From mine to dealer: five tiers of supply-chain trust

Mines, exporters, importers, wholesalers and retail dealers each carry different signals. Understanding the chain helps buyers ask sharper questions.

Material moves through a predictable chain, and each step changes what a buyer should ask.

  1. Mine / producer — origin, extraction dates, permits
  2. Exporter — export documentation and country of origin
  3. Importer — customs, compliance, chain of custody
  4. Wholesaler / manufacturer — grading consistency and volume
  5. Retail dealer / collector — provenance history

Knowing where a counterparty sits tells you which questions actually matter.
