Market evolution: Carbides (CN 2849) — 2015–2025

Introduction

Carbides (CN 2849) encompass a family of industrially critical inorganic compounds — including silicon carbide (CN 284920), calcium carbide (CN 284910), and specialty carbides such as tungsten, boron, and chromium carbides (CN 284990). These materials underpin sectors ranging from steelmaking and abrasives to semiconductors, cutting tools, and advanced ceramics. The Scope & Definitions page details the product hierarchy under HS Chapter 28.

This report examines the EU's trade in carbides with non-EU countries over the period 2015–2025 at the annual frequency. Despite broadly stable headline trade values, the decade has been marked by pronounced shifts in trade volumes, unit prices, partner concentration, and product composition. Three main dynamics emerge: a striking volume–value divergence that accelerated after 2020; a profound geographic reorientation of import supply toward China; and a structural transformation of EU production and export profiles toward higher-value, specialised carbides. These dynamics carry significant implications for EU industrial resilience.

1. Volume–Value Divergence: Rising Prices Amid Shrinking Flows

EU export values grew 19 % while export volumes fell 21 %

The headline paradox of the decade is visible in the overall trade figures. EU carbide exports rose in value from €73.0 million in 2015 to €86.6 million in 2025 (+18.7 %), yet the tonnage shipped abroad fell from 37,213 tonnes to 29,290 tonnes (−21.3 %). This divergence is entirely explained by a surge in unit export prices, which climbed from €1,962 per tonne to €2,957 per tonne (+50.7 %).

On the import side, the picture is almost the mirror opposite: import values were essentially flat (−0.6 %) while volumes edged up by 4.2 %, implying a mild decline in unit import prices (−4.7 %). The EU's trade deficit in carbides narrowed modestly from €155 million to €140 million, but remains substantial: the EU has consistently been a net importer of carbides throughout the period.

The year 2022 stands out as an extreme price event

A year-by-year decomposition reveals that 2022 was an extraordinary inflection point. Reconstructing from the product segment data, EU export values surged to €118.6 million in 2022 — the maximum of the entire period — even as export volumes had already fallen to 34,460 tonnes from their 2021 peak of 58,112 tonnes. The implied unit export price roughly doubled in a single year, from approximately €1,563/t in 2021 to €3,442/t in 2022. Import values likewise spiked to €376.6 million (the period maximum), with both volumes (+36 % year-on-year) and prices contributing.

This spike aligns with the 2022 European energy crisis, which simultaneously reduced EU domestic carbide production capacity (energy-intensive manufacturing) and inflated input costs. Export prices subsequently moderated but remained well above pre-crisis levels through 2025.

Price shocks were concentrated in specific export markets

The volatility analysis identifies several extreme price shock events. The most significant was an export price shock to the United States in 2021, with an abnormality score of 1,477.8 and a year-on-year price shift of +622.7 %. Given the US market's 23.9 % share of EU carbide export value, this event had an outsized impact on aggregate export unit values. Additional, smaller-magnitude price shocks were detected in exports to Russia (+1,579.7 % in 2022) and Canada (+2,198.5 % in 2022), both likely linked to the geopolitical disruptions following Russia's invasion of Ukraine. While these latter shocks had small value shares (1.2 % and 2.7 % respectively), they illustrate the turbulence that pervaded the global carbide market in 2021–2022.

2. Geographic Rebalancing: China's Ascent and Rising Import Concentration

China's share of EU carbide imports surged from 15 % to 39 %

The most striking geographic shift in the EU's carbide trade is the dramatic growth of China as a supplier. EU imports from China rose from €34.6 million in 2015 to €89.2 million in 2025 — an increase of 157.7 %. At the peak in 2022, Chinese carbide imports reached €155.8 million, accounting for over 40 % of total EU carbide import value in that year.

China's growth was largely driven by silicon carbide (CN 284920), which accounts for over 97 % of EU carbide import volumes. Chinese silicon carbide producers have significantly expanded capacity and benefited from lower energy costs, enabling them to offer competitive pricing to European buyers. Brazil also more than doubled its export value to the EU, emerging as a notable secondary supplier.

Traditional European and African suppliers experienced sharp declines

Against China's rise, several historically significant suppliers contracted dramatically. The most affected were:

• Ukraine (−88.5 %): Imports fell from €9.3 million to €1.1 million, with the steepest decline occurring from 2022 onward — a direct consequence of the Russian invasion and the disruption of Ukrainian industrial capacity.
• South Africa (−73.5 %): Declining from €12.6 million to €3.3 million, reflecting reduced competitiveness and possibly supply-side challenges.
• Venezuela (−70.7 %): Imports collapsed from €8.1 million to €2.4 million, consistent with the broader deterioration of Venezuelan industrial output.
• Norway (−32.6 %): Despite remaining the EU's second-largest carbide supplier, Norway's share halved from 32 % to 22 %, likely due to competition from lower-cost Chinese silicon carbide and rising European energy costs affecting Norwegian smelters.

The volatility analysis confirms that these partner relationships were inherently unstable: South Africa (CV 0.79), Venezuela (0.73), and Taiwan (0.83) exhibited the highest coefficients of variation among import partners, indicating persistently erratic supply patterns.

