Market evolution: Other inorganic salts (CN 2842) — 2015–2025

Introduction

This report examines the evolution of EU trade in CN 2842 — a residual customs heading covering salts of inorganic acids or peroxoacids, including aluminosilicates, whether or not chemically defined. The heading is composed of two sub-headings: 284210 (double or complex silicates, including aluminosilicates) and 284290 (all other salts of inorganic acids or peroxoacids not elsewhere specified). Because it bundles many distinct chemical products, CN 2842 serves as an indicator of broad trends across multiple segments of the European inorganic chemicals industry rather than a single well-defined market.

Over the 2015–2025 period, the EU's trade in this product category underwent a striking transformation. The bloc shifted from a net trade deficit of €72.3 million in 2015 to a net surplus of €110.1 million in 2025 — a swing of over €182 million. However, this headline improvement was driven overwhelmingly by soaring unit prices rather than by growing trade volumes: export quantities nearly halved while import volumes barely changed. Meanwhile, EU domestic production volumes collapsed by 86%, even as production values nearly doubled, pointing to a deep structural transformation in how and where these products are made. Three dynamics stand out: the EU's transition into a net exporter through price-led value gains, a dramatic reorientation of trade geography with China and the United States, and a significant restructuring of domestic production toward higher-value output at sharply reduced scale.

1. From Deficit to Surplus: A Price-Led Export Revolution

The headline swing in the trade balance

In 2015, the EU ran a trade deficit of €72.3 million on CN 2842 products with non-EU countries, importing €196.9 million versus exporting €124.7 million. By 2025, the picture had reversed entirely: exports reached €352.6 million against imports of €242.6 million, yielding a surplus of €110.1 million. The balance turned positive around 2021 and peaked in 2023 before moderating. On the import side, the increase was more modest: a gain of 23.2% in value over the decade.

Volume decline masked by extraordinary price growth

The most striking feature of this period is the decoupling of values from volumes. EU export volumes fell by 48.1% — from 120,913 tonnes in 2015 to just 62,740 tonnes in 2025 — yet export values rose by 182.9%. This was possible only because average export prices surged by 445%, climbing from €1,031 per tonne to €5,617 per tonne.

Import prices grew too, but far more moderately (+30.6%). The asymmetry is important: the EU's surplus was not won by exporting more goods, but by commanding dramatically higher prices for what it did export.

Sub-segment divergence: 284290 drives the price revolution

The two sub-headings evolved very differently. In exports, 284290 (other inorganic salts, n.e.s.) saw its volume collapse by 76.9% (from 54,214 tonnes to 12,541 tonnes) while its price per tonne exploded by 1,277% (from €776 to €10,678). Its export value nonetheless grew by 218.7% to €134.2 million. By contrast, 284210 (complex silicates including aluminosilicates) saw its export price increase by a more moderate 252% (from €1,237 to €4,352/tonne), while its value rose from €82.5 million to €218.5 million.

On the import side, the two segments diverged even more clearly. Silicate imports (284210) saw volumes decline by 24.1% (from 52,804t to 40,049t) with value remaining roughly flat at €181 million. Meanwhile, 284290 imports grew in both volume and value: quantities rose from 6,315 tonnes to 15,717 tonnes (+148.9%) and value nearly tripled from €22.4 million to €61.6 million (+174.8%). This suggests growing EU demand for specialised inorganic salts that are increasingly sourced from outside the bloc.

EU production: volume collapse, value doubling

EU domestic production data paints a dramatic picture. Production volumes fell from 1,159,098 tonnes to 160,000 tonnes — a collapse of 86.2% — while production values nearly doubled from €244 million to €480 million (+96.7%). This implies average domestic production prices rose more than thirteen-fold. Taken together, the data suggests a fundamental restructuring of the European industry: lower-value, high-volume production has been progressively offshored or discontinued, while remaining EU output has moved toward higher-value, more specialised products. This is consistent with the EU's broader pattern of de-industrialisation in basic chemicals, where energy costs and environmental regulation have eroded the competitiveness of volume-oriented manufacturing.

2. Reorientation of Trade Partners: China and the United States Reshape the Map

China's meteoric rise as an import supplier

The most dramatic shift on the import side was the emergence of China as the EU's dominant supplier. Chinese exports to the EU grew by 503%, from €16.7 million in 2015 to €100.6 million in 2025 — making China by far the largest single source of these products, accounting for roughly 41% of EU imports by value. At its peak in 2023, Chinese imports reached €129.4 million.

This growth came at the expense of other suppliers. The United States, which was the EU's top import partner in 2015 at €85.7 million, saw its share decline by 45.2% to €46.9 million. Japan remained broadly stable (−1.7%), while Switzerland collapsed from €2.5 million to under €0.5 million (−80.6%). Bosnia and Herzegovina maintained a presence but at much lower absolute values.

The US as the EU's export engine

On the export side, the United States became the overwhelmingly dominant market. EU exports to the US surged by 405.9%, from €35.0 million to €177.2 million — representing fully half of all EU extra-EU exports by 2025. Other notable growth markets included China (+302.4%, reaching €25.5 million), Türkiye (+214.4%, reaching €8.0 million), and the United Kingdom (+52.5%, reaching €11.2 million).

A particularly volatile story involved North Macedonia, which went from a negligible €15,560 in 2015 to a peak of €104.9 million in one year before settling at €19.6 million in 2025. This suggests episodic, large-scale shipments likely linked to specific industrial projects or re-export activity rather than a stable trade relationship.

