Market evolution: Navigational instrument parts (CN 901490) — 2015–2025

Introduction

This report examines the evolution of European Union trade in parts and accessories for compasses and other navigational instruments (Combined Nomenclature code 901490) over the period 2015–2025. The analysis draws on trade data and market indicators covering EU imports from and exports to non-EU countries, production figures, concentration measures, and vulnerability indicators. The period under review encompasses several structurally significant developments: the maturation of satellite-navigation technology, the disruption of global supply chains during the COVID-19 pandemic, the United Kingdom's departure from the EU single market, and a broader geopolitical reorientation of trade flows. The following three sections identify the most salient dynamics and interpret them in light of these contextual factors.

1. A gradual erosion of the EU's trade surplus driven by diverging import and export trajectories

1.1. EU exports fell in both value and volume while imports trended upward

The headline story of the 2015–2025 decade is one of divergence. EU exports declined from €394.9 million in 2015 to €310.6 million in 2025, a contraction of −21.3 % in value. The decline in physical volume was steeper still: exported tonnage fell from 675.9 tonnes to 472.3 tonnes (−30.1 %). By contrast, EU imports rose from €259.4 million to €286.4 million (+10.4 %), with quantities climbing from 549.3 tonnes to 594.9 tonnes (+8.3 %).

The consequence for the EU's trade balance has been dramatic. The surplus shrank from €135.5 million to just €24.2 million (−82.1 %), and at its trough in 2023 the EU even recorded a deficit of −€41.5 million. Although a modest surplus reappeared by 2025, the structural shift is unmistakable: the EU moved from a comfortable net-exporter position to near-balance.

1.2. Unit prices rose on both sides, signalling a move up the value chain

A closer look at unit values reveals that the decline in export quantity was not simply a loss of low-margin business. Average export prices increased from €581,949/t in 2015 to €656,199/t in 2025 (+12.8 %), with an even higher peak of €933,470/t recorded in between. Import prices followed a similar upward trajectory, rising from €471,981/t to €480,831/t (+1.9 %). The fact that export prices have consistently remained well above import prices (roughly €656,000 vs. €481,000 per tonne in 2025) indicates that the EU specialises in higher-value segments of the navigational-instrument-parts market, even as overall volumes decline.

1.3. Domestic production contracted sharply, reinforcing the import trend

Available production-value data show EU output falling from €924.6 million to €480.0 million (−48.1 %), with a trough at €379.4 million. This near-halving of production is consistent with the observed decline in export volumes and helps explain why the EU's export propensity (exports as a share of production) actually rose from 34.4 % to 82.4 %: a shrinking production base can appear more "export-oriented" simply because domestic demand is increasingly met by imports rather than domestic output.

2. A structural reorientation of trade partners: the rise of Asian suppliers and the retreat from traditional Atlantic flows

2.1. The United States and the United Kingdom lost ground on both the import and export sides

The two largest individual-country trade partners — the United States and the United Kingdom — experienced contrasting evolutions over the decade. EU exports to the United States fell from €120.9 million to €66.6 million (−44.9 %), while exports to the United Kingdom declined from €86.3 million to €40.5 million (−53.1 %). Together, these two destinations accounted for roughly half of EU exports in 2015 but contributed only about a third by 2025.

On the import side, US-sourced parts grew from €99.9 million to €131.9 million (+32.0 %), making the United States an even larger supplier. By contrast, imports from the United Kingdom fell from €36.4 million to €24.4 million (−32.8 %), likely reflecting the post-Brexit trade friction that emerged after 2020. The UK's share of EU imports thus contracted, despite the country's historically strong maritime-navigation industry.

2.2. China, Japan, and Mexico emerged as fast-growing import sources

Several Asian and Latin American partners registered striking growth rates on the import side:

Mexico's growth, starting from a very small base, likely reflects the integration of Mexican assembly operations into multinational supply chains. The near-doubling of both Japanese and Chinese imports points to the growing competitive strength of Asian manufacturers in mid- and high-precision navigational components.

2.3. EU exports diversified geographically, with China and Türkiye gaining weight

While the traditional Atlantic partners lost share in EU exports, two countries stood out for their rapid growth:

This geographic diversification is confirmed by the fall in the export-side Herfindahl-Hirschman Index (HHI), which dropped from 1 560 to 907 (−41.8 %). The EU's export market for navigational parts has become markedly less concentrated — a sign of healthier diversification. On the import side, however, the HHI rose from 1 914 to 2 404 (+25.6 %), indicating that sourcing has become somewhat more dependent on a smaller number of suppliers, principally the United States.

