Market evolution: calcined gypsum plasters (CN 252020) — 2015–2025

Introduction

This report analyses the evolution of the European Union's external trade in plasters consisting of calcined gypsum or calcium sulphate (CN 252020) over the period 2015–2025. Despite belonging to a low-profile commodity segment, this product plays a vital role in the construction sector and certain industrial applications (e.g. dental, textile and paper finishing). The period under review spans a decade marked by significant disruptions — including the COVID-19 pandemic, the energy-price crisis, and geopolitical reconfigurations following the Russia-Ukraine conflict — all of which have left observable imprints on trade flows, pricing structures and partner relationships. Based on the available data, three main dynamics emerge: a pronounced price-volume divergence between exports and imports; a significant geographic reorientation of trade partners; and a declining domestic production base that is partially offset by a growing import reliance on selected suppliers. Each of these themes is examined in detail below.

1. A market increasingly driven by price rather than volume

The most striking feature of the 2015–2025 period is the divergence between trade values and trade volumes. While the EU's total export value in CN 252020 grew by 19.9% (from €64.9 million to €77.8 million), the underlying quantity shipped abroad fell by 40.1% (from 611,858 tonnes to 366,328 tonnes). Conversely, import volumes more than doubled (+100.7%), rising from 109,550 to 219,827 tonnes, yet import values grew by only 24.2% (from €20.7 million to €25.7 million). These opposing trajectories point to a fundamental repricing of the product on both sides of the trade balance.

1.1. Export prices doubled while import prices nearly halved

In 2015, EU exporters were selling at an average price of €106 per tonne — well below the import price of €189 per tonne. By 2025, this relationship had inverted dramatically: exports commanded €212 per tonne, nearly double the import price of €117 per tonne (see General Overview). This suggests that the EU increasingly specialised in higher-value or more processed plaster products for export, while simultaneously sourcing more commoditised or bulk-grade material from lower-cost third-country suppliers. The energy-price surge of 2021–2022 likely contributed to higher EU production costs and export prices, but the sustained nature of the price differential by 2025 indicates structural rather than merely cyclical factors at play.

1.2. The EU remains a consistent net exporter, but the trade surplus is value-driven

The EU has maintained a positive trade balance in CN 252020 throughout the entire period. The surplus grew from €44.2 million in 2015 to €52.2 million in 2025 (+17.9%), with a trough of €34.1 million around the midpoint of the period (General Overview). Crucially, the net export reliance — measured as a percentage of domestic production — remained negative (indicating net exporter status) throughout, but deepened from −3.5% to −5.4% (Net import reliance). This confirms that the EU's competitive advantage in this product is not merely nominal but reflects a consistent ability to generate a surplus even as the composition of trade shifts.

1.3. Trade intensity and export propensity both increased substantially

The trade intensity of CN 252020 rose from 6.2% to 10.7% over the period, while export propensity climbed from 4.8% to 8.1%. These figures indicate that an increasing share of EU production (or consumption) in this category is channelled through international trade. This rising openness may reflect the commoditisation of standard-grade plasters (increasingly imported) alongside a growing export orientation for specialised or higher-specification products.

2. Geographic reorientation: Western partners gain, former key markets collapse

The period 2015–2025 witnessed a dramatic reshaping of the EU's trade geography in calcined gypsum plasters. Some traditional export markets contracted sharply, while certain partner countries emerged as major new import sources. The net effect is a partial pivot of the EU's external trade towards its immediate Western neighbourhood (particularly the United Kingdom and Switzerland) and, on the import side, towards North Africa and the Western Balkans.

2.1. The United Kingdom and Switzerland consolidated as the EU's dominant export markets

By 2025, the UK and Switzerland together accounted for roughly €49.5 million of EU exports — approximately 64% of total export value. The UK market nearly doubled in value terms over the decade, likely benefiting from post-Brexit trade reconfiguration and the UK's continued reliance on EU-origin construction materials (Top partners). Switzerland's growth was similarly robust. Both markets are characterised by high GDP per capita, strong construction activity, and geographic proximity to major EU producers.

2.2. Exports to Russia and Nigeria collapsed

The decline in exports to Russia is almost certainly linked to the successive rounds of EU sanctions imposed from 2014 onwards and the dramatic worsening of EU-Russia trade relations following the 2022 full-scale invasion of Ukraine. Nigeria's decline, while less politically explicable, may reflect changing competitive dynamics in West Africa or shifting procurement patterns (Top partners).

2.3. Morocco emerged as a fast-growing import source, alongside sustained supplies from the UK and Türkiye

On the import side, Morocco stands out with a nearly fivefold increase in value. The country's growing gypsum mining and processing capacity, combined with competitive labour and energy costs and proximity to Southern European markets, likely underpin this surge. Türkiye also maintained its position as a significant supplier, while Western Balkan countries (North Macedonia, Bosnia and Herzegovina) expanded their presence. The United Kingdom remained the single largest import partner by value, reflecting the deep bilateral integration in construction materials post-Brexit (Top partners).

