The price of isooctanol fluctuated and rose in January

According to the Commodity Market Analysis System of Shengyi Society, as of January 16th, the price of isooctanol was 7033.33 yuan/ton, a fluctuating increase of 1.69% compared to the price of 6916.67 yuan/ton on January 1st. The equipment maintenance of the isooctanol enterprise has been completed, and the operating load of the isooctanol enterprise device has increased. The operating rate of isooctanol is 9.5%, and the supply of isooctanol is sufficient; The price of propylene has risen strongly, and the cost support of isooctanol has increased; The price of plasticizers has fluctuated and risen, with increased support from downstream demand for isooctanol. The cost of isooctanol has risen, coupled with increased supply and weak downstream support, resulting in fluctuating prices of isooctanol.
Isooctanol manufacturer starts production to improve
The production of isooctanol manufacturers has increased, with a production rate of about 95% for domestic isooctanol manufacturers. The weekly production of isooctanol in China is 76000 tons, and the production of isooctanol has increased. As a result, the supply of isooctanol has increased, and the upward momentum of isooctanol has weakened.
The cost of raw material propylene has significantly increased
According to the Commodity Market Analysis System of Shengyi Society, as of January 16th, the price of propylene was 6147.67 yuan/ton, a significant increase of 7.52% compared to the price of 5717.67 yuan/ton on January 1st. In January, the price of propylene increased significantly, and the support for raw material prices increased. The cost of isooctanol also rose, and the support for the increase in isooctanol prices increased.
Downstream plasticizer DOP prices fluctuate and rise
According to the Commodity Market Analysis System of Shengyi Society, as of January 16th, the DOP price was 7492.50 yuan/ton, a fluctuating increase of 2.27% compared to the DOP price of 7325.84 yuan/ton on January 1st. The cost of DOP is rising, and the operating load of plasticizer DOP enterprises is stable, with an operating rate of about 63%. DOP production is stable, but the demand for isooctanol still exists, and the price increase of isooctanol provides significant support.
Future expectations
According to the data analyst of Business Society’s octanol product, in terms of cost, the price of raw material propylene has significantly increased, and the driving force for the rise of isooctanol has increased. In terms of supply, the operating rate of isooctanol enterprises has increased, and the supply of isooctanol has increased; In terms of demand, DOP enterprises are operating steadily, DOP production is stable, and there is still support for isooctanol demand. In the future, the cost support for isooctanol will increase, coupled with limited demand support due to increased supply. There is still significant downward pressure on isooctanol and upward support. It is expected that the price of isooctanol will fluctuate and stabilize in the future.

In the first half of January 2026, the domestic dichloromethane market showed a trend of first suppression and then rebound, with strong fluctuations. The core logic is “supply contraction+cost increase+rigid demand bottoming out”. According to the monitoring of the commodity market analysis system of Shengyi Society, as of January 15th, the average price of dichloromethane dispersed water in Shandong Province was reported at 1732 yuan/ton, an increase of 2.06% from the beginning of the month.
On the supply side, high construction rates and expected destocking support a rebound in prices
After the return of New Year’s Day, the operating rate of methane chloride plants remained at a high level of 81%. The main enterprises were operating at full capacity, and the market supply was under pressure. Enterprises voluntarily lowered prices to reduce inventory. In the middle of the year, the operating rate of the equipment gradually decreased to 75.8%. Some enterprises experienced fluctuations in equipment load, industry supply elasticity contracted, inventory pressure eased, and the willingness of enterprises to raise prices increased, driving continuous price recovery.
Cost side: Dual increase of methanol and liquid chlorine, strengthening the cost support line
Methanol: Expected decrease in import volume coupled with significant destocking at ports. As of January 15th, the benchmark price of methanol in Shengyi Society was 2269.17 yuan/ton, an increase of 2.79% from the beginning of the month. Liquid chlorine: downstream stable receipt of chlorine consumption, the ex factory quotation of tank trucks in Shandong region has risen to 300-400 yuan/ton, and the cost pressure on methane chloride enterprises has increased, driving up the price of dichloromethane.
Demand side: Rigid demand supports the bottom
The procurement of essential goods remains stable, and some enterprises’ replenishment operations have driven local transaction volume to increase.
Future outlook:
Supply side operating rate or stability, inventory controllable; On the cost side, methanol and liquid chlorine tend to fluctuate strongly, and cost support continues. On the demand side, attention should be paid to the stocking pace before the Spring Festival, regional weather conditions, and whether the Spring Festival logistics will shrink. It is expected that dichloromethane will maintain stability or operate in a narrow range, making it difficult to support a significant price increase.

