China's lithium battery consumption tax takes effect; short-term impact is manageable, with leaders better positioned to pass it through

Overview

The report analyzes the impact of China's new battery consumption tax policy on the lithium-ion battery value chain, automakers, and energy storage projects. The policy taxes lithium batteries produced and sold domestically in China, at a rate of 2% from September 2026 and 4% from September 2027; sodium-ion and solid-state batteries receive temporary tax exemptions. The report believes the policy is not an unexpected shock, but is in line with prior market expectations and consistent with China's supply-side reform and industry consolidation direction in batteries.

Core views

The core views are: first, formal implementation of the policy removes uncertainty over the introduction of the lithium battery consumption tax; second, the consumption tax is recorded under taxes and surcharges below gross profit, so it does not affect revenue or gross margin but reduces operating profit, pretax profit, and net profit; third, if the tax burden cannot be passed downstream, profit pressure will increase substantially in 2027-2028; fourth, leading battery companies, particularly CATL, are better able to absorb or pass through the tax burden through customer mix, overseas revenue exposure, cost advantages, and pricing power; fifth, the policy may further squeeze smaller manufacturers, improving supply discipline and industry concentration.

Analysis framework

The report uses policy interpretation, accounting impact decomposition, a most pessimistic scenario analysis, and value-chain cost pass-through analysis. The calculations assume that battery manufacturers fully absorb the consumption tax without passing it on to customers, using the share of domestic China revenue in 2025 as the revenue mix assumption for 2026-2027. It then estimates the impact of consumption tax expenses on operating profit, pretax profit, and net profit, and discusses the ability of downstream EV and ESS customers to absorb price increases.

Methodology notes

• Scenario analysisMost pessimistic full tax absorption scenario

  Consumption tax fully borne by battery manufacturers

  Assumes battery companies do not pass the incremental consumption tax on to downstream customers, with the entire tax expense recorded under taxes and surcharges, thereby directly reducing operating profit and net profit.

• Policy accounting impactDistinguishing consumption tax from export tax rebate impacts

  Consumption tax does not affect gross profit, while export tax rebates do

  The report notes that consumption tax is recorded under taxes and surcharges below gross profit, so it does not change revenue or gross margin; changes to export tax rebates, however, affect gross profit and gross margin.

• Cost pass-through analysisPassing battery price increases through to EVs and ESS

  A 4% battery price increase has a limited impact on end-market costs but creates demand pressure

  Full pass-through would be equivalent to a 4% increase in battery prices, typically raising EV vehicle MSRP by approximately 0.5%-1% and reducing ESS project IRR by approximately 0.5-1 percentage points.

Asset mapping & comparison

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

• CATL - H (3750.HK)

  Largest beneficiary or relatively defensive name

  Strengths

  Higher overseas sales exposure, a larger profit buffer, stronger cost competitiveness and pricing power; approximately 80% of its China EV battery shipments correspond to B-class or higher-end models.

  Weaknesses

  Still subject to consumption tax on the portion of lithium battery sales made domestically in China, while downstream customer cost pressure may limit full pass-through.

  Comparison

  Compared with CALB, Gotion, and EVE, the report believes CATL would be least affected in the most pessimistic scenario.

  Risks

  Less-than-expected tax pass-through, weak downstream EV demand, and continued increases in material costs.

• CALB (3931.HK)

  One of the covered battery manufacturers affected by the policy

  Strengths

  Still rated OW by J.P. Morgan.

  Weaknesses

  Compared with the leader, its domestic revenue exposure and profit buffer may result in greater net profit pressure.

  Comparison

  Under the full tax absorption scenario, it would be more affected than CATL.

  Risks

  Inability to pass through the consumption tax, intensifying domestic market competition, and margin pressure.

• EVE Energy (300014.SZ)

  One of the covered battery manufacturers affected by the policy

  Strengths

  Has an established battery business footprint and is rated N.

  Weaknesses

  The report identifies it as one of the companies that may face more significant profitability pressure.

  Comparison

  Compared with CATL, its pricing power and profit buffer are considered weaker.

  Risks

  Net profit pressure from absorbing the tax burden, downstream customer bargaining power, and cost inflation.

• Gotion High-Tech (002074.SZ)

  One of the covered battery manufacturers more significantly affected by the policy

  Strengths

  Has battery production capacity and an established customer base.

