Market evolution: Non-malleable cast iron articles (CN 732510) — 2015–2025

Introduction

This report examines the evolution of EU external trade in articles of non-malleable cast iron not elsewhere specified (Combined Nomenclature code 732510) over the period 2015–2025. The product category covers a wide range of cast-iron components — from manhole covers and pipe fittings to decorative and industrial castings — and maps to PRODCOM code 25.99.29.13. Scope & Definitions

Over the full eleven-year window, the EU has remained a net importer of this product, with a structural trade deficit that widened from €169 million in 2015 to €178 million in 2025. Behind this headline figure, however, lie significant shifts in volumes, unit values, partner geography, and supply concentration — dynamics that were amplified by the commodity-price shock of 2021–2022 and the geopolitical reconfiguration of trade following the war in Ukraine. The sections below organise these findings into three thematic areas.

1. Shrinking volumes masked by rising unit values

1.1 Import quantities fell while import values held broadly steady

Between 2015 and 2025, EU imports of CN 732510 declined from 249,247 tonnes to 207,883 tonnes — a drop of 16.6%. Yet over the same period, the total import value barely moved, falling just 0.8% from €354.7 million to €352.0 million. This paradox is explained by a sustained rise in average import unit values, which climbed from €1,423/t to €1,693/t (+19.0%). General Overview

1.2 EU exports contracted even more sharply in volume terms

EU exports to non-EU partners fell from 75,208 tonnes in 2015 to only 52,385 tonnes in 2025 (−30.3%). The decline in export value was more moderate at −6.4% (from €185.6 million to €173.8 million), again because export unit values rose steeply — by 34.4%, from €2,468/t to €3,316/t. EU export prices are structurally higher than import prices (€3,316/t vs. €1,693/t in 2025), consistent with the EU producing higher-value, more specialised cast-iron articles while importing higher volumes of more commoditised products.

1.3 EU production shifted from volume to value

PRODCOM production data confirm the same pattern at the domestic level. EU production volume fell from 400 million kg in 2015 to 358 million kg in 2025 (−10.4%), while production value rose from €600 million to €730 million (+21.6%). Production volumes This suggests the European cast-iron industry has been moving up the value chain, focusing on higher-margin products while ceding commodity-grade output to lower-cost foreign producers.

2. A geographic reorientation of trade flows

2.1 China remains the dominant supplier but is losing ground

China has consistently been the EU's largest single source of imports, accounting for €152.1 million in 2015 and €128.0 million in 2025 (−15.9%). However, its share of total imports has eroded as other suppliers have grown. India, the second-largest supplier, saw its imports fall 9.4% (from €51.8 million to €46.9 million), while Türkiye's shipments rose 16.1% (from €40.1 million to €46.6 million), nearly closing the gap with India.

2.2 The United Kingdom and Norway emerged as growing import sources

Two of the most striking import-side trends are the rise of the United Kingdom (+46.6%, from €26.4 million to €38.7 million) and Norway (+77.7%, from €24.8 million to €44.1 million) as suppliers to the EU. The UK increase likely reflects post-Brexit trade reclassification and the deepening of bilateral supply chains in cast-iron products. Norway's surge may be linked to its energy-sector demand cycles and cross-border foundry networks in Scandinavia.

2.3 EU export geography shifted away from Russia and Norway, toward Serbia and Türkiye

On the export side, the most dramatic changes include a near-total collapse of EU exports to Russia (from €5.8 million to €0.3 million, −95.6%) — clearly a consequence of sanctions imposed after 2022 — and a steep decline in exports to Norway (−60.8%). In contrast, exports to Serbia grew by over 1,100% (from €0.7 million to €7.9 million) and exports to Türkiye more than doubled (+102.0%). Switzerland remained the largest single export destination, with a modest +4.6% increase to €45.0 million. Partners

2.4 At the EU-member level, the Netherlands and France saw notable shifts

Among EU Member States, the Netherlands experienced the most striking change on the import side, with import values surging from €12.4 million to €48.7 million (+292.7%), suggesting a growing role as a gateway or redistribution hub. Meanwhile, Germany's imports declined 38.1% (from €87.2 million to €54.0 million). On the export side, France saw a dramatic contraction (from €47.5 million to €25.2 million, −46.8%), while Belgium's exports grew 68.6% to €22.8 million. Reporters

3. Rising import dependence and supply-chain concentration risks

3.1 Net import reliance nearly doubled

The EU's net import reliance for CN 732510 rose from 10.4% in 2015 to 19.2% in 2025 — an increase of 83.8%. It peaked at 28.3% at some point during the period. This widening gap between domestic production and consumption is a structural vulnerability: it means the EU is increasingly dependent on external sources for a category of industrial goods that underpins infrastructure, water management, and heavy machinery.

3.2 Import-source concentration declined, but China's dominance persists

The Herfindahl-Hirschman Index (HHI) for import concentration by value fell from 2,329 to 1,994 (−14.4%), indicating a modest diversification of supply sources. China alone, however, still accounts for more than one-third of all imports by value. Export-side concentration remained broadly stable (HHI around 1,232–1,277), reflecting the EU's already diversified customer base.

3.3 Price shocks in 2022 underscored supply-chain fragility

The volatility analysis reveals that the most pronounced supply shock occurred in 2022, when the import unit value from India spiked by 48.3% (abnormality score 4.5), affecting a trade flow that represents 15.4% of EU import value. A simultaneous 15.6% price shock from the United Kingdom (abnormality 3.0, 11.2% value share) compounded the effect. These shocks coincided with the global commodity-price surge triggered by energy-market disruptions and the war in Ukraine, which elevated input costs (coke, scrap, energy) for foundries worldwide.

3.4 Specialisation data point to a two-speed European industry

The revealed comparative advantage analysis for 2025 shows a sharp divide within the EU. Denmark (RSCA 0.77) and Czechia (RSCA 0.53) are strongly specialised in this product, with product-specific shares of 13.2% and 15.8% of their total exports respectively. France (RSCA 0.42) and Poland (RSCA 0.31) also show notable specialisation. At the other end, Ireland, Estonia, Greece, Romania, and Hungary have near-zero or negligible export presence in this category. This asymmetry suggests that the EU's export capacity in non-malleable cast iron articles is concentrated in a handful of member states, which could amplify vulnerability if those specific national industries face disruption.

Conclusion

Over the 2015–2025 period, the EU market for non-malleable cast iron articles (CN 732510) has undergone a quiet but significant transformation. Volumes traded — both in imports and exports — have declined substantially, yet trade values have been sustained by steadily rising unit prices, reflecting both global cost inflation and a shift toward higher-value production. Geographically, the trade map has been redrawn: Russia has been effectively disconnected as an export market, Türkiye and Serbia have gained importance, and within the EU the Netherlands has emerged as a major import hub while Germany and France have seen their positions erode.

Most critically, the EU's net import reliance has nearly doubled, reaching 19.2% by 2025, even as the import supplier base has modestly diversified. The 2022 price shocks from India and the United Kingdom demonstrated how exposed the EU remains to external supply disruptions. With European production volumes in decline and specialisation concentrated in a small number of member states, policymakers and industry stakeholders should monitor this segment closely — particularly as trade policy (anti-dumping measures, carbon border adjustments) and geopolitical tensions continue to reshape the competitive landscape for basic industrial castings.
