Market evolution: Phosphoric acid and polyphosphoric acids (CN 280920) — 2015–2025

Introduction

This report examines the evolution of EU external trade in phosphoric acid and polyphosphoric acids (Combined Nomenclature code 280920) over the period 2015–2025. Phosphoric acid is a critical industrial chemical used primarily in fertiliser production, food processing, and metal treatment. The EU's position in this market has undergone substantial structural change over the past decade. Drawing on trade data covering imports, exports, production, partner concentration, and vulnerability indicators, three major dynamics emerge: a dramatic contraction of EU domestic production accompanied by rising import dependence; a severe price shock centred on 2022 that reshaped trade values; and a significant geographic realignment of both import and export partners. Each of these dynamics is examined in the sections that follow.

1. The erosion of EU domestic production and deepening import dependence

The most striking structural feature of the EU phosphoric acid market over 2015–2025 is the simultaneous collapse of domestic production and the growing reliance on imports. While the EU's trade deficit in value terms remained deeply negative throughout the period, the underlying composition of that deficit shifted fundamentally.

EU production volumes fell by nearly two-thirds

Available production data, measured in kilograms of phosphorus pentoxide (P₂O₅), reveals a dramatic contraction:

Production volume fell by 64.3%, yet production value declined by only 5.2%. This divergence implies that the unit value of EU-produced phosphoric acid roughly tripled over the decade, suggesting that what remains of EU production is concentrated in higher-value, more specialised grades while commodity-grade output has been offshored or discontinued.

Net import reliance nearly doubled

The net import reliance indicator captures how much of the EU's apparent consumption is met by net imports:

Net import reliance rose from 41.1% to 67.4%, meaning that by 2025 roughly two-thirds of the EU's phosphoric acid consumption was supplied by net imports. Trade intensity — the ratio of total trade (imports + exports) to the size of the domestic market — surged from 47.9% to 83.3%, confirming that the EU economy became vastly more exposed to international trade flows in this product.

The most dramatic change, however, is in export propensity, which rose from 7.6% to 41.7% — a 448% increase and the most salient metric according to the vulnerability assessment. This counterintuitive rise in exports alongside declining production likely reflects a combination of re-export and processing activities (importing raw acid, processing it into higher-purity or higher-value products, then exporting), as well as the impact of higher unit prices on the measured value of exports. Belgium, the EU's most specialised exporter with a Revealed Symmetric Comparative Advantage (RSCA) of 0.63 and an RCA of 4.46, is simultaneously a major importer — consistent with a hub-and-re-export model centred on the Port of Antwerp.

The trade deficit persisted despite falling import volumes

Import volumes declined by 20.3% while import values rose by 14.3%, driven entirely by higher unit prices. Export volumes fell less steeply (−10.2%) but export values grew by 42.3%, again propelled by prices. The resulting trade deficit widened modestly in nominal terms to €703 million. Notably, the EU's export unit price (€1,113/t) substantially exceeded its import unit price (€727/t) by 2025, suggesting that the EU was exporting higher-grade or more processed material.

2. The 2022 price shock and its structural consequences for EU trade

While prices trended upward over the full 2015–2025 period, the year 2022 stands out as an acute shock that disrupted both import and export pricing. The shock detection analysis identifies three major events centred on 2022, and the broader volatility data reveals lasting instability in several trade relationships.

Three major price shocks were detected in 2022

The shock detection analysis identifies the following abnormal price events:

The most economically significant shock was the EU–US export price surge: the United States accounted for 68.7% of EU export value, and prices to that market more than doubled in a single year. The Israel import price shock — with Israel representing 38.8% of EU import value — similarly rippled through the EU's input costs. Norway's export shock, while dramatic in relative terms (+113.5% shift, with an abnormality score of 73.9 indicating extreme deviation from the norm), was smaller in absolute value terms.

These 2022 shocks are broadly consistent with the global commodity price surge triggered by the Russia–Ukraine conflict, energy cost escalation, and supply-chain disruptions that characterised that year.

Import and export unit prices peaked sharply in 2022

Examining the trajectory of unit prices reveals the 2022 spike clearly:

*Estimates derived from min/max bounds and overall trends.

Import prices reached a peak of €1,034/t and export prices hit €1,414/t, both roughly double their pre-shock levels. By 2025, prices had partially corrected but remained 43.5% and 58.4% above their 2015 starting points, respectively — suggesting that the 2022 shock was not entirely transitory.

