In the first half of 2025, the import volume of acetone in China was 218000 tons, a year-on-year increase of 56.5%. During this period, the highest import volume in May was 44800 tons, and the lowest import volume in June was 21500 tons. In the second half of 2025, China’s acetone production capacity is expected to increase by 510000 tons, with further growth in domestic production and a continuous improvement in self-sufficiency rate. However, the import source of goods is still showing an upward trend.
In 2025, the top four trading partners of importing countries will still be Saudi Arabia, Thailand, Taiwan, China, and South Korea. Starting from 2025, Singapore’s import volume of acetone will increase, with acetone import contracts mainly focused on Saudi Arabia and Thailand. Although the phenol ketone plant in Saudi Arabia began to shut down for maintenance in April, the incoming goods to China still arrived normally, resulting in a significant increase in overall imports from January to May. However, the import volume has decreased year-on-year since June.
In the second half of 2025, China’s acetone production capacity is expected to increase by 510000 tons, and the import sources are mainly operated through contracts. The Saudi Arabian plant will start to shut down for maintenance in April, and the contracts for July and August cannot be supplied normally. The contracts for Thailand have arrived normally. The downstream deep processing industry of acetone still has capacity expansion. In June, the anti-dumping policy of acetone was terminated, and the supply of South Korea, Taiwan, China or China arbitrage in the future, so the import volume showed a trend of growth. Overall, it is estimated that the annual import volume of acetone in 2025 will reach 400000 tons.

According to the commodity analysis system of Shengyi Society, the domestic TDI market continued to rise in July. As of July 22, the average price of TDI in East China was 15333 yuan/ton, an increase of 30.68% from 11733 yuan/ton on July 1.
Device malfunction and centralized maintenance triggered TDI supply crisis
Device malfunction, limited supply
On July 12th, Covestro’s factory in Domagen, Germany was affected by an electrical fire, causing force majeure in the production of caustic soda, chlorine gas, and hydrochloric acid. The loss could not be fully compensated by delivery from other factories, and the duration could not be predicted at this time. This directly led to the declaration of force majeure supply for TDI equipment with an annual output of 300000 tons. This accident directly led to an increase in domestic TDI prices. Due to a surge in overseas orders, Shanghai Covestro suspended reporting, and Wanhua’s quotation continued to rise. On July 18th, a major northern factory announced a price increase of 4500 yuan to 18500 yuan/ton for direct sales channels, with a daily increase of over 30%.
At the same time as the overseas equipment changes, the domestic TDI equipment undergoes centralized maintenance, further exacerbating the TDI supply crisis. Two sets of equipment in the northwest region have entered maintenance successively, with one set shut down for 35 days from July 16th, and the scattered water supply has been completely interrupted; The other set will be inspected 10-15 days in advance until the end of July. The 350000 ton/year TDI unit of Wanhua Hungary began routine maintenance on July 19th and is expected to last for about 30 days. The total production capacity of the affected facilities in recent times is 1.52 million tons, accounting for about 40% of the global production capacity.
Export market exceeds expectations
In May 2025, China’s TDI export volume reached 51600 tons, setting a new monthly record high and soaring by 98.45% year-on-year. In June 2025, the export of TDI was 48000 tons, an increase of 81.62% compared to the same period last year. Under the continuous growth of TDI production capacity in China, the contraction of production capacity in Europe and America, and the stimulation of tariff policies, TDI export market orders have surged. The second round of force majeure events in Germany’s Covestro will affect production capacity by 300000 tons, accounting for 55% of Europe’s total production capacity, which will further stimulate the growth of TDI exports.
Future forecast
As of now, the high price of TDI has exceeded 16000 yuan/ton. After multiple price jumps, some intermediaries have entered a state of closed trading and suspended reporting, and some have increased their willingness to ship. End users just need to buy, but placing high priced orders is not satisfactory. Considering the synchronous maintenance of multiple TDI devices and the fact that some of them still have maintenance plans in the future, the supply is expected to remain tight. It is expected that the TDI market will continue to rise in the short term, and we will closely monitor the changes in supply and demand in the future,

According to the Commodity Market Analysis System of Shengyi Society, the domestic natural rubber spot market has seen a significant upward trend in recent times (7.9-7.22). As of July 22, the spot rubber market in China was around 15108 yuan/ton, an increase of 8.63% from 13908 yuan/ton on the 9th. Downstream tire production has slightly increased, providing support for rubber demand; The raw material prices have slightly increased, and the cost is supported by natural rubber; The slight fluctuations in port inventory but still at a high level have put some pressure on the natural rubber market.

