Market evolution: Carbon copying paper (CN 4816) — 2015–2025

Introduction

This report analyses the evolution of EU trade in products classified under Combined Nomenclature code 4816, which encompasses carbon paper, self-copy paper, and other copying or transfer papers (including duplicator stencils and offset plates of paper). The period under review—2015 to 2025—has witnessed significant structural shifts in this niche segment of the paper industry. While the EU has historically maintained a positive trade balance in this product category, the data reveals a pronounced contraction in export volumes, a geographic reorientation of both import and export flows, and a market increasingly shaped by the broader decline in analogue copying technologies. This report examines these dynamics through three lenses: the macro trade trajectory, the geographic restructuring of partnerships, and the underlying structural and price transformations that define the market today.

1. The EU's Shrinking Trade Surplus: A Decade of Declining Export Dominance

The overall trade balance has narrowed significantly despite sustained EU production

The EU entered the period with a robust trade surplus of approximately €31.0 million in 2015, driven by exports valued at €39.9 million against imports of €8.9 million (General Overview). By 2025, this surplus had contracted to €17.7 million—a decline of 43.1%. This narrowing reflects a fundamental divergence: export revenues fell by 23.9% while import values rose by 43.3% over the same period.

The contraction is even more dramatic in volumetric terms. Export quantities plummeted by 47.6%, from 28,109 tonnes to 14,715 tonnes, while import volumes grew by 48.1%, from 2,469 tonnes to 3,656 tonnes. This divergence is summarized in the following table:

Export volumes have declined far faster than export values, signalling a shift toward higher-value products

A striking feature of the period is the decoupling of export value and volume. While export quantities nearly halved, the decline in export revenues was limited to about 24%. The explanation lies in the 45.4% increase in average export unit prices, from €1,419/tonne to €2,063/tonne. This pattern is consistent with a market in which lower-value, high-volume copying papers have been progressively replaced by digital alternatives, while remaining exports increasingly consist of specialised or niche products commanding higher prices.

The Product Segment Breakdown confirms this interpretation. Self-copy paper (CN 481620) has remained the dominant export sub-product, accounting for the vast majority of export volumes (13,897 tonnes out of 14,715 tonnes in 2025). However, the "other copying or transfer papers" sub-category (CN 481690), though much smaller in volume, exhibits far higher unit prices—reaching €11,648/tonne in 2022 compared to €2,131/tonne for self-copy paper in the same year. This indicates that the residual EU export basket contains a significant share of higher-value transfer papers and offset plates.

EU production has expanded substantially even as export trade has contracted

One of the more counterintuitive findings is that EU domestic production of CN 4816 products has grown dramatically over the period. Reported production volumes increased from 16.1 million kg in the first period to 50.0 million kg in the last—a rise of 209.7%. Production values followed a similar trajectory, growing by 218.1% from €32.1 million to €102.0 million.

This suggests that while external trade in CN 4816 has declined, the EU's internal market and production base have expanded—potentially reflecting growing intra-EU demand for self-copy papers used in logistics, healthcare, and administrative applications that remain paper-dependent, or alternatively reflecting the concentration of remaining global production capacity within the EU.

2. Geographic Reorientation: The Rise of Asian Imports and the Consolidation of Export Partners

Asian suppliers have displaced the United States as the primary source of EU imports

The geographic composition of EU imports has undergone a dramatic transformation. In 2015, the United States was by far the largest supplier, accounting for €4.5 million in imports—more than half the total (Top partners by value). By 2025, US imports had declined to €3.1 million (−32.6%), while China's share surged from €0.5 million to €4.7 million—an extraordinary increase of 796.6%. Thailand's growth was even more spectacular in relative terms, rising from just €6,234 to €1.1 million (+17,832.5%), while Indonesia and Türkiye also registered significant gains.

This shift reflects the broader global migration of paper and chemical-intensive manufacturing to East and Southeast Asia. China and Thailand, in particular, have emerged as competitive producers of self-copy paper, benefiting from lower production costs and integrated pulp supply chains. The concentration analysis confirms that the import Herfindahl-Hirschman Index (HHI) declined from 3,152 to 2,229 (−29.3%), indicating a diversification of import sources away from US dependency.

EU exports have become more concentrated, with the United States emerging as the dominant destination

In contrast to the diversification of import sources, EU exports have become markedly more concentrated. The export HHI rose from 1,458 to 2,110 (+44.7%), driven primarily by the growing importance of the United States as an export destination. US-bound exports nearly doubled from €6.3 million to €12.3 million (+97.3%), making the US by far the largest single market for EU carbon paper exports in 2025.

The collapse of the Turkish export market (−89.6%) is particularly notable. From being the second-largest destination at €6.5 million in 2015, Türkiye became a marginal market by 2025. This likely reflects Turkey's own development of domestic production capacity and possibly trade policy shifts. The halving of UK-bound exports (−50.9%) coincides with Brexit, as the UK's departure from the EU customs union introduced new trade frictions, even though the UK remained the second-largest destination at €5.8 million.

