Brazil Puts Critical-Mineral Deals Under Review: The CIMCE Screening Matrix

A foreign acquirer or offtake counterparty evaluating a Brazilian critical-minerals asset now faces a question the statute creates but the regulation has not yet operationalized: will the new screening committee clear a transaction, condition it, or stop it? Law 15,506/2026 and Decree 13,118/2026, both published on 2026-09-16, created the National Council for the Industrialization of Critical and Strategic Minerals (CIMCE), whose Executive Committee is designed to review changes of corporate control, foreign stakes, international supply contracts, and transfers of mining rights; the minerals list, the screening thresholds, and the procedures are not yet issued, so no transaction is reviewable until the regulation defines the terms (Primary for the statute; application pending regulation; Planalto, 2026-09-16).

The government has said the first CIMCE meeting should occur within ten days of enactment, putting it near 2026-09-26; the statutory deadline to install and regulate the structure is about 2026-12-15; and the regulation that will define who gets screened does not exist yet (Mixed; CNN Brasil, 2026-09-16; Primary; Law 15,506/2026, Article 45). For a seller, the prospective change is that certainty may now run through a regulatory process with no published thresholds. For a buyer, the diligence file gains a chapter that is designed to cover the offtake contract as well as the equity, once the rules are issued.

What changed

Brazil converted a minerals strategy into a screening framework in one week. The law sanctions PL 2.780/2024 without vetoes and institutes the National Policy on Critical and Strategic Minerals; the decree regulates CIMCE; and Portaria 1.043/2026 named the first non-federal members (Primary; Planalto, 2026-09-16; Demarest, 2026-09-18).

CIMCE has three tiers: a Pleno chaired by the Casa Civil with 13 voting ministers plus state, municipal, private-sector, and higher-education representatives; an Executive Committee coordinated by the Ministry of Development, Industry, Trade and Services (MDIC); and an Executive Secretariat at MDIC with a dedicated investment-screening unit (Primary; Decree 13.118/2026, Articles 4 to 14). The Executive Committee decides concrete cases; per the decree it has seven voting organs, while CNN Brasil reported nine, so use the decree count (Primary; Decree, Articles 9 and 10; contested; CNN Brasil, 2026-09-16). The Ministry of Mines and Energy (MME) must issue an opinion on project and screening cases.

The screening scope has four triggers (Primary; Law 15,506/2026, Article 3, paragraph 2; Decree, Article 10): a change of corporate control, direct or indirect, in a company holding critical or strategic mineral rights; acquisition of a relevant stake or significant influence by a foreign entity, including access to strategic geological information; international supply, offtake, or partnership contracts that may affect economic or geopolitical security; and sale, assignment, or encumbrance of mining rights. Decisions can be non-incidence, approval, conditional approval, or non-approval, with precautionary measures and ex officio proceedings available.

The incentives package is real but not appropriated. The Union may take up to R$2 billion in the critical-minerals guarantee fund (FGAM); the critical-minerals tax-credit program (PFMCE) grants credits of up to 20 percent of eligible processing and transformation expenditure, capped at R$1 billion per year from 2030 to 2034; and companies in the sector must annually apply, from regulation and for six years, at least 0.3 percent of gross operating revenue net of taxes to research, development, and innovation (RD&I) plus 0.2 percent to FGAM quota subscriptions (Primary; Law, Articles 9 to 21; Agencia Brasil, 2026-09-17). The headline “up to R$7 billion” is the sum of the FGAM authorization and the five-year credit ceiling, an Agencia Brasil framing rather than a legal total (Mixed; Agencia Brasil, 2026-09-17).

What the regulation does not yet say is the load-bearing gap. “Relevant stake,” “significant influence,” transaction-value triggers, and the test for economic or geopolitical security risk are all undefined; Demarest calls the absence of objective parameters the main point of attention for corporate and investment operations (Primary for non-definition; Mixed for the advisory judgment; Demarest, 2026-09-18; Trench Rossi Watanabe, 2026-09-21).

Why this matters now

The first meeting is expected by about 2026-09-26; the planned agenda covers the internal rules and the critical minerals list, and the government has said the screening regulation design starts there (Mixed; CNN Brasil, 2026-09-16; Poder360, 2026-09-16; eixos, 2026-09-16). Whether the meeting occurs on that schedule, and whether it approves the list, is unresolved, and the screening trigger and the security test both remain pending, so the meeting is a step, not an operative screen (regulation pending). The sequencing matters for deal teams because the list and the rules are what turn the statute into a screen; until both exist, the regime is authority without procedure (Analytical; Juncture’s reading).

The timing is also political. Brazil’s first-round election is 2026-10-04, with a runoff on 2026-10-25 if required; the 2026-12-15 regulation deadline and the G20 Leaders’ Summit in Miami on 2026-12-14 to 2026-12-15 both fall after the vote (Primary; AS/COA, 2026-07-30; Brasil de Fato, 2026-09-14). The United States has its own posture: a US embassy official said Brazil never answered a Minerals Security Partnership invitation or a February 2026 draft framework and that Washington would “probably have to wait till the election” (Mixed; single-source; The Star, 2026-08-31). MDIC Minister Marcio Elias Rosa and Foreign Minister Mauro Vieira are expected to meet US Trade Representative (USTR) Jamieson Greer around 2026-09-30 to 2026-10-01 in Milwaukee, where minerals may surface (Mixed; Brasil de Fato, 2026-09-14).

