How this list is built

Sources: China SAMR business registry (公司名、统一社会信用代码), public company filings, and capability data extracted from mill websites. Customs records (ImportYeti / Panjiva) are on the roadmap, not yet integrated. No paid placements; ranking is editorial, not pay-to-play.

Tier A = audit-grade verified (registry + export share + capacity disclosed). Tier B = registry-verified with partial operational data. Tier C suppliers are excluded from this aggregation to keep the page useful for buyers.
