2、 Market analysis
Supply and demand situation
The price of ammonium sulfate in the domestic market has slightly decreased this week. The operating rate of coke enterprises remains stable, while the operating rate of domestic enterprises has decreased. At present, the ammonium sulfate market has sufficient supply and weak demand. Downstream demand for replenishment is increasing, with more low-priced purchases and reduced purchasing enthusiasm. The trading atmosphere in the ammonium sulfate market is light and there are currently no favorable factors.
market situation
As of August 22nd, the mainstream ex factory quotation for coking grade ammonium sulfate in Shandong region is around 1000 yuan/ton. Domestic grade ammonium sulfate, the mainstream ex factory quotation in Shandong region is around 1030-1090 yuan/ton.
3、 Future forecast
An ammonium sulfate analyst from Shengyi Society believes that the market trend of ammonium sulfate has been weak and downward recently. At present, the trading atmosphere in the ammonium sulfate market is not good, and downstream purchasing sentiment is not high. There is currently no positive news for exports. It is expected that in the short term, the domestic ammonium sulfate market price will be weak and mainly operated through consolidation.

According to the Commodity Market Analysis System of Shengyi Society, the price of domestic polyester staple fiber fluctuated upward this week (August 18-22). As of August 22, the average market price of domestic polyester staple fiber (1.4D * 38mm) was 6562 yuan/ton, up 1.4% from the beginning of the week.
Costs are gradually rising, and the domestic PTA market has slightly rebounded this week. The average price of PTA in the East China region is 4771 yuan/ton, up 1.08% from the beginning of the week. The overall fundamentals of PTA have improved, and the overseas market supply of PX on the cost side is slightly tight. The expected production of new PTA facilities at home and abroad has strengthened demand support, and PX is gradually strengthening. PTA East and South China facilities have postponed restart and shutdown due to unforeseen circumstances, optimizing their own supply structure. Downstream polyester demand is stable and there is a high volume of production and sales. Combined with the recent macro driven improvement in commodity sentiment, the PTA market price has risen slightly.
Downstream yarn factories are showing increasing resistance and maintaining a focus on replenishing essential goods. Since August, with the easing of tariffs, the orders for autumn and winter fabrics and foreign trade home textiles have gradually increased, and the operating rate of the mainstream weaving industry in Jiangsu and Zhejiang is around 52%. However, the inventory of regular greige fabrics from intermediaries and factories is still at a high level, coupled with limited overall follow-up of new orders, the space for further load increase is limited. Moreover, the actual issuance of large orders remains weak, and in this context, yarn factories prioritize the recovery of funds, making it difficult to see a significant increase in actual demand.
Business analysts believe that PTA is in a phase of improvement in supply and demand, with increased cost support, and the traditional peak demand season for September is approaching. They also have expectations for September demand. Among them, the essential orders for home clothing and bedding fabrics in early winter have been gradually released, while the autumn clothing orders have entered a concentrated delivery period, which will jointly promote the sustained recovery of the overall market atmosphere. It is expected that the short-term prices of polyester staple fibers will continue to be strong.

According to the Commodity Market Analysis System of Shengyi Society, the price of acetic acid has slightly increased recently. On the 19th, the average market price of acetic acid was 2400 yuan/ton, an increase of 30 yuan/ton or 1.27% from the price of 2370 yuan/ton on August 11th. Since mid August, the domestic acetic acid market has mainly operated weakly, mainly due to the high utilization rate of on-site production capacity and the maintenance of high market supply. However, the downstream market is weak, and the enthusiasm for entering the market for purchasing is not high. The demand side support is limited, and the market supply-demand contradiction is deadlocked, with prices in most areas maintaining low levels; On the 19th, the supplier announced that the equipment of manufacturers in Central China has been shut down, and the factory prices have increased significantly. Market prices in other regions have also kept up with the increase.

As of the 19th, the average price in the domestic market was 2301.67 yuan/ton, a decrease of 3.39% compared to the price of 2382.50 yuan/ton on August 11th. During the cycle, the social inventory of ports continues to accumulate, and the mentality of operators is bearish. The demand for spot methanol market is weak, downstream acceptance of high prices is not smooth, the market trading atmosphere is poor, and the focus of the methanol market continues to decline.
The downstream acetic anhydride market has slightly decreased, with the average ex factory price of acetic anhydride dropping from 4092.50 yuan/ton to 4082.50 yuan/ton from August 11th to 19th, a decrease of 0.24%. The trading atmosphere in the upstream acetic acid market is weak, with insufficient support for acetic anhydride. Downstream buyers follow up on demand, and the market trading atmosphere is weak. The supply and demand in the acetic anhydride market are deadlocked, and the price of acetic anhydride fluctuates slightly during the cycle.
Market forecast: Business Society’s acetic acid analyst believes that the utilization rate of domestic acetic acid production capacity remains high, and the market inventory is sufficient. Although the supply news has boosted the mentality of industry players, downstream demand is poor, and enterprise shipments are limited. The situation of oversupply in the market still exists in the short term. It is expected that the acetic acid market will weaken and consolidate in the later stage, and downstream follow-up will be closely monitored in the future.

According to the monitoring of the commodity market analysis system of Shengyi Society, the magnesium ingot market in Shaanxi Province made slight adjustments this week (8.11-8.15), with an average market price of 17450 yuan/ton at the beginning of the week and 17437 yuan/ton at the end of the week, a decrease of 0.07%.
This week, the magnesium market showed a trend of first being strong and then weak, with overall stability and narrow fluctuations. At the beginning of the week, the market operation was relatively strong, but later, due to the slowdown in demand follow-up speed, the market turned to weak and stable operation. Some factories lowered their prices slightly to win orders, while those factories that were not in a hurry to ship temporarily maintained stable quotations.
Supply and demand side
On the supply side, magnesium smelting enterprises are in a state of supply shortage, so most of these enterprises have a strong willingness to maintain high prices. However, due to cash demand in the middle of the month, some companies chose to lower prices slightly to promote shipments.
On the demand side, downstream customers have a high acceptance of the price of 17400 yuan per ton, but when faced with a price of 17500 yuan per ton, most of them adopt a wait-and-see attitude. Overall demand remains stable, but trading volume has declined towards the weekend.
Raw material end
Recent market trends have shown that coal prices continue to rise, driven by the dual effects of tightening supply and sustained recovery in demand, resulting in a continuous increase in coal prices in major production areas. Driven by this, the price of blue charcoal, a downstream product of coal, has also shown a rising trend, and the performance of the silicon iron market is relatively stable.
comprehensive analysis
The magnesium market has once again entered a stage of consolidation, and the current situation between supply and demand is basically balanced. Magnesium prices are expected to remain relatively stable next week.
