This document outlines new requirements for heat treated pallets used to store and transport pharmaceutical raw materials and components at ILC Dover Supply Chain facilities. Effective June 10, 2013, only clean heat treated pallets stamped with ISPM 15 - HT can be used for pharmaceutical materials. Pharmaceutical materials must be kept separate from non-pharmaceutical items and cannot be stored next to non-heat treated pallets. The changes are being implemented to comply with customers' strict cleanliness standards due to the critical nature of their work. ISPM 15 heat treated pallets undergo high temperature treatment to prevent the spread of insects and disease between countries.
