138,000 Tonnes: Why Chinese Magnet Scale Still Dominates

China produced approximately 138,000 tonnes of sintered

neodymium-iron-boron magnets in 2018, according to the Center for

Strategic and International Studies. The best Western non-Chinese

capacity expected by 2028 is roughly 10,000 tonnes. The arithmetic

describes the gap that the entire post-2025 diversification push is

trying to close.¹

The 138,000 Tonne Benchmark

The CSIS estimate for Chinese NdFeB magnet output in 2018 is the most

widely cited single figure in critical-minerals policy discussions. It

matters not because it is precise — magnet production data is

notoriously difficult to verify — but because it sets the scale of the

benchmark. Whatever MP Materials and Lynas and the next generation of

non-Chinese producers achieve, they are playing against a Chinese

capacity that was already more than an order of magnitude larger nearly

a decade ago.¹

The gap has, if anything, widened since 2018. Chinese NdFeB output

continued to grow through the 2020s as domestic EV and wind-turbine

manufacturing expanded. The exact current figure is not publicly

available at production-line granularity, but independent estimates put

the scale at 200,000 tonnes per year or higher by 2024. Against that

baseline, a Western cumulative capacity of 10,000-15,000 tonnes by 2028

is a beginning, not a solution.

How China Built the Scale

Chinese magnet production did not arrive overnight. It was the product

of three decades of industrial policy, subsidised research and

development, consistent workforce training, and the co-location of

mining, separation, metal-making and magnet-forming in an integrated

geography. The southern provinces of Jiangxi and Ganzhou, in particular,

became effective industrial clusters where the full value chain — from

ionic-clay ore to finished automotive-grade magnets — operated within

relatively compact commercial networks.

The CSIS analysis notes that Chinese dominance extends beyond magnets to

the full refining chain. China is the leading refiner for 19 of 20

important strategic minerals, with an average market share of 70

percent. For sintered permanent magnets specifically, Chinese share has

risen to approximately 94 percent.¹ Those numbers describe a structural

position, not a cyclical one, and they cannot be dislodged quickly by

policy declarations or individual project commitments.

The Other Elements Down the Chain

The magnet step is one of several. Before rare-earth ore becomes a

magnet it passes through mining, initial concentration, chemical

cracking (for bastnaesite or monazite) or leaching (for ionic clay),

solvent extraction to separate individual oxides, reduction to metal,

alloying with iron and boron, powder preparation, pressing, sintering

and finishing. China holds leading global positions in every single

step.

Non-Chinese producers are rebuilding the chain piece by piece. Mining

comes first and is arguably the easiest to replicate — Lynas at Mt Weld,

MP Materials at Mountain Pass, Serra Verde at Pela Ema. Separation is

harder, and only Lynas in Malaysia and a handful of other operations

currently run at commercial scale outside China. Metal-making and

magnet-forming are harder still, which is why MP Materials' Independence

facility and the 10X expansion are so significant: they address the step

of the chain that has been most stubbornly Chinese-dominated.

The alloying and powder-preparation stages carry their own specialised

know-how. Alloy chemistry for automotive-grade magnets must hold

consistent properties across millions of units, and the powder

characteristics that feed into pressing determine the final magnet's

mechanical and magnetic performance. These are not commodity skills;

they are industrial capabilities that Chinese manufacturers have refined

over decades and that Western entrants now have to build from a smaller

base.

What Western Scale Needs to Reach

For Western supply to meaningfully reduce dependence on Chinese magnet

imports, it needs to reach roughly 30-50 percent of Chinese capacity

over the medium term. If Chinese capacity sits at 200,000 tonnes per

year, that implies Western capacity of 60,000-100,000 tonnes per year —

a target materially larger than the current pipeline of announced

projects.

Adamas Intelligence's long-term demand projections help frame the gap.

Total demand for NdFeB magnets is forecast to grow at a compound annual

rate of 9 percent through 2035 and 7.5 percent through 2040.² Even if

Chinese capacity stays flat — which it will not — non-Chinese capacity

needs to expand roughly five- to ten-fold to meet the growing Western

share of demand. That is the scale of the industrial build-out required,

and it cannot be completed in a three-year window regardless of how

aggressive the policy push becomes.

Where Brazil Sits in the Gap

Brazilian rare-earth producers are positioned upstream of the magnet

step. Serra Verde, Aclara and Meteoric supply concentrate and will

eventually supply separated oxides; they do not (currently) produce

metal or magnets. That mid-chain positioning is the right place to be

for Brazilian producers in the near term — competitive separation

capacity is the first capability the industry has to build — but it

means that the 138,000-tonne Chinese magnet benchmark is only indirectly

relevant to Brazilian operators.

Indirectly, however, the benchmark matters a great deal. Brazilian

separation output will eventually need to feed into downstream magnet

production somewhere, and the strategic value of Brazilian rare earths

depends on there being non-Chinese magnet capacity that wants to buy

them. MP Materials, ReElement in Indiana, Neo Performance Materials in

Estonia and a handful of other non-Chinese magnet operations are the

natural customers — and each of them benefits from Brazilian supply that

breaks the last remaining dependencies on Chinese intermediate products.

Outlook

The 138,000-tonne figure is a reminder of scale, not a verdict on

strategy. The Western push to build non-Chinese rare-earth capacity will

not match Chinese scale quickly, and may not match it at all within this

cycle. But the target of meaningful — not dominant — non-Chinese

capacity is achievable, and the combination of MP Materials' 10X

programme, Lynas's integrated build, ReElement's chromatographic

separation, the Brazilian ionic-clay cluster and associated midstream

investments is putting that target within reach by the early 2030s.

China's dominance will not disappear, but it will become more contested

than at any time in the past 20 years — and Brazilian producers,

positioned at the upstream end of an increasingly diversified global

supply chain, will be among the most direct and consistent long-term

beneficiaries of that increasingly contested future across the whole of

the global rare-earth industry over the course of the next full decade.
