When procuring a product, each agency shall procure products that comply with the provisions in these standards when such products are available in the commercial marketplace or when such products are developed in response to a Government solicitation. Agencies cannot claim a product as a whole is not commercially available because no product in the marketplace meets all the standards. If products are commercially available that meet some but not all of the standards, the agency must procure the product that best meets the standards.The concept of commercial availability is based on existing provisions in the FAR (see 48 CFR 2.101, Definitions of Words and Terms: Commercial item).
Similar to an undue burden analysis, agencies cannot claim that a product as a whole is not commercially available because no product in the marketplace meets all the standards. If products are commercially available that meet some but not all of the standards, the agency must procure the product that best meets the standards.
