Dear Users: Hello: To ensure data consistency with the source and respond to customer feedback, we have expanded the unit of zinc-related import and export data in the non-ferrous metals database to the smallest level. Core changes: Units such as "10,000 mt" and "mt" have been changed to "kg". The specific details are announced as follows: I. Reasons for Adjustment Due to the need for country-specific breakdown of imports and exports, the unit has been adjusted to the smallest value To better serve customers, SMM has expanded the import and export data related to the zinc industry chain to include all countries. This will result in the previously set units such as "mt" and "10,000 mt" being unable to match data from all countries. Therefore, SMM has changed the unit to the smallest value. II. Adjustment Details III. Effective Date of Adjustment This adjustment will take effect on August 8, 2025 SMM (Shanghai Metals Market) August 4, 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
