"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.

Persistent weakness in downstream demand dragged the tungsten market lower. As of May 19, the average price of wolframite concentrates (≥65%) was quoted at 445,500 yuan/standard tonne (65%WO3 basis). The current price has not only completely erased all gains accumulated within the year but also pulled back from the year-end 2025 price. Moreover, in just over two months, the average price has fallen 57.59% from its intra-year historical high. End-users have adopted a cautious purchasing stance, with weak demand transmitting upstream level by level, continuously exerting significant downward pressure on raw material prices. Under such circumstances, how will tungsten prices perform going forward? Wolframite Concentrates Continue to Decline, with All Intra-Year Gains Fully Retraced According to SMM quotations, on May 19, the quotation range for wolframite concentrates (≥65%) was 445,000–446,000 yuan/standard tonne (65%WO3 basis), with a market average price of 445,500 yuan/standard tonne (65%WO3 basis), down 3.26% from the previous trading day. In a horizontal comparison, the current average price pulled back 8,000 yuan/standard tonne (65%WO3 basis) from the average of 453,500 yuan/standard tonne (65%WO3 basis) on December 31, 2025, with all previously accumulated gains within the year fully retraced. Looking at the intra-year price trend, the current price has significantly departed from its highs. Compared to the intra-year historical average high of 1,050,500 yuan/standard tonne (65%WO3 basis) recorded on March 16 this year, the average price of wolframite concentrates has cumulatively plunged 605,000 yuan/standard tonne (65%WO3 basis) in just over two months, a cumulative decline of 57.59%, representing a highly significant pullback. Outlook Overall, there are currently no substantive positive factors underpinning the market. Downstream mainstream consumers such as cemented carbide and machining enterprises have adopted a conservative purchasing mindset, generally adhering to a strategy of "purchasing as needed and strictly controlling inventory," with overall end-use demand remaining persistently weak. Sluggish demand has directly dragged down upstream smelting-stage demand for products such as APT and tungsten powder, with operational pressure transmitting upstream level by level, continuously suppressing tungsten concentrates raw material prices. Even if mining controls remain stringent going forward and the commissioning progress of low-grade tungsten mines falls short of market expectations, the support from the supply side remains limited and is unlikely to offset the downward pressure brought by weak end-use demand. In the short term, the market lacks sufficient momentum to support a strong price rebound. Tungsten product prices are expected to move sideways amid the interplay between weak demand and low raw material costs. Close attention should be paid to subsequent long-term contract pricing by major tungsten enterprises for guidance on tungsten prices. From a medium and long-term perspective, China's primary tungsten ore mining scale and production are still expected to continue their YoY declining trend. However, during the previous tungsten price surge cycle, the terminal tungsten consumption structure underwent deep optimization, with tungsten consumption in low-value-added sectors gradually being cleared; coupled with the cemented carbide industry's continuous quality upgrades, extended tool service life, and accelerated transition toward high-end products, multiple factors have resulted in China's actual tungsten consumption volume falling short of earlier market expectations. Against this backdrop, the tungsten industry's supply-demand pattern has undergone a fundamental shift—from the previous logic of price increases driven by mine-side supply contraction, it has officially transitioned to a new pattern of "demand-led, structure-priced, cost-supported, and expectations-driven."

On May 20, 2026, Indonesian President Prabowo Subianto announced during a plenary session of the National Congress that the government has officially signed a groundbreaking regulation targeting the governance of natural resource exports. This bold policy framework will establish a dedicated state-managed natural resource export agency, executing exports through State-Owned Enterprises (BUMN) acting as government-designated single exporters. According to local media disclosures and presentation slides shown during the session, this centralized mechanism will initially apply to palm oil, coal, and ferroalloys ( paduan besi ) . Under this system, direct private export transactions will be phased out, forcing overseas buyers and Indonesian producers to route contracts, logistics, and payments entirely through state-appointed BUMN nodes. 1. The Two-Phase Implementation Timeline Based on the official policy schematic diagrams disclosed on-site, the transition to a centralized BUMN-led export model will occur in two distinct regulatory phases: Phase 1 (Transition) Time : June 1, 2026 - August 31, 2026 Mechanics : Private enterprises continue to manage some internal administrative and logistics steps. However, all existing and new import-export transactions with overseas buyers must begin a step-by-step migration to BUMN entities. Phase 2 (Full Monopsony) Time : September 1, 2026, Onward Mechanics : Complete takeover. All transaction flows, sales contracts, export declarations, customs clearance, shipping arrangements, and the collection of export earnings (DHE) will be fully managed or led by designated BUMN. 2. Deep Structural Intervention: Pre- to Post-Clearance This regulatory mechanism does not simply install a government "rubber stamp." Instead, it represents a fundamental reallocation of the entire export trade chain, deeply embedding BUMN across three key logistics and financial phases: [Pre-Clearance] ──> [Clearance] ──> [Post-Clearance] (Contracts & Docs) (Customs & Loading) (Payment & FX DHE) Pre-Clearance (Contract & Goods Preparation): This covers verifying legality, IUP mining licenses, export restrictions ( Lartas ) compliance, sales contract drafting, finalizing payment terms, commercial invoicing, and vessel chartering/cabin bookings. Clearance (Customs & Physical Shipment): Includes filing export declarations (PEB), managing customs system approvals, cargo transport from smelter warehouses to port terminals, loading shipments, and issuing Bills of Lading (B/L). Post-Clearance (Documentation & Capital Flow): BUMN will act as the principal intermediary, dispatching trade documents (B/L, Commercial Invoice, Packing List, Certificate of Origin/COO) to the buyer's issuing bank and managing the repatriation of export proceeds (DHE) under strict domestic banking provisions. 