price trend
According to data from Shengyishe Spot News, since mid April, the domestic PC market has experienced a high-level decline, with most brands experiencing an overall decrease in spot prices. As of April 2nd, the mixed benchmark price of Business Society PC was around 16133.33 yuan/ton, a decrease of 2.52% from the beginning of the month.
Root cause analysis
Supply side: Since April, domestic PC aggregation enterprises have been relatively concentrated in maintenance. However, overall, the load within the range has been reduced by 7%, and the current average operating rate is around 80%, with limited reduction. At present, the average weekly output is within 70000 tons. There is not much room for contraction in the future supply, but overall, the supply side’s support for PC is still acceptable.
In terms of raw materials, it can be seen from the above chart that the domestic bisphenol A market has gradually declined since early April. Affected by the sharp decline in international crude oil prices, the prices of phenol and acetone have remained stagnant and fallen. Subsequently, it caused a drag on the price center of bisphenol A in China. At the same time, the current supply of bisphenol A has limited changes and demand has weakened. Merchants are actively shipping and tend to sell at discounted prices. The overall support for PC cost value has weakened.
On the demand side: The profitability of terminal enterprises has not improved, and the load position of downstream PC factories is still relatively low. Although the current PC price has fallen from a high level, it is still within the three-year high range. The buyer is cautious in stocking up and has a poor willingness to build a warehouse. The market has a strong wait-and-see atmosphere, and the liquidity of goods has decreased. In the early stage, the atmosphere of PC market speculation has basically cooled down, and the mentality of merchants has weakened. They offer according to the market, and there has been an increase in profit giving and order taking operations. Overall, the demand side has poor support for PC spot prices.
future market forecast
In late April, the domestic PC market continued to decline at a high level. The price of upstream bisphenol A continues to weaken, causing a drag on the cost value of PC. The load of domestic PC aggregation plants has slightly decreased, and the supply side benefits are limited. On site trading is mainly based on weak demand, and buyers have a cautious mentality, taking whatever they need. Trading is mostly small orders. It is expected that in the short term, the PC market may continue to be suppressed by the decline in the upstream market, and there may still be room for downward adjustment.

According to data from Shengyishe Spot News, in April, the supply of hydrogen peroxide in the market became tight, while the demand side improved, providing dual support and causing a significant increase in prices. Prices have entered the era of “four digits”. At the beginning of the month, the average market price of hydrogen peroxide was 796 yuan/ton. On April 21st, the average market price of hydrogen peroxide was 1033 yuan/ton, an increase of 29.71%.
Reasons for the rise in the current hydrogen peroxide market
On the demand side: In late April, the pre holiday stocking market arrived, and epoxy propane enterprises in the northern region continued to purchase, with strong digestion capacity; At the same time, the increase in operating load of the caprolactam factory has increased the demand for hydrogen peroxide. Downstream industries such as papermaking and new energy (iron phosphate) have also conducted centralized procurement, providing strong support for the market
Inventory and supply situation: Production enterprises have abundant orders, and the overall inventory level continues to decline, with many water companies even experiencing the phenomenon of controlling quantity and shipping. Low inventory levels provide a solid foundation for price increases. Hydrogen peroxide companies in Shandong, Anhui, and Sichuan regions have stopped for maintenance, while some companies in Hangzhou have limited production. The temporary shortage of supply has driven the hydrogen peroxide market to soar.
In summary, in late April, domestic hydrogen peroxide was already at a historical high. After the May Day holiday, the stocking market ended, and the pressure of loose supply remained. Terminal demand fell, and the hydrogen peroxide market gradually experienced a pullback.

According to the Commodity Market Analysis System of Shengyi Society, the price of formic acid has shown a weak and stable trend recently. As of April 20th, the benchmark price of 85% industrial grade formic acid in China was 2800 yuan/ton, unchanged from the previous month and decreased by 17.65% year-on-year.
The fundamental supply is sufficient, and the manufacturer has lowered the quotation
The supply of formic acid has always been sufficient, with stable supply sources. Although there has been no shortage of supply, the overall upward momentum is lacking, and the support for prices is weak. This is also one of the core factors that make it difficult for prices to recover. At the same time, although the overall inventory of the industry has been supported by a low level, with the recent flat demand, the market inventory has shown a cumulative trend, further exacerbating the downward pressure on prices.
The demand side performance is flat, and the purchasing willingness of domestic downstream enterprises is weak, mainly focusing on obtaining goods for essential needs. There has been no large-scale centralized procurement behavior, making it difficult to effectively drive prices; In terms of exports, most of the orders are delivered in the early stage, and there are few new orders added, which cannot provide strong support for the market situation. The wait-and-see sentiment in the downstream market continued to heat up after the early price reduction, causing manufacturers to slow down their shipping pace and increasing inventory pressure on enterprises, further driving down prices.
Some manufacturers have made early preparations to cope with the upcoming May Day holiday, while taking advantage of the current profitable window to grab more orders and actively lowering their quotations, which has become an important driving factor for the slight decline in initial prices.
It is expected that the price of formic acid will continue to remain weakly stable.

