Market evolution: Electrolytic zinc coated steel (CN 721030) — 2015–2025

Introduction

This report examines the trade dynamics of the European Union for product CN 721030, which covers flat-rolled steel products electrolytically plated or coated with zinc. The analysis, based on data from 2015 to 2025, reveals a fundamental transformation in the EU's position. Over this decade, the EU transitioned from a net exporter with a positive trade balance to a net importer, driven by a sharp contraction in export volumes and a structural reshaping of its trade partnerships. These shifts occurred alongside rising market concentration and significant price volatility, reflecting broader changes in global supply chains and EU industrial capacity.

The Erosion of the EU's Export Competitiveness

The period from 2015 to 2025 was characterized by a dramatic decline in the EU's export performance for electrolytic zinc coated steel. This contraction occurred in both volume and value, fundamentally altering the bloc's trade balance.

Collapse in Export Volumes and Values

The EU's export quantity of CN 721030 products fell by 64.1%, from 222,336 tonnes in 2015 to just 79,710 tonnes in 2025. Despite rising unit export prices, which increased by 48.9% to EUR 959 per tonne, the overall export value still declined by 46.6% to EUR 76.5 million (trade overview). This indicates a severe loss in export volume that price increases could not offset.

Shifting Trade Balance and Import Partnerships

Consequently, the EU's trade balance deteriorated from a surplus of EUR 38.9 million in 2015 to a deficit of EUR 4.9 million in 2025. While imports also decreased in value by 21.9%, their decline was less severe than that of exports (trade overview). A look at the top import partners reveals a market becoming more reliant on a few key suppliers, most notably South Korea, which remained the dominant importer throughout the period despite a 14.5% decline in value (top partners).

Increased Market Concentration and Supplier Volatility

As overall trade volumes contracted, the market became more concentrated and volatile, highlighting growing dependencies on specific trade flows that are prone to disruption.

Rising Concentration in Imports

The Herfindahl-Hirschman Index (HHI) for import concentration by value increased by 19.0% over the period, rising from 6,692 to 7,965. This level indicates a highly concentrated import market (concentration). South Korea was the primary driver of this concentration, maintaining its position as the largest source of imports by value (top partners).

High Volatility in Secondary Trade Flows

While core trade with partners like the UK and South Korea was relatively stable (low coefficient of variation), trade with many other partners was highly volatile. For instance, imports from Brazil and Türkiye exhibited extreme volatility (CV of 1.08 and 1.13, respectively), as did exports to the United States and Argentina (volatility). Specific shock events, such as a 56.4% price surge for EU exports to China in 2022, further underscore the instability in peripheral trade relationships (supply shocks).

Structural Decline in EU Production and Strategic Vulnerability

Behind the trade figures lies a stark contraction in EU domestic production capacity, which has reconfigured the bloc's strategic position and autonomy in this product segment.

Plummeting Domestic Production

EU production of CN 721030 products collapsed over the decade. Production quantity (in kg) fell by 67.4%, from 3.68 billion kg in 2015 to 1.20 billion kg in 2025. The value of production also declined by 27.5% (production volumes). This drop in domestic output is the fundamental cause of the reduced export capacity and the shift toward net import reliance.

Increased Autonomy Risks

The EU's net import reliance, while still slightly negative (indicating a net exporter status), deteriorated by 33.7% by 2025. More tellingly, trade intensity—the share of production involved in foreign trade—fell by 30.3% to its lowest point in the period at 12.2% (trade intensity). This suggests a market that is becoming less integrated into global flows but simultaneously more vulnerable due to weakened domestic capacity. The geographic specialization analysis shows that Belgium, Austria, and Slovakia are the primary EU producers with comparative advantage, while major economies like France and Romania are net importers (specialisation).

Conclusion

The EU market for electrolytic zinc coated steel (CN 721030) underwent a profound restructuring between 2015 and 2025. The core narrative is one of deindustrialization in this segment: a severe contraction in domestic production led to the erosion of export capacity, flipping the EU from a net exporter to a net importer and weakening its trade balance. This shift was accompanied by increased concentration in import sources and significant volatility in secondary trade flows. The resulting landscape is one of heightened dependency on a smaller number of foreign suppliers, notably South Korea, and reduced resilience due to diminished domestic production. These trends underscore the challenges facing the EU's steel sector in maintaining global competitiveness and strategic autonomy in key industrial materials.
