FAR 4.403—Responsibilities of contracting officers.
Plain-English Summary
FAR 4.403 assigns the contracting officer’s core security duties when a procurement may involve classified information. It covers the presolicitation review for possible access to classified information, the special steps required when another agency’s classified information may be involved, and the need to follow either the National Industrial Security Program (NISP) or the relevant agency’s security procedures. It also addresses the solicitation phase, including ensuring the classified acquisition is handled properly and inserting the required Security Requirements clause and any additional safeguards. Finally, it covers the award phase, where the contracting officer must inform contractors and subcontractors of the applicable classification markings and security requirements for documents, tasks, subcontracts, and components, including use of DD Form 254 for DoD and certain nondefense agencies with DoD industrial security agreements. In practice, this section is about making sure security requirements are identified early, documented correctly, and flowed down properly so classified work can be competed, awarded, and performed without security lapses or unauthorized disclosure.
Key Rules
Review for classified access early
Before issuing a solicitation, the contracting officer must review the proposed acquisition to determine whether offerors or the contractor during performance may need access to classified information. This early screening is intended to ensure the right security procedures are in place before the procurement moves forward.
Use the right security regime
If another agency’s classified information may be involved, the contracting officer must determine whether that agency is covered by the NISP and then follow that agency’s procedures for determining firm clearances. If the contracting officer’s own agency controls the classified information, agency procedures govern.
Ensure classified acquisition compliance
During the solicitation phase, the contracting officer must make sure the acquisition is conducted in accordance with the NISP or applicable agency procedures. This means the security process is not optional or informal; it must be integrated into the procurement from the start.
Include required security clauses
Solicitations must include an appropriate Security Requirements clause, and when needed, additional security safeguards beyond the standard clause at FAR 52.204-2. The clause and any extra safeguards should match the sensitivity and handling needs of the classified work.
Document classification at award
At award, the contracting officer must inform contractors and subcontractors of the security classifications and requirements assigned to documents, materials, tasks, subcontracts, and components identified in the requirement documentation. This ensures the contractor knows exactly what must be protected and how.
Use DD Form 254 when required
For DoD components and nondefense agencies with industrial security services agreements with DoD, the Contract Security Classification Specification, DD Form 254, must be used. The contracting officer or authorized agency representative is the approving official for the prime contract DD Form 254 and must ensure it is properly prepared, distributed, and coordinated with security personnel.
Follow non-NISP agency procedures
For agencies not covered by the NISP, the contracting officer must follow that agency’s own procedures. The section preserves agency-specific security processes where the NISP does not apply.
Responsibilities
Contracting Officer
Review proposed solicitations for possible access to classified information; determine whether another agency’s classified information is involved; follow the correct agency or NISP procedures; ensure the solicitation includes the proper Security Requirements clause and any additional safeguards; and, at award, inform contractors and subcontractors of the applicable classifications and security requirements.
Authorized Agency Representative
When designated, approve the DD Form 254 for the prime contract and ensure it is properly prepared, distributed, and coordinated with requirements and security personnel in accordance with agency procedures.
Agency Security Personnel
Support the contracting officer in applying agency security procedures, preparing classification guidance, and coordinating the security requirements that must be reflected in the solicitation and contract documents.
Contractor and Subcontractors
Receive and comply with the classification markings, handling requirements, and security safeguards identified for the contract, including any flowdown requirements to subcontractors and components.
DoD Components and Covered Nondefense Agencies
Use DD Form 254 for classified contracts and follow the required coordination and approval process for industrial security services agreements with DoD.
Practical Implications
Security review must happen before the solicitation goes out; waiting until award can cause delays, rework, or an invalid procurement package.
The biggest compliance risk is using the wrong security framework—NISP, another agency’s procedures, or agency-specific rules—so the contracting officer must identify the controlling regime early.
A standard Security Requirements clause may not be enough for all classified work; additional safeguards may need to be added to address special handling, storage, transmission, or access controls.
DD Form 254 is a critical control document for DoD-related classified contracting, and errors in preparation, approval, or distribution can create downstream performance and security problems.
Contractors need clear, specific classification guidance at award so they can protect information correctly and flow requirements to subcontractors without guesswork.
Official Regulatory Text
(a) Presolicitation phase . Contracting officers shall review all proposed solicitations to determine whether access to classified information may be required by offerors, or by a contractor during contract performance. (1) If access to classified information of another agency may be required, the contracting officer shall- (i) Determine if the agency is covered by the NISP; and (ii) Follow that agency’s procedures for determining the security clearances of firms to be solicited. (2) If the classified information required is from the contracting officer’s agency, the contracting officer shall follow agency procedures. (b) Solicitation phase . Contracting officers shall- (1) Ensure that the classified acquisition is conducted as required by the NISP or agency procedures, as appropriate; and (2) Include- (i) An appropriate Security Requirements clause in the solicitation (see 4.404); and (ii) As appropriate, in solicitations and contracts when the contract may require access to classified information, a requirement for security safeguards in addition to those provided in the clause (52.204-2, Security Requirements). (c) Award phase . Contracting officers shall inform contractors and subcontractors of the security classifications and requirements assigned to the various documents, materials, tasks, subcontracts, and components of the classified contract as identified in the requirement documentation as follows: (1) Nondefense agencies that have industrial security services agreements with DoD, and DoD components, shall use the Contract Security Classification Specification, DD Form 254. The contracting officer, or authorized agency representative, is the approving official for the DD Form 254 associated with the prime contract and shall ensure the DD Form 254 is properly prepared, distributed by and coordinated with requirements and security personnel in accordance with agency procedures, see 4.402 (d)(1). (2) Contracting officers in agencies not covered by the NISP shall follow agency procedures.
