Summary of Key Points
Starting from September 2026, a 2% consumption tax will be levied on lithium batteries (rising to 4% in 2027), while sodium-ion, solid-state, and fuel cells will be exempt from taxation until the end of 2028. This is not a sudden change. The exemption over the past 11 years was designed to support the nascent lithium battery industry, which now accounts for over 80% of global production. With China's lithium battery industry having matured, the policy shift focuses on regulating and promoting technological advancement. The industry has responded differently: some battery manufacturers have rushed to sell inventory before the tax takes effect, while others have adjusted prices to pass on the cost. Automakers, with extremely low profit margins (only 1.5%), are struggling to absorb these increases. Companies that produce their own batteries, such as BYD, are more flexible, as they are less affected by the tax on smaller battery-powered vehicles (including hybrid models). The policy also encourages the development of new technologies like sodium-ion batteries, aiming to transition the industry from being subsidy-driven to technology-driven.
Detailed Analysis
Why the Policy Change?
The exemption on lithium batteries was akin to parental support for a child learning to walk—helping the industry grow. In 2015, China's lithium battery capacity was small, and the exemption allowed companies to invest in research and expansion. Now, with China accounting for 80% of global production and annual electric vehicle sales exceeding 10 million units, the industry has matured. Continuing the exemption would be like giving benefits to established companies rather than supporting them. The logic behind the policy change is simple: let mature industries bear the normal tax burden and allocate resources to newer, more needs-based technologies (such as sodium-ion and solid-state batteries), just as a child grows up and needs to fend for themselves.
How Are Battery Manufacturers Responding?
Before the tax, some manufacturers tried to maximize profits by selling inventory quickly, as orders placed before September were exempt from the tax. For example, a 500 million yuan contract could save 10 million yuan in costs. However, different companies reacted differently:
- Leading companies (like CATL) remained calm, using negotiation with major customers to share the cost burden, while smaller customers may have to bear the increase on their own.
- Mid-tier companies (like EVE Energy) directly raised prices, passing on the tax increase to their products starting in September.
- Smaller manufacturers faced the biggest challenges, as they lacked scale and bargaining power, with their already thin margins being further squeezed by the 2% tax.
This process will lead to a consolidation of the industry, with leading companies becoming stronger and smaller ones possibly being eliminated.
The Struggle for Automakers
The increased cost pressure on battery manufacturers will be passed on to automakers, which are already struggling with low profit margins of only 1.5%. For example, a 150,000 yuan electric vehicle with an 80 kWh battery would see the battery cost increase by 1,200 yuan due to the tax, potentially wiping out all profit. Automakers cannot easily raise prices in the current competitive market, so they must absorb these costs, further squeezing their profit margins.
The most vulnerable are those without their own battery production capabilities and with low sales volumes, as they are squeezed by both battery manufacturers and the market.
Who Can Survive the Pressure?
Companies that produce their own batteries and those with large market shares are better positioned to handle the changes:
- Companies with in-house battery production (like BYD and Great Wall) can adjust costs more flexibly and are less dependent on external suppliers.
- Large customers (like Tesla), with significant purchasing volumes, have bargaining power and can share the cost burden with suppliers.
Smaller, less established brands will face greater challenges, especially as the tax rate rises to 4% in 2027, potentially leading to survival crises.
The Impact on Technology
The policy also shifts the competitive landscape:
- Hybrid vehicles become more attractive: Hybrid batteries have smaller capacities and lower tax burdens, making them more cost-effective compared to pure electric vehicles.
- New technologies are favored: Exemptions for sodium-ion, solid-state, and fuel cells encourage investment in these technologies. For instance, BYD's DM-i hybrid model benefits from lower tax costs due to its smaller battery size.
The policy aims to shift the industry from relying on subsidies to focusing on innovation. The era of growth driven by subsidies is coming to an end, and the future depends on genuine technological advancements.
In Conclusion
This tax adjustment marks the transition of China's lithium battery industry from its infancy to maturity. While it may result in slightly higher costs for consumers, hybrid vehicles become more cost-effective. For companies, it means either improving efficiency and reducing costs or facing elimination. Industrial transformation is always brutal but necessary.
