Market evolution: Heavy steel plate (CN 720851) — 2015–2025

Introduction

This report examines the trade evolution of product CN 720851 — Flat-rolled products of iron or non-alloy steel, of a width ≥ 600 mm, not in coils, simply hot-rolled, not clad, plated or coated, of a thickness of > 10 mm, without patterns in relief — in EU extra-EU trade over the period 2015–2025. This category covers heavy hot-rolled steel plates used in construction, shipbuilding, heavy machinery, and energy infrastructure. The data reveals a structural transformation: the EU has shifted from a net exporter to a net importer, its export volumes have nearly halved, and the geographic composition of its import supply base has been fundamentally reconfigured by geopolitical shocks, trade defence measures, and the rise of Asian suppliers.

I. From net exporter to net importer: a structural trade reversal

The EU's trade balance swung from surplus to deep deficit

The most striking development over the decade is the reversal of the EU's trade position. In 2015, the EU recorded a modest trade surplus of approximately €155.3 million. By 2025, this had turned into a deficit of roughly €493.7 million — a swing of over €650 million. This was driven by a simultaneous decline in export value (from €1.045 billion to €676.6 million, or −35.3%) and a rise in import value (from €890.1 million to €1.170 billion, or +31.5%).

Export volumes collapsed far more steeply than export values

The near-halving of export quantities (−58.7%) contrasts with a more moderate decline in value (−35.3%), because unit export prices rose significantly over the period — from €602/t in 2015 to €915/t in 2025 (+51.9%). Similarly, import prices rose from €481/t to €654/t (+36.1%). These price increases largely reflect the global commodity price cycle, particularly the steel price surge of 2021–2022. Indeed, the data shows peak import prices of €1,131/t and peak export prices of €1,090/t around 2022, before a subsequent correction. The EU is now selling less steel at higher prices, while buying roughly the same volume as a decade ago — but at substantially higher unit costs.

Domestic production grew in volume but shrank in value

EU domestic production of this product rose from 11.08 billion kg in 2015 to 12.28 billion kg in 2025 (+10.8%), yet production value declined from €8.80 billion to €6.24 billion (−29.1%). This divergence — more tonnes, less revenue — underscores the deflationary pressure that returned after the 2021–2022 price spike, as well as a structural shift in the EU's position: production is sustained by domestic demand increasingly met through a mix of local output and rising imports, while the export channel has narrowed considerably.

Net import reliance shifted from negative to positive

The net import reliance indicator moved from −1.5% in 2015 to +9.3% in 2025. A negative value in 2015 indicated the EU was a net exporter; the positive value in 2025 confirms the structural import dependence. The swing is even more dramatic when looking at the trough: at its lowest point (around 2018–2019), net import reliance was approximately −24.1%, meaning the EU was heavily exporting. The subsequent reversal reflects both the export contraction and the resilience of import volumes.

Export propensity declined sharply

The export propensity — the share of EU production that is exported — fell from 30.5% in 2015 to just 17.2% in 2025 (−43.5%). This is the most salient autonomy metric in the dataset, with a salience score of 76.3. It means that the EU's heavy plate industry is increasingly oriented toward the domestic market rather than international customers, a significant strategic shift in a product critical for infrastructure and defence applications.

II. A radical restructuring of the supplier landscape

Asian suppliers replaced traditional European and Chinese sources

The import side reveals a dramatic reconfiguration of the EU's supply base. The most consequential changes among the top import partners are:

China's collapse reflects the success of EU trade defence measures

In 2015, China was the EU's largest single supplier of heavy steel plate by value (€286.1 million). By 2025, imports had fallen to just €15.7 million — a decline of 94.5%. The data also shows extreme volatility in Chinese supply, with a coefficient of variation of 1.99 — the highest among all import partners. A major supply shock is detected in 2021, when Chinese volumes collapsed by −99.2%, followed by a price shock in 2022 (+228.1%). This pattern is consistent with the imposition and escalation of EU anti-dumping and anti-subsidy duties on Chinese steel products, which effectively priced Chinese heavy plate out of the EU market.

Ukraine's supply was severed by the 2022 invasion

Ukraine was the EU's second-largest supplier in 2015 (€234.6 million) and remained significant through 2021 (reaching a peak of €501.1 million). By 2025, imports from Ukraine had essentially ceased (€31,182). The coefficient of variation for Ukrainian imports is 0.75, reflecting the abrupt disruption caused by Russia's full-scale invasion in February 2022. Ukrainian steel production and logistics were severely disrupted, and the data captures this as a near-total supply collapse.

India, Indonesia, and South Korea filled the gap

The void left by China and Ukraine was substantially filled by three Asian suppliers:

• India surged from €10.4 million in 2015 to €205.0 million in 2025 (+1,875%), with a peak of €348.6 million.
• Indonesia grew from €25.2 million to €222.2 million (+783%), peaking at €322.5 million.
• South Korea rose from €74.6 million to €309.3 million (+315%), with a peak of €519.6 million.

