BYD’s Polish Battery Bet and European Growth Face Pivotal EU Tariff Decision

BYD shares hover near 52-week low as EU prepares hybrid tariff vote, despite record European registrations, a Polish battery project, and Hungarian factory ramp-up.

The Shenzhen-based automaker finds itself navigating a widening gap between bullish operational momentum and a regulatory overhang that keeps its stock pinned near the floor. BYD shares changed hands at €8.96 on Tuesday, barely above the 52-week low of €8.03 hit in late June, as investors weigh an imminent EU vote on hybrid tariffs against a string of international expansion milestones that include a 2.4 GWh battery storage project in Poland and record European vehicle registrations.

First, the encouraging moves. BYD is powering ahead with a massive energy-storage installation in Siedlce, Poland, built for long-time partner Greenvolt Power. The facility will use BYD’s Haohan system, which relies on the company’s proprietary blade battery technology. Construction is slated to start in the third quarter of 2026, with commercial operations expected by the end of 2027. On the automotive side, the group’s factory in Szeged, Hungary, is ramping up production, and management is scouting a second European site – possibly through the acquisition of existing plants in France or Spain. The payoff is already visible: BYD posted a record 6,200 registrations in Germany in June, and its local subsidiary is targeting 50,000 vehicles for the full year.

June’s global sales figures underscore the widening divergence between BYD’s domestic and overseas fortunes. The company delivered roughly 403,000 cars worldwide, with international sales nearly doubling to more than 175,000 units. In China, however, sales slumped 22 percent, a drop that reflects the brutal price war and structural overcapacity gripping the domestic auto sector. That weakness has been the primary drag on the stock, which has lost nearly 19 percent since the start of 2025.

Now the tariff shadow. The European Commission is preparing fresh import duties on Chinese plug-in hybrids, the vehicle category that has been the main engine of BYD’s European sales surge. In May 2026, BYD overtook all rivals to become Germany’s top plug-in hybrid brand with 4,290 new registrations. The Commission had denied such tariffs were coming as recently as January, but the policy shift is now all but confirmed. The exact rate remains unknown and requires approval from EU member states. BYD already faces a 17.0 percent compensatory tariff on its pure electric vehicles, and any similar levy on hybrids would directly threaten the company’s European growth story. Simultaneously, talks on minimum pricing are under way; a deal could effectively replace the tariffs and remove the uncertainty.

The legal front adds another layer of complexity. BYD, together with Geely and SAIC, is challenging the existing EV tariffs at the European Court of Justice, a process expected to take around 18 months. Until a ruling arrives, the shares will remain exposed to regulatory news flow.

The stock’s chart reflects the deep indecision. It trades roughly 10 percent below its 50-day moving average, and the relative strength index sits in neutral territory. In the bull case, even a moderate tariff or a compromise on minimum prices could lift the shares toward the €10.00 mark, especially given the product offensive BYD is staging at the Goodwood Festival of Speed starting July 9. The company is unveiling eight new models from three brands, with the premium DENZA line taking centre stage as it makes its official UK debut. Higher-margin brands like DENZA and YANGWANG are central to BYD’s strategy of escaping the low-margin mass market at home, and international markets are expected to contribute a growing share of profits over time.

In the bear case, the combination of China’s persistent price pressure and a meaningful hybrid tariff could push the stock back to test the year’s low at €8.03. For now, the decisive catalyst is the impending vote among EU member states, expected within weeks. Until that verdict lands, the shares are likely to remain stuck in a narrow range, tugged between a promising global expansion and a trade policy that could slam the door on the very vehicle type driving that growth.