2.4. Within the EU, France and Germany saw the steepest export declines while the Netherlands gained ground

At the member-state level, the distribution of export activity shifted noticeably:

France and Germany — historically the two largest exporters — each lost roughly half their export value. The Netherlands, benefiting from its role as a logistics hub, and Czechia, likely serving as an assembly and re-export platform for multinational firms, more than compensated in relative terms. This intra-EU rebalancing is consistent with the broader trend of production shifting toward Central and Eastern Europe.

3. Increased market openness coexists with rising strategic vulnerability

3.1. Trade intensity and export propensity surged to record highs

The vulnerability indicators paint a picture of an economy that is increasingly entwined with global markets in this product category:

Trade intensity (the sum of imports and exports as a share of production) nearly doubled, rising from 50.1 % to 89.8 %. Export propensity — the share of domestic output shipped abroad — more than doubled. These figures indicate that the EU's navigational-parts sector has become profoundly open to international trade over the decade.

3.2. The net import reliance metric signals a shift from mild self-sufficiency toward dependency

Net import reliance measures how much of domestic demand is met by imports. The indicator remained negative throughout the period (indicating the EU was a net exporter), but it deteriorated from −3.1 % in 2015 to −9.6 % in 2025, meaning the surplus capacity shrank. At its worst point the figure reached −66.5 % — an extraordinary reading that likely reflects a temporary collapse of exports during the 2020–2021 pandemic disruption. Although this extreme value proved transitory, the underlying trend is clear: the EU's margin of self-sufficiency in navigational-parts production is narrowing.

3.3. Price volatility and isolated supply shocks underline sector-specific risks

The volatility analysis reveals that certain trade corridors are significantly more volatile than others. On the import side, Morocco (CV = 1.31) and Singapore (CV = 1.45) displayed extreme variability, suggesting episodic or project-driven procurement. On the export side, Japan (CV = 0.93) stands out for its pronounced swings.

The detection of price shocks further highlights specific risk events:

The clustering of anomalous export-price events in 2018–2019 — before the pandemic — may reflect either one-off large-value contracts (e.g., defence or maritime equipment orders) or shifts in product mix toward higher-specification components. These episodes, while not indicative of structural disruption, illustrate the sector's susceptibility to large, lumpy orders.

3.4. Italian and German manufacturers maintain the strongest competitive specialisation

The specialisation data for 2025 confirm that competitive strength in navigational-parts production is concentrated in a handful of member states:

Italy leads with a Revealed Symmetric Comparative Advantage (RSCA) of 0.51, implying a strong and persistent specialisation. Germany and the Netherlands also display clear comparative advantages (RCA > 1). By contrast, most Central and Southern European member states — Romania, Portugal, Ireland, Poland — show RSCA values close to −1, indicating virtually no involvement in the production of these components. The concentration of know-how in a few Western European countries constitutes a structural feature of the sector and a potential vulnerability should geopolitical disruptions affect those specific supply lines.

Conclusion

Over the 2015–2025 decade, the EU market for navigational-instrument parts (CN 901490) underwent a significant structural transformation. The EU's position as a net exporter weakened considerably, with the trade surplus shrinking by 82 % and production value nearly halving. Exports declined in both volume and value, although rising unit prices suggest a shift toward higher-value-added products. At the same time, imports grew modestly, with fast-rising contributions from Japan, China, and Mexico.

Geographically, trade flows have been reoriented away from the traditional US and UK corridors and toward a more diversified set of partners — a trend visible on both the import and export sides. The resulting decline in export concentration (HHI) is a positive signal for resilience, but the simultaneous increase in import concentration warrants monitoring.

The most consequential long-term trend is the sharp rise in trade intensity and export propensity, which reflects both a shrinking domestic production base and a deepening integration into global value chains. While this openness can bring efficiency gains, it also exposes the EU to supply-chain shocks and price volatility, as illustrated by the extreme reliance readings during the pandemic years. Policymakers concerned with strategic autonomy in maritime and aerospace navigation will find in these data a clear case where European industrial capacity has contracted, while demand — and dependency — has grown.
