"Tin" Leads the Future: Industrial Transformation and Value Reshaping in a New Cycle **Conference Background** Currently, the global tin industry stands at a historic turning point, where traditional cyclical logic has been fundamentally disrupted and strategic value has become fully prominent. The tin market in 2026 presents an unprecedented complex pattern and profound transformation: **I. Deep Restructuring of the Supply-Demand Pattern with Unprecedented Elevation of Strategic Attributes** The global static reserve-to-production ratio of tin resources is only 14 years, with scarcity becoming increasingly prominent. The supply side faces "triple pressures": repeated setbacks in Myanmar's production resumptions, continued tightening of Indonesian policies, and elevated geopolitical risks in the DRC — resource constraints have become the new normal. Meanwhile, the demand structure has undergone a fundamental shift, and tin has become a strategic resource connecting traditional manufacturing with the digital future. **II. Price System Breaking Historical Records with the Industrial Ecosystem Facing Reshaping** In early 2026, SHFE tin prices broke through 470,000 yuan/mt, hitting a record high. This price breakthrough is not only a reflection of supply-demand imbalance but also a hallmark of value reassessment for the tin industry. Traditional trade models, risk management systems, and supply chain collaboration approaches all urgently require innovative breakthroughs. **III. Technology-Driven and Green Transformation Fostering a New Symbiotic Ecosystem** Digital and intelligent technologies are deeply empowering the tin industry chain. The global green transformation requires the tin industry to upgrade toward low-carbonisation and circular economy models, making recycled tin recovery and green smelting processes an inevitable path. All segments of the industry chain must shift from competition to collaboration, building an open, resilient, and innovative symbiotic system. Against this backdrop, the 2026 SMM (16th) Tin Industry Chain Conference , to be held on August 19-21 in Changsha, Hunan , will bring together global industry elites for in-depth discussions.

[SMM Tungsten Daily Review: Guangdong Tungsten Enterprise Announced Long-Term Contract Prices, Tungsten Market's Stop Falling and Stabilize Trend Confirmed] SMM May 25: Today, tungsten market sentiment eased, downstream purchasing increased, and transactions in APT, powder, and other segments recovered. A tungsten mine in Hunan auctioned tungsten concentrates with a grade of approximately 12-21%, moisture content of approximately 12%, an estimated 430 mt in physical content, or about 100 standard tonnes (65%WO3 basis). The auction was successfully concluded, with transaction prices concentrated at over 370,000-380,000 yuan/standard tonne (65%WO3 basis). The decline in spot order transaction prices for tungsten concentrates slowed down significantly, and the ore side basically consolidated at lows.

Supply-demand fundamentals of hot-rolled coil side, maintenance in early to mid-June will have limited impact and will drive hot-rolled coil supply to rebound. Demand is unlikely to deliver impressive performance against the backdrop of an overall off-season for steel consumption. SMM expects hot-rolled coil inventory to continue destocking in early to mid-June, with the pace of inventory decline expected to slow down in late June, with a probability of inventory buildup. Supply-demand imbalance accumulation will be limited in early to mid-June. Attention should be paid to the subsequent impact from the raw material side and export order-taking conditions.

In April 2026, domestic lead prices overall moved sideways, with spot cargo and futures trends remaining relatively stable. According to SMM data, the average spot price of SMM #1 lead ingot in April was 16,525 yuan/mt, with prices operating steadily within the range during the month, rising first then declining. Futures market, SHFE lead contract prices were generally higher than spot prices……

[SMM Chrome Daily Review: Market Remained Stable with a Wait-and-See Attitude, Trading Stayed Mediocre] May 22, 2026: The ferrochrome and chrome ore market experienced minor fluctuations...

