Coltan (Tantalite) — Ta₂O₅ 34% · 38% · 45%

Tantalite in three graded purities — 34%, 38%, and 45% Ta₂O₅ — from verified cooperatives in the Rwanda and DRC corridors, under Dodd-Frank Section 1502-aligned due diligence.

How this commodity clears the Zorem network: origin is verified against corridor documentation before any term sheet is drafted; independent assay precedes export; custody is serialized through bonded logistics to a recognized vault or refinery; and settlement executes against presented documents through the agreed instrument — SBLC, DLC, or confirmed wire. Indicative figures on this page reflect corridor norms; the numbers that settle are the ones on the destination assay certificate and the written contract.

Every engagement begins with a mandate and a trial lift — deliberately small, fully documented, and audited end-to-end — before any program scales. That sequence is how both sides prove the corridor without risking serious capital.
