After the National Day holiday, there will be a concentrated downstream maintenance in October, especially during the PVC maintenance period. The export of calcium carbide has strengthened its impact on the market, and the mainstream ex factory price of calcium carbide has decreased. According to statistics, downstream demand further decreased in mid October, and the concentrated arrival after the holiday may accelerate the further decline in downstream procurement prices. The overall downward trend of the calcium carbide market in October was more obvious, and the relief of oversupply caused by downstream centralized maintenance is still the main factor affecting the price of calcium carbide.

According to the Commodity Market Analysis System of Shengyi Society, on October 13th, the ex factory price of cyclohexanone in Shandong Province, China was reference 6750 yuan/ton.

After the holiday, the market situation is not good, and cyclohexanone is weak and falling
From the commodity market analysis system of Shengyi Society, it can be seen that after the National Day holiday in October, the cyclohexanone market in Shandong Province, China, is weak. Some cyclohexanone factories and suppliers in Shandong have lowered their cyclohexanone shipment prices by about 100 yuan/ton. As of October 13th, the reference market price for cyclohexanone in Shandong region is around 6700-6800 yuan/ton.
Analysis of Factors Influencing Market Trends
In terms of demand: Currently, the downstream demand for cyclohexanone is average, with limited new orders from downstream chemical fiber users and loose support on the demand side.
Supply side: Currently, the overall supply source of cyclohexanone market in Shandong is sufficient, and the supply side is under pressure, resulting in a lack of support for the market.
In terms of cost: After the holiday, the market for raw material pure benzene fluctuated and weakened, providing weak cost support for cyclohexanone. According to the data monitoring system of Shengyi Society, on October 13th, the reference price of pure benzene was 5662 yuan/ton, a decrease of 3.36% compared to October 1st (5848.67 yuan/ton).
Market analysis in the future
At present, the trading atmosphere in the cyclohexanone market is relatively weak, and the mentality of industry players is average. The transmission between supply and demand is slow. The cyclohexanone data analyst from Shengyi Society believes that in the short term, it is expected that the cyclohexanone market in Shandong will mainly consolidate and operate weakly, and more attention should be paid to the changes in supply and demand news.

According to the Commodity Market Analysis System of Shengyi Society, starting from September 23rd, the domestic palm oil market has gradually risen, with prices increasing. During the National Day holiday, palm oil prices continued to rise in foreign markets, and after the holiday, palm oil opened with a significant increase, with spot prices following suit. On September 23rd, the average market price of palm oil was 8972 yuan/ton, and on October 9th, the average market price of palm oil was 9598 yuan/ton, with a price increase of 6.98%.
The bullish support has led to a significant increase in the palm oil market after the holiday
Since September 23rd, the palm oil market has strengthened. The boosting effect of Malaysian palm oil is limited. Among them, the palm oil production in Malaysia decreased by 2.42% month on month from September 1st to 30th, 2025. Malaysia’s palm oil production is expected to decline, while offshore palm oil futures prices are expected to rise. During the National Day holiday, Malaysia’s palm oil export data was strong, and inventory estimates were lowered. The overseas palm oil market continues to rise, with an increase of over 4%. Palm oil opened sharply after the holiday, with an opening price of 9452 yuan/ton and a closing price of 9570 yuan/ton, up 3.05% from September 30th. The futures market has been boosted, and the domestic palm oil spot market has also risen, with an average market price of 9600 yuan/ton and a daily increase of over 300 yuan/ton.
The palm oil analyst from Shengyi Society believes that the significant rise in the palm oil market this round is mainly due to the external market pull during the National Day period, which led to a supplementary increase. The market has risen too high, and after the sharp rise, it has gradually experienced a downward trend. In the fourth quarter, palm oil enters the peak season, and rigid demand increases. It is expected that the palm oil market will mainly fluctuate and rise in the future.