SMM May 25 News: Data Brief: As of Monday, May 25, SMM copper inventories in major regions nationwide increased by 2,300 mt WoW to 245,200 mt, up 105,500 mt compared to the same period last year (139,700 mt). Specifically, imported sources in Shanghai increased somewhat, though domestic arrivals contracted simultaneously. Combined with copper prices remaining at elevated levels, downstream enterprises showed notably weakened willingness to purchase. Warehouse inflows and outflows over the weekend maintained a steady pace, and regional inventory levels remained largely unchanged. In Jiangsu, influenced by the rising trend in copper prices, downstream procurement demand was generally weak, but local domestic copper arrivals pulled back somewhat, leading to slight destocking in the region. In Guangdong, the end-use consumer market performed sluggishly, becoming the core factor behind continuous inventory accumulation, with inventory levels continuing to climb. Market outlook: Supply side, short-term import arrivals decreased somewhat, while domestic source arrivals increased, gradually easing the overall tight supply situation. Demand side, downstream enterprises generally adopted a wait-and-see attitude amid elevated prices, with market demand remaining soft. According to the survey, the copper cathode rod operating rate is expected to decline to 61.61% this week, down 0.36 percentage points WoW. Considering overall supply-demand performance, supply is marginally loosening while demand remains weak, and social inventory is highly likely to continue its inventory buildup trend in the short term.

[SMM Stainless Steel Daily Review] SS Futures Strengthened, Stainless Steel Spot Prices Remained Firm with Inquiries and Transactions Boosted SMM, May 25: SS futures continued to hold up well. Driven by the overall strength of non-ferrous metal futures and SHFE nickel, SS futures rose in tandem. As of the midday close, the most-traded SS contract was quoted at 14,805 yuan/mt. In the spot market, buoyed by the slight uptick in futures, spot quotes remained firm, with both market inquiries and transaction activity improving. However, the current macro environment still carried significant uncertainties, steel mill production schedules stayed high, and the traditional off-season was gradually approaching, intensifying industry participants' concerns about the market outlook. The most-traded SS contract held up well. At 10:15 AM, SS2605 was quoted at 14,860 yuan/mt, up 60 yuan/mt from the previous trading day. Spot premiums for 304/2B in the Wuxi area were in the range of 310-710 yuan/mt. In the spot market, the average price of cold-rolled 201/2B coils in Wuxi remained stable with a downward bias; for cold-rolled trimmed-edge 304/2B coils, Wuxi remained stable and Foshan's average price held steady; cold-rolled 316L/2B coils in the Wuxi area fell 50 yuan/mt; hot-rolled 316L/NO.1 coils in Wuxi dropped 175 yuan/mt; cold-rolled 430/2B coils in both Wuxi and Foshan remained stable. This week, the stainless steel market saw both futures and spot prices fluctuate within a stable range. Futures movements were mainly driven by industry news and expectations, with limited overall fluctuations. Market sentiment was divided — traders held a cautious stance, but downstream end-user just-in-time procurement remained resilient. Combined with traders' active shipments, market supply continued to be absorbed, with the overall situation showing...

[SMM Morning Meeting Minutes: China's Tin Market Overall Shows a Pattern of Weak Supply and Demand; Consumption End Has Limited Acceptance of High Prices]

