inventory is transmitting in a positive and orderly manner. Due to high prices, the enthusiasm for stocking up in the terminal industry is low, and upstream products are mainly purchased on demand. The trend of refrigerant market is average, while the fluorite market has slightly declined.
In addition to the traditional demand in the refrigerant industry, fluorite, as an important mineral raw material for modern industry, is constantly developing in emerging fields. It is also applied in strategic emerging industries such as new energy and new materials, as well as in national defense, nuclear industry and other fields, including lithium hexafluorophosphate, PVDF、 Graphite negative electrodes, photovoltaic panels, etc., have received certain support in the application of fluorite due to the demand for new energy and semiconductors.
Market forecast: In the near future, it is difficult to improve the supply of domestic fluorite mines, and some mines have stopped production and undergone safety inspections. The tight supply of fluorite mines is a positive support for the fluorite market. However, in some areas, the lack of active fluorite procurement has led to an increase in inventory. In addition, downstream resistance to high prices is severe, and hydrofluoric acid enterprises mainly purchase on demand, with no actual increase in demand. Overall, the fluorite market price has slightly decreased in the short term.

(Note: Cycle refers to January 1, 2012 to present)
Market forecast: According to the commodity analysis system of Shengyi Society, the current trend of soda ash prices is rising. The maintenance of some soda ash plants in May will have a positive impact on the market. At the same time, the downstream market is strong and the atmosphere for soda ash transactions is good. It is expected that soda ash prices will be strong and upward in the later stage. In the long run, downstream demand support is limited, and soda ash prices will first rise and then stabilize, depending on downstream market demand.

According to the Commodity Market Analysis System of Shengyi Society, after a wide decline in the TDI market in East China in April, it rebounded slightly and the overall trend declined. At the beginning of the month, the average TDI market price was 12066 yuan/ton. 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.

From April 1st to 27th, the domestic toluene market price fell from 6120 yuan/ton to 5490 yuan/ton, with a price drop of 10.29% during the period. Crude oil prices fell sharply this month, and the market sentiment was weak. Downstream purchases were made on dips. The overall performance of the aromatic hydrocarbon market is weak, and the toluene market is dragged down by weak prices.
In the future analysis, TDI data analysts from Shengyi Society believe that the current TDI market demand is average, and although suppliers are actively promoting it, the upward trend is weak. Pay close attention to the changes in market supply and demand in May, and expect the TDI market to consolidate and operate within a certain range in the short term.

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.
