Why Congo’s cobalt is at the centre of a global trade war

The Democratic Republic of Congo’s cobalt has moved from a relatively obscure commodity to a strategic pressure point in the global economy. A metal once valued mainly in tool steel, rechargeable batteries and aerospace superalloys now sits at the centre of competition between mining capitals, battery manufacturers and governments seeking supply beyond a single dominant industrial chain. The stakes are financial, but they are also political: Congo’s resource wealth can support development, and control of its export routes can affect bargaining power far beyond its borders.

Concentration creates leverage. Congo supplies around 70 per cent or more of mined cobalt, depending on the year and estimate, and accounts for an exceptionally large share of identified reserves. Yet the geography of the chain is more complicated than that headline suggests. Ore is commonly shipped as a by-product of copper mining, refined in China or elsewhere, and then incorporated into cathode materials and cells sold to vehicle and electronics makers. Congo controls a critical upstream bottleneck; other countries control many of the stages where the metal acquires its largest value.

What is unfolding is a trade war in the broad sense: governments and firms are using export controls, investment restrictions, subsidies, procurement rules and environmental standards to tilt access to strategic minerals. Some measures are open, while others work through contract renegotiations or the quiet movement of processing capacity. This contest can lift prices in the short term, but it may also divide suppliers into competing blocs, increase compliance costs and leave smaller producers unable to satisfy demanding traceability rules.

These choices have consequences well beyond boardrooms. Mining can provide wages, infrastructure and public revenue, while poorly regulated extraction can bring dangerous work, pollution and displacement. For Australia, the issue is remote from everyday life but connected to imported batteries, vehicle prices, industrial investment and the country’s role in supplying a wider Asia-Pacific market. Understanding how this small, concentrated commodity market works is essential to judging which claims about the trade war are credible.

A market concentrated in one country

Copper and cobalt occur together in mineral deposits across Congo’s copper belt, particularly in the southeast. The mines sit inland, often hundreds of kilometres from the Atlantic, and depend on roads, rail, barges or combinations of all three to reach world markets. Cobalt’s geology also limits how quickly supply can respond. Because much of it is recovered while mining copper, a strong copper market can bring more cobalt onto the market, but a cobalt shortage alone does not make producers switch easily to a richer cobalt-only mine.

The figures around this dependence are often repeated without their context. Congo is the dominant source of primary supply, but the world cobalt market is small enough that stock levels, temporary outages and policy announcements can move prices sharply. Producers also sell different forms of cobalt, from hydroxide and metal to intermediates, and buyers price those forms differently. When one country holds so much of the origin and another holds so much refining capacity, neither side can replace the other without delays that may last years.

Transport and security add another layer. Civil conflict in eastern Congo, congestion around key corridors and weak state control at borders can interrupt legal shipments or encourage smuggling. Security pressures elsewhere in Africa can feed into insurance premiums, staffing decisions and freight rates. A regional conflict assessment provides background on those wider risks. They matter because a mining concession has little value when the route to a port is unsafe, costly or politically uncertain.

China sits at the centre of the cobalt chain

Chinese-backed companies are central to Congo’s mining system. Major operations such as Tenke Fungurume and Kisanfu produce copper with substantial cobalt output, and Chinese firms also hold stakes across other deposits, trading businesses and local services. Their position was built through a long sequence of commercial and diplomatic agreements with Kinshasa. Chinese banks, contractors and equipment suppliers helped connect remote mines to power and transport networks, making China both a source of capital and a powerful customer for the resulting metals.

That relationship complicates the idea of a simple contest between Beijing and Brussels or Washington. Congo’s government has relied on Chinese capital and technical capacity while also seeking more revenue, local employment and processing at home. Chinese refiners can turn exported hydroxide into higher-value products, and some investment proposals involve building that processing inside Congo. The attraction is obvious: if a producer can obtain finance, machinery and buyers from one partner while demanding a larger domestic share, its bargaining position improves.

The strategic value of cobalt extends beyond electric cars. It helps make batteries more durable, remains important in jet-engine and gas-turbine alloys, and is used in specialist industrial equipment. Manufacturers have developed alternatives, including nickel-rich chemistries and lithium iron phosphate batteries that use no cobalt, yet cobalt-intensive designs still matter for energy density and weight. The result is a market in which mining companies, refiners, chemical plants, vehicle makers and governments are all trying to secure their preferred link in the chain.

Kinshasa has learned to use export control

Kinshasa tested that leverage in February 2025, when it announced an immediate pause in cobalt exports while authorities worked out how to control volumes and raise the metal’s value. The episode was often described as a boycott or a rupture with China, but the government’s stated concerns were broader. Falling cobalt prices, unwanted stockpiles and frustration over the limited processing done in Congo all shaped the policy. Negotiations with mining companies followed, with the government arguing that a coordinated quota regime would prevent the lowest-cost operators from taking all the gains.

