Announcement on Adjusting the Quotation Frequency of Battery-Grade Lithium Fluoride Prices from Weekly to Daily

Dear Users: To ensure the consistency of data with the source and respond to customer feedback, we have expanded the unit of copper-related import and export data in the non-ferrous metals database to the smallest level. Core change: Units such as "10,000 mt" and "mt" have been changed to "kg". The specific matters are hereby 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 important copper-related import and export data to include all countries, which has made it impossible for the previously set units of "mt" and "10,000 mt" to match the data from all countries. Therefore, SMM has changed the unit to the smallest value. II. Adjustment Content III. Effective Date of Adjustment This adjustment will take effect on August 5, 2025 SMM August 1, 2025

To better serve industrial clients and stay closer to the market, SMM is adding 6 new scrap copper price assessments for Japan/US regions, officially launching on 16/1/2026. 1. New Price Points Copper Scrap - East Asia - Japan Millberry CIF China - Japan Millberry CIF China Taiwan - Japan Millberry CIF Korea Copper Scrap - America - United States Millberry CIF Japan - United States No.1 Copper Material CIF Japan - United States No.2 Copper Material CIF Japan 2. SMM Price Methodology General Principles Shanghai Metals Market (hereinafter referred to as "SMM") is a completely independent third-party service provider that does not participate in any actual transactions. Instead, SMM maintains close communication with buyers and sellers as a market observer or organizer and provides related services to the market. This document sets forth the standards for SMM's East Asia and US scrap copper price assessments. The purpose of establishing these standards is to create a transparent and verifiable SMM price formation mechanism. 3. Formation of SMM East Asia and US Scrap Copper Price Assessments 3.1 Significance of the Assessments In recent years, Japan and the United States have continued to play important roles in the global scrap copper trading system. Their export prices for berry copper and copper scrap hold strong reference value for major Asian consumer markets. Due to differences in origin quality structure, trade flows, and regional demand, actual transaction prices vary across different destinations. To more accurately reflect the true price levels of Japanese and US scrap copper in cross-regional circulation, reduce information asymmetry risks, and help upstream and downstream enterprises more reasonably evaluate procurement costs and formulate trading strategies, SMM plans to add price points including Japan Berry Copper CIF China, Japan Berry Copper CIF South Korea, Japan Berry Copper CIF Taiwan China, US Berry Copper CIF Japan, US No.1 Copper CIF Japan, and US No.2 Copper CIF Japan. These will be collected according to a unified methodology and publicly released to the market for industry reference. SMM price members will be able to access relevant historical price data simultaneously. 3.2 SMM East Asia and US Scrap Copper Price Assessment Methodology 3.2.1 Product Specifications and Standards Currently, scrap copper reference standards follow ISRI standards. If changes occur, SMM will revise accordingly based on actual circumstances. 3.2.2 Price Terms Prices are CIF indicative prices, expressed as a coefficient (%) unit. 3.2.3 Payment Terms Prices reflect payment conditions including TT or other conventional payment methods. 3.2.4 Quote Format and Timing Quoted prices are in range format, showing minimum and maximum prices. For example: Japan Millberry CIF China: 97.5%-98%. New price points will be assessed weekly. SMM will publish prices on the website front page at 3:30 PM on the last day of each working week. 3.2.5 Data Collection Method According to the data collection confirmation agreement, SMM price analysts will regularly collect price information from scrap copper industry contacts in Japan through telephone, WeChat, email, and other methods. This price information includes completed transaction prices and the most likely anticipated transaction prices expected by the enterprise. All instant messaging content and any face-to-face communication records will be archived telephone communication details will be recorded and entered into the database. SMM analysts must comply with the Compliance System when reporting to their supervisors any coerced or threatened communications from market participants, or any inducements attempting to influence assessments. After price publication, SMM will not make corrections or adjustments on that day. 3.2.6 Data Standardization Although SMM has standardized definitions for our prices, market transactions exist in various forms. Each transaction price is influenced by numerous factors, including order size, material brand, delivery time, payment terms, etc. SMM will comprehensively consider market quotes, bids, and transaction information and align them with our standards. We welcome more relevant enterprises along the industry chain to participate in and support SMM in better serving scrap copper industry-related enterprises. For any questions, please contact us.
