According to the monitoring of the commodity market analysis system of Shengyi Society, the magnesium ingot market in Shaanxi Province fell this week (10.27-10.31), with an average market price of 16375 yuan/ton at the beginning of the week and 16325 yuan/ton at the end of the week, a decrease of 0.31%.
The magnesium market shows a trend of first decreasing and then stabilizing, with a bottoming out and rebounding trend: In the early stage, the overall focus of magnesium prices continued to shift downwards. However, as the willingness of ordinary magnesium product production factories in Fugu area to further reduce prices gradually decreased, the market tended to operate stably in the later stage.
Supply and demand side
In terms of supply, the domestic economic situation has shown a stable and positive trend recently, with overall domestic demand remaining stable and rising, and market consumption vitality continuing to be released. However, due to fluctuations in the international market and some uncertain factors, export trading companies have adopted a cautious and wait-and-see attitude this week, with significantly reduced procurement plans for raw materials and commodities, waiting for further market clarity.
In terms of demand, this week, the supply of raw magnesium has remained stable compared to the previous period. At present, the inventory of magnesium smelting enterprises is still at a relatively low level, and the willingness of enterprises to raise prices is very strong. Most of them choose not to carry out shipment operations temporarily. However, as the end of the month approaches, some companies have experienced a small shipment due to cash pressure.
Raw material end
The price of coal shows a certain downward trend, while the price of blue charcoal remains generally stable, and the price of ferrosilicon has slightly decreased, resulting in a corresponding reduction in overall costs.
comprehensive analysis
This week, the market presents a fierce game between supply and demand, with strong willingness from upstream to raise prices, while downstream expectations for prices are relatively low. Due to the tight short-term cash flow of magnesium smelting enterprises, market prices have experienced a certain degree of decline. However, given the current situation of cost inversion, further price reduction faces significant difficulties.

The price trend of polyester bottle chips in October 2025 showed a trend of first suppressing, then stabilizing, and then increasing, but the overall fluctuation amplitude was relatively small. According to data from Shengyi Society, on October 30th, the average selling price of PET was 5785 yuan/ton.

price trend
In early October, the overall performance of the polyester bottle chip market was weak, and prices fluctuated downward. According to data from Shengyi Society, on October 10th, the market price in East China closed at 5812 yuan/ton, a decrease of about 40 yuan/ton compared to before the holiday. Subsequently, most polyester bottle chip companies lowered their prices by 20-50 yuan/ton.
Mid low stable: On October 14th, polyester bottle chip factories lowered their prices by 20-50 yuan, and on October 16th, some brands’ prices rose by 30 yuan due to the impact of raw materials. Overall, prices remained stable after fluctuating and falling in the middle of the month.
In the second half of the year, it first fell and then rose: According to data from Shengyi Society, on October 24th, the average selling price of PET was 5755 yuan/ton. At the beginning of the week, the price of polyester bottle chips fell due to the weakening of crude oil. Subsequently, geopolitical risks drove oil prices to rebound, cost support rebounded, and prices stopped falling and rebounded. On October 29th, the market experienced a slight correction, and on October 30th, the market rose narrowly again.
market analysis
Cost factor: In early October, international oil prices fell due to the easing of geopolitical tensions such as the ceasefire between Palestine and Israel, and the PTA market also showed weakness, resulting in the loss of important cost support for bottled tablets, which is the main pressure for price decline. In mid to late October, geopolitical risks once again pushed up oil prices, coupled with favorable policy releases: the Raw Materials Industry Department of the Ministry of Industry and Information Technology announced that it will hold a symposium on the development of the PTA and bottle grade polyester chip industry on October 29th. This move aims to prevent and resolve industry competition, greatly boosting market confidence and becoming an important force in promoting cost expectations and bottle chip price rebound
Supply and demand relationship: In terms of supply, the industry’s capacity utilization rate remained around 72.59% this week, and mainstream factories continued to implement production reduction plans. However, the market’s spot supply is still abundant, and overcapacity is a long-term pressure faced by the industry, which has suppressed price increases. In terms of demand, currently in the off-season of seasonal demand, the cooling weather has led to a narrow decline in demand for soft drinks and catering. Downstream end users mostly adopt the strategy of “on-demand procurement” and lack enthusiasm for large-scale stocking.
Export situation: According to customs statistics, the total export volume of polyester bottle flakes from January to September 2025 reached 4.81 million tons, a year-on-year increase of 14%. Among them, the export volume in September was 468000 tons, a year-on-year increase of 7% but a month on month decrease of 10%. Affected by upstream raw materials, the export quotation of polyester bottle chip factories has been raised, and the negotiation range for mainstream bottle chip factories in East China has been extended to $750-770/ton FOB Shanghai Port.