The EU's net import reliance has shifted but remains manageable

The net import reliance metric moved from −30.8% in 2015 to −10.2% in 2025, a positive change of 67.0%. Negative values indicate that the EU remains a net exporter—its exports exceed its imports—but the margin has narrowed considerably. The metric reached extreme values in certain years (as low as −275.9%), reflecting high volatility in the trade flows of this relatively small market segment. Nevertheless, the trend is clear: the EU is becoming less of a net exporter and more self-sufficient in relative terms, as rising import volumes partially offset declining exports.

3. Price Dynamics, Supply Shocks, and the Structural Transformation of a Declining Product Category

Import and export prices have diverged, reflecting different product mixes and market segments

A key structural feature of the CN 4816 market is the persistent gap between import and export unit prices. EU import prices have consistently exceeded export prices by a significant margin—€3,474/tonne versus €2,063/tonne in 2025. This 68% premium reflects the different composition of traded goods: imports likely consist of more specialised or higher-value transfer papers (CN 481690), while exports are dominated by higher-volume, lower-unit-value self-copy paper (CN 481620).

The product segment breakdown confirms this pattern. Within imports, CN 481690 (other copying/transfer papers) commanded unit prices ranging from €2,177/tonne to €5,287/tonne over the period, while CN 481620 (self-copy paper) ranged from €2,003/tonne to €2,952/tonne. Within exports, the price differential was even more pronounced: CN 481690 exports reached €11,648/tonne in 2022, compared to €2,131/tonne for CN 481620, suggesting that the EU specialises in exporting niche, high-value transfer papers while importing commodity-grade self-copy paper.

Significant price shocks have disrupted trade flows in 2022–2023

The volatility and shock analysis identifies several notable supply shocks concentrated in 2022 and 2023. The most significant events include:

The Russian export price shock in 2023—with a 342.6% price increase—is almost certainly linked to the geopolitical disruption following Russia's invasion of Ukraine and the subsequent EU sanctions regime. While Russia represented only 2.3% of export value, the magnitude of the price distortion is remarkable and likely reflects the re-routing of trade flows and the imposition of sanctions-related restrictions.

The Turkish and UK export price shocks in 2022 (with abnormality scores of 19.0 and 17.9 respectively) coincided with the global surge in energy and raw material costs that followed the post-COVID recovery and the onset of the energy crisis. Given that the UK alone accounted for 35.5% of EU export value, this price shock had substantial macroeconomic significance for the EU carbon paper sector.

Trade intensity has collapsed, confirming the secular decline of this product category

Perhaps the most telling indicator of the structural transformation underway is the trade intensity metric, which fell from 151.0% to 33.0% (−78.1%). Similarly, export propensity collapsed from 185.0% to 23.5% (−87.3%). These dramatic declines indicate that the EU's CN 4816 market has become far less trade-oriented over the decade.

In 2015, trade intensity above 100% signified that the EU was a major net exporter with trade volumes exceeding the size of the domestic market. By 2025, the market has become predominantly domestic, with trade flows shrinking relative to production. This is consistent with the observed tripling of domestic production volumes: as the EU's internal market has absorbed more output, the relative importance of external trade has diminished.

The specialisation analysis further confirms this picture. Among EU member states, Germany dominates with 53.0% of EU production value and a Revealed Comparative Advantage (RCA) of 2.50, indicating significant specialisation. Croatia shows the highest RCA (9.86), though on a much smaller production base. At the other extreme, Ireland, Bulgaria, and Austria show negligible specialisation, consistent with their minimal domestic production.

Conclusion

The EU trade market for CN 4816 products has undergone a profound structural transformation between 2015 and 2025. Three overarching dynamics define this evolution:

1. The secular decline of analogue copying technologies has reduced global demand for carbon paper and self-copy paper, leading to a near-halving of EU export volumes even as domestic production has tripled. The market is consolidating around fewer, higher-value products and fewer, more concentrated trade relationships.

2. A geographic reorientation of supply chains has seen Asian producers—particularly China and Thailand—displace the United States as the primary source of EU imports. On the export side, the United States has become the dominant destination, absorbing nearly €12.3 million in 2025, while traditional markets like Türkiye and the United Kingdom have contracted sharply.

3. The EU has become increasingly self-sufficient in this product category, with trade intensity and export propensity both collapsing to a fraction of their 2015 levels. Rising domestic production has reduced the EU's reliance on external trade, even as the trade surplus has narrowed under the pressure of growing imports.

Looking ahead, the continued digitalisation of administrative and commercial processes suggests that the CN 4816 market will continue to contract in absolute terms. However, the EU's strong production base—led by Germany—and its specialisation in higher-value transfer papers position it to retain a residual competitive advantage in the niche applications where carbon and self-copy paper remain irreplaceable.
