Market evolution: Ceramic pipe fittings (CN 6906) — 2015–2025

Introduction

This report examines the evolution of EU trade in ceramic pipes, conduits, guttering and pipe fittings (Combined Nomenclature code 6906) over the period 2015–2025. The product category encompasses drain pipes and guttering with fittings, excluding refractory goods, laboratory pipes, and electrotechnical insulation tubing. What emerges from the data is a market undergoing a profound structural transformation: the EU has shifted from a position of net exporter to one of net importer, with exports collapsing in both volume and value terms while import dependence has grown. This transition reflects wider changes in European industrial capacity, competitive positioning, and global supply chain realignment.

1. A Decade of Collapse: The Dramatic Retreat of EU Exports

The most striking feature of the 2015–2025 period is the near-total evaporation of EU exports in ceramic pipe fittings. From a position of considerable export strength in 2015, the EU's outward trade has shrunk to a fraction of its former scale — a decline visible across value, volume, and geographic scope.

Export volumes fell by over 97 percent

In 2015, the EU exported 44,679 tonnes of ceramic pipe fittings to non-EU countries. By 2025, that figure had fallen to just 946 tonnes — a decline of 97.9 percent. The export value declined correspondingly, from €14.9 million in 2015 to €2.5 million in 2025 (−83.0%). The fact that value declined less sharply than volume indicates a substantial increase in the unit price of exported goods, rising from €334 per tonne to €2,635 per tonne (+688.6%). This suggests that what remains of EU exports consists of higher-value, specialised products rather than bulk commodity goods.

Belgium bore the brunt of the export decline

Among EU member states, Belgium experienced the most dramatic collapse in export activity. Belgian exports fell from €10.8 million in 2015 to just €210,000 in 2025 — a decline of 98.1 percent. Given that Belgium alone accounted for the majority of EU exports in 2015, its retreat is the principal driver of the aggregate decline. Germany, the second-largest exporter, saw a more moderate but still significant decline from €3.2 million to €1.2 million (−62.0%). By contrast, Italy emerged as a relative bright spot, growing from €40,000 to €454,000 (+1,026%), though from a very low base.

Export destination markets largely evaporated

The EU's traditional export markets contracted sharply. Saudi Arabia, which absorbed €10.4 million of EU exports in 2015 — making it by far the largest single destination — imported only €26,000 from the EU in 2025, a decline of 99.7 percent. Singapore, Australia, and Malaysia saw similarly severe contractions (−99.8%, −93.7%, and −94.3% respectively). Switzerland and the United Kingdom, while also declining, remained the most resilient export markets, falling by 59.0% and 65.4% respectively.

2. Rising Import Dependence and a New Geographic Order

As exports collapsed, imports moved in the opposite direction, roughly doubling in value and volume. The combined effect transformed the EU from a net exporter with a positive trade balance of €10.4 million in 2015 to a net importer with a deficit of €6.4 million by 2025.

Imports nearly doubled in value and volume

EU imports of ceramic pipe fittings grew from €4.5 million and 6,523 tonnes in 2015 to €8.9 million and 12,687 tonnes in 2025, representing increases of 97.3% and 94.5% respectively. Unlike exports, where unit prices rose dramatically, import prices remained comparatively stable — increasing only marginally from €689 per tonne to €702 per tonne (+2.0%). This stability suggests that suppliers from outside the EU offer competitively priced bulk products, maintaining price discipline even as volumes grow.

The trade balance swung from surplus to deficit

The EU's net import reliance shifted from −5.3% in 2015 (indicating a net export position) to +9.1% in 2025 (indicating net import dependence). This represents a swing of 273.7% and reflects the combined impact of rising imports and collapsing exports. At its peak, import reliance reached 16.2%, underscoring the extent to which the EU became structurally dependent on external supply.

Egypt and China emerged as dominant suppliers

The geographic composition of EU imports shifted considerably. Egypt consolidated its position as the largest supplier, growing from €2.1 million to €4.5 million (+113.0%). China experienced even more rapid growth, nearly tripling from €642,000 to €1.9 million (+197.4%). Saudi Arabia, a negligible supplier in 2015 (€2,000), surged to €569,000 by 2025 — an extraordinary increase of 28,461%. The United Kingdom, while still a significant supplier, declined from €995,000 to €659,000 (−33.7%), likely reflecting post-Brexit trade friction.

