Market evolution: Warships and other vessels (CN 8906) — 2015–2025

Introduction

Combined tariff heading 8906 covers a heterogeneous set of vessels — from warships and naval patrol craft to lifeboats, patrol boats, and other specialised vessels not classified under headings 8901 to 8905. As a residual heading, it captures an unusually wide range of products whose unit values, volumes, and trade patterns vary enormously. The European Union has consistently maintained a significant trade surplus in this category throughout 2015–2025, yet the composition, geographic orientation, and magnitude of that surplus have shifted markedly. This report analyses EU extra-EU trade flows in CN 8906, disaggregated by its two sub-headings — warships (890610) and other vessels (890690) — to uncover the main dynamics behind what are often headline-grabbing but structurally lumpy trade flows. Data are drawn from the general overview dashboard.

1. The Warship Effect: How Defence Contracts Drove EU Export Volatility

1.1 EU exports surged and receded with warship delivery cycles

Over the full period, total EU exports of CN 8906 fell from EUR 859 million in 2015 to EUR 489 million in 2025 (−43%). However, this headline decline conceals enormous intra-period swings. Exports peaked at approximately EUR 1,181 million in 2022 before falling back sharply. The pattern is almost entirely explained by the warship sub-heading (890610), which accounted for virtually all the variation:

Warship export values ranged from less than EUR 1 million in 2019 to EUR 914 million in 2022 — a swing of three orders of magnitude. This is characteristic of the defence procurement cycle: major naval contracts are fulfilled in discrete delivery batches rather than flowing steadily.

1.2 The non-warship segment declined through the early 2020s before recovering

Excluding warships, the "other vessels" sub-heading (890690) — comprising lifeboats, patrol craft, and miscellaneous vessels — followed its own trajectory. Export value rose from EUR 726 million in 2015 to a peak of EUR 990 million in 2017, then declined to a trough of EUR 226 million in 2021 (−77% from peak). A partial recovery brought exports back to EUR 486 million by 2025, still below the 2015–2017 level. The tonnage of 890690 exports tells a similar story of contraction: from 6,943 tonnes in 2015 to a low of 1,209 tonnes in 2024, with the unit price rising from EUR 16,522/t to EUR 58,455/t — suggesting a compositional shift toward higher-value, lower-volume vessels.

1.3 Import growth was driven by a single year's anomaly and by the warship segment

EU imports of CN 8906 grew 27% over the period (EUR 154 million → EUR 196 million), but the path was irregular. The import peak of EUR 599 million occurred in 2017, driven almost entirely by the 890690 sub-heading, which recorded values of EUR 597 million that year before dropping back. Warship imports (890610) remained negligible in most years but spiked to EUR 66 million in 2023 and EUR 47 million in 2025, coinciding with deliveries reported by Romania and other Eastern European importers.

2. Shifting Geographies: Traditional Partners Losing Ground to New Entrants

2.1 Export destinations became more fragmented and less predictable

The EU's top export partners changed substantially between 2015 and 2025:

Indonesia's collapse from the EU's single largest 8906 export destination in 2015 (EUR 164 million) to virtually zero by 2025 almost certainly reflects a one-off naval or patrol-vessel delivery that year. Norway, long a stable partner for maritime equipment, still accounts for meaningful volumes but has declined from EUR 147 million to EUR 43 million. The United Kingdom, by contrast, surged from EUR 7 million to EUR 70 million — a near-tenfold increase — likely reflecting post-Brexit defence cooperation and procurement patterns. The UK shock event detected in 2020 (267.6% price shift, 30.6% value share) underscores how rapidly this bilateral trade can move in a single year.

2.2 Import sources diversified, with China rising sharply

On the import side, the most striking trend is China's emergence:

China's imports grew from EUR 3 million to EUR 30 million over the period — and peaked at EUR 338 million in 2017 (the same year as the overall import peak), suggesting occasional very large deliveries of non-warship vessels. Norway remains the EU's most stable import partner at nearly EUR 48 million in 2025, consistent with its deep maritime-industrial base. The decline in Korean imports (−97%) is consistent with a pattern of sporadic, project-based deliveries rather than ongoing trade.

