Market evolution: Unwrought tin (CN 800110) — 2015–2025

Introduction

Unwrought non-alloyed tin (CN 800110) is a critical industrial metal used primarily in soldering, tinplate, and chemical applications. The European Union has historically depended heavily on imports to meet its tin needs. Over the 2015–2025 decade, the EU's trade profile for this commodity has undergone a dramatic transformation. Import volumes were nearly halved while the total import bill still grew, driven by a more-than-doubling of unit prices. At the same time, the EU's net import reliance fell from 91.5% to 61.8%, signalling a structural shift toward greater self-sufficiency. This report analyses the main dynamics behind these changes across three dimensions: the decoupling of volumes from values, the geographic reorientation of supply chains, and the role of domestic production growth and price shocks.

1. Volume Down, Price Up: The Decoupling of Trade Quantities from Values

The most striking feature of EU tin trade over this decade is the sharp divergence between physical volumes and monetary values. Import quantities fell by nearly half, yet the total import bill expanded by over 20% — a paradox explained almost entirely by the explosion in unit prices.

1.1 Import volumes contracted by 47% while the import bill grew by 21%

EU imports of unwrought tin tell a paradoxical story. Over the full period, import volumes fell from 54,763 tonnes to 29,165 tonnes (−46.7%), while the total value rose from €703.3 million to €853.6 million (+21.4%). The minimum import quantity recorded was 26,795 tonnes, and the peak import value reached €1,119.8 million, illustrating the magnitude of the price-driven divergence.

This dynamic implies that the EU's import dependency in volume terms has been substantially reduced, even as each tonne of tin imported now costs more than twice what it did at the start of the period.

1.2 Export values more than doubled on modest volume gains

On the export side, EU shipments of unwrought tin grew only modestly in volume — from 5,164 tonnes to 5,935 tonnes (+14.9%) — yet export values surged from €77.8 million to €181.1 million (+132.7%). The unit export price rose from €15,068/t to €30,509/t (+102.5%), closely mirroring the import price trajectory.

The fact that export values grew far faster than export volumes confirms that price appreciation — rather than physical trade expansion — has been the dominant force shaping EU tin trade economics.

1.3 The trade deficit remained broadly stable in value despite a volume shift

The EU's tin trade balance moved from −€625.5 million in 2015 to −€672.5 million in 2025 (−7.5%, i.e. a modestly wider deficit). In net volume terms, however, the picture is very different: net imports (imports minus exports) fell from approximately 49,600 tonnes to about 23,200 tonnes — a reduction of over 53%. The persistently negative balance in value terms, despite halved net import volumes, underscores how elevated tin prices have sustained the EU's import bill even as its physical dependency has declined.

2. Rebalancing the Supplier Map: Latin America and China Ascendant

Alongside the volume-price decoupling, the geographic composition of the EU's tin trade has shifted profoundly. Traditional suppliers in Southeast Asia and the United Kingdom have lost ground, while Latin American producers and China have surged to prominence.

2.1 Indonesia and Malaysia — long-standing Asian anchors — have declined

Indonesia and Malaysia have historically been among the EU's most important tin suppliers. Indonesia remained the largest single supplier in 2025 (€215.2 million), but its share has fallen from €270.6 million in 2015 (−20.4%). Malaysia's decline was steeper: imports dropped from €65.3 million to €18.4 million (−71.8%). The United Kingdom, once a significant supplier (€49.9 million in 2015), has virtually disappeared from the EU's import ledger (€37,249 in 2025, a −99.9% decline), a development clearly linked to post-Brexit trade reconfiguration.

2.2 Brazil, Bolivia, and China have become major new sources

Partially offsetting these declines, three suppliers recorded extraordinary growth. Brazilian tin imports rose from €28.7 million to €127.8 million (+345.3%). Bolivian imports grew from €27.1 million to €113.7 million (+318.8%). Most strikingly, Chinese tin exports to the EU surged from €11.5 million to €116.0 million (+911.7%), making China the fourth-largest supplier by 2025. Peru remained a steady and important source, growing modestly from €113.2 million to €126.1 million (+11.4%).

The combined effect is a supplier base that is notably more geographically diversified and less dependent on any single producing region.

2.3 Import concentration has fallen significantly, reducing single-partner risk

The Herfindahl-Hirschman Index (HHI) for tin imports fell from 2,472 in 2015 to 1,508 in 2025 (−39.0%), moving the market from a "highly concentrated" threshold (above 2,500) to a "moderately concentrated" one. Export concentration followed a similar path, declining from 3,316 to 2,065 (−37.7%). These falling HHI values confirm what the partner data shows: the EU's tin trade has become meaningfully less dependent on a small number of dominant partners, which reduces supply-chain vulnerability.

