FAR 52.214-21—Descriptive Literature.
Plain-English Summary
FAR 52.214-21, Descriptive Literature, is a sealed bidding provision used when the Government needs bidders to submit product information that is necessary to evaluate whether the offered item is acceptable. It defines what counts as “descriptive literature,” explains the kinds of product details it is meant to show, and requires that the literature be identified to the correct item and received on time. The provision also states the consequences of failing to submit the literature, submitting it late, or submitting literature that does not demonstrate compliance with the solicitation. Alternate I adds a waiver concept for bidders offering a product previously supplied under a prior contract, including the information needed to request that waiver and the rule that a bidder must choose one basis for its bid before bid opening. In practice, this clause matters because it can be a strict responsiveness issue in sealed bidding: if the literature is required and not properly submitted, the bid may have to be rejected even if the price is otherwise favorable. It is designed to give the Government enough technical detail to evaluate the bid without turning the solicitation into a post-award clarification exercise.
Key Rules
Defines required literature
“Descriptive literature” means bidder-furnished information such as cuts, illustrations, drawings, and brochures that shows the product’s characteristics, construction, or operation. It is limited to information needed to evaluate acceptability and does not include operating or maintenance materials.
Used to evaluate acceptability
The literature is required to establish details of the offered product that are specified elsewhere in the solicitation and relate to significant elements such as design, materials, components, performance characteristics, and methods of manufacture, assembly, construction, or operation.
Must be identified and timely
When descriptive literature is required by the solicitation, it must be clearly identified to show which item(s) of the offer it applies to and must be received by the time stated in the solicitation. Proper identification is essential so the Government can match the literature to the bid item.
Late or missing literature can reject bid
If the bidder fails to submit required descriptive literature on time, the Government will reject the bid, subject only to the limited exception for late literature sent by mail under the Late Submissions, Modifications, and Withdrawals of Bids provision. This makes timely submission a responsiveness issue in sealed bidding.
Nonconforming literature means nonresponsive bid
If the literature does not show that the offered product conforms to the solicitation requirements, the Government must reject the bid. The literature must affirmatively demonstrate compliance; silence or ambiguity is not enough.
Waiver for previously supplied product
Under Alternate I, the Contracting Officer may waive the literature requirement if the offeror has previously supplied the same product under a prior contract. The bidder must provide specific prior-contract information to support the waiver request.
Must choose one basis before bid opening
A bidder may submit a bid based either on required descriptive literature or on a previously supplied product under the waiver provision, but not both as interchangeable options after bid opening. Once the bid opening deadline passes, the bidder cannot switch to the alternative basis, and the Government will disregard a waiver request if the bidder already submitted the requested literature.
Responsibilities
Contracting Officer
Include the provision when descriptive literature is needed under the solicitation and evaluate whether the literature submitted is timely, properly identified, and sufficient to show compliance. Under Alternate I, decide whether to waive the requirement for a previously supplied product and apply the sealed bidding rules on late submissions and bid responsiveness.
Bidder/Offeror
Submit the required descriptive literature by the solicitation deadline, clearly identify it to the correct bid item(s), and ensure it shows the offered product meets the stated requirements. If seeking a waiver under Alternate I, provide the required prior-contract information and choose the bid basis before the time set for receipt of bids.
Government Evaluators/Technical Personnel
Review the literature to determine whether the offered product’s design, materials, components, performance characteristics, and manufacturing or construction methods satisfy the solicitation’s stated requirements. Flag any gaps, ambiguities, or inconsistencies that prevent a finding of acceptability.
Agency/Procuring Activity
Use the provision only when descriptive literature is necessary for evaluation and ensure the solicitation clearly states what literature is required and when it must be received. Maintain consistency between the technical requirements in the solicitation and the literature needed to evaluate them.
Practical Implications
This clause can determine bid responsiveness, so missing or late literature can cost an otherwise low bidder the award.
Bidders should not assume brochures or marketing materials are enough; the literature must specifically show compliance with the solicitation’s required characteristics.
Identification matters: if the literature is not tied to the correct line item or product, the Government may not be able to use it to evaluate the bid.
Under Alternate I, bidders should decide early whether to rely on a waiver for a previously supplied product or on submitted literature, because they generally cannot switch after bid opening.
Contracting officers should be careful to request descriptive literature only when truly needed, because unnecessary requirements can create avoidable rejection risks and procurement delays.
Official Regulatory Text
As prescribed in 14.201-6 (p)(1) , insert the following provision: Descriptive Literature (Apr 2002) (a) "Descriptive literature," as used in this provision, means information furnished by a bidder, such as cuts, illustrations, drawings, and brochures, that shows a product’s characteristics or construction or explains its operation. The term includes only that information required to evaluate the acceptability of the product and excludes other information for operating or maintaining the product. (b) Descriptive literature is required to establish, for the purpose of evaluation and award, details of the product offered that are specified elsewhere in the solicitation and pertain to significant elements such as- (1) Design; (2) Materials; (3) Components; (4) Performance characteristics; and (5) Methods of manufacture, assembly, construction, or operation. (c) Descriptive literature, required elsewhere in this solicitation, shall be- (1) Identified to show the item(s) of the offer to which it applies; and (2) Received by the time specified in this solicitation. (d) If the bidder fails to submit descriptive literature on time, the Government will reject the bid, except that late descriptive literature sent by mail may be considered under the Late Submissions, Modifications, and Withdrawals of Bids provision of this solicitation. (e) If the descriptive literature fails to show that the product offered conforms to the requirements of the solicitation, the Government will reject the bid. (End of provision) Alternate I (Jan 2017) . As prescribed in 14.201-6 (p)(2), add the following paragraphs (f) and (g) to the basic provision: (f) The Contracting Officer may waive the requirement for furnishing descriptive literature if the offeror has supplied a product that is the same as that required by this solicitation under a prior contract. A bidder that requests a waiver of this requirement shall provide the following information: Prior contract number ____________ Date of prior contract ____________ Line item number of product supplied ______ Name and address of Government activity to which delivery was made ___________________________ Date of final delivery of product supplied ____________ (g) Bidders shall submit bids on the basis of required descriptive literature or on the basis of a previously supplied product under paragraph (f) of this provision. A bidder submitting a bid on one of these two bases may not elect to have its bid considered on the alternative basis after the time specified for receipt of bids. The Government will disregard a bidder's request for a waiver under paragraph (f) if that bidder has submitted the descriptive literature requested under this solicitation.