  Weaknesses

  Rated UW; the report believes it is more likely to be constrained by domestic revenue exposure and weaker margins.

  Comparison

  Compared with CATL, its ability to pass through costs and its profit buffer are weaker.

  Risks

  Consumption tax impact, industry consolidation pressure, price competition, and declining profitability.

• Chinese EV automakers

  Potential cost bearers

  Strengths

  If battery manufacturers pass through the tax burden, the impact on end-market vehicle prices would typically be only approximately 0.5%-1%.

  Weaknesses

  Current sales are weak and cost inflation pressure exists, limiting their ability to absorb additional price increases.

  Comparison

  Unlike battery manufacturers, automakers are not the statutory taxpayers, but may share the tax burden through commercial negotiations.

  Risks

  Higher battery costs, weakening end-market demand, and price competition limiting cost pass-through.

• ESS projects

  Potential cost bearers

  Strengths

  Battery prices have already recovered significantly, making a 4% tax pass-through relatively modest compared with existing increases.

  Weaknesses

  Full pass-through could reduce project IRR by approximately 0.5-1 percentage points.

  Comparison

  ESS customers are sensitive to costs and returns, so tax pass-through may depend more heavily on project economics.

  Risks

  Lower project returns, delayed orders, and customer price pressure.

Key data

• Lithium-ion battery consumption tax rate2% from 2026-09-01; 4% from 2027-09-01Applies to lithium batteries produced and sold domestically in China.
• Tax-exempt scopeSodium-ion batteries and solid-state batteries exempt through the end of 2028Exported batteries and batteries produced and sold overseas are also not directly affected by the new consumption tax.
• 2026 most pessimistic net profit impactApproximately 3%-16%Assumes battery manufacturers fully absorb the tax burden, with net margins declining by approximately 0.4-0.6 percentage points.
• 2027 most pessimistic net profit impactApproximately 10%-50%The impact expands after the tax rate rises to 4%, with net margins declining by approximately 1.5-2.5 percentage points.
• EV end-market price impactApproximately 0.5%-1% of MSRPApproximately Rmb500 per vehicle for entry-level LFP models, Rmb1,000-1,500 per vehicle for mainstream LFP models, and Rmb2,000 per vehicle for premium NCM models.
• ESS project impactIRR declines by approximately 0.5-1 percentage pointsBased on J.P. Morgan's estimate under the full pass-through scenario.
• Recent battery price changesEV batteries up approximately 9%-13% from the October 2025 low; ESS batteries up approximately 25% cumulatively from July 2025The price increases primarily reflect higher upstream material costs, particularly lithium prices, tight capacity, and strong demand.

Impact & implications

In the short term, the policy is not a devastating blow because it was already anticipated by the market and the 2026 impact is relatively modest; in the medium term, profitability pressure will become more pronounced after the tax rate increases, particularly for battery manufacturers with high domestic sales exposure, low margins, and weak pricing power. If the tax burden can be partially passed through, leading companies will suffer limited damage; if it cannot, profit divergence across the industry will widen. The policy may also work alongside tighter capacity approvals and lower export tax rebates to strengthen supply-side constraints and drive industry consolidation.

Risks

• Battery manufacturers may be unable to effectively pass the consumption tax on to EV OEMs or ESS customers.
• Net profit and net margin pressure may increase significantly after the tax rate rises to 4% in 2027.
• Weak downstream EV sales and cost inflation may limit the scope for price increases.
• Small and mid-sized battery manufacturers with high domestic revenue exposure, low margins, and weak pricing power may face greater pressure.
• If upstream materials such as lithium continue to rise in price, the consumption tax may compound cost inflation pressure.

What to watch

• Battery manufacturers' pricing strategies and progress on contract renegotiations after the consumption tax takes effect in September 2026.
• How the tax burden is allocated among battery manufacturers, EV OEMs, and ESS customers around the time the tax rate rises to 4% in September 2027.
• Changes in the domestic and overseas revenue mix and net margin trends of CATL, CALB, EVE Energy, and Gotion High-Tech.
• Commercialization progress of sodium-ion and solid-state batteries during the tax-exemption period.
• The combined impact of China's battery industry supply-side reform, capacity approvals, export tax rebates, and consumption tax policies.