Growing export concentration, modestly declining import concentration

The Herfindahl-Hirschman Index (HHI) confirms these geographic shifts. Import concentration by value decreased only slightly, from 2,995 to 2,751 (−8.1%), remaining in the moderately concentrated range. But export concentration more than doubled, from 1,205 to 2,730 (+126.5%). A score below 1,500 is typically considered unconcentrated; the EU's exports have now crossed into the moderately concentrated zone, primarily because of the growing dominance of the US market. This creates a vulnerability: any disruption to US-bound trade — whether through tariffs, regulatory changes, or demand shifts — would have outsized effects on EU exporters.

Price volatility across trading partners

The volatility analysis reveals substantial instability in certain bilateral trade flows. On the export side, Kuwait (coefficient of variation 2.59), North Macedonia (1.58), and Switzerland (0.83) show the most erratic behaviour. On the import side, the Philippines (0.88), Switzerland (0.76), and the United Kingdom (0.67) were the most volatile suppliers.

Several price shock events were detected. The most significant involved EU exports to Egypt in 2022, where the unit price spiked by 427.6% with an abnormality score of 605.4, and to North Macedonia in 2018, where prices surged by 2,943.7%. These isolated spikes likely reflect one-off high-value shipments or reclassifications rather than sustained market shifts, but they illustrate the inherent volatility in a product category this heterogeneous.

3. Production Restructuring and EU Specialisation Patterns

Concentrated specialisation: the Netherlands and Germany dominate

The specialisation analysis for 2025 reveals a highly uneven distribution of CN 2842 activity across EU member states. The Netherlands and Slovenia stand out as the most specialised producers/exporters, with revealed symmetric comparative advantage (RSCA) scores of 0.52 and 0.48 respectively — well above the threshold indicating strong specialisation. The Netherlands alone accounts for 45.9% of EU production in this category despite representing just 14.5% of total EU trade in inorganic chemicals.

Germany occupies a distinctive position: while its RSCA is only modestly positive (0.066), it is the second-largest producer (24.2% of production) and, importantly, the EU's largest exporter to non-EU countries at €225.1 million in 2025 — a gain of 217.2% from €71.0 million in 2015. Germany's role appears to be that of a processing and re-export hub, importing raw or intermediate inorganic salts and exporting higher-value finished or semi-finished products.

At the other end, several member states — including Romania, Estonia, Hungary, Bulgaria, and Austria — show near-zero specialisation (RSCA close to −1.0), with negligible production shares and no meaningful comparative advantage in this category.

The EU's internal importers: the Netherlands and Poland

Looking at which EU countries absorb the most extra-EU imports, the Netherlands led with €68.8 million in 2025, followed by Poland (€50.3 million, up 105.8%), Germany (€29.1 million, down 26.5%), and France (€31.0 million, roughly flat). The notable growth in Polish imports likely reflects the country's expanding chemical processing sector, while the Netherlands' role as both the top producer and top importer underscores its function as the EU's central hub for inorganic chemicals logistics and trade.

Shifting EU export leadership

Among EU exporters, Germany's dominance grew substantially, accounting for €225.1 million of the EU's €352.6 million total in 2025 (63.9%). The Netherlands came second at €46.1 million, while Italy showed the fastest growth — a remarkable 480.5% increase to €24.1 million, suggesting that Italian producers found profitable niches in the post-2015 price environment. Poland also emerged as a significant exporter, growing 758% to €9.9 million.

Trade intensity and the EU's deepening openness

The trade intensity and export propensity metrics confirm the structural shift. Trade intensity — the ratio of total trade to apparent EU consumption — rose from 50.8% to 83.0% (+63.4%), indicating that the EU market has become far more integrated with global trade flows. Even more strikingly, export propensity surged from 37.6% to 73.4% (+95.3%), meaning the EU now exports nearly three-quarters of its CN 2842 output, up from barely one-third a decade ago.

The net import reliance metric — which is negative when the EU is a net exporter — moved from −12.0% to −20.3%, confirming that the EU's position as a net exporter strengthened over the period, even though it briefly reached an even more pronounced −35.4% in 2023. The 2023 peak and subsequent retreat suggest that the extreme price-driven surplus of that year was partially corrected, but the underlying trend toward net-exporter status is clear.

Conclusion

The EU's trade in CN 2842 products over 2015–2025 tells a story of paradoxical transformation. By value, the EU strengthened its position dramatically — swinging from a €72 million deficit to a €110 million surplus and more than tripling its export revenues. Yet this headline success masks a more fragile reality: export volumes nearly halved, domestic production collapsed by over 86%, and the export market has become dangerously concentrated on the United States, which absorbs more than half of all EU exports by value.

The price dynamics — with export unit values rising 445% versus a 31% increase in import prices — suggest that the EU has shifted from competing on volume to competing on value, likely by exiting lower-margin bulk production and focusing on higher-specification products. China's rise as the dominant import supplier (from €16.7 million to €100.6 million) fills the volume gap that EU producers have vacated. The structural result is an EU that is simultaneously more dependent on Chinese imports for quantity and more dependent on the US market for export revenue — a dual dependency that creates distinct but complementary risks.

Going forward, policymakers and industry stakeholders should watch two indicators closely: the concentration of EU exports in the US market (where the HHI has already doubled), and the trajectory of Chinese import penetration. Any significant disruption to either axis — whether through trade policy, geopolitical tensions, or demand shifts — would reverberate rapidly through a market that has become both more open and more specialised over the past decade.
