Dear Users, Greetings! Thank you for your continued attention and support for Shanghai Metals Market (SMM)! The SMM Crude Lead Delivered Duty Paid Port Price has now been officially launched. The price assessment methodology is described as follows. I. SMM Price Assessment Methodology General Provisions Shanghai Metals Market (hereinafter referred to as SMM) is a fully independent third-party service provider. SMM does not participate in any substantive transactions but maintains close communication with buyers or sellers in its capacity as a market observer or organizer, and provides relevant services to the market. Through communication and exchanges with industry professionals, SMM continuously develops, reviews, and revises its methodology, adopting the most common product specifications, trade terms, and trade conditions in the industry, and giving equal attention to all normal transactions that meet specification standards. SMM reserves the right to exclude from its price assessments any price data or information deemed less reliable or unrepresentative. SMM reports daily spot transaction prices in China's spot market, commonly referred to as SMM prices. SMM prices are generated strictly in accordance with defined methodologies. SMM has methodology definitions for all metal product prices it reports. All methodologies and definitions are published on SMM's official website (www.smm.cn) so that all market participants can understand the processes and standards of SMM price reporting. The SMM price assessment methodology serves as the basis and foundation for the generation of SMM prices. To reflect the actual conditions of the spot market, SMM will make necessary revisions to its price assessment methodology. Any changes to the price assessment methodology will be published on SMM's official website at least 30 days in advance. Any questions or suggestions regarding SMM prices or the price assessment methodology may be directed to SMM client services as published on the website. This document specifies the standards and management methods for the formulation of the SMM Crude Lead Delivered Duty Paid Port Price. The purpose of establishing this standard is to create a transparent and verifiable SMM pricing mechanism and to provide market participants with an important pricing benchmark. II. Formation of the SMM Crude Lead Delivered Duty Paid Port Price 2.1. Definition The SMM Crude Lead Delivered Duty Paid Port Price is an indicative price formed and published by SMM in accordance with this methodology, which can be used by both parties to a transaction as a reference for the settlement of imported recycled crude lead spot trades. This price reflects: the duty-paid self pick-up price of imported recycled crude lead at major seaports on each business day in China's spot market; major seaports include Shanghai, Ningbo, Guangzhou, etc.; lead content ≥98%, with defined antimony and tin content (tin 0.1–0.25%; antimony 0.1–0.35%). 2.2. Introduction to Price Formation SMM collects data for evaluating imported secondary crude lead spot prices through price collection (i.e., collecting raw data information that meets SMM standards), including quotations from buyers and sellers for transactions not concluded on the previous day provided by price submitters (i.e., data providers), actual spot transaction prices, expected quotations or % change for imported secondary crude lead on the day, etc. The SMM crude lead CIF duty-paid price aims to guide the quotation range of the imported secondary crude lead market for the day. The data collection and evaluation (calculation) of the SMM crude lead CIF duty-paid price, as well as daily management, are carried out by the SMM secondary lead business team (consisting of three members: Position A, Position B, and a price manager). 2.3. Generation of Pricing Methodology SMM price collection personnel collect prices from price collection contacts at price submitters every day from 9:00 to 11:30 (each trading day, consistent with SHFE trading days) via telephone, QQ, and WeChat, gathering intended prices, transaction prices, and related data for imported secondary crude lead at China's major seaports (price data submitted after 11:30 will not be used as a basis for the day's price evaluation). All instant messaging content, email communications, and records of any face-to-face communications will be archived, and details of telephone communications will be summarized and entered into the database. All paper records must be signed by price collection personnel and retained permanently. SMM price analysts collect price data in accordance with price collection standards, and combine the preliminary price data results with the corresponding market's spot conditions, futures conditions, policies, industry status, market transactions, supply and demand relationships, inventory levels, as well as other significant political, economic, and natural factors, to ultimately derive a preliminary raw dataset. SMM price analysts must comply with relevant SMM compliance policies when reporting to their supervisors any communications from market participants that are coerced or threatened, or any induced offers attempting to influence evaluation results. 