Global Tin Mining Companies: The Top 10 Producers Defining 2024 Supply Dynamics

The global tin market entered a critical inflection point in 2023, with production numbers revealing significant shifts in how the world’s leading tin mining companies are navigating supply challenges and demand uncertainty. Global tin output contracted by 2.1 percent year-over-year in 2023, settling at 370,100 metric tons across all major manufacturing operations. This slowdown, paired with market overcapacity, created a surplus of approximately 9,700 tonnes—a clear signal of the strains affecting contemporary production strategies.

China’s dominance in tin mining companies remains unshaken, with the nation’s combined output reaching 68,000 metric tons in 2023. Myanmar followed as the secondary producer at 54,000 MT. However, the composition of these markets is more nuanced than headline rankings suggest. According to the International Tin Association, the anticipated recovery in global demand, coupled with ongoing disruptions—particularly in Myanmar’s Wa State and Indonesian mining regions—positioned 2024 as a potential inflection point for supply tightness. This shift has already manifested, with tin prices reaching significant highs as supply uncertainty tightened market conditions.

China’s Expanding Leadership in Tin Manufacturing

The dominance of Chinese tin mining companies within global production cannot be overstated. Three of the top six refined tin manufacturers hail from China, collectively representing a substantial portion of worldwide capacity. This concentration reflects decades of investment in integrated production facilities, technical expertise, and access to rich ore deposits.

1. Yunnan Tin Company – The Global Heavyweight

Yunnan Tin Company stands as the world’s largest tin mining company by output, producing 80,100 metric tons of refined tin in 2023—representing a nearly 4 percent year-over-year increase. Listed on the Shenzhen Stock Exchange under ticker SZSE:000960, the company operates as a subsidiary of state-owned Yunnan Tin Group (Holding) Company, whose operational heritage extends back to 1883. Beyond tin refining, Yunnan Tin Company manages China’s largest precious metals research and development infrastructure, positioning it as both a production and innovation powerhouse within the tin mining companies sector.

3. Yunnan Chengfeng Non-ferrous Metals – China’s Secondary Force

Established in 1994, Yunnan Chengfeng Non-ferrous Metals ranks as China’s second-largest tin producer and globally the third-largest tin manufacturing entity. In 2023, the company expanded its refined tin output by 5.8 percent to reach 21,800 metric tons. Beyond tin, the operation manufactures indium, silver, gold, lead, bismuth, and antimony, reflecting the polymetallic nature of modern tin mining companies that optimize resource extraction efficiency.

6. Guangxi China Tin – Rising Through Diversification

Guangxi China Tin, established in 1990, operates as the nation’s third-largest tin producer. In 2023, the private enterprise produced 12,000 metric tons of refined tin, representing a 10.1 percent production increase from 2022. The company’s growth trajectory—climbing from the 10th position in 2021 to the 6th position by 2023—demonstrates how tin mining companies leverage diversification. Beyond tin, Guangxi manufactures indium, lead, antimony, zinc, silver, cadmium, and bismuth.

International Tin Mining Companies: Key Players Beyond China

While Chinese tin mining companies dominate by volume, significant manufacturing capacity exists across Peru, Malaysia, Indonesia, Bolivia, Belgium, and Thailand. These operations collectively represent both legacy operations and emerging producers reshaping the global supply landscape.

2. Minsur – South American Production Leadership

Peru-based Minsur represents privately held excellence within tin mining companies, delivering 31,700 metric tons of refined tin in 2023—a 3.1 percent decline from prior-year levels. The company’s integrated supply chain encompasses its Taboca subsidiary in Brazil, complementing its flagship San Rafael mine in South America, which Minsur has operated since 1977. This facility alone produces approximately 12 percent of global tin supplies, making it a cornerstone asset among international tin mining companies. Minsur traces its roots to the early 20th century and operates integrated smelting and refining infrastructure alongside mining operations.

4. Malaysia Smelting – The Specialist Smelter

Malaysia Smelting produced 20,700 metric tons of refined tin in 2023, representing a 10.1 percent output expansion. Listed on the Kuala Lumpur Stock Exchange (KLSE:MSC), this more-than-century-old enterprise—operational since 1887—serves as a subsidiary of Singapore’s Straits Trading Company (SGX:S20). The company operates as an integrated specialist, providing custom smelting services alongside its own refined tin production, exemplifying how tin mining companies often combine merchant services with direct manufacturing.

5. PT Timah – Struggling With Structural Challenges

Indonesia’s state-owned PT Timah, established in 1976, experienced a challenging 2023 with refined tin production declining 22.7 percent to 15,300 metric tons. The company, headquartered in Bangka-Belitung province, manages the complete tin supply chain from exploration through marketing. However, production has contracted sharply from 26,500 MT in 2021, reflecting both operational headwinds and reported corruption investigations within tin mining companies’ commodity trading operations. This represents a cautionary example of how regulatory and governance challenges can impact even historically significant producers.

7. Empresa Metalúrgica Vinto – Bolivia’s Processing Hub

Bolivia’s state-owned Empresa Metalúrgica (EM) Vinto processed 10,000 metric tons of refined tin in 2023, down 2.8 percent from 2022 levels. Rather than operating mines directly, EM Vinto functions as a processing facility, receiving material from mining cooperatives, independent miners, and tin concentrate suppliers. The company’s operations have been constrained by socio-political instability in the broader Andean region and domestic debt pressures affecting tin mining companies’ investment capacity.

Secondary Tier Producers: The Specialized Manufacturers

The final positions within the top 10 tin mining companies encompass specialized processors and emerging producers that collectively contribute meaningful global capacity. These manufacturers demonstrate how diverse operational models—from full vertical integration to specialized smelting—characterize the contemporary tin industry.

8. Jiangxi New Nanshan – The Emerging Manufacturer

Jiangxi New Nanshan represents a relative newcomer to global tin manufacturing, launching its first smelter in 2009 with a designed capacity of 10,000 metric tons annually. Despite explosive 122 percent growth in 2019, the company’s refined output declined 12 percent in 2023 to 9,500 metric tons, reflecting broader market pressures facing emerging tin mining companies navigating commodity cycles.

9. Aurubis Beerse – Europe’s Recycling Specialist

Belgium-based Aurubis Beerse produced 9,300 metric tons of refined tin in 2023, expanding output 13.4 percent to capture the 9th position among global tin mining companies. The facility operates a unique recycling and refining installation processing secondary raw materials for copper, tin, lead, and nickel production. Aurubis positions itself as Europe’s largest tin producer and emphasizes sustainability through zero-waste production methodology, with tin ingots known for exceptionally low lead content.

10. Thailand Smelting and Refining – The Legacy Operator

Thailand Smelting and Refining, commonly known as Thaisarco, has operated since 1963 as a private manufacturer of tin, tin alloys, and tin-related value-added products. In 2023, the company produced 9,200 metric tons of refined tin, down 3.2 percent from prior year. Under operational management from the UK’s Amalgamated Metal since 1995, Thaisarco secured a three-year offtake agreement with Andrada Mining in November 2023, ensuring supply of at least 90 metric tons monthly from Namibia’s Uis mine operation.

The Consolidating Landscape for Tin Manufacturing

The collective output of these 10 tin mining companies represents approximately 59 percent of total global refined tin production, illustrating significant market concentration. This consolidation reflects both the technical requirements of modern smelting operations and the geographic clustering of ore deposits and energy infrastructure necessary for efficient production. As supply disruptions persist in key production regions and macroeconomic recovery continues, the competitive positioning and production volumes of these tin mining companies will remain central to global metals markets throughout 2024 and beyond.
