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: chemicals. Company profile →
Tosoh Corporation (TSE: 4042) is a Japanese integrated chemical manufacturer organised around four core areas — Basic Chemicals, Petrochemicals, Specialty Materials and Engineering — with FY2026 net sales of about US$6.8 billion and roughly 14,850 employees across some 104 group companies. Its two Japanese manufacturing complexes are the Nanyo Complex in Shunan, Yamaguchi (about 3 million m², the largest single chemical manufacturing complex in Japan, with up to 776 MW of in-house power generation) and the Yokkaichi Complex in Mie.
The commercially distinctive part of the group for critical-materials purposes is its Advanced Materials Division, whose published product list runs to yttria-stabilized zirconia powders and compounds, zirconia grinding media and fine beads, electrolytic manganese dioxide, synthetic and high-silica zeolites, silica glass raw materials, fabricated and machined quartzware, and sputtering targets for thin-film deposition. Europe-facing manufacturing includes Tosoh Hellas Single Member S.A. in Thessaloniki, Greece and Tosoh Quartz, Inc.'s manufacturing facility in Durham, United Kingdom.
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 🇯🇵 Japan, 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.
Manganese — *bulk input*, and the anchor exposure of this dossier. Tosoh describes itself as "one of the world's largest producers and leading suppliers of electrolytic manganese dioxide (EMD), a key material for high-performance alkaline batteries.
Lithium — *trace additive*, and deliberately listed low. Tosoh's Organic Chemicals Division product list names "Lithium p-styrene sulfonate (Spinomar™ LiSS)", a specialty functional monomer.
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 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.
Brazil supplies 4.1% of world lithium mining — that is the stake if its terms tighten.
Secondary — only if you need to avoid Brazil entirely: lithium supply outside BR is 🇦🇺 AU 34%, 🇨🇳 CN 22%, 🇨🇱 CL 20% (shares renormalised after removing BR).
manganese — you sit on the supply side: a measure tightening others' supply pushes buyers toward you, so your move is positioning, not substitution (chokepoint page).

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 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 1 it produces, the same restriction supports pricing — a tailwind. Scores are footprint-adjusted and buyer-relative (0–100, higher = more exposed).
Its customers sit in manufacturing, petrochemicals. 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 2026-10-05), 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 manganese. Restrictions by 🇨🇳 CN push buyers toward ex-CN producers — the strategy is to be visible where those buyers look: the manganese 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.
