FAR 52.215-10 Price Reduction for Defective Certified Cost or Pricing Data

Does the regulation require it to flow down?

No

Operates at the prime level: (a)(2) authorizes reducing the prime's price when 'a subcontractor or prospective subcontractor' furnished data that were not complete/accurate/current; (b) limits the reduction in the case of a prospective sub that did not win the subcontract; primes paste it into the PO as a mirroring convenience

A clause can reach your subcontract without a mandate. Once it is in your document, it is a contract term all the same. The missing mandate is a fact about the regulation. It is not a ruling on your order.

What it makes you produce

One item for your checklist.

  1. Nothing to send now

    It does not hold the order. It decides what money moves later — what you can claim, what can be claimed from you, and what can be held back — and none of that changes after signature.

When it is used

Enters the prime's contract when certified cost or pricing data were required (TINA — negotiated, above $2.5M since 2025-10-01, with no adequate-competition/market-price/commercial-item exception). It reaches the sub WITHOUT this clause being inserted: (a)(2) allows reducing the prime's price for defective data furnished by a subcontractor or prospective sub — what flows down into your contract is its sister 52.215-12/-13. (Trigger corrected 2026-08-05, backlog item 12: the entry gated on the dollar threshold and `commercial == false` and stopped there, so a non-commercial order above the threshold came out `applies` — deciding a question 15.408 leaves to 15.403-1(b). The family was also inconsistent with itself: 52.215-11 and 52.215-21 carried a structural leg for this and 52.215-10, -12, -13 and -20 did not. Prescription verified against acquisition.gov, FAR 15.408.)

Read closely

The mechanism runs one level up: paragraph (a)(2) reduces the price above you for data a subcontractor or prospective subcontractor furnished that was not complete, accurate and current, and paragraph (b) limits that reduction where the prospective supplier did not win the work. The contract you signed is how the reduction travels back down.
