According to the monitoring of the commodity market analysis system of Shengyi Society, the 1 # tin ingot market in East China region rose this week (4.21-4.27), with an average market price of 258920 yuan/ton at the beginning of the week and 263010 yuan/ton at the end of the week, with a weekly increase of 1.58%.
From a macro perspective, the United States announced the imposition of tariffs on Chinese goods, covering key areas of tin consumption such as home appliances and consumer electronics. This measure has led to a weakening trend in export expectations for related products.
On the supply side, Alphamine officially announced that its Bisie mine is resuming production and operation in an orderly and phased manner as planned. However, given the significant delay in the resumption of tin ore production in Myanmar, the market’s expectation of overall tin ore supply tightening still persists.
On the demand side, the current trading performance of the tin ingot market is relatively quiet, and the trading heat has not significantly increased. Downstream enterprises’ procurement behavior is based on rigid demand, and when prices are in the low range, the demand for replenishment is timely released, driving a small amount of trading activity. However, as the price of tin ingots gradually rises, the trading activity in the spot market has significantly decreased, and the willingness of buyers and sellers to trade has cooled down. The procurement strategy of downstream solder enterprises also shows the dominant feature of rigid demand, meeting daily production needs while moderately replenishing inventory in combination with market price fluctuations. It is worth noting that the “trade in” policy continues to exert efforts, forming positive incentives for consumers’ purchasing intentions and indirectly driving demand for end products such as household appliances; In addition, the production schedule of the home appliance industry is running at a high level, and the production scale continues to expand. The combined effect of the two provides potential support for the demand side of tin ingots, and the potential for future demand release is worth paying attention to.
comprehensive analysis
The progress of resuming tin ore production in Myanmar is significantly lagging behind market expectations, coupled with limited recovery of Indonesian exports. The supply gap is difficult to effectively fill through internal adjustments or external supplements in the short term, and the global tin resource supply shortage is expected to continue in the short term. Expected to fluctuate widely within the tin price range.

According to the monitoring of the commodity market analysis system of Shengyi Society, the magnesium ingot market in Shaanxi Province rose this week (4.14-4.18), with an average market price of 16450 yuan/ton at the beginning of the week and 16750 yuan/ton over the weekend, an increase of 1.82%.
Affected by the aftermath of last week’s sharp decline in market prices, industry participants’ confidence was generally dampened at the beginning of this week, and market trading prices continued to show a slight downward trend; By the second half of the week, with downstream user inventory levels basically dropping to a low level, driven by concentrated replenishment demand, the market price of magnesium products quickly rebounded, forming a significant rebound trend.
Supply and demand side
On the supply side, the original magnesium production is showing a continuous contraction trend, and magnesium factories are extremely determined to raise prices based on cost support and profit considerations. When market prices are in the low range, multiple magnesium factories adopt a strategy of suspending quotations to reduce the impact of low-priced transactions on the price system. This supply side’s reluctance to sell has enabled market prices to quickly rebound. On the demand side, at the beginning of the week, downstream enterprises showed a strong wait-and-see attitude due to the inertia of previous price declines, and their procurement actions tended to be cautious. However, as inventory levels gradually decrease and market prices approach the recent bottom, downstream enterprises actively enter the market to purchase and replenish goods to ensure production continuity.
Raw material end
The price of coal raw materials relied on for the production of blue charcoal has experienced a certain degree of decline. Due to this transmission effect, the market price of blue charcoal has also shown a weakening trend. At the same time, the price of silicon iron has also entered a downward adjustment mode. In this situation, the overall support of the cost side for the prices of related products has weakened.
comprehensive analysis
In summary, against the backdrop of no significant fluctuations in current supply, there is an overall dynamic balance pattern between supply and demand. Expected short-term price fluctuations within the range.

According to the Commodity Market Analysis System of Shengyi Society, the domestic polyester staple fiber market weakened slightly this week (April 21-25). As of April 25, the average market price of domestic polyester staple fiber (1.4D * 38mm) was 6294 yuan/ton, a decrease of 0.37% from the beginning of the week.
On April 22nd local time, US President Trump announced at a White House press conference that the high tariffs imposed on goods from China will be significantly reduced. The trade friction caused by tariff issues has eased, and market sentiment has improved, providing some support for oil prices. As of April 24th, the settlement price of the main contract for WTI crude oil futures in the United States was $62.79 per barrel, and the settlement price of the main contract for Brent crude oil futures was $66.55 per barrel.
Under the boost of the crude oil market, the average market price in East China as of April 25th was 4493 yuan/ton, up 3.78% from the beginning of the week. Recently, PTA plant restarts and maintenance coexist.
Under the influence of tariffs, the market fluctuates greatly, and downstream yarn factories are cautious in purchasing goods, mainly focusing on digesting inventory. The production of weaving machines in Jiangsu and Zhejiang provinces continues to decline by around 60%, and the export of terminal textiles and services is hindered due to the disturbance of tariff policies, which has a negative feedback impact on the upstream. The downstream production rate is likely to decline during the May Day holiday, and demand will further decrease.
Business analysts believe that the cost side support is still acceptable, and there is an expectation of reduced PTA supply. There will still be equipment maintenance next week. However, the terminal performance is weak, and downstream purchases are mainly based on demand. Under the unstable external factors, the market lacks drivers and tends to adopt a wait-and-see attitude. It is expected that the short-term prices of polyester staple fibers will experience a slight consolidation.

