Request samples with the final specification, not an approximation.
In practice the decision comes down to three numbers: unit cost, freight per unit and the realistic sell through rate for Diamond 4.

A written internal standard for sample order workflow makes onboarding new account managers far quicker and reduces avoidable errors.
Checklist
- Retain one sealed sample carton from every batch for reference.
- Verify that artwork matches the approved compliance template.
- Review the reorder point after one full selling cycle.
- Keep certificates current and filed against the exact model name.
- Agree in advance who pays for return freight on a defect claim.
- Confirm the exact configuration in writing before the deposit is paid.
Commercial terms
Commercial terms are usually agreed in three parts: a deposit on confirmation, a balance before shipment and a stated validity window.
Agreeing a defect handling procedure before the first shipment removes emotion from later conversations.
