China plans to impose a consumption tax on traditional batteries, with limited impact on energy storage costs but favorable implications for new technology pathways

Overview

This report is Bernstein’s flash commentary on China’s battery consumption tax policy. On July 16, 2026, China’s Ministry of Finance, General Administration of Customs, and State Taxation Administration issued Announcement No. 20 of 2026, introducing a phased consumption tax on certain battery products. The policy mainly covers traditional battery products produced, processed, sold, imported, or self-used within China, with core affected products including lithium-ion batteries, LFP, NMC, nickel-metal hydride batteries, and vanadium flow batteries. The report believes the policy is intended to curb industry overcapacity and capital expenditure expansion while encouraging new technology pathways such as sodium-ion and solid-state batteries.

Core views

The core views are: first, the consumption tax creates upward pressure on battery prices and energy storage system costs, but the magnitude is relatively manageable; second, exported batteries retain existing consumption tax rebate/exemption arrangements, so compliant exports do not bear additional consumption tax; third, second-tier battery manufacturers have thinner margins, and if they cannot pass costs downstream, profit pressure will become more evident; fourth, although CATL may be affected by negative headlines in the short term, its exports, new technology positioning, and market leadership keep its long-term risk-reward attractive; fifth, the policy may drive the industry away from traditional lithium battery capacity expansion toward emerging technologies such as sodium-ion and solid-state batteries.

Analysis framework

The report’s main analytical framework consists of breaking down policy provisions, conducting price sensitivity analysis, assessing cost pass-through across the industry chain, and comparing company valuations. The price analysis compares cost changes for LFP and NMC at the cell and battery pack levels under 2% and 4% tax rates, and further maps these changes to energy storage system costs. At the company level, the report focuses on CATL’s A-share and H-share valuation, target price, earnings forecasts, and risk factors.

Methodology notes

• Policy Impact AnalysisPhased Consumption Tax Rate Analysis

  Break down policy impact by battery product type, applicable tax rate, and implementation date

  The report separately maps the 2% tax rate from September 2026 and the 4% tax rate from September 2027 to cell, battery pack, and energy storage system costs to determine whether demand impact will be significant.

• Valuation MethodDCF

  Discounted cash flow valuation

  CATL’s A-shares use a 9.6% WACC and 3% terminal growth rate, while its H-shares use a 10.4% WACC and 3% terminal growth rate, with cash flow forecasts extending to 2050 and including a terminal value.

• Industry Structure AnalysisOvercapacity and Cost Pass-through Analysis

  Assess the differentiated policy impact on market leaders and second-tier manufacturers

  The report argues that second-tier battery manufacturers with thinner margins will find it harder to absorb the tax burden, and the policy may restrain their capacity expansion and promote long-term industry consolidation.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• Contemporary Amperex Technology Co Ltd (3750.HK)

  Directly relevant covered company and investment target

  Strengths

  Strong market leadership, exports not affected by the additional consumption tax, among the industry leaders in commercializing sodium-ion and solid-state batteries, H-share target price of HKD770.

  Weaknesses

  Domestic sales of traditional lithium batteries may face rising costs or margin pressure, and the recent share price has already been weak.

  Comparison

  Compared with second-tier battery manufacturers, CATL is better able to absorb the policy shock through scale, technology, and customer mix.

  Risks

  Overcapacity in China’s battery manufacturing, geopolitical constraints on market share, and intensifying competition from vertically integrated OEMs.

• Contemporary Amperex Technology Co Ltd (300750.CH)

  The same company’s A-share listing

  Strengths

  DCF target price of RMB800, with the report forecasting 20%-30% revenue CAGR over the next five years and A-share valuation at about 13x 2027E P/E.

  Weaknesses

  The policy is not a positive factor for the traditional battery business, and if the tax burden cannot be passed through, profits may be compressed.

  Comparison

  The A-share valuation framework differs from that of the H-shares, but the report maintains a positive rating framework on both.

  Risks

  Overcapacity in China’s battery manufacturing, geopolitical constraints on market share, and intensifying competition from vertically integrated OEMs.

• Second-tier battery manufacturers

  Industry group affected by the policy

  Strengths

  If they can shift to new technology pathways, they may benefit from the tax incentive window.

  Weaknesses

  Thin margins, weak ability to absorb the consumption tax, and capacity expansion plans may be restrained.

  Comparison

  Relative to market leaders such as CATL, second-tier manufacturers are more vulnerable in cost pass-through and technology upgrading.

  Risks

  Demand slowdown, price competition, overcapacity, and the added burden of policy taxation.

• Sodium-ion batteries and solid-state batteries

  Emerging technology pathways encouraged by policy

  Strengths

  Exempt from consumption tax through the end of 2028, and the report expects they could account for about 10%-20% of China’s total battery output by 2030.

  Weaknesses

  Still in the early stages of large-scale commercialization, and tax treatment after the end of 2028 remains unclear.

  Comparison

  Compared with mature lithium battery pathways such as LFP and NMC, new technologies receive more favorable tax treatment under the policy.

  Risks

  Uncertainty around commercialization progress, compliance with national standards, testing and certification, and the pace of cost decline.

Impact & implications

In the short term, the policy will raise the tax burden and cost of domestic sales of traditional batteries, but the impact on end-demand for energy storage may be limited. More importantly, the impact lies at the industry structure level: on one hand, it suppresses low-margin, over-expanding second-tier manufacturers; on the other hand, it encourages manufacturers to shift toward new technologies such as sodium-ion and solid-state batteries through differentiated tax treatment. For CATL, the report believes the negative headline does not change its long-term attractiveness, because its export business and new technology pathways are not directly affected, and industry consolidation may strengthen the advantages of market leaders.

Risks

• If the consumption tax cannot be passed on to downstream OEMs, it will directly compress battery manufacturers’ profit margins.
• China’s battery industry, especially second-tier manufacturers, faces overcapacity risk.
• Geopolitical factors may limit the overseas market share of Chinese battery companies such as CATL.
• Intensifying competition from vertically integrated OEMs may compress the bargaining power of battery suppliers.
• The arrangement for the tax exemption policy on emerging technologies after the end of 2028 remains unclear.
• To qualify for tax exemption, companies must meet national standards and CMA-qualified testing report requirements; insufficient compliance will prevent them from enjoying the incentive.

What to watch

• Battery company pricing and contract repricing after the consumption tax takes effect on September 1, 2026.
• After the tax rate rises to 4% on September 1, 2027, the extent of cost pass-through to battery packs and energy storage systems.
• Whether second-tier battery manufacturers slow capacity expansion or whether industry consolidation emerges.
• The commercialization progress and production share of sodium-ion and solid-state batteries in China.
• The differentiated impact between consumption tax rebate/exemption treatment for exported batteries and VAT export rebates.
• The share price reaction of CATL’s A-shares and H-shares to the policy news and the progress of valuation recovery.
