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 →
Weir Group plc (LSE: WEIR) is a Glasgow-headquartered engineer of wear-resistant mining and mineral-processing equipment: slurry pumps and hydrocyclones (the Warman/Cavex brands), mill liners and HPGR mills, crushers, screens, valves, and — via the 2018 ESCO Corporation acquisition — ground-engaging tools (excavator/loader teeth, adapters, cutting edges) for surface mining and oil sands. The business is aftermarket/consumables-weighted: wear parts are replaced on a recurring cycle, which is why abrasion-resistant metallurgy sits at the center of Weir's own product engineering rather than at arm's length from it.
Verbatim from the dossier's “What they do” section — sources on the company profile.
This is where Weir Group 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.
Tungsten — coating/insert additive, not bulk. Weir's own "Materials Technology" documentation describes "trials involving the application of tungsten carbide coatings and inserts on pumps in highly abrasive situations." Tungsten carbide is applied at the specific wear-vulnerable spots on a part, not as the part's structural body — a trace-to-moderate hard-facing role, not a mass con…
Chromium — structural component of named wear-part product lines. Weir's own materials page names "Linard® modular abrasion panels with chromium white iron inserts" as a company product. High-chromium white iron is also the standard casting alloy for mill and crusher liners industry-wide, so it plausibly extends across more of Weir's liner range than the one named product — but only the Linard line is…
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.

If enacted, chrome ore export tax and/or quota would disrupt South Africa's ~2. 4 Mt/yr chrome ore export stream (≈45% of global seaborne supply); beneficiation licensing conditions attached to mineral rights allocations would require FTSE/JSE-listed chrome miners (Samancor/Merafe, Assore, Glencore) to build local ferrochrome and stainless-steel capacity before new rights are allocated; PGMs and other minerals may follow chrome as the test-case model, expanding scope to the full South African mining portfolio

This changes the form of what South Africa 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 South Africa-origin raw feed becomes processed-only; the route is a value-added purchase or a South Africa processing partner, not a supplier switch.
South Africa supplies 45% of world chromium mining — that is the stake if its terms tighten.
Secondary — only if you need to avoid South Africa entirely: chromium supply outside ZA is 🇹🇷 TR 36%, 🇰🇿 KZ 28%, 🇮🇳 IN 12% (shares renormalised after removing ZA).

Japan's METI + MOF made an affirmative PRELIMINARY determination in an anti-dumping investigation (initiated 22 Jul 2025 on an application from Nippon Steel, Nippon Yakin Kogyo, NAS Stainless Steel Strip and Nippon Kinzoku) into nickel-added cold-rolled stainless steel coil, sheet and strip originating in the People's Republic of China and the separate customs territory of Taiwan (Penghu, Kinmen, Matsu); Trade Minister Ryosei Akazawa indicated provisional duties of ~45% on Chinese product and ~21% on Taiwanese product, expected to take effect as soon as July 2026. On 19 Jun 2026 METI/MOF EXTENDED the investigation period by four months to 21 Nov 2026 (final determination pending). IPTM relevance: (1) a RARE Japan-issuer trade remedy — JP has ZERO trade-remedy actions on the register and seldom uses AD, so a Japanese AD wall is a notable issuer + instrument-bloc gap; (2) China/Taiwan-target on nickel-added stainless steel, a nickel+chromium chokepoint-adjacent material; re-prices a China/TW->Japan stainless flow into a major downstream manufacturing base; (3) parallels the active 2025-26 Asian steel-AD wave the register is now capturing (Thailand DFT aluminium-extrusions, Indonesia KADI HRC, Malaysia MITI galvanised steel).

A duty raises the cost of the origins the measure names into Japan's market — a cost line on affected flows, not lost availability. Origins outside the measure's named targets are the route around it; the text above names the targets where its source does.

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.

⚠ Extraterritorial measure — switching supplier origin may not exit its scope.
China MOFCOM Announcement No. 1 [2026] — country-specific dual-use export controls on Japan claims reach over foreign-made goods (“extraterritorial”) — the rule follows the material, not the seller, so an alternative outside the issuer can still be captured if its products contain or are made with in-scope inputs. Verify each alternative's feedstock origin before treating it as an exit.
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).

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 2026-10-06), 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.

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.