2.4 Price Publication The SMM crude lead CIF duty-paid price is published at 11:40 Beijing time on each trading day on the SMM official website in both Chinese and English. (Excluding China's statutory holidays and weekends.) The deadline for price collection is 11:30 AM, and the 10-minute period between 10:30 and 10:40 is used for data verification and evaluation to calculate the final published secondary lead spot price. SMM encourages price submitters not to wait until the final deadline to submit data, in order to ensure that SMM price analysts have sufficient time to verify the data before incorporating it into the valuation process. The release time may also be affected by various emergencies and force majeure factors, such as power outages and natural disasters. If such situations occur, SMM will make every effort to publicly inform the market of the delayed price release time as early as possible. Prices published by SMM are available to any client who has subscribed to SMM services. Prices published by SMM are copyright-protected and may not be distributed or used for commercial gain by any third party that has not entered into an explicit agreement with SMM. III. Methodology Changes All markets evolve, and SMM has a responsibility to ensure that its market-specific methodologies evolve in tandem. Therefore, based on industry feedback, SMM will periodically conduct internal reviews of the appropriateness of its methodologies and make modifications to all substantive but non-urgent potential issues. SMM will follow a formal external consultation process before publishing significant changes, providing a notice period of at least 28 days and inviting industry participants to comment, unless special circumstances, particularly force majeure (natural disasters, wars, exchange bankruptcies, etc.), necessitate a shortened notice period. SMM is committed to carefully reviewing all comments submitted regarding methodology changes, but in certain cases, it may be necessary to make changes to the methodology against the wishes of some market participants. In addition, SMM has a formal methodology consultation process. We are fully aware of the importance of price information to industry development and will therefore continue to invest resources to ensure that the guidance prices we publish maintain a high level of accuracy and timeliness. We also welcome valuable opinions and suggestions from users to work together with us in promoting the healthy and sustainable development of the lead alloy market. Best regards!

In-depth Interpretation & Review of Indonesia’s Aluminum Industry Policies Centering on bauxite and extending to the entire aluminum industrial chain, the Indonesian government has rolled out a series of policies focusing on three core dimensions: volume control, pricing mechanisms, and tax rates. These measures aim to gradually improve the regulatory system, standardize industrial development, and accelerate the transformation from raw ore exports to integrated domestic downstream aluminum production. This article sorts out relevant policy details and their impacts in detail as follows: I. Volume Control: Strengthen Quota Management & Full-process Digital Supervision to Achieve Precise Supply Regulation ① Bauxite Quota: RKAB Approval Cycle Adjusted to Enhance Government Regulation Capacity Regulation Capacity Indonesia standardizes the full-process mining and sales of bauxite across all mines via the RKAB (Mining Work Plan and Budget) system. The core policy adjustment focuses on optimizing the approval cycle, mainly based on Permen ESDM No.17/2025 issued by the Ministry of Energy and Mineral Resources (ESDM) on October 3, 2025. New regulations shall be officially implemented starting from 2026: Approval Cycle Revision: The RKAB approval model for all mining enterprises is changed from once every three years to annual application and annual approval. Mines must submit RKAB applications for the next year between October 1 and November 15 each year, with all approvals completed by the end of the year to guarantee orderly production in the subsequent year. Transition & Application Timeline: In Q1 2026, if the new annual RKAB quota is still under review, the original 2026 quota can be adopted temporarily. Quota adjustment applications for the current year shall be submitted by the end of July annually, while the centralized submission window for the next year’s quota is set from October 1 to November 15, forming a dual management model of annual approval plus dynamic adjustment. Scenario Analysis & Policy Impacts Original Three-Year Approval Model: Unable to accurately forecast market demand for the next two years, this model easily triggers supply-demand mismatches and overall oversupply, putting downward pressure on bauxite prices. It also limits flexible government regulation, resulting in significant policy lag as quotas cannot be adjusted timely in response to market changes. New Annual Approval Model: The government gains stronger annual regulatory authority to dynamically adjust total annual quotas based on international bauxite prices, global supply-demand fundamentals and domestic smelting demand, improving price stability. Meanwhile, it strengthens fiscal revenue guarantees and regulatory efficiency through a more transparent and streamlined approval process, reduces rent-seeking behaviors, and advances compliant industrial development. ② SIMBARA System: Full-chain Digital Supervision to Curb Illegal Mineral Trading In accordance with Perpres 94/2025 (Presidential Regulation No.94/2025), the SIMBARA system (Inter-Ministerial Mineral and Coal Information System) officially incorporated bauxite into its regulatory scope in 2025, establishing a full-process digital supervision system covering operations from mines to end users. Through the SIMBARA official portal, the Indonesian government tracks real-time bauxite sales data and monitors the entire transportation chain from mining to downstream processing, including inter-island logistics, with precise linkage to mining quotas. It covers all key links: mining sites, processing, transportation