Commercial Products & Services (Part 12)

FAR 52.212-4

Contract Terms and Conditions—Commercial Products and Commercial Services

The 'commercial-item terms' that replace the mass of Part 49 / Part 32 clauses in non-commercial contracts. Covers inspection/acceptance, assignments, changes (bilateral only), disputes (Contract Disputes Act), excusable delays, invoices, payment, patent indemnity, taxes, termination for the Government's convenience, termination for cause, title, warranty, and limitation of liability.

FAR / DFARS Part
FAR Part 12 — Acquisition of Commercial Products and Commercial Services
Prescribed By
FAR 12.301(b)(3) — Required in all solicitations and contracts for commercial products and commercial services.
Flow-down to Subcontracts

Per 52.244-6, the prime must include certain commercial-item clauses in subcontracts (52.222-21, 52.222-26, 52.222-50, 52.225-13, 52.247-64, and CMMC/Section 889 as triggered). 52.212-4 itself is not flowed down verbatim.

What this clause requires

  • 1Changes are bilateral only — the Government cannot unilaterally direct out-of-scope changes (unlike 52.243-1).
  • 2Termination for convenience entitles the contractor to a 'percentage of the contract price reflecting the percentage of work performed' plus reasonable charges (not the full Part 49 settlement).
  • 3Termination for cause is the commercial-buy equivalent of default; the contractor is liable for excess reprocurement costs.
  • 4Invoices must include the items, quantities, unit prices, UEI, shipping/payment terms, and any required taxpayer ID.
  • 5Standard commercial warranty applies unless the contract states otherwise (or 52.212-4 Alt I is used).
  • 6Disputes are resolved under the Contract Disputes Act (41 U.S.C. Chap. 71).

When this clause applies

All Part 12 commercial-item awards. If the CO has tailored under 12.302, the changes will be explicitly identified. Tailorings that conflict with customary commercial practice require a waiver per 12.302(c).

Alternates

Alt IWhen the contract is awarded on a time-and-materials or labor-hour basis (FAR 12.207(b)).

Common pitfalls

!Treating 52.212-4 changes like 52.243-1 — the Government cannot unilaterally direct extra work; if asked to perform out-of-scope, demand a bilateral modification first.
!Missing the 30-day window to assert excusable delay under paragraph (f) — notify the CO promptly in writing.
!Underestimating termination-for-cause exposure — reprocurement costs can be many times the contract price.
!Ignoring the 'limitation of liability' paragraph (o) which caps contractor liability at the contract price for most consequential damages — but exceptions (IP indemnity, third-party claims) survive.

Proposal-team checklist

  • ☐Read every CO tailoring at 12.302 — most disputes arise from tailorings that the contractor didn't price.
  • ☐Confirm invoice format matches paragraph (g)(1) plus any agency-specific instructions (e.g., DFAS WAWF).
  • ☐Build a written notification template for excusable delays and submit within days, not weeks.
  • ☐Reserve a contingency line in pricing if Alt I (T&M) is used — labor categories must match approved rates.

FAQ

Can the CO unilaterally change my SOW under 52.212-4?

No. Paragraph (c) makes changes bilateral. If the CO directs additional work without a bilateral mod, document immediately and submit a Request for Equitable Adjustment or a claim under the Contract Disputes Act.

What is the difference between termination for convenience and for cause?

Convenience (paragraph (l)): contractor receives the percentage of contract price for work performed plus reasonable charges. Cause (paragraph (m)): equivalent of default — contractor is liable for excess reprocurement costs and is not paid for partially completed work.

Does 52.212-4 include a Christian doctrine equivalent?

Mandatory commercial-item clauses are read into the contract whether or not physically included, but the doctrine is narrower in Part 12. The CO's tailoring decisions at 12.302 control.