1、 Trend analysis
According to monitoring data from Shengyi Society, copper prices first rose and then fell this week. As of the 17th, copper prices were reported at 102035 yuan/ton, an increase of 3.2% from the beginning of the week and a year-on-year increase of 34.05%.
Copper weekly fluctuation chart
According to the weekly chart of Shengyi Society, copper prices have risen slightly this week, with a decrease of 7 and an increase of 6 in the past three months.
LME copper inventory
According to data released by the London Metal Exchange (LME). LME copper inventory has slightly increased, with 400225 tons of LME copper inventory as of the weekend, up 0.27% from the beginning of the week.
Macroscopically, the achievement of the ceasefire agreement is undoubtedly a shot in the arm for market sentiment. It directly alleviated the extreme concerns of the market about the interruption of shipping in the Strait of Hormuz, leading to a decline in crude oil prices and thereby reducing the cost pressure on industrial metals. The US dollar index continued its 9 consecutive declines, further providing upward momentum for metals priced in US dollars.
Supply side: The global decline in copper ore grades is a long-term structural problem, and the decline in production in major producing areas such as Chile has become a fact. More importantly, the copper concentrate processing fee (TC) has fallen to negative values (-78 USD/dry ton), which means that smelters are losing money for every ton of electrolytic copper produced, inevitably forcing them to lower their operating rates and tighten the supply of refined copper from the source. The sulfur shortage concerns caused by the situation in the Middle East are becoming a new variable affecting supply. Large wet copper producing countries such as the Democratic Republic of Congo are highly dependent on imported sulfuric acid. Once the supply is disrupted, it will directly restrict the global production of electrolytic copper.
On the demand side: Although the domestic GDP grew by 5.0% year-on-year in the first quarter and the contribution rate of domestic demand increased, the specific copper consumption showed insufficient momentum. The real estate market remains sluggish and difficult to form an effective driving force; And the photovoltaic sector has also brought negative news, with a year-on-year decrease of 20.60% in solar cell production in March. The weakness of traditional pillar industries has led to a lack of solid buyers for high copper prices.
New energy vehicles and high-end manufacturing industries such as AI computing power and robots have maintained a high level of prosperity. China Minmetals Corporation predicts that refined copper consumption in China will continue to maintain an average annual growth rate of 3.7% in the next decade, with this increase mainly coming from these new quality production areas. However, the incremental growth in emerging fields is not yet sufficient to fully offset the decline in traditional real estate infrastructure, and is extremely sensitive to prices.
In summary, mining interference and potential sulfur shortages have established a solid cost floor, and Citibank’s increase in target price to $13000 reflects the consensus of institutions on long-term shortages, which limits the potential for deep price declines. But in the context of weak spot premiums and less than expected destocking, the rise in copper prices is also limited. Copper prices are currently in a subtle ‘high volatility period’. It is expected that copper prices will continue to fluctuate at a high level.

According to the Business Society Spot News, in the first half of April, the propylene glycol market showed a trend of “rising and then falling at a high level”. At the beginning of the month, the price rose sharply, but under the dual pressure of cost collapse and weakened supply and demand, it slightly decreased in the second half. As of April 16th, the average production price of propylene glycol in Shandong was 11433 yuan/ton, with a cumulative increase of 10.65% in half a month.
fundamental analysis
Supply and demand situation
Supply side: Some domestic propylene glycol units have completed maintenance, and the operating rate has rebounded. However, the overall supply is still tight, and manufacturers have a strong willingness to raise prices. The spot market supply is tight.
Demand side: Downstream unsaturated resin demand remains stable, but at high prices, downstream customers tend to be cautious in receiving goods, mainly purchasing small orders for essential needs, resulting in limited overall demand growth. The spot market for polyether polyols continues to operate weakly, with sufficient supply and some manufacturers promoting orders at lower prices, resulting in a lack of overall follow-up willingness. The demand for lithium battery electrolyte solvents still has some support, and long-term orders are relatively stable, but high prices have a certain inhibitory effect on spot purchases.
Weakened cost support
In early April, market concerns about Middle Eastern geopolitics and rising oil prices pushed up epoxy propane, which in turn led to speculative increases in propylene glycol; In mid April, the geopolitical risk margin eased, epoxy propane supply resumed, and market sentiment turned cautious. Epoxy propane was the first to rebound, while propylene glycol lagged behind due to tight supply and demand balance. The price of propylene glycol completely follows the cost transmission of epichlorohydrin.
Market forecast:
In the short term, it is expected that the propylene glycol market will continue to maintain a high and narrow range oscillation pattern, with a low probability of significant price increases or decreases. Attention should be paid to the fluctuation of epoxy propane prices, changes in the supply side, and changes in downstream demand. If high prices continue to suppress downstream purchasing enthusiasm, prices may face slight downward pressure.
