According to the Commodity Market Analysis System of Shengyi Society, the price of polyester bottle flakes (PET) has increased this week. As of April 27th, the average selling price of PET (polyester bottle flakes) is 5787 yuan/ton.

From the perspective of price fluctuations, at the beginning of the week, international oil prices began to rise, which put upward pressure on the cost side of the PET market. At the same time, there is a tightening situation in the local spot circulation links, and the atmosphere of tight market supply is gradually becoming stronger. In addition, news of mainstream factories jointly reducing production has emerged in the market, and multiple factors have combined to drive up PET market prices. Low price sources in the market have been quickly digested and are difficult to find. Crude oil experienced a pullback at one point, and the news of production cuts was not actually implemented. There was a strong wait-and-see sentiment in the market, which limited further growth in the PET market and led to a partial decline in gains. As the weekend approaches, crude oil and raw material prices have rebounded again, injecting new upward momentum into the PET market. At the same time, due to the consideration of ensuring the stability of processing fees, the factory has a strong willingness to guarantee processing fees. Under the dual effects of cost support and the factory’s willingness to raise prices, the PET market quotation continues to rise.
On the supply side, the operational load of industry equipment has increased. The 300000 ton bottle tablet plant of Chongqing Wankai resumed operation in late April, and the newly put into operation 750000 ton production capacity in Sanfangxiang was also restarted and put into production in the early stage. With the restart and operation of these devices, there are still incremental expectations on the supply side, and the future market supply of goods may further increase.
The demand side presents a complex situation. Currently, the soft drink industry is in the off-season of seasonal consumption, and market demand is relatively flat. However, it is worth noting that as temperatures gradually rise, the peak season for soft drink consumption is approaching, and demand expectations are improving. In addition, the export market has performed well with a high year-on-year growth rate, providing certain support for the demand of the PET market.
In addition, at the policy level, Zhengzhou Commodity Exchange will adjust the trading margin standard for bottle futures contracts to 9% and the limit up and limit down range to 8% from the settlement date of April 29, 2025. This may have a certain impact on market trading activity and price fluctuations.
In response to the current market situation, Shengyi Society believes that the PET market for polyester bottle chips will still have support in the short term, but downstream follow-up is not as expected, and the PET market may experience a narrow adjustment. The actual trend still needs to pay attention to the follow-up equipment, demand situation, and cost support under the traction of crude oil.

The domestic fluorite price trend has slightly declined this week. As of the weekend, the average domestic fluorite price was 3712.5 yuan/ton, a decrease of 0.34% from the early week price of 3725 yuan/ton and a year-on-year increase of 1.89%.

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, and the mainstream price for hydrofluoric acid negotiations in various regions of China is 11700-12200 yuan/ton. 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 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 purchasing at high prices 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 April is low, and upstream products are mainly purchased on demand. The refrigerant market trend is temporarily stable, while the fluorite market trend 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 is prone to decline but difficult to rise in the short term.

According to the Commodity Market Analysis System of Shengyi Society, as of April 21, the average price of 85% industrial grade formic acid in China was 3400 yuan/ton, which remained unchanged compared to the beginning of the month and increased by 3.03% compared to the same period last year at 3300 yuan/ton.

There is no significant change in the overall trading of 85% industrial grade formic acid in China, and the cargo holders will ship according to the market conditions. From a cost perspective, the average price of raw material methanol in East China ports fell from 2459 yuan/ton to 2415 yuan/ton last week (April 14-18), a month on month decrease of 8.98% and a year-on-year decrease of 10.25%. The supply of methanol in the coastal market is increasing, but market confidence is insufficient, and the overall port market is still showing a weak trend. Due to the shutdown of some facilities and tight supply in some regions of the mainland methanol market, coupled with low inventory levels of enterprises, traders have a positive attitude towards purchasing goods. Production enterprises have raised prices to ship, and the overall methanol market in mainland China is operating strongly, with strong cost support from the formic acid market. From the demand side, downstream rubber, pharmaceutical, and pesticide industries are mainly engaged in essential procurement, with a relatively balanced supply and demand and a stable market focus.
The formic acid data analyst from Shengyi Society believes that there is currently cost support and downstream demand replenishment. It is expected that in the short term, the domestic industrial grade formic acid market will remain stable at 85%, and more attention needs to be paid to market news guidance.

