U.S. Exempts Cork From 15% EU Tariff, Easing Pressure on Winemakers and Portuguese Producers
Trade framework spares cork as an “unavailable natural product,” shielding a key input for wine bottles and a major export for Portugal

The United States has exempted cork from a 15% tariff on most European Union products under the framework trade agreement between the two sides, a move that took effect Sept. 1 and removes a potential cost burden for U.S. winemakers and Portuguese cork producers.
Cork, harvested from the spongy bark of the cork oak tree that grows primarily in the Mediterranean basin, was singled out in the agreement as an “unavailable natural product” and therefore outside the scope of the tariff. The carve-out places cork alongside a small list of other exemptions, including airplanes and generic pharmaceuticals.
The exemption was particularly significant for Portugal, the world’s largest cork producer, which supplies roughly half of global production. Portuguese diplomats lobbied on both sides of the Atlantic to secure the reprieve, arguing that tariffs on cork would have disproportionate economic effects in regions where cork harvesting and processing support rural employment.
U.S. industry advocates also pushed for the exemption. Patrick Spencer, executive director of the Natural Cork Council in the United States, traveled from Salem, Oregon, to Washington in June to brief U.S. trade officials on cork’s origin and production and to request a tariff reprieve. Industry groups representing wine producers raised concerns that a tariff on cork could increase costs for bottlers and disrupt supply chains.
Tariffs on imports from the European Union had been proposed as part of broader trade measures, and the framework agreement negotiated between the United States and EU identified certain products for exclusion on the basis of availability, strategic importance or potential economic harm. Cork was designated an unavailable natural product, reflecting its limited growing range and concentrated global supply.
Analysts and industry representatives said the exemption avoids a direct, short-term price shock for U.S. winemakers who currently use natural cork stoppers. The material remains the dominant closure for many premium wines and carries cultural and technical associations that many producers and consumers prefer to alternative closures such as screw caps or synthetic corks.
Portugal’s cork sector is not only a supplier to the global wine industry but also a driver of employment in its cork-producing regions, where trees are harvested by hand every nine to 12 years without felling. Removing cork from the tariff list reduces the risk that export demand would be disrupted, a concern Portuguese officials flagged during diplomatic engagements.
The framework agreement that produced the exemption aimed to balance U.S. trade leverage with efforts to avoid unintended damage to industries deemed sensitive or uniquely sourced. By exempting cork, negotiators acknowledged the concentrated geography of cork production and the potential consequences that tariffs could have on rural economies in Portugal and other Mediterranean countries.
The exemption does not affect other contested tariff measures or trade disputes between the United States and the European Union, and it applies specifically to cork as defined under the trade terms. Industry groups said they will continue to monitor how the exemption is implemented at ports and through customs procedures to ensure there are no administrative hurdles that could effectively reintroduce costs for importers.
For U.S. winemakers and Portuguese suppliers alike, the decision removes a looming cost uncertainty and preserves the status quo for a centuries-old material closely tied to wine bottling and regional economies in cork-producing areas of the Mediterranean.