Import concentration increased markedly, raising supply-chain risk

The Herfindahl–Hirschman Index (HHI) for EU carbide imports rose substantially over the decade:

The import HHI by volume nearly tripled, moving from a moderate-concentration zone into a highly concentrated territory. This is almost entirely attributable to the dominance of Chinese silicon carbide in EU import volumes. While the HHI by value rose more modestly (to 2,193), this still reflects a meaningful consolidation of supply risk.

On the export side, concentration by value actually declined (from 1,274 to 873), indicating that EU exports became more diversified across partner countries — a positive development in terms of market resilience. The export partner data shows that while the United States and United Kingdom remained important destinations, their combined share declined (from 41 % to 20 %), while emerging markets like Türkiye (4.6 % → 7.3 %) and South Africa (0.1 % → 5.4 %) gained ground.

3. Value-Chain Upgrading: EU Production Shifts and Export Specialisation

EU carbide production volumes declined while values rose — a structural upgrade

Domestic EU production data reveals a clear trend toward higher-value output. Production volumes fell from 332,871 tonnes in 2015 to 307,264 tonnes in 2025 (−7.7 %), yet production values rose from €531.7 million to €626.2 million (+17.8 %). The implied unit value of domestic production increased from approximately €1,597/t to €2,038/t — a 28 % rise — pointing to a compositional shift toward higher-margin carbide products.

This pattern is consistent with a broader European industrial strategy of moving away from bulk, energy-intensive carbide production (particularly bulk silicon carbide) and toward specialty and advanced carbides with higher technical specifications and margins.

Specialty carbides increasingly define the EU's export profile

The product segment breakdown reveals a pronounced shift in the composition of EU exports. Specialty carbides (CN 284990 — excluding calcium and silicon carbides) grew from 46.3 % of EU carbide export value in 2015 to 52.0 % in 2025, reaching €45.0 million. Their unit export price surged from €28,935/t to €55,432/t — nearly doubling over the decade.

The contrast with the import profile is instructive. EU carbide imports remain overwhelmingly dominated by silicon carbide (CN 284920), which accounts for 97.7 % of import volumes but only 68.9 % of import value. Specialty carbides (CN 284990) represent just 1.8 % of import tonnage but 30.9 % of import value, at a unit price of €30,325/t. The EU thus imports specialty carbides at roughly half the unit price at which it exports them — consistent with a role as a processor, refiner, or niche-product manufacturer that adds significant value within the carbide value chain.

The EU specialisation analysis confirms this picture. Sweden (RSCA 0.61) and Slovakia (RSCA 0.60) are the most specialised EU carbide exporters, followed by Romania (0.43) and Denmark (0.34). Germany, the largest absolute producer (31 % of EU production volume), has a moderate specialisation score (RSCA 0.18) but dominates in sheer scale.

Export propensity declined sharply, signalling a growing domestic orientation

Despite the value-chain upgrade, the EU's export propensity — the share of domestic production that is exported — fell from 15.1 % to 10.1 % over the decade (−33.3 %). This decline was gradual, reaching a low of 9.5 % in the most recent years before a slight uptick to 10.1 % in 2025.

Source: Net import reliance, Trade intensity, Export propensity

The salience analysis identifies export propensity as the dominant vulnerability indicator (score 73.2 vs. 25.9 for trade intensity). The falling export propensity suggests that EU-produced carbides are increasingly absorbed by the domestic market rather than sold abroad. This may reflect growing intra-EU demand from downstream industries (e.g., electric vehicles, renewable energy, and semiconductor manufacturing) or, conversely, a loss of competitiveness in export markets for bulkier carbide products.

Net import reliance remained broadly stable at around 24 %, meaning that roughly one-quarter of the EU's carbide consumption is met by net imports. This figure masks important compositional shifts: the EU is heavily reliant on imports for bulk silicon carbide but is self-sufficient — or even a net exporter — in specialty carbides.

Conclusion

The EU carbide market between 2015 and 2025 has been shaped by three intertwined dynamics. First, a structural shift in trade volumes and values: the EU now exports fewer tonnes at significantly higher prices, reflecting a move up the value chain into specialty carbides where unit values can exceed €55,000 per tonne. Second, a profound geographic reorientation of imports: China has become the dominant supplier, accounting for nearly 40 % of import value, while traditional partners in Norway, Ukraine, and Africa have declined sharply. This has driven import concentration to historically high levels, increasing the EU's exposure to supply disruptions from a single source. Third, EU domestic production has been reshaped: volumes contracted by 8 %, but values rose by 18 %, and the share of production exported has fallen significantly.

The year 2022 emerges as the pivotal moment of the decade — when the energy crisis, post-pandemic demand, and geopolitical disruption combined to produce extraordinary price spikes across both imports and exports. While prices have since moderated, they have not returned to pre-crisis levels.

Looking ahead, the data points to a market that is more specialised but also more exposed. The EU's growing reliance on Chinese silicon carbide, combined with reduced export orientation and persistently elevated trade concentration, suggests that strategic attention to supply-chain diversification and domestic capacity in both bulk and specialty carbides will be important for maintaining industrial resilience.
