From November of last year through the end of May this year, domestic spot tin prices climbed from 300,000 RMB/ton to 420,000 RMB/ton—a cumulative increase of 40% over six months—setting a new multi-year high for spot prices. The primary driving force behind this latest surge in tin prices is the explosive growth across the entire AI industry chain. As a critical solder material for advanced semiconductor packaging and server PCBs, tin has been dubbed the "Computing Power Metal" by the market. A single AI server consumes up to three times the amount of tin required by a traditional server; consequently, the continuous expansion of global computing infrastructure is generating a structural increase in tin demand. This trend, coupled with the global scarcity of mineral resources and persistent supply constraints in major overseas producing nations, has created a supply-demand mismatch that continues to bolster tin prices. In turn, this has triggered distinct shifts in the domestic spot market landscape, import-export dynamics, and the broader industry chain.
I. Domestic Spot Tin and Regional Price Trends (May 27 – June 3)
As of June 3, the benchmark tin price reported by SunSirs stood at 421,500 RMB/ton, maintaining its high-level trajectory while regional price quotes exhibited a distinct pattern of divergence.
In the East China (Shanghai) market, the mainstream trading range for #1 grade spot tin was 419,000–424,000 RMB/ton. With spot inventory in circulation remaining scarce, holders demonstrated a strong inclination to firm up prices, keeping spot premiums at consistently high levels. In the South China (Guangdong) region, the center of trading activity trended higher, with quotes ranging from 420,000 to 427,000 RMB/ton; bolstered by concentrated procurement from the electronics solder sector, prices in this region displayed notable resilience against downward pressure. In the Southwest—specifically Yunnan and Guangxi, the nation's core tin-producing hubs—ex-factory quotes were slightly lower than those in coastal regions. While spot supplies were relatively abundant, shipments from manufacturers remained cautious due to constraints imposed by a shortage of raw ore. The North China market relied primarily on sourcing from other regions, with quotes tracking the fluctuations in East China and maintaining a price spread of approximately 2,000 RMB/ton. Overall, the spot market was characterized predominantly by purchases driven by rigid demand, with limited speculative stockpiling; amidst the high-price environment, downstream consumers adopted a strategy of replenishing inventory strictly on an as-needed basis while maintaining a cautious stance regarding stock preparation. II. Domestic Production Capacity and the Global Supply-Demand Landscape
Domestically, China stands as the world's largest producer and consumer of refined tin. Production capacity is concentrated in two major regions: Yunnan and Guangxi. However, the grade of domestic primary tin ore has been declining year by year; the self-sufficiency rate for indigenous ore sources stands at only around 30%, meaning that approximately two-thirds of smelting feedstock must be supplemented through imports of overseas tin concentrates. In April, the total output of refined tin from major domestic smelters reached 17,723 tons—a slight month-on-month increase, though a slight year-on-year decline. A shortage of tin concentrates and persistently low processing fees continue to constrain the scope for large-scale production expansion within the smelting sector.
On the supply side, the inherent scarcity of global tin resources has become increasingly pronounced. Based on current extraction rates, global tin ore reserves are projected to last for only another 15 years, while domestic mines currently in operation have a remaining mine life of just 12 years. With mine resumptions in Myanmar falling short of expectations, Indonesia tightening its tin export quotas, and logistics disruptions plaguing mining regions in the Democratic Republic of the Congo, the world's three major tin-producing nations are simultaneously curtailing their export supplies, leading to a continuous tightening in the global circulation of tin raw materials. On the demand side, a distinct pattern has emerged: traditional sectors remain stable, while emerging sectors are experiencing explosive growth. Demand from traditional applications—such as tinplate, standard solders, and tin-based chemicals—continues to maintain its customary volume. Meanwhile, AI computing centers, advanced semiconductor packaging, and new energy electronics have become the primary drivers of incremental demand growth. As global technology firms continue to ramp up investment in data center construction, the demand for tin in solder applications is rising year by year, serving as the single most critical factor boosting overall tin consumption. Furthermore, the demand for tin in electronic components for photovoltaic systems and power batteries is steadily expanding, thereby further solidifying the fundamental foundation of overall demand.
III. Customs Import and Export Data for Tin Products (April 2026)
In April, domestic imports of tin concentrates experienced a significant year-on-year decline; specifically, imports of tin ore from Myanmar fell by 22% month-on-month, recovering to only 30% of pre-suspension levels. Concurrently, Indonesia's exports of refined tin in April were slashed by half—both on a year-on-year and month-on-month basis—directly resulting in an insufficient replenishment of domestic import supplies; consequently, the year-on-year decline in imports of unwrought refined tin narrowed slightly. Exports of tin materials and solder products have maintained positive year-on-year growth; stable overseas orders for electronics and computing infrastructure components have driven an uptick in the export of value-added tin products. Imports of scrap materials for recycled tin production have seen a slight increase; against the backdrop of a shortage in primary ore supplies, recycled raw materials have become a crucial supplement to domestic smelting operations. Overall foreign trade data corroborates the reality of contracting overseas raw material supplies and the growing resilience of domestic finished product exports, indicating that the deficit in raw material imports must be bridged through recycled tin.
IV. Price Linkage Across the Entire Industry Chain
Upstream tin concentrates have continued to rise in price due to persistent disruptions in overseas supply; these elevated ore prices have effectively locked in high production costs for smelters. Consequently, domestic processing fees for tin concentrates have continued to decline, reflecting the top-down transmission of raw material costs throughout the chain. Midstream refined tin and solder ingots have tracked upward in tandem with spot benchmark prices, triggering a corresponding rise in quotations for downstream processing inputs such as tin powder and solder paste. The downstream sector exhibits significant divergence: enterprises in the semiconductor and computing infrastructure electronics sectors possess strong product pricing power, enabling them to readily absorb the rising costs of tin raw materials while maintaining stable order volumes. Conversely, manufacturers of general home appliances and low-end hardware face pressure from high prices, prompting them to gradually pursue raw material substitution and scale back production, resulting in a slight decline in overall industry operating rates. Tinplate manufacturers are adopting a procurement-on-demand strategy, utilizing long-term contracts to lock in costs and hedge against short-term market volatility. The recycled tin industry chain has benefited from these high raw material prices, seeing improved profitability in the recovery and processing of scrap circuit boards and tin dross, which has accelerated the commissioning of new projects within the domestic tin recycling sector.
V. Market Outlook and Forecast
In the short term, supported by the undiminished pace of AI computing infrastructure development and the difficulty in rapidly resuming overseas mining operations, spot tin prices are expected to remain in a high-level volatile range. While high prices may temporarily dampen end-user purchasing activity—potentially triggering minor price corrections—the downside risk remains limited. In the medium term, as supply disruptions in Myanmar and Indonesia are unlikely to be resolved quickly, and with global tin inventories hovering at historically low levels—compounded by the inability of recycled tin to immediately fill the primary ore deficit—the central price trajectory for tin retains upward momentum. In the long term, the fundamental logic regarding the scarcity of global tin resources remains unchanged. Given that the AI and new energy electronics sectors represent long-cycle growth trajectories, the sustainability of new tin demand is clearly established. As the industry chain accelerates its transition toward recycling and recovery models, the overall tin market is expected to maintain a high-level operational pattern, with periodic price fluctuations driven primarily by short-term shifts in purchasing rhythms.
