According to the Commodity Market Analysis System of Shengyi Society, from April 7th to 11th (as of 15:00), the average price of methanol in East China ports in the domestic market fell from 2487 yuan/ton to 2486 yuan/ton, with a price drop of 0.05% during the period, a maximum amplitude of 2.73%, a month on month decline of 6.88%, and a year-on-year decline of 3.63%. At the beginning of the week, under the influence of crude oil and policies, the domestic methanol market fell sharply. After falling to a low level, many downstream and trading companies restocked at the low price. In addition, some major production areas experienced equipment failures and reduced production, supporting the low rebound of the domestic methanol market. The methanol market is fluctuating and running.
As of the close on April 11th, the closing price of methanol futures on Zhengzhou Commodity Exchange has fallen. The main contract 2505 for methanol futures opened at 2420 yuan/ton, with a highest price of 2424 yuan/ton and a lowest price of 2374 yuan/ton. It closed at 2392 yuan/ton in the closing session, a decrease of 1 yuan or 0.04% from the previous trading day’s settlement. The trading volume is 688075 lots, the position is 392146 lots, and the daily increase is 55072 lots.
In terms of cost, recently, the domestic chemical coal market has stopped falling and rebounded, showing positive changes in the market. The coal mines in the production area maintain normal production, and the overall supply is basically stable. After a brief rise in port prices recently, they have returned to a stagnant market. Downstream terminal inventories are high, and they are adopting a wait-and-see attitude towards market resources. The cost of methanol is influenced by favorable factors.
On the demand side, downstream acetic acid: the demand for acetic acid continues to decline; Downstream chloride: Increased demand for chloride; Downstream formaldehyde: Increased demand for formaldehyde; Downstream MTBE: MTBE demand increases; Downstream dimethyl ether: There are no plans to stop driving dimethyl ether next week, and the demand fluctuation is not significant. The majority of downstream demand for methanol has increased, and the demand for methanol is influenced by favorable factors.
On the supply side, the overall recovery exceeds the loss, resulting in an increase in capacity utilization. Negative factors affecting the methanol supply side.
In terms of external trading, as of the close of April 10th, the CFR Southeast Asian methanol market closed at $348.50-349.50 per ton, a decrease of $3 per ton. The closing price of the US Gulf methanol market is 92.00-93.00 cents per gallon; The closing price of FOB Rotterdam methanol market is 287.50-288.50 yuan/ton, down 10 euros/ton.
In the future market forecast, there is ample supply, and some factories still have shipment demand, with a slight increase in traditional downstream demand expected. The methanol analyst from Shengyi Society predicts that the domestic methanol spot market will mainly consolidate.

According to the Commodity Market Analysis System of Shengyi Society, this week’s PET (polyester bottle flakes) prices have shown a significant decline due to multiple pressures such as negative costs. As of April 11th, the average sales price of PET (polyester bottle flakes) is 5655 yuan/ton.
In terms of cost, factors such as OPEC+production increase, US tariff policies, and Iraq’s resumption of crude oil exports have put pressure on international oil prices. Brent crude oil has fallen below the key support level of $70 per barrel, weakening the cost support of the polyester industry chain. PTA and ethylene glycol prices have weakened. From April 1st to 11th, PTA prices fell from 4910 yuan/ton to 4489 yuan/ton, a decrease of 8.57%. Ethylene glycol prices also fell by more than 3%. In addition, port inventories have risen to a high of 584400 tons, and the operating rate of coal production facilities has remained above 70%. The loose supply pattern is difficult to change, and price rebound is limited.
In terms of supply and demand: In 2025, the new production capacity of polyester bottle flakes will be 2.15 million tons, and coupled with the current high inventory in the same period, market concerns about oversupply have intensified. The operating rate of major production enterprises remains at 74.48%, and the supply continues to increase. However, the demand side has not improved synchronously, resulting in an imbalance between supply and demand. In terms of exports, due to the global economic slowdown and environmental policy restrictions, the export increment is not enough to offset the domestic supply pressure.
In response to the current market situation, Shengyi Society believes that the core logic behind the significant drop in polyester bottle chip prices this week is the multiple pressures of cost collapse, oversupply, and weak demand. In the short term, the price of PET market may adjust with the cost side, and the actual trend still needs to pay attention to the subsequent equipment, demand situation, and cost support under the traction of crude oil.