2.4. Export concentration increased significantly while import concentration evolved differently

The Herfindahl-Hirschman Index (HHI) for exports by value rose from 1,177 to 2,104 (+78.8%), indicating a substantial increase in market concentration — i.e., EU exports became more dependent on a smaller number of destination countries (Concentration). This mirrors the geographic consolidation around the UK and Switzerland described above. For imports, the value-based HHI declined modestly (from 2,065 to 1,782, −13.7%), suggesting a slight diversification of supply sources. However, import concentration by volume increased dramatically (from 2,345 to 4,612, +96.6%), pointing to the emergence of a few large-volume, low-price suppliers (likely Morocco and Türkiye) dominating the quantitative intake.

3. A contracting production base with evolving intra-EU specialisation

Beneath the trade-level dynamics lies a notable decline in EU domestic production of CN 252020, which has implications for the bloc's long-term supply security and competitive positioning.

3.1. EU production volumes fell sharply while values held relatively steady

EU production of calcined gypsum plasters contracted by 42.5% in volume terms between 2015 and 2025, falling from approximately 9.7 million tonnes to 5.6 million tonnes. Yet the production value declined by only 5.7%, implying a near-doubling of the average domestic production price. This is consistent with the export price dynamics discussed in Section 1 and suggests that EU producers have shifted their product mix towards higher-value-added plaster formulations, possibly including specialised construction plasters, dental plasters, or industrial-grade products, while lower-margin bulk plasters are increasingly sourced from abroad.

3.2. Germany, France and Ireland dominate EU exports, but with divergent trajectories

Germany was by far the largest EU exporter throughout the period, accounting for nearly half of EU exports by value in 2025 (Top reporters). The Netherlands exhibited a spectacular increase (+1,312.9%), potentially reflecting its role as a re-export or logistics hub rather than a primary producer. Poland and Italy, by contrast, saw their export values halve, suggesting a loss of competitiveness or a reallocation of production capacity. France, the second-largest producer by specialisation indices (RSCA of 0.60, RCA of 4.05), nonetheless experienced a 16.8% decline in export value, hinting at domestic market pressures or shifting trade flows within the EU single market.

3.3. Latvia and France showed the strongest revealed comparative advantage

According to the 2025 specialisation data (Market Structure), Latvia exhibited the highest normalised RCA (RSCA of 0.86, RCA of 13.3), though this is based on a very small absolute share of EU production (4.4%). France, with a more substantial 31.7% production share, had an RSCA of 0.60 and RCA of 4.05, indicating genuine and economically meaningful specialisation. Germany and Spain, despite being major producers, showed only moderate RSCA values (0.24 each), suggesting that gypsum plasters represent a relatively balanced — rather than specialised — segment of their industrial output. At the other end of the spectrum, Belgium, Finland and Ireland displayed negative RSCA values, confirming that their export activities in this product are negligible relative to their overall trade profiles.

3.4. Export price shocks were concentrated in developing-country markets

The volatility analysis identified several extreme price shock events in EU exports, all directed towards developing or emerging-economy markets:

While these events represent small volumes in absolute terms (value shares of 0.3% to 2.0%), their magnitude is extraordinary. Such spikes may reflect one-off contract effects, currency fluctuations, or the shipment of small quantities of highly specialised (e.g. dental or technical-grade) plasters at premium prices. The Senegal and Côte d'Ivoire shocks coincided with the COVID-19 pandemic period, when supply-chain disruptions could have amplified price volatility in African markets.

Conclusion

Over the decade 2015–2025, the EU's trade in calcined gypsum plasters (CN 252020) underwent a quiet but significant transformation. The bloc consolidated its position as a net exporter, growing its trade surplus to €52.2 million, but this achievement masked a structural shift: export volumes fell by 40% even as values rose by 20%, driven by a doubling of unit export prices. In parallel, import volumes doubled while import prices declined, indicating that the EU increasingly relies on third-country suppliers for lower-grade, bulk plasters while channelling its domestic production towards higher-value applications.

Geographically, trade flows polarised towards the EU's Western periphery — the United Kingdom and Switzerland together absorbed nearly two-thirds of EU exports by 2025 — while exports to Russia and Nigeria collapsed. On the import side, Morocco emerged as a rapidly growing supplier, joining the United Kingdom and Türkiye as the three largest sources of incoming plaster shipments.

Domestically, EU production volumes fell by over 40%, though production values proved more resilient, consistent with a shift towards higher-value product segments. Germany anchored the export side, accounting for nearly half of EU exports by value, while the Netherlands emerged as a surprisingly large exporter (possibly reflecting re-export dynamics). The growing trade intensity (from 6.2% to 10.7%) and export propensity (from 4.8% to 8.1%) confirm that this once relatively insular commodity market has become increasingly integrated into international trade flows. For policymakers and industry stakeholders, these trends suggest that the EU's competitive edge in gypsum plasters lies increasingly in quality and specialisation rather than volume — a positioning that carries both opportunities and vulnerabilities in a market subject to energy-price swings and geopolitical realignment.
