Market evolution: Mineral insulating materials (CN 680690) — 2015–2025

Introduction

This report examines the trade evolution of EU product CN 680690 — a residual category covering mixtures and articles of heat-insulating, sound-insulating or sound-absorbing mineral materials not elsewhere classified (such as perlite products, calcium silicate boards, or mineral-based acoustic panels). Over the 2015–2025 period, the EU maintained a consistent trade surplus, but the underlying dynamics reveal a market shaped by dramatic unit-price inflation, a severe contraction in traded volumes, and a pronounced reshuffling of trade partners driven by geopolitical disruptions.

1. The price–volume divergence: more value from less material

The most striking feature of the 2015–2025 period is a fundamental decoupling between the monetary value of trade and the physical quantities exchanged. Both exports and imports grew in value while declining sharply in volume, indicating that the EU is exporting and importing fewer tonnes but at significantly higher prices.

1.1. Exports: volume down by over a quarter, prices up by half

EU exports tell a clear two-speed story. Export value rose from €244.4 million in 2015 to €267.8 million in 2025 (+9.6%), but export volume fell from 119,578 tonnes to 86,557 tonnes (−27.6%). The average unit export price consequently surged from €2,043/t to €3,092/t (+51.3%).

1.2. Imports follow a similar, though less pronounced, trajectory

EU imports rose from €113.0 million to €126.1 million (+11.6%) while volume edged down from 36,080 to 34,108 tonnes (−5.5%). The average import unit price climbed from €3,132/t to €3,696/t (+18.0%). Import prices started at a higher base than export prices and remain elevated in 2025, reflecting the premium attached to specialised or high-specification inbound materials.

1.3. The EU's production base grew in value even faster

Domestic EU production volumes grew modestly (from 1,002,019 t to 1,050,000 t, or +4.8%), but production value exploded from €586.7 million to €1,480.6 million (+152.3%). This confirms that the price surge visible in trade data reflects a genuine, sector-wide cost and price escalation rather than a compositional shift toward higher-value products. Raw material costs, energy prices, and inflationary pressures in the construction supply chain likely drove this transformation.

2. Geopolitical shocks and the reshaping of the EU's trade geography

The decade saw a dramatic reconfiguration of the EU's partner landscape, most visibly through the near-total collapse of trade with Russia and the rapid rise of China and Türkiye as import sources.

2.1. Russia: from active partner to near-zero

The most dramatic single shift concerns the Russian Federation. EU exports to Russia fell from €13.5 million in 2015 to just €7,003 in 2025 (−99.9%), while imports from Russia collapsed from €679,572 to €14,995 (−97.8%). This near-total cessation of bilateral trade in mineral insulating materials aligns precisely with the EU sanctions regime imposed following Russia's invasion of Ukraine in 2022. The volatility data confirms the disruption: Russia shows a coefficient of variation of 0.90 on imports and 0.67 on exports — among the highest of all partners.

2.2. China and Türkiye emerge as key import suppliers

China's share of EU imports surged from €12.7 million to €33.5 million (+165.0%). Türkiye's rise is even more striking in percentage terms: imports from €912,893 to €4.3 million (+370.5%). These two countries have partially filled supply gaps left by the Russian disruption and reflect a broader trend of EU diversification toward Asian and near-shore suppliers.

2.3. The UK and Switzerland remain pillars, Ukraine gains prominence

The United Kingdom remained the EU's largest single export destination throughout the period (€51.9 million in 2025, down from €60.5 million in 2015, or −14.2%). Switzerland grew to become the second-largest export market (€28.9 million, +44.8%). Ukraine, despite the ongoing conflict, saw exports increase from €3.8 million to €8.2 million (+114.7%), likely reflecting reconstruction-related demand and closer EU integration. Conversely, the United States absorbed €52.2 million of EU exports in 2025 (+55.1%), underscoring the transatlantic commercial relevance of this product category.

2.4. Import concentration has fallen markedly

The Herfindahl–Hirschman Index (HHI) for import value fell from 2,772 in 2015 to 1,912 in 2025 (−31.0%). This decline signals a meaningful diversification of the EU's import sources — from a market historically concentrated around Japan and the United Kingdom toward a broader basket that now includes China, the United States, and Türkiye. For exports, the HHI remained broadly stable (1,020 → 1,014), reflecting the enduring dominance of the UK and US markets.

3. EU internal dynamics: shifting centres of production and trade

The EU's internal geography of this sector evolved considerably, with Central and Eastern European countries gaining prominence as both producers and exporters.

3.1. Germany's export dominance erodes but remains substantial

Germany was by far the EU's largest exporter in both 2015 (€129.7 million, 53.1% of total) and 2025 (€107.9 million). However, its share declined as other Member States expanded their export capacity. Belgium (+35.1%), Hungary (+37.3%), France (+217.4%), and Poland (+94.0%) all posted strong export growth over the decade.

3.2. Specialisation confirms the CEE production cluster

Specialisation indices for 2025 reveal that Central and Eastern European countries are disproportionately specialised in this product category. Hungary leads with an RSCA of 0.49, followed by Belgium (0.36), Czechia (0.35), and Slovenia (0.33). At the opposite end, Finland (RSCA −0.99), Slovakia (−0.98), and Greece (−0.91) show virtually no specialisation. This pattern suggests the emergence of a regional production corridor in the Visegrád and Benelux countries, likely driven by proximity to raw materials, cost advantages, and established building-materials industrial bases.

3.3. Import patterns: Italy and Poland join the top tier

On the import side, Germany's share collapsed from €48.4 million to €16.0 million (−66.9%), while Italy (+167.6% to €12.5 million), Poland (+165.0% to €15.6 million), and Ireland (+790.1% to €13.9 million) all surged. These shifts suggest that construction booms or industrial demand in these countries drove increased reliance on external suppliers — a pattern consistent with the EU's broader internal market integration.

Conclusion

The EU market for CN 680690 mineral insulating materials over 2015–2025 is best understood through three lenses: price inflation, geopolitical reorientation, and internal rebalancing.

First, unit prices have risen dramatically — +51% for exports and +18% for imports — even as physical volumes contracted. This price–volume divergence reflects broader cost pressures in energy-intensive mineral processing and the construction supply chain.

Second, the trade geography has been redrawn by geopolitics. The collapse of EU–Russia trade in this sector (−99.9% for exports, −97.8% for imports) is the single largest structural shift of the decade, accelerating a pre-existing diversification trend. China and Türkiye have stepped in as alternative import suppliers, while the UK and US have remained the EU's anchor export markets.

Third, the EU's internal landscape has evolved: Germany's dominance has eroded, making room for Belgium, Hungary, France, and Poland to claim larger shares of both exports and imports. The EU remains a net exporter of these materials, with a persistent positive trade balance (€142 million in 2025) and a negative net import reliance of −11.9%, indicating structural autonomy. Export propensity has grown (18.6% → 20.0%), signalling that the sector has become more outward-facing even as production volumes remained largely flat.