On the export side, a parallel reorientation is visible. The United Kingdom was the EU's largest export destination in 2015 (€42.4 million) but fell to €9.1 million by 2025 (−78.6%). Meanwhile, Japan grew from €1.8 million to €50.5 million (+2,768%), the United States from €11.3 million to €55.0 million (+388.2%), and Bosnia and Herzegovina from €0.04 million to €28.8 million — a remarkable expansion likely reflecting the development of tin-consuming industrial capacity in Southeast Europe.

3. Domestic Capacity Growth, Internal Specialisation, and the 2021 Price Shock

The EU's declining import reliance cannot be explained by trade reorientation alone. A significant expansion of domestic tin production, anchored by Belgium and the Netherlands, has played a central role. This growing internal capacity arrived alongside a severe price shock in 2021 that tested the resilience of the entire supply chain.

3.1 EU domestic tin production has expanded substantially

EU production of unwrought non-alloyed tin rose from 10,000 tonnes to 15,000 tonnes (+50.0%) in quantity terms. In value terms, the growth was far more dramatic: from €40 million to €350 million (+775.0%), with a peak of €426.5 million recorded during the period. This suggests that EU smelters and refiners have not only increased throughput but have also captured much of the global price appreciation in their output values. The combination of rising domestic volumes and soaring prices has been the single most important factor in reducing the EU's net import reliance from 91.5% to 61.8%.

3.2 Belgium and the Netherlands anchor the EU's tin value chain

Within the EU, tin trade and production are heavily concentrated in two member states. Belgium displays the highest revealed comparative advantage (RCA of 4.13, RSCA of 0.61), followed by the Netherlands (RCA of 2.57, RSCA of 0.44). Together, they account for over 72% of the EU's production share in this product category. On the import side, the Netherlands was the EU's largest entry point (€342.5 million in 2025, though down from €384.8 million), while on the export side, Belgium (€59.3 million) and Poland (€76.7 million, up from just €0.8 million in 2015) emerged as the leading re-export hubs. Poland's transformation from a marginal exporter to the EU's second-largest is particularly noteworthy and may reflect new refining or trading capacity.

3.3 The 2021 price shock was a defining event for the decade

The volatility analysis reveals that 2021 was a year of exceptional price disruption across multiple trade corridors simultaneously. Three major shocks were detected:

The Indonesia import shock was by far the most consequential, given that Indonesia alone accounted for 42.2% of EU tin import value. A 64.5% abnormal price increase on such a large share would have had immediate and widespread effects on EU manufacturers' input costs. The simultaneous shocks in Japanese and Bosnian export prices suggest that 2021 marked a global repricing event — consistent with the broader commodity supercycle and post-pandemic supply-chain disruptions observed across metals markets during that year.

Beyond these acute shocks, several trade corridors exhibited persistently high volatility. Imports from the United Kingdom (coefficient of variation of 1.59) and Russia (CV of 2.16) were the most volatile, while on the export side, Bosnia and Herzegovina (CV of 1.61) and Canada (CV of 2.04) showed the greatest instability. These high-volatility corridors tend to be smaller in absolute terms, but they highlight niches of the trade network that are prone to sudden disruption.

Conclusion

The EU's unwrought tin trade has been reshaped over the 2015–2025 decade by three interlocking dynamics. First, a structural decoupling of volumes from values: import quantities were nearly halved while unit prices more than doubled, meaning the EU now moves far less physical tin but at significantly higher cost. Second, a geographic rebalancing of supply chains: traditional Asian suppliers (Indonesia, Malaysia) and the United Kingdom lost market share to a rising cohort of Latin American producers (Brazil, Bolivia) and China, resulting in a meaningfully less concentrated — and therefore less vulnerable — supplier base. Third, a substantial expansion of EU domestic production capacity, driven primarily by Belgium and the Netherlands, has been the main factor in reducing the EU's net import reliance from 91.5% to 61.8%.

These structural shifts have unfolded against the backdrop of the 2021 global price shock, which tested the resilience of the entire tin supply chain and contributed to a sustained period of elevated prices. Looking ahead, the EU's reduced import dependency and more diversified supplier base represent meaningful improvements in strategic autonomy for this critical industrial metal — though the persistently high unit prices remain a cost challenge for downstream European manufacturers.
