2、 Market analysis
According to the Commodity Analysis System of Shengyi Society, the soda ash market experienced a weak downward trend in September. On the supply side, the utilization rate of soda ash production capacity continues to rise, and market inventory continues to accumulate; In terms of demand, downstream traditional peak season orders have increased, but there has been little change in the production of the glass market, which has limited actual consumption of soda ash. The soda ash market has a general destocking, with strong supply and weak demand, and insufficient upward momentum for enterprises. As a result, soda ash prices have been weakly adjusted during the month.
As of September 29, 2025, the mainstream market price of light soda ash in East China is around 1100-1400 yuan/ton, a decrease of 10 yuan/ton compared to the previous month; The mainstream price of light soda ash in Central China is around 1130-1300 yuan/ton, which remains stable compared to the previous period; The mainstream price of light soda ash in North China is around 1200-1270 yuan/ton, a decrease of 30 yuan/ton compared to the previous period.
On the demand side: According to the commodity analysis system of Shengyi Society, glass prices have shown a strong upward trend this month, with the average glass market price rising from 13.88 yuan/square meter to 15.43 yuan/square meter, an overall increase of 11.17%. The glass production line started smoothly within the month, with little overall change in supply; The demand for downstream peak season has increased, with smooth shipments from enterprises and obvious glass destocking. In the first half of the year, glass prices fluctuated strongly. On the 24th, the glass industry held a symposium, and market news boosted glass prices, with manufacturers’ inventory remaining stable and the glass market operating strongly.
Market forecast: In the near future, the operating rate of soda ash will remain high, and inventory pressure on enterprises still exists. Although the downstream trend is strong, most of the purchases in the market are based on demand, and the demand support is insufficient. There is a significant oversupply in the market. It is expected that the soda ash price will weaken and consolidate in October, depending on the follow-up situation in the downstream.
