The European Union and the United Kingdom are negotiating changes to electric vehicle trade arrangements ahead of stricter manufacturing requirements scheduled for January 2027. Without an agreement, vehicles that fail to meet new local-content rules could face a 10% import tariff.

The discussions have become increasingly important for manufacturers that rely on international battery suppliers. Industry representatives warn that additional costs could undermine investment, weaken competitiveness and make electric vehicles more expensive.

Why New Tariffs Could Take Effect

The potential tariffs originate from the EU-UK Trade and Cooperation Agreement, which established trading arrangements following Brexit.

Under the agreement, electric vehicles must contain a specified proportion of components manufactured in Britain or the EU to qualify for tariff-free trade.

From 1 January 2027, at least 55% of an electric vehicle's value must originate in either market. Battery packs must meet a 70% local-content threshold, while individual battery cells must reach 65%.

Vehicles that fail to satisfy the applicable requirements could face a 10% tariff when crossing between the two markets.

These stricter rules were originally introduced to encourage investment in domestic battery manufacturing. However, developing the necessary production capacity has proved challenging.

Manufacturers Warn Of Rising Costs

The Society of Motor Manufacturers and Traders (SMMT) estimates that the proposed tariffs could threaten approximately £16.4 billion in electric vehicle trade between Britain and the EU.

Many manufacturers continue to purchase batteries and other essential components from Asian suppliers, making the new local-content thresholds difficult to achieve.

Additional tariffs could increase production costs and reduce the competitiveness of vehicles exported between the two markets.

Mike Hawes, chief executive of the SMMT, has warned that imposing additional costs on electric vehicles would undermine efforts to encourage their adoption.

Manufacturers are particularly concerned because the European and British automotive industries operate through closely connected supply chains.

Negotiations Offer Hope Of An Agreement

European Trade Commissioner Maroš Šefčovič and British Trade Secretary Jonathan Reynolds discussed the issue during a meeting alongside the G20 trade ministerial gathering in Milwaukee.

According to a British government account of the discussions, both sides recognised the importance of avoiding sudden tariff increases.

However, no final agreement has been announced.

The current arrangements were extended in December 2023, allowing manufacturers to continue trading under less demanding local-content rules until the end of 2026.

A further adjustment would require agreement between the relevant authorities.

Chinese Electric Vehicles Complicate Talks

The negotiations also intersect with broader disagreements over Chinese electric vehicle imports.

Since 2024, the EU has imposed additional duties on certain Chinese-made electric cars, while Britain has maintained a different approach.

Some European officials believe closer alignment would help prevent manufacturers from using Britain to bypass EU trade restrictions.

British authorities, meanwhile, must consider the interests of consumers, manufacturers and exporters before introducing similar measures.

The issue could also influence Britain's potential participation in the EU's proposed manufacturing support programmes.

What Happens Next For The Car Industry?

The approaching January 2027 deadline leaves manufacturers facing uncertainty over future trading costs.

A negotiated solution could preserve tariff-free access for more vehicles while giving battery producers additional time to expand European manufacturing capacity.

Without changes, companies relying heavily on imported components may face higher costs and greater pressure to reorganise their supply chains.

The outcome will influence investment decisions, vehicle pricing and the development of electric car production across Britain and the European Union.
