Market evolution: Cork and cork articles (CN 45) — 2015–2025

Introduction

The European Union is the world's dominant producer and exporter of cork, a natural material whose trade is shaped by the geography of cork oak forests concentrated in the western Mediterranean — above all Portugal, but also Spain, France, Italy and North Africa. This report examines EU trade in Combined Nomenclature heading 45 (CORK AND ARTICLES OF CORK) over the period 2015–2025, covering raw natural cork, agglomerated cork products and finished articles. The overall trade data reveal a sector that has maintained a large and growing trade surplus — rising from €460 million to €517 million — while undergoing significant structural shifts in volumes, prices, partner geography and the composition of product flows.

1. Rising prices mask a structural decline in traded volumes

The most striking macro-level trend over 2015–2025 is a divergence between value and quantity trajectories on both the export and import sides. EU export revenues grew by 10.0% (from €522 million to €574 million), yet export volumes fell by 30.1% (from 76,658 tonnes to 53,572 tonnes). The gap was filled by a 57.5% increase in the average export unit price, which climbed from €6,810/tonne to €10,723/tonne. A similar, though less pronounced, dynamic occurred on the import side: import values declined by 6.2% while quantities dropped by 28.8%, again with rising unit prices (+31.7%) partially offsetting the volume contraction.

Segment-level data confirms that the volume contraction is concentrated in processed cork products

Breaking down exports by sub-heading reveals that the quantity decline is not uniform across product types. The largest category by far — agglomerated cork and articles thereof (CN 4504) — saw volumes fall from 56,020 tonnes to 37,005 tonnes (−34.0%) while its value barely dipped, remaining around €345 million, thanks to unit prices that more than doubled (from €4,273/tonne to €9,336/tonne). Articles of natural cork (CN 4503) followed a similar pattern: volumes fell 42.0% (from 10,408 t to 6,040 t) and value declined by 25.2%, yet unit prices rose 28.9% (from €25,223/tonne to €32,517/tonne), cushioning the revenue loss. By contrast, raw natural cork exports (CN 4501) remained volume-stable at around 9,800 tonnes while value grew 52.0%, implying strong price appreciation from €1,817/tonne to €2,708/tonne. Natural cork in blocks and sheets (CN 4502) saw the most dramatic value surge — from €2.0 million to €6.0 million — though volumes fluctuated and remained small.

EU production grew while export volumes fell, suggesting a redirection toward domestic processing and consumption

Notably, EU production of cork articles increased over the period — production volume rose 14.3% (from 499 million kg to 571 million kg) and production value grew 15.5% (from €2.21 billion to €2.55 billion). This indicates that the decline in traded quantities does not reflect a shrinking industry; rather, a growing share of output may be absorbed domestically or re-routed through intra-EU channels not captured in extra-EU trade statistics. Meanwhile, the EU's net import reliance deepened from −21.9% to −26.0%, confirming the bloc's strengthening position as a net exporter of cork products to the rest of the world.

2. A reshaping of trade partners driven by geopolitics and North African sourcing shifts

The geographical structure of EU cork trade has evolved significantly between 2015 and 2025, with two major dynamics at play: a collapse in exports to Russia following the 2022 invasion of Ukraine and subsequent sanctions, and a notable reorientation of EU imports toward North African suppliers at the expense of Switzerland and the United States.

The Russian market has been almost entirely lost

EU exports to the Russian Federation fell from €33.6 million (2015) to just €148,178 (2025), a decline of 99.6%. The supply shock analysis identifies this as the most severe shock event in the dataset, with a shift of −99.1% centred on 2025 and an abnormality score of 3.1. Russia's share of total EU cork exports fell from approximately 6.4% to near zero. This loss was partially absorbed by growth elsewhere, particularly in the United Kingdom.

The United Kingdom's import bill for EU cork grew from €35.6 million to €54.4 million (+52.9%), making it the second-largest non-EU destination after the United States. This may partly reflect post-Brexit trade recording effects — flows that were previously intra-EU now appear as extra-EU exports — as well as sustained demand from the UK wine and spirits sector for cork stoppers. Meanwhile, the United States remained by far the dominant market at €204 million, with only a modest 2.9% decline, underscoring the resilience of transatlantic cork demand, particularly for wine closures.

North African suppliers have gained ground as EU import sources

On the import side, the composition of sourcing shifted markedly. Morocco remained the largest supplier but saw its share decline from €18.1 million to €10.4 million (−42.2%). By contrast, Algeria (+133.2%, from €2.3 million to €5.5 million), Tunisia (+47.6%, from €4.9 million to €7.2 million), and China (+74.6%, from €9.6 million to €16.8 million) all increased their presence. Switzerland and the United States, previously significant import suppliers, halved their contributions. The growing role of Algeria and Tunisia is consistent with the geographic distribution of cork oak forests across the Maghreb and with rising local processing capacity in those countries.

