FAR 15.403-2 Other circumstances where certified cost or pricing data are not required.
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 lists two situations where certified cost or pricing data are not required. It matters because it tells contractors when they can avoid submitting that data, such as when exercising an option at an already-established price or when proposals are only for overrun funding or interim billing price adjustments.
Applies to: Contractors submitting proposals in these specific circumstances
Key terms: certified cost or pricing data · option · overrun funding · interim billing price adjustments
