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 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! For any inquiries regarding the price, please contact Zinc Analyst Hua Lin at 021-20707885 hualin@smm.cn. SMM Information & Technology Co., Ltd. Zinc Research Team November 21, 2025