As of July 18th, the construction of semi steel tires by domestic tire companies has slightly increased to around 7.5%; The construction of all steel tires by tire companies in Shandong Province has slightly increased to around 6.5%.
Market forecast: Currently, domestic and international raw material prices are running at high levels, providing support for the Tianjin rubber market. Downstream production has slightly increased, providing strong support for natural rubber demand. Tianjin rubber port inventory remains at a high level; Overall, it is expected that the natural rubber market will mainly fluctuate at a high level in the later stage.

The operating load of equipment in plasticizer enterprises has decreased, and the demand support for phthalic anhydride has weakened. Due to sufficient supply and decreasing demand, the price of phthalic anhydride fluctuated and fell this week.
The cost support of phthalic anhydride still exists, and the supply is decreasing
Sinopec’s quotation for ortho benzene is 7000 yuan/ton. The price of industrial naphthalene is fluctuating and stabilizing, while the cost support of phthalic anhydride still exists. This week, the maintenance of phthalic anhydride equipment has decreased, and the operating rate of enterprises has increased to 6.5%. The supply of phthalic anhydride is sufficient. The supply is sufficient, and the support for the rise in phthalic anhydride prices this week has weakened.
Demand side: DOP prices first fell and then rose
According to the Commodity Market Analysis System of Shengyi Society, as of July 18th, the DOP price was 8109.16 yuan/ton, a decrease of 0.82% compared to the DOP price of 8175.84 yuan/ton on July 11th; Compared to the DOP price of 8017.50 yuan/ton on July 15th, it has increased by 1.14%. This week, the resumption of DOP production has been slow, and the operating rate of the plasticizer DOP industry has increased to 46%. The production of plasticizers has increased, and the price of plasticizers has first fallen and then risen. The production of plasticizers has increased, the demand for phthalic anhydride has grown, and the support of rising phthalic anhydride prices still exists.
Future forecast
According to the data analyst of Shengyi Society’s phthalic anhydride products, in terms of demand, plasticizer companies have increased their production and output, leading to an increase in demand for phthalic anhydride; In terms of supply, phthalic anhydride enterprises have extensive experience in equipment maintenance and sufficient supply of phthalic anhydride. In the future, with sufficient supply and increasing demand, it is expected that the price of phthalic anhydride will remain weak and consolidate at a low level.

According to the Commodity Market Analysis System of Shengyi Society, the domestic price of polyester staple fiber showed a weak trend this week (July 14-18). As of July 18, the average market price of domestic polyester staple fiber (1.4D * 38mm) was 6643 yuan/ton, a decrease of 0.36% from the beginning of the week.
The international crude oil market is currently characterized by loose supply and poor demand, coupled with the overall easing of the geopolitical situation compared to the previous period, which has limited support for oil prices and mainly led to fluctuating adjustments. As of July 17th, the settlement price of the August WTI crude oil futures contract in the United States was $67.54 per barrel, and the settlement price of the September Brent crude oil futures contract was $69.52 per barrel.
The PTA market as a whole maintained a weak trend. As of July 19th, the average price of PTA in the East China region was 4776 yuan/ton, a decrease of 0.28% from the beginning of the week. In the second half of the week, prices rose slightly due to the boost of crude oil. The supply remains stable, there are no new changes in the equipment, and the overall operating rate of the industry is around 80%. Among them, the 2 million ton plant of Yisheng Hainan reduced its load on July 1st due to some reasons, and increased its load on July 6th. In June, the 4.5 million ton plant of Fuhai Chuang and the 2.5 million ton plant of Dongying Weilian were still shut down.
The terminal has entered the seasonal off-season, and the downstream yarn market remains weak, resulting in a lack of enthusiasm for raw material procurement. The high inventory, shortage of orders, and losses in the weaving industry have led to a continued decline in load to below 56%. Textile export orders continue to decline, dragged down by sluggish demand.
Business analysts believe that the traditional off-season terminal negative feedback continues, and the market buying and selling atmosphere is flat. Insufficient cost support and weak demand have resulted in poor performance, and it is expected that the price of polyester staple fibers will continue to remain weak.
