Market evolution: Plastic sheets (CN 3921) — 2015–2025

Introduction

CN 3921 covers a broad and heterogeneous family of plastic semi-finished products — including cellular plastic sheets (styrene, PVC, polyurethane), reinforced or laminated plastic plates, and films combined with other materials. Excluded are self-adhesive products and floor/wall coverings (CN 3918). Within the EU's plastics sector, heading 3921 is a bundling category that aggregates six subheadings, from cellular styrene foams (392111) to the catch-all reinforced/laminated segment (392190), which alone accounts for roughly 60 % of total trade value in this heading.

Over the 2015–2025 period, the EU maintained a persistent and substantial trade surplus in CN 3921 — its net-exporter position deepening slightly from a surplus of €1.71 billion in 2015 to €1.76 billion in 2025. Yet behind this headline stability lies a far more turbulent decade, marked by a structural price shock in 2022, a dramatic collapse in EU–Russia trade, and a rapid rise in Asian suppliers. This report examines three major dynamics that shaped the market during this period. Overview

A surplus sustained by rising prices rather than volume growth

Export values rose while volumes stagnated

The most striking macro-level feature of the EU's CN 3921 trade is the widening gap between value and volume trends. Between 2015 and 2025, EU extra-EU exports grew by 23.2 % in value (from €3.34 billion to €4.11 billion), but only by 1.1 % in quantity (from 695,235 t to 702,586 t). The average export unit value climbed from €4,799/t to €5,851/t (+21.9 %). In other words, virtually the entire value expansion was price-driven. Overview

Imports grew in both dimensions, but price inflation dominated

EU imports rose more vigorously: value surged by 44.3 % (from €1.63 billion to €2.35 billion) and volume by 29.3 % (from 403,239 t to 521,311 t). The import unit value increased by 11.6 % (from €4,045/t to €4,513/t). Imports thus captured market share in volume terms, but even here, a significant fraction of the value increase reflects higher unit prices rather than additional tonnage.

Domestic production mirrored the same pattern

EU domestic production data confirms the price-driven character of growth. Production quantity rose by 30.9 % (from 3.53 billion kg to 4.62 billion kg), while production value leapt by 73.2 % (from €9.92 billion to €17.18 billion). The implied production price therefore rose from roughly €2,810/t to roughly €3,720/t over the period — a 32 % increase. This aligns with the broader narrative of plastics processors facing sustained input-cost inflation. Production volumes

The 2022 energy-price shock as a structural turning point

Prices surged across all subheadings in 2022

The year 2022 stands out as the sharpest inflection point in the decade. Triggered by the post-pandemic commodity supercycle and amplified by the energy crisis following Russia's invasion of Ukraine, unit values spiked across virtually every CN 3921 subheading.

The reinforced/laminated segment (392190), which represents the bulk of trade, saw import unit values jump from €3,921/t in 2021 to €4,667/t in 2022 (+19 %), and export prices from €4,707/t to €5,681/t (+21 %). The spike was even more pronounced in certain cellular subsegments.

Cellular plastics (392119) experienced an extreme and prolonged price escalation

The most dramatic price dynamic occurred in CN 392119 — other cellular plastics (excluding styrene, PVC, polyurethane, and regenerated cellulose). Import unit values in this subheading nearly tripled over the decade:

While import volume fell by 43 % (from 61,235 t to 34,877 t), import value actually rose by 36 % (from €300 million to €409 million). This combination of collapsing volumes and surging prices is consistent with a compositional shift toward higher-specification specialty products — or with supply constraints affecting specific resin types within this residual subheading. By contrast, the EU's exports in this segment grew in both volume (+10 %) and value (+48 %), suggesting that EU producers were able to command premium prices for their output. Overview

Specific price shocks were detected in 2022 for key partners

Statistical shock detection confirms the singularity of the 2022 episode. The three largest detected price shocks in the dataset all centre on 2022:

Switzerland — a major bilateral partner — recorded the most abnormal import price increase, likely reflecting the transit role of Swiss intermediaries in channeling raw-material cost increases. The Türkiye shock points to energy-driven cost pass-through from a country whose plastics sector is heavily reliant on natural gas. The Ukraine export shock reflects wartime disruption and exchange-rate volatility. Supply shocks

Partial normalisation by 2024–2025, but pre-crisis levels were not recovered

By 2025, prices had partially retreated from their 2022–2023 peaks. The export price for 392190 settled at €5,545/t — still 18 % above the 2015 level. The import price for 392119 came down to €11,716/t from its €14,500/t peak, but remained 2.4 times the 2015 level. This suggests that while the acute energy shock passed, a permanent upward shift in cost structures had occurred.

