FAR 12.302—Tailoring of provisions and clauses for the acquisition of commercial products and commercial services.
Plain-English Summary
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.
Key Rules
Tailor to market conditions
Contracting officers may tailor 52.212-1 and 52.212-4 to fit the acquisition, but only within the limits of this subpart and after appropriate market research. The goal is to reflect commercial market practices rather than impose unnecessary Government-specific terms.
Core clauses are untouchable
Certain paragraphs of 52.212-4 implement statutory requirements and cannot be tailored: assignments, disputes, payment except as allowed under subpart 32.11, invoice, other compliances, compliance with laws unique to Government contracts, and unauthorized obligations. These provisions must remain intact in commercial acquisitions.
No inconsistency with commercial practice
The contracting officer may not add terms or tailor clauses in a way that conflicts with customary commercial practice for the item being acquired unless a waiver is approved under agency procedures. This protects the commercial nature of the acquisition and prevents unnecessary noncommercial terms from being inserted.
Waiver requires a documented justification
If a term inconsistent with customary commercial practice is needed, the waiver request must identify the market practice, explain why the inconsistent term is necessary, and determine that the customary practice does not satisfy Government needs. A waiver may be sought for one contract or a class of contracts for the specific item.
Tailoring must be done by addenda
Any tailoring must be made through addenda to the solicitation and contract, not by informal edits or hidden changes. The contracting officer must indicate in SF 1449 Block 27a that addenda are attached.
Addenda may expand details and terms
Addenda can be used to continue the schedule, further describe supplies or services, elaborate on SF 1449 items, and add necessary performance terms such as options, ordering procedures for indefinite-delivery contracts, warranties, and contract financing arrangements.
Responsibilities
Contracting Officer
Conduct appropriate market research, determine what tailoring is permissible, preserve the non-tailorable statutory clauses, avoid terms inconsistent with customary commercial practice unless a waiver is approved, prepare addenda to the solicitation and contract, and mark SF 1449 Block 27a when addenda are attached.
Agency
Establish procedures for approving waivers when the Government needs terms inconsistent with customary commercial practice, and ensure contracting personnel apply commercial-item tailoring rules consistently.
Offerors/Contractors
Review the tailored solicitation and contract terms, understand any addenda that modify the standard commercial terms, and comply with the resulting contract requirements, including any approved nonstandard terms.
Practical Implications
This section is the main reason commercial acquisitions stay commercially oriented instead of becoming mini noncommercial procurements; the contracting officer must start from market practice, not from a default Government template.
A common pitfall is over-tailoring—adding Government-specific clauses or requirements simply because they are familiar, rather than because market research and the acquisition need justify them.
Another frequent mistake is trying to change one of the protected 52.212-4 paragraphs; those provisions are fixed unless another FAR provision expressly allows a limited exception.
If a requirement departs from customary commercial practice, the file should clearly show the market research and waiver rationale; otherwise the solicitation is vulnerable to protest or internal review findings.
Because tailoring must be done through addenda and clearly identified on SF 1449, sloppy drafting or incomplete attachments can create ambiguity about what terms actually govern the contract.
Official Regulatory Text
(a) General . The provisions and clauses established in this subpart are intended to address, to the maximum extent practicable, commercial market practices for a wide range of potential Government acquisitions of commercial products and commercial services. However, because of the broad range of commercial products and commercial services acquired by the Government, variations in commercial practices, and the relative volume of the Government’s acquisitions in the specific market, contracting officers may, within the limitations of this subpart, and after conducting appropriate market research, tailor the provision at 52.212-1 , Instructions to Offerors-Commercial Products and Commercial Services, and the clause at 52.212-4 , Contract Terms and Conditions-Commercial Products and Commercial Services, to adapt to the market conditions for each acquisition. (b) Tailoring 52.212-4 , Contract Terms and Conditions-Commercial Products and Commercial Services . The following paragraphs of the clause at 52.212-4 , Contract Terms and Conditions-Commercial Products and Commercial Services, implement statutory requirements and shall not be tailored— (1) Assignments; (2) Disputes; (3) Payment (except as provided in subpart 32.11 ); (4) Invoice; (5) Other compliances; (6) Compliance with laws unique to Government contracts; and (7) Unauthorized obligations. (c) Tailoring inconsistent with customary commercial practice . The contracting officer shall not tailor any clause or otherwise include any additional terms or conditions in a solicitation or contract for commercial products or commercial services in a manner that is inconsistent with customary commercial practice for the item being acquired unless a waiver is approved in accordance with agency procedures. The request for waiver must describe the customary commercial practice found in the marketplace, support the need to include a term or condition that is inconsistent with that practice and include a determination that use of the customary commercial practice is inconsistent with the needs of the Government. A waiver may be requested for an individual or class of contracts for that specific item. (d) Tailoring shall be by addenda to the solicitation and contract. The contracting officer shall indicate in Block27 a of the SF1449 if addenda are attached. These addenda may include, for example, a continuation of the schedule of supplies/services to be acquired from blocks 18 through 21 of the SF1449 ; a continuation of the description of the supplies/services being acquired; further elaboration of any other item(s) on the SF1449 ; any other terms or conditions necessary for the performance of the proposed contract (such as options, ordering procedures for indefinite-delivery type contracts, warranties, contract financing arrangements, etc.).
