According to the Commodity Market Analysis System of Shengyi Society, as of the 30th, the price of ethyl acetate was 5456.67 yuan/ton, an increase of 0.43% compared to the price of 5433.33 yuan/ton on May 25th, and a decrease of 1.09% compared to the beginning of the month. The upstream market is experiencing strong fluctuations, while the downstream is following up on demand. Market transactions are still acceptable, and ethyl acetate companies are actively shipping, with a strong upward trend in price focus.
This week, the utilization rate of domestic ethyl acetate production capacity has decreased, and the market supply pressure has weakened. At the beginning of the week, raw materials rose and the supplier’s mentality was optimistic. Ethyl acetate enterprises followed suit and increased their prices. Downstream demand mainly entered the market according to demand, and there were many low-priced inquiries in the market. Some enterprises had smooth transactions, and the price of ethyl acetate remained firm. The partial price reduction of upstream acetic acid in the later part of the week has a negative impact on the market of ethyl acetate.
Looking at the future market, the ethyl acetate market is running steadily, with manufacturers having a strong mentality and downstream following up on demand. Enterprise sales are still acceptable, but the decline in raw material prices has weakened market support. It is expected that the price of ethyl acetate may be slightly lower in the later stage, and specific attention should be paid to changes in supplier equipment and downstream follow-up.

According to the Commodity Market Analysis System of Shengyi Society, the domestic PP market in May was consolidating and operating, with some brand products experiencing narrow price reductions. As of May 31st, the mainstream offer price for wire drawing by domestic producers and traders is around 7393.33 yuan/ton, a decrease of -1.18% compared to the price level at the beginning of May.
price trend
In terms of raw materials:
From April to early May, the US tariff policy was implemented, with tariff rates constantly changing and increasing to unprecedented heights. The tariff trade war launched by Trump has had a huge impact on the global economy. Crude oil, as a heavily affected area, has experienced a sharp drop in prices. With the release of many positive signals such as the suspension of tariffs during the mid May China US talks, crude oil prices have continued to rebound. In addition, the tense geopolitical situation in the Middle East and Eastern Europe has increased the risk of crude oil supply, and prices have remained firm. At the same time, the decoupling of domestic propane trade is expected to gradually be lifted, and the cost pressure on PDH manufacturing enterprises may decrease in the future, but the differentiation of demand will hinder the growth rate. There is a certain degree of loose supply in the propylene sector, coupled with average digestion speed, resulting in price fluctuations and downward adjustments. Overall, the prices of PP raw materials fluctuated in May, with mixed ups and downs, providing moderate support for PP costs.
Supply side:
In May, the load of domestic PP enterprises remained stable with small fluctuations, rising and then falling back, and the market supply remained generally abundant. Overall, the current industry’s overall load level has increased by 1% to around 77% compared to the end of April, and the weekly average total output of about 750000 tons has also remained flat. The capacity loss caused by the maintenance plan of interval enterprises has been basically smoothed out by the restart of enterprises such as Lanzhou Petrochemical. At the same time, the new production capacity of 1.4 million tons in the next quarter is approaching, and there is a clear expectation of loose supply in the future. The total domestic inventory has narrowly decreased to below 820000 tons, but remains at a high level. Overall, there is still some suppression on the spot price of PP by the supply side.
In terms of demand:
In May, the demand for PP continued to be weak, and on-site trading gradually entered the traditional off-season. The goods were basically ready before the Dragon Boat Festival, and the market remained weak and rigid. The consumption level of plastic weaving terminal enterprises has returned to the off-season level ahead of schedule. With the passing of the small peak in material usage, the release speed of PP demand in fields such as construction and agriculture has slowed down. The news of the temporary suspension of tariffs between China and the United States in the early stage stimulated market sentiment, and consumption briefly increased. At the end of the month, the impact has cooled down, and although the export resistance of downstream PP products in China has decreased, the incremental delivery of export orders still needs time. At the same time, there is still supply pressure in the industry, and inventory still needs to be cleared, offsetting some positive factors. The current buyers are cautious in their purchasing operations to maintain production, leaning towards scattered small orders, and the market’s new order transactions are returning to a flat state. Overall, the performance of PP demand side in May was average.
Future forecast
In May, the domestic PP market price consolidation was weak. From a fundamental perspective, fluctuations in upstream raw material prices have provided average overall support for PP. The industry has abundant supply, inventory continues to be digested, and consumption has entered the off-season level. At present, the positive sentiment of macroeconomic policies is being digested, and the market is returning to supply-demand dominance. It is expected that the PP market will continue to consolidate in early June, and it is recommended to closely monitor the new production situation in the industry.

According to the monitoring of the commodity market analysis system of Shengyi Society, the magnesium ingot market in Shaanxi Province fell this week (5.26-5.30), with an average market price of 17050 yuan/ton at the beginning of the week and 16900 yuan/ton at the end of the week, a decrease of 0.88%.