Import concentration remained moderate but shifted partners

The Herfindahl-Hirschman Index (HHI) for imports by value moved from 2,887 to 3,189 (+10.4%), indicating a modest increase in concentration. This is consistent with Egypt and China consolidating their shares while several smaller suppliers lost ground. The HHI remains below the 2,500 threshold for highly concentrated markets in its volume-based measure (7,243), but the upward trend warrants attention from a supply security perspective.

3. Structural Transformation: Production Decline and the Loss of Export Specialisation

Behind the trade figures lies a deeper structural shift in the EU's industrial capacity for ceramic pipe fittings. Production data, specialisation metrics, and volatility patterns all point to a sector that has undergone significant contraction and reorientation.

EU production volumes fell by over 85 percent

The most alarming figure in the dataset is the collapse of EU production. Output declined from 605 million kilograms in 2015 to 90 million kilograms in 2025 — a decline of 85.1%. Production value fell by 54.4%, from €175 million to €80 million. The fact that value declined less than volume implies rising unit prices for domestically produced goods, which may reflect a shift toward higher-value niche products or simply the inability to compete on price with imports.

Only Belgium and Germany retain meaningful export specialisation

Revealed Symmetric Comparative Advantage (RSCA) data for 2025 shows that only Belgium (RSCA = 0.67) and Germany (RSCA = 0.41) possess positive specialisation indices in ceramic pipe fittings. All other EU member states for which data is available show negative RSCA values, meaning they are net importers of this product relative to their overall trade profile. Several countries — Lithuania, Greece, Denmark, Ireland, and Romania — exhibit RSCA values near −1.0, indicating virtually no domestic production or export capacity.

Export propensity declined sharply while trade intensity held steady

The EU's export propensity — the share of domestic production that is exported — fell from 11.3% in 2015 to 4.0% in 2025 (−64.8%). This confirms that the decline in exports is not merely a trade phenomenon but is rooted in the erosion of production capacity. By contrast, trade intensity — which captures both imports and exports relative to production — declined only modestly, from 16.5% to 15.8% (−4.7%). This indicates that while the EU has become less outward-facing, the sector remains integrated into international trade through its import channel.

A significant price shock was detected in Saudi Arabia export flows

The volatility analysis identifies a notable supply shock event centred on 2019: exports to Saudi Arabia experienced a price shock with an abnormality score of 501.7 and a price shift of 5,718%. At that point, Saudi Arabia accounted for 50.8% of EU export value. This coincides with the period when Saudi Arabia's Vision 2023 construction programme was ramping up, likely creating a temporary spike in demand. The subsequent collapse of this export flow — Saudi Arabia went from absorbing over half of EU export value to a negligible share — is consistent with the Kingdom's strategy to develop domestic ceramic manufacturing capacity and reduce import dependence.

Export volatility was generally high for EU trade partners in this sector. Saudi Arabia (coefficient of variation = 2.12), Australia (2.09), and Belarus (1.85) showed the highest export volatility, while the most volatile import sources included Türkiye (2.28), Norway (2.06), and Japan (1.50).

Conclusion

The EU market for ceramic pipe fittings (CN 6906) underwent a fundamental transformation between 2015 and 2025. What was once a sector with a healthy export surplus — driven principally by Belgium and anchored by large contracts to Saudi Arabia — has become one characterised by production decline, export retreat, and growing import dependence. Production volumes fell by 85%, exports by 98% in volume, and the trade balance swung from a €10 million surplus to a €6 million deficit.

Several factors appear to underlie this shift. The collapse of the Saudi Arabian export market — which represented over half of EU export value at its peak — removed the sector's primary external demand driver. Simultaneously, imports from Egypt, China, and Saudi Arabia itself grew to fill the gap, suggesting that these countries have developed competitive production capacity that the EU cannot match on price for bulk commodity products. The residual EU export profile is increasingly concentrated in high-value, specialised goods, as evidenced by the near-sevenfold increase in export unit prices.

From a strategic perspective, the rise in net import reliance to 9.1% — and its peak at 16.2% — represents a meaningful shift in the EU's supply security posture for a product category used in critical infrastructure. With only Belgium and Germany retaining meaningful export specialisation, and with import concentration modestly increasing, policymakers may wish to monitor this sector for further erosion of domestic capacity.