and exports. The implementation of this system not only aligns Indonesian bauxite mining with global industry standards, but also effectively restrains irregular activities such as illegal mining, child labor and environmental damage, promoting green and compliant development of the sector. All bauxite mines are required to submit full-operation documents via the SIMBARA system, including production reports, inventory statements and raw material procurement records, for joint reviews by four core authorities: the Ministry of Energy and Mineral Resources, Ministry of Industry, Ministry of Trade, and Ministry of Transportation. The mechanism realizes data sharing, joint supervision and full traceability. II. Tax Rate: Standardize Billing Rules & Optimize Tax Burden Structure ① Indonesia’s Bauxite Tax Framework: Fixed Fee + Ad Valorem Royalty The country’s bauxite taxation policy adopts a dual structure of fixed administrative fees and floating royalties, clarifying differentiated charging rules for various mining rights. Combined with revisions to the HPM pricing mechanism, the overall tax burden structure has been optimized. Fixed Fee: Paid in a lump sum on an annual basis Core Formula: Fixed Fee = Mining Concession Area × Corresponding Unit Rate Floating Royalty: Charged per sales transaction and highly linked to commodity prices Core Formula: Royalty = Sales Volume × Transaction Price × Applicable Rate Transaction bonuses and premiums shall be included in invoice amounts for unified tax calculation; Pricing benchmark confirmation: If the premium is negative (actual transaction price benchmark price), tax calculation shall adopt HPM plus premium. Calculation Example Assume HPM = USD 44/ton, bauxite indicators: Al₂O₃=49%, Reactive Silica=2%. Actual transaction price: USD 35/ton (Premium = -9 USD/ton), Bonus = USD 1/ton, net transaction price = USD 36/ton. Given the negative premium, royalty is calculated based on HPM: Royalty = 44 USD/ton × 7% (standard bauxite royalty rate) = 3.08 USD/ton. ② Revised HPM Pricing Mechanism Effective April 15, 2026 (Kepmen ESDM No. 144/2026) Core Revisions: Pricing unit adjusted: Dry Metric Ton (DMT) → Wet Metric Ton (WMT) New deduction factor: Reactive Silica (R-SiO₂) New moisture adjustment clause added Regulators require bauxite enterprises to cooperate with inspection institutions and add key indicators including alumina content, reactive silica and moisture content to official Certificate of Analysis (COA). Data updates on the e-PNBP and MVP systems are also mandated to ensure accurate royalty calculation. The revised HPM mechanism lowers benchmark prices and overall royalty costs, reducing comprehensive bauxite mining costs and accelerating mine shipments as well as downstream industrial integration layouts. ③ Optimized HPM Pricing Cycle: Higher Flexibility to Align with Global Markets The pricing cycle has been shortened to reduce policy lag and better reflect LME aluminum price fluctuations. Old Rules (Before March 1, 2025): Monthly single HPM release. The pricing reference window covered the 20th of the month before last to the 19th of the previous month, with a pricing lag of around 45 days, failing to reflect timely international price changes. New Rules (Effective March 1, 2025): Semi-monthly HPM releases on the 1st and 15th of each month. 1st Issue (1st of each month): Calculated by average LME aluminum spot prices from the 5th to the 25th of the prior month (21-day cycle, 5-day lag); 2nd Issue (15th of each month): Calculated by average LME aluminum spot prices from the 26th of the prior month to the 4th of the current month (10-day cycle, 5-day lag). Core Benefits Improved market sensitivity: The shortened cycle enables HPM to reflect real-time LME movements, strengthens linkage with global pricing, and avoids price distortion caused by long-term average calculations; Optimized revenue management: The government can adjust domestic mineral benchmark prices more precisely in response to global aluminum volatility, balancing reasonable profit margins for mining enterprises and stable national tax revenue. III. Pricing Policy: Abolish HPM Floor Price to Boost Market Circulation & Downstream Development A landmark adjustment in Indonesia’s bauxite price regulation is the cancellation of the mandatory HPM minimum settlement price, implemented in phases to balance fiscal revenue and market vitality. Old Regulation (Kepmen ESDM No.72/2025): Bauxite transaction prices were strictly prohibited from falling below HPM. This rule triggered supply-demand imbalance, sluggish ore sales and suspended shipments by major miners, severely restricting normal market circulation. New Regulation (Kepmen ESDM No.268/2025): Signed on August 8, 2025, and officially implemented in late August 2025. The core revision abolishes the HPM floor price and allows transactions below benchmark prices. Nevertheless, taxes and royalties are still calculated based on standard HPM values to shield national fiscal revenue from price declines. Core Advantages of the Revised Policy Government Perspective: HPM-based tax collection guarantees stable fiscal revenue independent of market fluctuations. Loosened price controls revitalize trading activity, resolve the supply glut dilemma, support mine capacity expansion and local employment, and secure long-term industrial stability. Industrial Perspective: Discounted transactions ease inventory pressure for miners and accelerate capital turnover. Lower raw material procurement costs reduce production expenses for domestic smelters, incentivize downstream capacity commissioning, and help Indonesia achieve its 2040 strategic goal of full aluminum chain integration.

