1、 Price trend
Taking the sulfuric acid method for producing pyrite type titanium dioxide, which has a large volume of goods in the domestic market, as an example. According to data monitoring from Shengyi Society, the domestic titanium dioxide market has remained stable this week, with an average price of 13860 yuan/ton.
2、 Market analysis
This week, the domestic titanium dioxide market has temporarily stabilized and consolidated. At present, the demand for titanium dioxide in the market is average, with high raw material production costs and significant operational pressure on enterprises. However, downstream procurement enthusiasm is not high, and new orders signed are not as expected. The upstream and downstream markets are in a game, and the market situation is relatively stagnant, with many people waiting and watching. As of now, the domestic quotation for sulfuric acid based pyrite type titanium dioxide is mostly between 13200-14200 yuan/ton; The price of rutile type is around 12000-12500 yuan/ton, and the price of chlorination method is 13600-16500 yuan/ton. The actual transaction price is negotiable.
3、 Future forecast
Business Society’s titanium dioxide analyst believes that the domestic titanium dioxide market will mainly consolidate this week. The upstream and downstream market conditions are relatively stagnant, and the market is observing and cautious in transactions. It is expected that titanium dioxide will operate steadily in the short term, and the actual transaction price will be negotiated one by one.

This week, the polyester filament market as a whole showed a weak downward trend, with a slight shift in price focus. As of October 17th, the mainstream polyester filament factories in Jiangsu and Zhejiang have quoted POY (150D/48F) at 6400-6700 yuan/ton, polyester DTY (150D/48F low elasticity) at 7750-8000 yuan/ton, and polyester FDY (150D/96F) at 6500-6800 yuan/ton.
Weakened cost support
The recent decline in international oil prices has weakened the cost support of polyester filament. At the same time, market concerns about US tariff policies have intensified market panic.
Rising inventory pressure
After the National Day holiday, the inventory of polyester filament continued to accumulate. As of October 9th, the average inventory in the industry has reached about 22 days, including POY for about 13-14 days, FDY for about 24 days, and DTY for about 29 days. High inventory levels make factories strongly willing to ship, and they tend to alleviate pressure by offering discounts and promotions.
The demand side continues to be sluggish
Downstream weaving enterprises are very cautious in procurement, mainly focusing on replenishing inventory for essential needs, and have a weak willingness to stock up in large quantities. At the same time, there is also uncertainty in the external trade environment. Although Trump’s attitude has softened after his tough stance, the high comprehensive tariff rate still poses a challenge to the sustained recovery of textile export orders.
Considering factors such as insufficient cost support, high inventory, and low downstream purchasing willingness, it is expected that the price of polyester filament will continue to fluctuate weakly in the short term. The prices of some varieties with high inventory pressure may continue to decline slightly.

Product Name: Isopropanol
Latest price: On October 16th, the average market price was 5841.67 yuan/ton.
Key analysis points: The focus of today’s isopropanol market trend is downward. The confidence in the market is average, with downstream acetone market prices fluctuating at low levels and insufficient cost support, suppressing the mentality of industry players. Purchasing is on demand, and transactions are cautious. Overall, the market enthusiasm is poor and the focus of negotiations is weak.
It is expected that the isopropanol market will weaken and consolidate in the short term, and attention should be paid to the trend of the raw material market.

According to the Commodity Market Analysis System of Shengyi Society, domestic lithium carbonate has shown a narrow range of fluctuations recently. As of October 15th, the benchmark price of domestic battery grade lithium carbonate spot trading society was 73016 yuan/ton, up 1.95% month on month and down 10.3% year-on-year; The benchmark price for domestic industrial grade lithium carbonate spot trading is 71166 yuan/ton, up 1.93% month on month and down 9.69% year-on-year.
Supply side: pressure and support coexist
The overall supply side presents a situation where pressure and support are intertwined. On the one hand, supply pressure still exists: domestic lithium carbonate production continues to grow, and it is expected that the production may exceed 90000 tons in October, which will exert a certain pressure on market prices.
On the other hand, Chilean customs released export data showing that the total export of lithium carbonate from Chile in September 2025 was 15918 tons, a decrease of 5.83% compared to the previous month and 12.74% compared to the previous year. Among them, 11101 tons were exported to China, a decrease of 14.5% compared to the previous month and 33.1% compared to the previous year. To some extent, it reduces the increase in market supply.
Demand side: resilience and hidden concerns intertwined
On the demand side, there is a characteristic of both support and hidden concerns. In the field of power batteries, demand remains resilient. With the continuous development of the new energy vehicle industry, the penetration rate of new energy vehicles has steadily increased, driving the growth of demand for power batteries and providing certain support for the demand for lithium carbonate.
However, the escalation of trade frictions between China and the United States has also increased the uncertainty of export orders for lithium carbonate and downstream products such as energy storage batteries, further putting pressure on the demand side.
Business Society’s lithium carbonate data analyst believes that the current lithium carbonate market is mixed with negative and positive factors, and it is expected that the price will continue to fluctuate narrowly around the current price. Specific changes in market supply and demand still need to be monitored.