The hydrofluoric acid market has been operating steadily this week. According to the analysis system of Shengyi Society, as of April 10th, the benchmark price of hydrofluoric acid in Shengyi Society was 12450 yuan/ton, an increase of 1.63% compared to the beginning of this month (12250 yuan/ton).
On the raw material side: The fluorite market for raw materials is weak and declining, while the sulfuric acid market price is stable. The fluctuation range on the cost side is limited and not too large. According to the analysis system of Shengyi Society, as of April 10th, the benchmark price of Shengyi Society’s fluorite was 3756.25 yuan/ton, a decrease of -0.50% compared to the beginning of this month (3775.00 yuan/ton).
On the demand side: Downstream is approaching the peak season for refrigerants, and some refrigerants are experiencing price increases. Coupled with policy encouragement in the refrigerant industry, demand is expected to achieve substantial growth. Fluorine chemical companies within quota control have strong confidence in raising prices in the refrigerant market. The prices in the foreign trade market have increased, and upstream products are mainly purchased on demand, which supports the hydrofluoric acid market.
Market forecast: In the near future, there will be a slight downward trend in the market price of raw material fluorite, which will alleviate the cost pressure on anhydrous hydrogen fluoride production enterprises. However, it is expected that the decline in raw material prices will not be too large. The downstream refrigerant market is good, and some product prices will rise, which will provide some support for the anhydrous hydrogen fluoride market. It is expected that the anhydrous hydrogen fluoride market will operate smoothly in the later stage, and more attention should be paid to the news of leading enterprises and market supply and demand.

According to the Commodity Market Analysis System of Shengyi Society, the toluene market fluctuated and rose from March 31 to April 7, 2025. On March 31st, the benchmark price of toluene was 6060 yuan/ton, and on April 7th, the benchmark price of toluene was 6230 yuan/ton, an increase of 2.81%. During this cycle, the trend of crude oil first rose and then fell. Last weekend, crude oil fell sharply, which dragged down the mentality of the spot market and weakened the market after the holiday. During the period, the pre holiday purchasing intentions of the disproportionation and oil blending industries in Shandong were relatively strong, and the sales situation in the region was good. The overall inventory of refineries was low, and their quotations were relatively firm. Overall, the toluene market showed an upward trend followed by a downward trend this week due to the impact of pre holiday purchasing intentions.
Cost wise: International crude oil futures plummeted on April 4th. The settlement price of the main contract for WTI crude oil futures in the United States was $61.99 per barrel, a decrease of $4.96 or 7.4%. The settlement price of the main Brent crude oil futures contract was $65.58 per barrel, a decrease of $4.56 or 6.5%. Affected by US tariff policies, oil prices have plummeted for two consecutive trading days, with WTI experiencing a cumulative drop of nearly $10. Investors are concerned about the risk of economic recession caused by the escalation of global trade conflicts. According to crude oil analysts from Shengyi Society, based on the subsequent impact of current US tariff policies, crude oil may enter a new cycle in the long term. The supply-demand balance may be disrupted and enter the process of rebalancing again. In the short term, given that countries are attempting to negotiate lower tariffs or impose retaliatory tariffs, tariffs may change and oil prices may fluctuate significantly in the short term.
Supply side:
Sinopec’s toluene enterprise is operating normally, with stable production of equipment and many products for personal use, resulting in stable production and sales. As of April 7th, East China Company quoted 6100 yuan/ton, North China Company quoted 6200 yuan/ton, South China Company quoted 6350-6450 yuan/ton, and Central China Company quoted 6200 yuan/ton.
Demand side:
On April 7th, the price of xylene in the petrochemical sales company was temporarily stable, and the current execution price is 7200 yuan/ton. This price is implemented in East China, North China, Central China, and South China. Yangzi Petrochemical, Zhenhai Petrochemical and other units are operating stably and selling normally, with a price reduction of 400 yuan/ton compared to March 28th. As of April 4th, the closing prices of the xylene market in Asia were $778-780 per ton FOB Korea and $803-805 per ton CFR China.
Market forecast: Affected by the news of US tariffs, the overall commodity market will weaken, crude oil prices will significantly decline, and the atmosphere in the spot market will be weak. In terms of supply, there have been more incoming goods from the East China region recently, and the overall market supply is relatively loose. On the demand side, the downstream overall maintains on-demand procurement, but the demand is urgent. Overall, the recent supply of toluene in the market has been relatively loose, and the spot market is under pressure. It is expected that the market will mainly operate steadily and weakly in the short term.

According to the Commodity Market Analysis System of Shengyi Society, the aggregated MDI market has been declining recently. The mainstream price for Shanghai goods (44V20, M20S, 5005) is 15900-16000 yuan/ton, while the mainstream price for domestic goods (PM200) is 16500-16600 yuan/ton. Currently, MDI devices in China are operating at medium to high loads, with fast market supply filling and downstream entry at low prices, resulting in average demand. Pre holiday replenishment has been basically completed, with a shortage of new orders and a lack of positive news to boost the market. It is expected that the aggregated MDI market will operate weakly in the short term.

