Recently, the international crude oil geopolitical risk aversion sentiment has subsided, oil prices have fluctuated and fallen, and the center of gravity of raw material costs has shifted downwards, dragging down the polyethylene market.
The maintenance benefits are gradually diminishing, and the circulation of goods is loose. Multiple sets of polyethylene plants will resume production in mid June. The recovery of shipping in the Middle East, the increase in the arrival volume of imported LDPE at ports, and the surplus of high-pressure material sources are the core reasons for the deepest decline in LDPE. Yangtze Petrochemical has been shut down for long-term maintenance, and there is a temporary shortage of low-pressure materials in the East China region, with some spot stocks resisting the decline.
Off season for agricultural film: The demand for plastic film and greenhouse film has all come to an end, and the production of agricultural film has fallen to a low level this year. The production of packaging film, injection molding, hollowing, and coating has declined, resulting in a backlog of finished product inventory. Downstream factories are all purchasing on demand without any advance replenishment behavior. Traders actively reduce prices and sell off inventory, exacerbating the price decline.
Continued loose supply coupled with downstream off-season drag has led to overall weak volatility of polyethylene in the short term. After a sharp decline, there may be a slight narrow recovery, but the rebound space is limited.

1、 Price trend
On June 6th, the average market price of 55% powdered ammonium in Hubei region was 4280 yuan/ton, and on June 12th, the average market price of 55% powdered ammonium in Hubei region was 4383 yuan/ton. This week, the market price of ammonium phosphate increased by 2.41%.
2、 Market analysis
This week, the market price of ammonium phosphate has been strong and rising. The price of raw material sulfur has significantly increased, and under cost pressure, the market price of ammonium phosphate has risen steadily. Manufacturers still mainly execute early-stage orders, while downstream purchases are made on demand, resulting in an improved market transaction atmosphere. As of June 12th, the market price of 55 powder ammonium in Hubei region is around 4350-4450 yuan/ton, in Henan region it is around 4450-4500 yuan/ton, and in Sichuan region it is around 4200 yuan/ton.
In terms of raw material sulfur. Due to the tense situation in the Middle East, sulfur prices have once again risen strongly this week, exceeding 10000 yuan. At present, the port inventory continues to decline, and there is a large gap between market supply and demand. It is expected that sulfur prices will remain high in the short term.
3、 Future forecast
An analyst from Shengyi Society believes that the market trend of ammonium phosphate has been dominant in recent days. Due to cost support and tight market supply, it is expected that the short-term market for ammonium phosphate will continue to operate with a strong upward trend. Suggest paying attention to changes in the raw material market.

From June 3rd to June 12th, the 1 # tin ingot market in East China fell, with an initial market average price of 447020 yuan/ton. As of June 12th, the market average price was 410940 yuan/ton, a decrease of 8.07%.
Since June, the main contract of Shanghai tin has repeatedly turned back in the range of 390000 to 440000 yuan/ton. The price fluctuated within a wide range this week, with extremely fast direction switching and broad fluctuations being the core color of June.
Supply side
The resumption of tin mining in the Wa State of Myanmar has significantly fallen short of expectations. As of now, due to multiple factors such as operational restrictions, material approvals, and the arrival of the rainy season, the production capacity of the Manchurian tin mine has only been restored to 40% to 50% of its pre mining capacity; The rainy season from May to July further suppresses open-pit mining and transportation, resulting in limited incremental space in the short term. In April, China imported 5678 physical tons of tin ore from Myanmar, a decrease of 22% compared to the previous month, which was only about 36% of the monthly average level before the shutdown. On the Democratic Republic of Congo side, about 6% of tin exports from Bisie mine are obstructed. Indonesia’s refined tin exports in April decreased by over 50% compared to the previous month, and the increase in mineral tax rates to 20% has pushed up long-term costs. Multiple tightening measures on the supply side have established a rigid bottom support for tin prices.
demand side
AI computing power hardware drives tin demand growth, accounting for about 10%, with high price tolerance and clear long-term support. In terms of traditional demand, lead-acid batteries have entered the off-season, production and sales of photovoltaics and new energy vehicles have slowed down, exports of tinplate have significantly declined, and the recovery of consumer electronics is moderate. High priced tin suppresses spot purchases of solder materials, while downstream rigid purchases dominate and there is a weak willingness to replenish inventory. The demand for tin supports the bottom but does not chase up prices, putting upward pressure on tin prices.
comprehensive analysis
As of now, the tin price has gone through an extreme trend of “hitting the top, trampling, and rebounding”. In the short term, it has entered a tug of war between the suppression of the moving average and the bottoming out of demand, with volatility still the main theme; In the medium to long term, tight fundamentals and AI demand still support the upward shift of the price center, but in the short term, inventory and macro pressures need to be digested.

