Market evolution: Nucleic acids (CN 2934) — 2015–2025

Introduction

This report analyzes the evolution of the European Union's trade in products under Combined Nomenclature code 2934, which covers nucleic acids, their salts, and a broad category of heterocyclic compounds (excluding those with only oxygen or nitrogen hetero-atoms). The period under review spans from 2015 to 2025. The analysis reveals a market characterized by robust value growth in both exports and imports, a significant shift in import sourcing towards China, rising price levels, and notable volatility linked to major global events. The EU has maintained a positive overall trade balance, but the dynamics of that balance have changed considerably.

Robust Value Growth Driven by Price Increases

Over the 2015–2025 period, the EU's trade in CN 2934 products expanded substantially in monetary terms, with growth in value outpacing growth in physical quantity.

Export and Import Value Outpaces Volume Growth

EU exports of these chemicals increased from €4.20 billion in 2015 to €7.20 billion in 2025, representing a growth of 71.4%. In contrast, export volumes grew by a more modest 24.8%, from 58,017 tonnes to 72,384 tonnes. This indicates that the rise in export value was primarily driven by a 37.4% increase in average export prices over the period. Similarly, imports grew from €3.69 billion to €6.60 billion (+78.9%), while import volumes rose by only 16.8% (from 45,288 to 52,908 tonnes), underscoring a 53.1% increase in import prices.

The EU's Trade Balance Remains Positive but Volatile

Despite strong import growth, the EU maintained a trade surplus in this sector throughout the period. The surplus stood at €510 million in 2015 and ended at €600 million in 2025. However, the balance was highly volatile, peaking at €6.26 billion in 2022 and hitting a low of -€564 million in 2020. The peak in 2022 coincides with the highest recorded value of EU exports (€11.63 billion), suggesting a year of exceptional demand or pricing power for EU producers.

The Ascendancy of China and Price Volatility in Key Relationships

A fundamental structural shift occurred in the EU's import sourcing, with China emerging as the dominant supplier. Concurrently, trade relationships exhibited significant price volatility and were impacted by identifiable economic shocks.

China's Dominant Role in EU Imports

China's position as an import partner strengthened dramatically. EU imports from China surged from €423 million in 2015 to €1.79 billion in 2025, a staggering 322.4% increase. This growth was both volume- and value-driven. In 2025, China accounted for the largest share of EU imports by value among the top partners. Switzerland and the United States remained significant but with much lower growth rates (32.5% and 19.9%, respectively). The top import partners by value data highlights this concentration.

Measured Volatility and Detected Price Shocks

Trade relationships display varying degrees of price volatility. For EU imports, flows with Switzerland (CV=0.34) and the United Kingdom (CV=0.32) were among the most volatile, while those with the United States (CV=0.10) and China (CV=0.13) were relatively more stable. Export volatility was generally higher, with Russia (CV=0.55) and Canada (CV=0.79) showing significant swings. The data identifies specific shock events, most notably a massive 77.1% price shift in imports from the United States centered on 2020, and a 120.0% price shift in exports to India in 2022.

EU Specialisation and Internal Production Trends

Within the EU, the production and export of CN 2934 products are highly concentrated in a few member states, reflecting significant specialization. Meanwhile, EU-level production volumes have trended downward.

High Specialisation in Ireland, Portugal, and Spain

Using the Revealed Symmetric Comparative Advantage (RSCA) index for 2025, Ireland stands out with a very high degree of specialisation (RSCA: 0.84), indicating it is the EU's most competitive exporter in this sector. Portugal and Spain also show strong specialization (RSCA: 0.64 and 0.49, respectively). This specialization is reflected in trade flows: Ireland was by far the largest EU exporter by value in 2025 (€4.33 billion), followed by Germany (€889 million).

Declining EU Production Volumes

Despite strong export performance, EU production of these chemicals has declined. Data indicates that production quantity fell from 108.1 million kg in 2015 to 89.4 million kg in 2025, a decrease of 17.3%. Production value followed a similar downward trend (-17.8%). This suggests that while the EU remains a major global exporter, its share of global production may be decreasing, or its exports are increasingly comprised of re-exports or more specialized, higher-value products not fully captured by the reported production figures.

Conclusion

The EU's market for CN 2934 chemicals from 2015 to 2025 has been defined by strong value growth fueled by rising prices. A major structural change has been the significant increase in imports from China, making the EU increasingly reliant on this single source for a growing share of its supply. Trade balances, while generally positive, have been volatile, and key bilateral relationships have been subject to pronounced price shocks, as seen in the data for the US and India. Internally, production within the EU has decreased, while exports have been sustained by highly specialized and competitive member states like Ireland. The period thus reflects a dynamic market influenced by global supply chain shifts, price pressures, and the strong competitive positioning of specific EU economies.
