FAR 12.3—Subpart 12.3

Scope of subpart.

FAR 12.300 is the scope statement for FAR Subpart 12.3, and it tells contracting officers and contractors that this subpart is about the provisions and clauses used when buying commercial products and commercial services. In practical terms, it does not itself create a detailed buying procedure; instead, it identifies the clause and provision framework that applies when an acquisition is being conducted under the commercial-item rules of FAR Part 12. The section matters because commercial acquisitions are intended to use streamlined, market-based terms rather than the full set of noncommercial contract clauses, so the scope statement signals that the focus is on selecting the right commercial provisions and clauses for the solicitation and contract. It also helps distinguish commercial buying from other acquisition types by tying the subpart specifically to commercial products and commercial services. For practitioners, this means the key question is not whether the government is buying something, but whether the item or service qualifies as commercial and therefore triggers the clause set in Subpart 12.3.

Solicitation provisions and contract clauses for the acquisition of commercial products and commercial services.

FAR 12.301 sets the baseline rule for what solicitation provisions and contract clauses may be used when buying commercial products and commercial services. Its purpose is to keep commercial-item acquisitions as streamlined as possible, consistent with 41 U.S.C. 3307, by limiting clauses to those required by law or executive order or those consistent with customary commercial practice. The section identifies the core commercial-item provisions and clauses that must be used: 52.212-1, Instructions to Offerors—Commercial Products and Commercial Services; 52.212-3, Offeror Representations and Certifications—Commercial Products and Commercial Services; 52.212-4, Contract Terms and Conditions—Commercial Products and Commercial Services; and 52.212-5, Contract Terms and Conditions Required to Implement Statutes or Executive Orders—Commercial Products and Commercial Services. It also explains when evaluation provisions may be added, how other FAR-required provisions and clauses still apply in commercial buys, and which commercial-item clauses may not be tailored. In practice, this section is the central roadmap for drafting commercial solicitations and awards: it tells contracting officers what must be included, what may be tailored, what alternates apply, and how to avoid overloading commercial acquisitions with noncommercial terms.

Tailoring of provisions and clauses for the acquisition of commercial products and commercial services.

FAR 12.302 explains how contracting officers may tailor the standard commercial-item and commercial-service solicitation and contract terms to fit the specific market being bought from, while still preserving the core statutory protections that cannot be changed. It covers the general authority to tailor FAR 52.212-1, Instructions to Offerors—Commercial Products and Commercial Services, and FAR 52.212-4, Contract Terms and Conditions—Commercial Products and Commercial Services, based on market research and commercial market practices. It also identifies the specific paragraphs of 52.212-4 that may not be tailored because they implement statutory requirements: assignments, disputes, payment (with a limited exception in subpart 32.11), invoice, other compliances, compliance with laws unique to Government contracts, and unauthorized obligations. The section further restricts the Government from adding terms inconsistent with customary commercial practice unless a waiver is approved under agency procedures, and it requires the waiver request to document the market practice, the need for the inconsistent term, and why the customary practice does not meet Government needs. Finally, it requires tailoring to be done by addenda to the solicitation and contract, including proper notation on SF 1449 Block 27a, and gives examples of what those addenda may contain, such as schedule continuations, expanded descriptions, additional terms, options, ordering procedures, warranties, and financing arrangements. In practice, this section is the main guardrail for keeping commercial acquisitions commercially aligned while allowing necessary Government-specific adjustments.

Contract format.

FAR 12.303 explains the preferred contract and solicitation format for acquisitions of commercial products and commercial services under FAR part 12. It tells contracting officers how to assemble the solicitation/contract package using Standard Form 1449 and which blocks on that form may be continued or completed for items such as incentive subcontracting percentages, remittance address, line item numbers, schedule of supplies or services, and accounting data. It also identifies the commercial-item clause set that should be incorporated, including FAR 52.212-4, any addendum to that clause, and FAR 52.212-5, as well as the solicitation provisions typically used, including FAR 52.212-1, any addendum to that provision, FAR 52.212-2 if evaluation factors are being used, and FAR 52.212-3. The section also recognizes that contract documents, exhibits, and attachments may be part of the package. In practice, this rule is about keeping commercial acquisitions streamlined, standardized, and easy for vendors to understand, while still allowing the government to include the specific information needed to administer the buy and evaluate offers properly.
