Agency controls
June 9, 2020
Agencies shall establish the necessary controls to identify shelf-life items on their stock records (and in other appropriate elements of their supply system), and shall determine the appropriate shelf life for other than GSA managed items. Shelf-life items shall be stored in such a way as to ensure that the oldest stock on hand is issued first. Agencies shall issue the oldest stock of shelf-life items first except when it is not feasible as in shipments to overseas activities.
