Market evolution: Aluminium electrolytic capacitors (CN 853222) — 2015–2025

Introduction

This report analyses the European Union's external trade in fixed aluminium electrolytic capacitors (customs code 853222) over the 2015–2025 period. The data reveals a market characterized by rising export values and intensifying import reliance, with significant structural shifts in trade partnerships and production within the EU. The following sections break down the principal dynamics shaping this critical component of the electronics supply chain.

1. Rising export value amidst persistent structural import dependence

Over the 11-year period, the EU's trade balance for aluminium electrolytic capacitors remained negative, indicating persistent net import reliance. However, the overall trajectory shows a significant strengthening of the EU's export position.

1.1. Robust export growth significantly outpaces import growth

EU exports of these capacitors nearly doubled in value, growing by 90.9% from €123.5 million in 2015 to €235.8 million in 2025. In contrast, import values grew more moderately by 14.0%, rising from €424.9 million to €484.5 million. This faster pace of export growth is also reflected in price trends; the average export price per tonne increased by 48.7%, compared to a 21.2% rise in import prices, suggesting the EU may be moving towards higher-value product niches.

1.2. The trade deficit narrowed, but import reliance deepened

Despite the improving trade balance (deficit reduced by 17.5%), the EU's net import reliance on the rest of the world, as a percentage of apparent consumption, increased substantially. It rose from 40.9% in 2015 to 60.2% in 2025, a jump of 47.1%. This indicates that while exports are growing, the domestic market's consumption is increasingly met by foreign production.

2. Shifting partnership landscapes and increasing supply concentration

The geographic concentration of both import and export flows has evolved, highlighting changing sourcing strategies and export opportunities for the EU.

2.1. Imports: Japan and China cement dominance as supplier landscape diversifies

Japan remained the EU's largest supplier, increasing its import share value by 27.7% to €197.5 million. However, China showed the most dramatic growth, with its imports surging by 87.1% to reach €141.7 million in 2025. Meanwhile, imports from traditional Southeast Asian partners like Malaysia (-27.9%), Thailand (-61.2%), and notably the United Kingdom (post-Brexit, -83.6%) declined sharply. The Herfindahl-Hirschman Index (HHI) for import concentration increased by 36.2%, confirming a consolidation around fewer key suppliers.

2.2. Exports: Destinations diversify, with the United States becoming the top market

Export flows became more diversified, as shown by a 32.2% decrease in the export HHI. The United States emerged as the primary destination, with exports growing by 164.9% to €46.9 million. Significant growth was also recorded for China (+114.6%), Mexico (+131.5%), and India (+76.2%). The United Kingdom, though still the second-largest market, saw its share decline by 27.3%.

3. EU production collapse drives specialization and export volatility

A dramatic contraction in EU-based production has fundamentally altered the market structure, influencing member states' roles and creating price volatility in key export markets.

3.1. A collapse in EU production volumes

EU production of these capacitors plummeted, with reported quantity falling by 93.1% from over 4.3 billion items in 2015 to just 300 million in 2025. Production value decreased by 17.9% over the same period. This severe contraction in output capacity is a primary factor behind the increased net import reliance noted earlier.

3.2. Germany and Hungary consolidate their specialized export roles

Within the EU, production and export specialization are highly concentrated. In 2025, Germany (RCA 1.90) and Hungary (RCA 3.41) were the most specialized member states in this product category, together accounting for the majority of EU export value. Germany's exports alone grew by 92.8% to €84.8 million, reinforcing its role as the bloc's manufacturing hub for these components.

3.3. Price shocks in emerging export markets signal transaction volatility

Volatility analysis reveals significant price shocks in EU exports to several growing markets. Most notably, exports to Türkiye exhibited an extreme price abnormality of 52.1 in 2018, with a year-on-year price shift of +127.1%. Similar, though less severe, price shocks were detected in exports to Ukraine (2018) and Mexico (2019). These events suggest high price sensitivity and potential transactional instability in these developing trade relationships.

Conclusion

Over 2015–2025, the EU market for aluminium electrolytic capacitors underwent a profound structural shift. The bloc has become far more reliant on imports, driven by a catastrophic decline in domestic production. Concurrently, the EU has successfully expanded and diversified its export portfolio, moving into higher-value segments and strengthening ties with the US and Asian markets. This has resulted in a more integrated but vulnerable market structure: the EU is a larger player in global trade flows, yet its internal production capacity has diminished, increasing its exposure to external supply risks. The consolidation around key Asian suppliers and the dominance of a few specialized EU member states highlight the strategic dependencies that now define this market.
