Systematic Quality Gates Built into Every Production Stage
Effective quality management is an end-to-end engineering discipline, not a hasty check conducted as shipping containers are being loaded. Through systematic product inspection gates across every manufacturing milestone, Jino Sourcing catches deviations early to prevent costly project delays.
Guaranteed 24-Hour Inspection Reporting
Receive exhaustive English-language inspection dossiers complete with high-resolution photography, defect categorization breakdowns, dimension measurement logs, and clear pass/fail determinations within 24 hours of on-site completion.
Pre-Production Inspection (PPI) & Raw Material Testing
We verify incoming raw material specs, component batch authenticity, Pantone color accuracy, and tooling readiness before the factory powers up assembly lines. This gate stops substandard materials or unapproved component substitutions before mass production begins.
During Production Inspection (DUPRO)
Conducted once 20% to 50% of the purchase order has run through assembly. Our engineers cross-check semi-finished products against approved golden samples, evaluate operator adherence to SOPs, measure output defect rates, and correct tooling alignment issues in real time.
Pre-Shipment Inspection (PSI / FRI)
Executed when 100% of the production run is completed and at least 80% is fully packaged into master cartons. Following ISO 2859-1 standards, our inspectors evaluate cosmetic appearance, mechanical assembly, electrical ratings, packaging drop resilience, and retail labeling accuracy.
Container Loading Supervision (CLS)
Guarantees that your verified merchandise is loaded carefully into clean, structurally sound, and weather-sealed freight containers. Our inspectors audit carton quantities, monitor pallet stacking integrity, verify weight distribution, and affix tamper-evident security seals.
Defect Classification Framework & Action Protocols
We categorize deviations using globally recognized AQL standards, giving procurement teams clear, data-driven criteria to authorize or hold supplier balance payments.
| Defect Classification | Definition & Scope | Target Threshold (AQL) | Jino Sourcing Action Protocol |
|---|---|---|---|
| Critical Defect | Safety non-compliance, electrical hazard, sharp burr, toxic coating, or breach of import regulations. | 0.0 (Zero Tolerance) | Immediate shipment block; 100% factory quarantine, mandatory root-cause teardown, and total lot rework. |
| Major Defect | Functional failure, structural dimension mismatch, incorrect branding, or defects causing end-user returns. | AQL 2.5 (Industry Standard) | Supervised sorting and on-site factory rework; mandatory secondary inspection before balance release. |
| Minor Defect | Slight cosmetic imperfection, minor paint unevenness, or light packaging mark not affecting product performance. | AQL 4.0 (Industry Standard) | Detailed logging with high-resolution photos; submitted in inspection dossier for formal buyer sign-off. |
| Custom Tooling Checks | Mold dimensional drift, parting line flash, core pin wear, cooling channel integrity, and steel hardness specs. | Tolerance Target (±0.02 mm) | CMM sample validation, tooling maintenance log audit, and physical serial engraving for asset ownership locking. |
