GASKET
Solicitation # SPE7L3-26-T-171D
Offerors must comply with strict domestic sourcing requirements under the Berry Amendment and Buy American Act, with the Berry threshold now set at $150,000, requiring full disclosure of any non-domestic materials used in quoted items. The solicitation prohibits the use of covered telecommunications equipment or services as defined by FAR 52.204-24 and DFARS 252.204-7016, and no items produced via additive manufacturing may be included unless explicitly approved by the contracting officer. Due to fluctuating demand, offerors are strongly encouraged to provide quantity ranges rather than fixed numbers to allow buyers flexibility in combining or adjusting requirements without additional administrative steps, though this does not apply to Auto IDC. All offerors submitting quotes must ensure they are registered or will register via DLA’s Account Management & Provisioning System to gain access to the Vendor Shipment Module, with contractors using VSM WebServices required to update their internal schema by the specified deadline; failure to do so will result in loss of shipping ability. Small business joint ventures must submit all required representations under FAR provisions 52.212-3 and 52.219-1 for applicable categories. Offerors who cannot submit a bid by the closing date must file a “No Bid” on DIBBS with an anticipated quote date or reason, to avoid assumptions of non-responsiveness. Fast Pay is not applicable, and all quotations must reference the correct NSN and purchase request. APEX Accelerators offers free assistance to businesses seeking to compete for government contracts. The item in question is a gasket, with a required quantity of 75 units to be delivered within 264 days to Cherry Point, North Carolina, under solicitation SPE7L3-26-T-171D, and all responses must be submitted via DIBBS before the deadline.
