Market evolution: Putty and sealants (CN 32141010) — 2015–2025

Introduction

This report examines the EU's extra-EU trade in glaziers' putty, grafting putty, resin cements, caulking compounds and other mastics (CN 32141010) over the period 2015–2025. The EU is a major net exporter of these products, with a trade surplus that widened from roughly €1.0 billion in 2015 to €1.1 billion in 2025. Behind that headline stability, however, the decade brought remarkable structural shifts: volumes moved in opposite directions for exports and imports, prices surged, key geopolitical events re-routed trade flows, and EU domestic production expanded dramatically. The following three sections unpack these dynamics.

1. A Value Story: Rising Revenues Mask a Divergence Between Export and Import Volumes

EU export revenues grew while tonnages declined

Over the full period, the value of EU extra-EU exports rose by 23.9%, from €1.24 billion to €1.53 billion. In stark contrast, the quantity exported fell by 14.0%, from 372,937 tonnes to 320,743 tonnes. The reconciling factor is a 44.0% increase in unit export prices, which climbed from €3,320/t to €4,782/t. This indicates that the EU's export growth was overwhelmingly a price-driven phenomenon, not a volume one.

EU imports rose on both value and volume

By contrast, imports grew on both dimensions: value surged 63.7% (from €239.5 million to €392.1 million), and quantity expanded 41.7% (from 68,887 tonnes to 97,606 tonnes). Import prices rose more modestly, at 15.5% (from €3,477/t to €4,017/t). Notably, in 2015 import and export unit values were close to parity; by 2025, a significant gap had opened, with EU exports commanding a €765/t premium over imports—consistent with the EU increasingly exporting higher-value formulations while importing more commoditised products.

The EU's trade surplus widened modestly despite import growth

The trade balance remained firmly positive throughout, growing from €999 million to €1,142 million (+14.3%). The net import reliance deepened from −29% to −85%, meaning the EU is not only self-sufficient but increasingly oriented towards external markets. At its trough (around 2022–2023), the ratio reached −125%, indicating that the EU's extra-EU export surplus was at that point larger than total imports—a particularly strong net-exporter position.

2. Geopolitical Realignments Reshaped the EU's Partner Landscape

The collapse of EU exports to Russia is the decade's defining shock

The single most dramatic change in EU trade flows was the near-total evaporation of exports to the Russian Federation. From €170 million in 2015, exports to Russia collapsed to just €144,005 in 2025—a decline of 99.9%. The volatility analysis detected two distinct shocks: a price shock centred in 2023 (with an abnormality score of 99.5 and a +1,207% price shift, reflecting the near-total loss of regular trade flows leaving only residual high-priced transactions) and a complete supply-side shock in 2025 (−100% in volume). This trajectory aligns with the progressive tightening of EU sanctions on Russia following the 2022 invasion of Ukraine. Russia had been the EU's second-largest non-EU export destination for this product in 2015; its effective removal from the picture required a significant reorientation of EU exporters.

The United States and Türkiye filled part of the gap

Two partners absorbed a substantial share of the redirected export capacity:

The US became the EU's top non-EU export market by value in 2025, overtaking the United Kingdom (which had held that position in 2015). Saudi Arabia also remained a stable, sizeable destination (~€51 million in 2025), while Ukraine grew from €21 million to €32 million.

The import side saw the rise of Türkiye, China, and Serbia

On the import side, the most striking growth came from three suppliers:

Switzerland remained the largest supplier by far (€164 million in 2025, +23.3%), likely reflecting its chemical industry and geographic proximity. The United Kingdom also grew sharply as an import source (+182.8% to €91 million), potentially linked to post-Brexit trade recording changes. Meanwhile, Norway—a formerly significant supplier—saw imports decline by 44.0%.

Germany anchors both sides of intra-EU extra-EU trade

Among EU Member States, Germany was by far the dominant actor: it accounted for €697 million in extra-EU exports in 2025 (45% of the EU total) and €166 million in extra-EU imports. Belgium, France, and the Netherlands were the next-largest exporters, while France (+362%) and Ireland (+258%) saw the fastest import growth among major reporters—suggesting growing reliance on non-EU supply in those markets.

3. A Manufacturing Base in Expansion with Growing Openness

EU production of putty and sealants surged over the decade

According to PRODCOM production data, EU production of CN 32141010 goods grew from 516 million kg to 830 million kg in volume (+60.8%) and from €1.04 billion to €2.67 billion in value (+155.5%). The value growth outpacing the quantity growth by a factor of nearly 2.5× confirms the price-upgrading trend observed in trade data: European manufacturers are producing and selling increasingly higher-value formulations.

Export propensity and trade intensity both rose sharply

The export propensity (extra-EU exports as a share of domestic production) increased from 37.5% to 61.3% (+63.6%), while trade intensity (total extra-EU trade as a share of production) rose from 45.6% to 66.5% (+45.7%). This means that the EU's putty and sealant sector has become substantially more internationally oriented over the decade—not only producing more, but selling a much larger share of output on non-EU markets. The salience analysis flags export propensity as the most prominent vulnerability indicator, reflecting the sector's growing dependence on external demand.

Import-source concentration fell while export-destination concentration held steady

The Herfindahl-Hirschman Index (HHI) for imports fell by 25.4% (from 3,491 to 2,606 by value, and by 35.8% by volume), indicating a meaningful diversification of import sources. This is consistent with the rise of Türkiye, China, and Serbia as new suppliers. By contrast, export destination concentration remained low and broadly stable (HHI around 670–700), reflecting the EU's already diversified customer base—though the loss of Russia and the growth of the US slightly re-weighted the distribution.

Specialisation is concentrated in a handful of smaller Member States

The revealed comparative advantage analysis for 2025 shows that the most specialised EU exporters of putty and sealants are Estonia (RSCA 0.75, RCA 6.93), Latvia (RSCA 0.55, RCA 3.40), and Belgium (RSCA 0.42, RCA 2.45). However, in absolute terms, Germany—despite a more moderate RCA of 1.51—dominates production volume (31.9% of EU production). This pattern suggests that while small Baltic and Benelux economies have developed niche specialisation, the industry's scale is driven by the large Western European economies.

Conclusion

The EU's putty and sealant market (CN 32141010) over 2015–2025 tells a story of structural resilience amid significant external shocks. The EU consolidated its position as a major net exporter, with production growing by over 60% in volume and over 150% in value, while export unit prices increased by 44%—evidence of a shift towards higher-value-added formulations. Geopolitically, the loss of the Russian market (−99.9% in exports) was the defining event of the period, but EU producers successfully redirected flows to the United States, Türkiye, and other markets. On the import side, source diversification increased, with Türkiye, China, and Serbia emerging as fast-growing suppliers alongside the established Swiss hub. The sector's rising export propensity (from 37% to 61% of production) signals both strength and growing exposure to international demand cycles—a vulnerability worth monitoring, even as the EU's broad geographic diversification of export destinations provides a natural buffer against partner-specific shocks.
