Dear User, Greetings! In recent years, the development of the secondary zinc industry has attracted significant attention however, the domestic supply of secondary zinc oxide has become increasingly tight. In contrast, Southeast Asia boasts abundant resources of secondary zinc oxide raw materials at relatively low prices, which has prompted many Chinese enterprises to establish production facilities in the region, with a considerable number choosing Vietnam. Meanwhile, amid growing uncertainties in international trade, an increasing number of companies are relocating their plants to Vietnam to achieve integrated procurement, production, and sales, gradually forming a market trend. To keep pace with the globalization of international trade and the market development of secondary zinc oxide both domestically and overseas, and to reflect the true price fluctuations of secondary zinc oxide in the global market, SMM plans to launch the CIF Imported Secondary Zinc Oxide Payable . The SMM CIF Imported Secondary Zinc Oxide Payable is an indicative price formed and published by SMM according to this methodology, which can be used by trading parties as a reference for settling secondary zinc oxide trades from Vietnam. This price reflects the mainstream price of the CIF Imported Secondary Zinc Oxide Payable​​​​​​​ for each month. The price will be officially launched on November 28, 2025, and historical prices can be viewed simultaneously on the SMM website (smm.cn). The price will be published by 18:00 on the last working day of each month. Price Definition: The mainstream transaction price of CIF Imported Secondary Zinc Oxide Payable in actual trades during the month. Going forward, SMM will continue to monitor changes in the zinc industry chain market, optimize SMM prices, and better serve the industry!

Respected Client, To keep pace with the rapid development of the magnesium industry and the evolving needs for supply-demand analysis, our company has optimized the data model based on the SMM Magnesium Database and is now systematically upgrading the data standards and historical data for magnesium-related metrics in China and globally. Details are as follows: Data Standards and Historical Data Adjustment Notice I. Background of Adjustment With the rapid growth of downstream magnesium alloy demand, the magnesium market landscape continues to evolve. Factors such as technological advancements in die-casting equipment, varying penetration rates of magnesium alloy die-cast parts across different thickness markets, and recycling utilization rates have significantly impacted recycled magnesium production. To better capture the effects of industry changes on supply-demand analysis, and in conjunction with SMM's further in-depth research on the proportion of magnesium added in aluminum industry processes—improving recycled magnesium recovery and utilization coefficients and revising historical data for "primary magnesium" and "magnesium powder" production—we are now adjusting and updating the following metrics in the balance sheet: "recycled magnesium supply," "primary magnesium supply," "magnesium consumption in aluminum products," and "magnesium powder production." II. Adjustment Details Data Points Revised: "Recycled Magnesium Supply," "Primary Magnesium Supply," "Magnesium Consumption in Aluminum Products," "Magnesium Powder Production." Revision Scope: Historical data from January 1, 2023, onward (including retrospective revisions and future forecasts). III.

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 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).
