Eight steps from inquiry to settlement
- 1. Inquiry and indicative quotation Confirm material, grade, quantity, delivery term and pricing unit. Indicative pricing is given against the actual lot, never as a fixed public price list.
- 2. Authenticity verification Review ownership evidence, warehouse receipts, mining or export permits, purchase contracts and prior export records before commercial discussion continues.
- 3. Terms alignment Agree the pricing basis, assay standard, moisture and impurity deductions, delivery window and dispute-resolution method in writing.
- 4. Qualification exchange Both sides exchange business registration, export licence, bank account details and other documents required for a compliant cross-border transaction.
- 5. Contract signing Execute the sales contract or tripartite agreement according to the agreed model: long-term offtake, spot lot, or buyer-bidding mandate.
- 6. Pre-shipment inspection Sampling and assay by an independent inspection body such as SGS, Intertek or CCIC, with samples sealed and retained by the parties involved.
- 7. Process supervision Track loading, export declaration, transport documents, weighing records and arrival milestones, with site photos and records kept for each lot.
- 8. Documents and settlement The seller submits the document set, RTV reviews it, and payment, title transfer and settlement close the transaction loop.
