Market evolution: Mica and mica articles (CN 6814) — 2015–2025

Introduction

This report analyzes the evolution of the European Union's trade in worked mica and mica articles (Combined Nomenclature code 6814) from 2015 to 2025. Over this decade, the EU's market position underwent a fundamental transformation. While the value of both imports and exports grew, imports expanded at a dramatically faster pace, shifting the EU from a marginal net importer to a heavily import-dependent market. This analysis delves into the scale of this shift, the changing geographic patterns of trade and their associated risks, and the EU's internal production landscape in the face of these external pressures.

The EU’s Dramatic Shift to Net Import Reliance

The most striking feature of the decade is the EU's ballooning trade deficit and associated import dependency. The bloc's trade position deteriorated significantly, driven by a surge in import volumes and values that far outpaced export growth.

• Trade Balance: The EU's trade balance in mica products swung from a deficit of €4.5 million in 2015 to a deficit of €82.8 million in 2025. This represents a deterioration of over 1,700% over the period.
• Import Growth: Import values increased by 218% (from €40.5 million to €128.8 million), while import quantities grew by 150% (from 4,650 to 11,644 tonnes). This indicates both higher volumes and rising prices.
• Net Import Reliance: The EU's net import reliance surged from 21.7% in 2015 to 68.1% in 2025, meaning that nearly seven out of every ten euros spent on mica products in the EU went to foreign suppliers by the end of the period.

Geographic Concentration, Volatility, and Supply Chain Risks

The structure of the EU's mica trade became more geographically concentrated on the import side, creating potential vulnerabilities, while export partnerships remained more diversified but exposed to price shocks.

China's Dominance and Rising Import Concentration

China emerged as the overwhelmingly dominant supplier to the EU, leading to a sharp increase in market concentration.

• China's Share: EU imports from China surged by 667% in value, from €10.8 million in 2015 to €83.2 million in 2025. This single country accounted for 64.6% of total EU mica import value by the end of the period.
• Concentration (HHI): This growth in China's share is reflected in the Herfindahl-Hirschman Index (HHI) for import concentration, which rose by 76.5% from 2,502 to 4,417. An HHI above 2,500 typically indicates a highly concentrated market, signaling increased supply chain risk.
• Traditional Partners: While Switzerland remained a stable, high-value supplier (around €15-17 million annually), other partners like Russia saw their import value decline by 62%, contributing to the overall concentration toward China.

Export Market Diversification and Price Volatility

EU exports, though growing slower than imports, served a more diverse set of partners but were not immune to market shocks.

• Diversified Partners: The EU's top seven export partners included major economies like the US, UK, and China, as well as neighbors like Switzerland, Serbia, and Türkiye. The export HHI remained relatively low and stable.
• Price Shocks: Despite diversification, the EU experienced significant price shocks in key export markets. Notably, export prices to the United States spiked by 89.2% in 2022, a major anomaly. Similar, though less severe, price jumps occurred in exports to the UK and Russia in 2023, indicating periods of intense pricing pressure or supply-demand mismatches.
• Volatility: Import streams from China and Russia exhibited the highest volatility (Coefficient of Variation >0.5), suggesting less predictable supply, while exports to most partners showed lower volatility.

EU Production and Specialization Under Pressure

Against the backdrop of surging imports, the EU's domestic production of mica articles showed signs of strain, although certain member states maintained strong export-oriented specializations.

Declining Domestic Production

Data on EU production (PRODCOM) reveals a contraction in both volume and value over the period.

• Production Value: Estimated production value declined by 30.3%, from €43 million in 2015 to €30 million in 2025 (with significant fluctuations in between).
• Production Quantity: The quantity produced fell by 3.1% from 3.82 million kg to 3.71 million kg. The divergence between the sharper drop in value and the more modest drop in quantity points to possible pricing pressures or a shift in the product mix.

Resilient Export Specializations in Key Member States

Despite overall production declines, several EU member states demonstrated strong competitive advantages in exporting mica products.

• Specialization Leaders: In 2025, Slovenia (RSCA: 0.78) and Austria (RSCA: 0.71) had the highest Revealed Symmetric Comparative Advantage (RSCA), indicating strong export specialization relative to their overall trade.
• Major Exporters: Austria was the leading EU exporter by value, with exports growing by 75% to €18.6 million. Germany followed, growing by 65% to €11.4 million. These countries appear to have successfully oriented their production towards higher-value or niche export markets.
• Importing Producers: Notably, Germany and Austria were also among the top EU importers. This suggests the existence of integrated regional supply chains, where these countries import raw or semi-processed mica (potentially from China or Switzerland) for further processing and re-export, both within and outside the EU.

Conclusion

The period 2015–2025 was characterized by a fundamental restructuring of the EU market for mica articles. The bloc became substantially more reliant on imports, with China solidifying its position as the dominant supplier, leading to a highly concentrated and potentially vulnerable import structure. While the EU maintained a diversified export market and specialized production hubs in Austria, Germany, and Slovenia, domestic production value declined. The combination of soaring import dependency and concentrated sourcing presents clear strategic challenges for the EU's mica supply chain, even as its export sector showed resilience and capacity for value addition. The market has evolved from one of near-balance to one defined by a significant and growing structural deficit.
