Market evolution: Parts and accessories for weapons (CN 9305) — 2015–2025

Introduction

This report analyzes the evolution of European Union (EU) trade in parts and accessories for weapons (Combined Nomenclature code 9305) between 2015 and 2025. The analysis is based on official trade data covering imports to and exports from the EU with non-EU partners. Over this period, the market has undergone significant expansion and structural shifts, characterized by robust growth in both trade flows, a changing composition of key partners, and a marked increase in the EU's import dependency for certain high-value segments. These dynamics reflect broader geopolitical and security trends impacting the global arms industry.

The Great Rebalancing: From Net Exporter to Import Reliant

The decade was defined by a fundamental shift in the EU's trade position for weapon parts, moving from a comfortable net exporter to a state of near equilibrium and growing import reliance. This rebalancing was driven by import growth significantly outpacing export growth.

Aggregate Trade Flows Show Explosive Growth

Both EU exports and imports of CN 9305 products expanded substantially. However, the rate of growth on the import side was more than double that of exports, leading to a erosion of the trade surplus.

The EU's net import reliance flipped from -25.9% (a surplus) in 2015 to +5.5% (a slight deficit) in 2025. This indicates a growing structural dependency on non-EU suppliers for meeting regional demand.

Price Dynamics Amplified the Shift in Value

The value increase was not solely due to higher volumes; a significant rise in average unit prices (value per tonne) also played a critical role, especially for imports.

The price of imported parts more than doubled, suggesting the EU is increasingly importing more sophisticated, higher-value components (e.g., for military systems) or facing inflationary pressures in global supply chains.

A Shifting Geopolitical Landscape: Partners and Internal Champions

The network of trading partners for the EU in this sector has transformed, with both the origins of imports and the destinations of exports becoming more diversified yet concentrated around key strategic players.

The United States Remains the Keystone, but New Partners Emerge

The United States is overwhelmingly the EU's largest partner in both directions, but its dominance is being challenged on the import side by the rapid rise of other nations.

South Korea's explosive growth as an import source is the most notable trend. Similarly, imports from the United Kingdom surged post-Brexit. This diversification reduces single-source dependency but increases complexity.

Within the EU: Poland and Sweden Rise as Key Hubs

The distribution of imports within the EU has also changed dramatically. Poland has transformed from a minor player into the bloc's largest single importer, likely driven by military modernization and its role as a logistics hub.

On the export side, Sweden has seen remarkable growth, increasing its exports by 417% to become the third-largest EU exporter by 2025. This aligns with its role in European defense initiatives.

Segment Analysis: Military Parts Drive the Narrative

The aggregated product code 9305 masks divergent trends across its four sub-categories. The data reveals that parts for military weapons have been the primary engine of trade growth and volatility.

Military Weapon Parts Dominate Import Value

The sub-category 930591 (Parts for military weapons of heading 9301) saw the most dramatic value increase in imports, becoming the single largest segment.

Evolution of Key Import Segments (Value):

The surge in military parts imports, especially the price spike in 2022, strongly correlates with the post-2022 geopolitical environment and accelerated rearmament within Europe.

Export Composition Remains More Balanced, with a Military Tilt

While shotgun/rifle parts (930520) remain the largest export category by value, exports of military weapon parts (930591) also grew significantly.

The 253% increase in exports of military weapon parts highlights the EU's growing capacity and role as a supplier in this segment, albeit one that is now also a major consumer.

Conclusion

The 2015–2025 period represents a transformative decade for the EU's trade in weapon parts (CN 9305). The market evolved from one of relative self-sufficiency into a high-growth, import-intensive sector, fundamentally altering the EU's trade balance. This shift was primarily fueled by surging demand for parts for military weapons, driven by heightened security concerns and rearmament.

Geographically, the traditional transatlantic axis with the United States remains central, but significant new import dependencies have emerged, particularly with South Korea and, post-Brexit, the United Kingdom. Within the EU, defense spending surges have turned Poland into the largest single market for these imports. Concurrently, the export base has diversified, with Sweden establishing itself as a major exporter.

The market's structure now reflects a strategic paradox: the EU is simultaneously strengthening its position as an exporter of certain weapon systems while becoming critically dependent on non-EU suppliers for essential military components. This dual dynamic underscores the interconnectedness and vulnerabilities of modern defense industrial supply chains.
