(b) Although "proposal" and "offeror" may be used in this RFI, your response will be treated as information only. It shall not be used as a proposal. (c) This RFI is issued as part of market research for a 440VAC Regulator. This is NOT A SOLICITATION FOR PROPOSALS and no contract will be awarded from this RFI. If a solicitation is issued in the future, it will be announced via SAM.gov and interested parties must comply with that announcement. It is the responsibility of interested parties to monitor SAM.gov for additional information pertaining to this requirement. Any small businesses that believe they can accomplish this entire requirement should indicate their small business status (see FAR Part 19) in their response. Questions regarding this announcement shall be submitted in writing via e-mail to the Contract Specialist’s email addresses. Verbal questions will not be accepted.
