What is the minimum solicitation response time authorized for a sole-source supply item estimated at $250,000?

The minimum solicitation response time for a sole-source supply item is determined by the principle of providing a reasonable opportunity for potential suppliers to respond. In sole-source situations, the urgency of the need and the uniqueness of the source may dictate a shorter time frame; however, there is no strict mandated minimum that applies uniformly, unlike competitive procurements where specific time frames such as 30, 45, or 15 days may be set.

By establishing a standard of "reasonable opportunity," the contracting authority allows for flexibility based on the nature of the procurement, the complexity of the items involved, and the time needed for suppliers to prepare their responses. This aligns with federal acquisition regulations that aim to balance the need for timely procurement with the necessity of fair competition processes. It is essential that the response time reflects both the urgency of the requirement and the opportunity for prospective vendors to gather the necessary information to formulate a valid proposal.

In contrast, the other options suggest fixed time frames that do not account for the specific circumstances of a sole-source procurement, where the decision can be made based on what is deemed reasonable under the given conditions.
