Top Tin-Producing Countries: Rankings, Output, and Market Role

Tin-producing countries defined Tin mining is concentrated in a handful of countries, with China, Indonesia, Myanmar, Peru, Bolivia, and the Democratic Republic of Congo (DRC) accounting for the vast majority of global output. World tin mine production runs at approximately 300,000-320,000 tonnes per year. The LME tin contract (ticker SN) is the global price benchmark, traded in 5-tonne lots. Tin’s largest single use is solder for electronics — roughly 47% of consumption — and demand is growing with semiconductor manufacturing expansion and the rise of AI hardware.

Global Tin Production Rankings

Global mine production of tin runs at approximately 300,000-320,000 tonnes per year (refined tin equivalent). The production landscape has shifted significantly in recent years, particularly with Myanmar’s rapid rise.

Approximate 2023-2024 rankings:

Rank	Country	Estimated Output (kt/yr)	Share of World
1	China	~85-95	~30%
2	Myanmar	~55-65	~18-20%
3	Indonesia	~55-65	~18-20%
4	Peru	~20-25	~7-8%
5	Bolivia	~15-18	~5-6%
6	DRC	~10-15	~4-5%
7	Australia	~6-8	~2%
8	Brazil	~5-8	~2%

Myanmar and Indonesia are now effectively tied for second place — and Myanmar is the faster-moving story. This represents a dramatic shift from even five years ago, when Indonesia was comfortably the world’s second-largest producer and Myanmar barely registered in global statistics.

Data note: Myanmar tin production figures carry high uncertainty because a significant portion of mining is artisanal and small-scale, not captured in official government statistics. Some industry analysts estimate actual Myanmar output is higher than reported figures.

China: The Dominant Producer

China is the world’s largest tin miner, smelter, and consumer. Its dominance spans every part of the supply chain, which is unusual even among China’s commodity positions.

Primary tin mining regions in China include:

• Yunnan province — home to the Gejiu mining district, historically China’s most important tin area
• Guangxi province — significant production from polymetallic ore bodies
• Inner Mongolia — smaller but growing volumes

China’s Yunnan Tin Group is the world’s largest tin smelter, processing both domestic Chinese ore and imported concentrates from Myanmar, Indonesia, and elsewhere.

China’s role as both a major miner AND major refiner creates a structural position. When domestic ore grades decline or face stricter environmental compliance requirements, Chinese smelters import ore — primarily from Myanmar (via land border crossing at Muse/Ruili) and from Indonesia (maritime shipment). This import dependence on Myanmar concentrate creates supply chain exposure when Myanmar political instability or military actions disrupt mining.

China’s domestic tin consumption is driven by its electronics manufacturing sector — the largest in the world. Shenzhen and the Pearl River Delta concentration of electronics assembly means China is both the world’s largest tin producer and one of its largest consumers.

Indonesia: Declining Output, Rising Governance Concerns

Indonesia was the world’s second-largest tin producer for many years, with production centered on the islands of Bangka and Belitung in the South China Sea. At peak output, Indonesia produced over 100,000 tonnes per year.

Production has fallen substantially — now estimated in the 55,000-65,000 tonne range — due to:

• Declining ore grades in the Bangka-Belitung alluvial (placer) deposits. The easy-to-mine shallow deposits are increasingly exhausted.
• Environmental enforcement cracking down on illegal offshore tin dredging (“tin pirates”) around Bangka
• PT Timah issues: Indonesia’s state-owned tin miner, PT Timah, faces governance and legal challenges. In 2024, a major corruption investigation linked to Timah’s tin trading practices resulted in arrests and investigations that disrupted operations and market confidence.

Indonesia requires tin exports to go through the Indonesia Commodity and Derivatives Exchange (ICDX) or the Jakarta Futures Exchange (BBJ), which provides a level of export verification. Indonesian tin exports are an important price signal — when Indonesian export volumes decline, global tin prices typically strengthen.

The Bangka-Belitung environmental situation is a genuine concern. Decades of mining have left extensive ecological damage, and stricter environmental enforcement (which reduces supply) conflicts with local economic dependence on tin mining as a primary industry.

Myanmar: The Fastest-Growing Tin Story

Myanmar has emerged as one of the world’s largest tin producers in a remarkably short time. Production is centered in the Wa Region of Shan State, in northern Myanmar near the Chinese border — an area controlled not by the central Myanmar government but by the United Wa State Army (UWSA), a powerful non-state armed group.

Most Myanmar tin mining is alluvial (placer deposits) and artisanal to semi-mechanized in scale. The ore is transported overland to China, processed at Yunnan smelters, and enters the global supply chain as Chinese-refined tin. This supply chain structure means Myanmar’s contribution to global supply is often invisible in “Chinese” tin statistics.

Myanmar’s rise in tin production carries significant supply chain risks:

1. Political instability: Myanmar has been in civil conflict since the 2021 military coup. Fighting between the military junta and various resistance forces has disrupted transport routes, including the tin ore supply corridor to China.