According to the Commodity Market Analysis System of Shengyi Society, as of April 24, 2025, the reference price of n-butanol in Shandong Province, China is 6283 yuan/ton. Compared with April 1 (reference price of n-butanol is 6633 yuan/ton), the price has decreased by 350 yuan/ton, a decrease of 5.28%.
Since April, the overall n-butanol market in Shandong region of China has shown a trend of first rising and then falling. In early April, the n-butanol market saw an upward trend, with market prices continuously rising and the focus of negotiations shifting upwards. On April 7th, n-butanol rose to a monthly high, with a reference of 6783 yuan/ton. Subsequently, after a brief period of market consolidation, the n-butanol market suddenly began to decline, with market prices continuously adjusting downwards and the focus of transactions continuously decreasing. As of April 24th, the n-butanol market price in Shandong region was referenced at around 6250-6400 yuan/ton, with a price reduction of 100-300 yuan/ton for the month.
Analysis of Market Factors
On the supply side: At the beginning of the month, some equipment in the n-butanol plant was undergoing maintenance, resulting in overall shortage of n-butanol supply and low pressure on the supply side, which provided upward support for the market. Subsequently, the n-butanol plants resumed production one after another, and the supply pressure on the n-butanol plant increased. The support provided by the supply side to the market weakened. Most n-butanol factories in Shandong began to sell at a discount to maintain low inventory, and the n-butanol market price began to decline.
On the demand side: At the beginning of the month, there was small-scale stocking of n-butanol downstream, and demand transmission was still acceptable, providing certain support to the market on the demand side. From mid month to the end of the month, as the n-butanol market continued to decline, downstream users became increasingly cautious and cautious in stocking up. Demand side support loosened, and the contradiction between n-butanol supply and demand gradually emerged.
Market analysis in the future
At present, the trading atmosphere of n-butanol in the market is mild, and the effective supply of n-butanol in the market is still insufficient. The supply of goods in the market is relatively sufficient. Currently, the market has fallen to a low point, and downstream suppliers are restocking at low prices. The n-butanol data analyst of Shengyi Society believes that in the short term, the n-butanol market in Shandong Province will mainly adjust and operate in a narrow range, and specific changes in supply and demand news need to be closely monitored.

According to the Commodity Market Analysis System of Shengyi Society, as the end of April approaches, the domestic PP market is weakly consolidating, and the prices of most brand products have fallen. As of April 23rd, the mainstream offer price for wire drawing by domestic producers and traders is around 7523.33 yuan/ton, a decrease of -0.53% compared to the price level at the beginning of April.
price trend
In terms of raw materials:
In early April, the US tariff policy was implemented, with tariff rates constantly changing and increasing to unprecedented heights. The tariff trade war launched by Trump has had a huge impact on the global economy. Crude oil, as a heavily affected area, has experienced a sharp drop in prices. However, recently some members of OPEC+have announced plans to compensate for overproduction, and the expectation of production contraction is clear. Combined with the increasingly tense geopolitical situation in Eastern Europe and the impact of various boosting factors, oil prices have rebounded from low levels. At the same time, domestic propane prices have risen due to the impact of trade decoupling, but the increasing cost pressure has dragged down the production and profitability of PDH manufacturing enterprises. The downstream production position of propylene is not high, and there is insufficient chasing power on site, resulting in price fluctuations after rising. Overall, the prices of various raw materials at the end of April have slightly rebounded to support the cost of PP.
Supply side:
Recently, domestic PP enterprises have experienced significant fluctuations in their workload, and the market supply has remained generally abundant. Overall, the current industry’s overall load level has slightly decreased by about 1% to 78% compared to the middle of the month. The average weekly production in China is about 750000 tons. Recently, Zhongsha Tianjin, Changling Petrochemical and other enterprises have successively entered maintenance. Later, Zhejiang Petrochemical and middling coal Yulin have announced their parking plans. On the whole, maintenance is intensive, loss of capacity is expanded, and supply and contraction are expected in the future. There is an upward trend in the supply side’s support for PP spot prices.
In terms of demand:
Recently, the demand for PP has been relatively weak, and on-site trading has maintained a weak rigid demand pattern. In terms of plastic weaving, the consumption level of terminal enterprises has generally stabilized. The demand for PP in fields such as architecture and agriculture is gradually increasing with the warming of temperatures. However, under the influence of international news such as equivalent tariffs imposed by the United States, the global economy has been greatly impacted and future uncertainty has increased. The export of downstream PP products in China is hindered, and buyers tend to maintain production with scattered small orders. Although there has been no significant increase in new orders in the market. Overall, the demand for PP weakened at the end of April.
Future forecast
Recently, the domestic PP market prices have been weakly adjusted. From a fundamental perspective, the comprehensive performance of upstream raw materials on PP support has risen at a low level, with abundant industry supply and weak demand support in consumption. The current industry trend is focused on the struggle between supply contraction and weak consumption, with cautious on-site operations and frequent avoidance of suspicion in small orders. In the short term, the supply-demand imbalance is unlikely to improve. It is recommended to closely monitor the situation of tariffs and the flow of goods.
