Quality Inspection
Pre-production, during-production, pre-shipment QC. Three checkpoints that catch problems before they become containers of defects.
A pre-shipment inspection on 2,000 units costs $250. Returning 2,000 defective units from Germany costs $8,000–12,000 plus 6 weeks of delay and a damaged customer relationship. The math is simple.
Three-Stage QC
Pre-production inspection Before materials are committed. We verify the factory has received correct components, the right BOM version is in use, tooling is correct, and line workers are briefed on your specific requirements. Most defects are designed in at this stage.
During-production inspection (DUPRO) At 20–30% production completion. We pull samples from the line, run functional tests, check cosmetic standards, and verify packaging materials. Problems caught here can still be fixed before the full run is affected.
Pre-shipment inspection (PSI) At 80–100% production, before goods are loaded. Standard AQL sampling (typically 2.5 for major defects, 4.0 for minor). We run a full product checklist, test random units, verify carton markings, and confirm shipment quantities.
What We Check

- Cosmetic: scratches, color consistency, assembly gaps
- Functional: power-on, connectivity, button response
- Electrical safety: insulation resistance, withstand voltage
- Drop test (carton level)
- Barcode / QR scan verification
- Label and regulatory marking accuracy
- Quantity count vs. packing list
