China plans to impose a consumption tax on lithium batteries; CATL faces short-term pressure but long-term risk-reward remains attractive
Bernstein believes that the 2% to 4% battery consumption tax will modestly raise costs, but have limited impact on energy storage demand, while potentially accelerating the exit of second-tier capacity and the transition toward sodium-ion and solid-state batteries.
- Starting September 1, 2026, products such as rechargeable lithium-ion batteries will be subject to a 2% consumption tax, rising to 4% from September 1, 2027.
- LFP and NMC cell prices are US$54.8/kWh and US$66.2/kWh, respectively; the tax pass-through at the battery pack level is estimated at about 1% in 2026 and about 3% in 2027.
- Energy storage system costs are expected to rise by 1-2% by 2027, which the report believes will have limited material impact on demand.
- Emerging technologies such as sodium-ion batteries, solid-state batteries, and fuel cells will remain exempt from consumption tax at least through the end of 2028.
- The policy may restrain capacity expansion by second-tier battery makers and promote industry consolidation; while not a positive headline for CATL, exports and new technology positioning are not directly affected.
Report interpretation
Overview
This report comments on the battery consumption tax policy jointly announced by China's Ministry of Finance, General Administration of Customs, and State Taxation Administration on July 16, 2026. The policy ends the battery industry's broad tax exemption that had lasted for 11 years, introducing phased taxation on mature technologies such as traditional lithium batteries while continuing to support emerging technologies such as sodium-ion and solid-state batteries. Bernstein believes that in the short term this policy will increase battery companies' costs or squeeze margins, but will have limited impact on end-market energy storage demand; the policy intent is more geared toward curbing excess capacity and guiding technology upgrades.
Core views
The core views include: first, the consumption tax on lithium-ion batteries will be 2% starting in September 2026 and rise to 4% in September 2027, mainly applying to domestic production, processing, imports, and certain internal-use cases in China. Second, after tax pass-through to battery packs and energy storage systems, the cost increase is smaller than at the cell level and is not expected to materially impair long-term demand. Third, export consumption tax rebate and exemption policies remain unchanged, and qualifying battery exports will not bear additional consumption tax. Fourth, the policy puts greater pressure on low-margin second-tier manufacturers, potentially limiting excessive capacity expansion and promoting higher industry concentration. Fifth, the tax exemption for sodium-ion and solid-state batteries sends a clear policy signal favorable to the transition toward next-generation battery technologies.
Analysis framework
The report combines policy clause breakdown, tax-rate scenario modeling, supply-chain cost pass-through analysis, and company valuation comparison, with a focus on assessing the impact of the consumption tax on cell, battery pack, and energy storage system costs, industry capacity discipline, and the investment case for CATL.
Methodology notes
Deriving battery pack and energy storage system cost changes from cell tax-rate changes
The report maps the 2% and 4% consumption tax rates to LFP and NMC cell prices, then observes the resulting cost increases at the battery pack and ESS system levels to judge end-demand sensitivity.
Discounted cash flow valuation
The report uses the DCF method to value CATL's A-shares and H-shares, assuming a WACC of 9.6% and terminal growth rate of 3% for A-shares, and a WACC of 10.4% and terminal growth rate of 3% for H-shares, with cash flow forecasts through 2050.
Asset mapping & comparison
Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).
- Contemporary Amperex Technology Co Ltd (3750.HK)One of the report's key covered companies; H-shares maintained at Outperform with a target price of HKD770.
- Strengths
- Market leadership, exports not affected by the additional consumption tax, and an industry-leading position in the commercialization of sodium-ion and solid-state batteries.
- Weaknesses
- The lithium battery consumption tax is not positive news; if it cannot be passed downstream, margins will be compressed.
- Comparison
- Compared with second-tier battery manufacturers, CATL is more likely to benefit from policy-driven industry consolidation and the clearing of excess capacity.
- Risks
- Excess battery manufacturing capacity in China, geopolitical restrictions on market share, and intensifying competition from vertically integrated OEMs.
- Contemporary Amperex Technology Co Ltd (300750.CH)One of the report's key covered companies; A-shares maintained at Outperform with a target price of RMB800.
- Strengths
- According to the report, valuation is about 13x 2027E P/E, revenue is expected to maintain a 20-30% CAGR over the next five years, and risk-reward remains attractive.
- Weaknesses
- Domestically sold related products may face consumption tax-related cost or margin pressure.
- Comparison
- Both A-shares and H-shares are driven by the same fundamentals and policy logic, but target prices and WACC assumptions differ.
- Risks
- Excess battery manufacturing capacity in China, geopolitical restrictions on market share, and intensifying competition from vertically integrated OEMs.

Impact & implications
For the industry, the consumption tax means that traditional lithium battery technology is shifting from broad-based tax exemption to differentiated taxation based on technological maturity, with cost pressure more likely to test low-profit, over-expanding second-tier manufacturers. For demand, the cost increase after tax pass-through to energy storage systems is limited, so long-term electrification and energy storage demand should not be materially weakened. For investors, CATL may face short-term headline pressure from the policy, but its export business, emerging technology positioning, and leadership benefits from industry consolidation still support the Outperform rating.
Risks
- Excess battery manufacturing capacity may continue to pressure industry pricing and margins.
- If battery companies cannot pass the consumption tax on to OEMs or end customers, margins will be hit.
- Geopolitical factors may constrain CATL's market share and export expansion.
- Competition from vertically integrated OEMs may weaken the bargaining power of third-party battery suppliers.
- The post-2028 tax treatment of emerging technologies such as sodium-ion and solid-state batteries remains unclear.
What to watch
- How pricing pass-through develops after the 2% consumption tax takes effect on September 1, 2026.
- Changes in battery pack and ESS system costs after the tax rate rises to 4% on September 1, 2027.
- Whether second-tier battery manufacturers slow capital expenditure and capacity expansion plans.
- Whether CATL continues to advance the commercialization of sodium-ion and solid-state batteries.
- Whether the market confuses or further policy changes occur regarding export consumption tax rebates/exemptions and VAT export rebates.
- Execution of the national standard compliance documents and CMA testing reports required for companies to apply for tax exemption.
