Carton Selection Procedure in Final Shipment Inspection

Question: How many cartons i need to select for final inspection in AQL 2.5 point system if garments quantity is 10,000 pieces. Please advice. ... asked by Didarul.

The total number of cartons to be selected for the final inspection does not depend on AQL as instructed for final inspection level or order quantity or quantity to be inspected.

At the time of final inspection of a shipment, the Sampling plan is done based on the total quantity that needs to be inspected (10000 pcs). In this case, total 200 pieces to be checked according to ANSI/ASQ Z 1.4 Sampling procedures.

Whether a shipment will be accepted or rejected is decided based on AQL level. In the above example, based on AQL 2.5, up to 10 defective pieces is acceptable in the shipment.

Carton Selection Procedure

Carton selection depends on the following parameters

  • Total number of cartons,
  • Garment size and
  • Colourways.

The highest number of the cartons (always rounded up) between the two following:

1. The square root of the total number of cartons of the lot (In this case: Try to respect the proportion of each size and colour of the whole lot).
For example, total 100 carton, 4 sizes, 1 color --> square root 100 > 4X1 = 10 cartons

2. The lowest number of cartons required drawing some samples (i.e. One carton per size per colour).
For example, total 100 carton, 4 sizes, 3 color --> square root 100 < 4X3 = 12 cartons