1. Conflict mineral designation: Tin from Myanmar’s Wa Region has been flagged by industry groups and downstream electronics companies as carrying conflict mineral risk. The UWSA derives revenue from mineral production, and questions about compliance with the OECD Due Diligence Guidance are live.

1. Data opacity: Official Myanmar production statistics are unreliable for the Wa Region. Industry estimates vary widely.

1. Abrupt supply disruptions: In 2023, the UWSA temporarily halted tin mining operations — ostensibly for environmental and resource conservation reasons — causing a significant spike in global tin prices on the LME, as Myanmar/Wa Region supply is material to the global market.

Any electronics company sourcing tin for solder needs to understand Myanmar’s role in global supply. A disruption to Wa Region production moves the LME tin price by measurable amounts — and has done so repeatedly.

Peru and Bolivia: Latin American Hard Rock Mining

Peru produces approximately 20,000-25,000 tonnes of tin per year, primarily from the San Rafael mine in Puno region (operated by Minsur, a Peruvian mining group). San Rafael is one of the world’s largest individual tin mines. Peruvian tin is hard rock underground mining, producing tin concentrates shipped to smelters.

Peru also refines some tin domestically — Minsur operates a smelter — and exports refined tin metal as well as concentrates.

Bolivia produces 15,000-18,000 tonnes per year from the Cerro Rico and Potosí mining districts — regions with centuries of mining history. Bolivian tin mining is a mix of state-owned enterprise (Empresa Minera de Bolivia, COMIBOL), medium enterprises, and artisanal cooperatives. Bolivia lacks domestic smelting capacity for all of its production and exports concentrates.

Both Peru and Bolivia produce tin from complex polymetallic ore bodies where tin occurs alongside silver, zinc, lead, and other metals. Byproduct economics — the value of the associated metals — affect the economic viability of tin mining in these regions.

DRC and Africa: Artisanal Production and Conflict Minerals

The Democratic Republic of Congo produces approximately 10,000-15,000 tonnes of tin per year, predominantly from the mineral-rich eastern provinces (North Kivu, South Kivu, Maniema). DRC tin mining is predominantly artisanal and small-scale mining (ASM) — individual miners using hand tools or simple machinery.

This creates a serious responsible sourcing challenge. Eastern DRC is a conflict zone where armed groups have historically taxed or controlled mining sites, using the revenue to fund armed operations. Tin, tungsten, tantalum, and gold from this region are collectively referred to as 3TG minerals or “conflict minerals” under US Dodd-Frank Section 1502 and EU Conflict Minerals Regulation.

DRC tin that is not verified as conflict-free cannot be used by public US companies in their products under Dodd-Frank. Electronics companies are required to trace their tin supply chain to verify whether DRC or adjoining country (AOC) tin is in their products and, if so, whether it comes from conflict-free sources.

Africa beyond DRC also contributes tin from Rwanda (some of which may include DRC-origin material), Nigeria, and South Africa — collectively adding perhaps another 5,000-8,000 tonnes annually.

What Tin Is Used For

Tin has a relatively narrow range of industrial applications compared to base metals like copper or aluminum, but those applications are concentrated in high-growth sectors.

Solder: 47% of global tin consumption. Electronic solder is a tin-based alloy (typically tin-silver-copper, SAC alloy, for lead-free solder; older tin-lead alloys are being phased out under RoHS regulations). Every circuit board, every chip package, every electronic connector is soldered using tin-based solder. As electronics production grows — and particularly as AI hardware (GPUs, high-bandwidth memory, server boards) scales up — solder demand grows proportionally. The AI and semiconductor boom of 2023-2025 has been cited as a structural driver of additional tin demand.

Tinplate: approximately 19% of consumption. Tinplate is a thin steel sheet electroplated with tin — used for food and beverage cans. The tin coating prevents corrosion and is food-safe. Demand is steady and global, tied to food packaging consumption.

Tin chemicals: approximately 14% of consumption. Organotin compounds are used as PVC stabilizers (preventing degradation) and as industrial catalysts. Lead-free PVC stabilization has been an area of growth.

Other uses: brass and bronze alloys, float glass manufacturing (tin baths for flat glass production), and specialty alloys.

The lead-free solder transition is significant: EU RoHS (Restriction of Hazardous Substances) Directive banned lead in most electronics solder from 2006 onward. Lead-free SAC solder contains roughly 95-97% tin, versus the old 60/40 tin-lead solder that was only 60% tin. This transition structurally increased tin’s share of solder content per circuit board.

LME Tin: How the Market Is Priced

Tin trades on the London Metal Exchange (LME) under the ticker SN (the chemical symbol for tin, from Latin: stannum). Key contract specifications:

• Contract size: 5 tonnes
• Delivery locations: LME-approved warehouses globally (predominantly in Asia and Europe)
• Grade: refined tin, minimum 99.85% purity
• Pricing: USD per tonne

LME tin prices are the global reference. Physical tin contracts worldwide are priced at LME spot or LME forward prices, with a premium or discount for grade, location, and physical delivery specifics.

