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

Dear Industry Peers, Imported manganese ore is a key raw material for manufacturing products such as silicomanganese alloy and ferromanganese alloy, with high-quality manganese ore being particularly favored by the market. Australian manganese ore is a mainstream and high-frequency oxide ore globally, serving as an important reference standard for global manganese ore pricing, and its price fluctuations directly impact the cost chain of global manganese-based alloys. Tianjin Port and Qinzhou Port are the main unloading ports for imported manganese ore in China. Equipped with complete storage facilities, these two ports feature high single-vessel unloading efficiency and large manganese ore reserve capacity. The formed complementary pattern of "Tianjin in the north and Qinzhou in the south" has enhanced China's bargaining power in global manganese ore trade. Prices at Tianjin Port (north) and Qinzhou Port (south) serve as benchmarks for global manganese ore pricing, which are referenced by both domestic and foreign ore merchants. To actively respond to market changes, meet the urgent demand of users for understanding the prices of Australian Mn42% manganese ore at Tianjin Port and Qinzhou Port, and improve the transparency of market information, SMM has decided: Commencing December 31, 2025, SMM will officially launch two new price: SMM Mn Ore, Australia Block 42%, In-whs-Tianjin Port, Yuan/ton-degree SMM Mn Ore, Australia Block 42%, In-whs-Qinzhou Port, Yuan/ton-degree Details of this price point are as follows: Description: SMM Mn Ore, Australia Block 42%, In-whs-Tianjin Port, Yuan/ton-degree Quality: Mn 42% Quantity: Min 100 tonnes Definition: EX-warehouse-Tianjin Port Brand Listing: South 32,etc Timing: Prompt Unit: Yuan/ton-degree Payment Terms: Cash on same day, other payment terms normalized Pulication: Daily, by 11am Beijing Time (i.e., before 4:00 AM London Summer Time before 3:00 AM London Winter Time) Description: SMM Mn Ore, Australia Block 42%, In-whs-Qinzhou Port, Yuan/ton-degree Quality: Mn 42% Quantity: Min 100 tonnes Definition: EX-warehouse-Qinzhou Port Brand Listing: South 32,etc Timing: Prompt Unit: Yuan/ton-degree Payment Terms: Cash on same day, other payment terms normalized Pulication: Daily, by 11am Beijing Time (i.e., before 4:00 AM London Summer Time before 3:00 AM London Winter Time) SMM Nickel Industry Research Department December 26, 2025
