DFARS Part 211: Describing Agency Needs

In plain English

DFARS Part 211 implements FAR Part 11 for DoD acquisitions, covering how agencies describe their needs in solicitations and contracts. It addresses brand name or equal descriptions, service contract identification, item unique identification (IUID) and valuation, and other requirements that affect how contractors prepare proposals and deliver items.

Key rules

• A justification and approval is required to use brand name or equal purchase descriptions when using sealed bidding or negotiated acquisition procedures, or simplified procedures for certain commercial products and services. (211.104)
• Purchase descriptions for service contracts must clearly distinguish Government employees from contractor employees, and contracts must require contractor personnel to identify themselves as contractor employees and display distinguishing badges or visible identification. (211.106)
• DoD solicitations that include military or Government-unique specifications and standards must use the provision at FAR 52.211-7, Alternatives to Government-Unique Standards. (211.107)
• A justification and approval is required to use proprietary specifications and standards when using sealed bidding or negotiated acquisition procedures, or simplified procedures for certain commercial products and services. (211.170)
• DoD item unique identification (IUID) or a recognized equivalent is required for all delivered items with a Government unit acquisition cost of $5,000 or more, for certain items under $5,000 when determined mission essential or controlled inventory, and regardless of value for serially managed items, embedded parts, parent items, warranted serialized items, and special tooling. (211.274-2)
• Contractors must identify the Government's unit acquisition cost for all deliverable end items to which IUID applies, using the contract unit price for fixed-price line items or the estimated fully burdened unit cost for cost-type, undefinitized, or time-and-materials line items. (211.274-3)
• The clause at 252.211-7003, Item Unique Identification and Valuation, must be used in solicitations and contracts for supplies and services involving the furnishing of supplies, including commercial acquisitions, unless an exception applies. (211.274-5)
• The clause at FAR 52.211-12, Liquidated Damages—Construction, must be used in all construction contracts exceeding $900,000, except cost-plus-fixed-fee contracts or contracts where the contractor cannot control the pace of the work; its use in contracts of $900,000 or less is optional. (211.503)

Who does what

In practice

• When bidding on DoD contracts, check if the solicitation includes brand name or equal or proprietary specifications; these require a justification and approval, which may affect the evaluation.
• If you are a service contractor, ensure your employees can clearly identify themselves as contractor personnel and have distinguishing badges or visible identification for meetings with Government personnel.
• For supplies, determine if your items require IUID marking based on the $5,000 threshold or other criteria, and include the cost of marking and valuation in your price.
• For construction contracts over $900,000, be aware that liquidated damages may apply unless the contract is cost-plus-fixed-fee or you cannot control the pace of the work.

Common pitfalls

• Assuming that brand name or equal descriptions can be used without a justification and approval; DFARS 211.104 requires one for sealed bidding, negotiated acquisitions, and certain simplified procedures.
• Failing to properly identify contractor employees in service contracts; DFARS 211.106 requires clear distinction and visible identification, and noncompliance can lead to personal services concerns.
• Overlooking IUID requirements for items under $5,000 that are mission essential or controlled inventory, or for embedded parts and serially managed items regardless of value.
• Not using the required clause at 252.211-7003 when it applies, which can result in noncompliant contracts and delivery issues.
