Market evolution: Plastic pipes and fittings (CN 3917) — 2015–2025
Introduction
This report examines the EU's external trade in plastic tubes, pipes, hoses, and fittings (Combined Nomenclature code 3917) over the period 2015–2025. The product heading covers a broad family of items — from rigid polyethylene and PVC pipes to flexible hoses, reinforced tubing, and plastic fittings such as joints, elbows, and flanges — widely used in construction, water infrastructure, agriculture, and industrial applications.
Over the decade, the EU has remained a net exporter of these products. However, beneath this headline stability, the underlying dynamics reveal significant structural shifts. Export values have grown substantially while volumes have been essentially flat; import growth has been both strong in value and transformative in volume; and the geographic and product composition of trade has been reshaped by geopolitical events, supply-chain realignments, and price inflation. The analysis that follows draws on the trade data provided and is structured around three main findings.
1. The Price-Driven Expansion: Strong Value Growth Masking Stagnant Volumes
EU export revenues nearly doubled, but tonnage barely moved
Between 2015 and 2025, EU exports of CN 3917 products rose from €3.52 billion to €5.24 billion — a gain of 49.1% in value. Over the same period, export quantities fell marginally, from 557,878 tonnes to 550,263 tonnes (−1.4%). The entire value expansion was therefore driven by a 50.9% increase in unit export prices, which climbed from €6,301/t to €9,511/t.
| Metric | 2015 | 2025 | Change |
|---|---|---|---|
| Export value (€ bn) | 3.52 | 5.24 | +49.1% |
| Export quantity (kt) | 557.9 | 550.3 | −1.4% |
| Export price (€/t) | 6,301 | 9,511 | +50.9% |
This pattern is consistent across most product segments. For example, the unit export price of fittings (391740) rose from €9,933/t to €14,865/t (+49.6%) while exported volumes fell from 91,038 t to 87,460 t (−3.9%). Similarly, flexible reinforced hoses (391739) saw their export price jump from €6,199/t to €10,297/t (+66.1%), even as volumes grew only modestly from 73,005 t to 78,308 t (+7.3%).
The United States emerged as the EU's fastest-growing export market
A notable feature of export growth has been the surge in demand from the United States. EU exports to the US grew from €354 million in 2015 to €700 million in 2025 — a near-doubling (+98.0%). By 2025, the US had become the EU's largest single-country export destination by value, overtaking the United Kingdom and Switzerland. A price shock was detected in US-bound exports around 2019, with an abnormality score of 39.6 and a 25.2% price shift, indicating a period of sharp repricing.
| Top EU export partners | 2015 (€ mn) | 2025 (€ mn) | Change |
|---|---|---|---|
| United States | 354 | 700 | +98.0% |
| United Kingdom | 389 | 515 | +32.4% |
| Switzerland | 364 | 515 | +41.5% |
| China | 268 | 322 | +20.1% |
| Norway | 145 | 179 | +23.4% |
| Morocco | 69 | 189 | +174.9% |
By contrast, exports to the Russian Federation collapsed from €254 million to just €27 million (−89.2%), almost certainly reflecting the impact of EU sanctions following Russia's invasion of Ukraine. This had a measurable effect on export volatility: the coefficient of variation for the Russia trade flow was 0.52 — the highest among the EU's major export partners.
EU domestic production expanded strongly, reinforcing the export base
EU production of CN 3917 products grew from 3.86 billion kg to 4.71 billion kg in volume (+22.1%) and from €8.77 billion to €17.05 billion in value (+94.4%) over the period. This near-doubling of production value, alongside stagnant export volumes, suggests that a growing share of output was absorbed by the domestic market or that the product mix shifted towards higher-value items. Either way, the EU's manufacturing base for plastic pipes and fittings remains robust and is a foundation for continued export competitiveness.
2. Import Surge and Supplier Diversification: A Structural Shift in Sourcing
Import volumes nearly doubled, led by rigid polyethylene pipes
While export volumes were flat, imports told a very different story. Total import quantities rose from 239,585 tonnes to 424,685 tonnes (+77.3%), and import values climbed from €1.72 billion to €3.34 billion (+94.6%). Import unit prices increased more modestly (+9.8%, from €7,171/t to €7,874/t), indicating that the import expansion was primarily volume-driven.
| Metric | 2015 | 2025 | Change |
|---|---|---|---|
| Import value (€ bn) | 1.72 | 3.34 | +94.6% |
| Import quantity (kt) | 239.6 | 424.7 | +77.3% |
| Import price (€/t) | 7,171 | 7,874 | +9.8% |
The most dramatic volume growth occurred in rigid polyethylene pipes (391721), where imports surged from 32,873 tonnes to 95,936 tonnes — a threefold increase (+191.8%). This sub-category went from being the third-largest import segment to the largest by tonnage, displacing fittings (391740) from the top position.
| Import sub-category | 2015 vol. (t) | 2025 vol. (t) | Change |
|---|---|---|---|
| Rigid PE pipes (391721) | 32,873 | 95,936 | +191.8% |
| Reinforced flexible hoses (391739) | 39,314 | 81,805 | +108.1% |
| Fittings (391740) | 53,119 | 65,247 | +22.8% |
| Rigid PVC pipes (391723) | 18,326 | 38,193 | +108.4% |
| Flexible hoses, no fittings (391732) | 29,029 | 34,526 | +18.9% |
| Rigid other plastics (391729) | 21,969 | 38,533 | +75.4% |
| Rigid PP pipes (391722) | 15,185 | 24,238 | +59.6% |
This volume surge suggests growing EU demand for infrastructure-grade piping — likely driven by investments in water networks, district heating, and construction — that domestic production alone could not satisfy.
