We surveyed 60 importers who bought microneedling devices in the last 18 months. The buyers who reported the smoothest projects all followed a similar evaluation sequence, and this guide lays it out.
Key Numbers to Compare
| Stage | Duration | Key Activity | Deliverable |
|---|---|---|---|
| Quote | 1-2 weeks | RFQ + doc review | Quotation |
| Sample | 2-3 weeks | Sampling + testing | Sample report |
| Audit | 1 week | Factory visit | Audit report |
| Production | 4-8 weeks | Manufacturing | Shipment |