Together, these three countries now supply approximately €736 million in heavy plate to the EU — replacing the combined €605 million that China and Ukraine provided in 2015. This substitution reflects both the commercial agility of Asian steelmakers and the EU's diversification strategy in response to supply chain vulnerabilities exposed by trade tensions and the war in Ukraine.

Russia's supply declined but did not collapse

Imports from Russia fell from €85.2 million to €50.2 million (−41.1%). This decline is notable but far less dramatic than the Ukrainian or Chinese collapses, suggesting that Russian steel continued to flow into the EU during much of the period, likely through intermediaries or under sanctions carve-outs for certain products. The moderate volatility (CV of 0.35) supports the interpretation of a gradual rather than abrupt reduction.

EU exports to the United States virtually disappeared

On the export side, the most dramatic shift was the collapse of exports to the United States — from €300.0 million in 2015 to just €6.7 million in 2025 (−97.8%). The US was the EU's largest export market in 2015; by 2025 it had become negligible. This coincides with the Section 232 tariffs imposed by the US in 2018 on steel imports, which imposed a 25% duty on EU steel. Despite subsequent negotiations and partial tariff-rate quotas, the data shows that EU heavy plate was effectively shut out of the US market.

The United Kingdom emerged as the EU's largest export destination, growing from €70.2 million to €184.4 million (+162.6%), reflecting deepening bilateral trade integration after Brexit, facilitated by the Trade and Cooperation Agreement.

III. Shifting intra-EU specialisation and concentration patterns

Concentration of imports diversified while exports remained fragmented

The Herfindahl-Hirschman Index (HHI) for import value fell from 2,180 in 2015 to 1,747 in 2025 (−19.9%), moving from a moderately concentrated to a less concentrated market structure. This reflects the transition from reliance on a few large suppliers (China, Ukraine) to a broader base of Asian and other exporters. Export concentration also declined, from 1,296 to 1,124 (−13.2%), remaining relatively fragmented throughout.

The fall in import HHI is a double-edged development: while it reduces dependence on any single supplier, the new diversified base is geographically more distant and potentially more exposed to shipping disruptions and geopolitical tensions in the Indo-Pacific region.

Intra-EU specialisation is concentrated in northern and southern member states

The specialisation analysis for 2025 reveals that the most specialised EU producers of heavy plate are:

The least specialised — meaning those most dependent on imports for this product — include Greece (RSCA −0.889), Hungary (−0.861), Romania (−0.810), and Portugal (−0.725).

Italy and Belgium together account for over 35% of EU production, making them the industrial backbone of the EU's heavy plate capacity. The high specialisation of Denmark and Finland likely reflects niche, high-value production linked to their maritime and energy sectors.

EU imports are increasingly channelled through Belgium, Spain, and Denmark

Among EU member states, the largest importing countries shifted notably:

Belgium's tripling of imports (to €394.8 million) likely reflects its role as a major port-of-entry hub (Antwerp/Zeebrugge), through which steel is imported and redistributed across the EU. Germany's sharp decline (−71.9%) is notable given its industrial weight and may reflect a shift toward domestic sourcing or reduced demand from its manufacturing sector.

The thicker plate segment dominates but has contracted in trade volume

A breakdown by sub-product shows that the thickest plates (CN 72085120, thickness > 15 mm) account for the bulk of both imports and exports. However, import volumes of this sub-product declined from 1.453 million tonnes in 2015 to 1.140 million tonnes in 2025, while the narrower-width segment (CN 72085198, 600 mm–2,050 mm, 10–15 mm thickness) surged from 203,531 tonnes to 465,753 tonnes — more than doubling. This suggests growing demand for medium-thickness, narrower plates, potentially driven by specific industrial applications such as wind tower manufacturing, shipbuilding, or construction.

Conclusion

Over the 2015–2025 period, the EU's heavy steel plate market underwent a fundamental transformation. The EU shifted from a net exporter with a €155 million surplus to a net importer with a €494 million deficit. Export volumes nearly halved, driven by the loss of the US market following Section 232 tariffs and a general decline in competitiveness on third-country markets. On the import side, the supply landscape was radically reshaped: China and Ukraine — once the two largest suppliers, accounting for over €500 million combined — have been almost entirely displaced. Their roles have been assumed by India, Indonesia, and South Korea, whose combined exports to the EU now exceed €730 million.

These shifts reflect the interplay of trade defence policy, geopolitical conflict, and market adaptation. The EU's anti-dumping measures successfully curtailed Chinese imports but did not prevent a broader increase in import reliance. The war in Ukraine eliminated a major traditional supplier. And US protectionism closed the EU's largest export market. The result is a sector that produces more steel by volume but earns less by value, exports less, and depends more on distant Asian suppliers — a configuration that raises both economic and strategic questions for European industrial policy.