According to the Commodity Market Analysis System of Shengyi Society, the price trend of acetic acid in March first increased and then decreased. As of March 31, the price was 2810 yuan/ton, which is an increase of 10 yuan/ton compared to the acetic acid price of 2800 yuan/ton at the beginning of the month, with a monthly increase of 0.36%.
As of the end of the month, the market price details of acetic acid in various regions of China in March are as follows:
Region/ On March 1st/ On March 11th/ March 31st
South China region/ 2950 yuan/ton/ 2925 yuan/ton/ 2800 yuan/ton
North China region/ 2750 yuan/ton/ 2825 yuan/ton/ 2710 yuan/ton
Shandong region/ 2750 yuan/ton/ 2880 yuan/ton/ 2750 yuan/ton
Jiangsu region/ 2730 yuan/ton/ 2740 yuan/ton/ 2625 yuan/ton
Zhejiang region/ 2950 yuan/ton/ 2950 yuan/ton/ 2850 yuan/ton
In early March, the price of acetic acid rose strongly, mainly due to the maintenance of some factory facilities, resulting in a decrease in the utilization rate of acetic acid production capacity. At the same time, the bidding prices of large factories in the northwest continued to rise, and the atmosphere in the market was bullish. The market trading direction was good, and the acetic acid quotation was adjusted upwards; In the second half of the year, as the maintenance equipment resumed operation, the market supply increased, but downstream entry enthusiasm was not high, market transactions were limited, and sales pressure from manufacturers continued to increase. Under the supply-demand game, the price of acetic acid continued to decline.
The methanol market on the raw material side is fluctuating and consolidating. As of March 31st, the average price in the domestic market was 2590 yuan/ton, a decrease of 1.49% compared to the beginning of the month price of 2629 yuan/ton. During the month, some methanol plants were shut down for maintenance, boosting the spot market. However, downstream traders are mainly observing and waiting, and their enthusiasm for purchasing goods is limited. There is insufficient support for favorable conditions in the market. At the same time, some areas have increased their supply of goods, leading to a weak downward trend in the methanol market due to active destocking.
Market forecast: Business analysts believe that the current trading atmosphere in the acetic acid market is relatively weak, with industry players mainly negotiating on demand. In the short term, the acetic acid market will continue to operate steadily, and some domestic manufacturers will release maintenance plans in the later stage, which will have a certain boost to the market. The sales pressure on the supply side will weaken. In the long run, the utilization rate of acetic acid production capacity next month will decrease, and the price of acetic acid in the future may rise strongly. Please pay attention to the follow-up situation downstream.

1、 Price trend
According to data monitored by Shengyi Society, as of March 31st, the average quotation price of domestic high-quality DMF enterprises was 4220 yuan/ton. Currently, the DMF market price is mainly stable, and the price is mainly stable.
2、 Market analysis
Recently, DMF prices have been running steadily. Currently, the downstream demand for DMF procurement atmosphere is average, with downstream essential procurement being the main focus. The overall market supply and demand are balanced, and the overall market is running steadily. The reference for DMF bulk delivery prices in East China is 4400-4550 yuan/ton in Jiangsu and 4450-4600 yuan/ton in Zhejiang.
3、 Future forecast
DMF analysts from Shengyi Society believe that the DMF market is expected to operate steadily with a moderate to strong trend in the short term.

According to the commodity market analysis system of Shengyi Society, the overall price of polyester filament has been weak due to the drag of long and short factors this month. At the end of the month, some companies alleviate inventory pressure and offer discounts on shipments through promotional offers. On March 31st, the mainstream polyester filament factories in Jiangsu and Zhejiang quoted POY (150D/48F) at 6800-7100 yuan/ton, polyester DTY (150D/48F low elasticity) at 8100-8350 yuan/ton, and polyester FDY (150D/96F) at 7100-7400 yuan/ton.
In terms of cost, international crude oil prices fluctuate due to the geopolitical situation and supply and demand expectations, with the settlement price of the main Brent crude oil futures contract fluctuating around $85 per barrel in March. The prices of upstream raw materials (PX, PTA, MEG) have all fallen across the board. At the end of March, the average price of PTA in the East China market was 4861 yuan/ton, a decrease of nearly 2% from the beginning of the month
In terms of demand, the traditional peak season of “gold, silver, and silver” did not perform as expected, with weak foreign trade orders and domestic sales mainly focused on replenishing inventory for essential needs. The release pace of spring and summer orders was slow, and the growth rate of polyester filament production capacity slowed down. However, the high operating rate (about 88%) led to inventory rising to a nearly three-year high, resulting in significant supply pressure in the industry.
Overall, the polyester filament market has been under triple pressure this month, including declining costs, weak demand, and high inventory levels. Prices have remained stable but slightly weak. In the future, it is important to focus on the trend of crude oil, the pace of terminal order recovery, and enterprise differentiation strategies. There is limited room for price rebound in the short term, and Business Society believes that the polyester filament market will continue to operate weakly in the short term.