This week, the domestic fluorite price trend was mainly volatile. As of the weekend, the average domestic fluorite price was 3406.25 yuan/ton, slightly higher than the early week price of 3400 yuan/ton by 0.18%, and a year-on-year decrease of 5.48%.
Supply side: Normal inventory of fluorite spot remains high
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 still tight, and backward mines will continue to be eliminated. In terms of new mines, mineral investigation work is still difficult. In addition, the national department needs to reform fluorite mines, and fluorite mining enterprises are facing increasingly strict safety and environmental protection requirements. The difficulty of operating fluorite mines has increased. However, the spot supply in the fluorite field is normal, and social inventory continues to operate at a high level without obvious signs of depletion. The supply side maintains a stable production rhythm. In addition, production activities will slow down before the end of the year, and the scale of periodic replenishment will shrink. Recently, downstream procurement is not active, and fluorite shipments are generally average. The fluorite market trend is stable.
Demand side: Hydrofluoric acid price stable, refrigerant market average
This week, the domestic price trend of hydrofluoric acid is temporarily stable, and the mainstream price of hydrofluoric acid discussed in various regions of China is 12000-12500 yuan/ton. The downstream hydrofluoric acid equipment is still in shutdown, 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, while hydrofluoric acid enterprises are in a loss making state. Recently, hydrofluoric acid merchants have not been actively purchasing, and the fluorite market is in a fierce game between supply and demand, falling into a “price but no market” deadlock. Despite being in the traditional stocking stage of downstream refrigerant and other industries, the high prices have suppressed procurement demand, thereby affecting the digestion rhythm of upstream raw materials. Fluorite prices have not changed much.
The overall stability and operation of the terminal refrigerant market have been maintained, and the terminal policies of the refrigerant industry have been 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, and downstream channels mainly focus on stocking up for essential needs. Industry inventory has dropped to a low level in nearly two years; The supply side is constrained by the quota system, coupled with a highly concentrated industry share pattern, and market confidence remains stable. However, caution is still held towards upstream procurement, with a focus on maintaining stable prices in the fluorite market.
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, the high inventory of fluorite spot goods, downstream hydrofluoric acid enterprises mainly purchase on demand, and demand has not actually improved. The fierce game between supply and demand, overall, the fluorite market price is mainly volatile in the short term.

1、 Market situation:
Recently, the domestic acrylic acid market has indeed shown typical characteristics of “supply and demand game, stability maintenance and consolidation”. The market shows stable prices, but there are different pressures and supports on both the supply and demand sides. As of January 6th, the benchmark price of acrylic acid in Shengyi Society was 5850.00 yuan/ton, unchanged from the beginning of this month.
2、 Supply and demand ends:
The current market deadlock is the result of the balance of power between supply and demand
Supply side:
The industry’s operating rate is not only high, but also the price trend has been stable since early January, which has brought abundant spot resources to the market and is the main factor suppressing price increases.
Demand side:
The core support of the market only comes from the rigid demand procurement of downstream users. Due to issues such as slow capital collection in the terminal fields (such as coatings and textiles), there is generally low interest in traditional “winter storage” stocking before the Spring Festival, and most purchases are made in small quantities and on demand. This has led to a sluggish overall trading atmosphere in the market, which cannot provide upward momentum for prices.
Cost side:
The prices of propylene and n-butanol, the main upstream raw materials, have been steadily rising recently, and the overall cost support for acrylic acid is still acceptable but lacks strong driving force, failing to break the balance of supply and demand game. As of January 6th, the benchmark price of propylene in Shengyi Society was 5744.33 yuan/ton, an increase of 0.47% compared to the beginning of this month (5717.67 yuan/ton).
On January 6th, the benchmark price of n-butanol (industrial grade) in Shengyi Society was 5633.33 yuan/ton, unchanged from the beginning of this month.
3、 Future outlook:
Overall, the market is expected to maintain a narrow consolidation trend in the short term. The combination of high supply and weak stocking demand creates a “ceiling” for price increases. The current high demand and high costs have also set a “floor” for prices, making it difficult for them to fall deeply.
The key points for the future are whether the downstream stocking pace before the Spring Festival will be activated due to the passage of time, and whether there will be unexpected adjustments in the supply side’s operating rate. These two points will be the main variables that break the current balance and guide the market direction.