2.3 Internal EU specialisation shifted toward Eastern Mediterranean and Baltic producers

The specialisation analysis for 2025 reveals that the most specialised EU exporters of CN 8906 are small to mid-sized maritime nations:

Meanwhile, large economies such as Belgium (RSCA −1.00), Germany, and France are net unspecialised in this heading — they import far more than their export share would suggest. The prominence of Cyprus and the Baltic states likely reflects their roles as flag-of-convenience registries (for Cyprus) and niche shipbuilders (for the Baltics), rather than large-scale production.

Among EU member-state reporters, the most dramatic internal shifts on the export side include:

• Romania: EUR 34 million → EUR 111 million (+224%), becoming the EU's largest exporter by 2025
• Spain: EUR 14 million → EUR 96 million (+606%), a sharp upward trajectory
• Netherlands: EUR 178 million → EUR 18 million (−90%)
• France: EUR 139 million → EUR 2 million (−99%)

These shifts suggest a reorientation of EU naval and vessel production toward lower-cost shipyards in Southern and Eastern Europe, offsetting declines in traditional Western European producers.

3. Extreme Volatility and Thin-Market Dynamics

3.1 Trade in CN 8906 is structurally lumpy and unpredictable

The volatility analysis confirms the impression of a highly erratic market. Coefficients of variation (CV) for bilateral flows are exceptionally high:

• Most volatile import partners: China (CV 3.15), Australia (3.09), Korea (2.76)
• Most stable import partners: Türkiye (0.58), Norway (0.72)
• Most volatile export partners: Malaysia (3.13), Iceland (2.83), Indonesia (2.81)
• Most stable export partners: United Kingdom (0.65), Norway (0.68)

These figures far exceed typical CVs in manufactured-goods trade, reflecting the fact that a single vessel delivery can dominate an entire year's bilateral flow.

3.2 Detectable shock events confirm the role of singular large transactions

Three major shock events were identified:

The Indonesia shock in 2020 — a 26-fold price increase — almost certainly reflects a major one-off delivery of high-value vessels (possibly military patrol craft). The UK export shock in the same year, contributing over 30% of total EU export value, is consistent with large naval or coastguard equipment deliveries. The UK import shock in 2021 suggests a reciprocal or independent large procurement event.

3.3 Market concentration is moderate and has slowly declined

The Herfindahl-Hirschman Index (HHI) for import concentration decreased from 2,438 to 2,255 (−7.5%), and for exports from 1,380 to 1,289 (−6.6%). While imports remain in the "moderately concentrated" range, the gradual decline indicates that the EU is sourcing from a somewhat wider set of partners than it did in 2015. The export side is less concentrated and became more so over the period, consistent with the diversification of delivery destinations away from a handful of large one-off contracts.

Conclusion

EU trade in CN 8906 between 2015 and 2025 was dominated by three overarching dynamics. First, warship deliveries (sub-heading 890610) introduced extraordinary volatility into total export values, which swung from under EUR 400 million to over EUR 1.1 billion depending on the timing of large defence contracts. Second, the geographic structure of trade shifted meaningfully: traditional partners like Norway and the Netherlands lost share, while the United Kingdom, Romania, and Spain gained prominence on the export side, and China emerged as a major import source. Third, the underlying "other vessels" segment (890690) underwent a sustained contraction through the early 2020s before partially recovering, with rising unit values suggesting a move toward higher-specification products. The EU retains a comfortable trade surplus in this heading, but its size fluctuates wildly — currently at EUR 293 million in 2025, down from over EUR 800 million at its peak. Given the defence-investment momentum across several EU member states, the warship sub-heading is likely to generate further large and irregular swings in the years ahead.
