Use of forms.
FAR 43.301 explains which government forms must be used to document contract and solicitation changes, and when a different form or attachment is allowed. Its main focus is the Standard Form 30 (SF 30), Amendment of Solicitation/Modification of Contract, which is the default form for amendments to solicitations, unilateral contract modifications under contract clauses, administrative changes, supplemental agreements, and funding actions such as adding, removing, or reinstating funds. It also identifies limited situations where the SF 30 may be used instead of being required, including certain petroleum economic price adjustments, termination notices, and purchase order modifications under FAR 13.302-3. In addition, it addresses a key disclosure rule: if a change is expected to affect price, the estimated price change must not be shown on the contractor’s copy of the SF 30. Finally, it allows use of Optional Form 336 or plain paper as a continuation sheet for longer modifications. In practice, this section is about ensuring contract changes are documented consistently, clearly, and without revealing tentative pricing information to the contractor before the government is ready to finalize it.