In 2025, the overall trichloromethane market in China showed a fluctuating downward trend, with a slight rebound towards the end of the year
From January to February at the beginning of the year, the maintenance and supply of trichloromethane equipment in some enterprises were tight. In addition, downstream enterprises restarted their quotas at the beginning of the year, and downstream stocking was active, resulting in short-term concentrated release of demand. As a result, the price of trichloromethane skyrocketed to 2800 yuan/ton.
From March to July, on the one hand, new production capacity was gradually released, while the demand for the core downstream refrigerant R22 continued to be weak, leading to a sharp increase in supply pressure. Enterprise inventories remained high, and the price of trichloromethane fell to the lowest of 1533 yuan/ton this year.
From August to October, on the one hand, the price of methanol raw materials weakened, and the cost support of trichloromethane collapsed; On the other hand, downstream demand is weak and prices are weakly declining. During this period, some companies underwent brief maintenance to alleviate supply pressure, which to some extent eased the downward pressure on prices.
The tightening of regional supply and low inventory levels in November and December, coupled with the release of some demand at the end of the year, have driven prices to stop falling and slightly rebound. The price of trichloromethane has rebounded to around 1966 yuan/ton.
The price fluctuation of trichloromethane in 2025 is mainly affected by the following factors:
1. Supply pressure continues to increase: By 2025, new production capacity will be released in the industry, and the overall supply level will improve. Meanwhile, as an important “chlorine consuming” product, the methane chloride plant maintains a high operating rate even when operating at a loss, exacerbating the situation of oversupply in the market. The first phase of the 200000/ton methane chloride unit of Hunan Hengyang Jindong Technology Co., Ltd. was put into trial operation at the end of March 2025 and achieved stable operation in October 2025. The average annual operating rate of methane chloride in China in 2025 is around 7.8%, with relatively low centralized maintenance and operation of large factories in the first and fourth quarters, and relatively high operation in the peak season of the second and third quarters.
2. The downstream demand structure is single and weak: over 90% of the demand for trichloromethane relies on refrigerant R22. However, the quota for R22 in 2025 has been reduced, and its terminal demand (such as fluoropolymers) has performed poorly, resulting in low enthusiasm for enterprise production and weak support for the procurement of raw material trichloromethane.
3. Constraints of cost and loss: Cost determines the “bottom”: When the market price of chloroform falls below or exceeds the cost line of “methanol+manufacturing costs”, enterprises without supporting advantages will fall into cash losses, be forced to reduce production or stop production, thereby providing rigid bottom support for prices. From the overall trend of trichloromethane in 2025, the price dropped to around 1533 yuan/ton in June and July 2025, reaching this bottom line. Overall, when demand is still acceptable, cost fluctuations can be effectively transmitted to selling prices. When demand is severely insufficient, cost can only define the bottom of price decline and the depth of losses, and cannot drive a trend upward trend.

