FSS contracts provide various expedited delivery terms. Generally, the alteration of or tailoring of a Federal Supply Schedule contract terms and conditions to meet the needs of individual procurements are not permitted. Such tailoring may violate the Competition in Contracting Act of 1984 (CICA) and alter the scope of the contract. Tailoring for a special requirement is permitted only if appropriate and the schedule contract allows for it. For example, FSS contracts provide various expedited delivery terms. A customer may be able to obtain faster delivery for special requirements.
