Market evolution: Unwrought tin (CN 8001) — 2015–2025

Introduction

This report analyses the evolution of EU trade in Unwrought tin (CN 8001) over the period 2015–2025. The product heading covers unwrought tin, not alloyed (800110) and unwrought tin alloys (800120). Over the decade, the EU's tin trade has been shaped by three major dynamics: a dramatic price surge that inflated trade values even as physical volumes shifted, a significant geographic realignment of both suppliers and export destinations, and a structural reduction in the EU's external dependency. This report examines each of these dynamics in turn.

I. A Price-Driven Market: Soaring Values Amidst Divergent Volume Trends

The most striking feature of the EU's unwrought tin trade between 2015 and 2025 is the decoupling of trade values from physical volumes. Across both imports and exports, unit prices roughly doubled, inflating the monetary value of trade flows while underlying volume trends pointed in different directions.

Import volumes fell sharply while import values still rose

Over the period, EU import quantities of unwrought tin declined from 56,878 tonnes in 2015 to 31,381 tonnes in 2025 — a drop of 44.8%. Despite this steep decline, the total value of imports rose from €727 million to €902 million (+24.1%). The explanation lies entirely in unit prices, which climbed from €12,785/t to €28,749/t (+124.9%), more than compensating for the volume contraction.

Export growth was likewise dominated by price appreciation

EU exports grew more modestly in volume (+12.8%, from 6,382 to 7,198 tonnes) but surged in value (+131.9%, from €99 million to €231 million). Export unit prices rose from €15,589/t to €32,047/t (+105.6%), mirroring the trend on the import side and reflecting a global tin price boom that peaked around 2022.

Price shocks concentrated around 2021

The volatility and shock analysis reveals that the most pronounced price abnormalities clustered around 2021, a year of post-pandemic supply disruptions and surging demand for industrial metals. Three notable shock events stand out:

Indonesia — the EU's largest tin supplier — saw import unit prices jump 59% in a single year, which, given its 40.6% share of import value, had an outsized impact on total EU import costs.

Both product segments experienced similar price trajectories

Breaking the data down by sub-product, both non-alloyed tin (800110) and tin alloys (800120) saw comparable price trends. Non-alloyed tin import prices rose from €12,842/t to €29,267/t (+128%), while alloy prices climbed from €11,303/t to €21,926/t (+94%). Notably, alloy export prices surged even more dramatically, reaching €39,273/t in 2025 — a 121% increase from 2015 — suggesting strong demand for processed tin alloys in downstream manufacturing.

II. Geographic Realignment: Shifting Suppliers and New Export Frontiers

Beyond the price story, the period witnessed a substantial reconfiguration of the EU's trading partners for unwrought tin, with some traditional relationships weakening and new ones emerging with force.

The import side: rise of South American and Chinese suppliers, decline of Southeast Asian and UK sources

The composition of the EU's top import partners changed markedly over the decade. Indonesia remained the single largest supplier throughout, but its share eroded (−20.3% in value). The most dramatic growth came from:

China's ascent from a marginal supplier (€11.5 million, 2015) to the third-largest import source (€116.2 million, 2025) is the most striking single shift, potentially reflecting both China's growing role as a tin refiner and changes in re-export patterns. Meanwhile, the near-total collapse of UK-origin imports (−97.8%) is consistent with the UK's post-Brexit departure from the EU customs union, which likely redirected trade flows. Malaysia's steep decline (−72%) suggests a structural shift away from Southeast Asian sourcing.

The export side: new frontiers in Asia and the Western Balkans

EU export destinations also diversified substantially:

Japan's emergence as a major export destination (from €1.8 million to €50.7 million) and the rapid growth of shipments to Bosnia and Herzegovina suggest the EU has developed new downstream processing relationships. The US also became a far larger buyer, likely reflecting reshoring or friend-shoring trends in critical minerals supply chains. The decline in UK-bound exports mirrors the fall in UK-origin imports, underscoring the bilateral trade disruption caused by Brexit.