This week, the epoxy propane market trend is weak and stable. According to the monitoring and analysis system of Shengyi Society, as of April 18th, the benchmark price of Shengyi Society’s epoxy propane was 7450 yuan/ton, a decrease of -6.73% compared to early April.

Price influencing factors:
Supply side: Currently, there is ample supply of spot goods in the market, and some devices have maintenance plans in place.
Raw material side: The market price of raw material propylene has slightly increased, and the fluctuation has little impact on the market. According to the market analysis system of Shengyi Society, as of April 17th, the benchmark price of propylene in Shengyi Society was 6723.25 yuan/ton, a decrease of -0.33% compared to the beginning of this month (6745.75 yuan/ton).
Downstream demand side: The downstream market is mostly wait-and-see, with insufficient support from the demand side. The trading atmosphere is average, with a focus on on-demand procurement.
Market forecast:
Business Society’s epoxy propane analyst believes that the supply of epoxy propane is loose, the downstream trading atmosphere is average, and on-demand procurement is the main focus, with insufficient support from the demand side. It is expected that the epoxy propane market will continue its weak and stable trend in the later stage, and more attention should be paid to changes in raw material prices and downstream supply and demand.

According to the Commodity Market Analysis System of Shengyi Society, from April 7th to April 14th, the domestic butadiene market price decreased from 10700 yuan/ton to 8966.67 yuan/ton, with a price reduction of 16.2% during the period. The domestic butadiene market has experienced a significant decline in this cycle, and under the influence of international news such as equivalent tariffs, the crude oil and synthetic rubber futures markets have experienced a wide decline. The cost and demand sides have had a significant impact on the butadiene market, dragging down the mentality of the spot market. On the supply side, the port arrival situation this week is good, and the overall supply of butadiene is relatively loose. Under the comprehensive influence of the above news, the butadiene market fell sharply this week. Due to a slight improvement in fundamentals over the weekend, the butadiene market has slightly rebounded.

Cost wise: The international oil price market has experienced a significant decline. As of April 11th, the settlement price of the main contract for WTI crude oil futures in the United States was $61.50 per barrel, and the settlement price of the main contract for Brent crude oil futures was $64.76 per barrel. On the one hand, the US tariff trade war and tariff trade barriers have had a huge impact on the global economy, increasing uncertainty in the future. The market believes that the risk of the United States falling into an economic recession has increased, and this will have a huge negative impact on global economic growth. On the other hand, the Organization of the Petroleum Exporting Countries and its allies (OPEC+) announced future production increases, which also had a negative impact on crude oil and led to a significant decrease in international oil prices.
Supply side: The listed price of butadiene for various sales companies of Sinopec is 10000 yuan/ton, and it will be lowered by 1200 yuan/ton this week.
Demand side: According to the Commodity Market Analysis System of Shengyi Society, as of April 11th, the market price of butadiene rubber in East China was 12290 yuan/ton. The price of raw material butadiene has significantly decreased, and the cost support for butadiene rubber has weakened significantly; The production of butadiene rubber has slightly decreased, and there is not much pressure on the supply side; Downstream production slightly decreased, and inquiries for Shunding rubber were light due to the impact of international trade trends. Merchant offers have significantly decreased, with mainstream quotes in Qilu, Daqing, Sichuan, and Yangtze Shunding in East China ranging from 12100 to 12500 yuan/ton as of April 11th.
Market forecast: The crude oil market is expected to experience a wide decline this cycle, with many negative factors on the cost side. In terms of supply, the recent arrival situation at the port is good, and the supply of butadiene is good, but the supply side is relatively short. The downstream synthetic rubber futures market on the demand side has experienced a wide decline, and the overall operating rate has decreased. The overall demand still maintains on-demand procurement. Overall, the supply and demand performance of the butadiene market is bearish, and it is expected to be mainly stable, moderate, and weak in the short term.

According to the Commodity Market Analysis System of Shengyi Society, the domestic natural rubber spot market has experienced a significant decline in recent days (4.1-4.10). As of April 10th, the spot rubber market in China was around 14598 yuan/ton, a decrease of 9.73% from 16172 yuan/ton on the first day. Currently, influenced by international trade news, the atmosphere in the domestic rubber market is relatively weak. The high prices of raw materials have fallen back; Domestic Tianjiao Port inventory continues to increase; Downstream production has slightly decreased; The significant decline in the Shanghai rubber market has led to a significant adjustment in the natural rubber spot market.

