CATL Halts Jianxiawo Again After Permit Revoked

CATL has returned its Jianxiawo mine, China's largest lithium operation by capacity, to care and maintenance after regulators revoked its environmental approval, prompting Benchmark Mineral Intelligence to cut its 2026 output forecast for the site to 32,000 tons of lithium carbonate equivalent from 62,500 tons.

Contemporary Amperex Technology Co. (SZSE:300750, HKEX:3750), the world's largest battery maker, has put its Jianxiawo lithium mine back on care and maintenance after Chinese regulators revoked the site's environmental approval. The stoppage leaves China's biggest lithium operation by nameplate capacity idle with no fixed restart date, because the company must now go back through the environmental impact assessment process from the beginning.

The sequence, as described in a report from Benchmark Mineral Intelligence and relayed by INN Battery Metals, is unusually specific. CATL obtained a safety production permit for the mine on June 29, 2026. Satellite imagery reviewed by BMI showed activity picking up at the site shortly afterwards. But the restart went ahead without resolving an outstanding dispute over the mine's tailings pond — the impoundment where waste rock and process water are stored — and that omission drew more than 70 formal complaints. Authorities stopped the operation in the first week of August, and the environmental approval was pulled.

A forecast cut of roughly half

BMI's response was to take a knife to its production model. The price reporting agency now expects Jianxiawo to produce 32,000 tons of lithium carbonate equivalent in 2026, down from an initial forecast of 62,500 tons. That is a reduction of 30,500 tons, or close to half the earlier number — arithmetic on the two published figures, and illustrative of the scale rather than a separately reported estimate.

Set that against the mine's nameplate capacity, which approaches 150,000 tons. On BMI's revised numbers, Jianxiawo would run at roughly a fifth of its design rate this year, again a figure derived from the two disclosed totals. For an asset that is the largest of its kind in China, that is close to dormancy.

The agency left its 2027 forecast broadly intact at about 99,000 tons, which implies it still expects the mine to come back and run hard. But BMI attached a warning to that view: the environmental review could stretch into next year. If it does, the 2027 number becomes a ceiling rather than a base case, and the timing risk shifts from one calendar year into two.

Why a single mine moves the lithium curve

Lithium is a market where a handful of very large assets set the marginal tonne. Jianxiawo sits in that group. Removing tens of thousands of tons of contracted or expected lithium carbonate equivalent from a single year does not simply subtract from a spreadsheet; it forces converters and cathode makers who had penciled in that material to bid for units elsewhere, usually from Australian spodumene concentrate or African hard rock, and usually at a worse price.

The mechanism matters more than the headline tonnage. Chinese lepidolite-sourced lithium of the kind Jianxiawo feeds has spent the past couple of years acting as the swing supply that caps price rallies. When it runs, downstream buyers have a domestic alternative and little reason to chase imported concentrate. When it stops — and stops for regulatory rather than economic reasons, which means it cannot be coaxed back by a higher price — that cap is removed. The practical consequence is a supply balance that tightens without any change in demand.

Two further points make this stoppage different from an ordinary maintenance shutdown:

• The cause is administrative, not commercial. A mine curtailed on weak prices restarts when prices recover. A mine whose environmental approval has been revoked restarts when a regulator says so.
• The process has been reset, not paused. Re-entering the environmental impact assessment is not a formality with a known clock. BMI itself flagged that it may run past the end of this year.

The tailings dispute is the real gating item

The detail that should hold investors' attention is the tailings pond. Safety production permits and environmental approvals are separate instruments in China's mining regime, and the June 29 safety permit evidently did not settle the environmental question. More than 70 formal complaints is a volume that regulators cannot quietly absorb, and it points to a local objection with staying power rather than a paperwork gap.

Tailings management has become the single most scrutinised part of hard-rock lithium permitting worldwide, for reasons that have little to do with lithium and much to do with the consequences of impoundment failures elsewhere in mining. Once a tailings design is contested, the review tends to widen rather than narrow. That is the risk embedded in BMI's caveat about the timeline.

What CATL loses, and what its competitors gain

For CATL, Jianxiawo is a vertical integration play: owning the raw material insulates cell production from spot lithium volatility. With the mine idle, that insulation thins and the company becomes a buyer in the same market its peers are buying in. It is worth being precise about the limits here — the disclosed facts concern the mine, not CATL's cell output, guidance or margins, and no figures on those have been published alongside this stoppage.

The beneficiaries are the producers with permitted, running tonnes. Australian spodumene operators and the West African hard-rock projects that have come online in recent years are the obvious candidates, because they can sell into a market where a large domestic Chinese source has gone missing. Lithium equities have spent an extended stretch discounting oversupply; a permit revocation at the largest Chinese mine is exactly the kind of event that forces that assumption to be re-examined.

What to watch from here

Three markers will tell the story. First, any public step in the environmental impact assessment — a filing, a hearing, a revised tailings plan — which would put a boundary on the timeline BMI declined to give. Second, whether BMI or other agencies revise the roughly 99,000-ton 2027 figure downward, since that is the number carrying the assumption of a clean restart. Third, the behaviour of lithium carbonate spot pricing in China, which is where the missing tonnage will first show up.

The wider market gave no sign of concern on the day. Broad U.S. benchmarks closed higher on Thursday, Sept. 3, 2026: the S&P 500 tracker SPY finished at $773.17, up 1.05%, the Nasdaq 100's QQQ at $717.67, up 1.19%, and the Dow tracker DIA at $536.93, also up 1.19%. Lithium supply shocks rarely register at index level. They register in the cost line of every battery cell made twelve to eighteen months later.

Frequently asked questions

Why did CATL stop production at Jianxiawo?

Chinese regulators revoked the mine's environmental approval after an unresolved dispute over its tailings pond drew more than 70 formal complaints. CATL had secured a safety production permit on June 29, 2026, and satellite imagery showed activity resuming, but authorities halted the operation in the first week of August and required the company to re-enter the environmental impact assessment process.

How much lithium output is being lost in 2026?

Benchmark Mineral Intelligence cut its 2026 forecast for Jianxiawo to 32,000 tons of lithium carbonate equivalent from an initial 62,500 tons. That is a reduction of 30,500 tons, close to half the original projection, and leaves the mine running well below a nameplate capacity that approaches 150,000 tons.

When could the mine restart?

No date has been set. CATL must go back through the environmental impact assessment process, and Benchmark Mineral Intelligence warned that the review could stretch into next year. Because the stoppage is regulatory rather than economic, a higher lithium price cannot bring the tonnage back; only a regulatory clearance can.

Does BMI still expect a full recovery in 2027?

BMI maintained its 2027 production forecast for Jianxiawo at approximately 99,000 tons, which implies it expects the mine to return and run at a high rate. However, the agency attached the caveat that the environmental review may extend into next year, which would put that forecast at risk.

Why does one mine matter to global lithium prices?

Jianxiawo is China's largest lithium operation by capacity, and Chinese lepidolite-sourced supply has acted as swing tonnage that caps price rallies. Removing it forces converters and cathode makers to source elsewhere, typically Australian or African hard rock, tightening the supply balance without any change in demand.

What is a tailings pond and why is it the sticking point?

A tailings pond is the impoundment where a mine stores waste rock and process water. Tailings design and management have become the most heavily scrutinised element of hard-rock lithium permitting globally. Once contested, reviews tend to widen rather than narrow, which is why the timeline for Jianxiawo's clearance is open-ended.