Product segment breakdown — imports
Turkey, China, and Serbia emerged as fast-growing suppliers
The composition of the EU's import supplier base shifted markedly. China and Turkey — already present in 2015 — expanded their shares dramatically:
| Supplier | 2015 imports (€ mn) | 2025 imports (€ mn) | Change |
|---|---|---|---|
| China | 187 | 502 | +169.0% |
| Türkiye | 104 | 255 | +145.3% |
| Serbia | 77 | 246 | +219.2% |
| Switzerland | 342 | 481 | +40.7% |
| United Kingdom | 314 | 459 | +46.5% |
Serbia's rise is particularly striking: a 219% increase over the decade, reflecting the country's growing integration into EU manufacturing supply chains (Serbia is an EU candidate country with preferential trade access). China's surge was accompanied by high volatility (coefficient of variation of 0.31), and a price shock was detected in imports from Turkey around 2022 (abnormality score 53.7, +28.5% price shift), likely linked to the post-pandemic surge in global commodity and energy prices.
Import concentration decreased, indicating a more diversified supply base
The Herfindahl-Hirschman Index (HHI) for EU imports by value fell from 1,239 to 1,073 (−13.4%) over the period. While this still reflects moderate concentration, the downward trend suggests that the EU has been successful in broadening its import sources rather than becoming more dependent on a small number of suppliers. By contrast, export concentration remained very low (HHI around 525–534), consistent with a highly diversified customer base spanning dozens of countries.
3. Eroding Trade Surplus and Growing Exposure: The EU's Evolving Competitive Position
The net export surplus barely grew despite a 49% rise in export values
Despite the strong export value performance, the EU's trade surplus in CN 3917 expanded only modestly — from €1.80 billion to €1.90 billion (+5.5%) — because import growth (+94.6% in value) far outstripped export growth (+49.1%). The surplus reached its peak around 2022 (€2.10 billion) before declining in the most recent years.
| Year | Export value (€ bn) | Import value (€ bn) | Balance (€ bn) |
|---|---|---|---|
| 2015 | 3.52 | 1.72 | 1.80 |
| 2020 | 4.58 | 2.22 | 2.36 |
| 2022 | 5.34 | 3.24 | 2.10 |
| 2025 | 5.24 | 3.34 | 1.90 |
Net import reliance deepened, though the EU remains a net exporter
The net import reliance indicator — which measures the trade balance relative to apparent consumption — moved from −4.3% to −13.7% over the period (negative values indicate a net exporter position). While a negative value is favourable (the EU exports more than it imports), the deepening of this figure actually reflects the faster growth of imports relative to the domestic market, not a strengthening of export capacity. The most negative point was reached around 2020–2021 (−18.9%), after which a partial recovery occurred.
Trade intensity and export propensity both surged, reflecting the sector's global orientation
Two key indicators confirm the increasing openness of the EU plastic pipes sector:
- Trade intensity (total extra-EU trade as a share of production value) rose from 22.2% to 41.3% (+86.2%).
- Export propensity (exports as a share of production value) increased from 14.3% to 30.4% (+113.5%).
The export propensity score (133.1) is flagged as the most salient indicator, meaning the EU's orientation towards external markets has grown faster than its overall trade integration. This suggests that EU manufacturers are increasingly targeting non-EU markets as a growth channel, possibly as domestic construction cycles have moderated or as EU producers have gained competitiveness in higher-value product niches.
Trade intensity · Export propensity
Italy and Czechia stand out as specialised EU producers; Germany dominates in absolute terms
An analysis of revealed comparative advantage (RCA) and specialisation (RSCA) for 2025 shows that:
| Member State | RSCA | RCA | Export share |
|---|---|---|---|
| Cyprus | 0.63 | 4.39 | 0.1% |
| Estonia | 0.31 | 1.90 | 0.3% |
| Latvia | 0.25 | 1.66 | 0.3% |
| Italy | 0.20 | 1.51 | 12.1% |
| Czechia | 0.17 | 1.41 | 6.8% |
| Germany | — | — | 37.6% |
Germany alone accounts for 37.6% of extra-EU exports (€1.76 billion in 2025) and 25.2% of extra-EU imports (€841 million), making it the central node in the EU's plastic pipe trade. Italy and Czechia, while smaller in absolute terms, show the strongest specialisation profiles, suggesting these countries have developed competitive clusters in pipe and fitting manufacturing.
Conclusion
The EU's external trade in plastic pipes and fittings (CN 3917) over 2015–2025 is characterised by a paradox: strong nominal value growth coexisting with fundamentally shifting structural dynamics. Export values rose by 49%, but this was entirely a price effect — volumes were flat. Import values nearly doubled, driven by a genuine 77% volume increase, with rigid polyethylene pipes and flexible reinforced hoses accounting for much of the surge.
The EU retains a comfortable trade surplus (€1.9 billion in 2025) and its domestic production base has expanded strongly (+94% in value). However, the faster pace of import growth means that the sector's trade surplus is eroding in relative terms, and the net import reliance indicator has moved deeper into negative territory. Import sources have diversified (lower HHI), but the emergence of China, Turkey, and Serbia as high-growth suppliers introduces new competitive and geopolitical considerations.
Looking ahead, the EU's continued role as a net exporter will depend on its ability to maintain price competitiveness in higher-value product segments (fittings, flexible hoses) while managing the cost pressures that have driven unit prices up by over 50% in a decade. The loss of the Russian market and the rapid growth of US-bound exports highlight the sector's sensitivity to geopolitical realignment. For policymakers, the key question is whether the import surge in basic infrastructure piping (especially rigid PE pipes) signals a lasting shift in the EU's comparative advantage — away from commodity-grade pipes and towards more specialised, higher-margin products.
