NO SUB definition

NO SUB means NO Substitution of the specified item is acceptable; and if the Bidder cannot provide the exact product and exact packaging specified, “N/A” should be inserted in the price line. Including a bid price for an alternate product in this case will be considered non-responsive and not be considered.
NO SUB. Items: Items with a “Sole Brand” or “No Sub” designation in the description shall be furnished as the specified manufacturer and model/part number. No exception may be taken to the specification, and no alternate shall be accepted. In those cases where a manufacturer has discontinued the specified model/part number, the bidder shall indicate so on the RFQ. If a replacement item is available, the new model/part number shall be indicated on the RFQ form and the price quoted. It shall also be noted whether the replacement item is a direct replacement for the obsolete part number originally requested. If not, or if the specifications differ in any way, the bidder shall explain in detail, and corresponding drawings or descriptive literature shall be included with the quote.
