Sovereign cell supply

2027: the year sovereignty starts to win.

New battery sourcing rules take effect across the US, UK and EU in 2027. The same year, Volklec starts making 21700 cells in Coventry. If your programme depends on cells from outside allied supply chains, now is the time to plan the move.

What changes in 2027

Where your cells are made is becoming a procurement question.

For years, cell origin was a cost decision. From 2027 it starts to decide which contracts you can bid for, which markets you can sell into tariff free, and what you have to prove about your supply chain.

Now
UK defence

The Defence Industrial Strategy puts sovereign capability at the centre of UK procurement, and brings closer scrutiny of where critical components come from.

Affects: UK defence primes and their supply chains
1 Jan 2027
EU–UK trade

Stricter rules of origin under the Trade and Cooperation Agreement are due to apply: 65% UK or EU content for battery cells and 70% for packs. Electric vehicles that miss the rules face a 10% tariff at the border. Industry is lobbying for more time, but the direction is set.

Affects: automotive and off-highway trading across the Channel
18 Aug 2027
EU market

Larger companies placing batteries on the EU market must have supply chain due diligence policies in place, verified by a notified body and audited.

Affects: battery suppliers above the turnover threshold selling into the EU
1 Oct 2027
US defence

The Pentagon can no longer use its funds to buy batteries produced by six named Chinese manufacturers, including CATL and BYD. Who made the cells and components can matter, not just the brand on the pack. A further rule requires batteries in new US defence programmes to be free of Chinese components from 2028.

Affects: suppliers to US defence programmes
