What is During-Production Inspection (DPI)?

During-Production Inspection (DPI) is a random on-site check performed when 20–30% of the order is packed and ready, but before the bulk of the run is finished. It is the single most cost-effective inspection for medium and large orders, because defects found at this stage can still be reworked without delaying shipment. CGF inspectors visit the factory, draw a random sample from finished stock, run an AQL-based check, and report within 24 hours.

Key Benefits of During-Production Inspection (DPI)

When Should You Consider a During-Production Inspection (DPI)?

• Order quantity is 1,000 units or more.
• Product has a moderate-to-high defect risk (complex assembly, multiple components, softlines with prints).
• You want confirmation that the factory’s inline QC is actually working — not just claiming it is.
• You want a second pair of eyes before committing the rest of the production deposit.

What Does CGF Inspection Check During During-Production Inspection (DPI)?

Quantity & Production Status

• Total ordered quantity vs quantity already produced vs quantity in process.
• Daily output rate compared to the production schedule.
• Forecast finish date compared to your required ship date.

Random Sample Inspection (AQL)

• Sample size selected per ANSI/ASQ Z1.4 or ISO 2859-1 at the AQL level you specify (commonly 1.0 / 2.5 / 4.0).
• Each sampled unit inspected for: quantity per carton, assortment, style, colour, size run.
• Defects classified: Critical / Major / Minor.
• Pass / Fail decision based on the Accept / Reject numbers in the AQL table.

Workmanship

• Construction, stitching, bonding, welding, assembly integrity.
• Surface defects: scratches, dents, blemishes, contamination.
• Colour consistency across the run (no visible batch-to-batch shift).

Function & Performance

• Powered-on test for electronics.
• Mechanical function for moving parts.
• Pull / drop / torque tests for hardlines where applicable.

On-Site Tests

• Carton drop test on a sample carton.
• Tape adhesion and label legibility check.
• Polybag and desiccant presence where required.

Packing & Marking

• Inner packing matches the spec (quantity per inner pack, polybag, tissue).
• Master carton markings: bar code, shipping marks, side marks, country of origin.
• Shipping marks exactly match your PO and the carton label on each carton.
