EU Anti-Coercion Instrument: How the EU Now Fights Economic Bullying — and What It Means for UK Supply Chains

What the Anti-Coercion Instrument Is Designed to Do#

The EU Anti-Coercion Instrument (ACI) addresses a specific and growing problem: third countries applying economic pressure — trade restrictions, export controls, market access barriers — to force changes in EU or member-state domestic policy. The canonical example was China's informal trade restrictions on Lithuanian exports after Lithuania allowed Taiwan to open an office in Vilnius. The ACI gives the EU a formal legal mechanism to investigate such coercion, engage diplomatically, and if necessary respond with countermeasures. The instrument was designed after the EU found it had limited legal tools to respond proportionately to economic coercion without triggering WTO disputes. It represents a significant shift in EU trade defence architecture — moving beyond unfair pricing (anti-dumping) and foreign subsidies to address geopolitical use of trade leverage.

How It Differs from Anti-Dumping and Countervailing Duties#

Anti-dumping duties respond to products being sold in the EU below their normal value. Countervailing duties respond to foreign government subsidies that distort competition. Both target specific products and specific economic behaviours. The ACI operates differently: it responds to a third country's political conduct — the use of trade measures to influence EU policy — rather than specific product pricing. The ACI can authorise a broad range of countermeasures, including tariffs on goods from the coercing country, restrictions on services trade, restrictions on intellectual property protections, restrictions on public procurement access, and restrictions on foreign direct investment. This makes the ACI potentially broader in scope than product-specific anti-dumping measures. An ACI activation could affect entire product categories, services, or investment flows, not just specific goods subject to dumping investigations.

The Investigation Process and Countermeasure Trigger#

ACI investigations begin with the Commission examining whether a third country is engaging or threatening economic coercion. The Commission assesses: whether a measure applied by the third country has no justification under international law; whether the measure constitutes interference in the EU's or a member state's legitimate policy choices; and whether the measure causes economic harm to the EU or member state. The Commission must first engage diplomatically and attempt to resolve the situation through consultation and engagement. Only if engagement fails can it propose countermeasures, which require a qualified majority vote in the Council. The graduated approach is designed to de-escalate rather than immediately retaliate. However, the existence of the instrument itself is expected to deter coercive behaviour — countries know the EU now has a formal response mechanism.

Current Cases and Geopolitical Context#

No ACI countermeasures have been formally activated as of early 2025. The instrument has been used diplomatically — as leverage in EU foreign trade discussions — rather than through formal investigation. However, the geopolitical context in which it exists is highly relevant to trade risk. EU-China trade tensions over Lithuanian issues, concerns about potential coercion related to Taiwan policy, and disputes about EU solar panel and EV subsidy investigations all sit within the framework the ACI is designed to address. For businesses with supply chains dependent on specific EU-China trade flows, the ACI represents a category of regulatory risk that anti-dumping monitoring does not capture: geopolitical trigger events that could result in broad trade countermeasures affecting entire supply chains. AskBiz tracks trade defence measures including ACI developments alongside anti-dumping and subsidy investigations.

Implications for UK Businesses in EU Supply Chains#

UK businesses are not directly subject to ACI countermeasures — the instrument targets third-country behaviour, not UK businesses. However, UK businesses with significant exposure to EU supply chains face indirect risk from ACI activation in several ways. If the EU activates countermeasures against a country on which your supply chain depends for materials or components, your EU customers may face restrictions on procuring those goods — affecting demand for your products. If the ACI results in restrictions on services or procurement, UK businesses acting as subcontractors or suppliers to EU public procurement contracts may be affected if they source from the country subject to countermeasures. ACI risk requires the same supply chain mapping and geographic risk assessment as other trade policy risks.

• The EU Anti-Coercion Instrument (ACI), Regulation (EU) 2023/2675, entered into force in December 2023.
• It gives the EU a formal mechanism to investigate and respond to third-country economic coercion — where a country applies or threatens trade or investment pressure to influence EU or member-state policy choices.
• This is distinct from anti-dumping or countervailing duties and has significant implications for businesses caught in geopolitical trade disputes.
