Market evolution: Silver-clad base metals semi-manufactured (CN 7107) — 2015–2025

Introduction

This report examines the evolution of EU extra-Union trade in CN 7107 — base metals clad with silver, not further worked than semi-manufactured — over the period 2015 to 2025. This product category, mapped to Prodcom code 24.41.50.30, covers semi-manufactured articles (such as sheets, strips, tubes and wire) in which a base-metal core is bonded with a silver cladding. The material finds applications in electrical contacts, jewellery components, tableware and industrial tooling, sectors where the cost of solid silver can be mitigated by a clad construction.

Over the eleven-year window, the EU market for this product has undergone a profound structural transformation. Three interlinked dynamics stand out: a dramatic divergence between surging trade values and collapsing physical volumes, a sweeping reconfiguration of the EU's partner geography, and a decisive shift from the EU being a net exporter to a net importer — reflecting a steep decline in domestic production capacity. The following sections develop each of these observations in turn.

1. A Price-Driven Market: Surging Trade Values Amid Shrinking Volumes

The most striking feature of the 2015–2025 period is the sharp divergence between trade values and physical quantities. Both EU exports and imports grew substantially in euro terms, yet the underlying volumes tell a very different story — one of contraction on the export side and near-stagnation on the import side.

Export values rose while export volumes collapsed

EU exports of CN 7107 grew from EUR 8.9 million in 2015 to EUR 12.3 million in 2025, a gain of 37.5%. Over the same period, export volumes fell from 94.9 tonnes to just 41.6 tonnes, a decline of 56.1%. This implies that the average unit export price surged from approximately EUR 94,155 per tonne to EUR 294,287 per tonne — an increase of 212.6%.

The export volume trajectory was anything but linear. A major spike occurred in one year when volumes reached 1,428.8 tonnes — an extreme outlier likely linked to a large re-export or one-off consignment. That peak was followed by a steep correction, with volumes bottoming out at 38.4 tonnes before partially recovering. The minimum export unit price of EUR 9,714 per tonne (registered in the year of the volume spike) confirms that the high-volume episode involved low-value-per-kilogram shipments, likely bulk semi-manufactured forms, whereas the recent years' lower volumes at much higher unit values suggest a shift toward more specialised, value-added products.

Import values nearly doubled with only marginal volume growth

EU imports tell a parallel story. Import values rose from EUR 9.6 million to EUR 18.3 million (+91.3%), while volumes edged up only slightly from 161.9 tonnes to 169.1 tonnes (+4.4%). The average import unit price climbed from EUR 59,054 to EUR 108,249 per tonne (+83.3%), peaking at EUR 233,567 in an intermediate year.

Silver price dynamics are the dominant driver

The near-universal surge in unit prices — on both the import and export sides — points overwhelmingly to the underlying cost of silver as the principal driver. Silver-clad products inherit the price volatility of their precious-metal layer. Global silver prices rose markedly from the mid-2010s through the early 2020s, and the unit-price trajectories in the CN 7107 data are consistent with this pass-through effect. The divergence between value and volume does not necessarily indicate booming demand; rather, it largely reflects the revaluation of the silver content embedded in each tonne of semi-manufactured clad material.

2. A Reconfigured Partner Landscape: Diversification Away from Traditional Flows

Beyond price effects, the period witnessed a significant re-orientation of the EU's trade geography. Longstanding bilateral relationships weakened, while new partners — notably China and Türkiye — gained prominence, particularly on the import side. Concentration indices confirm that the market became more diversified over time.

The United Kingdom lost ground on both sides of the ledger

In 2015, the United Kingdom was the EU's single largest import partner (EUR 4.8 million) and a major export destination (EUR 2.8 million). By 2025, UK imports had fallen to EUR 2.9 million (−40.9%) and UK exports to EUR 2.1 million (−23.1%). Brexit-related trade friction, including new customs formalities and rules-of-origin requirements, likely contributed to this erosion, although the decline in UK import share began before the formal transition period ended.

China and Türkiye emerged as major import suppliers

The most dramatic shifts occurred on the import side. Chinese shipments to the EU surged from EUR 329,000 to EUR 3.6 million — a near-tenfold increase — while Turkish imports grew from a negligible EUR 3,481 to EUR 2.6 million. These two countries together went from representing a marginal share of EU imports to accounting for roughly one-third of total import value by 2025. This likely reflects the growing competitiveness of Chinese and Turkish precious-metal processing industries, combined with EU downstream demand from electronics, automotive and jewellery manufacturing. Japan also gained significantly (+292.6%), while India saw its share collapse (−92.1%).

