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.
SK Siltron produces across 1 country — 100% of mapped capacity sits in 🇰🇷 South Korea (HQ 🇰🇷 South Korea).
material exposures: silicon · graphite
1 register action name SK Siltron, issued from 1 country (top: 🇰🇷 South Korea ×1) — 1 of those also sit in its production footprint (regulator ∩ producer).

Its 2 scored input materials trace to 1 supplier country — 1 refines >70% in a single country. Top input chokepoint: 🇨🇳 China (graphite 85%, silicon 80%) — nearest ex-🇨🇳 graphite producer: 🇯🇵 Japan ~5% — ~6-12mo to ramp (share-of-stage heuristic, not a sourced qualification time).Armed chokepoint: 🇨🇳 China has itself issued 9 register actions restricting the inputs it already dominates — graphite (6), silicon (2), artificial graphite anode materials (1) — max severity 5/5. 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 · 30d ago

Overlap node: 🇰🇷 South Korea sits in two of the three layers — 100% of mapped capacity · 1 action naming SK Siltron (max sev 3/5). It regulates the company inside its own borders — exposure is operational, not just trade-facing. its KR actions →
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.
