Report Information - Report Title: Glass and Soda Ash Weekly Report - Report Date: July 20, 2025 - Analyst: Zhang Chi from Guotai Junan Futures Research Institute - Investment Advisory Qualification Number: Z0011243 [1] Glass Market Supply - As of July 17, 2025, there were 296 domestic glass production lines after excluding zombie lines, with 223 in operation and 73 cold - repaired and shut down. The daily output of national float glass was 157,800 tons, a decrease of 0.38% compared to July 10. The daily loss of float glass was 42,200 tons, a 1.44% increase from the previous period, and the weekly loss was 239,000 tons, a 0.05% decrease from the previous period [2]. - In 2025, the total daily melting volume of cold - repaired lines was 10,530 tons/day, and the total daily melting volume of ignited lines was 11,510 tons/day. The potential new ignition lines had a total daily melting volume of 14,000 tons/day, and the potential old - line复产 had a total daily melting volume of 8,130 tons. The potential cold - repair lines had a total daily melting volume of 6,900 tons/day [11][12][13] - Short - term production reduction space is limited, but if demand is poor in the third quarter, there may be a certain scale of production reduction in the fourth quarter. The current in - operation capacity is about 158,000 tons/day, with a peak capacity of 178,000 tons/day in 2021 and a recent low - level capacity of 148,000 - 150,000 tons/day [17]. Demand - As of July 15, 2025, the average order days of national deep - processing sample enterprises was 9.3 days, a 2.1% decrease from the previous period and a 7.0% decrease year - on - year. In mid - July, most deep - processing enterprises reported that orders basically maintained the previous level, with no sign of improvement in demand, and the current profit level was still low, with a few reporting a continued decline in orders [2]. Inventory - As of July 17, 2025, the total inventory of national float glass sample enterprises was 64.939 million heavy boxes, a decrease of 2.163 million heavy boxes from the previous period, a 3.22% decrease, and a 0.29% increase year - on - year. The inventory days were 27.9 days, a decrease of 1.0 day from the previous period. The inventory in most regions decreased slightly [3][37]. Price and Profit - This week's transactions were basically stable, with most prices unchanged. Some prices in Shahe increased by 10 yuan/ton. The price in Shahe was about 1,130 - 1,180 yuan/ton, in central China's Hubei region it was about 1,050 - 1,100 yuan/ton (some manufacturers increased prices by 20 yuan/ton), and in the eastern Jiangsu and Zhejiang regions, the price of some large manufacturers was about 1,220 - 1,360 yuan/ton [20][23]. - The futures rebounded, the basis was weak, and the monthly spread was weak. The profit of petroleum coke was about - 50 yuan/ton, and the profit of natural gas and coal fuel was about - 183 - 108 yuan/ton [26][31]. Strategy - Unilateral: Oscillating strongly, with upper pressure at 1,180 - 1,200 and lower support at 1,000 - 1,030. - Inter - period: Buy 01 and sell 09. - Inter - variety: Buy glass and sell soda ash [4]. Photovoltaic Glass Market Price and Profit - Prices declined, recent order follow - up decreased slightly, glass manufacturers' shipments were average, and inventory continued to increase. The mainstream order price of 2.0mm coated panels was 10 - 11 yuan/square meter, a 2.33% decrease from the previous period, and the decline rate increased by 0.06 percentage points compared to last week. The mainstream order price of 3.2mm coated panels was 18 - 19 yuan/square meter, remaining flat compared to the previous period [46][48]. Capacity and Inventory - As the market weakens, it may enter a production reduction cycle again. As of early July, the actual capacity was about 94,000 tons/day. The sample inventory days were about 35.64 days, a 2.94% increase from the previous period, and the increase rate narrowed by 3.86 percentage points compared to last week [50][51][55]. Soda Ash Market Supply - This week, soda ash enterprises' equipment gradually resumed and increased production. The domestic soda ash output was 733,200 tons, a 3.42% increase from the previous week, and the capacity utilization rate was 84.10%, a 2.78% increase from the previous week. Some enterprises were in the process of maintenance or production reduction, and some were expected to have maintenance in the future [6][59]. Demand - The profits of downstream float glass processes have gradually improved, especially the profit of coal - gas production is relatively optimistic, but the production of petroleum coke and natural gas is still in a loss state. Photovoltaic glass profit is at a low level. Float glass and photovoltaic glass are generally cautious in purchasing soda ash, and demand has not expanded significantly [6]. Inventory - This period, the inventory of soda ash enterprises was 1.9056 million tons, a 2.26% increase from the previous period and a 111.85% increase year - on - year. The inventory of light soda ash was 783,000 tons, a decrease of 830,000 tons from the previous period, and the inventory of heavy soda ash was 1.1226 million tons, an increase of 505,000 tons from the previous period [7]. Price and Profit - The nominal prices in Shahe and Hubei were about 1,200 - 1,300 yuan/ton. This week's prices changed little. The basis was weak, and the monthly spread was under pressure. The profit of the joint - alkali method in East China (excluding Shandong) was - 39.5 yuan/ton, and the profit of the ammonia - alkali method in North China was - 82 yuan/ton [70][73][81]. Strategy - Unilateral: Oscillating weakly, with upper pressure at 1,320 - 1,340 and lower support at 1,220 and 1,150. - Inter - period: Buy 01 and sell 09. - Inter - variety: Buy glass and sell soda ash [8]
