FAR Part 16: Exceptions to Fair Opportunity

When the Government awards a multiple-award IDIQ contract, it creates a pool of pre-competed vendors. Each time you place an order, you are supposed to give every contract holder a fair opportunity to compete for that order. FAR 16.507-6 lists the specific exceptions that let you skip that process and go directly to one contractor.

The Basics

Exceptions to Fair Opportunity

The statutory exceptions for IDIQ orders, what to document, approval thresholds, and how this differs from Parts 6 and 8.

1 What Is Fair Opportunity?

When the Government awards a multiple-award IDIQ contract, it creates a pool of pre-competed vendors. Each time you place an order, you are supposed to give every contract holder a fair opportunity to compete for that order. Think of it as a mini-competition within an already competed vehicle. The exceptions in FAR 16.507-6 let you bypass this mini-competition and go directly to one of the IDIQ holders. These exceptions only apply to multiple-award IDIQs. Single-award IDIQs do not need fair opportunity because there is only one awardee.


2 The Statutory Exceptions

FAR 16.507-6(b) lists the exceptions that permit an order or BPA valued above the micro-purchase threshold to be placed on a sole source basis:

(1) The agency need for the supplies or services is so urgent that providing a fair opportunity would result in unacceptable delays.

(2) Only one awardee is capable of providing the supplies or services required at the level of quality required because the supplies or services ordered are unique or highly specialized.

(3) The order must be issued on a sole-source basis in the interest of economy and efficiency because it is a logical follow-on to an order already issued under the contract, provided that all awardees were given a fair opportunity to be considered for the original order.

(4) It is necessary to place an order to satisfy a minimum guarantee.

(5) For orders exceeding the SAT, a statute expressly authorizes or requires that the purchase be made from a specified source.

(6) For DoD, NASA, and the Coast Guard, the order satisfies one of the exceptions permitting the use of other than full and open competition listed in Part 6.103 (10 U.S.C. 3406(c)(5)).

In operational contracting, you will most commonly encounter exceptions (1), (2), and (3). Exception (4) comes up occasionally when you need to make sure a contractor's minimum order guarantee is met before the contract expires. Exception (5) applies to statutory set-asides above the SAT.

Small business note: Part 19 and Public Law 111-240 (15 U.S.C. 644(r)) provide authority for setting aside orders and placing orders under reserves. These are not subject to the justification, approval, and posting requirements that apply to exceptions (1) through (6). That authority runs through a different lane entirely.

3 Documentation: Below vs. Above the SAT

The documentation burden depends on the dollar value of the order.

Orders above the micro-purchase threshold but at or below the SAT: The contracting officer documents the basis for using the exception. There is no formal template required. If you are using the logical follow-on exception, you must describe why the relationship between the initial order and the follow-on is logical in terms of scope, period of performance, or value.

Orders above the SAT: You need a formal written justification that includes the ten elements listed in FAR 16.507-6(d)(2). These are similar to what you would see in a Part 6 J&A: identification of the contracting activity, description of the requirement with estimated value, the exception being cited with supporting rationale, a fair and reasonable price determination, and the CO's certification.

Do not confuse this with a FAR Part 6 J&A. Part 6 does not apply to orders under IDIQ contracts. The authority here comes from Part 16, and the documentation follows 16.507-6 requirements. Using the wrong template or citing Part 6 for an IDIQ order is a common mistake.

4 How This Differs from Parts 6 and 8

Each FAR Part has its own lane for restricting competition, and each lane has its own name for the sole source document:

FAR Part 6: Justification and Approval (J&A). Non-commercial, open market procurements above the SAT.

FAR Part 8: Limited Sources Justification. Orders from Federal Supply Schedules (GSA).

FAR Part 12: Commercial Sole Source Justification. Commercial item buys using simplified procedures.

FAR Part 16: Exception to Fair Opportunity. Task and delivery orders off IDIQ and requirements contracts.

People use the term "J&A" for all of these interchangeably, but a sharp contracting officer hears "Part 6, non-commercial, open market" when someone says J&A. They hear "probably a GSA order" when they hear limited sources justification. They hear "task or delivery order off an IDIQ" when they hear exception to fair opportunity. Getting the terminology right matters because it tells you which FAR Part governs your documentation, your exceptions, and your approval chain.

If you are ordering from a GSA schedule, use Part 8. If you are ordering from a multiple-award IDIQ, use Part 16. Only reach for Part 6 when you are doing a standalone open market buy above the SAT.


5 What Goes Into an Over-the-SAT Justification

For orders valued above the SAT, FAR 16.507-6(d)(2) requires a written justification that includes, at minimum, the following ten elements:

(i) Identification of the agency and contracting activity, and specific identification of the document as a "Justification for an Exception to Fair Opportunity."

(ii) Nature and/or description of the action being approved.

(iii) A description of the supplies or services required to meet the agency's needs, including the estimated value.

