Amazon calculates ASN accuracy and receiving chargebacks using the supplier’s 7-day defect rate. This rate shows how many units had defects compared to total units received. The chargeback applies to the total cost of all defective products in your shipment.  

For example, if a shipment arrives without an advance shipment notice and contains only one product, the supplier pays the chargeback percentage on that product's cost (see the chart below). If the shipment contains 5 products, the supplier pays the chargeback percentage on the combined cost of all 5 products.