Market Outlook for 2026
Overall, it is expected that the trichloromethane market will continue to operate under pressure in 2026, and there will be no trending upward trend
On the supply side, the pattern of overcapacity is expected to continue. The slight increase in methane chloride production capacity in 2025 means that there will not be many new methane chloride plants added in the future. Currently, only Gansu Juhua New Materials Co., Ltd. has a 760000 tons/year methane chloride plant to be built. The expected production of trichloromethane in 2026 is about 1.05-11 million tons, with an operating rate of 70-75%. Overall loose supply
In terms of demand, the quota for the core downstream refrigerant R22 continues to be compressed, resulting in a 3-5% decrease in demand and a decrease in its proportion from 45% in 2025 to 40-42% in 2026. Its demand growth space is limited, and it will continue to be a key factor restricting the trichloromethane market. The growth of market demand will rely more on fluorinated polymer materials (such as PTFE), fourth generation new refrigerants (such as HFOs), and fine chemical industries such as pharmaceutical and pesticide intermediates.
Price trend: With the expectation of abundant supply, the overall price center of gravity may be difficult to rise significantly, and it is expected to continue to fluctuate at a low level. The fluctuation range of its price will be affected by specific factors such as changes in the cost of raw materials methanol and liquid chlorine, as well as downstream stage replenishment demand. Overall, the bottom line of trichloromethane prices in 2026 will still be constrained by costs. The central price range for methanol in 2026 may be between 2100-2300 yuan/ton, while the price for liquid chlorine may be between 50-250 yuan/ton. The bottom line support for trichloromethane costs will continue. In addition, due to supply and demand maintenance and other factors, it is expected that the price of trichloromethane will fluctuate between 1800 and 2300 yuan/ton in 2026.

According to the Commodity Market Analysis System of Shengyi Society, the xylene market will first rise and then fall in December 2025, with an overall upward trend. From December 1st to 30th, the domestic xylene market price increased from 5470 yuan/ton to 5510 yuan/ton, with a cumulative price increase of 0.73% during the period.
In the first half of the year, the domestic mixed xylene market showed a moderate upward trend, and Shandong, as a core production area, had good refinery shipments, providing stable support for the regional market; The markets in East and South China have kept up with the rise, and the quotations of major refineries such as Sinopec have remained stable. The market negotiation atmosphere is still acceptable. The downstream oil and chemical industry continues to adopt the strategy of replenishing inventory according to demand, maintaining a neutral level of procurement enthusiasm, and there has been no large-scale hoarding or reduction of inventory, supporting a slight increase in prices.

In the latter half of the year, the domestic mixed xylene market showed a moderate upward trend, and Shandong, as a core production area, had good refinery shipments, providing stable support for the regional market; The markets in East and South China have kept up with the rise, and the quotations of major refineries such as Sinopec have remained stable. The market negotiation atmosphere is still acceptable. The downstream oil and chemical industry continues to adopt the strategy of replenishing inventory according to demand, maintaining a neutral level of procurement enthusiasm, and there has been no large-scale hoarding or reduction of inventory, supporting a slight increase in prices.
Cost wise: In December 2025, the domestic crude oil market showed a volatile downward trend, with narrow fluctuations in the first half of the year. The news of OPEC’s slight increase in production in December and the suspension of production in the first quarter of 2026 briefly boosted market sentiment, but failed to reverse the loose pattern. Domestic port commercial crude oil inventories increased by 1.67% month on month, and supply pressure began to emerge. After mid month, concerns about global crude oil oversupply intensified, with Brent crude falling below $60 per barrel, driving the domestic market to follow suit. Although geopolitical events such as the escalation of US sanctions on Venezuela triggered a short-term rebound during this period, it was difficult to change the trend. As the end of the year approaches in the latter half of the year, market trading activity has decreased under the pressure of capital recovery. The operating rate of domestic main refineries is sluggish, and the weak trend of terminal demand has not changed, further suppressing oil prices and presenting a fundamental driven downward trend throughout the process. As of the 26th, the settlement price of the February WTI crude oil futures contract in the United States was $56.74 per barrel, and the settlement price of the February Brent crude oil futures contract was $60.60 per barrel.
Supply side:
Sinopec’s xylene quotation summary shows that the company is currently operating normally, with stable production and sales. The company’s quotation remains unchanged from the previous day. As of December 30th, East China Company quoted 5500 yuan/ton, North China Company quoted 5200-5300 yuan/ton, South China Company quoted 5650-5700 yuan/ton, and Central China Company quoted 5250-5450 yuan/ton..
Demand side: Downstream on-demand procurement shows overall weakness
The domestic oil and chemical industry continues to adopt the strategy of replenishing inventory according to demand, with low purchasing enthusiasm and no centralized replenishment behavior, which has limited effect on driving prices. The PX market has become the main bearish factor, with significant fluctuations in the December contract price of PX on the Zhengzhou Commodity Exchange in the latter half of the month. The closing price on the 29th was 7208 yuan/ton, a significant drop from the mid month high, and the mixed xylene price was under pressure and weakened due to cost transmission.

