FAR 43.107 Contract clause.
The codified text (eCFR, as of 2026-10-02). Under the Revolutionary FAR Overhaul ↗, agencies follow class deviations with new text for many parts while the formal rules go through the Federal Register: check the solicitation and your contract's clauses, which rule.
In plain English
This section tells contracting officers when they may include the Notification of Changes clause (52.243-7) in solicitations and contracts. It is mainly intended for negotiated research and development or supply contracts for major weapon systems or principal subsystems. The clause generally must not be used if the contract amount is expected to be under $1,000,000, unless the contracting officer anticipates a dispute about alleged changes.
Applies to: Contracting officers awarding negotiated research and development or supply contracts, primarily for major weapon systems or principal subsystems

The text
The contracting officer may insert a clause substantially the same as the clause at 52.243-7, Notification of Changes, in solicitations and contracts. The clause is available for use primarily in negotiated research and development or supply contracts for the acquisition of major weapon systems or principal subsystems. If the contract amount is expected to be less than $1,000,000, the clause shall not be used, unless the contracting officer anticipates that situations will arise that may result in a contractor alleging that the Government has effected changes other than those identified as such in writing and signed by the contracting officer.