Business Society believes that the future market will be warm and volatile. The cost side is expected to strengthen under the support of geographical factors, which will provide cost support for bottle flakes. However, due to stable supply and abundant spot goods, as well as seasonal off-season demand, the upward space for bottle flake prices is limited, and it is expected to fluctuate within the range of 5600-5800 yuan/ton.

According to the Commodity Market Analysis System of Shengyi Society, the domestic aggregated MDI market experienced a weak decline in October. From October 1st to 29th, the domestic market price of aggregated MDI increased from 14833 yuan/ton to 14300 yuan/ton, with a price drop of 3.6% during the month and a year-on-year price drop of 21.79%.
In early October, mainstream manufacturers lowered prices and traders frequently offered low prices. The messaging platform is relatively quiet, with insufficient support and low downstream demand, mainly consisting of small transactions. The mentality of the industry is relatively pessimistic, and prices continue to decline.
In mid to late October, mainstream manufacturers continued to lower prices, and traders’ quotes followed the market trend. Subsequently, the maintenance plan of major factories was announced, and the prices of traders tentatively increased, leading to an increase in inquiries and a slight improvement in the trading atmosphere. The aggregated MDI market continued to weaken after a slight increase, and the market remained stagnant until the end of the month.
Supply side: Jinhu, South Korea’s 200000 tons/year MDI will undergo maintenance in early September, with a duration of 20-30 days. Wanhua Ningbo has a maintenance plan in November, and the rest of the equipment is running smoothly.
On the cost side, pure benzene raw material: downstream of pure benzene continues to suffer losses, with low enthusiasm for raw material procurement and cautious market sentiment. Combined with weak downstream growth and insufficient new orders from end-users, the pure benzene market continued to decline in October. The aniline market remained strong and rose in October. On October 1st, the market price of aniline was 7750 yuan/ton, and on October 28th, the price was 7995 yuan/ton, with a 3.06% increase during the period.
On the demand side, the downstream peak season is not prosperous, and the silver ten market has ended flat. With strong supply and weak demand, the aggregated MDI market is prone to decline but difficult to rise.
Market forecast: Major factories have maintenance plans in November, and the current market is reluctant to sell at low prices. The supply side is supported, but the demand side is unlikely to improve. It is expected that the aggregated MDI market will fluctuate within a certain range in the short term.

price trend
According to the bulk ranking data from Shengyi Society, the domestic PC market entered a volatile consolidation trend at the end of October. The spot prices of some brands have fluctuated. As of October 28th, the mixed benchmark price of Business Society PC is around 14283.33 yuan/ton, with a price increase or decrease of -1.27% compared to early October.
Root cause analysis
On the supply side: In the first half of October, the load of domestic PC aggregation enterprises remained stable with small fluctuations. As the end of the month approached, the industry’s operating rate decreased by 4% to 77%, and the weekly average output was about 65000 tons, a slight decrease from the beginning of the month. In terms of inventory, it remains strong, but the improvement in the pattern of abundant PC supply is limited. The market is waiting for many aggregation plants to undergo maintenance and release positive news from the supply side. Overall, there is a strong expected trend in the PC supply side, which strengthens support for PC.
In terms of raw materials, it can be seen from the above chart that the bisphenol A market significantly declined in October. Upstream phenol fell and then consolidated, while acetone fell sharply and entered a recovery market, which is difficult to say for the bisphenol A market. In addition, the continuous weakness of bisphenol A consumption has led to a rapid decline in spot prices due to multiple factors. Although the current market atmosphere remains weak, spot prices have fallen to low levels, coupled with controllable inventory and increased price manipulation by enterprises and businesses, forming a trend of bottoming out. It is expected that the price of bisphenol A will remain stable in the future, while the support for PC costs will remain weak.
On the demand side: October is still in the traditional peak season for PC, but the downstream factory load of the “Golden Ten” this year is not ideal, inventory digestion is slow, and stocking remains at a weak level of rigid demand. Although maintenance signals have stimulated some brands to rise, the improvement in market trading activity is limited. At the same time, external news indicates that the export market is volatile, and the overseas shipment of PC terminal products is under pressure and weakening. In the second half of the month, merchants tend to focus on selling goods to recoup funds, resulting in a concentration of profit taking orders and a stagnation and decline in the price center. Buyers are resistant to high priced goods, and once the demand for filling gaps is met, the circulation speed of market goods slows down again. Overall, the demand side lacks support for PC spot prices.
Future forecast
At the end of October, the domestic PC market in China fluctuated and consolidated. The upstream bisphenol A market has stopped falling at a low level, and the cost value has not shown any improvement in supporting PC. The load of domestic PC aggregation plants has been reduced, the market trading situation is poor, and there is a supply-demand game in the market. It is expected that the PC market will continue to consolidate in the short term.
