2、 Market analysis
According to the commodity analysis system of Shengyi Society, the price of baking soda is running steadily, and the company’s shipments are still acceptable. The price of baking soda in Henan region is running weakly, with a factory price of 1200 yuan/ton in Henan region and 1200-1300 yuan/ton in Shandong region. Due to downstream demand driven procurement, it is expected that weak operations will be the main focus in the later stage. Upstream: According to the commodity analysis system of Shengyi Society, the price of soda ash is operating steadily. The current market average price is 1166 yuan/ton, a decrease of 39.46% compared to the same period last year, and downstream purchases are mostly made on demand.
Business Society analysts believe that the price of baking soda has been consolidating recently, with the upstream raw material soda ash generally operating in the near future. Downstream baking soda is mostly purchased on demand in pharmaceuticals, textiles, food, and other fields, with average demand enthusiasm. Overall, it is expected that the price of baking soda will mainly consolidate in the later stage, depending on downstream market demand.

According to the commodity analysis system of Shengyi Society, the market for locally refined petroleum coke continued to rise in mid July. As of July 21, the price of locally refined petroleum coke in the Shandong market was 2330.00 yuan/ton, an increase of 2.19% from 2280.00 yuan/ton on July 11.
The crude oil market has been fluctuating recently. The crude oil market is affected by both bullish and bearish factors. On the one hand, OPEC+has released its annual world oil outlook and lowered its energy demand expectations, putting pressure on oil prices. On the other hand, the geopolitical situation in the Middle East has led to increased sanctions against Russia by the United States, and the United States will impose a 30% tariff on most imported goods from the European Union and Mexico from August 1st, causing fluctuations in the crude oil market.
In mid July, the shipment of petroleum coke from local refineries was still acceptable, and downstream demand for carbon for aluminum remained stable. The stocking operation of negative electrode materials was active, and coupled with low inventory of petroleum coke in some refineries, it was favorable for the petroleum coke market, resulting in an overall increase in petroleum coke prices. Recently, the trading of petroleum coke at ports has been average. In the early stage, petroleum coke arriving at the port was gradually stored, and the main focus was on destocking at the port. Downstream enterprises maintained their essential procurement.
Recently, the market for calcined coke has remained stable, with an overall increase in the cost of petroleum coke. However, the price of medium and high sulfur calcined coke has been affected by negative demand, and most production enterprises have remained stable.
Market forecast: Currently, the petroleum coke market is trading well, with downstream demand purchasing supporting the petroleum coke market. Refinery inventories are not under pressure, and it is expected that petroleum coke will steadily rise in the near future.

Last week (July 14-20, 2025), the market trend for high-speed spinning of raw material nylon PA6 slices declined, with weakened cost support and high inventory levels in the market. The supply side performed well, while the demand side remained weak. Some nylon filament manufacturers had poor shipments, and low-priced sources increased in the market. Amidst mixed news in the market, the price of nylon filament continued to decline.
Nylon filament prices continue to decline
According to the Commodity Market Analysis System of Shengyi Society, last week (July 14-20, 2025), the price of nylon filament fell weakly. As of July 20, 2025, DTY (premium product) of nylon filament in Jiangsu region; 70D/24F) quoted 14460 yuan/ton, a decrease of 240 yuan/ton compared to the previous period, with a weekly decrease of 1.63%; Nylon POY (premium product; 86D/24F) quoted 12200 yuan/ton, a decrease of 200 yuan/ton compared to the previous period, with a weekly decrease of 1.61%; The price of nylon FDY (premium product: 40D/12F) is reported at 15050 yuan/ton, a decrease of 275 yuan/ton from the previous period, with a weekly decline of 1.79%.
Insufficient support on the raw material side
In terms of cost: Last week (July 14-20, 2025), the spot market price of caprolactam was weak during the week, with Sinopec’s high-end caprolactam closing price of 9095 yuan/ton. The nylon PA6 chip market experienced a slight decline, indicating insufficient support on the cost side. As of July 20, 2025, the benchmark price of caprolactam in Shengyi Society was 8943 yuan/ton, with a weak price and a weekly decline of 0.43%. During the week, the market price of high-speed spun nylon PA6 slices slightly decreased, with weak cost support being the main factor.
Supply and demand: During the week, some nylon filament manufacturers have lowered their operating rates, resulting in a decline in overall market supply. However, industry inventory levels continue to increase, leading to poor performance on the supply side; The demand in the end market is weak, and some downstream manufacturers have reduced production or switched production, resulting in a decrease in demand for nylon filament. It is difficult to find favorable support from the demand side, and many parties are following suit with rigid demand. Many industry players are adopting a cautious and wait-and-see attitude.
Future forecast
Cost aspect: In terms of caprolactam, the expectation for pure benzene is weak, and slice manufacturers have low enthusiasm for purchasing caprolactam. It is expected that the caprolactam market will continue to decline next week; In terms of PA6 slicing, cost support is limited, and the supply level of PA6 slicing market may continue to improve. Downstream market demand is weak, and it is expected that the market price of nylon PA6 slicing will decline.
Supply and demand: July belongs to the off-season of traditional demand in the market, and coupled with the lack of signs of improvement in terminal market demand, downstream market procurement enthusiasm is not high. Therefore, it is expected that the demand for nylon filament market next month may decrease. If there is no significant improvement in demand, under the pressure of large inventory, some nylon filament manufacturers may have the possibility of reducing production capacity, while the industry continues to release new production capacity. Therefore, it is expected that the supply of nylon filament market will decrease next month.

