China's Battery Tax Reform May Accelerate In-House Cell Production

China’s upcoming shift in battery consumption tax could give automakers a major incentive to produce their own battery cells, according to Cui Dongshu, secretary-general of the China Passenger Car Association (CPCA). In a recent analysis, Cui highlighted that vehicle manufacturers who make batteries in-house would be exempt from or could deduct the consumption tax, while those relying on external suppliers would face additional costs.

This policy change is seen as a strategic move by Beijing to encourage vertical integration in the electric vehicle industry. By making outsourced batteries more expensive, the government aims to push automakers to secure their supply chains and invest in cell manufacturing capabilities. Experts suggest this could reshape the competitive landscape, favoring companies with strong in-house battery divisions.

Cui’s remarks come amid a broader trend of automakers forming joint ventures or partnerships with battery giants like CATL, while a few leading players have already committed to producing their own cells. The tax mechanism is expected to accelerate such decisions, potentially reducing reliance on third-party suppliers in the long run.
