Orders

MOQ varies by product category and manufacturer. Surgical instruments typically start at 100 units per SKU; sports goods at 500 pieces; leather goods at 200 units. We can negotiate lower MOQs for new buyers placing trial orders.
Standard production lead time is 4–8 weeks depending on product complexity and order volume. Rush orders (2–3 weeks) are available for select manufacturers at a premium.

Quality

We conduct physical factory audits before onboarding any manufacturer. All our partners hold ISO, CE, or relevant certifications. We share full audit reports with buyers upon request.
Our manufacturers are certified under ISO 9001, ISO 13485 (surgical), FIFA Quality Pro (sports), and REACH/RoHS (chemicals). We conduct pre-shipment QC inspections on every order.
