Only bids submitted through the official solicitation portal will be accepted; emailed submissions will not be considered. This is a brand-name-or-equal solicitation, and equal products must demonstrate that they meet or exceed all salient physical, functional, or performance characteristics. A completed Buy American form is mandatory, and bids without it may be deemed non-responsive and rejected. Pricing must include all shipping, packaging, and inspection charges, with a single shipment and invoice required unless multiple shipments receive prior written approval from the WDTC S2P2 point of contact.