The International Copper Study Group (ICSG) released preliminary data on global copper supply and demand for March 2026 in its monthly bulletin published in May 2026. Preliminary data indicated that global copper mine production in Q1 2026 was basically flat, with copper concentrates production declining by 1.1%, offset by a 3.3% increase in solvent extraction-electrodeposition (SX-EW) production. Although global mine production benefited from additional output driven by capacity ramp-up of projects in several countries, significant declines in copper concentrates production in Chile, the DRC, and Indonesia offset global growth. In Indonesia, copper concentrates production at the Grasberg mine fell by 42%, as the severe mud inflow incident that occurred in September last year continued to affect the mine's production. Chile's mine production declined by 5.8%, with increased production at the Collahuasi and Quebrada Blanca mines offset by production cuts at the Spence, El Teniente, Escondida, and Los Pelambres mines. The DRC's mine production is estimated to have grown by only 0.5%: SX-EW production increased by approximately 10%, but was partially offset by a 36% decline in copper concentrates production due to reduced output at the Kamoa mine (affected by the 2025 earthquake event). In Peru, copper mine production grew by 3.3%, primarily driven by increased production at the Antamina, Las Bambas, and Antapaccay mines, which more than offset production declines at Southern Peru Copper, Quellaveco, and Marcobre. Mongolia's copper concentrates production is estimated to have grown by approximately 36%, benefiting from the capacity ramp-up of the Oyu Tolgoi underground project. Preliminary data indicated that global copper cathode production grew by approximately 4.5% in Q1 2026, with primary copper (electrolysis and ore electrodeposition) production increasing by 3.8% and secondary copper (from scrap) production increasing by 7.6%. China and the DRC, which currently account for approximately 60% of global production, saw their combined production increase by an estimated 9% (China 8.8%, DRC 10%). Excluding these two countries, global copper cathode production declined by approximately 1.4%. Chile's copper cathode production fell by 11.7%, with copper cathode (from concentrates) production declining by 24% due to smelter operational constraints and maintenance, and electrodeposition copper production declining by 5.7%. Production in Asia (excluding China) is estimated to have declined by 4%, mainly due to production decreases in Japan, Indonesia, and the Philippines. India's production is estimated to have grown by 25%, benefiting from improved capacity utilization rates and the capacity ramp-up of the Adani smelter. Global secondary refined copper production (from scrap) increased by 7.6%, mainly driven by growth in China. Preliminary data indicated that global apparent refined copper usage grew by 0.8% in Q1 2026. Although global usage excluding China was estimated to have grown by 1.7%, China's apparent demand (excluding bonded warehouse/unreported inventory changes) was estimated to be basically flat, affected by a 40% decline in China's net imports of copper cathode. China currently accounts for approximately 58% of total global refined copper usage. The preliminary global refined copper supply-demand balance indicated an oversupply of 396,000 mt in Q1 2026. In compiling the global market balance, ICSG used China's apparent demand calculation method, which does not account for changes in unreported inventories. However, to facilitate global market analysis, an adjustment item has been added to the attached tables — "Global refined copper balance adjusted for Chinese bonded warehouse inventory changes" — which adjusts the global refined copper balance based on the average bonded warehouse inventory change estimates from two Chinese copper market consultancies. In Q1 2026, the global refined copper balance based on China's apparent usage (excluding bonded warehouse/unreported inventory changes) showed a preliminary oversupply of approximately 396,000 mt, compared with an oversupply of approximately 135,000 mt in the same period of 2025. The global refined copper balance adjusted for estimated changes in Chinese bonded warehouse inventories showed a market oversupply of approximately 386,000 mt. Copper Prices and Inventories: Based on the average estimates from two independent consultancies, Chinese bonded warehouse inventories were estimated to have decreased by approximately 10,000 mt from the end of 2025 levels during the first three months of 2026. As of the end of April 2026, copper inventories at major metal exchanges (LME, COMEX, SHFE) totaled 1,148,760 mt, the highest level since January 2003. Inventories increased by 404,648 mt, or 55%, from the end of December 2025, with LME up 253,350 mt, Shanghai Futures Exchange up 46,683 mt, and COMEX up 104,615 mt. The LME spot copper average price in April was $12,891.38 per mt, up 3% from the March average price of $12,498.98 per mt. The 2026 copper price high and low were $14,097 per mt (May 13) and $11,826 per mt (March 19), respectively, with a year-to-date average price of $12,947.22 per mt, up 30% from the 2025 average price.

