Market evolution: Single-layer printed circuits (CN 85340019) — 2015–2025

Introduction

This report examines the trade dynamics of single-layer printed circuits (CN 85340019) within the European Union's external trade over the 2015–2025 period. These components—consisting only of conductor elements and contacts, excluding multilayer and more complex circuits—represent a foundational segment of the electronics supply chain, used in automotive, industrial, and consumer applications.

Over the decade, the EU's trade in this product category has been shaped by significant structural shifts: declining trade volumes, evolving supplier concentration, regional production realignment, and notable price shocks linked to global disruptions. The following analysis draws on official trade data to identify and interpret the principal dynamics at play.

1. A Decade of Declining Trade Flows Despite Rising Unit Values

Overall trade contracted significantly in both directions

The EU's external trade in single-layer printed circuits experienced a broad-based decline between 2015 and 2025. Imports fell from €1.04 billion to €803 million (−23.1%), while exports dropped from €341 million to €271 million (−20.5%). The trade deficit, while still substantial, narrowed from €702 million to €532 million—an improvement of 24.3%.

Quantity declines outpaced value declines, indicating price inflation

The contraction in traded volumes was even steeper than the value figures suggest. Import quantities fell by 28.2% (from 23,004 tonnes to 16,528 tonnes), while export quantities dropped by 27.9% (from 3,254 tonnes to 2,346 tonnes). Crucially, unit prices moved in the opposite direction: import prices rose 7.1% (from €45,344/t to €48,555/t) and export prices climbed 10.2% (from €104,680/t to €115,325/t). This divergence points to a market where fewer physical units are being traded, but at higher price points—consistent with input cost inflation, supply chain tightening, and a shift toward higher-specification products within the same tariff code.

EU production mirrored the decline in external trade

Domestic production data confirms that the contraction was not simply a shift from imports to local manufacturing. EU production volumes fell by 34.3%, from 2.8 billion units to 1.84 billion units. Production value, however, was comparatively resilient—declining only 3.7% (from €1.04 billion to €1.00 billion). This mirrors the trade-side pattern: fewer units produced, but at higher average values per unit. The single-layer printed circuit market appears to be shrinking in physical terms across both trade and production, suggesting structural demand shifts rather than mere trade diversion.

2. Deepening Dependence on China Amid Concentrating Supplier Landscape

China consolidated its position as the EU's overwhelmingly dominant supplier

Throughout the 2015–2025 period, China remained the EU's primary source of single-layer printed circuits. In 2025, Chinese imports stood at €550 million—representing 68.5% of total EU imports of this product. While the absolute value declined modestly (−3.6% from the 2015 level of €570 million), China's relative share grew substantially as other suppliers contracted far more sharply.

Import concentration rose sharply, signalling increased supply risk

The Herfindahl-Hirschman Index (HHI) for imports by value increased by 49.8%, rising from 3,192 to 4,781 over the period. This significant jump indicates a material consolidation of the EU's import base. The collapse of several secondary suppliers—Hong Kong (−87.5%), Thailand (−70.3%), the United Kingdom (−61.3%), and Tunisia (−44.2%)—contributed directly to this concentration. Many of these declines likely reflect the re-routing of trade flows (e.g., Hong Kong's role as an intermediary for Chinese goods declining), Brexit-related disruptions for the UK, and competitive displacement of smaller Asian suppliers.

Export markets fragmented more gently, with the EU sending circuits mainly to China and the United States

On the export side, the EU's top destinations for single-layer printed circuits were China (€71 million, −9.2%), the United States (€36 million, +11.1%), and Morocco (€28 million, +1.8%). The United Kingdom saw a dramatic decline as an export destination (−63.8%), mirroring its decline as an import source. Japan exports collapsed by 81.3%. Export HHI rose more modestly than import HHI (from 984 to 1,148, +16.7%), reflecting a relatively more diversified but still evolving export profile.

3. Eastern European Specialisation, Western European Retreat, and Notable Price Shocks

Central and Eastern European economies emerged as the EU's specialised producers

A Revealed Symmetric Comparative Advantage (RSCA) analysis for 2025 reveals that EU specialisation in single-layer printed circuits is concentrated in Central and Eastern European member states. Bulgaria (RSCA: 0.619), Slovenia (0.606), Romania (0.552), Slovakia (0.542), and Hungary (0.510) all show strong comparative advantages. These countries accounted for a growing share of EU production in this segment, likely benefiting from lower labour costs, proximity to Western European end-markets, and established electronics manufacturing clusters (e.g., automotive wiring harness and PCB assembly in Hungary and Slovakia).

Large Western European economies saw significant trade contractions

Among EU member states, the largest importers also experienced the steepest declines. Germany remained the EU's top importer (€163 million in 2025, down 29.8%), followed by Spain (€89 million, −3.1%), Italy (€63 million, −18.8%), and Poland (€59 million, −3.9%). More dramatic contractions occurred in France (−45.2%), Ireland (−59.1%), and Austria (−66.0%). On the export side, Germany maintained its lead (€110 million, −4.0%), while Hungary's exports collapsed by 84.4% and the Netherlands' fell by 78.5%.

Supply chain disruptions triggered measurable price shocks, particularly from China in 2022

The volatility analysis identifies several significant price shocks during the period. The most impactful was a Chinese import price shock centred on 2022, with an abnormality score of 79.6 and a price shift of +20.8%. Given that China accounts for over 90% of the value share in this shock's scope, the effect on EU procurement costs was substantial. This event aligns with the post-COVID supply chain disruptions and raw material cost surges that characterised the 2021–2022 period globally.

Additional shocks were detected on the export side: a Japanese export price spike in 2020 (+254%, though from a small base of 1.7% value share) and a UK export price shock in 2021 (+216.9%, at 8.7% value share), the latter likely related to post-Brexit trade adjustment.

Import volatility varied widely across partners

The coefficient of variation for import values ranged from low (China: 0.11, reflecting stable flows) to extremely high (United Kingdom: 1.00, indicating erratic trade patterns post-Brexit). This pattern underscores that while China offers volume stability, the concentration risk remains: any future disruption to Chinese supply would have outsized consequences for the EU's single-layer printed circuit availability.

Conclusion

The EU's market for single-layer printed circuits (CN 85340019) underwent a pronounced structural contraction over 2015–2025. Trade volumes and production quantities fell significantly—by roughly 28–34%—while values proved more resilient, indicating upward price pressure and possible compositional shifts toward higher-value products within this tariff line.

The most consequential strategic development has been the deepening concentration of import supply on China. As secondary suppliers (Hong Kong, Thailand, the UK, Taiwan) saw their trade flows collapse, China's share of EU imports rose to nearly 70%, and the import HHI increased by 50%. This concentration, combined with the documented 2022 price shock from Chinese suppliers, highlights a meaningful vulnerability in the EU's electronics supply chain for this component category.

On a more positive note, the EU's net import reliance declined from 39.3% to 31.5%, and export propensity edged upward from 29.9% to 31.7%, suggesting some improvement in the bloc's competitive positioning. Meanwhile, Central and Eastern European member states—Bulgaria, Slovenia, Romania, Slovakia, and Hungary—have emerged as the EU's specialised producers in this segment, anchoring a regional production base that could serve as a foundation for supply chain resilience strategies.
