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.

Driven by intensifying global competition for energy and mineral resources, the reshaping of refined copper trade flows, and the resurgence of U.S. manufacturing policies, the U.S. market has once again emerged as a key pricing anchor in international refined copper distribution. According to SMM research, U.S. annual refined copper consumption is estimated at 1.6–1.8 million metric tons, with the Midwest — home to a high concentration of copper-intensive manufacturing — serving as the country’s largest region for copper processing, delivery, and end-use. Over time, this region has developed a mature spot trading market under the DDP (Delivered Duty Paid) delivery model. Since 2025, global copper trade dynamics have shifted significantly. The U.S. has become increasingly reliant on imports from Latin America, Europe, and Africa. With frequent tariff policy changes, a surge in COMEX stock levels, more active trade tenders, and renewed long-term contract negotiations, the Midwest DDP premium has become an essential reference point for industrial trade and arbitrage models across the supply chain. Against this backdrop, Shanghai Metals Market (SMM) will officially launch the Copper grade 1 cathode premium, ddp Midwest US on February 1, 2026. Quoted in US cents per pound (¢/lb), this premium will be based on representative spot DDP trades in the U.S. Midwest. The price reflects a weighted average considering warehouse transfer costs, regional logistics fees, trading activity levels, and brand preferences — offering an objective and actionable settlement benchmark for market participants. The price will be updated daily and published on both the SMM official website. Historical curves and price analytics will also be made available. This price release aims to enhance pricing transparency across the refined copper supply chain and provide more granular tools for trade execution, long-term contract negotiations, and production planning — supporting more efficient and accurate price discovery in the global market. Key specifications of the SMM U.S. Midwest DDP Refined Copper Premium are as follows:

To better serve industrial clients and more closely align with the market, SMM has added a weekly price for 1.8mm Tin-Plated Copper Rod Premium (Electroplating), Ex-works China, VAT included, yuan/tonne, which will be officially launched on the SMM website (smm.cn) on December 19, 2025. 1. SMM 1.8mm Tin-Plated Copper Rod Premium (Electroplating), Ex-works China, VAT included, yuan/tonne Methodology 1.1 SMM Price Assessment Methodology General Provisions Shanghai Metals Market (SMM) is a fully independent third-party service organization that does not participate in any actual transactions. Instead, it maintains close communication with buyers or sellers in the market as an observer or organizer and provides relevant services to the market. SMM continuously develops, reviews, and revises its methodology through communication with industry professionals, adopting the most common product specifications, trade terms, and trade conditions in the industry. Equal importance is given to normal transactions that meet the standard specifications. SMM reserves the right to exclude any price information deemed less reliable or unrepresentative from its price assessments. SMM publishes daily spot metal prices (or price indices, including those for the Chinese market, markets outside China, and global markets), commonly referred to as SMM prices. For each published SMM price, a corresponding methodology is established (all of which are available for reference on SMM’s official website, www.smm.cn). The methodology specifies the methods and procedures for generating and publishing SMM prices, and SMM strictly adheres to these guidelines when producing and releasing SMM prices. To align with the actual conditions of the spot market, SMM will make necessary revisions to the SMM price assessment methodology and announce these revisions on the official website www.smm.cn 28 days before their formal implementation. If you have any questions or suggestions regarding SMM prices or the methodology, please contact SMM customer service (contact information can be found on the official website www.smm.cn ). This document specifies the standards for formulating the weekly RC for 1.8mm Tin-Plated Copper Rod Premium (Electroplating), Ex-works China, VAT included, yuan/tonne. The purpose of establishing this standard by SMM is to create a transparent and verifiable mechanism for SMM price formation. The SMM Benchmark Management Committee also regularly reviews the methodology and its assessment and publication processes. This committee oversees SMM’s methodology and compilation procedures, ensuring that the prices or indices accurately reflect the objective conditions of the physical spot market for the relevant commodities. If the committee identifies any issues, it will promptly highlight them and propose external consultation and revisions to the ongoing methodology or processes, thereby improving the quality of SMM’s published prices or indices. The committee may only propose modifications to the methodology and procedures used for future price or index assessments it cannot alter already published prices or indices. 2. Formation of 8mm Tin-Plated Copper Rod Premium (Electroplating), Ex-works China, VAT included, yuan/tonne. 2.1 Significance of the Price Assessment Current copper rod industry faces increasingly prominent overcapacity issues, with low capacity utilization rates. The market for ordinary power-grade rods suffers from homogenized competition, processing fees are caught in internal competition, and profit margins for most enterprises are severely compressed. Against this backdrop, the copper rod industry is gradually transitioning toward high-quality development, enhancing product added value, expanding profit margins, and progressively addressing the structural imbalance of "excess low-end supply and insufficient high-end supply." Tin-plated copper rods, leveraging characteristics such as oxidation resistance, ease of welding, and strong stability due to the tin coating, meet the demands of high-end sectors like new energy vehicles and electronic devices. With the continuous expansion of emerging industries such as new energy and 5G communication, the tin-plated copper rod market holds broad prospects and will become a key direction for the transformation and upgrading of the copper processing industry. 2.2 SMM 1.8mm Tin-Plated Copper Rod Premium (Electroplating), Ex-works China, VAT included, yuan/tonne Price Assessment Methodology 2.2.1 Product Specifications and Standards Given the wide variety of tin-plated copper rod specifications, SMM adopts the 1.8mm diameter, which holds a relatively high market share, as the basis for quoting tin-plated copper rod processing fees, with reference to the standard GB/T3952-2016 Copper Rod for Electrical Purposes. 2.2.2 Price Terms Ex-works, China, 1.8mm Tin-Plated Copper Rod premium top on SMM 1# Copper Cathode 2.2.3 Payment Terms cash, other terms normalized. 2.2.4 Delivery Time Within 3 days. 2.2.5 Reference Transaction Volume Min 1 tones. 2.2.6 Delivery Location China 2.2.7 Price Release Time Weekly, by 11：30 am Beijing time, last working day of every week. 2.2.8 Processing Fee Format The reported processing fees are presented as a range, indicating the lowest and highest prices.
