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.

From June 1st to 5th, the domestic BDO price dropped from 8100 yuan/ton to 8303 yuan/ton, with a price drop of 0.21% during the period, a month on month drop of 4.95%, and a year-on-year drop of 1.25%. The supply and demand pressure in the domestic BDO market still exists, and the poor terminal demand has led to a continuous decline in downstream industry prices and increased cost pressure. Business owners have a bearish attitude towards purchasing and sales, and are negotiating to offer discounts on actual orders, resulting in a volatile downward market trend.
In terms of supply and equipment, there are frequent fluctuations in the equipment sector, leading to a decline in industry capacity utilization and an increase in supply side support. And the online auction transaction reached a high of 7950 yuan/ton, enhancing the supplier’s market stability mentality. The positive impact of BDO supply has weakened.
In terms of cost and calcium carbide, the domestic price of calcium carbide has decreased, and some production enterprises have accumulated inventory. In order to accelerate shipments, some enterprises are flexible in their shipments. In terms of methanol, the price of methanol continues to rise, and inland factories are concentrated in pre-sales and exceeding orders, which has hindered the transportation and loading of vehicles in many places. The downward trend in the raw material calcium carbide market and the upward trend in the methanol market have had a mixed impact on BDO costs.
On the demand side and downstream side, there is no significant improvement in downstream demand at the terminal. In the situation of supply-demand contradiction and poor cost transmission, downstream industries offer discounts and promotions, leading to a decline in market conditions in most industries. The demand side of BDO is affected by bearish factors.
Future forecast: raw material calcium carbide will decline, methanol will fluctuate within a certain range, and BDO cost pressure will weaken. The downstream PBT and PBAT industries will experience a decline in load and a reduction in demand in the next period. Overall, BDO analysts from Shengyi Society predict that the domestic BDO market will operate weakly.

From May 31st to June 2nd, the 1 # tin ingot market in East China rose, with an initial market average price of 424960 yuan/ton. As of June 2nd, the market average price was 442580 yuan/ton, an increase of 4.15%.
Entering June, tin prices continued their strong performance since the beginning of the year, and market attention increased significantly. On June 2nd, the main contract of Shanghai tin closed up more than 5%, reaching a high of 449960 yuan/ton, maintaining a high level of operation. The non-ferrous sector led the way in the tin direction, with multiple stocks hitting the daily limit up or significantly following suit. From the cumulative increase since the beginning of the year, Shanghai Tin has risen by about 33% this year, and LME Tin has risen by nearly 40%, with market trading sentiment continuing to heat up.
The following analysis from the supply and demand side: the bidirectional resonance between “rigid contraction of supply” and “structural explosion of AI computing power demand”
supply side
The three major producing countries are simultaneously facing supply reduction difficulties: Myanmar’s Manxiang mining area is constrained by factors such as civil explosive factory accidents and material approvals, with production capacity only restored to 40% to 50% of pre mining levels. In addition, the rainy season from May to July further restricts open-pit mining and transportation, making it difficult to see short-term growth; On the Indonesian side, the update of export licenses coupled with the government’s crackdown on illegal smelting resulted in a nearly halving of refined tin exports in April, and a further 32% year-on-year decrease in exports in May. At the same time, the highest royalty rate doubled from 10% to 20%, comprehensively raising the production cost of tin ore; In the Democratic Republic of Congo, the export of Bisie tin ore has been hindered due to the closure of the Goma port, coupled with geopolitical and public health disturbances, leading to uncertainty in approximately 6% of the global tin ore supply. Under the triple disturbance superposition, the tight logic of the raw material end continues to strengthen, and the cost transmission from the mining end to the smelting end continues to advance.
demand side
Tin, as a ‘computing power metal’, presents distinct differentiation: tin usage in high margin tracks such as AI servers and optical modules has surged and is not afraid of price increases, while traditional consumer electronics are cost sensitive and procurement is in a wait-and-see state. This kind of ice and fire game is forcing midstream and downstream enterprises to transform towards high-end. At the same time, global tin mines can only be mined for 15 years (12 years in China), but tin can be recovered and regenerated without damage. Top enterprises are laying out a “mining recycling regeneration” closed-loop, and recycling tin has become a strategic direction to overcome resource bottlenecks. What is even rarer than computing power itself is the underlying resources that support computing power – whoever can afford high priced tin will dominate the future of the industry chain.
comprehensive analysis
In the short term, upstream supply disturbances will continue to be the dominant force in tin prices, supporting the continued strong operation of tin prices. On the other hand, downstream electronic solder has entered the traditional consumption off-season, and some terminals are adopting a wait-and-see attitude towards high prices, with spot transactions tending to be cautious. The short-term tin price is likely to maintain a high and wide range oscillation pattern. In the medium to long term, the supply-demand gap will continue to provide solid upward support for the tin price center.

