Transatlantic Tug-of-War: The EU's Balancing Act Against Shifting US Trade Policies

Brussels is navigating a complex and often unpredictable trade landscape, as the European Union confronts a resurgence of protectionist rhetoric and tariff threats from the United States, even as it seeks to solidify avenues for cooperation. The long-standing economic partnership, valued at over €1.6 trillion in goods and services in 2023, is frequently tested by American "dealmaking" strategies, requiring the EU to employ a delicate balance of diplomatic engagement, strategic patience, and the readiness to retaliate. The coming months are poised to define the future trajectory of this critical transatlantic relationship, with key disputes over steel, aluminum, digital services, and automotive trade demanding urgent attention and decisive responses.

Navigating the Tariff Minefield: A Legacy of Disputes

The recent era of transatlantic trade friction largely began in 2018 when the US, under the then-Trump administration, invoked Section 232 of the Trade Expansion Act of 1962 to impose tariffs of 25% on steel and 10% on aluminum imports, citing national security concerns. These measures, which targeted approximately €6.4 billion of EU goods annually, were met with swift and proportionate rebalancing measures by the European Commission, affecting €2.8 billion worth of US goods. The EU viewed these tariffs as "unjustified trade restrictions" and a challenge to the multilateral trading system. This tit-for-tat dynamic established a precedent for the EU's response: while preferring negotiation, it would not shy away from defending its economic interests.

The Evolving Landscape of Steel and Aluminum Tariffs

The approach to the steel and aluminum tariffs shifted under the Biden administration. In January 2022, the US suspended the Section 232 tariffs on EU steel and aluminum, replacing them with a Tariff Rate Quota (TRQ) system that allowed a fixed volume of EU metal imports to enter the US duty-free, while volumes exceeding these quotas remained subject to the original tariffs. This agreement also led the EU to suspend its retaliatory tariffs on US products, such as Harley-Davidson motorcycles, bourbon whiskey, and Levi's jeans. The initial suspension was extended for two years until December 31, 2025, providing a framework for continued negotiations aimed at finding comprehensive solutions to overcapacity and promoting low-carbon production through a proposed Global Arrangement on Sustainable Steel and Aluminum.

However, the path forward remains fraught with uncertainty. As of May 2025, the "Trump II" administration has reportedly re-imposed some steel and aluminum tariffs, leading the EU to approve new trade countermeasures targeting approximately €18 billion of US-origin products. These measures complement existing countermeasures from 2018 and 2020. In a bid to facilitate ongoing negotiations, the EU announced a 90-day pause on these renewed countermeasures. The EU continues to push for the US to lower steel and aluminum tariffs to a 15% ceiling as part of broader trade discussions.

Beyond Metals: Aircraft Subsidies, Digital Taxes, and Automotive Threats

The EU-US trade relationship has been marked by several other high-profile disputes. A long-running disagreement over government subsidies to aircraft manufacturers, Boeing in the US and Airbus in the EU, resulted in retaliatory tariffs from both sides over a 17-year period. This dispute saw the US awarded $7.5 billion in WTO-authorized tariffs against the EU in 2019, while the WTO also found the US had provided illegal subsidies to Boeing. This contentious chapter saw a significant step towards resolution in 2021 when the Biden administration and the EU agreed to suspend these tit-for-tat tariffs for five years, signaling a renewed commitment to cooperation.

Another significant area of contention involves Digital Services Taxes (DSTs). Several EU countries have implemented DSTs, aimed at taxing the profits of large digital platforms, many of which are US-based. The US government has consistently voiced bipartisan opposition to these taxes, viewing them as discriminatory and threatening retaliatory tariffs under Section 301. While the OECD has pursued a global solution for corporate income tax-shifting by multinationals, including digital platforms, the digital tax question remains largely unresolved, with US officials noting that the EU continues to advocate for a bloc-wide DST.

More recently, the automotive sector has become a flashpoint. In early May 2026, former President Donald Trump reportedly threatened to increase tariffs on EU cars and trucks to 25%, up from a previously agreed 15% cap, claiming the EU was not complying with a trade deal struck in July 2025. This threat has put immense pressure on EU lawmakers and governments to finalize legislation that would eliminate duties on US industrial goods in return for the 15% US tariff ceiling on most EU exports. European Parliament's chief negotiator, Bernd Lange, emphasized the need for strong safeguard mechanisms, including a "sunrise clause" that would make new tariffs effective only if the US honors its commitments, and a "sunset clause" for preferences to expire by March 2028. These ongoing negotiations highlight the EU's resolve to protect its industries while seeking stable trade relations.

The EU's Strategic Playbook: Diplomacy and Defense

The EU's overall strategy in dealing with US trade "dealmaking" is characterized by a multi-pronged approach that combines diplomatic engagement with a firm defense of its interests and the multilateral trading system. The EU consistently prioritizes negotiation as the first course of action, seeking agreement to avoid disruptive tariff wars. When faced with tariff threats or perceived economic coercion, the EU is prepared to implement proportionate countermeasures, leveraging its position as a unified economic bloc.

A significant development in recent years has been the establishment of the Transatlantic Trade and Technology Council (TTC) in June 2021 by the Biden administration and the EU. This forum aims to coordinate approaches on key global trade, economic, and technology issues, deepen transatlantic trade relations, and promote shared democratic values. The TTC has ten working groups covering areas such as technology standards, climate and clean tech, secure supply chains, and global trade challenges. While the TTC offers a platform for cooperation on strategic issues, it operates alongside, and sometimes independently of, the more immediate tariff disputes.

The EU also remains a strong proponent of the World Trade Organization (WTO) dispute settlement mechanism, utilizing it to resolve some of its most contentious issues with the US, even as it acknowledges the WTO's limitations. The EU’s commercial policy, spoken with a single voice through the European Commission, represents a united front in these international forums. However, internal divisions within the EU itself can sometimes slow down the ratification of trade agreements, as seen in the ongoing discussions to finalize the deal concerning US industrial goods and automotive tariffs.

Conclusion

The European Union's engagement with US trade policy is a dynamic and ongoing balancing act. It involves navigating the immediate challenges of tariff threats, resolving legacy disputes, and simultaneously building cooperative frameworks for future economic and technological collaboration. The EU's consistent message is one of openness to negotiation, coupled with a readiness to defend its interests through proportionate measures and adherence to international trade rules. As US administrations shift their approaches, the EU has demonstrated an adaptive strategy, seeking stability and predictability while safeguarding its market and industries. The efforts to secure a durable and mutually beneficial transatlantic trade relationship continue, demanding constant vigilance and strategic diplomacy from Brussels.
