How these lists are different
No paid placements
Mills cannot pay to appear on or improve their position in any ranking. If that ever changes, it will be labeled "Sponsored" on every page.
Methodology published per list
Each ranking has a dedicated methodology section: data sources, weighting, tie-breakers, and exclusions. Score breakdown shown per entry.
Public data only
China SAMR registry, listed-company disclosures, and public rosters. Customs-record aggregation (ImportYeti / Panjiva) and third-party certification registries are on the roadmap. No leaked data.
Updated on a schedule
Flagship lists refresh annually. Market-specific lists refresh quarterly. Every entry shows its last-verified date.
