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: electronics. Company profile →
Corning Incorporated (NYSE: GLW) is a US materials-science company built around glass, ceramics, and optical-physics manufacturing. Its core businesses are display glass (LCD/OLED substrates), optical communications (fiber and cable for telecom/datacenter networks), specialty materials (Gorilla Glass cover glass, semiconductor-fab optics), environmental technologies (ceramic substrates for vehicle emissions control), and life sciences (laboratory and pharma-packaging glassware). It also holds an 80.
5% stake in Hemlock Semiconductor, a major US producer of polysilicon for the semiconductor and solar industries.
Verbatim from the dossier's “What they do” section — sources on the company profile.
This is where Corning Incorporated 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.
Silicon — *bulk input*. Silica (SiO2) is the base network-former in every glass product Corning makes (display glass, Gorilla Glass, optical fiber cladding, lab glassware).
Tin — *trace additive*. Modern alkali-free display glass (e.
Germanium — *trace additive*. Corning pioneered germanium-dioxide- doped silica as the low-loss optical-fiber core dopant in 1972 (following an earlier titanium-doped design), and germania doping of the fiber core remains standard for the optical-fiber business today.
Boron — *structural component*. Corning's alkali-free and borosilicate glass formulations (used across display substrates, Gorilla Glass, and Valor Glass pharmaceutical packaging) carry boron oxide as a network-forming component, typically in the low-teens weight-percent range — enough to matter to the melt chemistry and supply, not a trace do…
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.

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.

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 changes the form of what TZ 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 TZ-origin raw feed becomes processed-only; the route is a value-added purchase or a TZ processing partner, not a supplier switch.
silicon — you sit on the supply side: a measure tightening others' supply pushes buyers toward you, so your move is positioning, not substitution (chokepoint page).

⚠ Extraterritorial measure — switching supplier origin may not exit its scope.
China State Council enacts unified Regulations on Export Control of Dual-Use Items 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. For the 1 it produces, the same restriction supports pricing — a tailwind. Scores are footprint-adjusted and buyer-relative (0–100, higher = more exposed).
Its sector (electronics) has no downstream edges in our supply-chain adjacency graph — no downstream signal in the register.
For each bought material: the ex-controller producers a procurement team can actually reach, from the alternatives map (derived 2026-10-05), 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.
This company sits on the supply side of silicon. Restrictions by 🇨🇳 CN push buyers toward ex-CN producers — the strategy is to be visible where those buyers look: the silicon chokepoint page and the watchlist.

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.
