EU-Mercosur: Europe Looks South for Lithium and Graphite

The EU-Mercosur trade agreement, concluded after more than two decades

of negotiation, treats Brazilian critical-minerals supply as a strategic

economic priority for Europe. Lithium and graphite are named explicitly

in Fastmarkets coverage of the deal, and the commercial flows that will

follow from the agreement could reshape how Brazil's critical-minerals

exports are structured during the 2026-2030 period.¹

The Agreement's Commercial Core

The EU-Mercosur agreement reduces or eliminates tariffs on approximately

90 percent of bilateral trade between the European Union and the four

Mercosur founding members (Brazil, Argentina, Uruguay and Paraguay). For

critical-minerals products, the tariff reductions are particularly

meaningful: several categories of lithium compounds, graphite products,

rare-earth concentrates and specialty alloys see tariff schedules drop

substantially, some to zero.

The agreement was politically negotiated over more than two decades and

was expected to become fully operational through phased implementation

across 2025-2027. Ratification processes in both the European Parliament

and the Mercosur parliaments have been complex, but the direction of

travel has been toward full implementation. For European industrial

buyers and Brazilian upstream producers, the commercial implication is

that the cost structure of Brazilian-origin material landed in Europe

improves meaningfully under the new terms.

Why Lithium Is Central to the Narrative

Lithium appears explicitly in Fastmarkets' coverage of the agreement and

in associated commentary from the European Commission. The logic is

straightforward: European battery-cell manufacturers need lithium,

Brazilian producers have attractive low-cost resources, and the

regulatory framework of the Critical Raw Materials Act rewards

member-state companies that source from partner countries rather than

from Chinese-dominated supply chains.¹

Sigma Lithium's Grota do Cirilo concentrate is the most visible

Brazilian asset in this conversation. European cell manufacturers have

engaged directly with Sigma on multi-year offtake arrangements, and

several have indicated that they would increase their commitment if

Brazilian lithium hydroxide capacity — rather than just concentrate —

becomes available. The trade-agreement tariff treatment applies to both

product categories, but the commercial dynamics shift meaningfully with

processed product.

Additional Brazilian lithium projects at earlier development stages —

CBL's operations, the broader Vale do Jequitinhonha pipeline and

exploration-stage projects in Ceará and other states — stand to benefit

similarly. The structural thesis is that European lithium demand through

2030 cannot be met from European-internal extraction alone, and

Brazilian lithium is positioned as part of the answer.

The geography of delivery also matters. Brazilian Atlantic ports —

Santos, Itaqui, Vitória — are well-positioned for shipments to European

destination ports, and shipping times and costs are materially lower

than for Australian-origin concentrate shipped via the Pacific. Those

logistical advantages compound the tariff benefits of the trade

agreement.

Graphite and the Battery-Anode Question

Graphite is the second commodity that Fastmarkets coverage specifically

highlights in the context of the EU-Mercosur agreement. Brazilian

graphite production at Boa Sorte, Santa Cruz and other mines has been

scaling rapidly, and the European anode-material market — which has

depended on Chinese and, more recently, Mozambique and Madagascar supply

— is actively seeking additional non-Chinese sources.

The European anode strategy under the CRMA envisions a meaningful share

of battery-grade graphite being processed inside the EU by 2030.

Brazilian flake-graphite concentrate, processed into spherical purified

graphite (SPG) either at European facilities or at intermediate Asian

processors and then delivered to European cell manufacturers, is a

natural supply-chain pathway. The trade-agreement tariff treatment

reinforces the commercial attractiveness.

Brazilian operators have also been discussing joint ventures with

European anode-material developers that would see parts of the SPG

processing occur closer to the mine site. Those conversations are at

early stages but reflect the broader strategic logic of moving more of

the value chain into the producer country.

Beyond Lithium and Graphite

Although lithium and graphite receive the most explicit attention, the

agreement's implications extend across the broader Brazilian

critical-minerals portfolio. Niobium, already dominated by CBMM with

large European customer bases, sees further trade-friction reduction.

Rare earths from Serra Verde and the next-wave ionic-clay projects

benefit from the same tariff improvements. Nickel and cobalt from Vale's

Brazilian operations fit into the same battery-supply-chain logic.

The agreement also creates a coordination mechanism for regulatory

alignment on issues such as environmental standards, labour conditions

and sustainability reporting. Those areas — which the CRMA increasingly

builds into its formal requirements — become easier to manage when

Brazilian and European authorities have a trade-agreement-level dialogue

already in place.

Implementation Questions

The agreement's practical impact depends on specific implementation

details that are still being worked through. Tariff-quota allocations

for sensitive product categories, rules-of-origin provisions that

determine whether material qualifies for preferential treatment, and

specific commitments on sustainability standards all affect the

commercial outcome in ways that are not yet fully defined.

There have also been political complications. European agricultural

constituencies have historically opposed aspects of the agreement, and

ratification processes have been slower than proponents hoped. The risk

that implementation stalls o
