China's New Rare Earth Playbook: What April and October 2025 Changed

In the span of seven months, China introduced two successive layers of

export controls on rare-earth elements, then partially suspended the

second layer. The cumulative effect rewrote the terms on which every

rare-earth consumer outside China now plans its supply chain.¹²

The April 2025 Turning Point

On 4 April 2025, China's Ministry of Commerce introduced export controls

on seven rare-earth elements — samarium, gadolinium, terbium,

dysprosium, lutetium, scandium and yttrium — together with related

alloys, compounds, metals, oxides and magnets.¹ The measure came as part

of Beijing's response to new U.S. tariffs and was structured to require

exporters to obtain specific licenses rather than operating under the

previous general-export regime.

The market impact was rapid. Export volumes fell sharply in April and

May as the new licensing system ground through its first cases.

Automakers in the United States, Europe and Asia reported difficulty

sourcing permanent magnets, and several plants cut utilisation rates or

paused lines while inventories were rebuilt. The April measures targeted

precisely the heavy rare earths that permanent-magnet producers need

most.²

The geography of the impact was instructive. Japanese and South Korean

fabricators, which had long-standing commercial relationships with

Chinese suppliers, experienced shorter disruptions than U.S. customers —

partly because Beijing issued licenses more readily to buyers in

countries that had not imposed tariffs, and partly because Japanese

refineries in particular had built inventory buffers anticipating

exactly this scenario. European manufacturers sat somewhere in between.

The October Escalation

On 9 October 2025, the Ministry of Commerce expanded the export controls

to cover five additional elements — holmium, erbium, thulium, europium

and ytterbium — as well as processing equipment and technologies. The

new measures were to take effect from 8 November.¹

The October expansion was a qualitative escalation rather than a

quantitative one. The additional elements are used in smaller volumes

than those covered in April, but the inclusion of processing equipment

meant that Chinese refining technology could not easily be exported to

support non-Chinese rare-earth projects elsewhere. That second-order

effect hit the strategic ambitions of countries trying to build

independent supply chains — including Brazil, with its Poços de Caldas

refining hub plans, and the United States, with the MP Materials

Independence facility in Texas.

The November Climb-Down

In early November 2025, China suspended the October controls for one

year. The April measures remained in effect, but Beijing began issuing

general export licenses to selected exporters, which partially restored

the flow.¹ The climb-down came in the context of a framework trade

agreement reached between the U.S. and China in June 2025 and of further

negotiations through the year.

The partial de-escalation did not reverse the structural impact. Buyers

who had been forced to identify alternative sources, build inventory

buffers or accept materially higher prices during April-November were

unlikely to abandon those adjustments simply because some of the Chinese

licenses were reissued. The credibility cost to the pre-April status quo

had already been incurred.

The Price Impact

Prices reacted accordingly. Reuters-aligned market coverage reported

that buyers paid roughly US$10-30 per kilogram more than usual for

permanent magnets produced outside China, and that European rare-earth

prices rose to up to six times the levels seen in China during the

tightest months.¹ Dysprosium traded around US$250 per kilogram, and

terbium above US$1,000 per kilogram.

The price split between Chinese and non-Chinese markets was itself a

signal. In a fully integrated global market, regional price differences

of that magnitude persist only when arbitrage is impossible — that is,

when physical movement of material across borders is blocked by

licensing or logistics. For much of 2025, that condition held.

The Adamas Intelligence magnet-market outlook, in its open-research

commentary during the year, underscored that the fundamental mismatch

between supply and demand for dysprosium and terbium would widen through

the rest of the decade even without further Chinese policy intervention.

The 2025 events simply accelerated a trend that was already structurally

in place. Buyers who had previously treated rare-earth supply as a

commodity problem began treating it as a strategic one.

The Longer-Term Shift

The 2025 sequence has permanently changed the calculation for every

rare-earth consumer. Automakers, defence contractors, wind-turbine

manufacturers and electronics producers outside China now assume that a

portion of their rare-earth supply is politically contingent, and they

build that assumption into contracts, inventory planning and supplier

diversification.

The shift has concrete implications for Brazilian producers. Serra

Verde, Aclara and Meteoric — together with the planned Poços de Caldas

refining hub — offer non-Chinese supply of precisely the kind that

2025's controls made strategically important. The U.S. International

Development Finance Corporation's US$465 million commitment to Serra

Verde was announced against this backdrop and is explicitly aligned with

the strategic logic of diversification.³

For Chinese producers, the 2025 episode was less a triumph than a

warning. The short-term leverage of export controls produced a durable

external response — more capital flowing to non-Chinese projects, more

political urgency in Western governments, more willingness to pay

premiums for non-Chinese supply. The policy worked in one dimension and

backfired in another.

The sequence also reshaped how governments coordinate on

critical-minerals policy. The G7 Critical Minerals Action Plan,

published after the IEA's 2025 Global Critical Minerals Outlook,

explicitly framed its priorities in terms of reducing concentration risk

— with rare earths as the archetypal case. Similar language appears in

the European Critical Raw Materials Act's implementation priorities.

2025 gave the policy language a specific, visible event to point to.

Outlook

The April 2025 controls remain in place, and China continues to issue

licenses case by case. The October 2025 suspension could be reinstated

at short notice. Every month that passes, however, is another month in

which non-Chinese producers ramp, Western refining capacity grows, and

the structural share of Chinese dominance declines at the margin. The

2025 sequence did not end Chinese rare-earth dominance — it accelerated

the multi-year shift away from it. Brazilian producers entering

commercial operation during precisely this window are direct

beneficiaries, and the trajectory of their share within global supply

through 2026-2027 will be one of the most closely watched storylines of
