Market evolution: Optical fibre cables (CN 854470) — 2015–2025

Introduction

Optical fibre cables (CN 854470) are a strategically important product at the heart of Europe's digital infrastructure ambitions. Over the 2015–2025 period, the EU's extra-EU trade in this product underwent a profound transformation: total trade values nearly doubled, yet the underlying volume and balance dynamics tell a more nuanced story. This report examines the evolution of EU trade flows in optical fibre cables, drawing on customs data from 2015 to 2025. It identifies three main dynamics: a dramatic price-driven surge in trade values that diverges from volume trends, a structural erosion of the EU's net-exporter position, and a significant geographic reorientation of both sourcing and destination markets alongside the emergence of new EU production hubs.

Overview of CN 854470 trade data

1. Prices Drive the Value Surge While Volumes Tell a Different Story

The most striking feature of EU optical fibre cable trade over 2015–2025 is the divergence between the rapid growth in trade values and the stagnation or decline of physical volumes. This price-driven dynamic reshaped both the import and export sides of the market.

Export values surged 73% even as volumes fell 11%

Between 2015 and 2025, EU exports of optical fibre cables grew from €600 million to €1,038 million in value — a 72.9% increase. Over the same period, however, export volumes declined from 50,875 tonnes to 45,154 tonnes (−11.2%). The reconciliation lies in unit export prices, which nearly doubled (+94.8%), rising from €11,793 per tonne in 2015 to €22,971 per tonne in 2025. The peak export value reached €1,255 million, indicating that 2025 was not even the highest year in absolute terms.

Import prices rose more moderately, but volumes grew strongly

EU imports followed a different trajectory. Import values rose 94.5%, from €547 million to €1,063 million, while import volumes grew 40.3% (from 35,055 tonnes to 49,193 tonnes). Unit import prices increased 38.6%, from €15,591 to €21,610 per tonne. Notably, import volumes peaked at 75,258 tonnes before settling, while the minimum volume year saw only 26,837 tonnes — reflecting considerable year-to-year volatility.

The price differential reflects a shift toward higher-value products

A notable pattern is that EU export unit prices, which started 24% below import unit prices in 2015, ended the period 6.3% above them. This reversal suggests that the EU's export basket shifted toward higher-specification or more specialised optical fibre cables — potentially submarine cables, long-haul fibres, or cables with advanced connectors — while imports increasingly covered standard-grade products. This is consistent with the broader industry trend of European manufacturers moving up the value chain.

2. The EU's Net-Exporter Position Has Structurally Eroded

Over the decade, the EU's trade balance in optical fibre cables shifted from a comfortable surplus to near-parity with imports, with a particularly sharp deterioration in the middle of the period.

The trade balance swung from surplus to deficit

In 2015, the EU enjoyed a trade surplus of €53.4 million. By 2025, this had reversed to a deficit of €25.6 million. The swing was even more dramatic in intermediate years: at its worst, the deficit reached €200.4 million, while at its best the surplus climbed to €229.7 million. This instability reflects the interaction of fast-growing imports (driven by fibre-to-the-home rollouts and 5G backhaul demand) with a more volatile export performance.

Net import reliance confirms a structural shift

The net import reliance indicator confirms this erosion. In 2015 the EU was a net exporter (reliance of −11.0%), but the indicator swung to a peak net-import reliance of +12.5% at its worst before settling at −8.9% in 2025. The fact that the EU remains a slight net exporter in value terms in 2025 masks the underlying trend: the margin of self-sufficiency has narrowed considerably, and the product briefly became a net import item.

Trade intensity and export propensity nearly doubled

Two structural indicators underscore the EU's deepening integration into global optical fibre cable trade:

• Trade intensity (exports + imports as a share of production) rose from 41.7% to 73.1% (+75.3%).
• Export propensity (exports as a share of production) increased from 30.0% to 59.3% (+97.9%).

These figures indicate that while EU production has grown (value up 79.8%, from €883 million to €1,588 million; production volumes up 33.0%), the EU has become far more reliant on both exporting and importing to balance supply and demand. The near-doubling of export propensity is particularly telling: European producers are now much more dependent on third-country markets.