3. The Billion-Dollar Question: Will NPI and FeNi be Classified as "Ferroalloys"? For the global stainless steel and electric vehicle battery supply chains, the immediate focal point is how Indonesia defines the scope of "ferroalloy" ( paduan besi ). Market consensus strongly suggests that the "ferroalloys" under discussion are highly likely targeting Nickel Pig Iron (NPI), which represents a massive trade flow of approximately 11.5 million tons of Indonesian NPI exports in 2025. However, because the official, legally binding regulation "signed" by the government has not yet been formally released to the public, further clarification is needed to verify the exact scope of affected materials. Crucially, the leaked written draft of the regulation does not actually mention "ferroalloys" at all. The term "ferroalloy" ( paduan besi ) was only verbally highlighted and presented by President Prabowo during the House of Representatives Plenary Session (Rapat Paripurna DPR) on Wednesday (20/5). According to the leaked draft text, the actual written scope of the law is structured as follows: CHAPTER II: DETERMINATION OF STRATEGIC NATURAL RESOURCE COMMODITIES Article 2 (1) Strategic Natural Resource Commodities subject to export governance include: a. coal; b. palm oil; and c. other strategic natural resource commodities. (2) The Government may amend the Strategic Natural Resource Commodities as referred to in paragraph (1) letters a and b, and establish other Strategic Natural Resource Commodities as referred to in letter c through a coordinated meeting ( rapat koordinasi ) led by: a. the minister responsible for synchronization, coordination, and control of ministerial affairs in the field of the economy ( Coordinating Minister for Economic Affairs / Menko Perekonomian ); or b. the minister responsible for synchronization, coordination, and control of ministerial affairs in the field of food ( Coordinating Minister for Food / Menko Pangan ), attended by relevant ministers/heads of non-ministerial agencies. This clause reveals a crucial legal framework: any expansion of the export control list to designate NPI, FeNi, or related ferronickel alloys under "other strategic commodities" is strictly required to be determined through a formal coordinated meeting ( rapat koordinasi ) led by either the Coordinating Minister for Economic Affairs or the Coordinating Minister for Food. Because the written regulation itself is silent on "ferroalloys," the legal scope of the policy has not been fixed yet . Until this high-level inter-ministerial coordination meeting ( rapat koordinasi ) takes place and issues a definitive annex list with matching HS codes, the practical impact on NPI trade remains pending official confirmation. Should nickel-iron intermediates formally fall under the BUMN single-exporter mandate after this meeting, SMM foresees four critical structural disruptions: I. Erosion of Direct Negotiation Flexibility Currently, Indonesian NPI is sold through a highly flexible ecosystem of steel mills, global trading desks, independent brokers, and back-to-back supply contracts. Forcing these contracts to route through a single state exporter compresses the operational room for direct price discovery, spot volume locking, and rapid high-frequency reselling. II. Absolute Export Price Transparency By funneling all sales contracts, shipping invoices, and foreign exchange collection (DHE) through state-owned channels, the Indonesian government will gain real-time, absolute transparency over actual transaction prices. This complements Indonesia's ongoing tightening of domestic mining benchmarks (HPM), the annual RKAB quota system, and the strict requirement for export proceeds to be held in domestic bank accounts. III. Disintermediation of Traders and Brokers In-transit or port-stored nickel-iron inventories have historically served as highly liquid financial assets for brokers and traders who leverage transfer orders and back-to-back contracts. Standardizing all contract entities and payment channels under BUMN will squeeze the margins of non-producing traders, rendering physical spot market quotes highly rigid. IV. Export Execution Delays Migrating long-term off-take agreements to BUMN templates will trigger significant friction during the Phase 1 transition. SMM expects delays stemming from contract re-signings, banking channel adjustments, letter of credit (L/C) re-issuances, and initial administrative coordination at port customs, temporarily disrupting short-term port-arrival schedules. 4. Market and Price Impact Analysis (If NPI were to be Involved) Short-Term Sentiment vs. Medium-Term Realities Short-Term (Sentiment-Driven): The direct impact on physical NPI shipping volumes returning to China will remain limited during the initial transition window, as private exporters continue to assist with logistics. However, given tight domestic nickel ore supplies, production cuts at several RKEF plants, and already declining NPI shipments, the market will likely digest this announcement as a fresh supply-side threat, driving up bullish sentiment. Medium-Term (Structural Shifts): If NPI is formally included in the HS code list, Chinese stainless steel mills will face centralized Indonesian state sellers. This will result in stronger payment scrutiny, fewer options for non-standard flexible transactions, and the virtual elimination of low-cost, off-market FOB deals. Transaction Costs vs. Production Costs Unlike mining-end disruptions such as rising HPM benchmarks, declining laterite ore grades, or restricted RKAB quotas, this export centralization policy does not directly raise the physical smelting cost of NPI. Instead, it functions as a tax on transaction efficiency, increasing compliance burdens, administrative delays, and state oversight on pricing. SMM concludes that the impact of this policy is an increase in "transaction-side friction" rather than raw production costs, which will ultimately support sellers' intentions to hold prices firm and reinforce the price rigidity of high-nickel pig iron. 5. SMM Outlook Indonesia’s new export regulation signals that its resource nationalism is successfully extending its reach beyond the mine gate and tax office, directly into the global sales and trading arena. However, the key takeaway is that nothing is legally set in stone for the nickel industry yet. Because the written regulation currently leaves the door open under "other strategic commodities," and the word "ferroalloy" was only delivered verbally by the President on Wednesday (20/5), the entire framework remains unfixed. The critical indicator for the nickel chain over the coming weeks is whether the upcoming inter-ministerial rapat koordinasi formally adopts the HS codes for NPI and FeNi into the final regulatory annex.