According to the Commodity Market Analysis System of Shengyi Society, as of December 30th, Sinopec Sales Company has implemented a price of 7000 yuan/ton, and the four major regions of East China, North China, Central China, and South China have uniformly implemented this price; The main facilities of Yangzi Petrochemical and Zhenhai Petrochemical are operating stably, and the sales of products are normal. The current price has increased by 150 yuan/ton compared to November 28th.
In terms of international markets, as of December 29th, the closing prices of the xylene market in Asia were $867-869/ton FOB Korea and $892-894/ton CFR China, an increase of $66/ton from November 27th.
Market forecast: Currently, the domestic mixed xylene market is in a game of bullish and bearish factors: on the one hand, the supply side equipment is operating stably, the supply of goods is abundant, and the shipment situation of refineries in core production areas such as Shandong is good, providing basic support for the market; On the other hand, the lack of clear upward momentum in international crude oil and the unchanged pressure on the PX market, coupled with weak downstream demand, have suppressed prices. Overall, the mixed xylene market lacks a strong driving force for sustained upward or downward movement in the short term, and is expected to maintain a narrow range of fluctuations. It is necessary to focus on improving the demand side and the impact of PX market transmission.

1、 Price trend

Taking sulfuric acid method rutile titanium dioxide, which has a large volume of goods in the domestic market, as an example, according to data monitoring by Business Society, the price of titanium dioxide in the domestic market increased in December. On December 1st, the average price of titanium dioxide was 13500 yuan/ton, and on December 26th, the average price of titanium dioxide was 13740 yuan/ton, with a price increase of 1.78%.
2、 Market analysis
The domestic titanium dioxide market price will increase in December. In the first half of the year, titanium dioxide companies faced significant cost pressure and continued to raise prices last month. The mid market situation is generally wait-and-see, and the titanium dioxide market is in a stalemate. In the latter half of the year, several titanium dioxide companies sent letters again to raise the price of titanium dioxide. As of now, the domestic quotation for sulfuric acid based pyrite type titanium dioxide is mostly between 12900-14300 yuan/ton; The price of Ruiti type is around 12200-12700 yuan/ton, and the actual transaction price is negotiable.
According to customs data statistics, China’s imports of titanium dioxide in November 2025 were approximately 5300 tons, a year-on-year decrease of 20.29% and a month on month decrease of 5.37%. The average monthly import price was $3083 per ton, a month on month decrease of 3.98%.
According to customs data statistics, China’s titanium dioxide exports in November 2025 were approximately 152000 tons, an increase of 1.96% year-on-year and 3.97% month on month. The monthly average export price was 1877 US dollars/ton, a decrease of 0.18% month on month.
3、 Future forecast
The titanium dioxide analyst from Shengyi Society believes that this month’s production costs have had a significant impact, putting pressure on titanium dioxide manufacturers. The market has seen two consecutive rounds of price increases, and manufacturers have shown a positive attitude towards price hikes. The market is still accepting new order quotes. It is expected that the market will operate steadily and positively in the short term, and the actual transaction price will be negotiable.

The price trend of domestic epoxy propane market has declined this week. According to the monitoring system of Shengyi Society, as of December 19th, the benchmark price of Shengyi Society’s epoxy propane was 7850 yuan/ton, an increase of 1.29% compared to December 1st.

