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: mining metals. Company profile →
China Steel Corporation (TWSE: 2002) is Taiwan's largest steelmaker, founded in December 1971 and built around the integrated works at Kaohsiung, with annual crude steel capacity of about 10 million tonnes. Its stated main products are steel plates, bars, wire rods, hot-rolled and cold-rolled coils, electrogalvanized coils, electrical steel coils and hot-dip galvanized steel coils. It operates the only continuous galvanizing line in Taiwan producing both Zn-coated (GI) and Zn-Fe coated (GA) coil.
CSC is a recurring named respondent in US antidumping/countervailing reviews on corrosion-resistant steel from Taiwan, which is what put it in this register.
Verbatim from the dossier's “What they do” section — sources on the company profile.
This is where China Steel Corporation 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.
In its verified exposure list, but the dossier carries no product-level note for it yet — we make no product claim until it does.
Silicon — alloying addition, low-single-digit percent by mass. Electrical steel is the silicon-bearing grade (CSC lists "electrical steel coils" as a main product); silicon is added to raise electrical resistivity for motor and transformer cores. A structural alloying component of that one product line rather than a bulk input to the mill as a whole.
Zinc — coating input, bulk at the coating layer. Two of the named product families (electrogalvanized coils, hot-dip galvanized coils) are zinc-coated, and the galvanizing line is described as producing Zn-coated and Zn-Fe coated coil. Coated coil is also precisely the export line most exposed to the US trade remedies CSC answers to, so the zinc input and the trade exposure sit on the…
Also listed in its dossier but not platform-scored: iron ore — no supply-risk series is tracked for it here.
The dossier also records the materials it investigated and rejected — the list above is narrowed deliberately, not cherry-picked. Its own words:
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.

Gabon (CTRI transitional government, President Oligui Nguema) announced at Africa Forward Summit in Nairobi (May 2026) its intention to subscribe to Eramet SA's €500M capital increase, giving the Gabonese state direct equity in the French-listed parent of COMILOG (its primary manganese mining subsidiary in Moanda). Gabon already holds 29% of COMILOG; a stake in Eramet SA itself would give Gabon leverage over the global operations of the parent group (smelting, nickel, lithium, manganese across France, Norway, Senegal, and Indonesia) and a seat at the Eramet Board. Eramet AGM (May 27, 2026) approved the capital raise resolution. Capital raise planned for H2 2026. Distinct from: filed 2025-05-30-gabon-raw-manganese-export-ban-2029 (the export ban forcing value-addition); filed 2024-07-02-gabon-decret-0276-regimes-des-substances-souveraines (35% state free-carry in new mines) — this is an equity purchase in the parent company, not a free-carry in a Gabonese concession; new vector of state resource-control

This changes the form of what GA 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 GA-origin raw feed becomes processed-only; the route is a value-added purchase or a GA processing partner, not a supplier switch.

The same Finance Bill 2026/27 already tabled (Parliament-passed 23 June 2026, effective 1 July 2026) inserts a NEW export levy of "10% of the FOB value of the cargo OR TZS 200 per kilogram, whichever is higher" on exports of quartz minerals (HS 25. 06) and feldspar (HS 2529. 10. 00) via amendment to the Export Tax Act, Cap. 196 — a distinct beneficiation-forcing EXPORT-TAX instrument that pushes raw quartz/feldspar exporters toward in-country value-addition. 196), and neither existing entry mentions it; (2) material-relevant — quartz HS 25. 06 covers high-purity/silica quartz feeding the silicon→semiconductor/solar value chain, so a Tanzanian export tax re-prices a raw-silica supply node; the same "rocks to riches" beneficiation logic Tanzania applies elsewhere; (3) part of the wider African raw-mineral-export-tax wave (cf.

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. Scores are footprint-adjusted and buyer-relative (0–100, higher = more exposed).
Its customers sit in ev batteries, permanent magnets, ev motors, wind turbines, defence… — read via the graph's critical minerals node, the nearest equivalent of its sector. A measure supporting those sectors supports demand for this company's products; one restricting them puts that demand at risk. The sign shown is the mechanical read — click through to judge whether a measure protects or constrains the customer.
For each bought material: the ex-controller producers a procurement team can actually reach, from the alternatives map (derived 2026-10-07), viability-gated — each name carries its deployment status (with the verbatim dossier phrase it rests on), a capture check against the measure being escaped, and any contracted-capacity evidence. Deployable-now names sort first; a developer with zero tonnes is shown demoted, never dressed up as a switch you can make today. Tradability is inherited from the listing layer, never guessed.

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.
