TANIOBIS (formerly H.C. Starck Tantalum & Niobium, Goslar, since 1951) "converts metal ores and secondary materials into high-performance tantalum and niobium-based powders".
It describes itself as one of the world's leading suppliers of tantalum and niobium powders for capacitors, semiconducting materials and SAW devices. The product range covers capacitor powders, metal powders (including AMtrinsic® powders for 3D printing), tantalum and niobium oxides, niobates, oxalates, chlorides and nickel-niobium. The company also lists tungstates. Sites: the Goslar headquarters, TANIOBIS Smelting GmbH & Co. KG in Laufenburg (Baden), TANIOBIS Co., Ltd. at Map Ta Phut Industrial Estate (Rayong, Thailand), and TANIOBIS Japan. It has been owned by JX Metals (now JX Advanced Metals Corporation) since July 2018.
Verbatim from the dossier's “What they do” section — sources on the company profile.
No production footprint is recorded in its dossier yet — its HQ country is 🇩🇪 Germany, a registration fact, not a production or sales claim. We say so rather than guess.
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.
Niobium — producer, bulk product. Niobium powders, oxides, niobates and nickel-niobium. Primary niobium supply is highly concentrated in Brazil.
Tantalum — producer, bulk input and core product. Ta ore concentrate, tin-smelting slags (it developed the slag-extraction route at Laufenburg) and secondary material are processed into capacitor-grade powder and oxides. Feedstock is sourced globally, for example all of AMG's Mibra (Brazil) pre-concentrate since December 2022.
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.

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.

This changes the form of what Brazil exports, not whether you can buy: raw/unprocessed exports are restricted while domestically processed material stays available — that is the measure's own mechanism. Your Brazil-origin raw feed becomes processed-only; the route is a value-added purchase or a Brazil processing partner, not a supplier switch.

This is a reporting / disclosure obligation — it does not prohibit importing from anywhere, so there is no supplier to switch and we list none. What you must do is what the measure's own text above describes: map the supply chain it covers, run the audit, and file. Its text states no filing deadline — we don't invent one.
Mapping your supply chain is exactly the work this obligation requires — your MacroLens exposure report is that map's starting point.

For a material it buys, a restriction tightens supply and raises input cost — a headwind. For the 2 it produces, the same restriction supports pricing — a tailwind. Scores are footprint-adjusted and buyer-relative (0–100, higher = more exposed).

A measure supporting those sectors supports demand for this company's products; one restricting them puts that demand at risk.

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.