Partner concentration has declined on both sides of the trade

The Herfindahl–Hirschman Index (HHI) for export value fell from 1,868 to 1,569 (−16.0%), and import value HHI declined from 1,803 to 1,642 (−8.9%). In volume terms, the same pattern holds. These HHI values remain in the moderately concentrated range, but the downward trend indicates a broadening of the EU's trade partner base — a positive signal for supply-chain resilience.

3. Portugal anchors EU cork dominance while intra-EU specialisation intensifies

The EU's position as a net exporter of cork is overwhelmingly driven by Portugal, which accounted for approximately 75% of the bloc's extra-EU cork exports in 2025. Meanwhile, several smaller EU Member States have significantly expanded their cork export profiles, and the degree of specialisation within the EU has become more pronounced.

Portugal's export dominance has been reinforced over the decade

Portugal's extra-EU cork exports rose from €413 million to €430 million (+4.1%), maintaining its position as the undisputed leader. Spain also expanded strongly (+45.6%, from €44.5 million to €64.8 million), and France doubled its exports from €18.3 million to €36.6 million (+100.4%). Italy and Germany, by contrast, saw modest declines. The combined output of Portugal and Spain represents over 87% of EU cork exports by value.

Specialisation data reveals an extreme concentration of comparative advantage in Iberia

Using the Revealed Symmetric Comparative Advantage (RSCA) index, Portugal scored 0.955 in 2025 — near the theoretical maximum of 1.0 — with an RCA of 43.2, indicating that cork represents a vastly disproportionate share of its exports relative to the EU average. Spain followed with an RSCA of 0.640 (RCA 4.56). No other Member State approaches these levels; France, Italy and Denmark all have RSCA values below zero, indicating no particular specialisation. Among the least specialised, Cyprus, Ireland, Malta and Estonia show near-zero involvement in cork exports.

Bulgaria's emergence as a cork exporter is the fastest-growing trend among smaller Member States

Bulgaria's cork exports surged from just €258,000 in 2015 to €3.0 million in 2025 — an increase of over 1,070%. While the absolute numbers remain small, this growth is notable and may reflect investment in agglomerated cork processing or re-export activity. Poland similarly expanded from €2.3 million to €2.7 million. On the import side, Poland saw the most dramatic growth among EU importers (+199.9%, from €0.4 million to €1.2 million), and France's imports rose 56.7% to €6.0 million, suggesting growing domestic demand for cork inputs in those countries.

The sector exhibits moderate volatility, with key risks concentrated in a handful of markets

The coefficient of variation analysis shows that most major export partners exhibit relatively low volatility (CV below 0.35), reflecting the steady, mature nature of cork demand — primarily driven by the wine industry. Chile (CV 0.11) and the United States (CV 0.15) are the most stable export markets. The exceptions are Russia (CV 0.73), which reflects the shock of sanctions, and Turkey (CV 0.55). On the import side, Russia (CV 1.87) and Switzerland (CV 1.43) are the most volatile suppliers, though neither is a major source.

Two additional shock events were detected beyond the Russia collapse: a price shock in exports to Australia in 2021 (−19.5%, abnormality 5.2) and a price shock to Chile in 2020 (−6.1%, abnormality 4.2). Both may reflect pandemic-related disruptions to global shipping and wine logistics.

Conclusion

Over 2015–2025, the EU cork sector has become more valuable but less voluminous in trade terms, with a 57.5% rise in export unit prices more than compensating for a 30% decline in shipped quantities. This price appreciation likely reflects both inflationary pressures and a shift toward higher-value-added cork products. The EU's trade surplus widened to €517 million, underpinned by the overwhelming dominance of Portugal, which alone accounts for roughly 75% of extra-EU cork exports. The geopolitical shock of EU sanctions on Russia eliminated a €34-million export market almost entirely, while the United Kingdom — partly due to post-Brexit trade classification effects — has emerged as the second-largest destination. On the supply side, North African countries (Algeria, Tunisia) are playing a growing role as import sources, broadening the EU's supplier base. With production continuing to grow and the cork industry benefiting from sustainability trends — cork being a renewable, carbon-sequestering material — the sector appears structurally resilient, though concentrated in a very small number of Iberian producers and exposed to demand fluctuations in the global wine industry.