According to the monitoring of the commodity market analysis system of Shengyi Society, the 1 # tin ingot market in East China rose this week (3.24-3.28), with an average market price of 276960 yuan/ton at the beginning of the week and 279770 yuan/ton at the end of the week, with a weekly increase of 1.01%.
Fundamentally, on Friday, Myanmar was suddenly hit by an earthquake. Although the direct impact on local supply was relatively limited, it cast a shadow over the prospects of resuming production in the Wa State. At the same time, mines in the Democratic Republic of Congo have been shut down and urgently need minerals from Myanmar to fill the gap. However, the impact of this earthquake is difficult to accurately quantify. Once the mine is damaged and collapses, the resumption of production this year may be in vain, and the supply gap is expected to further widen. The import volume of tin ore in China is expected to experience a significant decline, and the tight supply of domestic tin ore is difficult to effectively alleviate. The production of refined tin may show a downward trend, and the weekly operating rate data of Yunnan refined tin has also confirmed this concern.
On the demand side, the operating rate of downstream tin and solder enterprises in December showed a month on month upward trend, reaching 76%; The operating rate of lead-acid batteries in February decreased to 58.6% month on month. In addition, PVC production achieved a year-on-year increase of 1.8% in January and February; The production of flat glass in December decreased by 1.2% year-on-year.
This week’s domestic inventory is 9225 tons, an increase of 650 tons; Spot premium of 150 yuan; LME inventory is 3050 tons, with a slight accumulation of global inventory.
comprehensive analysis
In the short term, the trend of tin prices is relatively strong. Pay attention to the news of Myanmar tin mine resuming production.

Price trend: narrow fluctuations, mixed ups and downs
According to the monitoring of the commodity market analysis system of Shengyi Society, on March 27th, the average price of dichloromethane (DCM) in Shandong Province was 2385 yuan/ton, a monthly decline of 5.73%, falling to the lowest point of the month, and showing an overall range oscillation pattern:
-On March 10th, it fell to the low point of 2400 yuan/ton in the first round of the month (-5.14% compared to the beginning of the month);
-On March 19th, it rebounded to a monthly high of 2575 yuan/ton (+1.78% compared to the beginning of the month).
Analysis of influencing factors
1. Supply side: Stable operating rate, periodic manifestation of inventory pressure
-The average operating rate of the methane chloride unit remains at 80%, with sufficient supply.
-The competition among enterprises has intensified, and the two rounds of bidding sales at the end of the month have suppressed prices. Currently, there is a wide downward adjustment, and market trading has increased. The short-term deep decline space is limited.

2. Cost side: Both raw materials methanol and liquid chlorine are rising
-Methanol: Affected by fluctuations in local facilities, spot prices have slightly risen to 2679.17 yuan/ton (+1.9% from the beginning of the month).
-Liquid chlorine: The maintenance plan for the alkali plant in April has increased, and the expected tight supply will support prices. However, downstream procurement is cautious, and the supply-demand game continues.
3. Demand side: Mainly focused on rigid procurement, with refrigerant demand providing support
-The overall demand in downstream industries is weak, and many companies are buying stocks at low prices, resulting in weak high price transactions.
-The refrigerant R32 market is strengthening, coupled with price adjustments by leading companies and the launch of long-term agreement negotiations in the second quarter, the industry’s prosperity is recovering, indirectly benefiting DCM prices.
4. Import and export: export surge, import low
-Export: Accumulated export of 31700 tons from January to February 2025, with a year-on-year increase of 34% (single month year-on-year increase of 74.9% in February), with strong external demand easing domestic supply pressure.
-Imports: The cumulative imports from January to February were only 24 tons, a year-on-year decrease of 64.3%, with a weak impact on the domestic market.
Future prospects
The current market is intertwined with long and short factors:
-Advantages: Support from raw material costs, rebound in refrigerant demand, and growth in exports;
-Negative: Loose supply, downstream high price resistance, inventory digestion still takes time.
Overall, the short-term price of dichloromethane may continue to fluctuate within a certain range. If exports continue to increase or costs continue to rise, the price center is expected to slightly shift upward.