Overall, both the upstream raw material caprolactam spot market and the nylon PA6 chip market are likely to continue to decline, with a lack of cost support and difficulty in improving downstream market demand. The demand side is dragging down market trends, and under the dual negative factors, analysts from Shengyi Society predict that the short-term nylon filament market prices will continue to be weak, with a expected decline of 100-300 yuan/ton.

According to the Commodity Market Analysis System of Shengyi Society, the overall PTA market in China maintained a weak trend this week (July 14-18). As of July 19, the average price of PTA market in East China was 4776 yuan/ton, a decrease of 0.28% from the beginning of the week. In the second half of the week, the price slightly increased due to the boost of crude oil.
The domestic PTA supply remains stable, with no new changes in equipment, and the overall operating rate of the industry is around 80%. Among them, the 2 million ton plant of Yisheng Hainan reduced its load on July 1st due to some reasons, and increased its load on July 6th. In June, the 4.5 million ton plant of Fuhai Chuang and the 2.5 million ton plant of Dongying Weilian were still shut down.
The international crude oil market is currently characterized by loose supply and poor demand, coupled with the overall easing of the geopolitical situation compared to the previous period, which has limited support for oil prices and mainly led to fluctuating adjustments. As of July 17th, the settlement price of the August WTI crude oil futures contract in the United States was $67.54 per barrel, and the settlement price of the September Brent crude oil futures contract was $69.52 per barrel.
The terminal has entered a seasonal off-season, with insufficient demand support and hindered procurement enthusiasm. Downstream polyester factories have once again released statements of production reduction, which is bearish for the market mentality. Currently, the industry’s operating rate is at 86%, and under the pressure of losses, plans are being made to implement a 10% production reduction. The demand in the weaving industry has been affected, with high inventory, shortage of orders, and losses leading to a continued decline in load to below 56%.
Business analysts believe that the traditional off-season terminal negative feedback continues, and the buying and selling atmosphere in the PTA spot market is flat. The expectation of PTA capacity expansion combined with downstream polyester production reduction is expected, and the PTA market price fatigue range is expected to consolidate.

According to the Commodity Market Analysis System of Shengyi Society, the domestic PP market fluctuated weakly in the first half of July, with some brand products experiencing narrow price reductions. As of July 15th, the mainstream offer price for wire drawing by domestic producers and traders is around 7366.67 yuan/ton, a decrease of -1.23% compared to the price level at the beginning of July.
price trend
In terms of raw materials:
Since the beginning of July, the geopolitical situation in the Middle East has eased, and the market’s concerns about the risk of crude oil supply interruption have eased. At the same time, OPEC+has a firm willingness to increase production, and international oil prices are under pressure and fluctuating. In terms of propane, it has followed the decline of crude oil in the early stage, and consumption has been sluggish. It has continued to decline for the past half month, and the cost support for PDH manufacturing enterprises has fallen. Acrylic production and resumption of work are common, and the market continues the downward trend from last month. Overall, the prices of PP raw materials in the first half of July provided weak support for costs.
Supply side:
Since July, domestic PP enterprises have been undergoing centralized maintenance, while resuming work and releasing production capacity have also been concentrated. Overall, the overall load level within the interval has slightly decreased from 77% at the beginning of the month to 76%, and the weekly average total output has remained stable at around 770000 tons. The supply of goods remains abundant, with a monthly inventory of 790000 tons in China, and the digestion situation is average. Overall, the supply side provided moderate support for PP spot prices in early July.
In terms of demand:
July is the traditional off-season for polypropylene consumption, and the demand for PP continues to be weak, resulting in a quiet trading atmosphere on the market. Merchants have hardly seen any advance stocking operations, and the on-site situation remains in a state of urgent need, with a focus on on-demand use. In terms of plastic weaving, the consumption level of terminal enterprises is already at the off-season level, and downstream PP enterprises in China are struggling to start production. Materials used in construction, agriculture and other fields are also at a low level and flat. On site new orders tend to be scattered small orders and contract deliveries, with flat liquidity of supply and slow release of PP demand. In the context of weak export and domestic demand, the demand side of PP has not provided strong support for spot prices.
Future forecast
The domestic PP market prices fluctuated after falling in the first half of July. Fundamentally speaking, the overall weakness of upstream raw materials has led to a decline in overall support for PP. The industry load is stable with small fluctuations, and there is an expectation of abundant supply in the future. Consumption is at a low season level. The contradiction between supply and demand and the decrease in cost value are combined, and the mentality of operators is bearish. It is expected that the PP market will continue to be stagnant in the short term.
