The polyethylene market in May was mainly weak, with strong quotes for low-pressure products. After the May Day holiday, upstream enterprises and intermediaries accumulated inventory and faced significant inventory pressure, prompting businesses to actively reduce prices and ship goods; The demand for greenhouse film is low during the off-season, and the order volume is not good. Some enterprises mainly focus on phased production; The peak season for plastic film demand has ended, and except for a few areas with a small number of orders, large-scale areas have been in a state of shutdown for maintenance; The number of new orders in the packaging film market has decreased, and the intention to purchase for terminal essential needs has weakened; The demand side support is insufficient, and there are positive expectations from the macro perspective. On May 9th, international crude oil futures rose, but the cost side support was average. It is expected that polyethylene will operate weakly in a narrow range, with limited downward space.

According to the monitoring of the commodity market analysis system of Shengyi Society, the magnesium ingot market in Shaanxi Province rose this week (5.5-5.9), with an average market price of 16650 yuan/ton at the beginning of the week and 17275 yuan/ton over the weekend, an increase of 3.75%.
This week, the magnesium market was stirred up by developments related to the dolomite mine in Wutai County. Affected by the news from the mining area, downstream procurement demand has significantly released, with a significant increase in procurement volume. Factory inventory has quickly tightened, leading to a rapid rise in magnesium prices.
Supply and demand side
Some factories that were originally planned to gradually resume production after the holiday are currently adopting a wait-and-see attitude due to changes in the supply of dolomite; Enterprises that are still in production generally have lower inventory levels. Considering the possibility of further increase in raw material costs, these in production enterprises have a low willingness to ship and are more inclined to maintain price stability, resulting in a significant increase in their willingness to raise prices. There is currently no clear sign of a rebound in downstream demand.
Raw material end
Recently, the market price of coal used for producing blue charcoal has shown a downward trend, while the price of blue charcoal itself has remained relatively stable, and the price of ferrosilicon has also experienced a slight decline. However, due to the shortage of dolomite supply, companies have to seek alternative sources of goods from other regions. As a result, it is expected that the total production cost will increase significantly in the future.
comprehensive analysis
Once the shutdown period is extended, the smelting efficiency of the main magnesium production areas will be significantly suppressed, and the cost of raw material procurement will also increase significantly. In this situation, there is a possibility of further increase in magnesium prices.

According to the commodity analysis system of Shengyi Society, the market for hydrogen peroxide has slightly increased after the May Day holiday. On May 1st, the average market price of hydrogen peroxide was 693 yuan/ton. On May 7th, the average market price of hydrogen peroxide will be 700 yuan/ton, a decrease of 0.96% in price.
Demand increases, hydrogen peroxide market rebounds
After the May Day holiday, the demand for terminal printing and papermaking industries increased, and some hydrogen peroxide manufacturers continued to shut down for maintenance, resulting in a decrease in supply pressure. The price of hydrogen peroxide slightly increased, and the average price in the domestic market rose to around 700 yuan/ton, with a price increase of about 50 yuan/ton. The hydrogen peroxide market is heating up, with increased market transactions and mainly fluctuating upward trends.
Business Society’s hydrogen peroxide analyst believes that in mid May, the demand for terminal printing and papermaking industry will gradually increase, and the pressure on hydrogen peroxide supply will decrease. The market will continue to rise in the future.

According to the Commodity Market Analysis System of Shengyi Society, the coke market in Shanxi Province operated steadily on April 30th, with an average price of 1578.33 yuan/ton. Overall, the domestic coke market is currently operating in a narrow and weak range in April.
2、 Market analysis
In terms of price, the coke market in April showed a stalemate game feature. At the beginning of the month, enterprises raised prices, but were strongly resisted by steel mills and failed to land. Downstream steel mills’ profits contracted, demand was weak, and steel mills increased their pressure on raw material prices. The upstream cost support was insufficient, and downstream steel mills continued to be weak. On April 30th, the metallurgical coke prices in the Tianjin Port market were temporarily stable. The port’s quasi first grade coke prices are currently 1440 yuan/ton, and the first grade coke prices are 1540 yuan/ton, both of which are closing acceptance prices. On April 30th, the coke prices in the Binzhou market were temporarily stable. The local quasi first grade A13 dry quenching prices are 1570-1590 yuan/ton, and the second grade wet quenching prices are 1260 yuan/ton, both of which are factory prices including tax.
3、 Future forecast
Business Society’s coke analyst believes that the coke market is expected to experience weak fluctuations in the short term, and attention should be paid to the progress of steel mills’ profit recovery.

According to the Commodity Market Analysis System of Shengyi Society, the domestic natural rubber spot market has slightly declined since April. As of April 30th, the spot rubber market in China’s natural rubber market was around 14458 yuan/ton, a decrease of 10.60% from 16172 yuan/ton at the beginning of the month. In April, the downstream all steel tire production slightly decreased, while the half steel tire production remained stable, providing support for the demand for natural rubber; The natural rubber raw material market has fallen sharply, and the cost of natural rubber still supports a weakening trend; With the gradual transition of natural rubber supply from low production period to high production period both domestically and internationally, the domestic natural rubber inventory continues to increase slightly, which has a negative impact on the natural rubber market.
As of April 30th, the price of Thai glue was 58.50 baht/kg, a significant decrease from 68.00 baht/kg at the end of March, and a slight increase from the mid to low level. Currently, major overseas production areas are gradually being cut off, while Yunnan in China has already started cutting off. The expected supply of rubber raw materials at home and abroad is gradually increasing, and the price of natural rubber raw materials is expected to continue to decline in the later stage.
The natural rubber inventory continued to increase slightly in April, which had a bearish impact on the natural rubber market. As of April 27, 2025, the total inventory of Tianjiao bonded and general trade in Qingdao area was 608700 tons, slightly higher than the 602300 tons at the end of March.
The slight decrease in downstream tire production in April mainly supported the demand for natural rubber in the market. As of April 25th, the operating load of semi steel tires in domestic tire enterprises was around 7.8%; The production of all steel tires by tire companies in Shandong Province has slightly decreased to around 6.3% of the load.
Market forecast: Although there is a slight rebound in domestic and foreign raw material prices, expectations continue to decline in the later stage, and downstream inquiries are in a wait-and-see atmosphere, which weakens support for natural rubber. In addition, the inventory of Tianjiao Port is still at a high level; Overall, it is expected that the natural rubber market will continue its weak consolidation trend in the later stage.