Nickel Ore " Indonesia Officially Issues Presidential Decree Requiring Designated State-Owned Enterprises to Monopolize Strategic Resource Exports Starting This June " 1. Price Dynamics and HMA Revisions The Indonesian nickel ore price remained stable this week. The Ministry of Energy and Mineral Resources (ESDM) has officially released the Nickel Mineral Benchmark Price (HMA) for the second half of May 2026. Nickel HMA: $18,849.3/dmt (up $1047.15 or 5.88% from $17,802.14 in early May). Cobalt HMA: $55,854/dmt. Iron Ore HMA: $1.58/dmt. Chrome Ore HMA: $6.37/dmt. Current port-delivered prices for 1.6% grade pyrometallurgical ore (saprolite) stand at $77.8-80.8/wmt. In contrast, 1.2% grade hydrometallurgical ore (limonite) is priced at approximately $28-33/wm.. 2. Supply-Demand Fundamentals and Weather Impacts For pyrometallurgical ore, unseasonal, abnormally heavy rainfall in the Central and South Sulawesi regions (Morowali and surrounding mining areas) has severely disrupted land transportation and barge transshipment. A series of micro-earthquakes (reaching up to magnitude M$1.9$) that occurred near Morowali between May 17 and 18 further exacerbated this impact. The combination of highly saturated soil moisture and minor crustal tremors has significantly increased the risk of landslides and slope instability, forcing mines to slow down their extraction and heavy-truck transportation pace for safety reasons. Therefore, even though the approval rate of regulatory quotas (RKAB) has reached approximately 90%, the spot supply of high-grade ore remains tight. To cope with exorbitant costs and tight supply, smelters are actively adopting cost-reduction strategies. These include blending low-grade ores into raw materials to lower the overall grade, promoting a unified premium pricing model of "HPM + USD $7–$10/wmt," and implementing standardized benchmarks for the chemical specifications of pyrometallurgical ore (Cobalt 0.05%, Iron 20%, Chrome 1%) to eliminate additional premiums for individual ore components. Meanwhile, the hydrometallurgical nickel ore market continues to suffer a severe disconnect from official pricing. The price of low-grade hydrometallurgical ore is under severe pressure and has completely failed to follow the upward trend of the new HPM. This price depression is primarily driven by the dual contraction of smelter operating rates and immediate raw material demand, with the core trigger being a potential production cut in Mixed Hydroxide Precipitate (MHP) caused by a sulfuric acid supply shortage in May. Against a backdrop of relatively stable inventory levels, MHP refineries are leveraging this low-capacity operating environment to aggressively suppress procurement bids, causing hydrometallurgical ore prices to continue hovering at low levels. 3. SMM Internal Estimates The new pricing formula has led to increased price divergence and amplified volatility, particularly influenced by higher associated cobalt content in certain ores. SMM calculations show that the new HPM for 1.2% grade limonite is approximately $49.95, significantly higher than current market assessments. The new HPM for 1.6% grade saprolite is $70.83; the inclusion of higher cobalt content in the new formula has markedly amplified price fluctuations. While actual market transaction prices currently remain above this benchmark, the gap is steadily narrowing. 4. Regulatory Quotas (RKAB) and Market Outlook According to the ESDM, RKAB approvals for 2026 have reached approximately 90%. SMM statistics indicate that the total approved quota for Indonesian nickel ore stands at roughly 240 million wmt. The macroeconomic and policy focus of the market has recently shifted, primarily concentrating on the following two major export and contract regulatory policies: DSI's Full Takeover of the Export Mechanism: The Indonesian government has confirmed that starting January 1, 2027, DSI will fully take over the export business of coal, palm oil, and ferroalloys. This policy will facilitate a smooth transition of the export mechanism in two phases. Since ferroalloys (including ferronickel, NPI, etc.) fall within the scope of this takeover, the market is closely evaluating the impact of this transition period on the export logistics and compliance costs of Chinese-funded smelters. Crackdown on Under-Invoiced Long-Term Contracts: The Indonesian government emphasized that it will honor existing, valid long-term export contracts to maintain commercial credit. However, at the same time, the government will strictly investigate and punish long-term contracts suspected of "under-invoicing" (low-price customs declarations). It is reported that relevant Indonesian departments will soon hold consultations with major industry associations to ensure a smooth policy transition while plugging loopholes that lead to tax revenue losses from underpricing. Nickel Pig Iron " Supply-Demand Price Gap Widens; Short-Term Prices to Fluctuate within a Range " The average price of SMM 10-12% NPI average price fell by RMB 5.7 per nickel unit week-on-week to RMB 1140.3 per nickel unit (ex-works, tax included), while the Indonesia NPI FOB index dipped by USD 1.37 USD per nickel unit to an average of USD 146.52 per nickel unit. Downstream purchasing sentiment dropped even more visibly, intensifying the divide in market mindsets between buyers and sellers. On the supply side, existing NPI production cutbacks, coupled with recent disruptions from Indonesian export policy updates, have gradually tightened spot availability. Consequently, upstream producers are holding back cargo to defend their asking prices, generally keeping their offers firm. Sellers only slightly softened their quotes under the weight of weak futures markets, and their willingness to offload cargo at lower price levels remains low. This expectation of tighter market supply provides a solid floor for prices. On the demand side, pressure remains acute. The stainless steel market lacks upward momentum, forcing steel mills to adopt a highly cautious procurement stance centered strictly around hand-to-mouth restocking. Furthermore, as the price-to-performance advantage of stainless steel scrap expands, downstream buyers are pushing hard for discounts. Target buying prices remain heavily clustered between RMB 1,120 and 1,130/mtu, leaving a massive spread against upstream asking prices that makes reconciling the two sides very difficult. Market Outlook: While expectations of tightening supply will support spot prices, the weak futures market and competitive pricing from alternative raw materials will continue to cap upside gains. Accordingly, high-nickel pig iron prices are expected to exhibit a high-level, range-bound volatile trend next week.