According to the Commodity Market Analysis System of Shengyi Society, the price of acetic acid continued to rise in September. As of September 30th, the price was 2640 yuan/ton, an increase of 210 yuan/ton or 8.64% compared to the acetic acid price of 2430 yuan/ton at the beginning of the month.
The acetic acid price market was strong in September. The utilization rate of acetic acid production capacity continued to decrease during the month, and the market inventory was not high. At the same time, downstream demand increased during the traditional peak season, and enterprise shipments were smooth. Manufacturers’ inventory continued to decline, and the market fundamentals showed less supply and more demand. The intention of industry players to rise continued, and the price of acetic acid continued to rise during the month.
The raw material methanol market is fluctuating and operating weakly. As of September 30th, the average price in the domestic market was 2237 yuan/ton, a decrease of 0.71% compared to the beginning of the month price of 2253 yuan/ton. The import volume of methanol at domestic ports continues to be high, and inventory pressure still exists. The mainland market is fluctuating due to supply and demand as well as cost factors. The continuous pressure on the supply side has led to the accumulation of enterprise inventory. The pre holiday inventory of enterprises combined with the impact of low-priced port sources has resulted in downstream production only on demand, and the monthly methanol market has once again declined.
Market forecast: Business analysts believe that the acetic acid market will remain strong and stable in the near future, with low capacity utilization on the supply side, little inventory pressure on enterprises, active downstream entry into the market, good trading atmosphere, and follow-up replenishment after the holiday. Market expectations continue to be optimistic, and it is expected that the acetic acid market will operate at a high level in the later period. Specific attention should be paid to downstream follow-up.

Zinc price in September
According to the Commodity Market Analysis System of Shengyi Society, as of September 30th, the zinc price was 21824 yuan/ton, a decrease of 1.14% from the zinc price of 22076 yuan/ton on September 1st.
In September, the center of gravity of zinc prices in Shanghai once again declined, showing a trend with the middle of the month as the dividing point – maintaining a consolidation trend in the early stage, and then breaking through the level to decline. This is mainly due to the weakening of macro level disturbance factors and the return of market trading logic to fundamentals. The weak trend during the peak consumption season has been confirmed, and the accumulation of inventory has suppressed prices. The domestic zinc ingot market presents a pattern of oversupply, with a weak internal and strong external fundamentals.
In terms of raw materials
In September, the import losses of zinc concentrate continued to intensify, and the import window was almost completely closed. Despite the expected arrival of lock up zinc concentrate and long-term single zinc concentrate at the port in the early stage, it is expected that the quantity of imported zinc concentrate will significantly decrease in October. During September, the price comparison between domestic and foreign markets deteriorated, and the profit loss of imported ore smelting further expanded. As a result, domestic smelters are more inclined to purchase domestically produced ore. At the same time, in order to promote the sales of imported goods, the mining trade has proactively increased the import TC. Looking ahead to October, it is expected that the domestic TC will slightly decrease, while there is still room for an upward adjustment in the import TC.
Supply and demand side
Recently, the market price of zinc has shown a downward trend, which has compressed the profit margin of the smelting industry. However, the profits generated by the by-products in the current smelting process are still considerable, which keeps the profitability of the smelter above 1000 yuan per ton. Therefore, the production enthusiasm of the smelter is still high. In September, some domestic smelters experienced a decrease in refined zinc production compared to previous months due to equipment maintenance. In October, as previously repaired smelters resume production, the supply of refined zinc in China is expected to increase to some extent.
Since the beginning of the month, there has been no obvious sign of recovery in the overall domestic consumer market. Even during the traditional peak consumption season, various consumer data performances are still below expected levels, and market vitality needs to be further stimulated. Based on the current economic situation and consumption trend analysis, it is expected that the domestic consumer market will still be difficult to show significant improvement in October, and the overall situation may remain stable and weak.
Future forecast
Entering October, it is expected that mines in northern China will experience production cuts or shutdowns, which may lead to a decrease in domestic zinc concentrate production. Correspondingly, it is expected that the processing fee (TC) for domestic zinc concentrate will be slightly reduced, while there is still a possibility of an increase in the processing fee for imported zinc concentrate. As the smelter undergoing maintenance in October gradually resumes production, the supply of refined zinc in China may increase. However, it is expected that there will be no significant improvement in the domestic demand for refined zinc consumption.