The deal that prompted the design is still open on two other tracks: the Administrative Council for Economic Defense (CADE), Brazil’s antitrust authority, opened proceedings in May 2026 on whether the USA Rare Earth acquisition of Serra Verde and its supply agreement constitute a notifiable concentration, and Rede Sustentabilidade asked the Supreme Court in April 2026 to suspend the sale on national security grounds; neither outcome is known (Primary for the filings; outcomes pending; CADE, 2026-05-15; G1, 2026-05-12; Bloomberg via mining.com, 2026-04-25).

The institutional constraint

Screening is a committee of ministries, and ministries move at the speed of their opinions. MDIC coordinates and houses the secretariat, the MME must opine, and the Pleno sets the list and the minimum contribution for FGAM access; the National Mining Agency (ANM) may be invited without a vote (Primary; Decree, Articles 9 and 10). Nothing in the record says how the committee will sequence its reviews with CADE merger control and ANM title approvals, and no retroactive review of closed transactions has been announced; the decree addresses pending administrative processes (Primary; Decree, Article 21; interaction pending).

Two legal provisions widen the surface beyond equity. Article 38 allows private streaming and mining royalty contracts to be registered with ANM with erga omnes effect and specific performance, making them usable as collateral. Whether those structures are themselves screened when no equity changes hands is an interpretation of the international-supply trigger, not a settled reading: Article 3, paragraph 2, item III, read with Article 38, suggests review may apply to qualifying contracts, and the regulation will decide (Primary for registration; screening treatment pending; Law, Article 38; Machado Meyer, 2026-09-18). Article 8 authorizes regulation to set value-addition commitments and information duties covering volume, destination, end buyer, corporate chain, processing degree, and mineral composition; it does not ban exports of unprocessed ore (Primary; Law, Article 8; Courthouse News, 2026-09-16).

The constraint is discretion. In Juncture’s reading, undefined thresholds leave room for similar transactions to be treated differently, and the law gives the committee ex officio powers and precautionary measures (Analytical; Juncture’s reading). That is why industry reaction splits: industry groups and senators have warned that missing criteria create legal uncertainty, and Fiemg called the competences “broad and highly subjective” and criticized domestic-market supply requirements attached to the tax credits (Mixed; O Tempo, 2026-09-02; eixos, 2026-09-02). Ibram welcomed the framework and projects US$21.3 billion in critical-minerals investment for 2026-2030 (Mixed; IBRAM, 2026-08-19; Mayer Brown, 2026-05-22).

What the consensus misses

Four things are being read wrong. First, this is not an export ban and not nationalization; it is a review mechanism over control, stakes, offtake, and titles, with the regulation still to define its bite. Second, the money is not the story: the R$7 billion headline is an authorization and a credit ceiling over 2030-2034, not appropriated capital.

Third, the offtake contract is the tell, and the screening design points at it. Brazilian outlets reported the Serra Verde transaction as a factor behind the council’s creation: eixos reported the government rushed the list and the rules after the US entry into the Serra Verde project, and Capital Digital reported the government weighed submitting the sale to the future council (Mixed; eixos, 2026-09-16; Capital Digital, 2026-08-26). The structure is the template: a 15-year, 100 percent Phase 1 offtake to a special purpose vehicle (SPV) capitalized at US$1.55 billion with US government participation, a US government forward purchase of not less than US$300 million over five years, and US$565 million in financing from the US International Development Finance Corporation (DFC) for the Phase 1 expansion, alongside a Department of War announcement, reported by Engineering and Mining Journal, of US$750 million in offtake support (Primary; single-source for the US$750 million report, named in text; USA Rare Earth, 2026-08-24 and 2026-09-04; E and MJ, 2026-08-26). Avoid the shorthand that the US government owns the mine; the verified instruments are the SPV, the forward purchase, the DFC loan, and the reported offtake support (Primary; no direct equity in Serra Verde located).

Fourth, the comparison set matters, as Juncture’s reading of the three regimes (Analytical). Canada’s Investment Canada Act makes all foreign investments subject to possible national-security review regardless of value, and Ottawa ordered Chinese lithium divestitures in 2022; Australia’s Foreign Investment Review Board (FIRB) screens sensitive sectors including critical minerals regardless of value, and the Treasurer forced divestment of a China-linked stake in Northern Minerals in May 2026; Mexico nationalized lithium and cancelled concessions, with Ganfeng in arbitration at the World Bank’s International Centre for Settlement of Investment Disputes (ICSID) (Primary; Government of Canada, 2022; US State Department, 2025; UTS, 2026-05; UNCTAD, 2022; Mexico Business News, 2026-04-16). Brazil’s framework combines incentives with screening and no expropriation, with thresholds pending (Analytical; Juncture’s reading).

