Standard Form 18 (SF 18): Request for Quotation
Standard Form 18 (SF 18), Request for Quotation, is a one-page form a Government issuing office uses to ask a supplier for price quotations. It prints (THIS IS NOT AN ORDER) under its title. The footer says it is prescribed by GSA-FAR (48 CFR) 53.215-1(a), Rev. 6/1995, and GSA hosts a copy in its forms library.
The upper blocks identify the request: the request number, the issuing office, the delivery date and destination, the supplier it is sent to and the date quotations are due. The schedule lists supplies or services with quantity, unit, unit price and amount, followed by a discount for prompt payment and the name, address and signature of the quoter. The form says this is a request for information and quotations furnished are not offers.
The form is marked Authorized for local reproduction and says the previous edition is not usable. You can fill it out free in your browser on this page and download the result without an account.
