Market evolution: Polyvinyl chloride (CN 3904) — 2015–2025

Introduction

CN 3904 covers Polymers of vinyl chloride or of other halogenated olefins, in primary forms, a broad heading that encompasses not only polyvinyl chloride (PVC) in its various formulations but also vinyl chloride copolymers, vinylidene chloride polymers, and fluoropolymers such as PTFE. This product family is central to the European chemicals and plastics sector, serving the construction, automotive, packaging, electronics, and medical industries.

Over the 2015–2025 decade, EU trade in CN 3904 was shaped by three intertwined dynamics: a dramatic price spike in 2021–2022 driven by energy costs and post-pandemic supply disruptions; a structural decline in export volumes partially offset by rising imports; and a fundamental reshuffling of trade partners triggered by geopolitical events, above all the sanctions imposed on Russia and the growing competitive weight of Asian suppliers. This report examines each of these dynamics in turn, drawing exclusively on the trade data provided.

The 2021–2022 price surge and its uneven legacy

Unit values more than doubled at the peak before partially retreating

The most striking feature of the 2015–2025 period is the extreme price volatility concentrated in the 2021–2022 window. EU export unit values rose from a floor of €1,173/t in 2016 to a peak of €2,492/t in 2022—an increase of 112%—before falling back to €1,582/t by 2025. Import prices followed a similar arc, climbing from €1,427/t to a maximum of €2,668/t before settling at €1,763/t. The spike was fuelled by the combination of surging post-COVID demand, severe supply-chain bottlenecks, and—critically for an energy-intensive product whose chlorine feedstock depends on electrolysis—the explosion of European natural-gas prices in 2021–2022.

By 2025, prices had normalised well below their peaks but remained above the 2015 starting point—export prices were still 29% higher and import prices 5% higher than a decade earlier. The trade dashboard overview shows that the value surge was sufficient to push total EU CN 3904 export value to a record €3.71 billion in 2022, even though physical volumes had already begun their structural decline.

The largest price shocks hit export flows to Turkey, Algeria, and the United States

The shock-detection analysis confirms that the price spike was not evenly distributed across partners. The three most significant supply-shock events were all export-side price shocks centred on the 2021–2022 period:

Turkey, the EU's single largest CN 3904 export market, saw unit values jump by 91% in a single year—an extraordinary dislocation that likely reflected both the pass-through of European energy surcharges and Turkey's own currency depreciation, which raised import costs in euro terms. The US shock in 2022, though smaller in magnitude, was significant given that the United States accounted for 17.4% of export value. These shocks were transitory: by 2025, prices to all three markets had largely retraced, though not to pre-spike levels.

Volatility remained elevated for several import partners throughout the decade

Beyond the headline spike, the coefficient of variation across the full 2015–2025 period reveals that some import relationships were inherently more volatile than others. Taiwan (CV 1.73), Ukraine (CV 1.34), and South Korea (CV 1.25) exhibited the highest import-value volatility—far above the more stable flows from Mexico (CV 0.19), Norway (CV 0.22), and Switzerland (CV 0.14). On the export side, the most stable relationships were with Switzerland (CV 0.09), the United Kingdom (CV 0.10), and Serbia (CV 0.11), reflecting deep, long-standing trade ties that proved resilient even through the turbulence of 2021–2022.

Declining volumes reveal a structural shift beneath the surface

EU export quantities fell by a fifth while import volumes expanded by over 40%

While the value data paint a picture of modest growth—EU CN 3904 exports rose 2.7% in value over the decade—the underlying volume story is one of contraction. Export quantities fell from 1,830 kt in 2015 to 1,457 kt in 2025, a decline of 20.3%. Over the same period, import quantities grew from 460 kt to 652 kt (+41.6%), and import values rose from €774 million to €1.15 billion (+48.5%). The EU's trade surplus in CN 3904 accordingly narrowed from €1.47 billion to €1.16 billion (–21.4%).

This divergence—stable or rising values paired with declining physical volumes—is the hallmark of a market where price inflation masked a genuine loss of competitive volume. The product-level breakdown confirms that the decline was concentrated in standard PVC: exports of CN 390410 (uncompounded PVC) fell from 1,418 kt to 1,096 kt (–22.7%), accounting for the bulk of the overall volume loss.

Domestic production contracted sharply in volume, suggesting a structural rationalisation

The decline in export volumes was accompanied by a significant contraction in EU production volumes. CN 3904 production fell from 8,423 kt in 2015 to 5,977 kt in 2025—a drop of 29.0%. Remarkably, production value was virtually unchanged over the same period (€7.62 billion in both years), implying that the EU's remaining output shifted decisively towards higher-value, more specialised grades.

This pattern is consistent with a European PVC industry that is progressively exiting bulk commodity grades—where it faces a structural energy-cost disadvantage relative to the United States (cheap ethane) and the Middle East—and concentrating on higher-margin speciality products such as fluoropolymers and engineered copolymers.