Price influencing factors:
Raw material side: This week, the price of raw material propylene has slightly fallen, and the cost side support is insufficient, resulting in a decrease in the market price of epoxy propane. According to the market analysis system of Shengyi Society, as of December 19th, the benchmark price of propylene in Shengyi Society was 6115.75 yuan/ton, a decrease of 1.05% compared to the beginning of this month (6180.75 yuan/ton).
Supply side: Some major manufacturers of epoxy propane have gradually released their production capacity, easing the tight supply situation. Currently, there is sufficient inventory, and downstream procurement follow-up is insufficient, resulting in a downward trend in epoxy propane prices.
Demand side: Downstream demand side procurement sentiment is cold, market transaction orders are limited, small orders are mainly for first-time purchases, the trading atmosphere of epoxy propane enterprises has weakened, and shipments are not smooth. It is expected that the epoxy propane market will mainly operate in a stable to weak manner in the later stage.
Market forecast:
Business Society’s epoxy propane analyst believes that the support for the decline in raw material propylene market prices has weakened, downstream demand side purchasing enthusiasm has weakened, and epoxy propane shipments are not smooth. In addition, with the gradual release of production capacity by some enterprises and sufficient inventory, it is expected that the epoxy propane market will operate steadily and weakly in the short term, and more attention should be paid to changes in raw material prices and market supply and demand.

According to the Commodity Market Analysis System of Shengyi Society, the TDI market in East China has shown a strong upward trend this week. As of December 12th, the average market price in East China was 14866 yuan/ton, and on December 8th, the average price was 14666 yuan/ton, with a weekly increase of 1.36% and a year-on-year increase of 15.25%.
The TDI market maintained its upward trend this week. As of this Friday, the domestic offer price for TDI in East China is between 14400-14800 yuan/ton; The Shanghai cargo offer price is around 14800-15000 yuan/ton. The market supply remained tight during the week, with frequent news of price increases and tight supply from major manufacturers. The supplier’s attitude towards price increases, while traders maintain a stable flow of goods. Constrained by the flat and weak demand, the TDI market tends to be strong and push up.
Supply side: Fujian Wanhua TDI plant operates with reduced load; Shanghai Kesichuang TDI plant shutdown maintenance; A TDI unit in South China is experiencing abnormal conditions and is expected to be shut down for at least a week.
Cost aspect: The toluene market is temporarily stable, with relatively calm market trading and flat demand. The market will remain stable this week.
In terms of future analysis, TDI data analysts from Shengyi Society believe that the downstream market has a clear resistance to high priced goods and is cautious in entering the market, which makes it difficult to increase trading volume. The supply side continues to heat up, and it is expected that the TDI market will have a strong trend in the short term.

This week, the domestic phenol market experienced a wide decline. Sinopec’s listing price in East China will be lowered by 300 yuan per ton within the week, with an execution of 6000 yuan per ton. According to data monitored by Shengyi Society, from the perspective of the East China market, the domestic phenol market price was 6163 yuan/ton on December 1st and 5760 yuan/ton on December 5th, a decrease of 6.54%.

From a supply perspective, the inventory of phenol at Jiangyin Port was around 10000 tons at the beginning of the week. Imported and domestic cargo were replenished during the week, but the impact on spot goods was not significant. Overall, the market supply is sufficient, and traders are actively lowering prices for shipments.
From the demand side perspective, downstream terminal enterprises have limited participation in market inquiries. The main reason for the bearish market this time is also that the demand side is difficult to release, and the expectation of breaking the six point threshold has been released ahead of schedule. Factories have significantly lowered their listing prices, causing the market’s low points to be continuously refreshed this year. Currently, the market is affected by low prices, resulting in insufficient transactions and further decline in the center of gravity.
Business Society predicts that the phenol market will operate at a low level. Overall, cost fluctuations have little impact on the phenol market, and the current tight supply-demand relationship is the main factor driving the phenol market to continuously hit new lows this year. From the supply side, there may be parking plans for Yangzhou Shiyou next week, and the overall replenishment of domestic trade cargo is stable; On the demand side, overall procurement is based on demand, with small orders being the main focus, and downstream overall demand is unlikely to change significantly.