3. Geographic Reorientation and the Rise of New EU Production Hubs

The period 2015–2025 saw substantial reshuffling of the EU's trade partners and a notable shift in the intra-EU geography of optical fibre cable production, with Central and Eastern European members gaining prominence.

China dominates imports, but Morocco and India emerged rapidly

On the import side, China remained the EU's largest supplier throughout the period, with import values rising from €182 million to €358 million (+97.3%) and peaking at €532 million. However, the most dramatic growth came from two newer sources:

• Morocco surged from just €231,000 in 2015 to €35.9 million in 2025 (+15,411%), reaching a peak of €66.8 million — reflecting the development of optical cable manufacturing capacity in Morocco, likely linked to nearshoring by European firms.
• India grew from €19.3 million to €47.2 million (+144.8%), peaking at €117.4 million, as Indian manufacturers scaled up fibre cable production for the global market.

The United States remained a significant import source (€114 million → €201 million, +76.6%), while imports from South Korea declined from their peak of €100 million back to €18.2 million.

The US became the EU's fastest-growing export market

On the export side, the United States emerged as a major destination, with EU exports surging from €43.2 million to €185.1 million (+328.7%). Exports to the United Kingdom also nearly doubled from €75.1 million to €185.7 million (+147.1%). Indonesia (+945.1%, from €2.7 million to €27.9 million) and Norway (+90.0%, from €25.8 million to €48.9 million) also showed strong growth. Saudi Arabia, by contrast, saw a slight decline (−8.8%).

Poland and Romania emerged as EU production and export powerhouses

The intra-EU geography of optical fibre cable production shifted markedly eastward. Poland's exports grew from €48.9 million to €174.2 million (+256.1%), making it the third-largest EU exporter by 2025, behind only France and Germany. Romania's growth was even more spectacular in relative terms: from €5.7 million to €69.8 million (+1,123.4%). Both countries exhibit the highest revealed comparative advantage in the EU (RSCA of 0.57 for both), alongside Ireland (0.56).

On the import side, Poland similarly saw the largest growth among EU member states as an importer (+436.7%, from €19.9 million to €106.6 million), while Germany (+217.0%) and the Netherlands (+130.4%) also registered strong increases.

Import concentration eased slightly, but export concentration increased

The Herfindahl-Hirschman Index for import partners by value declined marginally from 1,757 to 1,661 (−5.5%), indicating a modest diversification of sourcing — consistent with the rise of Morocco and India alongside China. By contrast, the export HHI rose significantly from 540 to 965 (+78.6%), suggesting that EU exports became more concentrated on a smaller number of destination markets — primarily the UK and the US.

Volatility was highest with emerging trade partners

Trade with established partners (Türkiye, Switzerland, Norway) showed relatively low volatility (coefficient of variation below 0.3). However, volatility was markedly higher with rapidly growing partners: Morocco (CV 1.02), Indonesia (CV 1.58 for imports; 1.15 for exports), and Canada (CV 1.53 for exports). Several isolated price shocks were detected, notably in exports to Canada (2019, +231% price shift) and Mexico (2023, +208% price shift), likely reflecting one-off large-scale infrastructure contracts rather than sustained market changes.

Conclusion

Over the 2015–2025 decade, the EU's optical fibre cable trade was transformed by three interlocking dynamics. First, a near-doubling of unit prices — particularly on the export side — drove trade values far beyond what volume growth alone would have produced, reflecting the EU's shift toward higher-value-added segments of the fibre cable market. Second, the EU's net-exporter margin narrowed substantially, as strong domestic demand for fibre broadband and 5G infrastructure pulled in growing volumes of imports, especially from China but also from emerging suppliers like Morocco and India. Third, the geographic landscape was redrawn: the US and UK became dominant export markets, while Poland and Romania emerged as major EU production and export hubs, displacing some of the traditional Western European dominance.

Looking ahead, the EU's rising trade intensity (73.1% in 2025) and export propensity (59.3%) signal a market that is deeply embedded in global supply chains — and therefore exposed to disruptions. The increased concentration of exports on fewer markets, combined with the volatility inherent in newer trade relationships, warrants continued monitoring. At the same time, the strong performance of Central and Eastern European producers and the EU's ability to command premium prices suggest that European optical fibre cable manufacturing retains significant competitive strengths, even as the competitive landscape grows more complex.
