K+S Aktiengesellschaft (Frankfurt: SDF) is a Kassel, Germany-headquartered mining group and the only potash producer with large-scale production sites on two continents. It operates through three segments — Potash and Magnesium (fertilizers plus technical/industrial/pharma-grade potassium and magnesium compounds), Salt (food-grade, industrial, and de-icing salt), and Complementary Activities. Its resource base is the Werra potash district (Hattorf, Wintershall, Unterbreizbach, Merkers — the world's largest contiguous potash mining area) and the Zielitz mine, both in Germany, plus the Bethune solution mine in Saskatchewan, Canada (K+S Potash Canada, commissioned 2017, ramped to ~2Mt/yr — a "Ramp Up" expansion broke ground September 2025 targeting a doubling to ~4Mt/yr over the next two decades).
K+S exited the Americas salt business (Morton Salt in the US, Windsor Salt in Canada, and SPL in Chile) via a US$3.2bn sale to Stone Canyon Industries in April 2021, refocusing the group on potash, magnesium, and its remaining German/European salt operations. FY2025 group revenue was €3.65bn.

This is where K+S Aktiengesellschaft 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.
Magnesium — bulk co-product, structural to the Potash and Magnesium segment. The Werra Group's carnallite ore stream yields magnesium sulphate and other magnesium compounds sold into technical, industrial, pharmaceutical, and animal-feed applications alongside potash fertilizers; this is a genuine, disclosed product line, not a sector-default guess. *Exposure profile note:* the generic chemicals-sector list (phos…
Potash — bulk input/core commodity, not trace. Potash is the business: K+S is a producer and miner, not a downstream consumer, so its exposure runs through the operating and policy risk of its two mining jurisdictions (German mining/water-protection regulation around the Werra brine-disposal permit history, and Saskatchewan royalty/export policy for Bethune) rather than input-supply…
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.
No upcoming policy in our register currently touches magnesium, potash. The pipeline is re-scanned continuously; this line changes the day that changes.
3 of 9 filed an explicit in-force stage; the rest (flagged below) default from an absent stage: field, not a filed assertion. Each links to the register entry with its primary source.
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).
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.
Every tracked material is on the supply side — the strategy here is positioning, not substitution.
This company sits on the supply side of magnesium. Restrictions by 🇨🇳 CN push buyers toward ex-CN producers — the strategy is to be visible where those buyers look: the magnesium chokepoint page and the watchlist.
This company sits on the supply side of potash. Restrictions by 🇨🇦 CA push buyers toward ex-CA producers — the strategy is to be visible where those buyers look: the potash 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. The policy register files new measures daily and this page recomputes from it — the same chokepoints are monitored live on the watchlist and in the full register.