It has become a consensus that domestic demand for new energy vehicles will be under periodic pressure in 2026. However, the industry has not lost its growth momentum but is shifting from past expansion driven by pricing and policy to a growth model supported by products, structural optimization, and markets outside China. At the same time, the rise on the cost side is squeezing profit margins, making the issue of "growing but not profiting" increasingly visible.

Recently, the Shanghai Municipal National Development and Reform Commission (NDRC) issued a notice on the *Key Work Arrangements for Carbon Peaking, Carbon Neutrality, Energy Conservation and Emission Reduction in Shanghai for 2026*. The document stated that Shanghai would promote the diversified development of local renewable energy sources such as wind and solar power, with the city adding 600,000 kW of new PV installations. Two batches of standalone ESS power station projects would be advanced. The results of competitive bidding on mechanism-based electricity prices for new energy incremental projects would be publicly announced. Huangpu District would be organized to carry out the national carbon peaking pilot program. Chongming District would be supported in steadily advancing the national pilot program for ecological product value realization mechanisms. The *Shanghai Action Plan for Accelerating Green and Low-Carbon Transformation (2024–2027)* would be implemented, promoting the deployment of 15 key application scenarios for green and low-carbon transformation. The construction of national-level zero-carbon industrial parks would be supported, and a number of municipal-level zero-carbon industrial parks would be developed.

On April 16 (Thursday), a document showed that Codelco and global miner Anglo American plan to separately submit environmental study reports to regulators for their proposed shared Andina-Los Bronces copper mine in Chile, using what they called an "unprecedented" dual-track model to streamline the approval process. The document showed that the two companies plan to submit two essentially identical applications in December for a copper mine to be jointly operated by both parties. Chile is currently the world's largest copper-producing country. Against the backdrop of an anticipated tightening in global copper supply, this model could serve as a blueprint for other major miners looking to share infrastructure and operations to boost production. The model would also allow Codelco and Anglo American to move faster and reduce risks. Codelco and Anglo American finalised this cooperation agreement in September 2025, planning to increase annual copper production by approximately 120,000 mt from 2030 to 2051, creating at least $5 billion in pre-tax value. ***"Mirror" Applications*** In areas where operations will overlap, the two companies proposed adopting identical environmental protection measures for each miner. A presentation document showed that they considered a single application submission legally unfeasible, as the Chilean constitution requires Codelco to retain ownership of its mining concessions. The two companies had also considered submitting three applications: one from each miner to extend the life of their respective mines, and a third from a joint entity responsible for operating the shared project. They ruled out this option, as it would require the enterprises to relinquish their existing open-pit mine environmental protection permits to make way for the merged mine. This "dual-track structure" also makes it possible for the two mines to resume independent operations in the future. ***On-Site Operations*** The documents detailed the plan to create a single mine site from the existing operations. Anglo American's Los Bronces mine is adjacent to Codelco's Andina mine. The two companies' plans showed that the rock barrier between them will also be mined, forming a single operating pit while keeping the project essentially within the existing footprint of the mines. A document showed that ore extracted from the shared mine site will be alternately sent to the Los Bronces and Andina processing plants, while waste rock will be dumped in each company's respective waste rock piles. To operate the two mines as an integrated system, modifications to waste rock piles, tailings facilities, pipelines, and supporting infrastructure are still required. The two companies stated that shared infrastructure can avoid redundant construction, reduce freshwater consumption, and alleviate pressure on the surrounding environment. ***Risks of a "Shared" Mine*** The two companies also identified significant risks, such as the need for close coordination with regulators, which could put pressure on Chile's already slow environmental review system. They emphasised that the project has "a very high level of public attention" and that there is a risk that environmentalists and affected communities may argue that the two reviews obscure the scale of the impacts. The Los Bronces mine has been accused for years of impacting air quality, water use, and glaciers in the high Andes region where it is located. Although Codelco and Anglo American believe the dual-track approach can reduce the risk of impacts being underestimated, they also acknowledged that it could lead to duplication of environmental protection management measures.
