What they make, where they produce, the materials that matter — then what is coming, what it would do to the business, and the moves available. Sector: industrial. Company profile →
Tiamat is a 2017 CNRS/RS2E-network spin-off headquartered in Amiens, France, that designs, industrializes and sells sodium-ion (Na-ion) battery cells for high-power mobility and stationary-storage applications. Its Gen1 cylindrical cell delivers 90-110 Wh/kg with very high discharge/charge rates (up to 60C) and sub-10-minute fast charging; Gen2 targets ~140-160 Wh/kg. The company's core pitch is a battery chemistry that is explicitly lithium-free and cobalt-free, positioned as a supply-chain hedge against Li-ion raw-material risk rather than a like-for-like energy-density competitor.
Verbatim from the dossier's “What they do” section — sources on the company profile.
This is where Tiamat produces — approximate output shares from its dossier — not where it sells. Sales geography is not yet in our corpus for any company, so we cannot compute exposure to measures that bite on where products ship: an extraterritorial re-export rule follows the shipment and its material content, not the factory. Where such a measure touches its materials, the policy sections below flag it — but its sales-side incidence is not computable yet, and we say so rather than substitute the production map for it.
Of everything in its products, we track the critical inputs — the materials whose supply is concentrated in few countries, policy-exposed, or hard to substitute — because those are the ones a single measure can move. Each carries its role in the product, quoted from the dossier's own exposure note.
Vanadium — the Gen1/Gen2 cathode is a vanadium fluorophosphate, Na3V2(PO4)2F3 (NVPF); vanadium is the redox-active transition metal in the cathode lattice and cannot be substituted without changing the cell chemistry. Vanadium supply is concentrated in China, Russia and South Africa, and is subject to steel-sector demand competition and periodic…
Phosphate — the same NVPF cathode is a polyanionic phosphate framework; phosphate (PO4) is a structural component of every cell Tiamat makes, not an incidental input.
Aluminium — sodium (unlike lithium) does not alloy with aluminium at low potential, so Tiamat's negative-electrode current collector is aluminium foil rather than copper foil — a deliberate cost and supply-chain design choice the company markets as an advantage over Li-ion, but one that still creates aluminium exposure across the full cell count (…
Scope. The non-critical remainder of the bill of materials — structural steel, polymers, glass and the like — is not tracked here because it is not supply-constrained: this section covers the constrained inputs, which is where policy risk concentrates, not a full bill of materials.
The top 5 are ranked mechanically — what the instrument does (its transmission class: an export ban is not a reporting duty), × how close to law (stage-derived likelihood band, never a probability) × how much of your tracked bill of materials it touches. Each unfolds as a chain: trigger → what it hits → the response the instrument actually calls for. A measure touching a material you produce can be an opportunity, not a threat.

Effective 1 May 2026 China suspended exports of all ordinary industrial sulfuric acid — including the acid co-produced from copper/zinc smelting — with only electronic-grade high-purity acid still exportable under special approval; reporting attributes the measure to a joint Ministry of Commerce (MOFCOM) + General Administration of Customs (GACC) notice, expected to run through end-2026. Sulfuric acid is the indispensable leach/process input for copper hydrometallurgy (SX-EW), phosphate-fertilizer production, and battery-metal (nickel HPAL, lithium) processing, so a China export halt tightens a systemic upstream chokepoint hitting seaborne-acid buyers (Chile/Peru copper, Morocco/India phosphate, Indonesia nickel). This is a DISTINCT instrument from the already-filed 2025-12-12-china-ndrc-phosphate-fertilizer-export-suspension (finished-fertilizer export control) and 2026-03-31-russia-decree-350-sulphur-export-ban-extension (elemental sulphur, different country/product) — it controls the acid itself.

China supplies 44% of world phosphate mining — that share of your supply base is what this measure cuts off.

