This is a sole source solicitation for one structural bracket, with delivery under FOB origin terms. The government lacks sufficient technical data to contract with any source other than the current one. The item is subject to Free Trade Agreements and the WTO Government Procurement Agreement. The acquisition requires Government Source Approval prior to award, and approval of a new source typically cannot be completed in time to allow award. Any offeror that is not already an approved source must submit the required source approval data with its proposal.
