We have updated the organization of our Other Minor Metals section for better navigation, grouping price points by specific metal categories.

Dear users, Hello! In recent years, the cesium and rubidium industry chain has undergone continuous changes. During SMM's ongoing research to improve the cesium and rubidium industry chain, it was found that there is a lack of market liquidity for cesium and rubidium metals despite quoted prices, and there are significant price spreads in market quotations. To reduce transaction risks and costs for upstream and downstream clients, after a period of deliberation and market consultation, SMM has decided to adapt to market development needs and suspend the timely updates of cesium and rubidium metal prices. The specific adjustments are as follows: 1. Suspension: "Cesium metal (Cs≥99.5%)", with the suspension date set for August 15, 2025 (working day). 2. Suspension: "Rubidium metal (Rb≥99.5%)", with the suspension date set for August 15, 2025 (working day). The above-mentioned price points that have ceased updates will be removed from the website quotation window. However, historical prices and these price points will still be retained in the database. If clients have any needs related to historical data, they can contact the SMM Minor Metal Research Team. SMM Minor Metal Research Team Jia Jiani Contact Information: jiaojiani@smm.cn August 11, 2025