As of June 11th, the price of 0 # zinc was 24152 yuan/ton, a decrease of 2.25% from the zinc price of 24708 yuan/ton on June 1st.
fundamentals
At the macro level, multiple factors resonate to suppress emotions in the non-ferrous metal sector. The overall stance of the Federal Reserve’s June interest rate meeting is hawkish, coupled with the US May non farm payroll data exceeding expectations, the market is once again facing a combination of “strong employment+rising inflation”, and financial attribute pressure continues. The escalation of the situation in the Middle East has raised concerns about inflation and the risk of economic slowdown, with London zinc prices falling by about 1%, indicating a significant decline in market risk appetite.
Supply side: The current most solid support logic
The processing fee (TC) for zinc concentrate remains at a historically low level, and the pricing of domestic ore in June further declined compared to the previous month. The extremely scarce situation in the mining sector has seriously damaged the profits of smelting enterprises, with processing fees continuously bottoming out and by-product sulfuric acid prices falling. Most smelting plants have already fallen into substantial losses. The passive production reduction forced by this is being realized: the expected increase in centralized maintenance at the domestic smelting end in June has led to a tight output of refined zinc. In addition, LME zinc inventory continues to deplete, providing bottom support for prices.
Demand side: The current biggest suppression factor
With the arrival of the southern rainy season, terminal demand is gradually shifting into the traditional off-season. The operating rate of galvanizing enterprises has decreased, and the operating rate of die-casting zinc alloys has also declined, both at a historically low level. Downstream enterprises generally have a bearish outlook on the future market, maintaining the price of essential needs for procurement and a low willingness to replenish inventory. The terminal consumption sector also lacks highlights: the marginal driving force for the rebound in infrastructure investment growth rate is limited, while the production of automobiles and household appliances has negative growth, the real estate industry remains weak, coupled with a decrease in external demand risk appetite, and overall demand support is insufficient.
comprehensive analysis
The short-term trend has shifted towards weakness, with the market showing a downward trend after high-level fluctuations, but the downward space is constrained by the rigid support of mining shortages and smelting losses. The current market is in a game stage of macro bearish release and fundamental bottom support, and paying attention to 24000 yuan/ton is an important long short watershed. In the medium to long term, in mid to late June, it is important to focus on the substantial realization of the reduction in maintenance and production at the smelting end, as well as whether domestic inventory can continue to decline. These two factors will be the core catalysts for the stabilization and recovery of zinc prices.

Isooctanol prices fluctuate and rise in June
On June 8th, the price of isooctanol was 8133.33 yuan/ton, a fluctuating increase of 2.09% compared to 7966.67 yuan/ton at the beginning of the month. Since June, several leading enterprises in Shandong have frequently raised their quotations, showing a clear willingness to raise prices and driving the market focus slightly upward. The isooctanol market is experiencing a mild upward trend.
Market forecast:
In June, the isooctanol price moving average rose above the 10 day price moving average and the 20 day price moving average. On June 7th, the 10th price moving average crossed the 20th price moving average, and the upward signal of isooctanol was strengthened, showing an upward trend.
From a one-year perspective, the current price of 8100 yuan/ton is in the historical high range, significantly higher than the low volatility zone from June to the end of 2025, and also higher than the annual average price of 7249.70 yuan/ton in 2025. On June 8th, the price was at a 20 day high and a 30 day low. The price of isooctanol is relatively high, and the driving force for a significant increase is limited.
Weakened support for high propylene costs
On June 8th, the propylene price was 8824.33 yuan/ton, a decrease of 2.36% from the propylene price of 9037.67 yuan/ton on June 1st. The propylene market is currently in a bottoming out stage, and strong macro guidance provides a safety cushion for the market. The price of propylene is maintaining a stable pattern, and the market lacks upward momentum, resulting in continued cost pressure and downward pressure on isooctanol.
Adequate supply of isooctanol
It is expected to increase production capacity by approximately 1.14 million tons per year in 2026, with a total supply of 3.73 million tons. In May, the operating load of isooctanol enterprises decreased, resulting in a reduction in isooctanol supply and increased support for the rise in isooctanol prices.
Outlook for the future market
According to the data analyst of Business Society’s octanol product, the isooctanol market rebounded in June, but overall, the market still faces significant “high-level pressure” throughout the year. There is significant overcapacity in the industry, and with the concentrated release of new production capacity in June, inventory pressure may rapidly increase, becoming a key factor restricting future price upward space. The expected future price of isooctanol is expected to fluctuate and consolidate widely.
