Both PW2, PW3 and PW4 testified that the ullage is recognised in the industry to cater for unexplainable surplus and shortage in stocks. The attention of the court was also drawn to the write up in the Australian Logistic Bureau adduced by PW2 which says, Ullage is a term that historically refers to the quantity of liquid within a container that is lost, by leakage, during shipment or storage. The word has now developed a wider logistical meaning and is often used in contracts to define inventory losses in a warehouse facility that are unexplainable. For example, short deliveries that were not picked up, inaccuracies resulting from miscounts, oversupply or undersupply to a customer, pilferage and data entry errors. While clients want perfect inventory management, the reality is that there is no such thing. Most companies suffer inaccuracies in the range of 0.1-2.5% of stock value. Accordingly warehouse providers may insert a ‘no liability’ clause in their contracts that specifically excludes them from ullage responsibility. Customers, however typically have difficulty accepting ullage allowances, believing that their 3PL should be accountable for anything short of 100% accuracy. So the pre-contract debate can be hot on this issue.
