Bids must be submitted through the official solicitation portal; emailed submissions will not be accepted. This is a brand-name-or-equal solicitation, and equal products must demonstrate compliance with all salient physical, functional, or performance characteristics. A completed Buy American form is mandatory, and missing it may cause rejection as non-responsive. Pricing must include all shipping, packaging, and inspection charges, with a single shipment and invoice required unless prior written approval is obtained from the WDTC S2P2 Point of Contact.
