Before manufacturing begins, QGS inspects the raw materials and components to confirm they comply with your specifications and are available in the required quantity. This step is particularly important when dealing with new suppliers or outsourced components, helping to prevent production delays or quality issues from the outset.

Conducted when approximately 20-60% of production is complete, this inspection helps detect quality issues as they arise. DPI is valuable in identifying consistent defects and understanding where they occur in the production process—enabling real-time corrections and smoother final output.

Performed after production is completed and before goods are shipped, this inspection ensures the products meet all your specifications. PSI is the most commonly used inspection service and is particularly useful when you have ongoing relationships with trusted suppliers but want to verify quality before delivery.

When absolute precision matters, QGS offers piece-by-piece inspections—before or after packaging. Every unit is evaluated individually for workmanship, visual appearance, safety, function, and compliance with your defined standards. This service is ideal for high-value or high-risk products.

QGS inspectors monitor the entire container loading process to ensure the correct goods are being shipped, quantities are accurate, packaging is secure, and loading follows compliance standards. This is the final quality checkpoint before your shipment departs.
