1、 Price trend
Taking the sulfuric acid method for producing pyrite type titanium dioxide, which has a large volume of goods in the domestic market, as an example. According to data monitoring by Business Society, the domestic titanium dioxide market has shifted upwards this week. At the beginning of the week, the average price of titanium dioxide in the domestic market was 13480 yuan/ton, and the average price over the weekend was 13820 yuan/ton, with a price increase of 2.52%.
2、 Market analysis
This week, the domestic titanium dioxide market has shifted its focus upwards. At present, cost pressure still exists for titanium dioxide companies, and many are waiting to see if they can raise prices. Approaching the Golden September and Silver October, the market anticipates stocking up, and holders have no intention of continuing to sell at low prices, resulting in an increase in quoted prices. As of now, the domestic quotation for sulfuric acid based pyrite type titanium dioxide is mostly between 13200-14200 yuan/ton; The price of the titanium type is around 11700-12500 yuan/ton, and the actual transaction price is negotiable.
3、 Future forecast
Business Society’s titanium dioxide analyst believes that the focus of the domestic titanium dioxide market is shifting upwards this week. The cost of titanium dioxide enterprises is under pressure, and their quotations are firm. However, after downstream stocking up in the early stage, there is a lack of willingness to purchase in the near future, and the market is more cautious. It is expected that the titanium dioxide market will remain strong in the short term, with actual transaction prices subject to negotiation.

According to the price data from Shengyi Society, the polyester bottle chip market has been running weakly this week. As of September 5th, the average sales price of PET is 5897 yuan/ton. Decreased by 1.15% compared to the beginning of the week.
On the cost side: Crude oil prices have fallen this week, and the overall cost of polyester is weak and fluctuating. The collapse of cost support, coupled with downstream demand to maintain essential needs and replenish at low prices, has resulted in no substantial positive news on the supply and demand side, leading to an expansion of the decline in the PET market. The current situation presents a dual weak pattern of cost and demand, and the cost side has not provided strong support for the price of polyester bottle chips, which cannot drive price increases.
Supply side: Mainstream factories continue to reduce production, which provides some support for prices, but the buffering effect of supply regulation is limited, making it difficult to change the overall weak trend.
Demand side: Downstream demand is weak, with rigid procurement being the main focus. After the deep drop in prices on Thursday, some companies bought back their positions on dips, which slightly boosted trading and the overall market lacked the drive to increase volume.
Looking ahead to next week, the cost side is under pressure due to the expected poor quality of the “golden nine and silver ten” products, and the PET market price may fluctuate narrowly with the cost side in the short term. Terminals are often used and purchased on demand, and the market lacks the drive to increase volume. The actual trend still needs to pay attention to changes in external news, device changes, and demand recovery in the future. The price of bottle slices is expected to fluctuate weakly within the range of 5800-5950 yuan/ton.

2、 Market analysis
The soda ash market has been weak this week. The utilization rate of soda ash production capacity decreased during the week, and the supply of soda ash weakened. Manufacturers are actively shipping; The downstream performance in terms of demand is average, with narrow fluctuations in the glass market and slow consumption of inventory by enterprises. There is insufficient support for soda ash, and some purchases are mainly seeking lower prices. The market trading atmosphere is poor, and soda ash prices are mainly weak. On August 29th, the price of light soda ash in East China was reduced by 30 yuan/ton, with a range of 1100-1400 yuan/ton; The price of light soda ash in central China remains at 1130-1300 yuan/ton.
According to the commodity analysis system of Shengyi Society, the downstream glass market has risen narrowly. From August 25th to 29th, the price of glass increased from 13.83 yuan/square meter to 13.88 yuan/square meter, an increase of 0.36%. The production line of the glass market is running smoothly, with increased inventory in enterprises and average downstream consumption. There is limited replenishment upon entering the market. As the traditional peak season approaches, some enterprises have slightly increased their quotations, and the glass price market remains weak.
Future forecast: Currently, the price of soda ash is running weakly and steadily, and the mentality of industry players is mainly wait-and-see. Downstream demand has not yet rebounded, and soda ash companies continue to have weak shipments. The fundamental supply-demand contradiction persists, and it is expected that the soda ash market will run weakly in the later stage. Specific attention should be paid to downstream follow-up situations.

This week, the magnesium market experienced a brief and slight consolidation before gradually recovering, but overall prices have slightly decreased. The market supply and demand relationship is balanced, and the overall price remains stable.
Supply and demand side
In terms of supply, in the magnesium smelting industry, due to the current low inventory of enterprises, when magnesium prices experience a certain degree of decline, enterprises adopt different market response strategies. Among them, some companies choose to follow the market and ship in small quantities at current lower market prices to recoup funds or maintain market participation; On the other hand, some companies adhere to a pricing strategy based on optimistic expectations of future market trends or cost control considerations, choosing to stop shipping to avoid low-priced sales. The differentiation of this market behavior has led to significant resistance in the downward trend of magnesium prices, making it difficult to sustain the decline. At the same time, with the gradual increase in the number of market purchases, the supporting role of the demand side has become apparent, driving the rapid recovery of magnesium prices.
In terms of demand, the downstream market experienced a relatively concentrated procurement period last week, and the number of orders placed this week has decreased. The market trading atmosphere is slightly quiet, but as the weekend approaches, the market trading situation has rebounded.
Raw material end
Recently, the market has shown that coal prices have remained relatively stable, while orchid charcoal prices have slightly increased, silicon iron prices have remained stable, and overall costs have slightly decreased.
comprehensive analysis
During this year’s overseas summer break, the market continued to show a stable to strong trend, with prices gradually recovering to a relatively reasonable range and overall fluctuations being relatively small. This phenomenon indicates that the supply and demand pattern of the market has undergone fundamental changes, and the demand scale of the domestic market is sufficient to support the current market situation. Based on this, it is expected that the market will continue to maintain a stable tone and maintain a strong operating trend in the future.
