As it is not economically viable for most clients to inspect every unit in the order, AQL tables determine the number of units to be inspected which will yield a statistically reliable sample size. In other words, if the inspection on the randomly selected lot goes well, then it is statistically unlikely that defects will be found in the rest of the order. For the sake of example, say there are 100 master cartons in an order and 50 units per master carton for 5000 units total. Our inspectors would open at random a select set of master cartons (the square root of the total number of cartons) and further select at random a set of individual units inside that master carton as per sampling size chosen by the client. However, if the supplier knew they had a few dozen defects and packaged the defects all together in one section of one master carton, then it would be statistically unlikely that our inspector would find this pocket of defects. For this reason, AQF does not provide a warranty on behalf of the supplier. But we stress to our clients that they should have robust POs, warranty terms and payment terms with their suppliers that protect the interests of the client. Negotiating such terms with the supplier is outside of the scope of our business at Baidaa inspection, but our Endorsed Parters can help with the negotiations and contract review.