In the second quarter, the overseas main production areas are expected to gradually increase production volume, coupled with the current good weather and high price stimulation, rubber farmers are cutting rubber smoothly, and rubber prices are difficult to stabilize at high levels; At the same time, Yunnan Province in China has conducted trial cutting, and it is expected that the supply of rubber raw materials at home and abroad will increase, leading to a decrease in the price of natural rubber raw materials. As of April 10th, the price of Thai glue was 57.50 baht/kg, a significant decrease from the pre holiday price of 68.00 baht/kg.
Natural rubber inventory continues to increase slightly, but overall it remains at a high level. As of April 6, 2025, the total inventory of Tianjiao bonded and general trade in Qingdao area was 620700 tons, an increase of 0.08 million tons or 0.13% compared to the previous period.
Supply and demand side: Downstream tire production has slightly decreased, coupled with the impact of international trade trends, there is a strong wait-and-see atmosphere in the natural rubber market, and inquiries are light. As of April 6th, the operating load of semi steel tires in domestic tire enterprises was around 7.8%; The construction of all steel tires by tire enterprises in Shandong region has slightly increased to around 6.6% of the load.
Market forecast: When domestic and international raw material prices fall from high levels, coupled with unclear international trade trends and weak downstream inquiries, the support for natural rubber will weaken, but the inventory of Tianjiao Port will continue to grow; Overall, it is expected that the natural rubber market will consolidate weakly in the later stage.

1、 Price trend

According to the Commodity Market Analysis System of Shengyi Society, as of April 7th, the reference average price of the domestic urea market was 1985 yuan/ton, a decrease of 0.50% from the reference average price of 1995 yuan/ton on April 1st.
2、 Market analysis
market conditions
This week, the domestic urea market has been weak and declining. As of April 7th, the factory price of urea in Shandong region is around 1900-1930 yuan/ton, in Hebei region it is around 1900 yuan/ton, in Henan region it is around 1910 yuan/ton, in Hubei region it is around 1910 yuan/ton, and in Liaoning region it is around 1940 yuan/ton.
Supply and demand situation
In terms of supply, the urea market has sufficient supply this week, and inventory pressure is still present, with stable shipments from enterprises. In terms of demand, the volume of new orders decreased this week, downstream demand slowed down, and a cautious attitude increased. Business owners mainly placed early orders.
3、 Future forecast
Business Society’s urea analyst believes that the recent downward trend in the domestic urea market is the main reason. At present, the demand in the industrial and agricultural markets is weakening, and market transactions are slowing down. It is expected that the domestic urea market price will weaken and decline in the short term.

At the beginning of April, the supply of epichlorohydrin in the market was reduced, and prices were tentatively pushed up. According to the monitoring and analysis system of Shengyi Society, as of April 1st, the benchmark price of Shengyi Society’s epichlorohydrin was 8900 yuan/ton, an increase of 0.56% compared to the end of March (8850 yuan/ton).
Price influencing factors:

Raw material side: The market price of raw material propylene glycerol is mainly consolidating, with little impact on epichlorohydrin. According to the market analysis system of Shengyi Society, as of March 31st, the benchmark price of propylene in Shengyi Society was 6735.75 yuan/ton, a decrease of -1.14% compared to the beginning of this month (6813.25 yuan/ton).
Supply side: The expected supply of epichlorohydrin in the April market is expected to decrease. Expected production may decrease to below 100000 tons.
Downstream demand side: The downstream epoxy resin market supply remains normal, with a capacity utilization rate of over 50%. But the terminal demand is weak, trading is not smooth, and the main focus is on purchasing for essential needs. At present, the mainstream price of liquid epoxy resin in East China is around 13050-13850 yuan/ton.
Market forecast: Analysts from Shengyi Society believe that although some production enterprises’ equipment shutdowns and maintenance have led to a reduction in supply, downstream market demand is weak, traders’ purchasing mentality is not positive, and market trading is not smooth. It is predicted that the epoxy chloropropane market may experience a narrow upward trend in the later stage, and more attention still needs to be paid to changes in market supply and demand.

