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.
OFZ produces across 2 countries — 85% of mapped capacity sits in 🇸🇰 SK (HQ 🇸🇰 SK).
material exposures: manganese · silicon
No register action names OFZ yet — footprint only.
Its 2 scored input materials trace to 1 supplier country — 1 refines >70% in a single country. Top input chokepoint: 🇨🇳 China (manganese 90%, silicon 80%) — nearest ex-🇨🇳 manganese producer: 🇿🇦 South Africa ~5% — ~6-12mo to ramp (share-of-stage heuristic, not a sourced qualification time).Armed chokepoint: 🇨🇳 China has itself issued 3 register actions restricting the inputs it already dominates — silicon (2), manganese (1) — max severity 4/5. This share is a demonstrated lever, not just a concentration.Latest: China MOFCOM Preliminary Anti-Dumping Ruling on Japanese Dichlorosilane (DCS) Imports · 2026-09-07 · 29d ago

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.