Export control can be useful when a state has enough administrative reach to enforce it. Congo’s record is mixed. Tax collection, border management and environmental oversight are uneven, while formal export routes can be bypassed through neighbouring states and informal trading. That leakage weakens both state revenue and supply-chain traceability. At the same time, sudden controls unsettle customers and can transfer bargaining power to refiners holding stockpiles. The policy therefore carries a domestic audience as well as an international one: it must reassure communities that mineral wealth is producing visible benefits.

International buyers are demanding proof that material was mined lawfully and transported securely. The European Union’s battery rules and conflict-minerals initiatives, for example, require companies to trace cobalt and other inputs more carefully. Artisanal mining is not a marginal part of the DRC system; it supplies livelihoods while also exposing workers, including children, to unstable shafts, exploitation and contaminated water. Western industrial mines face serious safety and pollution questions too. Verification remains costly, and small traders can disappear into complex supply networks long before a final smelter sees the metal.

Governments are building competing supply blocs

The response from consuming economies has been to reduce dependence through policy rather than wait for prices to do the job. The United States has tied incentives for electric vehicles to qualifying critical minerals and restrictions on material linked to foreign entities of concern. The European Union is combining battery regulation, carbon-footprint requirements and due-diligence rules. Japan, South Korea and India are pursuing their own agreements and industrial subsidies. Each ruleset creates a preferred geography of supply, and a mine accepted in one system may still face additional checks or exclusions in another.

Industry is responding on several fronts. African producers are negotiating domestic refining, while Indonesia, which built a major nickel-processing industry after imposing its own mining restrictions, is trying to attract cobalt investment. Recycling can return cobalt from old batteries and electronics, although collection systems, chemistry changes and low material prices limit the scale. Designers are also reducing cobalt where performance allows. None of these options is a near-term substitute for Congo at current volumes, but together they change how urgently buyers need new African supply.

The pattern is not unique to minerals. The same contest over who owns a route, who earns freight income and who bears political risk is visible in the Niger–Benin oil corridor, where a pipeline links landlocked Niger’s oil fields to Benin’s coast. Mineral corridors have similar vulnerabilities: a border dispute, sanctions regime or security emergency can interrupt a commodity that was secure yesterday. Shipping by sea does not remove those risks, because mines still need roads, railways, ports and insurance before cargo reaches an ocean vessel.

Australia has a stake without a cobalt industry

Australia’s relationship with this market is mostly that of a potential customer, investor and diplomatic partner rather than a producer. Cobalt appears on the national critical minerals list, yet Australia has no large commercial cobalt mine and depends on imported refined material for specialised industrial and battery uses. Government agencies and listed explorers continue to study deposits and processing options, while Canberra has built critical-minerals partnerships with the United States, Japan, India and South Korea. Those relationships give Australian companies access to capital and technology, but they also place the country inside the same geopolitical competition.

Local realities make the issue more immediate than a distant commodity dispute might suggest. Battery vehicles remain a minority of new-car sales, but uptake is growing in Sydney, Melbourne and Brisbane, where charging networks and state climate policies are changing what buyers expect. Australia imports many electronic goods and machinery containing cobalt, so freight shocks or higher prices can reach shelves and factories. At ports used to move metal concentrates and refined metals, including Melbourne, Port Kembla and Brisbane, origin documents and commodity classifications become commercially important as customers verify supply chains.

Customs administration adds another layer. Australian Border Force data and the national tariff classifications applied to imported cobalt compounds and metal products help authorities and companies follow shipments from entry to end use. That paperwork is not glamorous, but it can expose whether material came through a sanctioned route, whether preferential treatment has been claimed incorrectly, or whether a refinery is supplying a battery plant in Melbourne or an electronics distributor in Sydney. For Australian firms trading under stricter due-diligence regimes, traceability may become as valuable as the shipment itself.

Australia cannot negotiate every mining or refinery project abroad, but it has capabilities in mining services, metallurgical research, project finance, battery engineering and e-waste collection. Perth’s exploration sector and South Australian laboratories are part of a wider technical network that can support responsible development in the Congo. The more durable contribution may be to help turn traceability from a paperwork exercise into a credible local system: secure work, verified origin, environmental safeguards and a visible share of revenue returning to mining communities. Australian consumers would benefit from a more resilient battery supply, while local producers could gain access to one of the world’s largest cobalt sources.

Kinshasa has discovered that concentration can produce leverage, while China, the United States, Europe and Asian manufacturers have discovered that dependence can be expensive. The next phase will be decided by whether export rules become transparent enough for trade to continue, whether African states can capture more processing value, and whether buyers accept labour and environmental safeguards that miners can actually meet. Each choice will affect prices today and the distribution of power in the battery industry for years.