The screening matrix

A Juncture working framework for deal teams; it organizes the statute and decree and is not a legal opinion. The diagnostic question: which of the four triggers could apply to a transaction, and which definition will decide it once the regulation is issued?

Trigger (Law Article 3, paragraph 2; Decree Article 10) What it captures Definition status
Change of corporate control, direct or indirect Acquisitions and reorganizations of companies holding critical or strategic mineral rights Undefined; includes indirect changes via corporate reorganization
Relevant stake or significant influence by a foreign entity, including access to strategic geological information Minority positions and influence without control; access to strategic data Undefined; no percentage, value, or investor-profile test published
International supply, offtake, or partnership contracts affecting economic or geopolitical security Offtakes, streaming, and long-term supply arrangements, including those with no equity transfer Undefined; the security test is unpublished
Sale, assignment, or encumbrance of mining rights or Union-granted titles Title transfers and encumbrances; royalty and streaming registration under Article 38 is defined, but whether those contracts are screened is an interpretation pending regulation Mining-law defined; CIMCE procedure and screening treatment pending

Framework elements. Who decides: the Executive Committee, with the MME opinion and the Pleno above it (Primary; Decree). Exposure map for a deal team: identify which of the four triggers could apply; treat offtake terms as potentially reviewable where the unpublished security test is met; and plan for a regulatory condition in the timetable for qualifying transactions, all subject to the pending rules (Analytical; Juncture’s reading). Failure modes: closing without homologation where required once the rules exist, and treating the incentives package as approval policy when the screening track is separate (Analytical).

Open questions carried by this brief, all of which resolve on the public record:

  • Whether the first CIMCE meeting occurs by about 2026-09-26 and approves the internal rules and the critical minerals list. No convocation had been published as of 2026-09-23.
  • Whether approval of the list alone makes the screening trigger operative for pending transactions. The screening rules and security test are separate and pending.
  • Which minerals make the list. The MME proposes and the Pleno approves, with review every four years.
  • How regulation defines relevant stake and significant influence. This is the load-bearing uncertainty for the deal population.
  • Whether existing offtake contracts are grandfathered, and whether renewals, amendments, and new volumes trigger review.
  • Whether international offtake and streaming structures are screened when no equity changes hands. Article 3, paragraph 2, item III, read with Article 38 suggests review may apply to qualifying contracts.
  • How CIMCE screening interacts with CADE merger control and ANM approvals, and what the penalties and suspensory effects are for closing without homologation.
  • Who administers FGAM, when the Union contributes, and what minimum company contribution CIMCE sets.

How this resolves

The questions below resolve on the public record; no probabilities are assigned.

Open question What would resolve it
Does the regime become operative in 2026? The first meeting approves internal rules and the minerals list, and regulation is issued by about 2026-12-15. The meeting is expected by about 2026-09-26; no convocation had been published as of 2026-09-23.
Do thresholds appear? The regulation defines relevant stake, significant influence, and the security test, with or without value triggers.
Are offtakes screened? CIMCE reviews or homologates a qualifying international supply or offtake contract, or the regulation exempts them.
Do the collateral tracks resolve? CADE concludes its concentration review and the Supreme Court petition is decided. Outcomes are unknown.
Does the election change the design? Post-election regulation narrows, widens, or delays the screening scope relative to the decree. The vote is 2026-10-04; a runoff would be 2026-10-25.

What to watch

  • By about 2026-09-26: the first CIMCE meeting; watch whether internal rules and the minerals list are approved, and whether screening regulation design is formally started (Mixed; CNN Brasil, 2026-09-16).
  • 2026-09-30 to 2026-10-01: the MDIC and foreign ministry meeting with USTR Greer in Milwaukee; watch whether minerals or the screening regime surface in the tariff file (Mixed; Brasil de Fato, 2026-09-14).
  • 2026-10-04 and 2026-10-25: the general election and possible runoff; watch whether and how the vote changes the regulation’s ambition and personnel (Primary; AS/COA, 2026-07-30).
  • By about 2026-12-15: the statutory deadline to install and regulate the CIMCE structure (Primary; Law, Article 45).
  • Ongoing: CADE proceedings on Serra Verde and the Supreme Court petition; ANM Public Consultation 03/2026; FGAM operationalization and the identity of its administrator (Primary; outcomes pending).

Bottom line

Brazil now prices a seat at the table, in principle. The law is not an export ban and the incentives are not appropriated money; the prospective change is that control changes, foreign stakes, international offtake contracts, and mining-title transfers in critical minerals are designed to sit inside a ministerial review whose thresholds are unwritten. In Juncture’s reading (Analytical), the September meeting and the 2026-12-15 regulation will determine how wide that net becomes, and the election will shape who holds it. For acquirers, the neutral implications are a trigger map before signing and a regulatory condition in the timetable for qualifying transactions, both subject to rules that do not yet exist.