A dramatic reorientation of trade geography

Russia collapsed as an export destination

The most politically significant change in the decade was the near-total cessation of EU exports to Russia. From €209 million in 2015 (and a peak of €228 million in 2018), EU exports to Russia in CN 3921 fell to just €36 thousand in 2025 — a decline of effectively 100 %. This reflects the impact of EU sanctions imposed in 2022 following Russia's invasion of Ukraine. Russia's volatility coefficient (0.84) is by far the highest among all import partners, underscoring the abruptness of the rupture. Partners

Asian suppliers rapidly filled the gap on the import side

While Russia disappeared as a buyer, Asian producers dramatically expanded their presence as suppliers to the EU:

China's import value more than doubled, making it the EU's single largest extra-EU supplier in 2025. Türkiye's rise is consistent with its growing role as a plastics-processing hub bridging European and Asian supply chains. India and South Korea also doubled their shipments, pointing to a broader geographic diversification — or perhaps a growing cost competitiveness of Asian producers relative to European ones.

The United States emerged as the EU's top export growth market

On the export side, the United States replaced Russia as the EU's most dynamic growth partner. EU exports to the US grew by 65.9 % (from €525 million to €871 million), making the US the second-largest destination after the United Kingdom. Exports to the UK — the EU's top partner — grew modestly by 2.9 %, essentially stagnating in real terms. The US growth likely reflects strong demand from American construction and packaging sectors, as well as the relative price competitiveness of EU specialty products.

Import-source concentration fell, suggesting diversification

The Herfindahl–Hirschman Index (HHI) for import concentration by value declined from 1,334 to 1,130 (–15.3 %), indicating a shift away from dependence on a small number of suppliers. Export concentration remained broadly stable (HHI around 994 to 974, –2.1 %). The diversification of import sources is partly a consequence of the surge in Turkish, Indian, and Korean supply, which diluted the historical dominance of Switzerland and the United Kingdom. Concentration

Within the EU, Central European members gained import weight

Among EU member states, the most striking intra-EU shift was the rapid growth of Central European importers. Poland's extra-EU imports rose by 133.6 % (from €92 million to €214 million), and Hungary's by an extraordinary 514.1 % (from €23 million to €141 million). Both countries benefited from their integration into automotive and electronics supply chains, which are major end-use sectors for plastic sheets and films. Germany remained the EU's dominant trader — accounting for €569 million in imports and €1.3 billion in exports in 2025 — but its growth rates were modest compared to its eastern neighbours.

Conclusion

The EU's trade in CN 3921 over 2015–2025 tells a story of apparent macroeconomic stability masking profound structural transformation. The headline figures — a persistent surplus of roughly €1.7–1.8 billion — barely changed. Beneath them, however, volumes diverged from values, the 2022 energy crisis permanently reset pricing benchmarks across nearly all subheadings, and the map of trade partners was redrawn by geopolitical events.

Three takeaway themes emerge. First, price inflation rather than volume expansion drove value growth: EU export tonnage rose by barely 1 %, while export values grew by 23 %, pointing to a mature market where European producers increasingly compete on specification and quality rather than scale. Second, the 2022 commodity and energy shock left a lasting imprint: unit values in cellular plastic subsegments tripled over the decade, and even after partial normalisation, prices remain well above pre-2020 levels. Third, the trade geography was fundamentally reshaped: Russia's exit as a buyer, China's and Türkiye's rise as suppliers, and the growing import role of Central European EU members all reflect a market adapting to sanctions, supply-chain reconfiguration, and shifting cost competitiveness.

Looking ahead, the continued increase in trade intensity (from 23 % to 34 % of production) and export propensity (from 17 % to 24 %) suggests the EU's CN 3921 sector is becoming more exposed to global market conditions — a vulnerability that the 2022 shock demonstrated can materialise rapidly and with lasting consequences.
