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!

Dear Client, To keep pace with the rapid development of the magnesium metal industry and the growing need for supply-demand pattern analysis, our company has deeply optimized the data model based on the SMM Magnesium Database and is now systematically upgrading and adjusting the data standards and historical data related to magnesium metal in China. The details are as follows: I. Data Standard Upgrades and Data Revision Notes Background of Adjustments With the rapid growth in demand for magnesium alloys in the downstream sector of magnesium metal, the market landscape is evolving rapidly. For instance, technological iterations in die-casting equipment, differences in the penetration rate of thick and thin magnesium alloy die-cast parts, and recycling rates, among other multidimensional factors, have a significant impact on the production of recycled magnesium. To promptly address the industry's need for supply-demand pattern analysis amid its rapid development, adjustments have been made to the data collection standards for "recycled magnesium production," "primary magnesium production," and "total magnesium metal demand," with historical data also being revised. Previous data collection did not account for the supply of recycled magnesium, which could lead to significant deviations in supply estimates. As the SMM Magnesium Database becomes increasingly comprehensive and detailed, a more robust model has been established. Adjustment Details - Data Source Upgrade: Upgraded from a single primary magnesium market supply and demand dataset to the establishment of a dual supply-demand model for magnesium metal, encompassing both primary and recycled sources. - Revision Scope: Historical data from January 1, 2023, to the present (including retrospective revisions and future forecasts). Effective Date From October 30, 2025 SMM Information & Technology Co., Ltd. SMM Magnesium Research Team Jiao Jiani 021-20707954 October 27, 2025

In recent years, with the steady development of Malaysia's manufacturing and stainless steel processing industries, the local stainless steel scrap recycling system has become increasingly mature. The number of recyclers, sorting facilities, and reprocessing enterprises has grown significantly, and the proportion of locally recycled scrap in the circular economy continues to rise, providing strong support for regional stainless steel raw material supply. Meanwhile, Malaysia has become one of the main sources of stainless steel scrap imported by India. According to trade statistics, Malaysia exported approximately 107,000 tons of stainless steel scrap to India in 2024, reflecting strong linkage between the two countries in raw material recycling. Large domestic recycling and processing enterprises possess advanced sorting and reprocessing capabilities, enabling them to classify and process regional scrap and steadily supply high-quality materials to major Asian stainless steel producers in Japan, South Korea, and elsewhere. Against the backdrop of a diversified regional raw material structure and growing value of recycled resources, Malaysia's domestic ex-works stainless steel scrap prices have become an important reference indicator for the Southeast Asian stainless steel industry.
