Market evolution: Hat forms of felt (CN 6501) — 2015–2025

Introduction

CN 6501 covers hat-forms, hat bodies, hoods, plateaux, and manchons of felt — semi-finished felt components used upstream in the headwear supply chain. Over the 2015–2025 period, the European Union's external trade in this niche product has undergone a remarkable transformation. EU exports grew more than fivefold in value terms while imports contracted by over 40%, producing a swing in the trade balance from €3.5 million to €44.2 million. This report examines the main dynamics behind that shift, the geographic concentration of flows, and the structural implications for EU competitiveness and vulnerability.

General overview on the Trade Dashboard

1. A fivefold surge in exports redefines the EU's trade position

The export boom overshadowed a simultaneous import contraction

The headline story of CN 6501 is the extraordinary divergence between EU exports and imports. Between 2015 and 2025, exports rose from €9.6 million to €47.8 million (+400.3%), while imports fell from €6.1 million to €3.6 million (−40.8%). The resulting trade surplus expanded from €3.5 million to €44.2 million — a staggering increase of over 1,176%.

Volume growth lagged behind value growth, signalling a premium positioning

Export volumes (in tonnes) rose 154.8% (from 87 t to 221 t), while export values grew 400%. This gap is explained by a near-doubling of the unit export price, which climbed from approximately €109,846/t to €215,978/t (+96.6%). In supplementary-unit terms (individual pieces), the price per item rose from €19.4 to €53.6 (+176.4%). These figures suggest that the EU is increasingly exporting higher-value felt hat-forms, likely reflecting a move upmarket or a shift in product mix toward more elaborate or premium components.

On the import side, volumes fell even more sharply than values (−59.8% in tonnes), while the unit import price rose 47.0% — indicating that remaining imports are increasingly priced at a premium, consistent with a contraction at the lower end of the market.

The EU transitioned from a balanced trader to a net supplier to the world

The net import reliance metric remained deeply negative throughout the period (from −712% to −631%), confirming that the EU has been a consistent and substantial net exporter. A negative net import reliance of this magnitude means that exports vastly exceed imports — the EU produces far more than it consumes domestically for this product category.

2. Portugal and the United States: a transatlantic felt supply chain takes shape

The United States became the overwhelmingly dominant export destination

The most striking geographic dynamic is the concentration of EU exports toward the United States. In 2015, the US already absorbed €5.1 million (53% of total extra-EU exports). By 2025, that figure had surged to €41.0 million — representing approximately 86% of all extra-EU exports of CN 6501 and a growth of 707%. No other destination comes close.

Ecuador and Israel also emerged as fast-growing markets, while exports to Australia and the United Kingdom contracted — possibly reflecting post-Brexit trade frictions in the latter case.

Portugal emerged as the EU's undisputed production hub

Within the EU, Portugal dominates CN 6501 exports by a wide margin. Its extra-EU exports grew from €8.3 million in 2015 to €36.4 million in 2025 (+339%), making it responsible for roughly 76% of all EU exports. Portugal's revealed comparative advantage (RCA) stands at 49.5 — an extraordinarily high figure indicating massive specialisation in this product relative to its overall export profile.

Belgium and Czechia entered the market explosively from a near-zero base

While Portugal's dominance grew in absolute terms, Belgium (from €8K to €5.4M) and Czechia (from €1.4K to €2.7M) experienced dramatic percentage growth from negligible starting points. These may reflect the establishment of new production or trading capacities, or the re-routing of felt hat-form supplies through EU logistics hubs.

Export concentration intensified sharply

The Herfindahl-Hirschman Index (HHI) for exports by destination rose from 3,125 to 7,397 (+137%). An HHI above 2,500 is generally considered highly concentrated; the current level reflects near-total dependence on a single destination market — the United States. This concentration creates a structural vulnerability: any disruption in US demand (tariffs, recession, sourcing shifts) would have an outsized impact on the EU's felt hat-form industry.

3. Import decline, supplier shifts, and the reshaping of EU production

China's share of EU imports fell but it remains the largest single supplier

EU imports from China declined from €4.8 million in 2015 to €2.2 million in 2025 (−54.3%), though China retained its position as the top extra-EU supplier. Several other traditional suppliers saw their trade collapse entirely:

The complete disappearance of Serbia, Taiwan, and Vietnam as suppliers suggests either the relocation of production back into the EU or a shift in EU sourcing patterns. Importantly, the import HHI fell from 6,372 to 4,277 (−33%), indicating a modest diversification of the remaining import base — even as the overall volume shrank.

EU production grew in value but stagnated in volume

According to production data, EU production in supplementary units (pieces) contracted 12.2% (from approximately 1.27 million to 1.12 million pieces), while production value surged by 778% (from €6 million to €52.7 million). This divergence — fewer pieces but far greater value — mirrors the export-side dynamics and strongly points to a shift toward higher-value-added felt components. The EU felt hat-form industry appears to have moved decisively upmarket, serving premium demand (particularly in the US) rather than competing on volume with Asian suppliers.

Italy's role shifted from import leader to mid-sized player

Italy was the EU's largest importer of CN 6501 in 2015 (€5.3M), but by 2025 its imports had fallen to €2.0M (−62.4%). This likely reflects the contraction of Italy's downstream hat-making industry or a reshoring of felt-form production. Meanwhile, Spain (+294%) and Ireland (+348%) saw import increases, suggesting emerging or relocating downstream activity.

Conclusion

The EU's trade in felt hat-forms (CN 6501) over 2015–2025 tells a story of industrial transformation. A niche, semi-finished product has become the basis of a strongly export-oriented European industry — one that is simultaneously more concentrated (in terms of both destination and producer), more premium-positioned (with unit values roughly doubling), and structurally less dependent on imports. Portugal, in particular, has emerged as a global powerhouse, channelling the vast majority of EU output to the United States. However, this very success creates concentration risk: with an export HHI of nearly 7,400 and the US absorbing an estimated 86% of extra-EU exports, the EU's felt hat-form sector is heavily exposed to shifts in a single market. The dramatic decline of imports from traditional Asian and Balkan suppliers, combined with rising EU production values despite flat volumes, points to a decisive move upmarket — a strategic repositioning that has so far yielded substantial gains but warrants monitoring for sustainability and diversification.