Tin prices are significantly more volatile than most other base metals, for two main reasons. First, the market is small — global production is around 300,000-320,000 tonnes per year, tiny compared to copper at 25 million tonnes. A relatively small supply disruption or demand spike moves the price substantially. Second, LME tin has historically seen episodes of very low liquidity (thin order books) that amplify price moves.

Tin reached an all-time high of approximately $51,000/tonne in March 2022 following supply disruptions and the semiconductor boom. It subsequently fell sharply as the chip inventory cycle corrected in 2022-2023 before recovering.

LME warehouse stocks (published daily) are closely watched. When LME tin stocks fall sharply, it signals tightening physical supply and typically pushes the tin price into backwardation (near-term prices above forward prices).

Responsible Sourcing: ITSCI and Conflict Designation

ITSCI (ITRI Tin Supply Chain Initiative) is the primary responsible sourcing program for tin from the DRC and Great Lakes region of Africa. ITSCI operates a traceability and due diligence system: miners in participating areas tag their bags of ore with ITSCI tags, which are tracked through the supply chain from mine to smelter. Participating smelters that use ITSCI-tagged material are considered “conflict-free” for Dodd-Frank and EU regulation purposes.

ITSCI operates in DRC, Rwanda, Burundi, Uganda, and Tanzania. The program has faced criticism — including from the OECD — for gaps in coverage and implementation, and ITRI (the International Tin Association’s predecessor body) restructured the program in response.

Myanmar conflict designation: Unlike DRC, which has established programs like ITSCI, tin from Myanmar’s Wa Region has no equivalent verified responsible sourcing program. Several major electronics companies have flagged Myanmar-origin tin as an unverifiable conflict mineral risk. The Responsible Minerals Initiative (RMI) and industry guidance have highlighted this gap.

For electronics companies subject to Dodd-Frank Section 1502, SEC conflict mineral reporting rules, or EU regulations, Myanmar is an emerging compliance problem with no current clean solution equivalent to ITSCI.

Frequently Asked Questions

Why did LME tin prices spike in 2022?

Multiple factors combined: the global semiconductor boom post-COVID increased solder demand; supply disruptions in Myanmar (including UWSA mining halts) tightened ore supply; Indonesian export volumes were running below capacity. The combination of strong demand and constrained supply from two of the world’s top producers pushed prices to record highs above $51,000/tonne.

What is the UWSA and why does it matter for tin?

The United Wa State Army is a non-state armed group that controls the Wa Region of eastern Shan State, Myanmar. It is autonomous from the central Myanmar government and operates its own administration, military, and economy — including tin mining. Because the UWSA derives revenue from mineral production, tin sourced from this region raises conflict mineral compliance questions for downstream buyers.

How does AI demand affect tin prices?

AI hardware — particularly GPUs (graphics processing units) and high-bandwidth memory (HBM) used in AI training and inference servers — requires extensive circuit board assembly. More circuit boards, more solder joints. More solder joints, more tin. The AI infrastructure buildout from 2023 onward has been cited by the International Tin Association as a structural driver of incremental tin solder demand.

What is ITRI and who does it represent?

ITRI (now reorganized as the International Tin Association, ITA) is the global trade association for the tin industry, representing miners, smelters, traders, and users of tin. It publishes market data, operates the ITSCI responsible sourcing program, and advocates on regulatory and market issues.

What is the difference between tin concentrate and refined tin?

Tin ore extracted from mines is crushed and processed into concentrate — a material with elevated tin content (40-70% tin) but still containing gangue minerals and impurities. Concentrate is shipped to smelters, where it is smelted and refined to produce refined tin metal (99.85%+ purity) for sale on the LME or directly to end users. Indonesia and some other producing countries export both concentrates and refined metal.

Key Takeaways

• China is the world’s largest tin producer (~30% of global output), with production in Yunnan and Guangxi and the world’s largest smelting capacity via Yunnan Tin Group.
• Myanmar has emerged as a second-place or third-place producer (tied with Indonesia), with production from the Wa Region in Shan State, controlled by the UWSA non-state armed group.
• Indonesia’s tin production has declined from historical highs due to depleting alluvial deposits and environmental enforcement.
• The largest single use of tin is solder for electronics — approximately 47% of global consumption — and AI/semiconductor hardware expansion is a structural demand driver.
• LME tin (ticker SN) is the global benchmark, traded in 5-tonne lots; tin is one of the most price-volatile base metals due to the small size of the market.
• DRC tin carries Dodd-Frank/EU conflict mineral compliance obligations; ITSCI is the primary responsible sourcing verification system for the DRC and Great Lakes region.
• Myanmar tin from the Wa Region currently lacks a verified responsible sourcing program, creating unresolved compliance exposure for downstream electronics companies.
