Dear Industry Peers, Imported manganese ore is a key raw material for manufacturing products such as silicomanganese alloy and ferromanganese alloy, with high-quality manganese ore being particularly favored by the market. Australian manganese ore is a mainstream and high-frequency oxide ore globally, serving as an important reference standard for global manganese ore pricing, and its price fluctuations directly impact the cost chain of global manganese-based alloys. Tianjin Port and Qinzhou Port are the main unloading ports for imported manganese ore in China. Equipped with complete storage facilities, these two ports feature high single-vessel unloading efficiency and large manganese ore reserve capacity. The formed complementary pattern of "Tianjin in the north and Qinzhou in the south" has enhanced China's bargaining power in global manganese ore trade. Prices at Tianjin Port (north) and Qinzhou Port (south) serve as benchmarks for global manganese ore pricing, which are referenced by both domestic and foreign ore merchants. To actively respond to market changes, meet the urgent demand of users for understanding the prices of Australian Mn42% manganese ore at Tianjin Port and Qinzhou Port, and improve the transparency of market information, SMM has decided: Commencing December 31, 2025, SMM will officially launch two new price: SMM Mn Ore, Australia Block 42%, In-whs-Tianjin Port, Yuan/ton-degree SMM Mn Ore, Australia Block 42%, In-whs-Qinzhou Port, Yuan/ton-degree Details of this price point are as follows: Description: SMM Mn Ore, Australia Block 42%, In-whs-Tianjin Port, Yuan/ton-degree Quality: Mn 42% Quantity: Min 100 tonnes Definition: EX-warehouse-Tianjin Port Brand Listing: South 32,etc Timing: Prompt Unit: Yuan/ton-degree Payment Terms: Cash on same day, other payment terms normalized Pulication: Daily, by 11am Beijing Time (i.e., before 4:00 AM London Summer Time before 3:00 AM London Winter Time) Description: SMM Mn Ore, Australia Block 42%, In-whs-Qinzhou Port, Yuan/ton-degree Quality: Mn 42% Quantity: Min 100 tonnes Definition: EX-warehouse-Qinzhou Port Brand Listing: South 32,etc Timing: Prompt Unit: Yuan/ton-degree Payment Terms: Cash on same day, other payment terms normalized Pulication: Daily, by 11am Beijing Time (i.e., before 4:00 AM London Summer Time before 3:00 AM London Winter Time) SMM Nickel Industry Research Department December 26, 2025

Dear users, On August 29, 2025, the State Administration for Market Regulation and the Standardization Administration of China jointly issued the "Secondary Lead Ingot (GB/T 21181-2025)" (hereinafter referred to as the "new national standard"), which will officially take effect on March 1, 2026. Compared to the "Secondary Lead and Lead Alloy Ingot (GB/T 21181-2017)" (hereinafter referred to as the "old national standard"), the new national standard revised the scope. It changed from "This standard applies to secondary lead and its alloy ingots produced by smelting and processing using lead-containing scrap as raw material, mainly used in batteries, alloys, chemical industry, and other fields" to "This document applies to secondary lead ingots produced by pyrometallurgical smelting and processing using waste lead-acid batteries and recycled lead and lead alloy materials as raw materials, mainly used in lead-acid batteries, alloys, chemical industry, and other fields." Regarding secondary lead grades, the ZSPb99.994 and ZSPb99.992 secondary lead ingot grades were deleted the ZSPb99.990, ZSPb99.986, and ZSPb99.983 secondary lead ingot grades were added. Details are as follows: With the development and changes in the secondary lead industry, the actual production and use of secondary lead in the market in recent years have already diverged significantly from the old national standard. In addition to changes in the main element lead content, the bismuth (Bi) content has also undergone substantial changes. According to SMM's understanding of major producers and users of secondary lead, the distribution by bismuth content usage is as follows: enterprises using bismuth content ≤0.008% account for about 15% those using ≤0.012% account for about 60% and those using ≤0.015% account for about 25%. Furthermore, based on its price assessment methodology, SMM solicited market suggestions on the specifications for the secondary refined lead price. Market feedback recommended that the price collection standard for SMM's secondary refined lead price reference the new national standard for secondary lead, with grade ZSPb99.99 accounting for 24%, grade ZSPb99.986 for 66%, and grade ZSPb99.983 for 10%. Considering that the current actual usage in the secondary lead market covers the three grades specified in the new national standard for secondary lead, SMM will define the specifications for the national and regional prices of secondary refined lead as ZSPb99.983-99.99%, based on real market transaction conditions. The new standard will be officially implemented from January 1, 2026, serving as the reference standard for SMM's price assessments. During this period, SMM will continue to collect suggestions and feedback from all parties, closely follow changes in the lead industry chain market, and identify and optimize SMM prices to better serve the industry! For any questions regarding prices, please contact lead analyst Wenming Xia at 021-51666839. SMM Information & Technology Co., Ltd. Lead and Zinc Research Division December 25, 2025
