Market evolution: Granite and building stone (CN 2516) — 2015–2025

Introduction

This report analyses the EU's external trade in granite, porphyry, basalt, sandstone, and other monumental or building stone (CN 2516) from 2015 to 2025. Over this decade, the EU has undergone a profound structural shift, moving from a position of significant import dependency to one of near self-sufficiency and increased export competitiveness. Total imports in value fell by 37.3%, while export value decreased by a more modest 11.7%. Most strikingly, the EU's net import reliance collapsed from 44.0% to 9.8%, indicating a fundamental rebalancing of the market. This period was characterized by declining volumes from traditional suppliers, a sharp contraction in trade intensity, and the emergence of a more diversified and resilient trade structure.

1. The Great Rebalancing: From Dependency to Autonomy

The most significant dynamic in the EU's building stone market is the radical reduction in external dependence. This shift was driven by a surge in domestic production and a corresponding collapse in import volumes, fundamentally altering the sector's vulnerability.

Domestic production surge enabled import substitution

EU production of building stone increased dramatically. Production quantity grew from 13.9 billion kg in the first reported period to 86.1 billion kg in the last, a 521% increase. Production value more than doubled, rising 102.5% to €1.28 billion. This massive scaling up of EU output (production volumes) provided a direct substitute for imported stone, particularly for the dominant crude granite segment (CN 251611).

Import volumes and values declined in tandem

The increased domestic capacity directly impacted import flows. The value of EU imports from non-EU countries fell from €323 million in 2015 to €203 million in 2025. The contraction was even starker in volume terms, where import quantities dropped by 35.2%. The EU's trade intensity – the share of total domestic production that is traded – plummeted from 54.1% to 15.8%, underscoring that the market became increasingly oriented towards internal EU circulation.

Import reliance metrics hit record lows

The combination of rising production and falling imports led to a historic reduction in dependency. Net import reliance fell to 9.8% in 2025, meaning the EU was nearly self-sufficient. The trade balance improved by 46.1%, moving from a deficit of €241 million to €130 million. This signifies a strategic shift from a net-importing to a near-balanced market.

2. A Turbulent Decade for Suppliers: Volatility and Shocks

The path to reduced dependency was marked by significant instability for external suppliers. Trade with key partners was highly volatile, and sudden price shocks disrupted established relationships.

Traditional suppliers bore the brunt of declining demand

The EU's largest historical suppliers experienced dramatic declines. Import values from Brazil fell by 64.8%, from India by 35.1%, and from South Africa by 33.6%. This trend reflects both the overall market contraction and a shift in sourcing patterns. The concentration of imports, measured by the Herfindahl-Hirschman Index (HHI), fell from 1378 to 1211, indicating a move towards a less concentrated, though still moderately concentrated, supplier base.

Trade with partners was exceptionally volatile

Coefficient of Variation (CV) data reveals that trade flows with many partners were highly unstable. Imports from Norway and the United Kingdom showed extreme volatility, with CVs of 1.10 and 1.31 respectively. A major price shock for UK imports was detected in 2020, with an abnormality score of 56.3 and a price shift of 578.2%, though its share of total import value was small (1.4%). Similarly, exports to the United States and Gibraltar were highly volatile (CV > 1.8).

Price differentials and segment shifts caused instability

The average import price for the market varied significantly, peaking in 2022. A closer look at segments shows divergent trends. For instance, the average import price for sandstone (CN 251620) spiked to €337 per tonne in 2022, up from €177 in 2015, while prices for other monumental stone (CN 251690) were volatile but ended lower. These price fluctuations, often linked to logistics costs and demand cycles, created a challenging environment for suppliers.

3. The Rise of the EU as an Exporter: Diversification and Specialisation

Paradoxically, as the EU reduced its import needs, it simultaneously developed its export capacity. This was not a return to old patterns but a strategic diversification into new markets and higher-value products, led by a few specialised member states.

Export markets diversified away from traditional partners

EU exports became more geographically diversified. While shipments to China fell by 79.4%, exports to Algeria and Tunisia grew by 687.9% and 624.3% respectively. Exports to the United States also increased by 126.2%. This diversification is reflected in the plummeting HHI for exports, which fell from 2470 to 914, indicating a shift from a highly concentrated to a highly competitive export structure.

A core group of specialised EU producers drove growth

Not all EU members contributed equally. Export growth was concentrated in states with high specialisation. Spain saw its export value increase by 187.8%, and Italy grew by 18.5%. Data on specialisation confirms this: Portugal, Sweden, and Spain have the highest Revealed Symmetric Comparative Advantage (RSCA) scores, indicating they are the most specialised exporters in the EU.

Product mix evolved towards processed and other stone

The composition of EU exports shifted. While crude granite (CN 251611) remained the largest volume segment, its export value slightly decreased. In contrast, exports of "other monumental stone" (CN 251690) saw their value rise by 140.7% and volumes surge from 40,272 tonnes to 294,470 tonnes. This suggests EU exporters may be moving towards higher-value or niche stone products. The export price for merely-cut granite (CN 251612) remained high, averaging above €300 per tonne in the latter years, indicating a focus on more processed goods.

Conclusion

Over the 2015-2025 period, the EU's market for building stone (CN 2516) underwent a transformative rebalancing. Driven by a five-fold increase in domestic production, the EU successfully reduced its net import reliance from 44% to under 10%, achieving near self-sufficiency. This transition was turbulent for external suppliers, who faced collapsing volumes and high volatility. Concurrently, the EU leveraged its enhanced productive capacity to become a more competitive and diversified exporter, targeting new markets in North Africa and North America. The market structure evolved from one of dependency and concentration to one characterized by greater autonomy, export dynamism, and the strategic leadership of specialised EU producers like Spain, Italy, and Portugal. The period thus marks a decisive shift towards a more resilient and globally competitive European building stone sector.
