Why Carmakers Want the EU and UK to Delay 2027 EV Battery Rules
European and UK carmakers are asking for the 2027 battery rules of origin to be postponed until 2030 after a transition through 2029. The final regime requires 55% of an EV’s value to originate in the EU or UK, alongside stricter battery origin requirements.

The dispute over EU–UK electric-vehicle trade is fundamentally about timing. Carmakers do not appear to be rejecting the goal of building a more regional battery supply chain; they are asking the EU and UK to avoid imposing the agreement’s strictest origin rules before that supply chain can support them.
What carmakers want changed
European manufacturers, represented by ACEA, are calling for the current, more flexible battery rules under the EU–UK Trade and Cooperation Agreement (TCA) to continue through 2029. Their reported proposal is for tougher localisation requirements to begin in 2030 rather than arrive abruptly on 1 January 2027. 6
That would be a second postponement. The EU and UK had already agreed in December 2023 to retain the then-current rules for three years, moving the original 2024 tightening to 2027. 2
What the 2027 rules of origin require
Rules of origin determine whether a product qualifies for the TCA’s zero-tariff treatment. From 2027, an EV traded between the EU and UK must meet the standard requirement that at least 55% of its value originate in the EU or UK. It must also satisfy specific, stricter origin conditions for its battery and battery components. 1
The battery is decisive because it represents a large share of an EV’s value. A vehicle assembled in Britain or the EU can still fail the overall origin test if key battery inputs are sourced from outside the two markets.
A vehicle or battery that does not meet the applicable requirements faces a 10% tariff at the EU or UK border. 1
Why the industry says supply chains are not ready
Carmakers say European and UK capacity for battery cells, components and upstream materials has not developed quickly enough to meet the 2027 thresholds. Their concern is that regional vehicle production will be tariffed because batteries and their inputs still depend heavily on supply chains outside the EU and UK. 3
6
The argument is therefore not simply about customs administration. It is about whether factories can obtain qualifying batteries at commercial scale before the rules become binding.
The potential trade impact
The exposure could be substantial. SMMT, the UK auto-industry body, estimated that British EV makers could face £1.4 billion in tariffs if no solution is reached; it said the rules could trigger a 10% tariff on 70% of battery-electric and plug-in-hybrid models traded with the EU.
ACEA, meanwhile, warned that 82% of EU EV exports to the UK could otherwise face tariffs. 6
These are industry estimates, not a forecast of the tariffs that will definitely be paid. Actual exposure will depend on model-specific sourcing and whether manufacturers can change their supply chains or absorb the cost. But the figures explain why the groups are seeking a negotiated revision before 2027.
Why the request is especially urgent now
The prospect of an internal EU–UK tariff arrives while European manufacturers face intense competition in electric vehicles and continued pressure to lower costs. A tariff on cross-Channel trade would add cost within a closely connected production and sales market rather than shield producers from imports.
It also sits alongside a more active EU trade policy toward China. In September, the European Commission said it was seeking commitments from China to address the widening EU–China trade gap. Separately, reports said the EU had asked China to voluntarily limit hybrid-vehicle exports, while the Commission has set conditions under which China-based EV makers could substitute minimum-price commitments for EU tariffs.
That contrast sharpens the carmakers’ case: while Brussels seeks to manage external competitive pressure, manufacturers want to avoid a 2027 rule change that could create new costs for EVs moving between the EU and UK.
The practical choice facing policymakers
The industry’s requested compromise is clear: keep the existing transitional regime through 2029, then introduce stricter localisation requirements from 2030. 6
Supporters see that as a way to preserve tariff-free trade while battery production and material supply scale up. The unresolved policy question is whether another delay would give Europe and the UK the time needed to build those supply chains—or merely defer a requirement designed to encourage that investment.
