This week (5.12-5.16), the polyethylene market rebounded. The favorable tariff policies between China and the United States have led to an increase in cost side oil prices, which is favorable for the rebound of the polyethylene market. The maintenance of the supply side equipment has eased the supply pressure on site, and the inventory of rising petrochemical enterprises and intermediaries has been reduced. Agricultural film is in the off-season of demand, and the operating rate has declined compared to the previous period, with insufficient support from the demand side. In terms of exports, some enterprises have seen an improvement in their export orders. As the weekend approaches, the rise in polyethylene prices has weakened, and the willingness of end-users to accept high priced goods has decreased, resulting in a slowdown in transactions. The market is mainly digesting the previous gains. The supply and demand of polyethylene face limited market support. Macro environment preference, polyethylene is expected to have a strong trend in the short term.

The domestic acrylonitrile price began to consolidate horizontally at the end of April, and on May 13th, this stalemate was finally broken. Manufacturers’ quoted prices showed a slight increase. As of May 16th, the mainstream negotiation for container self pickup at East China ports remained at 8500-8600 yuan/ton, an increase of 300-400 yuan/ton from last week; Short distance delivery to the Shandong market remains at around 8350-8500 yuan/ton, up 400-450 yuan/ton from last week.
Before and after the May Day holiday, the acrylonitrile market was in a state of weak supply-demand balance, with some equipment maintenance leading to tight supply. However, the inventory of acrylonitrile factories was controllable, and coupled with no significant improvement in downstream demand, the operating rate of the main downstream ABS industry was only 69%. Manufacturers’ willingness to raise prices and weak demand balanced each other, and the transaction center of East China ports remained in the range of 8100-8300 yuan/ton. Entering this week, local spot supply has tightened, and factories have shown a clear willingness to raise prices under low profits, thus driving the spot market up to 8500-8600 yuan/ton.
At the same time, the price of raw material propylene continues to rise, with the mainstream price in Shandong region ranging from 6500-6700 yuan/ton, and cost pressure is transmitted to the acrylonitrile production end.
At present, the profit situation of the acrylonitrile industry is not optimistic. On the one hand, the demand for terminal home appliances and the automotive market appears weak, and the resistance to high priced raw materials continues to rise. Downstream industries such as ABS and acrylic continue to have low operating rates. On the other hand, the supply of acrylonitrile is increasing. Due to multiple factors, the upward potential of acrylonitrile prices is limited, and profit margins are squeezed. Since March, acrylonitrile factories have been in a loss making state, and their willingness to repair profits is very strong.
It is worth noting that the suspension of tariffs between China and the United States is limited to 90 days. If no consensus is reached in subsequent negotiations, companies may face a second round of “export competition” pressure, leading to increased supply chain fluctuations. In terms of terminals, export orders in small household appliances, consumer electronics and other fields have rebounded rapidly, and enterprises have locked in profits by stocking up in advance. The demand for some nitrile gloves will also increase significantly.
However, Zhenhai Refining and Chemical has a start-up plan in June, and coupled with the successful trial production of the 260000 ton/year unit of Sinochem Quanzhou Petrochemical in April, the total domestic acrylonitrile production capacity will be greatly increased, and the supply increment will enter an accelerated release stage. The increment brought by the new unit’s commissioning far exceeds the periodic shutdown loss, and the supply side pressure is enormous. On the other hand, downstream industries such as acrylic fiber and acrylamide only maintain rigid demand, making it difficult to absorb new production capacity.
Overall, factories have reacted quickly to the recent increase in acrylonitrile prices, and the spot market has mostly followed the factory’s upward trend. However, due to limited downstream substantial demand, although the acrylonitrile market price will increase significantly in the short term, the sustainability of the upward trend is not stable, and caution should be exercised in the operation process.

1、 Price trend
According to the Commodity Market Analysis System of Shengyi Society, the average price of ammonium sulfate in the domestic market on May 15th was 1060 yuan/ton, which was 1.24% lower than the average price of 1073 yuan/ton on May 9th.
2、 Market analysis
The price of ammonium sulfate in the domestic market has fallen this week. The operating rate of coke enterprises does not fluctuate significantly, and some caprolactam enterprises are operating at a reduced load. This week, the bidding price for coking grade ammonium sulfate has been lowered, and the price for domestic grade ammonium sulfate has slightly decreased. At present, the demand for ammonium sulfate in the market is light, and downstream inquiries have decreased. Therefore, caution and observation are the main focus. As of May 15th, the mainstream ex factory quotation for coking grade ammonium sulfate in Shandong region is around 990 yuan/ton. Domestic grade ammonium sulfate, the mainstream ex factory quotation in Shandong region is around 1045-1090 yuan/ton.
3、 Future forecast
An ammonium sulfate analyst from Shengyi Society believes that the recent trend of the ammonium sulfate market is mainly downward. At present, downstream demand for replenishment is high, and there is resistance to high prices, leading to a strong bearish sentiment in the market. It is expected that in the short term, the domestic ammonium sulfate market price will be weak and mainly operated through consolidation.

Recently (5.1-5.12), the butadiene rubber market has slightly improved. According to the commodity market analysis system of Shengyi Society, as of May 12th, the butadiene rubber market price in East China was 12010 yuan/ton, an increase of 0.50% from 11950 yuan/ton at the beginning of May. The price of raw material butadiene has dropped significantly, and the cost center of butadiene rubber has shifted downwards; The production of butadiene rubber has increased, and the pressure on the supply side has slightly increased; In April, the production of semi steel tires in the downstream remained stable, while the production of all steel tires slightly decreased, which slightly weakened the support for the demand for butadiene rubber. As of April 29th, the mainstream prices for Qilu, Daqing, Sichuan, and Yangtze Shunding in East China were 11850-12250 yuan/ton.
Recently (5.1-5.12), the price of butadiene has slightly increased, and the cost center of butadiene rubber has shifted upward. According to the Commodity Market Analysis System of Shengyi Society, as of May 12th, the price of butadiene was 9333 yuan/ton, an increase of 2.94% from 9066 yuan/ton at the beginning of May.
Recently (5.1-5.12), the construction of domestic butadiene rubber plants has significantly increased, with the overall construction rate rising from around 6.70% at the end of April to around 7.50%, resulting in increased pressure on the supply side of butadiene rubber.
Demand side: Recently (5.1-5.12), downstream tire production has significantly decreased, which has weakened the support for the butadiene rubber market. As of May 9th, the operating load of semi steel tires in domestic tire enterprises is around 5.8%; The operating load of all steel tires in tire enterprises in Shandong region is about 4.5%.
Market forecast: From a fundamental perspective, analysts from Shengyi Society believe that the price of butadiene will slightly increase in the short term, and the cost support for butadiene rubber will still be weak; The decline in downstream production has a bearish impact on Shunding Rubber, with weak transactions. Overall, it is expected that the Shunding Rubber market will consolidate weakly in the later period.
