China Imposes Battery Tariffs and Freezes Factory Approvals in the Same Week
New import duties on five battery types take effect this month as Beijing halts new storage plant permits, slowing the EV infrastructure build that has displaced over a million barrels of daily oil demand.
China will impose a 2% import tariff on mercury-free primary batteries, nickel-metal hydride batteries, lithium primary batteries, lithium-ion batteries, and all-vanadium redox flow batteries starting this month, rising to 4% from September 2027, according to documents circulated over the weekend of September 5-6. Photovoltaic cells face the same phased treatment, with a 2% levy from April 2027 climbing to 4% a year later.6
The timing carries weight because Beijing moved on both fronts simultaneously. Chinese financial news outlet Cailianshe reported over the same weekend, drawing on industry sources, that authorities have paused approvals for new battery storage factories while reviewing existing and planned capacity. Tariffs raise the cost of imported batteries; the approval freeze caps how fast domestic manufacturing can replace that supply. Together, the two moves tighten the near-term outlook for battery availability more sharply than either would alone.6
For crude oil markets, the battery sector's importance runs deeper than the equipment trade. In the first half of 2026, China's electric vehicle fleet displaced an estimated 34 million tonnes of oil — roughly 1.35 million barrels per day, which oilprice.com noted exceeds 1% of total global oil consumption. If that displacement rate held for a full year, it would approach 12% of Chinese crude imports.4
That reduction in oil demand has been accumulating against a backdrop dominated by supply disruption. In 2025, nearly 15 million barrels per day of crude transited the Strait of Hormuz, with China and India together receiving 44% of that flow, and an estimated 45-50% of Chinese crude imports moving through that chokepoint.4 The EIA's August 2026 Short-Term Energy Outlook raised its third-quarter Brent forecast to $85 per barrel on the back of continued severe Hormuz constraints. ICE Brent crude front-month was at $96.98 per barrel as of September 8, well above that August projection, reflecting a more persistent supply disruption than the EIA assumed six weeks ago.5
China's response to Hormuz has been to stockpile aggressively. Since early February, its observable oil stocks grew by 110 million barrels to a record 1.2 billion barrels, triple the level seen previously, according to data firm Kayrros in reporting from the Economist in May 2026. Those reserves were 56% full at the time of reporting.2
The battery tariffs and approval freeze cut across that stockpiling strategy in an indirect way. Slower domestic battery manufacturing capacity means slower EV and storage deployment, which in turn slows oil demand displacement. For a country routing an estimated 45-50% of crude imports through a contested strait, every increment of domestic clean energy infrastructure that reduces import dependence carries strategic weight.4
Analyst views on crude diverge. OCBC Group Research lowered its Brent price forecasts through the second quarter of 2027 in early July, pointing to improving Hormuz shipping activity and expectations of abundant global supply. Yet Dubai crude was trading at $98.71 per barrel as of September 8 — above ICE Brent's $96.98 over the same period — a premium that reflects continued Persian Gulf risk rather than the demand-side easing OCBC anticipated.3
Coal has filled some of the gap left by disrupted energy imports. April 2026 saw coal power generation rebound after its 2025 decline, as Hormuz disruptions weighed on crude and gas imports. China imports 500 million tonnes of coal annually to fuel 60% of its power generation, according to Economist reporting. Total power generation rose an estimated 6.6% year-on-year in that period, with weak wind output, subdued solar performance, and nuclear refuelling outages pushing coal-fired generation higher for the fourth consecutive period.1,2
Solar cell production fell 25.6% year-on-year in the same window, partly reflecting weaker domestic installations, and new capacity additions dropped 31% year-on-year in the first quarter against a high prior-year base.1
The factory approval freeze on batteries adds uncertainty to how quickly China can reverse that slowdown. Battery cost and availability determine whether utility-scale storage attached to wind and solar projects gets built on schedule. If approvals remain suspended through year-end, project timelines slip — and coal stays in the dispatch stack longer than Beijing's own clean energy targets allow.
The practical question for crude traders is whether EV-driven oil displacement continues at its first-half 2026 pace, or whether the combined drag of import tariffs and a manufacturing review slows the rollout of the vehicles and infrastructure that made a 1.35 million barrel-per-day displacement figure possible. That figure doesn't appear on any futures screen, but it is already reshaping China's import curve — and anything that interrupts it changes the demand side of a market already stretched by Hormuz.4