On 6 August 2026, at a ceremony at the Petit Palais of the Presidency chaired by Djiba Diakité (Minister Chief of Staff, chair of the Simandou 2040 Strategic Committee), Guinea's wholly state-owned Nimba Mining Company (NMC SA) signed its first mining convention, covering bauxite extraction at Tinguilinta and export via the Port of Kamsar — a 690. 20 km² concession in Boké Prefecture, 25-year term, refinery requirement, no tax exemptions. This operationalises NMC, which was created by the 5 August 2025 presidential decree revoking GAC/EGA's bauxite concession (already filed: 2025-08-05-guinea-presidential-decree-gac-nimba-mining-sa) — since start-up NMC has extracted ~5 Mt bauxite, exported ~4 Mt in 2026, and the Mines Ministry projects 8-10 Mt for 2026, 12 Mt 2027, 14 Mt 2028. Executive-signed and in force operationally, but multiple outlets state the convention text still requires National Transition Council ratification before Journal Officiel publication — parked on axis 2 rather than filed as enacted pending that primary text. Guinea = priority-tier chokepoint (bauxite, ~world's top exporter).

President Peter Mutharika signed an executive order (dated 23 Oct 2025, effective 21 Oct 2025, announced at Sanjika Palace during a cabinet swearing-in) prohibiting the export of raw/unprocessed minerals extracted in Malawi — uranium, rare earth elements, niobium, graphite, tantalum, bauxite, coal, limestone, gemstones, heavy mineral sands, vermiculite, phosphate, rutile, gold, diamonds, copper and others — with an exemption for minerals processed/refined/value-added domestically per Malawian mining law. Announced alongside a suspension of new mining-licence issuance and a review of mining laws (2026/27 State of the Nation Address), plus a planned sovereign wealth fund. Stated rationale: local beneficiation, targeting up to USD 500m/yr once the Kasiya rutile/graphite deposit (Lilongwe) and Kangankunde rare-earth project (Balaka, Mkango Resources — Africa's prospective first new REE mine since 2017, targeting late-2026 production) are fully developed. Violators face fines/penalties under Malawian law. MW is currently the THINNEST country in the register (1 prior action) despite this breadth of minerals covered. Export-ban/beneficiation-mandate, same instrument class as Zimbabwe's SI 213/2022 raw-mineral bans and Guinea's 2026 gold-export ban already in the register.

The prohibition covers the raw/unprocessed form; material processed in Malawi stays exportable under the order's own exemption — so a Malawi processing route remains open alongside the alternatives below.
aluminium — Malawi holds no measurable share of world mining production in our table (2025 data), so this measure removes little measurable supply for you today; its weight is as precedent, not as a supply loss.

lib/policy-transmission.ts): an export prohibition in the measure's name/text → supply restriction; a raw/unprocessed-export limit or local-processing mandate → beneficiation (form change, not unavailability); reporting/disclosure/due-diligence language → compliance obligation; tariff/trade-remedy language → import cost; subsidy/fast-track/relaxation language → support; investment-screening/M&A language → investment control. When the text carries no signal we fall back to the action-type default and label the chip inferred; when neither exists the card says so and derives no response — we never assert a class the evidence doesn't support.lib/iptm-material-country-production.ts; mining stage preferred, refining as fallback — the stage and source year are in each figure's hover text). Ex-issuer supply removes the ISSUING country and renormalises the remaining listed shares (so they sum to 100% of what's left) — alternatives to the country making the rule, never a default ex-China list. Where the issuer holds no measurable share, the card says so plainly instead of implying supply loss.lib/alternative-viability.ts): each named alternative carries a deployment status — operating / ramping / restarting / development / unknown — derived from word-boundary signal phrases in its own dossier (“operating since 1896”, “restarting the … mine”, “FID taken”), and the verbatim matched phrase is shown as the basis so the claim is auditable; a dossier with no signal stays unknown, never guessed. Any evidenced production date is quoted verbatim (“first production targeted H2 2029” → “no tonnes before 2029”) — we never synthesize one. A measure whose own text claims extraterritorial / re-export / de-minimis / foreign-direct-product / percentage-of-value scope triggers the origin-switching warning above the list: such a rule follows the material, not the seller, so a foreign-made alternative can still be captured. Same-issuer register actions targeting an alternative's country and material mark it may be captured, with the entries linked. “Capacity partly committed” lines quote the dossier verbatim — we hold no structured free-capacity numbers and never imply a utilisation figure.How MacroLens tracks this for you.
