Market evolution: Cobalt oxides and hydroxides (CN 2822) — 2015–2025

Introduction

This report examines the trade dynamics of cobalt oxides and hydroxides (CN 2822) by the European Union with non-EU countries over the period from 2015 to 2025. The analysis covers key metrics including trade values, volumes, partner concentration, and strategic autonomy indicators. The data reveals a transformative decade for the EU's position in this critical market, characterized by a dramatic surge in export performance and a fundamental shift in its trade balance. The subsequent sections interpret these trends, focusing on the evolution of trade volumes and values, the restructuring of partner networks, and the implications for the EU's market structure and strategic vulnerability.

1. From Importer to Exporter: The EU's Dramatic Trade Reversal

The period 2015–2025 witnessed a complete reversal in the EU's trade posture for cobalt oxides and hydroxides. The bloc transformed from a net importer into a significant net exporter, driven by an unprecedented expansion of outbound shipments.

Export growth far outpaced import increases

EU exports of CN 2822 experienced explosive growth, both in value and quantity, vastly exceeding the growth in imports.

While import values and quantities grew moderately (by 38.6% and 32.8% respectively), exports surged by over 2,000% in value and nearly 3,000% in volume. This asymmetry fundamentally altered the EU's trade balance.

The EU became a consistent net exporter

The dramatic export growth propelled the EU from a net import position to a strong net export position. The trade balance shifted from a deficit of -€15.4 million in 2015 to a surplus of €48.5 million in 2025, a change of +413.9%. This is further confirmed by the net import reliance metric, which moved from +15.8% (indicating import dependence) to -43.7% (indicating net export status). The EU's production capacity, while declining slightly in quantity (-22.0%), became increasingly oriented towards servicing international markets rather than domestic demand alone.

2. Restructuring Partnerships and Volatile Supply Chains

The transformation in trade volumes was accompanied by significant shifts in the EU's trade partner networks for CN 2822, characterized by diversification in exports and increased volatility in key import relationships.

Export partners diversified away from historical leaders

EU export flows became much more distributed among partners, while import sources remained concentrated but with volatile individual relationships.

Exports shifted dramatically towards Asia (South Korea, Japan, India) and North America (United States), with these partners seeing astronomical percentage growth from very low bases. This diversification is reflected in a sharp drop in the export Herfindahl-Hirschman Index (HHI), from 4,038 in 2015 to 1,344 in 2025, indicating a much less concentrated export market.

Import sources showed high volatility and concentration

On the import side, the EU's sourcing became more concentrated (HHI increased from 4,641 to 5,519) and exhibited extreme volatility with some partners. While China and the United Kingdom remained the primary sources, the volatility coefficients for many partners were very high. For instance, the Democratic Republic of Congo's imports fell from €34.7 million to €114, while Qatar's surged from €53 to €2.97 million. Significant price shocks were detected in 2017 for imports from both China and the United Kingdom, with abnormal price spikes of 95.8% and 84.9% respectively, suggesting episodes of supply tightness or cost pressure.

3. Internal Market Reorganization and Strategic Implications

The surge in exports was not uniform across the EU, leading to a reorganization of internal specialisation and raising new questions about the bloc's strategic position in the global cobalt value chain.

Specialisation became highly concentrated in Belgium

In 2025, the EU's export capacity for CN 2822 was overwhelmingly concentrated in one member state.

Belgium was the only member state with a strong revealed comparative advantage (RSCA > 0) in 2025, responsible for the vast majority of EU production. However, the Netherlands had a larger share of total EU exports, suggesting it acts as a major trade and logistics hub for the product. This concentration indicates a high dependency on Belgium's production ecosystem for the EU's export competitiveness.

Export propensity skyrocketed, highlighting market integration

The most dramatic change in the EU's market profile was the explosion of its export propensity, which measures the share of EU production that is exported. It jumped from a negligible 3.7% in 2015 to 44.8% in 2025 (+1,102.5%). This indicates that the EU's cobalt oxide production is now deeply integrated into global supply chains, primarily serving foreign markets rather than the EU internal market. This integration creates exposure to global demand fluctuations but also signifies the EU's emergence as a key supplier to downstream battery and chemical industries worldwide.

Conclusion

Over the 2015–2025 decade, the EU's trade in cobalt oxides and hydroxides underwent a fundamental transformation. The bloc evolved from a net importer to a major net exporter, with export values and volumes growing at extraordinary rates. This shift was fueled by a successful diversification of export partnerships across Asia and North America, alongside a reorganization of internal production towards highly specialised and export-oriented hubs, predominantly in Belgium. However, this success is accompanied by vulnerabilities: import supply chains remain volatile and concentrated, and the EU's newfound export competitiveness is heavily reliant on a single member state's production capacity. The dramatic rise in export propensity confirms the sector's deep integration into global markets, making it a strategically significant component of the EU's industrial and trade portfolio.