1、 Price trend
According to monitoring data from Business Society, the price of caustic soda first rose and then fell in March. At the beginning of the month, the average price of caustic soda in Shandong region was 936 yuan/ton. At the end of the month, the price of caustic soda in Shandong region was 907 yuan/yuan, a decrease of 3.1% and an increase of 6.46% compared to the same period last year. On March 30th, the Business Social Chemical Index was 827 points, unchanged from yesterday, a decrease of 40.93% from the highest point of 1400 points during the cycle (October 23, 2021), and an increase of 38.29% from the lowest point of 598 points on April 8, 2020. (Note: The cycle refers to the period from December 1, 2011 to present)

2、 Market analysis
According to survey data from Shengyi Society, the price of caustic soda first fell and then rose. The price of caustic soda in Jiangsu region is currently stable, with a mainstream market price of around 980-1050 yuan/ton for 32% ion exchange membrane alkali. The price of caustic soda in Shandong region is running weakly, with a mainstream market price of around 870-940 yuan/ton for 32% ion exchange membrane alkali. The overall upward trend in caustic soda prices in early March was mainly due to manufacturers stopping for maintenance, which eased the pressure on caustic soda inventory. Downstream alumina prices remained at 3200-3450 yuan/ton, indicating a decent demand for caustic soda. In late March, the overall price of caustic soda fell, and the main caustic soda inventory accumulated. With the main regional liquid caustic soda procurement prices further lowered. The main regional liquid alkali market has experienced a decline, and non aluminum demand is high, so it is necessary to wait and see. The market demand is average.
Business analysts believe that in the near future, the price of caustic soda has been weak in the operating market, with accumulated inventory in some areas and average downstream demand. While supply continues to increase, demand has not shown significant improvement. Overall, it is expected that caustic soda will maintain a weak operating market in the later period, depending on downstream market demand.

In March, the epoxy propane market showed a situation of mixed ups and downs. At the beginning of March, the epoxy propane market showed a stable and declining trend. Due to the restart of some factory facilities and sufficient market supply, coupled with rising raw material prices and insufficient downstream demand, corporate profits have narrowed, leading to a decline in prices. Since mid March, due to the reduction in supply of raw material liquid chlorine in the market, prices have risen significantly, which has provided some support for the price of epoxy propane and led to an upward trend. At the end of March, the epoxy propane market experienced a slight decline in price due to weak downstream demand and insufficient terminal digestion. According to the Commodity Market Analysis System of Shengyi Society, as of March 28th, the benchmark price of Shengyi Society’s epoxy propane was 7987.5 yuan/ton, a decrease of -0.47% from the beginning of the month.

Price influencing factors:
Supply side: Currently, market inventory has decreased. Enterprises tend to have a strong mentality of supporting prices.
Raw material side: In March, the raw material propylene and liquid chlorine markets showed mixed fluctuations. At the beginning of the month, there was a small peak in propylene prices, which provided strong support for the epoxy propane market. In mid March, the price of propylene remained within the range of fluctuations, which had limited impact on the trend of the epoxy propane market. However, due to supply reduction, the price of raw material liquid chlorine increased significantly, which provided some support for the price of epoxy propane. Overall, the epoxy propane market showed an upward trend. At the end of the month, there was a significant drop in propylene prices, and the cost support for epoxy propane was insufficient, resulting in a strong market price. According to the market analysis system of Shengyi Society, as of March 27th, the benchmark price of propylene in Shengyi Society was 6798.25 yuan/ton, a decrease of -0.22% compared to the beginning of this month (6813.25 yuan/ton).
Downstream demand side: In March, the overall demand for epoxy propane in the downstream market was weak, with insufficient terminal digestion. Traders had a cold purchasing mentality and focused on on-demand procurement, resulting in a decrease in market order volume and poor market transmission. In addition, the operating rate of some downstream products has also shown a downward trend. Overall, the downstream downturn has had a certain impact on the trend of the epoxy propane market.
Market forecast:
An epoxy propane analyst from Shengyi Society believes that the current supply side shipments of epoxy propane market are normal and there is still some support. However, the downstream trading atmosphere is generally average, with on-demand procurement as the main focus and insufficient demand side support. Many enterprises are mainly pushing prices. It is expected that the epoxy propane market will continue to fluctuate within a certain range in the later stage, and more attention should be paid to changes in raw material prices.