Rising trade intensity and export propensity point to deeper global integration

Despite the volume decline, the EU's trade intensity (the share of total apparent absorption accounted for by trade) rose from 27.8% to 44.0% (+57.9%), while export propensity (exports as a share of production) climbed from 21.9% to 35.3% (+61.4%). In other words, even as the absolute size of the EU's CN 3904 sector shrank, it became more dependent on—and engaged with—international markets.

This increasing openness coexists with a strengthening of the EU's net export position relative to the now-smaller production base: net import reliance moved from –15.8% to –24.9%, meaning the EU remained a net exporter but by a wider margin relative to its own output. The paradox—a shrinking sector that is simultaneously more export-oriented—is explained by the fact that production volumes fell faster (–29%) than export volumes (–20%), so exports grew as a share of the reduced domestic base.

Geopolitical realignment reshapes the EU's trade geography

The collapse of EU–Russia PVC trade after 2022 is the decade's most dramatic partner shift

The most visible consequence of the Russia-Ukraine conflict and the subsequent sanctions regime was the near-total evaporation of EU CN 3904 exports to Russia. Exports to the Russian Federation fell from €162 million in 2015 to just €12.6 million in 2025, a decline of 92.2%. Russia was the EU's fourth-largest extra-EU export market in 2015; by 2025 it had fallen to a marginal position. The loss was absorbed partly through diversion to alternative markets—the United Kingdom, the United States, and Switzerland all saw increases—but the absolute volumes lost to Russia were not fully replaced.

Asian suppliers filled the expanding import gap

On the import side, the most striking shifts involved Asian producers. EU imports from China grew from €67 million to €213 million (+216.6%), while imports from South Korea surged from €10 million to €124 million (+1,110%). China's rise was steady and volume-driven; Korea's was more recent and dramatic, with the Republic of Korea becoming the EU's fifth-largest CN 3904 supplier by value in 2025.

By contrast, some traditional suppliers lost ground:

Egypt's near-total disappearance from EU import statistics (from €20 million to €10,523) is notable and may reflect the disruption of Egyptian PVC capacity or a loss of competitiveness. The decline of the United Kingdom as an import source (–18.5%) may partly reflect post-Brexit trade friction, even as the UK grew as an export destination for EU producers (+26.0%).

Import sources diversified while export markets became slightly more concentrated

The Herfindahl-Hirschman Index (HHI) of import concentration fell from 1,416 to 1,093 (–22.8%), moving from moderate concentration towards a more diversified supply base. This reflects the rise of China and Korea alongside the continued presence of the US, Mexico, and the UK. Export concentration moved in the opposite direction, with the HHI rising modestly from 850 to 939 (+10.4%), as flows became somewhat more focused on a handful of key markets—Turkey, the UK, and the US together accounted for the largest share.

Within the EU, production and trade hubs shifted westward and southward

The member-state breakdown reveals significant internal redistribution. On the import side, Germany (€118M → €264M, +124%), Italy (€126M → €244M, +94%), and especially Poland (€10M → €66M, +579%) saw large increases, while Belgium (€215M → €185M, –14%) and the Netherlands (€66M → €49M, –26%) contracted. On the export side, France emerged as the EU's most specialised CN 3904 exporter (RSCA 0.49, RCA 2.93), overtaking Portugal (RSCA 0.46, RCA 2.73), while Germany—despite holding the largest production share at 25.8%—showed a more modest specialisation index (RSCA 0.10). Traditional exporters like Germany (–15%) and Belgium (–11%) saw their extra-EU export values decline, while France (+69%), Italy (+24%), and the Netherlands (+55%) gained ground.

Conclusion

The EU's CN 3904 market over 2015–2025 is a story of divergence between surface-level stability and deep structural change. In value terms, exports barely grew (+2.7%) and the trade surplus, while still substantial at €1.16 billion, shrank by a fifth. Beneath those headline figures, however, physical export volumes fell by 20%, domestic production contracted by 29%, and the EU's import needs grew by over 40%. The extreme price spike of 2021–2022—driven by the European energy crisis and global supply disruptions—temporarily inflated values and masked the volume decline, but prices have since normalised at levels only modestly above the pre-spike baseline.

The period also witnessed a fundamental reshaping of the EU's trade geography. The collapse of exports to Russia (–92%) and the rise of Asian suppliers—notably China (+217%) and South Korea (+1,110%)—represent the most dramatic shifts. Meanwhile, the EU's fluoropolymer segments (CN 390461 and 390469) grew to account for nearly half of import value by 2025, while vinylidene chloride polymers (CN 390450) emerged as a fast-growing export niche, rising from €19 million to €161 million in value. These shifts suggest an industry that is gradually pivoting away from commodity PVC—where it faces a structural cost disadvantage—towards higher-value speciality polymers, even as it becomes more reliant on global supply chains for its import needs.