(iv) Identification of the exception to fair opportunity and the supporting rationale, including a demonstration that the proposed contractor's unique qualifications or the nature of the acquisition requires use of the exception cited. If using the logical follow-on exception, the rationale must describe why the relationship between the initial order and the follow-on is logical.

(v) A determination by the contracting officer that the anticipated cost to the Government will be fair and reasonable.

(vi) Any other facts supporting the justification.

(vii) A statement of the actions, if any, the agency may take to remove or overcome any barriers that led to the exception to fair opportunity before any subsequent acquisition.

(viii) The contracting officer's certification that the justification is accurate and complete to the best of the contracting officer's knowledge and belief.

(ix) Evidence that any supporting data from technical or requirements personnel (verifying minimum needs or rationale for the exception) has been certified as complete and accurate by those personnel.

(x) A written determination by the approving official that one of the exceptions applies to the order.

These ten elements map closely to a Part 6 J&A but are scoped to the Part 16 exceptions. Element (iv) is the heart of the document. Everything else is administrative scaffolding around it.

If exception (1) applies (urgency), remember this: The exception does not give you permission to skip competition entirely. You still must request offers from as many sources as practicable. The exception only allows you to shorten the response time so that an unacceptable delay is avoided. You must still conduct market research and attempt to solicit from multiple IDIQ holders, even if you are compressing the evaluation window.

6 Approval Thresholds

FAR 16.507-6(e) sets the approval levels based on the estimated value of the order:

Above the SAT but not above $900,000: The ordering activity contracting officer's certification serves as approval, unless a higher level is established by agency procedures.

Above $900,000 but not above $20M: The advocate for competition of the activity placing the order. This authority is not delegable.

Above $20M but not above $90M ($150M for DoD, NASA, Coast Guard): The head of the procuring activity placing the order, or a designee who is a general/flag officer or civilian serving above GS-15.

Above $90M ($150M for DoD, NASA, Coast Guard): The senior procurement executive of the agency placing the order. Not delegable, except for the Under Secretary of Defense for Acquisition and Sustainment.

Agencies may delegate the lower thresholds differently. Check your local policy for specific delegation guidance at your activity.


7 Items Peculiar to One Manufacturer

FAR 16.507-7 covers brand-name restrictions on IDIQ orders. This is Part 16's version of a brand-name justification.

The contracting officer must justify restricting consideration to an item peculiar to one manufacturer, such as a particular brand name, product, or feature. A brand-name item is considered peculiar to one manufacturer even if it is available on more than one contract. Brand-name specifications must not be used unless the particular brand, product, or feature is essential to the Government's requirements and market research indicates other companies' similar products do not meet, or cannot be modified to meet, the agency's needs.

Brand-name justifications follow the same format and approval requirements from 16.507-6(d) through (e), modified to show the brand-name justification. For orders over $40,000, the contracting officer must either post the justification on the agency solicitation website or provide it to all contract awardees with the solicitation.

Do not confuse the exception for unique capability with a brand-name restriction. Exception (2) in 16.507-6(b) applies when only one awardee can perform the work because of unique qualifications. A brand-name restriction under 16.507-7 applies when you are specifying a particular manufacturer's product. The facts, authorities, and documentation differ. Getting the classification wrong will route your justification through the wrong process.

Narrative for Exception (B)
Task Order 0003, currently performed by Vendor Alpha under this IDIQ, includes migration of the base Exchange server to a DoD-approved zero-trust architecture using Microsoft Azure Government. Vendor Alpha holds the only FedRAMP High JAB P-ATO for Azure Government migration services among the three IDIQ holders. Vendor Beta and Vendor Gamma were contacted on 15 Jan 2026 and confirmed in writing that they do not currently hold FedRAMP High authorization for Azure Government environments and could not obtain it within the project timeline. The migration is 60 percent complete with a go-live date of 1 Apr 2026. Switching vendors mid-migration would require the new vendor to obtain FedRAMP High authorization (estimated 6 to 9 months), repeat the Assessment and Authorization process for the partially migrated environment, and delay the USCYBERCOM-directed zero-trust compliance deadline of 30 Sep 2026.
Market Research
All three IDIQ holders were contacted regarding FedRAMP High authorization for Azure Government. Vendor Alpha provided current JAB P-ATO certificate (issued 12 Aug 2025, valid through 11 Aug 2028). Vendor Beta confirmed via email (18 Jan 2026) that FedRAMP High authorization is not in their current assessment pipeline. Vendor Gamma confirmed via email (20 Jan 2026) that they hold FedRAMP Moderate but not High for Azure environments.
Actions to Increase Competition
For future task orders requiring cloud migration services, the contracting officer will include FedRAMP High authorization as an evaluated subfactor in fair opportunity proposals, incentivizing all IDIQ holders to pursue authorization.
Contracting Officer Determination: I have determined that only one awardee is capable of providing the services required per FAR 16.507-6(b)(2).
