Pick a company to see where it actually produces — every country in its footprint, shaded by capacity share — overlaid with the countries whose register actions name it (severity ring + action count), plus violet arcs to the chokepoint countries its material inputs depend on. The map is a lens; the dossier and register are the source of record.
H.C. Starck Tungsten produces across 3 countries — 62% of mapped capacity sits in 🇩🇪 Germany (HQ 🇩🇪 Germany).
material exposures: tungsten · tantalum · niobium
No register action names H.C. Starck Tungsten yet — footprint only.
Its 3 scored input materials trace to 2 supplier countries — 2 refine >70% in a single country. Top input chokepoint: 🇨🇳 China (tungsten 90%, tantalum 50%) — nearest ex-🇨🇳 tungsten producer: 🇦🇹 Austria ~4% — ~6-12mo to ramp (share-of-stage heuristic, not a sourced qualification time).Armed chokepoint: 🇨🇳 China has itself issued 4 register actions restricting the input it already dominates — tungsten (4) — max severity 5/5. This share is a demonstrated lever, not just a concentration.Latest: China State Council Order No. 839 — Regulations for the Implementation of the Mineral Resources Law · 2026-05-20 · 141d ago

Overlap node: 🇨🇳 China sits in two of the three layers — 23% of mapped capacity · dominant world supplier of 2 scored inputs (tungsten 90%). It hosts capacity AND controls an input feeding it — a two-sided lever.

Reading the map: green shading = the company's production countries by capacity share, with dots at facility cities (dashed = approximate, country-level). Violet arcs = INPUT DEPENDENCIES — they run from the country that dominates world production/refining of a material the company consumes to the company's base; the % is that country's share of world supply at the named stage, NOT an import/export volume. Severity rings = countries whose register actions name the company.
