Assessment of the impact of China's battery consumption tax resumption: CATL is the most resilient, maintain Buy on A/H
Goldman Sachs believes the resumption of the battery consumption tax will accelerate industry share concentration toward leaders. CATL is the most defensive due to its high overseas exposure and strong per-unit profitability, while second- and third-tier players and energy storage projects will face greater impact.
- China will impose a 2% consumption tax on primary lithium batteries and lithium-ion batteries starting September 1, 2026, and raise it to the standard 4% rate starting September 1, 2027.
- Under a 50% tax pass-through scenario, CATL's 2026-2028E earnings downside versus Goldman Sachs' current forecasts is only 1-6%; if there is no pass-through at all, the downside is 2-13%.
- For second- and third-tier makers such as CALB and REPT, estimated 2026-2028E earnings downside is 8-41% under 50% tax pass-through, widening to 15-82% with no pass-through; Gotion faces the risk of turning loss-making.
- On the downstream side, the estimated impact on passenger vehicle end prices is 1-2%, the effect on electric heavy-duty truck economics is limited, and BESS projects are the most sensitive because their return hurdles are tighter.
Report interpretation
Overview
This report assesses the potential impact of the battery product consumption tax policy adjustment announced on July 17, 2026 by China's Ministry of Finance, General Administration of Customs, and State Taxation Administration on battery manufacturers and downstream applications. The policy ends the decade-long consumption tax exemption for mature battery products: starting September 1, 2026, primary lithium batteries and lithium-ion batteries will be subject to a 2% consumption tax, rising to 4% from September 1, 2027; next-generation technologies such as sodium-ion batteries, solid-state batteries, fuel cells, and advanced photovoltaic technologies will remain temporarily exempt from September 1, 2026 to December 31, 2028.
Core views
Goldman Sachs believes this policy change is broadly manageable for industry leaders, but more challenging for battery makers with high domestic sales exposure and lower per-unit profitability, reinforcing the view that market share will continue to concentrate toward leaders. CATL is the most resilient among covered companies due to more than 30% overseas exposure and strong 2025 net profit per unit of Rmb109/kWh; most Tier-2/3 companies have higher earnings sensitivity. If fully passed through downstream, the impact on passenger vehicles and electric heavy-duty trucks is limited, while BESS projects are more vulnerable because IRR and return thresholds are tight.
Analysis framework
Using the application of the consumption tax to domestic sales as the core constraint, the report compares domestic sales exposure, net profit per unit, and tax pass-through capability across companies, and estimates the impact on 2026-2028E earnings, gross margin, net margin, and project returns under simplified scenarios including no tax pass-through, 50% pass-through, and full downstream pass-through.
Methodology notes
No pass-through and 50% pass-through
Two simplified scenarios are used to assess the potential impact on battery companies: the consumption tax cannot be passed through to customers, and 50% of the tax burden can be passed through. Since the consumption tax applies to domestic sales, domestic exposure and profit per unit are the core sensitivity variables.
Impact on end prices and project returns
For passenger vehicles, electric heavy-duty trucks, and BESS projects, the battery consumption tax is assumed to be fully passed through downstream, and the impact on end prices, driver economics, and energy storage project IRRs is assessed respectively.
Growth, Financial Returns, Multiple, Integrated
Goldman Sachs' factor framework uses growth, financial returns, valuation multiples, and integrated percentiles to compare stocks with the market and industry peers, mainly to provide investment context.
Asset mapping & comparison
Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).
- CATL / 300750.SZ / 3750.HKCore beneficiary or most resilient name
- Strengths
- Overseas exposure exceeds 30%, and 2025 net profit per unit is Rmb109/kWh, higher than the combined level of other covered companies; the tax impact is relatively manageable.
- Weaknesses
- Domestic sales will still be affected by the consumption tax, and under a scenario of zero pass-through, 2026-2028E earnings still face 2-13% downside.
- Comparison
- Compared with most Tier-2/3 battery makers, CATL has the lowest earnings sensitivity.
- Risks
- Tax pass-through negotiations fall short of expectations, domestic demand volatility, and changes in policy implementation details.
- Tier-2/3 battery makers including CALB, REPT and GotionRelatively pressured names
- Strengths
- Some companies such as EVE and Zenergy are relatively less affected due to higher per-unit profitability.
- Weaknesses
- They have high domestic exposure and low per-unit profitability, with weaker ability to absorb or pass through the tax burden; Gotion faces the risk of turning loss-making.
- Comparison
- The earnings downside for CALB and REPT is significantly larger than for CATL.
- Risks
- Intensified price competition, customer refusal to accept pass-through, margin compression, and share loss.
- Passenger vehiclesDownstream application
- Strengths
- Under full pass-through, the impact on end prices is only about 1-2%, and higher-end models are relatively better able to absorb the impact.
- Weaknesses
- Economy models are more price-sensitive.
- Comparison
- The impact is lower than for BESS projects.
- Risks
- Elasticity of end demand to small price increases and differences in automakers' pass-through strategies.
- Electric heavy-duty trucksDownstream application
- Strengths
- At current oil prices, short-haul electric heavy-duty trucks generate about Rmb8k more profit per month than fuel heavy-duty trucks, allowing full pass-through tax costs to be recovered in about one month.
- Weaknesses
- Economics still depend on oil prices, electricity prices, and operating scenarios.
- Comparison
- The tax impact is more limited than for BESS.
- Risks
- Falling oil prices, freight rate changes, and insufficient vehicle utilization.
- Battery energy storage system projectsMost sensitive downstream application
- Strengths
- Project demand is supported by the energy transition and energy storage build-out.
- Weaknesses
- Return hurdles are tight; under full pass-through of the 4% tax, the IRR of a 400MWh project falls by 0.3ppt, and projects close to the hurdle may drop below required returns.
- Comparison
- More vulnerable to the tax burden than passenger vehicles and electric heavy-duty trucks.
- Risks
- Lower IRR, project delays, investment returns falling below hurdle rates, and constrained cost pass-through.

Impact & implications
The main investment implication of the tax resumption is differentiated profit pressure across the industry and higher concentration. Leaders with overseas sales, strong per-unit profitability, cost efficiency, and pricing power are better able to absorb or pass through the tax burden; second- and third-tier manufacturers with high domestic exposure and low margins may face larger earnings downgrades or even the risk of losses. In the near term, the market may see demand brought forward ahead of implementation as expectations of tax resumption build.
Risks
- Final tax pass-through arrangements will depend on negotiations between companies and customers, and may differ from the report's simplified scenarios.
- Companies with high domestic sales exposure and low per-unit profitability will find it harder to absorb or pass through the consumption tax.
- BESS project returns may fall below investment hurdles because of the higher tax burden.
- Demand pull-forward before policy implementation may disrupt short-term order and inventory rhythms.
- Management commentary during the second-quarter earnings season on the policy impact may change market expectations.
What to watch
- Whether battery demand is brought forward before the 2% tax rate takes effect on September 1, 2026.
- Companies' pass-through ability and pricing strategies after the tax rate rises to 4% on September 1, 2027.
- Management comments from CATL, CALB, REPT, Gotion, EVE, Zenergy and others during 2Q26 earnings calls.
- Changes in BESS project bidding prices, IRR hurdles, and project start cadence.
- Whether the exemption policy for next-generation battery technologies will spur investment in sodium-ion batteries, solid-state batteries, fuel cells, and advanced photovoltaic technologies.
