China Introduces a 2% Consumption Tax on Lithium-Ion Batteries From September
On 17 July, China's finance ministry, customs administration and tax authority announced a consumption tax on batteries. Lithium-ion batteries will pay 2% from 1 September 2026, rising to 4% from 1 September 2027, while sodium-ion and solid-state batteries are exempt until the end of 2028.
What was announced
The announcement was issued jointly by the Ministry of Finance, the General Administration of Customs and the State Taxation Administration, according to CnEVPost. Benchmark Minerals describes it as ending eleven years of tax exemption for the lithium-ion battery industry and says the stated aim is to curb overcapacity.
Electrive reports that the tax also covers vanadium redox flow, nickel-based and lithium primary batteries, and that fuel cells share the sodium-ion and solid-state exemption. Rates and dates come from media reports of the notice, and we did not read the original notice itself.
How big is it
CPCA secretary-general Cui Dongshu, writing on 18 July, estimates that at cell prices of about 0.35 to 0.40 yuan per Wh, a 2% tax adds roughly 0.007 to 0.008 yuan per Wh. He notes that batteries a company makes and uses in its own battery production are exempt, and that tax paid on bought batteries can be deducted by the quantity used. His analysis focuses on electric vehicle makers.
What we could not confirm
We could not find how the tax applies to batteries made in China for export, or to energy storage cells specifically, so we cannot say whether it will change the cost of home batteries sold in Europe or the UK. The effect on shelf prices, if any, would also depend on competition, exchange rates and how much of the tax manufacturers pass on.
The exemption for sodium-ion is worth watching, because it nudges investment towards a chemistry that is still small in home storage. Treat any price forecast with caution until the details of the notice are clear.
What to do now
Nothing needs to change if you are planning a purchase. Compare quotes on the system you actually need, using the home battery calculator and Compare For Yourself, and check warranty terms rather than guessing at price moves.