Export destinations also shifted

On the export side, Switzerland grew from EUR 485,000 to EUR 1.6 million (+237.7%), Albania rose from EUR 137,000 to EUR 567,000 (+312.4%), and the United States expanded from EUR 463,000 to EUR 1.0 million (+115.8%). Turkey, by contrast, saw EU export flows decline by 41.8%. The growing role of Switzerland likely reflects the Swiss watchmaking and precious-metals refining industry, for which clad semi-manufactured forms are an intermediate input.

Market concentration fell on both import and export sides

The Herfindahl–Hirschman Index (HHI) for import concentration by value fell from 3,921 to 2,300 (−41.3%), and for exports from 1,301 to 801 (−38.5%). Both readings indicate a meaningful diversification of trade partners. The import-side HHI, which started above the commonly cited 2,500 threshold for a "moderately concentrated" market, ended well below it — suggesting that the EU's import supply base became substantially less reliant on any single country over the decade.

3. From Net Exporter to Net Importer: The Erosion of EU Production Capacity

Perhaps the most consequential structural shift over the 2015–2025 period was the EU's transition from a position of slight net self-sufficiency to one of net import dependence, driven by a severe contraction of intra-EU production.

EU production of silver-clad semi-manufactures contracted sharply

According to production data, EU production of CN 7107 fell from 184,624 kg in 2015 to just 60,000 kg in 2025 — a decline of 67.5%. Production value dropped from EUR 60.6 million to EUR 30.0 million (−50.5%), having bottomed out at EUR 20.0 million at one point during the period. These figures point to a substantial withdrawal of manufacturing capacity: fewer EU-based plants producing clad semi-manufactured forms, or existing plants operating well below capacity.

Net import reliance flipped from surplus to deficit

In 2015, the EU registered a net import reliance of −9.6%, meaning it was a net exporter of CN 7107 to the rest of the world. The trade balance stood at approximately −EUR 624,000 (i.e., exports exceeded imports). By 2025, net import reliance had swung to +8.2%, and the trade deficit had widened to EUR 6.0 million. At one intermediate point, the deficit reached its minimum at approximately EUR −6.0 million.

Trade intensity more than doubled, signalling growing exposure

The trade intensity ratio — defined as total extra-EU trade (imports + exports) as a share of apparent consumption — rose from 22.6% to 50.7%. This means that by 2025, roughly half of the EU market for silver-clad semi-manufactures was accounted for by cross-border flows, up from less than a quarter in 2015. Export propensity also increased from 16.6% to 31.0%. These rising ratios reflect both the decline in domestic production and the growing embeddedness of the EU in global silver-clad supply chains.

Germany dominates EU production but is increasingly import-dependent

Among EU member-state reporters, Germany stands out both as the largest exporter (EUR 7.7 million in 2025, up 9.1% from 2015) and, increasingly, as the largest importer (EUR 6.5 million, up 988.5%). Germany's revealed comparative advantage (RCA of 4.27 with an RSCA of 0.62) confirms a genuine specialisation in this product. Yet even Germany's import bill grew dramatically, suggesting that German manufacturers of clad products increasingly source their semi-manufactured inputs from outside the EU, or that the country's downstream industries (e.g., electrical contacts, automotive connectors) are importing finished clad forms directly.

Sweden and France round out the top three importers among EU members, with Sweden's imports reaching EUR 4.7 million (+128.7%) and France's declining to EUR 2.7 million (−40.6%). On the export side, France (EUR 1.9 million, +181.0%) and Italy (EUR 2.0 million, +369.5%) emerged as notable second-tier exporters alongside Germany.

Conclusion

Over the 2015–2025 decade, the EU market for silver-clad base-metal semi-manufactures (CN 7107) underwent three simultaneous and reinforcing transformations. First, the silver price cycle inflated unit values on both the import and export sides, masking a real contraction in physical trade volumes — particularly on the export side, where volumes fell by more than half. Second, the EU's trade geography was substantially reconfigured: the United Kingdom's role diminished on both sides, while China and Türkiye rose to prominence as import suppliers, and Switzerland and Albania grew as export destinations. Market concentration fell meaningfully, indicating a more diversified — but also more complex — supply base. Third, and most consequentially, EU production capacity eroded severely, flipping the bloc from a net exporter to a net importer and doubling its trade-intensity exposure.

These trends carry implications for EU industrial and trade policy. The decline in domestic production, combined with rising import dependence and high unit-value exposure to silver price swings, suggests that the EU's strategic autonomy in silver-clad materials has weakened over the period. Monitoring the continued evolution of this niche but strategically relevant product — particularly in the context of supply-chain resilience debates and the EU's Critical Raw Materials framework — will remain important in the years ahead.
