A sole source procurement for 13 units of a specific referenced item, with delivery FOB origin. The government lacks sufficient, accurate, or legible data to contract with other than the current source. The items are subject to Free Trade Agreements and WTO Government Procurement Agreement provisions and require Government Source Approval prior to award. Offerors not already approved must submit the required source approval data with their proposal, as failure to do so will disqualify them from consideration.