Last week, the magnesium market showed a narrow fluctuation adjustment trend. Entering the first half of this week, due to the lack of significant improvement in market demand and the financial pressure faced by some factories towards the end of the month, these factories have chosen to offer slight price reductions and promotions in order to win orders. At the same time, some factories have maintained stable quotes or temporarily chosen not to quote, resulting in the overall magnesium market continuing its weak and stable consolidation pattern.
Supply and demand side
Recently, the downstream market is still dominated by essential procurement, and some factories have flexibly adjusted their sales strategies based on market conditions and actively shipped goods. For factories without inventory pressure, the willingness to continue lowering prices and shipping is not strong. Currently, spot resources are relatively limited, and factories are generally unwilling to ship at low prices. Affected by external factors such as the uncertainty of US tariff policies and the slowdown in global economic growth, downstream buyers are currently generally cautious. In this context, it is difficult to achieve a significant improvement in the magnesium market in the short term. Given the limited stock reserves of factories, the magnesium market price may remain at the current level, showing a stable and narrow consolidation trend. Market participants are seeking new supply and demand balance points.
comprehensive analysis
In the current situation where overall demand is weak and there is no significant positive news to stimulate the market, it is expected that the magnesium market will still face many challenges in the short term, and the market will continue to be under pressure; However, considering that the current factory spot inventory is generally low, coupled with the continued existence of essential procurement, this will provide some support for the magnesium market price, and it is expected that the difficulty of further decline in the magnesium market will increase. On the whole, the magnesium market may maintain a weak and stable trend before the Dragon Boat Festival, and all parties in the market will pay close attention to the follow-up demand.

Aluminum prices rebound in May
Aluminum prices rebounded in May. According to the Commodity Market Analysis System of Shengyi Society, as of May 29, 2025, the average price of aluminum ingots in the East China market in China was 20396.67 yuan/ton, an increase of 1.61% from the market average price of 20073.33 yuan/ton on May 1.
Factors influencing the aluminum price trend in June
Supply side: The operating capacity of electrolytic aluminum in June is expected to increase by about 200000 tons, and the effective operating capacity is expected to climb to over 44 million tons, with a slight increase in production. In terms of overseas imports, the import volume is expected to remain relatively high, and the overall supply is showing an increasing trend, which will put some pressure on aluminum prices.
On the demand side: June is the off-season for traditional consumption, and the demand for traditional end markets such as building profiles and home appliances may be weak. However, the new energy vehicle market maintains high-speed growth, which will continue to drive aluminum demand. However, the photovoltaic market may experience a significant decline in production after the rush to install is over. In terms of exports, there is a 90 day export window period after the adjustment of tariffs between China and the United States, and there is still a rush to export before the end of the window period, which provides some support for aluminum prices.
On the cost side: The spot price of alumina lacks momentum for further increase, and there is even a possibility of a downward trend. The cost center of electrolytic aluminum is expected to decrease, weakening its support for aluminum prices. The price of pre baked anodes for auxiliary materials may continue to decline in June.

Macroscopic factors: there is still uncertainty in international trade relations, the issue of US treasury bond debt has caused concern, domestic macro policies are waiting to be implemented, and macro disturbances make market sentiment more cautious
June aluminum price trend forecast
Overall, it is predicted that aluminum prices will show a weak and volatile trend in June 2025.

According to the Commodity Market Analysis System of Shengyi Society, the domestic PTA spot market in May showed a trend of first rising and then falling. As of May 27th, the average price of PTA in the East China region was 4938 yuan/ton, an increase of 7.73% from the beginning of the month.
Looking at the future market, PTA units will undergo centralized maintenance in May, and gradually restart in the latter half of the year. As of the end of the month, the PTA industry’s operating rate is around 78%. After the repair of the disk processing fee, the implementation of device maintenance in June and July may not meet expectations. New production capacity such as Honggang Petrochemical Phase III and Hailun Petrochemical Phase III will be put into operation from June to August, with a focus on loose supply in the long term.
The current settlement price of the main WTI crude oil futures contract in the US crude oil market is $60.89 per barrel, and the settlement price of the August Brent crude oil futures contract is $63.57 per barrel. Trump has postponed imposing tariffs on the European Union, but OPEC and its allies are considering another significant increase in production, so the oil market is weighing the short-term prospects of easing trade tensions and increasing OPEC+supply.
Recently, with the restoration of PX benefits, some domestic and foreign facilities have increased their capacity, and early-stage maintenance facilities have gradually restarted. For example, the 1.6 million ton facilities of Zhongjin Petrochemical and the 4 million ton facilities of Zhejiang Petrochemical have been restarted in advance, resulting in a gradual increase in PX supply. The gradual reduction in downstream polyester production, weakened supply and demand margins, and limited support for crude oil prices have put significant upward pressure on PX. However, as the downstream PTA load gradually increases, the short-term supply and demand of PX are good, and the current spot market supply is tight, PX is still relatively resistant to decline.
Under the sharp rise in raw material prices, downstream polyester products have expanded their losses, and the main focus is on digesting raw material inventory after low-level stocking at the end. In addition, with the expectation of China’s export rush to the United States gradually coming to an end in late June and the arrival of the off-season for domestic sales, terminal textile enterprises are cautious and cautious, with rigid demand procurement as the main focus, resulting in light trading in the polyester market. The high inventory pressure brought about by nearly 90% of high production will increase, and some polyester factories have begun to implement production cuts. It is expected that there will be a greater certainty of production cuts in the third quarter.
Overall, analysts from Shengyi Society believe that crude oil prices are dominated by geopolitical risks and policy games, and unexpected events may drive up oil price volatility. The increase in supply brought about by downstream polyester production reduction and the introduction of new PTA production capacity will suppress the upward space of PTA prices, and it is expected that the PTA market will be under pressure in June.
