SMM, Dec. 19, 2025:

The SMM weekly operating rate for secondary lead smelters in four provinces was 41.61% from Dec. 12 to Dec. 18, 2025, down 3.75 percentage points WoW. This week, many areas in east and north China implemented environmental protection-related controls due to severe air pollution. Secondary lead smelters in Anhui, a major producing region, severely cut production, causing the regional operating rate to drop 11.88 percentage points MoM. If the controls are lifted this weekend, production will resume to normal levels. The operating rates in Henan and Jiangsu remained flat WoW. A secondary lead smelter in Inner Mongolia briefly suspended production last week due to equipment part replacement but resumed normal operations this week, leading to a rebound in the regional operating rate. However, local smelters indicated that pressure from tight raw material supply on production persists. In summary, if smelters in Anhui resume normal production this weekend, the secondary lead operating rate is expected to rebound next week. However, frequent winter haze may lead to environmental protection-related controls, posing potential limitations on secondary lead smelters' production. Additionally, the retirement volume of waste lead-acid batteries from EVs softened, and raw material supply pressure remains a major factor affecting the secondary lead operating rate.

Guangxi Typhoon Has No Immediate Impact on Local Zinc Smelter Production

Affected by the 10th typhoon this year, "Maysak," many areas in Guangxi were hit by continuous heavy rainfall. Places including Fangchenggang, Qinzhou, Guigang, and Nanning experienced rainstorms to heavy rainstorms, with locally extreme rainstorms, causing severe waterlogging in some urban areas, surging river levels, and risks at multiple reservoirs. Based on this, SMM conducted a survey of zinc smelters in Guangxi and learned that production has not been affected yet, but severe port waterlogging has hindered the transportation of raw materials and finished products. It is also learned that in July, some lead-zinc mines in Guangxi have already suspended production for maintenance due to the impact of the rainy season.

Analysis of Maintenance and Production Cuts at Secondary Lead Enterprises in June–July

Recently, China's lead prices have continued to weaken. Secondary smelters have been broadly trapped in a dual predicament of production losses and a shortage of scrap battery raw materials. SMM's statistics on production cuts and resumption plans at secondary lead enterprises across the country in June–July clearly reflect the current pressure on the industry.
