1. Glass Report 1.1 Report Industry Investment Rating No relevant information provided. 1.2 Core Viewpoints - In September, the spot glass market operated steadily. Traditional peak - season demand warmed up slightly, and inventory decreased. The policy signal of banning new capacity boosted market sentiment, leading to price hikes and increased sales - to - production ratios.

In October, supply fluctuations are expected to be limited, and the market will focus on capacity elimination policies. It is recommended to operate with caution [12][13]. 1.3 Summary by Directory 1.3.1 Monthly Assessment and Strategy Recommendation - As of September 30, 2025, the spot price of float glass was 1220 yuan/ton, up 70 yuan/ton month - on - month; the closing price of the main glass contract was 1228 yuan/ton, up 29 yuan/ton month - on - month; the basis was - 8 yuan/ton, up 41 yuan/ton week - on - week. - The weekly average profit of producing float glass with natural gas was - 151.27 yuan/ton, up 13.57 yuan/ton; with coal was 95.07 yuan/ton, up 1.04 yuan/ton; with petroleum coke was 61.37 yuan/ton, up 20 yuan/ton. - The weekly output of national float glass was 112.42 tons, up 0.3 tons month - on - month, with 225 production lines in operation (unchanged), and the operating rate was 76.01%. - The downstream deep - processing orders of float glass were 10.5 tons, up 0.10 days; the operating rate of Low - e glass was 47.10%, down 1.00%.
