I. General Principles of SMM Price Methodology Shanghai Metals Market (hereinafter referred to as SMM) is a fully independent third-party service provider and does not participate in any substantive transactions. Instead, it acts as a market observer or organizer, maintaining close communication with buyers and sellers in transactions and providing relevant services to the market. SMM continuously develops, reviews, and revises its methodology through communication with industry professionals, adopting the most common product specifications, trade terms, and conditions in the industry, while giving equal importance to normal transactions that meet standard specifications. SMM reserves the right to exclude any price information deemed unreliable or unrepresentative from its pricing assessments. SMM publishes daily metal spot prices (or price indices, including the Chinese market, markets outside China, and global markets), commonly referred to as SMM prices. SMM has established corresponding methodologies for all published SMM prices (all of which are available for reference on SMM’s official website, www.smm.cn ). These methodologies specify the methods and procedures for generating and publishing SMM prices, which are strictly adhered to. To align with the actual conditions of the spot market, SMM may make necessary revisions to the SMM price methodology, which will be announced on the SMM official website before formal implementation. For any questions or suggestions regarding SMM prices or their methodologies, please contact SMM customer service (contact information can be found on the SMM official website, www.smm.cn ).

For all substantive but non-urgent potential revisions, SMM will follow a formal external consultation process. Major changes will be announced with a notice period of at least 28 days, inviting industry comments, unless special circumstances, particularly force majeure (natural disasters, war, exchange bankruptcy, etc.), necessitate a shorter notice period. SMM is committed to carefully reviewing all comments on proposed methodology changes. However, in some cases, it may be necessary to make changes to the methodology against the wishes of some market participants. Additionally, SMM has a formal methodology consultation process.

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!