Certain trade relationships exhibit persistently high volatility

The coefficient of variation (CV) across the full period highlights which bilateral flows are most unstable:

Most volatile import sources:

Most volatile export destinations:

Russia and Turkey stand out on the import side with CVs above 2.0, indicating extreme year-to-year instability — likely reflecting geopolitical disruptions, sanctions effects, and shifting trade routes. On the export side, flows to Canada, South Africa, and Brazil are the most erratic. In contrast, Morocco (CV 0.14) and Israel (CV 0.18) on the import side, and the United Kingdom (CV 0.17) and Switzerland (CV 0.19) on the export side, represent relatively stable, predictable trade relationships.

3. A reshuffling of trade partners: North African dominance, Balkan emergence, and shifting EU export geography

Beyond aggregate volumes and prices, the geographic composition of EU phosphoric acid trade shifted substantially. The import side saw consolidation around Morocco and the emergence of new suppliers, while the export side experienced a dramatic reorientation of intra-EU leadership.

Morocco remained the dominant import source; Serbia emerged as a fast-growing newcomer

The top import partners by value show a clear hierarchy:

Morocco's position as the EU's primary phosphoric acid supplier — reflecting its vast phosphate rock reserves and OCP Group's integrated production — was essentially unchanged in value terms over the decade, accounting for roughly half of all EU imports. Israel, the second-largest source, grew more meaningfully (+12.2%).

The most dramatic development is Serbia's emergence as a significant supplier, rising from virtually zero (€70,435) in 2015 to €43.6 million in 2025. This likely reflects the ramp-up of production facilities leveraging Serbia's proximity to EU markets and its candidate-country trade preferences. South Africa also grew rapidly (+237.2%), while China — despite a peak import value of €175 million at some point during the period — ended the period at just €18.1 million, indicating a substantial retreat from the EU market.

EU export geography shifted, with the US consolidating its lead

The top export destinations also evolved:

The United States consolidated its position as the EU's largest export market, growing by 73.7% to €62.9 million — accounting for over half of total EU export value. The United Kingdom and Switzerland also grew, while exports to Norway, Turkey, Brazil, and South Africa all declined significantly.

Intra-EU leadership in exports shifted from Belgium to the Netherlands

The EU Member State reporter data reveals a major redistribution of export activity within the EU:

Belgium remained a major exporter but saw its share decline, while the Netherlands surged from under €1 million to over €51 million — a 5,624% increase — becoming the EU's largest exporter by 2025. Finland's export activity collapsed by 94.2%, and France also contracted sharply. On the import side, Italy grew from €10.3 million to €70.0 million (+581%), and Ireland from €6.3 million to €22.9 million (+264%), while the Netherlands and Belgium remained the top EU entry points.

Import concentration decreased while export concentration increased

The Herfindahl-Hirschman Index (HHI) of partner concentration tells a nuanced story:

Import concentration declined as new suppliers (Serbia, South Africa) diversified the EU's sourcing away from Morocco and Israel. Export concentration, however, increased — both in value (+32.8%) and volume (+53.8%) — reflecting the growing dominance of the US as an export destination and the consolidation of EU export activity in fewer Member States (principally the Netherlands and Belgium). This divergence carries different risk implications: reduced import concentration lowers supplier-side vulnerability, while increased export concentration raises destination-side risk.

Conclusion

Over the decade 2015–2025, the EU's phosphoric acid market underwent a triple transformation. First, domestic production collapsed by 64% in volume terms, driving net import reliance from 41% to 67% and fundamentally reshaping the EU's position from a partially self-sufficient producer to a heavily import-dependent consumer. Second, the 2022 global commodity shock — reflected in price spikes exceeding 100% in key bilateral flows — left a lasting imprint on trade values, with unit prices in 2025 remaining 44–58% above 2015 levels despite partial correction. Third, the geographic landscape of trade shifted: Morocco's dominance on the import side was supplemented by the rapid emergence of Serbia and South Africa as new suppliers, while the US consolidated its position as the EU's primary export market and the Netherlands displaced Belgium as the EU's leading exporter.

These dynamics point to an EU market that is more price-exposed, more trade-dependent, and more concentrated on the export side than it was at the start of the period. The decline in import concentration provides some resilience against single-supplier risk, but the simultaneous increase in export concentration and overall trade intensity suggests that the EU's phosphoric acid supply chain remains structurally vulnerable to external shocks — whether geopolitical, energy-related, or market-driven. The continued growth of export propensity alongside shrinking production raises important questions about the EU's evolving role in global phosphoric acid value chains, potentially as a high-value processor and re-exporter rather than a primary producer.
