"Tin" Leads the Future: Industrial Transformation and Value Reshaping in the New Cycle Conference Background Currently, the global tin industry is at a historic turning point, with traditional cyclical logic completely disrupted and strategic value fully highlighted. The tin market in 2026 is exhibiting an unprecedentedly complex landscape and profound transformation: 1. Profound Restructuring of the Supply-Demand Pattern, Unprecedented Enhancement of Strategic Attributes Global tin reserves have a static reserve-to-production ratio of just 14 years, underscoring growing scarcity. The supply side faces "threefold pressure": repeated setbacks in Myanmar’s production resumption, continuously tightening policies in Indonesia, and elevated geopolitical risk in the DRC. Resource constraints have become the new normal. Meanwhile, the demand structure is undergoing a fundamental shift, making tin a strategic resource that bridges traditional manufacturing and the digital future. 2. A Historic Breakthrough in the Price System, Industry Ecology Facing a Remaking In early 2026, the SHFE tin price broke through 470,000 yuan/mt, hitting a record high. This price breakthrough not only reflects supply-demand imbalance but also marks a revaluation of the tin industry. Traditional trade models, risk management systems, and supply chain collaboration methods urgently require breakthrough innovations. 3. Technology-Driven and Green Transition Foster a New Symbiotic Ecosystem Digital and intelligent technologies are deeply empowering the tin industry chain. The global green transition calls for the tin industry to upgrade toward a low-carbon, circular economy, with recycled tin recovery and green smelting processes becoming the necessary path. All links in the industry chain must shift from competition to collaboration, building an open, resilient, and innovative symbiotic system. Against this backdrop, August 19-21, 2026 in Changsha, Hunan , the 2026 SMM (16th) Tin Industry Chain Conference will bring together global industry elites to jointly explore.

From H2 2025 to early 2026, the copper industry underwent profound structural shifts. China's smelting capacity continued to be released, reliance on imported raw materials deepened, and the supply of copper concentrates remained persistently tight. Driven by monetary policy changes, geopolitical conflicts, production cuts at mines outside China, and accelerated industry consolidation, copper prices repeatedly hit new highs. The industry shifted from a tight balance to a structural deficit, further strengthening copper's role as a strategic resource. Hereby, SMM joins hands with Qixian Hongda Refractory Co., Ltd. to cordially invite enterprises across copper mining, copper smelting, and related third-party equipment and consumables sectors to co-produce the . This initiative aims to gather high-quality industry resources and create an authoritative industry platform, helping enterprises enhance their industry influence and jointly promoting quality-driven industry development.