Both import and export markets became less concentrated

The Herfindahl-Hirschman Index (HHI) — a standard measure of market concentration — fell significantly on both sides of the ledger:

For imports, the drop from 2,312 to 1,364 moves the market from a moderately concentrated structure into a more competitive one (a score below 1,500 is generally considered unconcentrated). This diversification is consistent with the rise of multiple new suppliers — China, Brazil, and Bolivia — reducing the EU's reliance on any single origin.

Volatility varies widely across partners

The coefficient of variation (CV) of trade values reveals that some partnerships are far more volatile than others:

The high volatility of UK trade (CV of 1.51 for imports, 0.78 for exports) is a direct consequence of the abrupt post-Brexit trade disruption. Russian-origin imports also show high volatility (CV 1.36), which may reflect geopolitical disruptions and sanctions-related effects, though Russia's absolute share of EU tin imports remained small.

III. Toward Greater Autonomy: Reduced Import Dependency and Shifting EU Production

A third major narrative concerns the EU's evolving structural position in the global tin market. Several indicators point toward a reduction in external dependency, even as the EU remains a substantial net importer.

Net import reliance fell significantly

The net import reliance — defined as imports minus exports, divided by domestic production plus imports minus exports — declined from 82.9% in 2015 to 53.9% in 2025, a reduction of 34.9%. This means that by 2025, roughly half of the EU's apparent consumption of unwrought tin was met by domestic production, up from less than one-fifth a decade earlier.

The dramatic fall in export propensity — from 145.9% to 40.6% — indicates that the EU has increasingly retained tin within its borders rather than re-exporting it, consistent with growing domestic downstream demand (e.g., for electronics, soldering, and battery applications).

EU production grew in both volume and value

EU production data confirms a meaningful expansion of domestic output:

Production volume grew by a modest 18.7%, but production value surged by 473.7%, again reflecting the global tin price boom. The production peak occurred around 2018–2019 in volume terms (27,559 tonnes), after which output moderated — possibly reflecting the closure or scaling back of certain smelting operations.

A handful of EU member states dominate the bloc's tin specialisation

The specialisation analysis for 2025 reveals a highly concentrated intra-EU production landscape:

Belgium and the Netherlands together account for nearly two-thirds of EU unwrought tin production by volume, while most other member states have negligible or zero output. This concentration means that disruptions to Belgian or Dutch smelting capacity could have outsized effects on EU supply security.

EU member state import patterns shifted alongside geographic realignment

The EU's internal import geography also evolved:

Belgium and Poland saw the most dramatic growth in imports, consistent with their expanding production and re-export roles. Germany, traditionally a major importer, saw its share decline slightly, while the Netherlands remained the EU's largest single importer despite a modest contraction.

On the export side, Poland emerged as the EU's largest exporter by value (€76.8 million, up from just €1.2 million), overtaking the Netherlands (which collapsed from €43.3 million to €4.3 million, −90.1%). Austria and Spain also grew rapidly as exporters.

Conclusion

Over the 2015–2025 period, the EU's unwrought tin trade underwent a fundamental transformation. The dominant story is one of price-driven value inflation: global tin prices roughly doubled, inflating trade values even as import volumes contracted by nearly half. Beneath this price effect, the EU's supply geography was radically reshaped — South American suppliers (Brazil, Bolivia) and China surged, while traditional partners (UK, Malaysia) faded. The concentration of both import and export markets fell markedly, reducing single-source risks.

At the same time, the EU's structural dependency on external tin declined meaningfully, with net import reliance falling from 83% to 54%. Domestic production expanded, and the EU increasingly retained tin for its own downstream industries rather than re-exporting it. However, this production remains concentrated in just two member states (Belgium and the Netherlands), which represents a different kind of vulnerability at the intra-EU level.

Looking ahead, the key risks for the EU tin market include continued price volatility (particularly given the 2021 shock precedent), geopolitical supply disruptions (evidenced by the high volatility of Russian-origin flows), and the ongoing restructuring of global supply chains that has already redrawn the EU's tin trade map over the past decade.
