These determinations are dependent upon the particular product, package, distribution system, market, customers, and other factors and can vary widely. Therefore product damage and allowable package degradation must be defined by the shipper, manufacturer, damage claim group, and/or other stakeholders and interested parties. In most cases, the shipper/manufacturer is in the best position to define product damage due to detailed familiarity with the product. Sometimes others may contribute to these determinations, including carriers and test lab personnel. But in any case, definition and agreement should be reached cooperatively among all entities concerned with safe arrival of the shipment, low damage rates, cost effective packaging, etc.
