China’s grip on the China cobalt supply chain tightens at every stage below ground level: the Democratic Republic of the Congo produces approximately 76% of global mined cobalt, and China controls roughly 80% of global refining capacity — a double concentration that leaves Western battery manufacturers, aerospace suppliers, and defence contractors structurally exposed.
China Cobalt Supply Chain: How the Control Is Structured
The DRC’s dominance in mining is well understood. Less examined is how Chinese industrial strategy converted that upstream reality into downstream control. Chinese firms — led by CMOC, now the world’s largest cobalt producer, and backed by state-aligned financing — secured ownership stakes, streaming agreements, and offtake contracts across Congolese mining assets throughout the 2010s. By the time Western policymakers began treating cobalt as a strategic priority, the midstream was already spoken for.
Refining is where leverage becomes decisive. Converting cobalt ore into battery-grade cobalt sulphate, precursor cathode active material (pCAM), and finished cathode requires processing infrastructure concentrated inside China. The US processing gap is acute: North America has minimal domestic cobalt refining capacity. Europe is marginally better positioned but still heavily dependent on refined material flowing from Chinese facilities.
Glencore, the largest non-Chinese cobalt producer with assets in the DRC and Australia, sells significant volumes into Chinese refinery networks. Diversification at the mine level does not automatically translate into diversification at the point of industrial use.
By-Product Economics Make Supply Inelastic
Cobalt is produced almost entirely as a by-product of copper and nickel mining. This structural reality limits supply responsiveness in ways that pure cobalt economics cannot overcome. When cobalt prices rise, no miner can meaningfully accelerate production by targeting cobalt — output is determined by the primary metal economics of copper and nickel. See the top cobalt producers globally for a breakdown of who controls primary output and where.
This inelasticity makes the supply chain more vulnerable, not less. A sustained demand shock — or a targeted Chinese export restriction — cannot be absorbed by a supply-side response in any near-term timeframe. The DRC’s share of roughly 76% of mined output means any political instability, infrastructure failure, or artisanal mining regulation change in a single country propagates directly into global supply.
Battery Chemistry Shifts Complicate the Demand Picture
The cobalt bull case is real but no longer straightforward. Lithium iron phosphate (LFP) chemistry — cobalt-free by design — has taken substantial market share in passenger EVs, particularly in China. Tesla’s shift toward LFP for standard-range vehicles, replicated by BYD and most Chinese OEMs, structurally reduces cobalt intensity per vehicle in the world’s largest EV market.
High-nickel NMC chemistries — which retain cobalt at lower concentrations — dominate long-range vehicle segments and remain the standard for Western OEM performance applications. Energy storage systems, aerospace superalloys, defence hardware, and speciality chemicals provide demand floors that are largely insulated from battery chemistry substitution. The net picture is cobalt demand growing more slowly than the energy transition narrative implies, concentrated in segments where Chinese supply chain leverage is greatest.

Strategic Implications for Western Buyers
The China critical minerals export controls framework — covering gallium, germanium, antimony, and graphite since 2023 — has not yet targeted cobalt directly. But the architecture for restriction is in place. MOFCOM licensing mechanisms can be extended to cobalt products with limited advance notice, as demonstrated by the speed of the antimony controls introduced in September 2024.
Western procurement strategies are responding, but slowly. The US Inflation Reduction Act incentivises battery supply chains built from non-Chinese sources, driving investment into Australian, Canadian, and Philippine cobalt projects. The EU Critical Raw Materials Act designates cobalt as a strategic raw material with benchmarks requiring 40% domestic processing by 2030 — a target that cannot be met without significant new refining infrastructure that does not currently exist in Europe.
Battery manufacturers sourcing outside Chinese networks pay a significant cost premium and accept volume uncertainty. The economics of Western cobalt supply chains remain disadvantaged relative to established Chinese infrastructure — a gap that will take years, not months, to close.
What to Watch
Three variables will determine how the China cobalt supply chain evolves over the next 24 months: whether MOFCOM extends export licensing to cobalt compounds; whether DRC mining output holds as CMOC and Glencore both operate near peak capacity; and whether LFP penetration in Western markets accelerates faster than currently modelled, compressing demand growth assumptions.
Procurement managers and investors tracking cobalt exposure should treat supply chain concentration — not price volatility — as the primary risk metric. The cobalt explainer covers the metal’s physical properties, applications, and supply chain fundamentals.

How much of global cobalt refining does China control?
China controls approximately 80% of global cobalt refining capacity, converting DRC-mined ore into battery-grade cobalt sulphate, precursor cathode materials, and other refined products. This midstream control gives Beijing structural leverage over downstream battery and EV supply chains regardless of where cobalt is mined.
Why can’t cobalt supply simply increase when prices rise?
Cobalt is produced almost entirely as a by-product of copper and nickel mining, making supply inelastic to cobalt price signals alone. Miners cannot accelerate cobalt output without expanding primary copper or nickel production. This structural constraint limits the Western world’s ability to respond quickly to supply shocks or Chinese export restrictions.
Has China placed export controls on cobalt?
As of mid-2026, China has not applied formal export licensing controls to cobalt or cobalt compounds. However, the MOFCOM licensing framework used for gallium, germanium, antimony, and graphite could be extended to cobalt with limited advance notice. Western buyers should treat this as a latent risk rather than a resolved question.
Are LFP batteries replacing cobalt in EVs?
Lithium iron phosphate (LFP) batteries — which contain no cobalt — have taken significant market share in China and are growing in Western markets for standard-range vehicles. High-nickel NMC chemistries retain cobalt at lower concentrations and dominate long-range segments. Cobalt demand continues to grow overall, but more slowly than earlier EV projections suggested.
Which companies dominate cobalt production outside China?
Glencore (Swiss-listed, DRC and Australian operations) is the largest non-Chinese cobalt producer. CMOC (Chinese state-aligned) is the world’s largest cobalt producer overall following expansion of its DRC assets. Artisanal mining in the DRC, accounting for roughly 15–20% of Congolese output, remains largely outside formal supply chain oversight.
