At the early stage of production, usually after 5–10% of the order has been completed.

To ensure production processes, workmanship, and capacity align with requirements before full output continues.

• Assembly procedures and worker training
• Machine calibration and maintenance
• In-process quality control checks by the factory
• Sampled product dimensions, functions, and finish quality
• Identification of process errors that could multiply across the full order
• Production schedule and capacity compared to order deadlines

After 100% of production is finished and at least 80% of goods are packaged for shipment.

To provide final confirmation that the goods meet specifications before they leave the factory.

• Random sampling of finished products (AQL standards are common)
• Functional, performance, and safety testing
• Visual checks for cosmetic defects (scratches, dents, contamination)
• Packaging quality (drop tests, sealing, barcodes, labeling accuracy)
• Quantity verification and carton integrity
• Compliance with client’s shipping requirements

During the loading of finished goods into the shipping container, typically at the factory and before the container is sealed and transported to the port.

To confirm that the correct goods are loaded properly, protected during transit, and shipped exactly as approved.

• Verification that the correct products, models, and quantities are loaded
• Carton condition and packaging integrity during handling
• Proper loading sequence and weight distribution inside the container
• Condition of the shipping container (cleanliness, dryness, damage)
• Correct palletization, bracing, and use of protective materials
• Container sealing and seal number verification
• Alignment with packing lists, shipping documents, and client requirements