In May, the domestic ABS market continued to fluctuate and fall, with most spot prices of various grades decreasing. According to data from Shengyishe Spot News, as of May 31st, the average price of ABS sample products was 9900 yuan/ton, a decrease of 11.45% from the beginning of the month.
Fundamental analysis
Supply level: In May, the domestic ABS industry saw a combination of equipment maintenance and resumption of work. The overall operating level of the industry fluctuated at a low level throughout the month, remaining at around 59% at the end of the month. The current weekly average production is less than 130000 tons, and the inventory of finished products is around 200000 tons. The shipment situation of aggregation plants gradually declined within the month, and there is still a slight increase in production expected in the short term in the future. Overall, the ABS supply side’s support for spot prices in May is still acceptable.
Cost factor: Since May, there have been frequent reports of preliminary peace agreements between the United States and Iran in the Middle East, with high-level officials from both sides releasing positive signals. Although it will take some time for shipping to resume in the Strait of Hormuz, the market predicts that the Middle East conflict is likely to ease, and the geopolitical stalemate between the United States and Iran has led to significant fluctuations in risk premiums. Oil prices surged in the middle of the month and then plummeted again in the second half. Affected by it, the cost value of the upstream three materials of ABS, which belong to the petrochemical chain, has been dragged. Overseas supply of acrylonitrile will continue to be tight within the month, but domestic industry maintenance facilities are gradually returning, leading to relaxed supply expectations. At the same time, downstream consumption is limited, and acrylonitrile prices are weakly consolidating.
The domestic butadiene market fluctuated and weakened in May. Although the market is showing a weakening of cost support, some companies are maintaining a shutdown and maintenance status, and there is no increase in industry supply. Midstream merchants still have the willingness to raise prices. Combined with the recovery of industries such as synthetic rubber in the second half of the month, there has been some improvement in terminal demand. It is expected that a bottoming force in the butadiene market may form.
The overall trend of styrene market is fluctuating and falling. From the perspective of raw materials, pure benzene experienced a decline at the end of the month after consolidation. The consumption of styrene still lacks effective driving force, and the market lacks upward momentum. However, there are still expectations of a contraction in the supply of styrene, and it is expected that the decline in the styrene market in the future may be limited as a result.
In terms of demand: During the May period, there were limited changes in the start-up situation of downstream ABS enterprises. The main terminal appliance industry is gradually entering a off-season, with average consumption of appliance casings and no improvement in the profitability of terminal enterprises. The atmosphere inside the venue is buying up instead of buying down, and there has been a significant reduction in replenishing and building positions. However, in the early stages of profit taking by merchants, there was a tendency for them to sell at a lower price and then sell back, while the buyer camp showed a high level of resistance towards high priced goods. Overall, the demand side has poor support for the ABS market.
Future forecast
The domestic ABS market continued to decline in May. The production load of the aggregation plant has fluctuated narrowly, but the on-site supply remains within a sufficient range. Cost three materials are weakly organized. The current ABS market is shrouded in a bearish trend of weakened demand. At present, the focus of spot prices is loose, and on-site trading is relatively quiet.

As of May 29th, the price of 0 # zinc was 24842 yuan/ton, an increase of 0.11% compared to the price of 24814 yuan/ton on May 25th.
supply side
The shortage of mining resources has formed strong support. The processing fee continues to decline, and the domestic zinc concentrate TC weekly ratio has dropped to 550 yuan/ton. The imported ore rich ore quotation is -70~-60 US dollars/ton, and the profit loss of smelters has intensified, with expectations of maintenance and production reduction. Factors such as overseas supply disruptions, the Kazakhstan zinc plant explosion, and changes in Peru’s mining policies have led to a tightening of global zinc concentrate supply. Domestic production is limited, and the tight supply of raw materials and low TC pattern limit the room for increasing zinc ingot production. The production in May is expected to contract month on month.
However, the short-term supply of refined zinc spot is still relatively abundant. Smelting enterprises have only slightly reduced production this week, and there has been no centralized maintenance. The supply contraction has not yet been transformed into a significant destocking of spot, which is currently more reflected in emotional and expected support.
Demand side
There is a marginal rebound during the off-season. Traditional off-season characteristics: The operating rates of galvanizing, die-casting, and zinc oxide have all fallen, and the demand for infrastructure and real estate is weak. Structural highlights: Data shows that orders from domestic galvanizing industry and steel structure enterprises have rebounded, and downstream procurement enthusiasm has increased. Improvement in export margin: After the adjustment of the Shanghai London price ratio, the export window margin has opened, easing domestic inventory pressure.
comprehensive analysis
This week, zinc prices have shown a pattern of strong fluctuations in the game between strong support from the mining sector and suppression from the off-season demand. It is expected that zinc prices will continue to fluctuate strongly within the range.
